Our company designed a compost trommel screen, belongs to the organic compost processing device, the screen cylinder is installed on the bracket, and the ground is 0.5° -4° Angle, the front, back and lower end of the screen cylinder is provided with a feed port, large discharge port and under the screen material discharge port; The outside of the screen cylinder body is equipped with an outer shield, and the blocking plate is installed inside the outer shield on both sides of the axis of the screen cylinder body; The inner wall of the outer shield is provided with a screen cylinder body skeleton, and the screen lattice is clamped on the screen cylinder body skeleton to form a cylinder face. The utility model has the advantages that the screen can effectively screen and remove the waste and waste in the organic compost, and it is easy to replace, and the material blocking plate can effectively prevent the crushing and bending of the long garbage, and prevent the damage of the outer shield of the large screen.
The compost trommel screen comprises a transmission, a bracket, and a polygonal cross section driven by the transmission
The screen cylinder body, outer guard, feed port, large compost outlet and under the screen material outlet, the screen cylinder body is installed on the bracket, the screen cylinder body and the ground is 0. 5°-4° Angle, the front end of the screen cylinder body is provided with a feed port, the screen cylinder body is provided with under the screen material outlet, the screen cylinder body is provided with a large outlet; The screen cylinder body is characterized in that the external set of an outer shield, screen cylinder axis on both sides of the outer shield is installed in the material plate; The inner wall of the outer shield is provided with a screen cylinder body skeleton, and the screen lattice is clamped on the screen cylinder body skeleton to form a cylinder face.
Compost trommel screen is a commonly used waste separation device, which can take advantage of different waste particle sizes to effectively separate waste, featuring high screening accuracy and good separation efficiency. compost trommel screen device according to the size of different particle size of garbage screening at the same time, can screen out three kinds of materials and above at the same time, to achieve a machine multi screen, small and medium fine material classification effect, not easy to plug the sieve, large processing capacity, but it has certain requirements for garbage, that is not suitable for heavy, large construction waste, Otherwise, it will directly affect the screening effect and equipment life, increase the amount of equipment maintenance. At present, organic composting plants commonly used to eliminate large methods are: ① manual: low efficiency, high labor intensity; (2) no power bar screen: low efficiency, large easy to entrain small materials; (3) Vibration bar screen: high requirements for the equipment foundation, high noise, large dust.
In view of the above problems, we designed to provide a large compost trommel screen specially used for construction waste separation, to solve the existing screening machine can not contain heavy, large construction waste more effective removal, dust, separation efficiency is not high problems.
The operating principle and process of the compost trommel screen we designed are as follows: Organic compost into the screening machine, the rotating drum can be compost tossing, continuous tossing can be effective screening of compost, more than the screen for large garbage, large in the large screen at the end of the large discharge port 8 discharge, dust cover 6 can effectively prevent the material on the screen falling into the discharge port 8 dust; The rest of the compost is output through the screening machine under the screen screen 12 under the material outlet 11, the enhanced screen can effectively screen the large waste, to prevent the destruction of large compost on the subsequent equipment; When the length of compost, compost and screen is not good separation, with the rotation of the drum, long compost in the rotation of the sieve cylinder 10 and block plate 7 block broken, by screening machine sieve 12 under the screen under the discharge port 11 output, avoid long compost from the sieve 12 channel out of the sieve cylinder 10 impact, resulting in damage to the sieve cylinder 10 or other dangers.
