Embodiment Construction

[0019] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and together with the embodiments of the present invention are used to explain the principle of the present invention and are not intended to limit the scope of the present invention.

[0020] See figure 1 and figure 2 , The self-cleaning trommel screen includes a filter cylinder 1, a frame 2, a rotating mechanism 3, a guide body 4 and a spray device 5, which are used to wash materials and separate soluble substances and insoluble substances in the materials.

[0021] In this embodiment, the filter cartridge 1 includes a cylinder body 11 and a filter screen 12 . The cylinder 11 is a hollow cylinder, and inside the cylinder 11 there is a filter chamber connected to the two ends of the cylinder 11 along the axial direction, and the two ends form the inlet and outlet of the m...

Abstract

The invention relates to a self-cleaning drum screen. The self-cleaning drum screen comprises a filter cartridge, a rotating mechanism and a flow guide body, the filter cartridge comprises a cartridge body and a filter screen body, the cartridge body is of a cylindrical structure, a filter cavity enabling the two ends of the cartridge body to communicate with each other is formed in the cartridge body in the axis direction of the cartridge body, filter holes are formed in the side wall of the cartridge body and communicate with the filter cavity, the filter screen body is fixedly connected to the cartridge body and covers the filter holes, the cartridge body is obliquely arranged, the rotating mechanism is in transmission connection with the cartridge body and can drive the cartridge body to rotate around the axis of the cartridge body, the flow guide body is in a spiral line shape and is coaxially and fixedly arranged on the inner wall of the cartridge body, and the spiral direction of the flow guide body is the same as the rotating direction of the cartridge body. According to the self-cleaning drum screen, the spiral-line-shaped flow guide body is arranged in the cartridge body, when the cartridge body rotates, the flow guide body also rotates along with the cartridge body, the spiral flow guide body plays a flow guide role in the cartridge body, materials are promoted to move downwards in the rotating process of the cartridge body and fall off from an opening in the lower end of the cartridge body, and the phenomenon that the materials are attached to the inner wall of the cartridge body to influence the filtering and separating effect can be avoided.

Description

technical field [0001] The invention relates to the technical field of drum screens, in particular to a self-cleaning drum screen. Background technique [0002] Drum sieve is a kind of machinery widely used in sorting technology, which controls the sorting by particle size. If it meets the requirements of the pore size, the particles can pass through the sieve and achieve the purpose of drum sieving. For example, a drum sieve can be used to drain the water in the material, so that the soluble and insoluble substances in the material can be separated. [0003] In the process of using the current trommel screen, in order to control and improve the screening efficiency, the speed of material moving in the trommel screen should not be too fast, otherwise it will cause insufficient and incomplete screening, so the trommel screen generally has relatively strict regulations. The installation inclination, generally speaking, this angle is about 5°. [0004] Although such a settin...
