Description

Technical Field

[0001] The present invention relates to the technical field of material screening equipment, and particularly relates to a horizontal drum screening machine. Background Art

[0002] A horizontal drum screening machine is a device used for material screening, mainly used in industries such as feed mills, mines, building materials, and metallurgy. The working principle of the horizontal drum screening machine is that the drum axis is driven by a motor to make a rotational motion, and the reduction gear adjusts the cylinder to rotate at a certain speed. The material enters the cylinder from the feed port. Under the action of the centrifugal force generated by the rotation, the material tumbles in the cylinder and is separated through the grading screen mesh. Due to the different grading sizes of the screen mesh, the materials are gradually separated and screened. In addition, it is applicable to various properties of materials, especially wet and easily blocked materials such as coal, coke, and lime.

[0003] In the prior art, when the horizontal drum screening machine is in use, the material is screened by the rotation of the screening drum inside it. The common screening drum is generally circular. Then, after the material enters its interior, gravity causes the material to slide along the inner wall surface of the drum and accumulate at the bottom of the drum. At this time, with the rotation of the drum and the downward pressure of the material weight, the large-particle materials at the bottom of the drum will be pressed into the screening holes of the drum, resulting in the blockage of the screening holes of the drum. Although some screening machines can vibrate the drum to reduce the occurrence of screening hole blockage, in the case of a large amount of material, the material will float up and down with the vibration of the drum. At this time, the weight of the upper-layer material will repeatedly press down on the surface of the lower-layer material, and then the materials with unqualified particle size will be pressed out of the screening holes of the drum, thus affecting its screening accuracy and screening effect. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a horizontal drum screening machine to solve the problems raised in the above background art.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: A horizontal drum screening machine includes a frame. A housing is fixedly installed on the top surface of the frame. A first conveyor is fixedly installed inside the frame. A second conveyor is arranged on one side of the first conveyor. A screening drum is rotatably connected inside the frame; Two installation cylinders are rotatably connected inside the frame. A number of receiving plates are rotatably connected inside the installation cylinder. A mounting strip is fixedly installed on one side of the receiving plate. A steel brush plate is fixedly installed on one side of the mounting strip. A number of hinge seats are fixedly installed on one side of the receiving plate; A mounting tube is rotatably connected to the inside of each of the two mounting cylinders. A plurality of connecting blocks are fixedly installed on the outer circumferential wall surface of the mounting tube. The connecting blocks are rotatably connected to the hinge seats. The mounting tube penetrates to the outside of the housing. Two adjusting heads are arranged on one side of the housing. The positions of the two adjusting heads correspond to the positions of the two mounting tubes respectively; A limiting component is arranged inside the mounting tube and is used for limiting after the use angle of the steel brush plate is adjusted; A driving component is arranged inside the frame and is used for driving a plurality of steel brush plates and the screening drum to rotate simultaneously.

[0006] By adopting the above technical solution, during use, the staff puts the material into the inside of the screening drum through the feed hopper. Then, the staff makes the screening drum rotate through the driving component. After that, the material inside the screening drum will be displaced as the screening drum rotates. At this time, part of the material will fall onto the surface of the first conveyor through the screening holes on the surface of the screening drum. Then, the screened material will be conveyed through the conveyor belts of the first conveyor and the second conveyor, so as to achieve the effect of screening the material. During this process, the driving component will synchronously drive the two mounting cylinders and the plurality of steel brush plates outside them to rotate while the screening drum rotates. Then, the plurality of rotating steel brush plates will be inserted into the screening holes of the screening drum and dredge the blocked material inside it to prevent it from being blocked and stuck, which affects the use. When the materials inside the screening drum are different, the staff rotates the mounting tube. Then, the plurality of connecting blocks on the surface of the mounting tube will drive the plurality of steel brush plates to rotate through the plurality of hinge seats, so as to adjust the use angles of the plurality of steel brush plates, making it convenient to dredge different materials to prevent blockage.

Then, the staff can rotate the installation rod. At this time, under the limiting action of the positioning disk and the plurality of limit frames, the rotating installation rod will drive the installation tube to rotate and complete the angular socket connection of the multiple steel brush plates. After the above steps are completed, the installation rod is reset by the elasticity of the first spring.
