Description

Technical Field

[0001] The utility model relates to the technical field of flat screen machines, and more specifically to a high-efficiency flat screen machine. Background Art

[0002] Flat screen machine is an important equipment used for material screening and grading. Its working principle is mainly to use the vibration or shaking of the screen surface to make the material move relative to the screen surface, so as to separate and screen the material according to its particle size, thus achieving material screening and grading.

[0003] The flat screen machine is usually composed of a screen body, a vibrating device, a transmission device, a base, etc. The screen body is the main part of the flat screen machine, and multiple layers of screens are installed inside it. The aperture size of the screen can be adjusted as needed to meet the screening requirements of different materials.

[0004] However, during the screening process, the channels of the screen grids inside the flat screen machine in the prior art occupy a considerable portion of the screen body space, reducing the effective screening area of ​​the equipment, resulting in a decrease in the screening processing capacity and work efficiency. In view of this, we propose an efficient flat screen machine. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a high-efficiency flat screen machine to solve the technical problem that in the current flat screen machine, during the screening process, the channels provided by the screen grids inside the flat screen machine occupy a considerable part of the screen body space, reducing the effective screening area of ​​the equipment, resulting in a decrease in screening processing capacity and work efficiency.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: an efficient flat screen machine, comprising a bracket and a multi-stage screening mechanism fixedly installed in the bracket;

[0007] The multi-stage screening mechanism comprises a shell, both ends of which are fixedly mounted with vibration motors, and the top of the shell is located at a high position and connected to an upper hopper;

[0008] Three partitions are equidistantly constructed on one side of the shell body close to the upper hopper, and the bottom end of the shell body is located at a low position and is equidistantly connected to the lower hopper A, the lower hopper B, and the lower hopper C. Screen grid mechanisms are obliquely fixedly installed between the three partitions and the corresponding lower hoppers A, B, and C, and one side of the bottom end of the shell body is connected to the lower hopper D;

[0009] The three sieve grid mechanisms cooperate with lower hopper A, lower hopper B, lower hopper C, and lower hopper C to form a primary filter chamber, a secondary filter chamber, a tertiary filter chamber, and a discharge chamber from top to bottom in the shell, thereby realizing multi-stage filtering of the material.

[0010] The utility model realizes multi-stage filtration of materials by the cooperation of a plurality of sieve grid mechanisms in a shell and lower hoppers A, B, C and D, and by two vibration motors, materials entering the shell are gradually filtered through the three sieve grid mechanisms, and the filtered materials are discharged through the lower hoppers A, B and C in sequence, so that the filtered materials are discharged through the lower hoppers D. The three sieve grid mechanisms are arranged between the three partitions and the lower hoppers A, B and C through a centralized design, and the stacked arrangement greatly reduces the occupation of the screen body space, increases the effective screening area of ​​the equipment, and improves the screening processing capacity and working efficiency of the equipment.

[0011] Preferably, an inspection opening is provided in the center of the top end of the shell, and an inspection cover for sealing the inspection opening is hingedly mounted on the top of the shell.

[0012] Preferably, two supports are symmetrically constructed on both sides of the bottom end of the inspection cover, and springs are fixedly installed at the ends of the supports, and the springs abut against the screen grid mechanism.

[0013] Preferably, a plurality of guide inclined plates are symmetrically and equidistantly configured on both sides of the inner bottom end of the upper hopper, and the guide inclined plates are obliquely arranged at the inner bottom of the upper hopper.

[0014] Preferably, two support arms are symmetrically constructed on both sides of the shell, and the support arms are fixedly connected to the bracket.

[0015] Preferably, the screen grid mechanism comprises two frames, each of which is provided with a supporting grid, and screens abutting against the supporting grids are fixedly mounted on both sides of the frames, and two supporting frames are symmetrically configured on both sides of the top of the screen.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model uses the cooperation of multiple sieve grid mechanisms in the shell and lower hoppers A, B, C and D. Through two vibration motors, the materials entering the shell are gradually filtered through the three sieve grid mechanisms. The filtered materials are discharged through the lower hoppers A, B and C in sequence, thereby realizing multi-stage filtration of the materials. The filtered materials are discharged through the lower hopper D. Through a centralized design, the three sieve grid mechanisms are arranged between the three partitions and the lower hoppers A, B and C. The stacked arrangement greatly reduces the occupation of the screen space, increases the effective screening area of ​​the equipment, and improves the screening processing capacity and work efficiency of the equipment.

[0018] 2. The utility model also screens the material through the screening grid mechanism. During the screening process, the material is filtered through two screens, and the excessive amplitude of the vibration generated by the two vibration motors acting on the two screens is absorbed by the supporting grid, thereby increasing the service life of the screens.

A sieve grid mechanism 3 is fixedly installed between the three partitions 204 and the corresponding lower hoppers A205, B206, and C207, and a lower hopper D208 is connected to one side of the bottom end of the shell 201. The three sieve grid mechanisms 3 cooperate with the lower hoppers A205, B206, C207, and C207 on the shell. A primary filter chamber, a secondary filter chamber, a tertiary filter chamber, and a discharge chamber are formed from top to bottom in the shell 201 to achieve multi-stage filtering of the material. Through the cooperation of multiple sieve grid mechanisms 3 in the shell 201 and the lower hoppers A205, B206, C207, and D208, the material entering the shell 201 is gradually filtered through the three sieve grid mechanisms 3 through two vibration motors 202. The filtered material is discharged through the lower hopper A205, B206, and C207 in turn to achieve multi-stage filtering of the material. The filtered material is discharged through the lower hopper D208. Through a centralized design, the three sieve grid mechanisms 3 are arranged between the three partitions 204 and the lower hoppers A205, B206, and C207.
