Abstract
Description
Technical Field
[0001] This utility model belongs to the field of spiral centrifuge technology, specifically an anti-clogging spiral centrifuge. Background Technology
[0002] As a highly efficient solid-liquid separation device, the screw centrifuge is widely used in various industrial fields such as chemical, food, environmental protection, and pharmaceutical industries due to its advantages such as high separation efficiency, strong processing capacity, and stable operation. Its core working principle is to use the centrifugal force generated by high-speed rotation to quickly separate the solid particles and liquid phase in the material, thereby achieving the purification of materials or the environmental treatment of waste. In the operation process of the screw centrifuge, the smoothness of the feeding system and the effect of material pretreatment directly determine the operating efficiency, service life and maintenance cost of the equipment, and are the key links to ensure the continuous and stable operation of the equipment.
[0003] Meanwhile, a horizontal spiral centrifuge with application number CN202222052095.4 includes an installation plate for placing the horizontal spiral centrifuge body, and further includes: a support assembly, the support assembly being installed at the bottom of the installation plate, the support assembly including a support column, the bottom of the support column having an installation groove, an adjusting column being installed in the installation groove, the bottom of the adjusting column being provided with rollers, the adjusting column being connected to an adjusting assembly for adjusting the vertical height of the adjusting column; and a placement plate installed on the installation plate, the placement plate being connected to the upper surface of the installation plate through a shock-absorbing assembly, and the horizontal spiral centrifuge body being fixedly installed on the placement plate.
[0004] However, the following problems were found in the implementation of the relevant technologies: Current spiral centrifuges are prone to clogging when centrifuging materials because the materials contain certain large structures, which cause differences from fine materials. If a screening structure is not set up, large particles will easily clog the spiral centrifuge when centrifuged together with small particles for a long time. The aforementioned horizontal spiral centrifuge has certain shortcomings. Although it realizes the movement of the spiral centrifuge position, it does not solve the problem of spiral centrifuge clogging. As a result, once the spiral centrifuge is clogged during use, maintenance is required, which inevitably affects the centrifugation effect of the materials. Utility Model Content
[0005] To address the problems mentioned in the background section, this invention provides an anti-clogging spiral centrifuge, which has the advantage of reducing the probability of clogging in the spiral centrifuge.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging spiral centrifuge, comprising a spiral centrifuge body, a feed pipe connected to the top of the spiral centrifuge body, a feed cylinder connected to the top of the feed pipe, a screening component and a reset component respectively provided on the feed cylinder, a feed hopper connected to the top of the feed cylinder, a fixing plate connected to one side of the spiral centrifuge body, a collection box connected to the top of the fixing plate, a discharge pipe connected to one side of the collection box, a discharge valve connected to the surface of the discharge pipe, and a drive source connected to the inner wall of one side of the feed cylinder; The surface of the screening component is poweredly connected to the power output terminals of the two drive sources for screening materials. The surface of the reset component is connected to the surface of the screening component to drive the screening component to spring back and reset in the vertical direction.
[0007] Preferably, the screening assembly includes two cams and two support plates. The two cams are respectively disposed on the power output ends of the two drive sources, the surfaces of the two support plates are respectively in contact with the surfaces of the two cams, and a screening plate is connected between the two support plates.

[0012] Preferably, the other side of the feed cylinder is connected to the other side of the collection box, and the inner side of the feed cylinder is connected to the inner side of the collection box.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The shape and characteristics of the cam in this invention facilitate the upward movement of the screening plate driven by the support plate.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] like Figures 1 to 6As shown, this utility model provides an anti-clogging spiral centrifuge, including a spiral centrifuge body 1. The top of the spiral centrifuge body 1 is connected to a feed pipe 4, and the top of the feed pipe 4 is connected to a feed cylinder 5, which facilitates the expansion of the feeding space, the concentrated entry of materials and the prevention of overflow. The feed cylinder 5 is respectively provided with a screening component 2 and a reset component 3. The top of the feed cylinder 5 is connected to a feed hopper 6. A fixing plate 7 is connected to one side of the spiral centrifuge body 1, and the top of the fixing plate 7 is connected to a collection box 8, which facilitates the timely collection of impurities after screening and avoids the accumulation of impurities causing blockage. A discharge pipe 9 is connected to one side of the collection box 8, and a discharge valve 10 is connected to the surface of the discharge pipe 9, which facilitates the control of impurity discharge and improves the operational flexibility. A drive source 11 is connected to the inner wall of one side of the feed cylinder 5. The surface of the screening component 2 is poweredly connected to the power output ends of the two drive sources 11 for screening materials; The surface of the reset component 3 is connected to the surface of the screening component 2 to drive the screening component 2 to spring back and reset in the vertical direction.
[0018] Specifically, the screening component 2 includes two cams 21 and two support plates 22. The two cams 21 are respectively set on the power output ends of the two drive sources 11. The screening action is easily realized by the rotation of the cams 21. The structure is simple and the transmission is reliable. The surfaces of the two support plates 22 are respectively in contact with the surfaces of the two cams 21. A screening plate 23 is connected between the two support plates 22. The screening plate 23 is fixed by the support plates 22, which helps to enhance the structural strength of the screening plate 23 and improve the screening stability.
[0019] Furthermore, the reset assembly 3 includes six support rods 31. All six support rods 31 are located inside the feed cylinder 5. The multiple support rods 31 facilitate the stable guidance for the reset action. The surfaces of four support rods 31 are fitted with expansion springs 32, and the surfaces of the other two support rods 31 are fitted with contraction springs 33. The elastic force of the expansion springs 32 and contraction springs 33 facilitates the reset.
[0020] Furthermore, the surfaces of four support rods 31 are slidably connected to the inner side of one of the support plates 22, which facilitates the smooth sliding of the support plate 22 along the surface of the support rods 31, and the surfaces of the other two support rods 31 are slidably connected to the inner side of the other support plate 22.
[0021] It is worth noting that both ends of the four expansion springs 32 are connected to the top of one of the support plates 22 and the inner wall of the feed cylinder 5, which facilitates the improvement of the stability of the expansion springs 32.
[0022] It is worth noting that both ends of the two contraction springs 33 are connected to the bottom end of another support plate 22 and the inner wall of the feed cylinder 5, which facilitates the reliable fixing of the contraction springs 33 and ensures the stable output of the reset force.
[0023] It is worth mentioning that the other side of the feed cylinder 5 is connected to the other side of the collection box 8, and the inner side of the feed cylinder 5 is connected to the inner side of the collection box 8, which makes it easy for the screened impurities to directly enter the collection box 8 and avoid blockage in the intermediate conveying process.
[0024] The screening plate 23 is existing technology and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, back, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.
[0025] Working principle: First, two drive sources 11 are turned on synchronously. The two drive sources 11 drive the two cams 21 to rotate synchronously. At this time, the convex ends of the two rotating cams 21 synchronously drive the two support plates 22 to move upward, thereby causing the screening plate 23 to be pushed upward. When the convex ends of the cams 21 are rotating and not in contact with the support plates 22, the elastic downward pushing action of the expansion spring 32 and the elastic contraction action of the contraction spring 33 cause the two support plates 22 to be subjected to a downward force, thereby cooperating with the cams 21 to realize the up and down vibration operation of the screening plate 23. After the above preparations are completed, the material to be centrifuged is fed into the feed cylinder 5 through the feed hopper 6. At this time, small particles of material continue to fall without being affected by the screen plate 23 and are fed into the spiral centrifuge body 1 through the feed cylinder 5 and feed pipe 4 for centrifugation. Larger particles of material are intercepted by the vibrating screen plate 23. The inclined and vibrating screen plate 23 screens the large particles of material into the collection box 8 for centralized collection. After the next batch of material has been centrifuged, the discharge valve 10 is opened so that the material can be discharged into the collection box 8 through the discharge pipe 9. The operation is simple and effectively avoids large particles of material from clogging the spiral centrifuge body 1 during centrifugation, which helps to reduce the probability of clogging and improve the centrifugation efficiency.
