Description

Technical Field

[0001] This utility model relates to the field of fabric spreading devices, and more specifically, to a new uniform fabric spreading device with feeding and receiving functions. Background Technology

[0002] Most wastewater treatment plants in China use high-pressure belt filter presses to treat sludge with low water content. High-pressure belt filter presses rely on filter screens to filter sludge. Due to the characteristics of sludge, the dewatering process is relatively difficult. The dewatering process mainly relies on the high pressure of rollers to squeeze the sludge and make the filtrate pass through the filter belt, which requires the design of new material feeding devices.

[0003] A search revealed that Chinese Patent Publication No. CN111646249A discloses "A Fabric Spreading Device and Method for a Belt Conveyor," comprising: a support device with adjustable height; a spreader including a rotating shaft and bidirectional helical blades, the rotating shaft being rotatably connected to the support device, the bidirectional helical blades being sleeved on the rotating shaft, and the blade pitch of the bidirectional helical blades being variable; and a drive device connected to the support device, the drive device driving the rotating shaft to rotate, spreading the fabric evenly to both sides of the conveyor belt through the rotating bidirectional helical blades, thus achieving even fabric spreading; and reducing belt wear and maintenance / replacement costs; simultaneously, by adjusting the height between the bidirectional helical blades and the conveyor belt through the support device, the thickness of the spread fabric can be adjusted as needed, but the following drawbacks still exist:

[0004] (1) The existing fabric structure of the fabric device requires the incoming material to fall on the center line. If it is biased to one side, it will result in more material on one side and less material on the other, or even no material on one side, causing uneven fabric distribution.

[0005] (2) After a long period of operation, the surface of the material distribution spiral of the existing fabric device will be covered with a large amount of sludge, which will cause blockage of the fabric components. The existing material distribution spiral can only be rinsed with external water, which has a blind spot and affects the thoroughness of cleaning.

[0006] Therefore, we have made improvements to this and proposed a new uniform material distribution device with feeding and receiving functions. Utility Model Content

[0007] The purpose of this invention is to address the issue that the existing fabric feeding device requires the incoming material to fall on the center line. If it is biased to one side, it will result in one side having more material than the other, or even no material at all, causing uneven fabric distribution. Furthermore, the existing fabric feeding device's distributing spiral will accumulate a large amount of sludge on its surface after long-term operation, which will cause blockage of the fabric components. The existing distributing spiral can only be rinsed with external water, which creates a blind spot in the rinsing process.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] A new uniform material distribution device with feeding and receiving functions is proposed to improve the above-mentioned problems.

[0010] The present invention is as follows:

[0011] The structure includes a steel frame, inside which a fabric assembly is installed, and at both ends of the fabric assembly are mating components.

[0012] The fabric assembly includes a feed hopper installed at the upper front end of a steel frame, and a feed auger is fitted between the steel frames at the lower side of the feed hopper.

[0013] The docking assembly includes end plates disposed on the inner walls of both sides of the steel frame. An inner groove is formed inside the center of the end plate. A first bevel gear is disposed on the inner wall of the upper end of the inner groove. A knob is connected to the upper end of the first bevel gear.

[0014] As a preferred technical solution of this utility model, the right end of the feeding screw is connected to a connecting roller through the steel frame, the center of the steel frame is provided with a main distributing screw, the right end of the main distributing screw is connected to a drive roller through the steel frame, the drive roller and the connecting roller are fitted with a transmission belt, and the left end of the main distributing screw is connected to a first motor through the steel frame.

[0015] As a preferred technical solution of this utility model, an auxiliary distributing screw is installed between the steel frames at the rear side of the main distributing screw, and a round steel is fitted around the center of the auxiliary distributing screw. A second motor is connected to the left end of the auxiliary distributing screw through the steel frame.

[0016] As a preferred technical solution of this utility model, the inner wall of the inner groove is provided with a second conical gear that cooperates with the first conical gear.

[0017] As a preferred technical solution of this utility model, an expansion groove is opened on the outer side of the inner groove near the main or auxiliary dispensing screw, a screw is provided inside the expansion groove, and a retaining post is fitted on the outer wall of the screw.

[0018] As a preferred technical solution of this utility model, the main dispensing screw and the auxiliary dispensing screw have slots on their side walls at both ends that cooperate with the locking posts.

[0019] As a preferred technical solution of this utility model, the side wall of the telescopic groove is provided with a limiting groove, and the side wall of the locking post is provided with a limiting block that cooperates with the limiting groove.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] In the solution of this utility model:

[0022] 1. The system consists of a feed hopper, a feed screw, a main distribution screw, and an auxiliary distribution screw. During operation, the first motor drives the main distribution screw to rotate, which in turn drives the drive roller connected to the right end to rotate. This, in turn, drives the connecting roller via a transmission belt, which in turn drives the feed screw connected to the connecting roller to rotate synchronously. During operation, material is fed into the feed hopper via a conveyor and accumulates on the filter belt. The feed screw actively gathers the material to the center position. As the filter belt moves, the material is carried to the main distribution screw. The main distribution screw, driven by the first motor, evenly spreads the sludge material from the center to both sides. When the material accumulates on both sides, the auxiliary distribution screw, driven by the second motor, conveys the material from both sides to the center for a secondary spreading, ensuring even distribution. When the material level is too high, the round steel in the middle of the auxiliary feeding auger will push the material back to the main feeding auger and re-lay it together with the newly fed material. This structure prevents problems such as uneven distribution and uneven thickness by repeatedly laying the material. The height of both the main and auxiliary feeding augers can be adjusted via the steel frame. Both the first and second motors support speed adjustment to adapt to different processing volumes and different properties of sludge materials. Compared with the original feeding device, the problem of feed drop point drift is completely solved, eliminating the need for frequent manual inspections and adjustments when deviations are detected. It is highly adaptable to various feeding and conveying equipment, has low requirements for feed drop point, ensures uniform distribution, requires no manual intervention, and the equipment can work reliably and continuously.

[0023] 2. By setting up a first bevel gear, a second bevel gear, a screw, a locking pin, and a limiting block, when it is necessary to thoroughly clean the sludge adhering to the surface of the main and auxiliary distributing screws, turning the knob drives the first bevel gear connected to it to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the screw connected to it to rotate. The locking pin, under the limitation of the limiting block embedded in the limiting groove, slides into the telescopic groove. When the locking pin completely disengages from the locking grooves opened at both ends of the main or auxiliary distributing screw, the main or auxiliary distributing screw can be directly disassembled separately for thorough cleaning, avoiding blockage in the subsequent material distribution process and improving the practicality of the material distribution device.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0032] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] like Figure 1-5 As shown, this embodiment proposes a new uniform material distribution device with feeding and receiving functions, including a steel frame 1, a material distribution component is provided inside the steel frame 1, and docking components are provided at both ends of the material distribution component.

[0036] The fabric assembly includes a feed hopper 201 installed at the upper front end of the steel frame 1, and a feed screw 202 installed between the steel frames 1 at the lower side of the feed hopper 201.

[0037] The docking assembly includes end plates 301 set on the inner walls of both sides of the steel frame 1. An inner groove 302 is opened in the center of the end plate 301. A first bevel gear 303 is set on the inner wall of the upper end of the inner groove 302. A knob 304 is connected to the upper end of the first bevel gear 303.

[0038] like Figure 2 As shown, the right end of the feeding screw 202 passes through the steel frame 1 and is connected to the connecting roller 203. The main distributing screw 206 is set at the center of the steel frame 1. The right end of the main distributing screw 206 passes through the steel frame 1 and is connected to the drive roller 204. The drive roller 204 and the connecting roller 203 are fitted with a transmission belt 205. The left end of the main distributing screw 206 passes through the steel frame 1 and is connected to the first motor 207. When operating, the first motor 207 drives the main distributing screw 206 to rotate, which drives the drive roller 204 connected to the right end to rotate. Through the transmission belt 205, the connecting roller 203 is driven to rotate, which in turn drives the feeding screw 202 connected to the connecting roller 203 to rotate synchronously.

[0039] like Figure 2 As shown, an auxiliary material distribution screw 208 is installed between the steel frame 1 at the rear of the main material distribution screw 206 and the auxiliary material distribution screw 208. A round steel 209 is fitted around the center of the auxiliary material distribution screw 208. The left end of the auxiliary material distribution screw 208 passes through the steel frame 1 and is connected to a second motor 210. When the material in the middle is too high, the round steel 209 in the middle of the auxiliary material distribution screw 208 will push the material back to the main material distribution screw 206 and re-lay it together with the newly fed material. This structure prevents uneven material distribution by repeatedly laying the material.

[0040] like Figure 4 As shown, the inner wall of the inner groove 302 is provided with a second bevel gear 305 that cooperates with the first bevel gear 303. When it is necessary to thoroughly clean the sludge adhering to the surface of the main feeding screw 206 and the auxiliary feeding screw 208, the knob 304 is turned to drive the first bevel gear 303 connected to it to rotate, and the meshing drives the second bevel gear 305 to rotate.

[0041] like Figure 4As shown, an expansion groove 306 is opened on the outer side of one end of the inner groove 302 near the main distributing screw 206 or the auxiliary distributing screw 208. A screw 307 is provided inside the expansion groove 306. A locking pin 308 is fitted on the outer wall of the screw 307. When the screw 307 rotates, it engages and drives the locking pin 308 to slide into the expansion groove 306 under the limitation of the limiting block 311 embedded in the limiting groove 310. When the locking pin 308 completely disengages from the locking grooves 309 opened at both ends of the main distributing screw 206 or the auxiliary distributing screw 208, the main distributing screw 206 or the auxiliary distributing screw 208 can be directly disassembled separately.

[0042] like Figure 4 As shown, the main distributing spiral 206 and the auxiliary distributing spiral 208 have slots 309 on their side walls at both ends that cooperate with the locking posts 308. The locking posts 308 can be completely disengaged from the slots 309 at both ends of the main distributing spiral 206 or the auxiliary distributing spiral 208, so that the main distributing spiral 206 or the auxiliary distributing spiral 208 can be directly disassembled for thorough cleaning.

[0043] like Figure 4 As shown, the side wall of the telescopic groove 306 has a limiting groove 310, and the side wall of the locking post 308 is provided with a limiting block 311 that cooperates with the limiting groove 310. When the screw 307 rotates, it engages and drives the locking post 308 to slide into the telescopic groove 306 under the limiting block 311 embedded in the limiting groove 310. When the locking post 308 completely disengages from the locking grooves 309 opened at both ends of the main material distributing screw 206 or the auxiliary material distributing screw 208, the main material distributing screw 206 or the auxiliary material distributing screw 208 can be directly disassembled separately for thorough cleaning and to avoid blockage in the subsequent material distribution process.

[0044] Specifically, in operation, this feeding device works as follows: The first motor 207 drives the main distributing screw 206 to rotate, which in turn drives the drive roller 204 connected to the right end to rotate. This, in turn, drives the connecting roller 203 to rotate via the transmission belt 205, which in turn drives the feeding screw 202 connected to the connecting roller 203 to rotate synchronously. During operation, the material is fed into the feeding hopper 201 via the conveying equipment and accumulates on the filter belt. The feeding screw 202 actively gathers the material to the middle position. As the filter belt moves, the material is carried to the main distributing screw 206. The main distributing screw 206, through the first motor 207, distributes the sludge... The material is evenly laid from the center outwards. When the material accumulates on both sides, the auxiliary distributing screw 208, via the second motor 210, conveys the material from both sides back to the center for secondary laying, ensuring even distribution. When the material in the center is too high, the round steel 209 in the center of the auxiliary distributing screw 208 will push the material back to the main distributing screw 206, where it will be re-laid along with newly arrived material. This structure prevents uneven distribution and thickness by repeatedly laying the material. The height of both the main distributing screw 206 and the auxiliary distributing screw 208 can be adjusted via the steel frame 1. Both the main feed screw 207 and the second motor 210 support speed adjustment to adapt to different processing volumes and sludge materials of different properties. Compared with the original feeding device, it completely solves the problem of feed drop point drift, eliminating the need for frequent manual inspections and adjustments when deviations are detected. It is highly adaptable to various feeding and conveying equipment, with low requirements for feed drop point, ensuring uniform feeding. No manual intervention is required, and the equipment can operate reliably and continuously. When it is necessary to thoroughly clean the sludge adhering to the surfaces of the main feed screw 206 and the auxiliary feed screw 208, turning the knob 304 drives the first feed screw connected to it. The rotation of the bevel gear 303 meshes with and drives the rotation of the second bevel gear 305, which in turn drives the screw 307 connected to it to rotate. This meshing causes the locking pin 308 to slide into the telescopic groove 306 under the limiting block 311's position within the limiting groove 310. When the locking pin 308 completely disengages from the locking grooves 309 at both ends of the main material distributing screw 206 or the auxiliary material distributing screw 208, the main material distributing screw 206 or the auxiliary material distributing screw 208 can be directly disassembled separately for thorough cleaning, preventing blockages in the subsequent material distribution process and improving the practicality of the material distribution device.

[0045] All technical features in this embodiment can be freely combined according to actual needs.

[0046] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
