Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to a bucket elevator mechanism for a cooling tower. Background Technology

[0002] The NE-type plate chain bucket elevator is one of the most widely used vertical lifting equipment. It is suitable for the vertical conveying of medium and large-sized and abrasive materials (such as limestone, cement clinker, gypsum, and lump coal) with a material temperature below 250℃.

[0003] Most existing bucket elevators use bolts to lock and fix the buckets. In actual use, it is necessary to regularly inspect the connection of the buckets. The connection method of fixing with bolts has small stress points and is prone to deformation. In subsequent replacement and maintenance, the operation of disassembling and assembling with bolts is very inconvenient, which leads to a longer maintenance cycle and affects the working efficiency of the equipment. Utility Model Content

[0004] Based on the above description, this utility model provides a bucket elevator mechanism for a cooling tower to solve the shortcomings of existing bucket elevators, which mostly use bolts to fix the buckets, easily leading to deformation at the connection and making subsequent disassembly and assembly very inconvenient, thus affecting the production efficiency of the equipment.

[0005] This utility model is achieved through the following technical solution:

[0006] A bucket elevator mechanism for a cooling tower includes a body with a chain conveyor belt inside. The surface of the chain conveyor belt is provided with several mounting seats, and each mounting seat is provided with a hopper. The end of the hopper is inserted into the mounting seat and locked and fixed by a clamping assembly. The top and bottom of the body are respectively provided with a feed inlet and a discharge outlet. The top of the feed inlet extends vertically upward and communicates with a storage tank. The discharge outlet extends obliquely downward and connects to the opening at the top of the cooling tower.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the surface of the chain conveyor belt is arranged with several chain plates at intervals, and each chain plate has a mounting groove at the center of its surface. The mounting base is fixedly installed inside the mounting base by bolts, and its top surface is flush with the surface of the chain plate. The mounting base has a through hole at its center, which extends toward the chain plate and passes through the chain plate.

[0009] Furthermore, the clamping assembly includes an adjustment plate disposed inside the mounting base. The surface of the adjustment plate is provided with a spiral-shaped slot. A rectangular opening is also provided on the inner sidewall of the through hole. A clamping block is movably installed in the rectangular opening. The clamping block extends to the mounting base and has a protrusion at the bottom. The protrusion extends downward and is vertically inserted into the slot.

[0010] Furthermore, the back of the adjusting plate is fixedly connected to the inner wall of the mounting base via a ball bearing, and the mounting base extends to the back of the chain plate to form a rectangular protrusion. An adjusting end is provided at the center of the back of the adjusting plate. The adjusting end passes through the ball bearing and extends into the rectangular protrusion. A worm gear is fitted on the outer wall of the adjusting end. A worm is arranged longitudinally inside the rectangular protrusion, and the worm and the worm gear mesh with each other. One end of the worm extends to the outside of the rectangular protrusion and is provided with an adjusting cap.

[0011] Furthermore, the end face of the hopper is provided with a connecting plate, and the center of the connecting plate is provided with a plug shaft. The outer wall of the plug shaft and the inner wall of the through hole are provided with a matching spline structure and are movably connected.

[0012] Furthermore, the surface of the insert shaft is also provided with a limiting groove. When the insert shaft is inserted directly into the through hole at the center of the mounting base, the clamping block abuts against the inside of the limiting groove.

[0013] Furthermore, the surface of the clamping block is also provided with an elastic layer.

[0014] Furthermore, the machine body is also equipped with a recycling hopper, which is located directly below the chain conveyor, and a valve is provided at the outlet at the bottom of the recycling hopper.

[0015] Furthermore, a storage box is provided below the recycling hopper, and an opening is provided on the bottom surface of the machine body. The opening extends inward and forms a groove on the inner side wall of the machine body. The storage box is slidably inserted into the machine body along the direction of the groove, and a handle is provided on the outward side of the storage box.

[0016] Furthermore, the bottom of the machine body is also provided with a shock-absorbing base, and the top of the shock-absorbing base is provided with a spring damper and is fixedly connected to the bottom surface of the machine body.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0018] This application improves upon the existing hoist by adopting a detachable installation structure instead of a bolted structure, which allows workers to replace or maintain the buckets. Moreover, this structure uses a plug-in fixing structure, in which the plug shaft on the back of the bucket is directly plugged into the conveyor and then locked with a clamping component. This not only increases the force-bearing area, thereby enhancing the stability of the connection between the two, but also makes it easier for workers to disassemble and assemble, making it more convenient to use.

Detailed Implementation

[0027] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0029] Combination Figure 1-7 As shown, a bucket elevator mechanism for a cooling tower includes:

[0030] The body 1 is a rectangular metal box with a feed inlet 11 and a discharge outlet 12 at the top and bottom, respectively. The feed inlet 11 corresponds to and is connected to the bottom opening of the storage box, while the discharge outlet 12 corresponds to and is connected to the top opening of the cooling tower, so as to transport the material from the lower position to the higher position.

[0031] The chain plate conveyor belt 2 is an existing chain plate type conveyor, which is fixedly installed inside the machine body 1, and a mounting seat 3 is provided on each chain plate;

[0032] The hopper 4 is used to cooperate with the chain conveyor belt 2 for vertical conveying, and its end is fixedly connected to the chain plate through the mounting base 3;

[0033] The clamping component 5 is located inside the mounting base 3 to enhance the connection strength between the hopper 4 and the chain plate, and at the same time replaces the existing bolt fixing structure, making it a detachable mounting structure.

[0034] Specifically, in this embodiment, each chain plate on the chain conveyor belt 2 has a mounting groove at its center, through which the chain plate passes and a stepped surface is formed on the inner wall of the mounting groove.

[0035] Mounting seat 3 is perfectly embedded inside the mounting groove, with its top surface flush with the surface of the chain plate. Meanwhile, the four sides of mounting seat 3 are attached to the step surface and secured with bolts. A through hole is also provided in the center of mounting seat 3, and the through hole should be concentric with the mounting groove.

[0036] The end face of the hopper 4 is provided with a connecting plate 41. A shaft 42 is formed by protrusion at the center of the connecting plate 41. The shaft 42 extends along the through hole at the center of the mounting groove and is inserted into the inside. The inner wall and the outer wall of the shaft 42 are combined by a spline structure.

[0037] The clamping assembly 5 includes an adjusting plate 51 and clamping blocks 52. The mounting base 3 is hollow inside. The adjusting plate 51 is rotatably mounted on its inner bottom surface via ball bearings. The adjusting plate 51 has an annular structure with a spiral-shaped slot on its top surface. Rectangular openings are also provided on the inner wall of the through hole of the mounting base 3. At least three rectangular openings are provided, arranged in a circumferential array. A clamping block 52 is sequentially placed inside each rectangular opening. The clamping block 52 extends partially into the mounting base 3 and has a protrusion on its bottom surface. The protrusion extends downwards and can be inserted into the slot, forming a simple three-jaw chuck structure. The arc-shaped inner wall of the slot drives the protrusion, causing all three clamping blocks to move along the direction of the rectangular openings. For example… Figure 4 As shown.

[0038] The surface of the clamping block should also be reinforced with an elastic layer, i.e., a structure of soft materials such as rubber pads, to act as a cushioning material.

[0039] In this embodiment, to further improve the clamping effect, a limiting slot should be additionally arranged on the outer side wall of the insert shaft 42. When the insert shaft 42 is inserted into the through hole, the adjusting plate can drive the clamping block to insert it into the limiting slot, thereby locking and fixing it and improving the connection strength between the two. When disassembling it, it is only necessary to twist the adjusting plate in the opposite direction. This ensures the reliability of the connection and simplifies the installation steps, making it more convenient to operate during subsequent regular maintenance.

[0040] In the mounting base 3, a rectangular protrusion is provided on its back side and extends to the back side of the chain plate. An adjustment end 53 is provided at the center of the back side of the adjustment plate 51. The adjustment end 53 passes through the central hole of the ball bearing and extends into the interior of the rectangular protrusion. A worm wheel 54 is also fitted on the outer wall of the adjustment end 53. A worm 55 is arranged longitudinally inside the rectangular protrusion. The worm 55 is engaged with the worm wheel 54. One end of the worm 55 extends to the outside and is provided with an adjustment cap 56. The worm wheel 54 and the worm 55 have a self-locking function. That is, the clamping component 5 can be fixed or released by twisting the adjustment cap 56. After the adjustment is completed, since the worm wheel 54 cannot drive the worm 55 to rotate in the opposite direction, it can be ensured that the adjustment plate will not rotate in the opposite direction due to vibration and the reaction force of clamping, thus ensuring the stability of its installation structure.

[0041] Inside the machine body 1, there is also a recycling hopper 6. In actual use, whether it is during the feeding or discharging process, some materials will fall to the bottom of the machine body 1. In order to facilitate their recycling, the recycling hopper 6 should be set below the chain conveyor belt 2 to concentrate the materials during the feeding and discharging process.

[0042] An opening is provided on the bottom side wall of the machine body 1. The opening extends inward and forms a groove on the inner wall of the machine body 1. A storage box 7 is installed inside the groove. The storage box 7 can slide along the groove into the machine body 1 to collect the material collected by the recycling hopper 6. The material is periodically removed for processing using this pull-out structure. This structure allows workers to clean the material accumulated at the bottom without removing the side panel, greatly improving the convenience of cleaning.

[0043] In addition, to facilitate the removal of the storage box 7 by staff without stopping the machine, a valve should be installed at the outlet at the bottom of the recycling hopper 6. This valve can be a MAC solenoid valve, which means that the valve can be manually controlled to discharge material each time, and then the storage box 7 can be taken out directly. Furthermore, to further improve convenience, a handle 71 can be installed at the center of the outer end face of the storage box 7.

[0044] During operation, the entire equipment will generally vibrate. Therefore, a shock-absorbing base 8 is fixedly connected to its bottom to block the transmission of vibration. The top surface of the base is provided with a guide groove, and a spring damper is vertically installed in the guide groove. The bottom of the machine body 1 is vertically inserted into the guide groove, and its bottom surface is fixedly connected to the spring damper. In this way, the spring damper absorbs the vibration, reduces the vibration frequency of the entire machine body 1, and improves the stability of the equipment operation.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this utility model.
