Description

Technical Field

[0001] This utility model relates to a field of application, and in particular to a sieving device for processing composite bentonite. Background Technology

[0002] Composite bentonite is a new type of bentonite product made by modifying natural bentonite through physical, chemical, or mechanical methods and combining it with other functional materials, such as polymers, inorganic minerals, and additives. Its purpose is to optimize the performance of natural bentonite and expand its application range. The main component of natural bentonite is montmorillonite, which has properties such as adsorption and expansion. However, its single properties are often insufficient to meet the needs of complex scenarios. Composite bentonite can achieve performance superposition or enhancement through composite modification. During the preparation process of composite bentonite, such as mixing, grinding, and modification, particle agglomeration or uneven particle size may occur. It is necessary to remove coarse particles or lumps by sieving to make the particle size distribution of the product more uniform and ensure its stable performance in application.

[0003] However, during the sieving process of bentonite, bentonite particles may clog the sieve holes, resulting in low sieving efficiency. Furthermore, it is not convenient to classify and screen bentonite of different particle sizes during sieving, nor is it convenient to collect or use bentonite of different particle sizes separately.

[0004] Therefore, we propose a sieving device for processing composite bentonite. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a screening device for processing composite bentonite. Through the synergistic action of the drive component, the shaking component, and the anti-bumping component, the screening components can form a composite motion combining horizontal shaking and vertical bumping, causing the material to frequently tumble and collide on the screen, effectively avoiding screen hole clogging and significantly improving screening efficiency. Multiple sets of vertically distributed screening components can achieve graded screening, allowing materials of different particle sizes to be separated step by step. In addition, the guide troughs of the upper and lower screening components are in opposite positions, ensuring the reasonable flow and graded collection of materials of different particle sizes in multi-stage screening, thereby improving material utilization.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A sieving device for processing composite bentonite includes a drive assembly. A swaying assembly is slidably connected to the top of the drive assembly. Multiple sets of anti-slip components, arranged vertically, are fixedly connected to the top of the swaying assembly. Each set of anti-slip components has a sieving component at its top, and the bottom of the upper anti-slip component is detachably connected to the lower sieving component. Each set of anti-slip components consists of four symmetrically distributed anti-slip components. The drive assembly includes a base. Two symmetrical slide rails are fixedly connected to the top of the base. A support block is fixedly connected to the top of the base and to the left of the slide rails. A shaft is rotatably connected to the upper end of the support block. A wheel is fixedly connected to the front end of the shaft. A rotating shaft is eccentrically connected to the front end of the wheel. A linkage rod is rotatably connected to the front end of the rotating shaft. The swaying assembly includes a collection frame. Multiple sliders, slidably connected to the slide rails, are fixedly connected to the bottom of the collection frame. Multiple connecting blocks, rotatably connected to the linkage rod, are fixedly connected to the left end of the collection frame.

[0008] Furthermore, a fixing block is fixedly connected to the top of the base and to the left of the support block, a motor is fixedly connected to the top of the fixing block, a first pulley is fixedly connected to the transmission end of the motor, and a belt is drivenly connected to the outer wall of the first pulley.

[0009] Furthermore, a second pulley connected to a belt drive is fixedly connected to the rear end of the shaft.

[0010] Furthermore, the anti-bump assembly includes a connecting plate, a spring is fixedly connected to the top of the connecting plate, and a mounting block is fixedly connected to the top of the spring.

[0011] Furthermore, the sieving assembly includes a sieving frame, and mounting pieces corresponding to the mounting blocks are fixedly connected to the upper and lower ends and all four sides of the sieving frame.

[0012] Furthermore, a guide trough is fixedly connected to the right end of the sieve frame, and one side of the guide trough and the end away from the sieve mesh tapers inward.

[0013] Furthermore, a screen is fixedly connected inside the sieve frame and at the left end of the guide trough, and the end of the screen near the guide trough is inclined downward.

[0014] Furthermore, the position of the guide chute of the sieve assembly described above is opposite to the position of the guide chute of the sieve assembly described below.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. Through the cooperation of the drive component, the shaking component and the anti-bumping component, the screening component forms a compound motion of horizontal shaking and vertical bumping, which causes the material to frequently turn over and collide on the screen, effectively avoiding screen hole blockage, significantly improving screening efficiency, and ensuring full screening of bentonite material.

[0017] 2. Bentonite can be graded and screened by multiple sets of screen components distributed vertically. Materials of different particle sizes are separated step by step through screen components of different specifications. The upper anti-bumping component and the lower screen component are detachably connected, which facilitates the individual maintenance, replacement or adjustment of the specifications of the screen components according to the screening requirements, and improves the practicality and flexibility of the device.

[0018] 3. The inclined screen inside the sieve frame uses gravity to guide the material to flow into the guide trough, reducing material retention and accumulation. The constriction port design of the guide trough concentrates the screened material and discharges it, preventing it from scattering and facilitating subsequent collection and processing. At the same time, the guide troughs of the upper and lower sieve components are in opposite positions, ensuring that materials of different particle sizes flow reasonably and are collected in stages during multi-stage screening, thereby improving material utilization.

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0027] Reference Figures 1 to 5 As shown, a sieving device for processing composite bentonite is provided in a preferred embodiment of the present invention. It includes a drive component 1, a slidably connected swaying component 2 at the top of the drive component 1, and multiple sets of anti-bumping components 3 fixedly connected to the top of the swaying component 2 and arranged vertically. Each set of anti-bumping components 3 is provided with a sieving component 4 at the top, and the bottom end of the upper anti-bumping component 3 is detachably connected to the lower sieving component 4. The number of anti-bumping components 3 in each set is four and they are symmetrically distributed.

[0028] A multi-stage linkage screening system is constructed through the hierarchical connection of drive component 1, shaking component 2, anti-bumping component 3, and screening component 4. Multiple sets of vertically distributed screening components 4 can realize the graded screening of bentonite, allowing materials of different particle sizes to be separated step by step through screening components 4 of different specifications. Four symmetrically distributed anti-bumping components 3 ensure balanced force during screening, simulate a bumpy environment, and improve the screening efficiency of screening components 4. The detachable connection design facilitates the individual maintenance, replacement, or adjustment of the specifications of screening components 4 according to screening needs, improving the practicality and flexibility of the device.

[0029] The drive assembly 1 includes a base 101, with two symmetrical slide rails 102 fixedly connected to the top of the base 101. A support block 106 is fixedly connected to the top of the base 101 and to the left of the slide rails 102. A shaft 107 is rotatably connected to the upper end of the support block 106. A wheel 112 is fixedly connected to the front end of the shaft 107. A rotating shaft 110 is eccentrically connected to the front end of the wheel 112. A linkage rod 111 is rotatably connected to the front end of the rotating shaft 110. The shaking assembly 2 includes a collection frame 201, with multiple sliders 202 fixedly connected to the bottom of the collection frame 201 and slidably connected to the slide rails 102. Multiple connecting blocks 203 are fixedly connected to the left end of the collection frame 201 and rotatably connected to the linkage rod 111.

[0030] The base 101 provides a stable support foundation for the device. The symmetrically arranged slide rails 102 cooperate with the slider 202 to limit the movement trajectory of the shaking component 2, so that it can only slide back and forth in the horizontal direction, ensuring the stability and regularity of the shaking process. The wheel 112, the eccentric rotating shaft 110 and the linkage rod 111 form a crank-connecting rod mechanism. When the wheel 112 rotates with the shaft 107, the eccentric rotating shaft 110 pushes and pulls the connecting block 203 through the linkage rod 111, driving the shaking component 2 to make periodic reciprocating motion along the slide rails 102. This provides continuous horizontal shaking power for the anti-bumping component 3 and the screening component 4 above, causing the material to be evenly dispersed and continuously moved on the screen 404, creating conditions for efficient screening.

[0031] A fixing block 103 is fixedly connected to the top of the base 101 and to the left of the support block 106. A motor 104 is fixedly connected to the top of the fixing block 103. A first pulley 105 is fixedly connected to the transmission end of the motor 104. A belt 109 is drivenly connected to the outer wall of the first pulley 105. A second pulley 108, which is drivenly connected to the belt 109, is fixedly connected to the rear end of the shaft 107.

[0032] With motor 104 as the power source, the transmission system consisting of first pulley 105, belt 109 and second pulley 108 stably transmits rotational power to shaft 107, driving wheel 112 and crank connecting rod mechanism to operate. It can adapt to the long-term reciprocating shaking working requirements of the screening device and ensure the reliability and efficiency of power transmission.

[0033] The anti-bump assembly 3 includes a connecting plate 301, a spring 302 is fixedly connected to the top of the connecting plate 301, and a mounting block 303 is fixedly connected to the top of the spring 302.

[0034] Fixed to the shaking assembly 2 by the connecting plate 301, it moves horizontally synchronously with the shaking assembly 2. The spring 302 converts the horizontal shaking into up-and-down swaying motion through elastic deformation. When the shaking assembly 2 slides back and forth, the spring 302 periodically extends and retracts due to inertia and the gravity of the material, which drives the mounting block 303 and the screening assembly 4 above to vibrate up and down, forming a compound motion of horizontal shaking + vertical swaying. This allows the material to be frequently turned over and impacted, effectively preventing the screen holes from clogging.

[0035] The sieving assembly 4 includes a sieving frame 401, and mounting pieces 402 corresponding to the mounting blocks 303 are fixedly connected to the upper and lower ends and all four sides of the sieving frame 401.

[0036] The mounting plate 402 and the mounting block 303 of the anti-bump component 3 are connected by bolts or other fasteners, so that the sieve frame 401 and the anti-bump component 3 can be detachably fixed. This makes the replacement of the sieve frame 401 simple and quick, without disassembling the entire device. The sieve frame 401 can be removed separately by simply loosening the connector of the mounting plate 402. This makes it easy to replace the screen 404 with different aperture sizes according to the particle size requirements of bentonite, or to replace the worn screen 404 in a timely manner. This significantly improves the versatility and ease of maintenance of the device. The size of the screen aperture of the screen 404 can be selected according to actual needs, which will not be elaborated here.

[0037] A guide trough 403 is fixedly connected to the right end of the sieve frame 401. One side of the guide trough 403 and the end away from the screen 404 are inwardly contracted. A screen 404 is fixedly connected to the left end of the sieve frame 401 and located in the guide trough 403. The end of the screen 404 near the guide trough 403 is inclined downward.

[0038] The inclined screen 404 uses gravity to guide the material to flow towards the guide trough 403, reducing the retention and accumulation of material on the screen 404 and increasing the effective screening area of ​​the screen 404; the constriction port design of the guide trough 403 can concentrate and discharge the screened material, avoid the material from scattering, and facilitate subsequent collection and processing.

[0039] The position of the guide chute 403 of the upper screening component 4 is opposite to that of the guide chute 403 of the lower screening component 4;

[0040] By reversing the orientation of the upper and lower screening components 4 guide troughs 403, a reasonable flow path for materials during multi-stage screening is ensured. For example, coarse material screened by the upper screen 404 is discharged from the rear guide trough, while fine material screened by the lower screen 404 is discharged from the front guide trough. This allows different materials to be discharged to different locations, ensuring that materials of different particle sizes are separated step by step. This enables the classification and collection of various materials of different coarseness, significantly improving the overall screening accuracy and material utilization rate. The finest material falls into the collection frame 201 after screening.

[0041] Specific implementation process: First, the composite bentonite material to be screened is poured onto the screen 404 of the uppermost screening component 4. Then, the motor 104 is started. The transmission end of the motor 104 drives the first pulley 105 to rotate, and the power is transmitted to the second pulley 108 through the belt 109, which in turn causes the shaft 107 to rotate. The wheel 112 at the front end of the shaft 107 rotates accordingly. During the rotation of the eccentrically positioned rotating shaft 110 at the front end of the wheel 112, the connecting block 203 of the shaking component 2 is pushed and pulled by the linkage rod 111, causing the slider 202 at the bottom of the collection frame 201 to periodically reciprocate on the slide rail 102. The entire swaying assembly 2 reciprocates horizontally, and this reciprocating motion causes the anti-bumping assembly 3 at its top to move horizontally in sync. As the connecting plate 301 of the anti-bumping assembly 3 moves with the swaying assembly 2, the spring 302, due to inertia and the gravity of the screening assembly 4 above and the material, undergoes periodic expansion and contraction deformation. This, in turn, causes the mounting block 303 and the screening assembly 4 to vibrate up and down, resulting in a combined horizontal swaying and vertical bumping motion of the screening assembly 4. This combined motion causes the material inside the screening frame 401 to frequently tumble and collide on the screen 404, effectively preventing screen blockage and improving screening efficiency. In terms of efficiency, the material on the screen 404, due to the downward inclination of the end of the screen 404 near the guide chute 403, flows towards the guide chute 403 under the combined action of gravity and vibration. When the material passes through the screen 404, fine particles smaller than the aperture of the screen 404 pass through the screen 404 and fall into the screening assembly 4 below or directly into the collection frame 201; coarse particles larger than the aperture of the screen 404 continue to move along the surface of the screen 404 towards the guide chute 403 and are discharged through the guide chute 403. Because the position of the guide chute 403 of the upper screening assembly 4 is different from that of the guide chute 403 of the lower screening assembly 4, the material flows towards the guide chute 403. The material troughs 403 are positioned in opposite directions. For example, the guide trough 403 of the upper screening component 4 is located on the right side, while the guide trough 403 of the lower screening component 4 is located on the left side. In this way, the coarse material screened by the upper screen 404 will be discharged from the guide trough on the right side, while the material screened by the lower screen 404 will be discharged from the guide trough on the left side. This ensures that materials of different particle sizes can be discharged separately along the guide troughs 403 in opposite directions during the multi-stage screening process, realizing the graded collection of various coarse and fine materials. The finest material, after being screened by multiple screens 404, finally falls into the collection frame 201, completing the entire screening process of the composite bentonite.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
