Description

Technical Field

[0001] This utility model relates to the field of manufactured sand preparation, specifically to a pretreatment device for manufactured sand. Background Technology

[0002] Pre-treatment of manufactured sand refers to a series of processes performed on it before its use to improve its quality and ensure its suitability for construction projects. The pre-treatment process includes various steps such as screening, washing, crushing, grading, drying, iron removal, storage, quality testing, and environmental protection. Each step has its specific purpose: to improve the quality of the manufactured sand and make it meet the requirements of construction projects.

[0003] Application number CN221361039U discloses a manufactured sand screening device, including a frame, a material box, a soil removal mechanism, and a screening mechanism mounted on the frame. The soil removal mechanism is located below the material box, and the screening mechanism is located at the discharge end of the soil removal mechanism. The soil removal mechanism includes an inclined screen plate, a rotating shaft located at the bottom of the upper end of the inclined screen plate, and a support shaft located at the bottom plate of the lower end of the inclined screen plate. The rotating shaft is rotatably connected to the inclined screen plate, and its two ends are respectively fixed to the frame. The two ends of the support shaft are rotatably connected to the frame, and one end of the support shaft is connected to a drive motor mounted on the frame. Two symmetrically arranged protrusions are fixedly mounted on the support shaft. This utility model, by setting up a soil removal mechanism and a screening mechanism, meets the process requirements for producing manufactured sand from rock tailings. Furthermore, the screening mechanism is located at the discharge end of the soil removal mechanism, allowing the rock tailings after soil and impurity removal to directly enter the screening mechanism for preliminary screening. The device is rationally arranged, convenient to use, and occupies a small area.

[0004] Existing technologies include a material bin, a soil removal mechanism, and a screening mechanism, which together form a screening device to screen materials. The soil removal mechanism is located below the material bin and is connected to the inclined screen plate by a rotating shaft to screen materials by volume. The materials are then removed through the discharge end. However, during the use of the screening device, the rotating shaft drives the inclined screen plate to screen, which can easily damage the shaft and prevent efficient screening, thus affecting the screening efficiency. The fixed position of the discharge end makes it impossible to connect the discharge port to storage structures of different specifications, thereby limiting the use of the screening device. Utility Model Content

[0005] The purpose of this invention is to provide a pre-treatment device for manufactured sand, which solves the problems of inefficient screening and the inability to adjust the discharge port that limit the use of existing pre-treatment devices.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a pre-treatment device for manufactured sand, comprising a support structure. The support structure includes a base with rollers installed at the bottom. Support columns are provided around the top of the base, with grooves inside each column. A support plate and a push rod are installed at the top of each column.

[0008] An adjustable collection box is provided, with telescopic springs connected to both sides of the bottom of the collection box. These springs, along with sliders on both sides, allow for free adjustment of the height at both ends of the collection box. This makes the collection box suitable for discharging materials from storage devices of different sizes and heights, thereby expanding the overall application range of the equipment.

[0009] Furthermore, rollers are fixedly installed around the bottom of the base, the center of the top of the base is fixedly connected to the bottom surface of the support column, the support column has a sliding groove inside, a support plate is fixedly installed on the top of the support column, the two outer sides of the support plate are fixedly connected to push rods, and the two sides of the top of the base are movably connected to the telescopic springs in the storage structure.

[0010] Furthermore, each telescopic spring is equipped with a telescopic rod, the bottom of which is fixedly connected to the top two sides of the base, and the bottom two sides of the telescopic spring are fixedly connected to the bottom of the collection box.

[0011] Furthermore, sliders are symmetrically fixedly installed on both sides of the collection box, the sliders are slidably connected to the inner wall of the chute, and the top of the support column is connected to the frame in the screening assembly.

[0012] Furthermore, the screening assembly includes a connecting column, the top of which is fixedly connected to the bottom of the frame, and movable grooves are provided on both sides inside the frame. The movable grooves are movably connected to movable blocks, and the bottom of the movable blocks is fixedly connected to connecting seats.

[0013] Furthermore, a fixing frame is fixedly connected to one side of the sieve disc, and several sets of through holes are opened on the outside of the sieve disc, with the through holes evenly penetrating the bottom of the sieve disc.

[0014] A drive belt, in conjunction with a motor, rotates the driving pulley. The belt then transmits power to the driven pulley, causing the connected screen disc to move horizontally for screening. This process minimizes the risk of damage to components, thereby improving screening efficiency.

[0015] Furthermore, the fixed frame is movably sleeved with the transmission belt, the transmission belt is electrically connected to the motor at the top, and the transmission belt is located at the top of the support plate.

[0016] This utility model has the following beneficial effects:

[0017] This utility model features an adjustable collection box with telescopic springs connected to both sides of the bottom. These springs, along with sliders on both sides, allow for free adjustment of the height at both ends of the collection box. This enables the collection box to be used for discharging materials from storage devices of different heights, thereby expanding the overall application range of the equipment.

[0018] This invention utilizes a transmission belt in conjunction with a motor to drive the driving wheel, which then transmits power to the driven wheel. This causes the connected screen disc to move horizontally for screening. This process minimizes the risk of damage to the components, thereby improving screening efficiency.

The storage structure 2 includes telescopic springs 201, with a collection box 202 installed on the top of the telescopic springs 201. Slider blocks 203 are installed on both sides of the collection box 202. A screening assembly 3 is installed on the top of the support columns 103. The screening assembly 3 includes a connecting column 301, with a frame 302 on the top of the connecting column 301. A screen plate 303 is connected inside the frame 302. A fixing frame 304 is provided on one side of the screen plate 303. A connecting seat 305 is provided at the bottom of the screen plate 303. A moving block 306 is installed on the outer side of the connecting seat 305.

[0030] An adjustable collection box 202 is provided. The bottom of the collection box 202 is connected to two sides by telescopic springs 201, which, together with the sliders 203 on both sides, allow the height of the two ends of the collection box 202 to be freely adjusted. This makes the collection box 202 suitable for discharging materials from storage devices of different sizes and heights, thereby expanding the overall application range of the equipment.

[0031] The base 101 is fixedly equipped with rollers 102 around its bottom. The rollers 102 on the bottom of the base 101 make the equipment easy to move and fix, adapt to different working environments, and improve the flexibility and applicability of the equipment. The top center of the base 101 is fixedly connected to the bottom surface of the support column 103. The support column 103 has a sliding groove 104 inside. The support plate 105 is fixedly installed on the top of the support column 103. The two outer sides of the support plate 105 are fixedly connected to the push rod 106. The top two sides of the base 101 are movably connected to the telescopic spring 201 in the storage structure 2.

[0032] Each telescopic spring 201 has a telescopic rod installed inside. The bottom of the telescopic rod is fixedly connected to the top two sides of the base 101, and the bottom two sides of the telescopic spring 201 are fixedly connected to the bottom of the collection box 202.

[0033] Slider 203 is symmetrically fixedly installed on both sides of the collection box 202. The slider 203 is slidably connected to the inner wall of the chute 104. The top of the support column 103 is connected to the frame 302 in the screening assembly 3.

[0034] The screening component 3 includes a connecting column 301, the top of which is fixedly connected to the bottom of the frame 302. The frame 302 has movable grooves on both sides inside, and the movable grooves are movably connected to the movable blocks 306. The bottom of the movable blocks 306 is fixedly connected to the connecting seats 305, and the connecting seats 305 are evenly distributed on the bottom of the screen plate 303.

[0035] A fixing frame 304 is fixedly connected to one side of the sieve plate 303. Several sets of through holes are opened on the outside of the sieve plate 303, and the through holes evenly penetrate the bottom of the sieve plate 303.

[0036] A transmission belt 4, in conjunction with a motor 5, drives the drive wheel to rotate. The transmission belt 4 transmits power to the driven wheel, causing the connected screen disc 303 to move horizontally for screening. This process minimizes the risk of damage to components, thereby improving screening efficiency.

[0037] The fixed frame 304 is movably sleeved with the transmission belt 4, which is electrically connected to the motor 5 at the top. The transmission belt 4 is located on the top of the support plate 105. The motor 5 drives the screen disc 303 to reciprocate through the transmission belt 4. This motion ensures that the manufactured sand is evenly distributed on the screen disc 303, avoiding accumulation and further improving screening efficiency. The through-hole design of the screen disc 303 ensures that the manufactured sand is efficiently screened according to particle size, avoiding local accumulation and ensuring that the screened manufactured sand can be discharged evenly, improving product quality. The screening process driven by the motor 5 realizes automated operation, reduces manual intervention, and lowers the difficulty and labor intensity of operation.

[0038] Working Principle: During use, the equipment is moved to the working position using rollers 102 to ensure the base 101 is stable. The motor 5 is then started, and the equipment begins operation. The manufactured sand is poured into the screen 303. The motor 5 drives the fixed frame 304 and the screen 303 to reciprocate via the transmission belt 4, improving screening efficiency. The through holes at the bottom of the screen 303 screen the manufactured sand according to particle size. The through-hole design of the screen 303 ensures efficient screening of the manufactured sand according to particle size. The screened manufactured sand falls into the collection box 202 through the screen 303. The collection box 202 slides within the chute 104 via sliders 203. The height and tilt angle of the two ends of the collection box 202 can be adjusted according to actual needs to facilitate material discharge and ensure the stability of the collection box 202. The manufactured sand pretreatment equipment, through the coordinated work of the support, storage, and screening components 3, combined with the motor 5 drive and the transmission belt 4 design, achieves efficient and stable screening of manufactured sand.
