Description

Technical Field

[0001] This utility model relates to the field of sand washing technology, and in particular to a calcium carbonate sand washing device. Background Technology

[0002] Calcium carbonate sand, a widely used basic raw material in the industrial field, requires multiple cleaning processes during its preparation to remove surface impurities. Traditional sand washing equipment generally adopts a combination of high-pressure water washing and vibrating screening, but this method has significant technical defects in practical applications: Firstly, direct washing of untreated blocky sand can easily lead to the inability to effectively remove internal impurities, and conventional stirring mechanisms can only achieve surface rinsing, resulting in blind spots in the cleaning process. Secondly, fixed filter screen structures are difficult to adapt to the dynamic grading requirements of sand with different particle sizes, easily leading to filter pore blockage or fine sand loss. Moreover, most equipment lacks a targeted design for drainage systems, and residual wastewater after sand washing easily forms sediment at the bottom of the tank, affecting continuous operation efficiency and increasing the difficulty of subsequent cleaning. In addition, existing technologies often use separate equipment for crushing and washing processes, resulting in a lengthy process flow, large equipment footprint, and difficulty in achieving integrated crushing-washing-filtration treatment, making it inconvenient to use. Utility Model Content

[0003] To overcome the technical defects of the existing technology, this utility model provides a calcium carbonate sand washing device, which has the effects of improving the uniformity of washing and adjusting the size of the filter holes.

[0004] The technical solution adopted by this utility model is as follows: it includes a sand washing box and a box door placed on the ground. The top of the sand washing box has a feed inlet, and the side of the sand washing box has a drain outlet. The box door is hinged to the front side of the sand washing box. A mounting frame is fixed to one side of the sand washing box, and a pre-crushing turning component is fixedly installed on the mounting frame. Adjustable filter components for filtering wastewater are fixedly installed on both sides of the sand washing box. The adjustable filter components are located below the pre-crushing turning component. A water storage device is provided on the other side of the sand washing box. A water outlet pipe is fixedly installed through the top of the water storage device, and a pump body is installed on the outside of the water outlet pipe.

[0005] Preferably, in order to guide the water inside the water storage component into the pre-crushing agitator and the sand washing tank, a three-way pipe is fixed to the outside of the other end of the water outlet pipe. A first connecting pipe is fixedly installed at one end of the three-way pipe, and the other end of the first connecting pipe is rotatably installed on the pre-crushing agitator. A second connecting pipe is fixedly installed at the top of the three-way pipe, and the other end of the second connecting pipe passes through and is fixed to the inner wall of the top of the sand washing tank.

[0006] Preferably, in order to guide the wastewater, a trapezoidal water guide platform with a hydrophobic coating on the top is fixed to the inner wall of the bottom of the sand washing tank, and two extrusion plates are fixed inside the sand washing tank and are located on both sides of the pre-crushing turning component.

[0007] Preferably, in order to continuously wash calcium carbonate sand, the water storage device consists of a water storage tank and a water injection pipe. The water storage tank is located on the other side of the sand washing tank, and one end of the water injection pipe is inserted through and fixed to the top of the water storage tank.

[0008] Preferably, in order to pre-crush the large volume of calcium carbonate sand, the pre-crushing agitator includes a motor for driving and a hollow rotating shaft. The motor is fixedly mounted on the mounting frame, and one end of the rotating shaft is mounted on the output end of the motor. Agitating blade is fixed on the outside of the rotating shaft, and a water outlet is provided on the agitating blade. An installation shaft is rotatably mounted inside the sand washing box, and a crushing roller is fixed on the outside of the installation shaft.

[0009] Preferably, in order to drive the rotating shaft and the mounting shaft to rotate synchronously, a synchronizing element is fixedly installed on the outer side of the rotating shaft and the mounting shaft. The synchronizing element consists of a synchronizing pulley and a synchronizing belt.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figures 1-5 As shown, this embodiment provides a calcium carbonate sand washing device, including a sand washing box 1 and a box door 2 placed on the ground. The top of the sand washing box 1 has a feed inlet, and the side of the sand washing box 1 has a drain outlet. The box door 2 is hinged to the front of the sand washing box 1. The calcium carbonate sand inside the sand washing box 1 can be processed by opening and closing the box door 2. A mounting frame is fixed on one side of the sand washing box 1, and a pre-crushing turning component 3 is fixedly installed on the mounting frame. Adjustable filter components 4 for filtering sewage are fixedly installed on both sides of the sand washing box 1. The adjustable filter components 4 are located below the pre-crushing turning component 3. A water storage component 5 is provided on the other side of the sand washing box 1. A water outlet pipe 6 is fixedly installed through the top of the water storage component 5, and a pump body is installed on the outside of the water outlet pipe 6.

[0021] A three-way pipe 7 is fixed to the outer side of the other end of the outlet pipe 6. A first connecting pipe 8 is fixedly installed at one end of the three-way pipe 7. The other end of the first connecting pipe 8 is rotatably installed on the pre-crushing turning component 3. A second connecting pipe 9 is fixedly installed at the top of the three-way pipe 7. The other end of the second connecting pipe 9 passes through and is fixed to the inner wall of the top of the sand washing box 1. A trapezoidal water guide platform 10 with a hydrophobic coating on the top is fixed to the inner wall of the bottom of the sand washing box 1. An extrusion plate 11 is fixed inside the sand washing box 1. The extrusion plate 11 works in conjunction with the pre-crushing turning component 3 to improve the crushing effect on calcium carbonate sand. There are two extrusion plates 11, which are located on both sides of the pre-crushing turning component 3. The water storage component 5 consists of a water storage tank and a water injection pipe. The water storage tank is located on the other side of the sand washing box 1. One end of the water injection pipe passes through and is fixed to the top of the water storage tank. The other end of the water injection pipe is installed on a faucet, so that the calcium carbonate sand can be continuously washed.

[0022] In actual use, the calcium carbonate sand to be cleaned is manually poured into the sand washing tank 1 through the feed inlet. Under the action of the pre-crushing and turning component 3, the calcium carbonate sand can not only be pre-crushed, but also turned over. During the cleaning process, the pump body can pump the water source inside the water storage component 5 into the water outlet pipe 6. The water source inside the water storage tank is divided into the first connecting pipe 8 and the second connecting pipe 9 through the three-way pipe 7. The first connecting pipe 8 injects high-pressure water into the pre-crushing and turning component 3 and sprays it out through the water outlet hole on the turning blade 303 to form a dynamic flushing water flow. The second connecting pipe 9 sprays auxiliary water flow onto the top inner wall of the sand washing tank 1 to achieve multi-angle washing of the sand. At the same time, the adjustable filter component 4 can filter the sewage. After double-layer filtration, the sewage is discharged from the drain outlet. The hydrophobic coating of the trapezoidal water guide platform 10 accelerates the flow of residual sewage to the drain outlet, realizing the coordinated operation of sand crushing, turning and flushing, sewage filtration and rapid sewage discharge.

[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 4 As shown, the pre-crushing turning assembly 3 includes a motor 301 for driving and a hollow rotating shaft 302. The motor 301 is fixedly mounted on the mounting frame. One end of the rotating shaft 302 is mounted on the output end of the motor 301. Turning blades 303 are fixed on the outside of the rotating shaft 302. Water outlet holes are provided on the turning blades 303. The sand washing box 1 is rotatably mounted with a mounting shaft 304. A crushing roller 305 is fixed on the outside of the mounting shaft 304. A synchronizing element 306 is fixedly mounted on the outside of the rotating shaft 302 and the mounting shaft 304. The synchronizing element 306 consists of a synchronizing wheel and a synchronizing belt. The synchronizing wheel is fixedly mounted on the outside of the rotating shaft 302 and the mounting shaft 304. The synchronizing belt is engaged on the outside of the two synchronizing wheels. Under the action of the synchronizing belt, the two synchronizing wheels can be driven to rotate simultaneously, so that the rotating shaft 302 and the mounting shaft 304 can rotate synchronously.

[0024] When this utility model is in use, the motor 301 starts, and its output end drives the rotating shaft 302 to rotate. The agitating blades 303 on the rotating shaft 302 rotate accordingly. Under the action of the synchronizing component 306, the mounting shaft 304 rotates synchronously with the rotating shaft 302, so that the crushing roller 305 can pre-crush the calcium carbonate sand. During the rotation of the agitating blades 303, the water outlet can evenly spray water onto the calcium carbonate sand, forming a dynamic scouring, which helps to improve the cleaning effect. After pre-crushing and agitation, the impurities inside the calcium carbonate sand are more easily washed out by the water flow, thereby improving the uniformity of cleaning and the efficiency of impurity separation.

[0025] As a technical optimization solution of this utility model, specifically as follows: Figure 5 As shown, the adjustable filter assembly 4 includes a fixed plate 401 and a second motor 402. The fixed plate 401 is fixedly installed on both sides of the sand washing box 1, and the second motor 402 is fixedly installed on one side of one of the fixed plates 401. The output end of the second motor 402 is rotatably installed on the other side of the fixed plate 401. The two ends of the alloy filter screen 403 are respectively installed on the outer side of the output shafts of the two second motors 402. A filter plate 404 is fixed inside the sand washing box 1. Filter holes are opened on both the alloy filter screen 403 and the filter plate 404. The bottom of the alloy filter screen 403 is tightly attached to the top of the filter plate 404.

[0026] When this utility model is in use, the second motor 402 starts, and its output shaft drives the alloy filter screen 403 to rotate, facilitating the unwinding and winding of the alloy filter screen 403. By adjusting the relative position between the alloy filter screen 403 and the filter plate 404, the size of the filter holes can be adjusted to meet the filtration needs of calcium carbonate sand with different particle sizes. During the sand washing process, the alloy filter screen 403 and the filter plate 404 work together to effectively intercept impurities in the wastewater, preventing impurities from entering the sewage outlet and causing blockage. At the same time, the double-layer filtration structure formed by the alloy filter screen 403 and the filter plate 404 means that if the alloy filter screen 403 is damaged, it can be replaced separately, reducing the operating cost and improving the practicality of the device.

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