[0025] Example:
[0026] like Figure 1 As shown, this embodiment provides an anti-deposition device suitable for use in a wet shot blasting machine, including a liquid supply box 1, a liquid spray pipe 2 and a liquid storage tank 3 for storing a working liquid, a particle deposition area 311 is formed in the liquid storage tank 3, the liquid spray pipe 2 has a liquid inlet 211 and a liquid spray port 221 that are interconnected, the liquid inlet 211 is connected to the liquid supply box 1, and the liquid spray port 221 is located in the liquid storage tank 3 and faces the particle deposition area 311, so that the material deposited in the particle deposition area 311 can flow through the impact of the liquid in the liquid spray pipe 2.
[0027] The anti-deposition device in this embodiment includes a liquid supply box 1, a liquid spray pipe 2 and a liquid storage tank 3 for storing a working liquid. The working liquid is a mixture of steel sand and water. Of course, in other embodiments, the working liquid can also be a mixture of other hard abrasives such as diamond and water. The wet shot blasting machine ejects the working liquid at high speed onto the surface of the workpiece to be processed, thereby removing the iron oxide and other impurities on the surface of the workpiece. During the operation of the wet shot blasting machine, the working liquid will be ejected onto the surface of the workpiece to be processed under the action of the high-speed rotating turbine motor to achieve surface cleaning of the workpiece. However, due to the influence of gravity, the steel sand in the liquid storage tank 3 is easily deposited on some areas with poor fluidity on the bottom wall 31 of the liquid storage tank 3, and a particle deposition area 311 is formed on the bottom wall 31. The steel sand in the particle deposition area 311 will accumulate or even agglomerate. In the long run, it will greatly affect the performance and service life of the working liquid, reduce the surface cleaning effect of the shot blasting machine, increase production costs and affect the surface quality of the workpiece. In this embodiment, the liquid supply tank 1 is used to store water and provide a stable water supply to the liquid storage tank 3, and the liquid spray pipe 2 is used to guide the water in the liquid supply tank 1 to the liquid storage tank 3. The two ends of the liquid spray pipe 2 are respectively a liquid inlet 211 and a liquid spray port 221. The liquid inlet 211 is connected to the liquid supply tank 1 to ensure the continuous supply of water. The liquid spray port 221 directly sprays water to the particle deposition area 311 on the bottom wall 31 of the liquid storage tank 3, disturbing the steel sand deposited in the particle deposition area 311, improving the fluidity of the steel sand and the working fluid, reducing the agglomeration of the steel sand at the bottom, reducing the production cost, and thus improving the surface cleaning efficiency of the wet shot blasting machine. It should be noted that the particle deposition area 311 refers to the area where more steel sand is deposited, that is, the flow dead angle, and liquid storage tanks 3 of different shapes have different flow dead angles.
[0028] The bottom wall 31 of the liquid storage tank 3 of the utility model is generally set to a rectangle, so that there is an end angle position inside the liquid storage tank. This structure has some specific flow patterns in fluid mechanics, that is, the flow of the fluid in the liquid storage tank 3 is usually uneven, especially in the end angle area, the fluid may generate vortexes or backflows during the flow process, and these phenomena will reduce the fluidity of the particles. Therefore, the end angle area is prone to form a flow dead angle, that is, the flow speed of the fluid will be relatively slow in the end angle area, thereby reducing the possibility of particles being taken away, and then forming a particle deposition area 311. The liquid spray port 221 is set toward the end angle (i.e., the particle deposition area 311) of the bottom wall 31 of the liquid storage tank 3, so that the water flow sprayed from the liquid spray port 221 can directly impact the particle deposition area 311, effectively flush and take away the steel sand particles deposited therein, significantly reduce the accumulation of steel sand at the bottom of the liquid storage tank 3, and ensure the fluidity and utilization rate of steel sand. In addition, it should be noted that when the bottom wall 31 of the liquid storage tank 3 is no longer rectangular, its end corners do not necessarily form the particle deposition area 311 , and the formation of the particle deposition area 311 is related to the shape of the liquid storage tank 3 and its bottom wall 31 .
[0029] The particle deposition area 311 in this embodiment is formed at the end corner position. In actual setting, the liquid spraying port can be set toward the end corner position.
[0030] In one embodiment of the utility model, the liquid spraying port 221 is configured as a plurality of liquid spraying ports 221, and the plurality of liquid spraying ports 221 are arranged in a ring shape to form a reflux vortex in the liquid storage tank 3. In this embodiment, the liquid spraying port 221 is arranged in a ring shape, so that when in use, when the plurality of liquid spraying ports 221 spray at the same time, a reflux vortex can be formed at the bottom of the liquid storage tank 3, thereby better driving the flow of the steel sand deposited in the particle deposition area 311, avoiding the steel sand in a certain place from being in a static state for a long time, and reducing the occurrence of accumulation, rust and agglomeration. In actual setting, the orientation of the plurality of liquid spraying ports 221 can be set to a clockwise distribution or a counterclockwise distribution according to actual conditions, wherein when setting the orientation of the liquid spraying port 221, it is necessary to consider the direction of the water flow, and set the orientation of the liquid spraying port 221 to the direction of the water flow, so that the impact force of the spraying is stronger during spraying, and a better anti-deposition effect is achieved.
[0031] In order to facilitate the arrangement of the liquid spray pipe 2, the liquid spray pipe 2 of the utility model includes a main pipe 21 connected to the liquid supply box 1 and a plurality of branch pipes 22 connected to the liquid storage tank 3. The liquid inlet is arranged on the main pipe 21, and the branch pipe 22 forms a liquid spray port 221. The main pipe 22 is constructed to surround the outside of the liquid storage tank 3. The plurality of branch pipes 22 are distributed along the surrounding direction of the main pipe 21 to form a ring. A water pump 212 is arranged on the main pipe 21. In this embodiment, see the attached Figure 2 The main pipe 21 is set to a structure surrounding the liquid storage tank 3, and the branch pipes 22 only need to be arranged along the surrounding direction of the main pipe 21 to conveniently form a ring structure, making production and design more reasonable.
[0032] In addition, in the present embodiment, the liquid spray pipe 2 adopts a structure combining a main pipe 21 and a branch pipe 22. The main pipe 21 is provided with a liquid inlet 211, which is connected to the liquid supply tank 1 to ensure that the water in the liquid supply tank 1 can smoothly enter the liquid spray pipe 2. A water pump 212 is also installed on the main pipe 21. The function of the water pump 212 is to provide sufficient water pressure to ensure that water can smoothly pass through the liquid spray pipe 2 and spray to the liquid storage tank 3. The branch pipe 22 can connect the main pipe 21 and the liquid storage tank 3, and the number of the branch pipes 22 can be determined according to the size and shape of the liquid storage tank 3. Each branch pipe 22 is provided with a liquid spray port 221 directly facing the particle deposition area 311 of the liquid storage tank 3. By reasonably arranging the branch pipes 22 and the liquid spray ports 221, it is possible to achieve accurate water spraying to multiple particle deposition areas 311 in the liquid storage tank 3, thereby achieving better cleaning and circulation effects.
[0033] The branch pipe 22 extends obliquely toward the bottom wall 31 of the liquid storage tank 3 so that the liquid spraying port 221 is aligned with the particle deposition area 311 , and the angle between the branch pipe 22 and the main pipe 21 is 45°.
[0034] In this embodiment, the branch pipe 22 does not extend vertically downward, but extends obliquely toward the bottom wall 31 of the liquid storage tank 3, ensuring that the liquid spray port 221 can be directly aligned with the particle deposition area 311, so that the water flow can directly impact the particle deposition area 311, effectively flushing the deposited particles. Based on the optimization selection of fluid mechanics and actual application effects, the angle between the branch pipe 22 and the main pipe 21 is set to 45°, which can ensure that the water flow has sufficient impact force while reducing the energy loss caused by excessive angles. In addition, the 45° angle also makes the branch pipe 22 more convenient and flexible during installation and layout.
[0035] The plurality of branch pipes 22 are evenly distributed along the water flow direction in the main pipe 21 .
[0036] In this embodiment, the evenly distributed branch pipes 22 can ensure that the water flow is evenly distributed throughout the liquid storage tank 3, avoiding poor cleaning effects in certain areas due to insufficient water flow. When the branch pipes 22 are evenly distributed, the water flow borne by each branch pipe 22 is relatively balanced, which helps to maintain the stability and reliability of the entire water spray system. In this embodiment, the water flow in the main pipe 21 flows clockwise around the liquid storage tank 3, so the multiple branch pipes 22 are also evenly distributed clockwise around the liquid storage tank 3, reducing the problem of local over- or under-scouring caused by uneven water flow, thereby maintaining the stability and fluidity of the steel grit in the liquid storage tank 3.
[0037] A clearance hole is provided on the side wall 32 of the liquid storage tank 3 , and the liquid spraying pipe 2 passes through the clearance hole and enters the liquid storage tank 3 .
[0038] In this embodiment, when installing the liquid spray pipe 2, the main pipe 21 should first be fixed to the outside of the liquid storage tank 3 and ensure that its position is stable, and then the branch pipes 22 should be passed through the clearance holes on the side wall 32 one by one to ensure that the liquid spray port 221 is facing the particle deposition area 311 inside the liquid storage tank 3. Sealing material can also be added between the liquid spray pipe 2 and the clearance hole to improve the sealing performance.
[0039] The liquid spraying pipe 2 is arranged at a distance of 10 to 20 cm from the bottom wall of the liquid storage tank 3 .
[0040] In this embodiment, the distance between the clearance hole and the bottom wall 31 is set within the range of 10 to 20 cm, which can ensure that the liquid spraying port 221 can directly impact the particle deposition area 311 when spraying water, thereby achieving effective flushing of these areas. When the distance between the clearance hole and the bottom wall 31 is less than 10 cm, the liquid spraying port 221 is too close to the bottom wall 31, resulting in poor flushing effect. When the distance between the clearance hole and the bottom wall 31 is greater than 10 cm, the liquid spraying port 221 is too far from the bottom wall 31, resulting in the water flow being weakened before reaching the bottom wall 31.
[0041] The anti-deposition device further comprises a liquid return pipe 4 and a liquid return pump arranged on the liquid return pipe 4 . One end of the liquid return pipe 4 is connected to the bottom of the liquid storage tank 3 , and the other end is connected to the liquid supply tank 1 .
[0042] In this embodiment, the anti-deposition device further includes a liquid return pipe 4 and a liquid return pump. In a complete anti-deposition device, the liquid return system is also crucial. The liquid return system is composed of a liquid return pipe 4 and a liquid return pump arranged on the liquid return pipe 4, which can recover the working liquid at the bottom of the liquid storage tank 3 and re-transport it to the liquid supply tank 1 to achieve the recycling of the working liquid, reduce the waste of water resources, and also reduce the production cost.
[0043] A rotary separator for filtering the working fluid is provided between the liquid storage tank 3 and the liquid return pipe 4 .
[0044] In this embodiment, the working fluid in the liquid storage tank 3 first passes through the rotary separator and then enters the liquid return pipe 4. The rotary separator uses the principle of centrifugal force to separate the particulate impurities in the working fluid from the liquid. When the working fluid enters the rotary separator, it will generate centrifugal force under the high-speed rotation inside, so that the particulate impurities are thrown to the wall of the device, and the clean water flows out through the outlet, and the water flows from the liquid return pipe 4 into the liquid supply tank 1, realizing recycling and reducing production costs.
[0045] This embodiment also provides a wet shot blasting machine, including a spraying device for spraying working fluid onto a workpiece to be processed and an anti-deposition device, wherein the anti-deposition device includes the aforementioned anti-deposition device.
[0046] The wet shot blasting machine of this embodiment realizes an efficient and clean shot blasting process by combining the injection device and the anti-deposition device, improves the cleanliness and quality of the workpiece surface, reduces production costs, and improves the stability and reliability of the equipment.
[0047] The wet shot blasting machine includes a PLC control unit, which is used to control the opening and closing of the liquid spray pipe 2 in the anti-deposition device. When steel sand accumulates in the liquid storage tank 3, the liquid spray pipe 2 can be opened by PLC program control before the wet shot blasting equipment is officially started or within 10 minutes after shutdown to impact the steel sand in the corner of the liquid storage tank 3 with water.

Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments.
