Description

Technical Field

[0001] The utility model relates to the field of grinding equipment, in particular to an automatic cleaning device for grinding mortar. Background Art

[0002] Lapping, a key surface finishing process, is widely used for leveling and polishing a variety of materials, including ceramics, glass, and metal. During this process, the lapping fluid plays a crucial role, not only lubricating the lapping area but also helping to remove and transport tiny particles generated by the cutting process. To improve lapping fluid utilization and reduce the cost of consumable materials, the lapping fluid is often recycled.

[0003] However, the grinding slurry formed by mixing the slurry generated during the grinding process with the grinding fluid tends to deposit in the circulation system's pipes and grinding discs. This accumulation of sediment can not only cause pipe blockages but also seriously affect the circulation of the slurry, thereby reducing grinding efficiency and quality. In addition, the slurry containing grinding sand and product powder generally requires proper treatment before discharge. However, due to space and cost constraints, many factories do not have dedicated underground wastewater collection systems, so they need to rely on equipment-side solutions to collect and treat this waste.

[0004] The current common method for cleaning mortar involves manually removing a mortar pump from the mortar bucket, pouring out the mortar, and replacing it with clean water for cleaning. This method is cumbersome to operate, and there is also the problem of water overflow affecting the cleanliness of the working environment. In addition, although technicians in the prior art have used water tanks to collect waste liquids, some problems still exist. For example, when the slurry flows into the water tank, if the flow rate is too large or changes suddenly, it is easy for the slurry to splash out of the water tank, polluting the surrounding environment and affecting the cleanliness and hygiene of the workplace; slurry splashing can also contaminate the inner wall of the water tank and the surrounding area, requiring frequent cleaning and maintenance, increasing the difficulty and workload of cleaning; slurry splashing out of the water tank may not be completely collected, resulting in slurry waste and increasing production costs; finally, it is necessary to stop work frequently to clean the splashed slurry, which affects production efficiency and increases the complexity and inconvenience of operation. Therefore, there is an urgent need to develop an automated cleaning device to simplify the operating process, improve cleaning efficiency, and ensure a clean and safe working environment. Utility Model Content

[0005] The purpose of the present invention is to solve or alleviate the above problems, and to focus on solving the problem of pollution and waste caused by slurry splashing, and to propose an automatic cleaning device for grinding mortar.

[0006] The utility model is achieved through the following technical solutions:

[0007] An automatic cleaning device for grinding mortar, comprising a mortar barrel, wherein the mortar barrel is provided with a clean water pipe, a mortar pump, and a return mortar hose I, wherein the upper end of the return mortar hose I is provided with a return mortar port, the automatic cleaning device further comprising a water tank and a return mortar hose II disposed in the water tank; a water diversion trough is provided below the return mortar port, wherein a partition plate is provided inside the water diversion trough to divide the water diversion trough into a left chamber and a right chamber; the lower ends of the left chamber and the right chamber are respectively provided with notches and are connected to the return mortar hose I and the return mortar hose II, respectively;

[0008] The partition plate is wedge-shaped; the thickness of the partition plate gradually increases along the direction in which the slurry flows into the mortar barrel; a protrusion is provided at the lower end of the partition plate, and a groove for accommodating the protrusion is provided at the lower end of the water diversion trough, and first springs 311 connecting the protrusion and the inner wall of the groove are provided on both sides of the protrusion; a bracket I matching its inner wall is provided in the return slurry hose I; a driving rod is provided on the bracket, and a protrusion is provided at the upper end of the driving rod, and a second spring I connecting the protrusion and the inner wall of the water diversion trough is provided; based on the perpendicular midline of the cross section of the partition plate, a driving rod II, a protrusion, a second spring II, a bracket II and a first spring are provided in the right chamber and in its notch, which are mirror images of the driving rod, the protrusion, the second spring I and the bracket I.

[0009] Conventional grinding equipment lacks a water tank to collect wastewater. When wastewater needs to be dumped, the mortar bucket is emptied and cleaned, leading to environmental pollution and inefficient cleaning. Furthermore, after adding a water tank and diverter trough, if the wastewater flow rate suddenly increases or changes, the fixed chamber volume of the diverter trough cannot be adjusted in time, potentially causing slurry splashing, polluting the work environment, and reducing the efficiency and service life of the cleaning equipment.

[0010] The interior of the water diversion trough of the present invention is divided into two left and right chambers by a partition plate. The left chamber is connected to the mortar barrel through the return slurry hose I, and the right chamber is connected to the water tank through the return slurry hose II, thereby achieving effective diversion and collection of waste liquid. In addition, the wedge-shaped design of the partition plate allows the slurry to gradually diffuse in the direction of flowing into the mortar barrel, thereby reducing the impact force of the slurry on the water diversion trough. When the mortar enters the water diversion trough through the return slurry hose, its impact force acts on the bracket, and then acts on the drive rod, causing it to move downward, thereby compressing the first spring connecting the protrusion and the inner wall of the groove. The protrusion contacts the inclined surface of the partition plate, causing the partition plate to move to the right, increasing the chamber size of the water diversion trough, reducing the fluid impact force, and facilitating the collection and flow of waste liquid. Conversely, when the slurry flow decreases or disappears, the bracket moves upward during the return process of the first spring, allowing the protrusion to move away from the partition plate. The second spring resets, and the chamber volume returns to its original state, allowing the waste liquid to flow into the water tank more quickly for collection.

[0011] Preferably, a hydraulic cylinder is connected to the side wall of the water diversion trough, with one end of a hydraulic cylinder support rod fixed to the lower end of the hydraulic cylinder, and the other end of the hydraulic support rod is connected to the water tank. Through the hydraulic cylinder, the automatic cleaning device can more flexibly adjust the position of the water diversion trough to respond to dynamic changes in the fluid, thereby optimizing the separation effect and preventing splashing caused by excessive inflow of slurry.

[0012] Preferably, a wedge-shaped plate is fixedly provided on one side of the protrusion close to the partition plate, and the inclined surface of the partition plate matches the wedge-shaped plate. The wedge-shaped plate can further increase the movement of the partition plate and can scrape off impurities attached to the surface of the partition plate during the movement.

[0013] Preferably, the support is provided with a filter screen for filtering impurities in the slurry. When the slurry flows into the water diversion tank, the filter screen blocks impurities or solid particles in the slurry and prevents them from further entering the water tank or the reflux system.

[0014] Preferably, the bottoms of the mortar bucket and the water tank are both provided with telescopic brackets and rollers; a water receiving tray is provided at the lower end of the telescopic bracket for receiving the slurry splashed in the mortar bucket and the water tank.

[0015] Preferably, the bottom sidewall of the mortar bucket is provided with an opening, within which is a drain valve. This valve allows the contents of the mortar bucket to be directly discharged when necessary, without the need to empty the entire bucket. Furthermore, with the telescopic bracket, the drain valve can be aligned with the water tank to direct waste liquid there. The drain valve design facilitates rapid drainage.

[0016] Preferably, the outer walls of the clean water pipe and the slurry return hose I are both provided with pipe sleeves.

[0017] Preferably, the cross section of the wedge-shaped plate is rectangular perpendicular to the slurry flow direction. The wedge-shaped plate can act on the partition plate with a larger area, further enhancing the effect of scraping off impurities attached to the surface.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] 1. The utility model provides a slurry return hose II and a water tank, so that the waste liquid is directly discharged into the water tank through the drain valve or the water distribution trough of the mortar barrel, thereby reducing the cleaning frequency of the mortar barrel and improving work efficiency.

[0020] 2. The water diversion trough of the present invention is equipped with a bracket, a driving rod, a movable partition plate and other components, which can adaptively adjust the chamber volume of the water diversion trough according to the flow rate of the slurry inflow. When the flow rate increases, the partition plate moves to the right to increase the chamber volume, reduce the impact force of the slurry, and accelerate the circulation effect. When the flow rate decreases, the partition plate returns to its original state, so that the chamber volume is restored to adapt to the circulation efficiency of small flow rates. In addition, the present invention also sets a filter on the bracket to further reduce the probability of impurities entering the mortar barrel. At the same time, the present invention sets a wedge plate to scrape impurities on the surface of the partition plate during the above-mentioned change in chamber volume. The above various effects are superimposed during the actual working process, further enhancing the cleaning effect of the present invention.

[0021] 3. The utility model is also provided with a telescopic bracket, rollers and a drain valve, which improves the overall operational convenience. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without the need for creative work are within the scope of protection of the present invention. The schematic implementation methods of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual research and development and use stage.

[0032] Unless otherwise defined, technical or scientific terms used in this utility model should have the ordinary meaning understood by people with ordinary skills in the field to which this utility model belongs. The words "first", "second" and similar terms used in this utility model do not indicate any order, quantity or importance, but are simply used to distinguish different components. The words "include" or "comprising" and similar words mean that the elements or objects listed before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0033] The currently widely used mortar cleaning method involves manually removing the mortar pump from the mortar bucket, pouring out the mortar, and replacing it with fresh water for cleaning. This process is not only cumbersome to operate, but also often pollutes the working environment due to water overflow. Although water tanks are used to collect waste slurry in the prior art, this method still has drawbacks. For example, when the slurry flow rate suddenly increases or changes, the slurry can easily splash out of the water tank, which not only pollutes the surrounding environment but also affects the cleanliness and hygiene of the workplace. In addition, the splashed slurry causes the water tank and its surrounding areas to require frequent cleaning and maintenance, increasing the workload and cleaning difficulty. Failure to effectively collect slurry also results in a waste of resources and increases production costs. In addition, production often needs to be suspended to clean the splashed slurry, which reduces production efficiency and increases the complexity and inconvenience of operation. Therefore, there is an urgent need to develop an automated cleaning device that can simplify the operating process, improve cleaning efficiency, and ensure a clean and safe working environment.

[0034] Example 1:

[0035] Please refer to the attached Figure 1 To the attached Figure 5 As shown, an automatic cleaning device for grinding mortar includes a mortar barrel 1, in which a clean water pipe 8, a mortar pump 4 and a return mortar hose I 5 are provided. The upper end of the return mortar hose I 5 is provided with a return mortar port 10. The automatic cleaning device also includes a water tank 2 and a return mortar hose II 51 provided in the water tank 2; a water diversion trough 3 is provided below the return mortar port 10, and a partition plate 31 is provided inside the water diversion trough 3 to divide it into a left chamber and a right chamber; the lower ends of the left chamber and the right chamber are respectively provided with notches 39 and are connected to the return mortar hose I 5 and the return mortar hose II 51 respectively; the partition plate 31 is wedge-shaped; the thickness of the partition plate 31 gradually increases along the direction in which the slurry flows into the mortar barrel 1 ; A protrusion is provided at the lower end of the partition plate 31, and a groove is provided at the lower end of the water diversion trough 3 to accommodate the protrusion. First springs 311 connecting the protrusion and the inner wall of the groove are provided on both sides of the protrusion; a bracket Ⅰ36 matching its inner wall is provided in the return hose Ⅰ5; a driving rod is provided on the bracket, and a protrusion is provided at the upper end of the driving rod, and a second spring Ⅰ34 connecting the protrusion and the inner wall of the water diversion trough 3 is provided; based on the perpendicular midline of the cross section of the partition plate 31, a driving rod Ⅱ321, a protrusion, a second spring Ⅱ341, a bracket Ⅱ361 and a first spring 311 are provided in the right chamber and in its notch 39, which are mirror images of the driving rod, the protrusion, the second spring Ⅰ34 and the bracket Ⅰ36.

[0036] It should be noted that the mortar barrel 1 is used to accommodate grinding mortar, and is equipped with a clean water pipe 8, a mortar pump 4 and a return slurry hose I5. The upper end of the return slurry hose I5 is provided with a return slurry port 10, which is used to recirculate the mortar into the mortar barrel 1. The utility model adds a water tank 2 and a return slurry hose II51 provided in the water tank 2, as well as a water diversion trough 3 arranged below the return slurry port 10. The interior of the water diversion trough 3 is divided into two left and right chambers by a partition plate 31. The left chamber is connected to the mortar barrel 1 through the return slurry hose I5, and the right chamber is connected to the water tank 2 through the return slurry hose II51, thereby realizing effective diversion and collection of waste liquid. In addition, the wedge-shaped design of the partition plate 31 allows the slurry to gradually diffuse in the direction of flowing into the mortar barrel 1, thereby reducing the impact force of the slurry on the water diversion trough 3.

[0037] When the mortar passes through the return hose and enters the water diversion trough 3, its impact force acts on the bracket, and then on the drive rod, causing it to move downward, thereby compressing the first spring 311 connecting the protrusion and the inner wall of the groove. The protrusion contacts the inclined surface of the partition plate 31, causing the partition plate 31 to move to the right, increasing the chamber volume of the water diversion trough 3, which is conducive to the collection and flow of waste liquid, preventing splashing and pollution of the environment. When the slurry flow rate is large, the bracket moves downward, the chamber volume increases, and thus reduces the impact force of the fluid. Conversely, when the slurry flow rate decreases or disappears, the bracket moves upward during the reset of the first spring 311, the partition plate 31 resets, and the chamber volume decreases, allowing the waste liquid to flow into the water tank 2 more quickly for collection. As an alternative, the partition plate 31 can be designed to be adjustable, allowing the separation position to be automatically adjusted according to the mortar flow rate, rather than a fixed wedge design. In addition, the connection method of the water diversion trough 3 can be changed from using a fixed spring to using an adjustable hydraulic or pneumatic system to adapt to mortars of different viscosities and flow rates. The above design effectively manages the recycling of mortar and cleaning fluid, reduces the splashing of slurry and the leakage of waste liquid, and improves cleaning efficiency.

[0038] A thin sheet is welded to the inner wall of the mortar barrel (1) to support the barrel lid. The sheet is 1-2 cm thick and is sunken 2-3 cm below the barrel edge to prevent the return hose from falling out of the return hose sleeve and spilling slurry. A 3-5 cm high water retaining plate surrounds the mortar pump (4) hole to prevent mortar and water spilled on the barrel lid from seeping into the mortar pump (4) motor, which could affect its service life.

[0039] As a further preference of this embodiment, a hydraulic cylinder 37 is connected to the side wall of the water distribution tank 3 , one end of a hydraulic cylinder support rod 38 is fixed to the lower end of the hydraulic cylinder 37 , and the other end of the hydraulic support rod is connected to the water tank 2 .

[0040] It should be noted that the slurry flow direction can be changed by manually adjusting the horizontal position of the water diversion trough 3, or by providing a power element such as a pneumatic cylinder or hydraulic cylinder 37. The hydraulic cylinder 37 allows the automatic cleaning device to more flexibly adjust the position of the water diversion trough 3 in response to dynamic changes in the fluid, thereby optimizing the separation effect and preventing splashing caused by excessively rapid inflow of slurry.

[0041] The bottom sidewall of the mortar bucket 1 is provided with an opening, within which is a drain valve 12. It should be noted that drain valve 12 allows the contents of the mortar bucket 1 to be directly discharged when necessary, without having to empty the entire bucket 1. Furthermore, with the telescopic bracket 9, drain valve 12 can be aligned with the water tank 2 to direct waste liquid there. The design of drain valve 12 facilitates rapid drainage while also allowing for thorough cleaning of the mortar bucket 1.

[0042] As a further preference of this embodiment, a wedge-shaped plate is fixedly provided on one side of the protrusion close to the partition plate 31 , and the inclined surface of the partition plate 31 matches the wedge-shaped plate.

[0043] It should be noted that the wedge plate can further increase the movement of the partition plate 31, and during the movement, it can scrape off impurities attached to the surface of the partition plate 31, further achieving a clean collection effect. The wedge plate also strengthens the connection with the partition plate 31, ensuring the stable movement of the partition plate 31. If the wedge plate design is not adopted, the connection between the partition plate 31 and the water diversion trough 3 may be affected, causing friction or instability in the partition plate 31 during movement, thereby affecting the movement effect of the partition plate 31. In the absence of a wedge plate, it may be necessary to add other fixing devices or adopt a more complex structural design to ensure the stable movement of the partition plate 31.

[0044] There is a better solution in this embodiment, in which a filter screen for filtering impurities in the slurry is provided on the bracket.

[0045] It should be noted that when the slurry flows into the water distribution tank 3, the filter will play a filtering role, blocking impurities or solid particles in the slurry, thereby purifying the slurry and preventing it from further entering the water tank 2 or the reflux system, extending the service life of the equipment and reducing the frequency of maintenance and cleaning.

[0046] This embodiment has a better solution. The bottom of the mortar bucket 1 and the water tank 2 are both provided with a telescopic bracket 9 and a roller 6; the lower end of the telescopic bracket 9 is provided with a water receiving tray 7 for receiving the slurry splashed in the mortar bucket 1 and the water tank 2.

[0047] It should be noted that the telescopic bracket 9 and the roller 6 enable the mortar bucket 1 and the water tank 2 to be easily moved, which is convenient for position adjustment and cleaning. In addition, a water collecting tray 7 is provided at the lower end of the telescopic bracket 9. The water collecting tray 7 is located on the ground and is 8-12 cm high. It is used to collect the slurry splashed from the mortar bucket 1 and the water tank 2 to prevent the working area from being contaminated. There are three rollers 6 at the bottom of the mortar bucket 1, including one universal wheel and two driven wheels. When taken out separately, they can be pushed forward on the ground. There are four rollers 6 at the bottom of the water tank 2, including two universal wheels and two driven wheels. When taken out separately, they can be pushed forward on the ground. When the wastewater in the water tank 2 needs to be transported out for treatment, it is raised to a certain height, its bottom is dragged with a forklift, and it is transported out from the back of the equipment.

[0048] Example 2:

[0049] As a further optimization of the above embodiment, the outer walls of the clean water pipe 8 and the slurry return hose I 5 are both provided with pipe sleeves. The cross section of the wedge plate is rectangular perpendicular to the slurry flow direction.

[0050] It should be noted that the use of pipe sleeves effectively protects the clean water pipe 8 and the return slurry hose I5, extending their service life and reducing the frequency of maintenance and replacement. Furthermore, the sleeves provide additional thermal and sound insulation, improving the overall operational efficiency and safety of the system. The extended wedge plate allows for a larger area of ​​action on the partition plate 31, further enhancing the scraping effect on surface impurities and optimizing the cleaning and treatment performance of the entire system.
