Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of quartz stone production, and particularly relates to a dust falling device for quartz stone production and processing. BACKGROUND

[0002] Quartz stone plate is widely used in the fields of building decoration and kitchen and bathroom countertop due to high hardness and strong wear resistance. However, in the production links of sawing, edge grinding, chamfering and drilling, a large amount of silicon-containing dust is generated due to the mechanical friction between the high-speed cutter and the surface of the quartz stone. At the same time, the equipment wear also brings about small iron filings. These dust and metal impurities are scattered with cooling water or air flow, which not only threatens the respiratory health of the operators, but also easily forms an explosive dust environment in the workshop. For example, a crushing device for quartz stone processing in "CN221288004U" belongs to the technical field of crushing devices, which comprises a machine body, a feeding port is formed in the upper end of the machine body, and a crushing cavity is formed in the machine body. The beneficial effect is that the crushing device for quartz stone processing adopts two groups of grading crushing roller groups to perform extrusion crushing operation on the quartz stone raw materials, so that part of the quartz stone raw materials with relatively large particles can be directly subjected to secondary crushing, thereby avoiding lifting operation and ensuring the crushing effect of the quartz stone raw materials. At the same time, after the crushing of the quartz stone raw materials is completed, the raw material particles can be directly screened and selected according to different particle sizes, the operation process is reduced, the labor amount is reduced, and the use function of the quartz stone processing crushing device can be more perfect. However, in the prior art, in order to solve the dust problem, the existing factory usually adopts a local dust hood with a bag filter, a water curtain or a water washing type dust removal device, and a permanent magnet bar or a magnetic separator is installed at a key position to adsorb iron filings, and the above device is periodically disassembled and cleaned by manual labor to complete maintenance. However, the existing treatment scheme is usually scattered, and the dust, wastewater and metal filings need to be transported multiple times between different devices, which has a long process and occupies a large area. In addition, the slurry generated by the water washing dust removal needs to be placed in a large sedimentation tank or dewatered by a filter press, and the replacement process of the filter cloth is easy to cause secondary dust raising. The permanent magnet bar is normally magnetized, and needs to be disassembled and manually scraped, which has high labor intensity. SUMMARY

The motor drives the rotating shaft and the grinding cone below it to rotate, grinding large quartz particles that fall onto the screen plate into fine particles, facilitating subsequent extrusion molding and further processing of the quartz fragments. In addition, iron filings and other debris generated during processing may also be drawn into the dust settling chamber. Initially, the strips are in an unfolded state. As the dust is introduced into the liquid, the rotation of the shaft agitates the liquid, allowing the debris to mix quickly in the water. Iron filings and other debris are quickly dispersed by the magnetic strips on the inner side of the strips. The adsorption mechanism allows for the individual collection of iron filings. After a period of time, when there are enough iron filings on the strips that need to be cleaned, the collection mechanism can be driven to move the limiting ring downwards, allowing all the strips to be collected into the assembly slot.

After the dust-suppressing liquid in the water tank is discharged, the inner sealing plate is opened, and the liquid above the inner sealing plate quickly flows down through the filter screen, which can wash the filter screen and the debris remaining on the inner wall of the lower end of the water tank, ensuring the cleanliness of the water tank as much as possible and saving labor for manual cleaning.

DETAILED DESCRIPTION

[0019] In order to make the above objectives, features and advantages of the present application more apparent, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0020] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the concept of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0021] Secondly, as referred to herein, "one embodiment" or "an embodiment" means that a specific feature, structure or characteristic can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is independent of or mutually exclusive of other embodiments.

[0022] Please refer to Figures 1-9This invention provides a technical solution: a dust suppression device for quartz stone production and processing, comprising a base 1 and a dust suppression box 2 and a water tank 3 containing dust suppression liquid. The dust suppression box 2 and the water tank 3 are mounted on the base 1. An air inlet pipe 4 and an air outlet pipe 5 are connected to the dust suppression box 2. A rotating shaft 611 is rotatably mounted at the center of the upper end of the dust suppression box 2. A grinding cone 612 is mounted at the lower end of the rotating shaft 611. A mesh plate 613 is mounted inside the lower part of the dust suppression box 2. The lower part of the grinding cone 612 is in contact with the mesh plate 613. The rotating shaft 611 has a hollow structure and its upper end is connected to the outside. The fan in the unit is detachable and connected. A strip plate 614 is rotatably connected to the lower side wall of the rotating shaft 611. A magnetic strip 615 is provided on the inner side of the strip plate 614. A collection mechanism for collecting iron filings is provided on the rotating shaft 611. The lower side of the dust settling box 2 is connected to the water tank 3 through a connecting pipe 7. The inner wall of the water tank 3 is provided with a filter screen 811 and a water pump 812. The output end of the water pump 812 is connected to the upper part of the dust settling box 2 through a conduit 813. A screw extruder 9 is provided on the base 1. The lower output end of the water tank 3 is connected to the feed port of the screw extruder 9.

[0023] like Figures 1-9 As shown, the height of the dust-suppressing liquid in the dust-suppressing box 2 is higher than that in the water tank 3. The air outlet of the air inlet pipe 4 extends into the dust-suppressing liquid and is located above the mesh plate 613. The height of the dust-suppressing liquid in the water tank 3 is higher than that of the filter screen 811. By setting the height of the dust-suppressing liquid in the water tank 3 to be lower than that in the dust-suppressing box 2, there is always a height difference between the dust-suppressing box 2 and the water tank 3. The liquid in the dust-suppressing box 2 will continuously flow into the water tank 3, and the impurities mixed in the dust-suppressing liquid will be discharged to the bottom of the water tank 3 and accumulate.

[0024] like Figures 1-9 As shown, a motor 101 is provided at the upper end of the dust collection box 2. A first gear 102 is provided at the output end of the motor 101. A second gear 103 is provided at the upper end of the rotating shaft 611 and meshes with the first gear 102. By driving the motor 101, the first gear 102 is driven to rotate, which in turn drives the second gear 103 and the rotating shaft 611 to rotate, and the grinding cone 612 below rotates in conjunction with it.

[0025] like Figures 1-9 As shown, the screen plate 613 is designed with a high edge and a low center. The center of the screen plate 613 is adapted to the lower part of the grinding cone 612. The lower end of the grinding cone 612 is provided with a grinding groove 11. By setting the edge of the screen plate 613 higher, it is easy for particulate impurities to gather towards the center under the action of gravity, so that the grinding cone 612 can grind them until the particles are small enough to fall below the screen plate 613.

[0026] like Figures 1-9As shown, the lower side wall of the rotating shaft 611 is provided with an assembly groove 121, and the upper end of the strip plate 614 is rotatably arranged in the assembly groove 121, and the edge of the strip plate 614 is sealingly connected with the assembly groove 121. The outer side of the rotating shaft 611 is provided with an air pipe 122, the upper end of the air pipe 122 extends above the liquid level of the dust-settling liquid, and the lower end of the air pipe 122 penetrates the lower end side wall of the rotating shaft 611 and extends inside. When collecting iron filings in the rotating shaft 611, the strip plate 614 is stored in the assembly groove 121, and the gas in the rotating shaft 611 is extracted outward by an external fan, which can suck out the internal iron filings together. The arrangement of the air pipe 122 can ensure that the gas in the rotating shaft 611 can be smoothly sucked out.

[0027] As shown in the drawings, Figures 1-9 The collection mechanism includes a limiting ring 131, an end ring 132 and a first cylinder 133. The limiting ring 131 and the end ring 132 are respectively slidingly arranged on the outer side of the rotating shaft 611. The upper end of the limiting ring 131 is assembled and connected with the end ring 132 through a connecting strip 134. The first cylinder 133 is arranged on the upper end of the dust-settling box 2, and the output end thereof is assembled and connected with the end ring 132. The limiting ring 131 is slidingly arranged on the upper end and the outer side of the strip plate 614. By driving the first cylinder 133 to move up and down, the overall up and down movement of the limiting ring 131 and the end ring 132 is driven. When the limiting ring 131 moves downward, the limiting ring 131 limits the strip plate 614 to be retracted into the assembly groove 121 to achieve limiting.

[0028] As shown in the drawings, Figures 1-9 The lower center of the rotating shaft 611 is provided with a fixed shaft 141, the upper end of the fixed shaft 141 is slidingly sleeved with a sleeve shaft 142, the lower end of the sleeve shaft 142 is provided with a piston 143 which is slidingly matched with the inner wall of the rotating shaft 611. The upper end of the piston 143 is provided in a conical structure. The lower part of the piston 143 is assembled and connected with the lower part of the rotating shaft 611 through a spring 144. The outer wall of the sleeve shaft 142 is hingedly arranged with the inner side of the strip plate 614 through a hinged strip 145. In the initial state, the spring 144 pushes the piston 143 to move upward, drives the hinged strip 145 to move upward, and lifts the hinged strip 145 connected to the sleeve shaft 142 to the upper end of the strip plate 614 to open it. At this time, the conical slope of the upper end of the piston 143 is just flush with the lower end of the assembly groove 121. When the strip plate 614 is closed, the strip plate 614 is closed, the lower end of the hinged strip 145 moves downward, and the sleeve shaft 142 moves downward, so that the collected iron filings can be stored in the internal space of the rotating shaft 611.

[0029] As shown in the drawings, Figures 1-9As shown, the upper end of the rotating shaft 611 is provided with a conductive ring 151, and the conductive ring 151 is connected with the magnetic strip 615 through a conductive strip 152 below the conductive ring 151. The end ring 132 at the upper end is sleeved outside the conductive ring 151, and the inner side of the end ring 132 is provided with a conductive sheet 153 electrically connected with the conductive ring 151. The conductive sheet 153 is in electrical connection with the external power supply. When the strip plate 614 is in the fully expanded state, the end ring 132 is located at the position of the upper end conductive ring 151. At this time, the conductive sheet 153 supplied with power from the external power supply is in electrical connection with the conductive ring 151, thereby generating magnetism to the magnetic strip 615 for adsorbing iron filings. The end ring 132 moves downward, and the limiting ring 131 moves downward accordingly. The strip plate 614 gradually shrinks into the assembly groove 121. After the end ring 132 moves downward by a distance, it is separated from the conductive ring 151 to realize power-off. At this time, the strip plate 614 has been closed into the assembly groove 121, and the iron filings are separated from the magnetic strip 615, which is convenient for discharge.

[0030] As shown in Figures 1-9 The upper part of the dust falling box 2 is provided with a spray pipe 161, and the spray pipe 161 is provided with a plurality of water outlets 162. The output end of the water pump 812 is communicated with the spray pipe 161 through a conduit 813. The spray pipe 161 is located outside the rotating shaft 611. By arranging the spray pipe 161, the liquid discharged from the water tank 3 into the dust falling box 2 can be sprayed in a large area, and some dust overflowing the water surface can be contacted with the liquid again to achieve the dust falling effect.

[0031] As shown in Figures 1-9 The inner wall of the water tank 3 above the filter screen 811 is provided with an outer sealing plate 171, and the outer sealing plate 171 is sealingly clamped with an inner sealing plate 172 above the outer sealing plate 171. The water pump 812 is arranged above the inner sealing plate 172. The upper end of the inner part of the water tank 3 is connected with the upper end of the inner sealing plate 172 through a second cylinder 173. The second cylinder 173 is a corrosion-resistant and waterproof cylinder.

[0032] Working principle: The dust and debris generated during the production of quartz stone are sucked away by the blower on the production equipment and introduced into the dust falling box 2 through the air inlet pipe 4. The dust first soaks in the dust falling liquid in the dust falling box 2. The dust or impurity particles are dissolved in water or sink in water. Start the motor 101 to drive the rotating shaft 611 and the grinding cone 612 below it to rotate, which can grind the large particles of quartz stone falling on the mesh plate 613 into small particles. The quartz stone that is small enough can pass through the mesh plate 613 to the lower side and flow into the water tank 3 through the connecting pipe 7 along with the water flow. Through the grinding of the grinding cone 612 and the mesh plate 613 on the quartz stone particles, the quartz stone can be ground into powder, which is convenient for subsequent extrusion and further processing of the quartz stone powder, ensures the uniform size, and also absorbs the iron filings and other impurities generated during the processing of the equipment. The initial state of the strip plate 614 is in an expanded state. When the dust is introduced into the liquid, the self-rotation of the rotating shaft 611 stirs the liquid, which can quickly mix the debris in the water. The iron filings and other impurities can be quickly absorbed by the magnetic strip 615 inside the strip plate 614, achieving the effect of separate collection of iron filings. After a period of time, when the strip plate 614 has enough iron filings to be cleaned, the collection mechanism can be driven. The limiting ring 131 moves down to store all the strip plates 614 in the assembly slot 121, isolating the internal space of the rotating shaft 611 from the dust falling liquid. In addition, after the end ring 132 is separated from the conductive ring 151, the power is cut off, the magnetic strip 615 inside the strip plate 614 loses its magnetism, and the iron filings on the magnetic strip 615 fall into the rotating shaft 611 for temporary storage. At this time, the driving motor 101 can be temporarily stopped, the air inlet end of the external blower is connected to the upper end of the rotating shaft 611, and the blower is started to suck out all the iron filings in the rotating shaft 611, achieving the effect of removing the iron filings without disassembly. The dust entering the dust falling box 2 is purified by the dust falling liquid and discharged from the air outlet pipe 5. The sewage containing particles enters the water tank 3. The water pump 812 located above the filter screen 811 pumps the water upwards. The sewage below the filter screen 811 is filtered by the filter screen 811. The quartz stone powder and impurities are left in the water tank 3 below the filter screen 811. The relatively pure dust falling liquid is recirculated to the dust falling box 2 through the conduit 813. When the water tank 3 has too many impurities at the bottom after a period of time, the air inlet can be stopped, and the inner sealing plate 172 and the outer sealing plate 171 are closed in advance to retain a portion of the dust falling liquid above the filter screen 811. Then the valve at the lower end of the water tank 3 is opened to discharge the impurities and dust falling liquid into the spiral extruder 9. The spiral extruder 9 can dehydrate and extrude a large amount of quartz stone powder. After the dust falling liquid in the water tank 3 is discharged, the inner sealing plate 172 is opened. The liquid above the inner sealing plate 172 quickly flows downward through the filter screen 811, which can clean the filter screen 811 and the residual powder on the inner wall of the lower end of the water tank 3. The water tank 3 is as clean as possible. Then add an appropriate amount of new dust falling liquid to the water tank 3, restart the water pump 812 and the motor 101, and continue to inject dust into the dust falling box 2 for a new round of dust washing.

[0033] It should be noted that the above examples are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced, without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
