Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning devices, and in particular relates to a water-saving and high-efficiency double-sided mud and sand cleaning device for granite slabs. Background Art

[0002] Stone slabs are widely used in construction, decoration and other fields due to their excellent physical and chemical properties. The rapid development of the stone industry has greatly promoted the prosperity of stone processing machinery in my country. After the shape of the granite slab is processed, the sand saw will leave some lime and steel sand on its surface. If the lime and steel sand attached to the surface of the stone slab are not cleaned and removed in time, it will cause serious corrosion and rust on the surface of the stone slab, seriously affecting the appearance of the stone slab, and then reducing the use value of the stone slab. Therefore, after the stone slab is cut, it must be cleaned to remove the impurities remaining during the cutting process.

[0003] Nowadays, the slab cleaning process of most granite slab production enterprises mainly relies on manual work, which can basically meet the production needs of enterprises, but there are still certain problems. The specific problems are as follows: (1) The manual cleaning method is generally for workers to spray the stone slabs with high-pressure water guns, which consumes a lot of water;

[0004] (2) Manual cleaning will generate a large amount of cleaning waste liquid, which is not conducive to factory cleaning;

[0005] (3) Manual cleaning generally leaves a large amount of residual moisture on the surface of the stone slab after cleaning, which is not conducive to the rapid drying of the stone slab;

[0006] (4) Manual cleaning methods generally require a large number of stone slabs to be placed vertically with the aid of support frames, which requires a large amount of factory space. Utility Model Content

[0014] Preferably, the water removal mechanism includes a water removal roller installed behind the water spray pipe, a scraper installed behind the water removal roller, a water removal cross bar connecting the frame and the water removal roller, an air cooler, a wind hood installed at the air outlet of the air cooler, and a fan mounting base for connecting the air cooler and the frame.

[0015] Preferably, the dewatering cross bar is connected to dewatering screws installed vertically on both sides, and the dewatering screws can control the up and down heights of the dewatering rollers.

[0016] Preferably, the wiper is made of rubber, and is vertically fixed to the front end of the fan mounting seat, and the distance between the bottom edge and the upper side of the roller assembly is less than the minimum thickness of the stone slab.

[0017] Preferably, the cooling fan is connected to the frame via a fan mounting base, the opening direction of the air cover faces directly downward, and its width is the same as the length of the roller in the roller group.

[0018] Preferably, a filter screen is provided on the upper portion of the water tank, a plurality of drainage plates in different directions are provided inside the water tank, and the water tank and the drainage plates are connected by welding.

[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0020] 1. In this application, the staff places the stone slab on the roller assembly, and the roller assembly transports the stone slab into the cleaning box for cleaning. For the same batch of stone slabs of the same specifications, the staff can first control the small motor to drive the cleaning screw and the cleaning nut through the control panel, so that the adjustment cross bar connected to the cleaning nut drives the upper brush roller to move in the vertical direction to achieve the best cleaning height. After the stone slab is cleaned, the staff can drive the dewatering cross bar to move in the vertical direction through the dewatering screw to ensure that the dewatering roller can contact the upper surface of the stone slab but will not stop the horizontal movement of the stone slab on the roller assembly. Finally, the scraper and the cold air fan remove the residual moisture on the surface of the stone slab to complete the surface cleaning and preliminary drying of the stone slab. After the above-mentioned mechanism is adjusted, the device can automatically clean the subsequent stone slabs.

[0021] In order to enable the upper brush roller and the lower brush roller to freely adjust the rotation speed according to demand, the upper brush roller and the lower brush roller are driven by independent motors, and the motor is connected to the upper brush roller and the lower brush roller through a chain drive.

[0022] Furthermore, the granite slabs are transported to the interior of the cleaning device through a roller assembly, and the cleaning device can be subsequently connected to a drying device, etc. The water tank can collect the cleaning liquid generated during the cleaning process and recycle the collected cleaning liquid through a self-priming pump. The water in the water tank is pumped into the sprinkler pipe through the self-priming pump, and then multiple streams of water are sprayed obliquely upward from several circular holes arranged side by side on the sprinkler pipe; the upper brush roller is connected to the adjustment cross bar, and the vertical spacing between the upper brush roller and the roller assembly can be adjusted by controlling the pitch angle of the adjustment cross bar through the control knob.

[0023] The dewatering roller and the wiper can remove most of the water remaining on the surface of the stone slab after cleaning. Then the wind hood will direct the air from the air cooler to the surface of the stone slab to remove the remaining water.

[0024] 2. As a preferred embodiment of the utility model, the cleaning mechanism also includes cleaning columns installed on both sides of the frame, cleaning upper brackets and adjustment cross bars installed on the cleaning columns, the water spray pipe and the upper brush roller are installed on the adjustment cross bar, the roller diameter of the upper brush roller is slightly larger than the diameter of the roller in the roller group, the two lower brush rollers replace the two rollers in the roller group located directly below the upper brush roller, and the roller diameter of the two lower brush rollers is slightly smaller than the diameter of the roller in the roller group. The slightly smaller diameter of the lower brush roller can reduce the damage of the brush roller to the stone slab during transportation.

[0025] The sprinkler pipe is provided with several water outlets in the same row. When installed, the water outlets face obliquely upward. The sprinkler pipe is connected to the self-priming pump through a water pipe. The self-priming pump is connected to the water tank. The cleaning tank is directly above the water tank. The cleaning tank has no bottom plate and the water tank has no upper cover, so that the cleaning water can enter the water tank without splashing, thereby reducing the waste of water resources and keeping the device installation area in the factory clean.

[0026] Most of the cleaning water during the cleaning process will fall directly into the water storage tank, and a small amount of cleaning water splashed onto the cleaning tank will slide along the inner wall of the cleaning tank into the water storage tank, or evaporate during the sliding process, which can ensure that no cleaning water will splash out of the device.

[0027] 3. As a preferred embodiment of the utility model, the cleaning mechanism also includes a motor installed on the cleaning upper bracket, which is connected to the upper brush roller and the lower brush roller through a chain drive, and independently drives the upper brush roller connection and the lower brush roller to rotate, and the roller shaft group shares another drive system. The independent drive system allows the device to independently adjust the rotation speed of the upper brush roller connection and the lower brush roller and the transportation speed of the roller shaft group according to actual production needs.

[0028] 4. As a preferred embodiment of the utility model, the adjustment crossbar is connected to a cleaning screw rod vertically mounted on the cleaning upper bracket through a cleaning nut, and the cleaning screw rod is driven by a small motor, which is connected to the device control system. The device can freely adjust its height according to the thickness of the stone slab to be cleaned, meeting the cleaning needs of stone slabs of various thicknesses.

[0029] By adjusting the cross bar, the upper brush roller and the stone slab to be cleaned are at a suitable relative height, which can ensure that only an appropriate amount of brush wire on the upper brush roller and the lower brush roller contacts the stone slab, while the metal shaft of the brush roller itself does not contact, thereby extending the service life of the brush roller.

[0030] 5. As a preferred embodiment of the utility model, the water removal mechanism includes a water removal roller installed behind the water spray pipe, a water scraper installed behind the water removal roller, a water removal cross bar connecting the frame and the water removal roller, a cold air fan, a wind cover installed at the air outlet of the cold air fan, and a fan mounting seat for connecting the cold air fan and the frame. The three water removal steps can remove most of the residual water on the surface of the stone slab after cleaning, so as to speed up the subsequent stone slab drying process.

[0031] After the stone slab has gone through the above-mentioned water removal process, it can be ensured that there is no flowing water on the surface of the stone slab, and only the water that has penetrated into the interior of the stone slab still needs to be dried.

[0032] Furthermore, the dewatering cross bar is connected to two dewatering screws installed in the vertical direction on both sides, and the up and down heights of the dewatering rollers can be controlled by the dewatering screws to meet the dewatering needs of stone slabs of various thicknesses.

[0033] Furthermore, the wiper is made of rubber and is vertically fixed to the front end of the fan mounting base, and the distance between the bottom edge and the upper side of the roller assembly is less than the minimum thickness of the stone plate, which can ensure that the wiper can always generate friction with the surface of the stone plate.

[0034] The scraper blade can always have a contact portion with the upper surface of the stone plate at least 2cm from the lower boundary. Since the scraper blade is made of rubber and the transportation speed of the stone plate is generally not more than 2m / min, the contact process will not cause damage to the surface of the stone plate or slow down the transportation speed of the stone plate.

[0035] 6. As a preferred embodiment of the utility model, the air cooler is connected to the frame through the fan mounting base, the opening direction of the air cover is facing directly downward, and its width is the same as the length of the roller in the roller group, so as to control the flow direction of the cold air and ensure that all stone slabs passing under the air cooler can receive the cold air.

[0036] Preferably, the filter screen can be installed on the upper edge of the water tank according to actual needs to reduce the sediment content in the cleaning water and prevent the sediment from clogging the water pipe. Several drainage plates in different directions are provided inside the water tank, and the water tank and the drainage plates are connected by welding. The drainage plate can direct the cleaning water to the outlet on one side of the bottom of the water tank in a direction to ensure that the flow direction of the cleaning water is not affected by the uneven ground where the device is installed. The water tank is only placed on the bottom crossbar of the device frame, and there is no other form of connection between it and the frame, which is convenient for disassembly, cleaning and maintenance of the water tank.

The cleaning mechanism includes a watering pipe 7 connected to a water delivery pipe and a self-priming pump, an upper brush roller 6 with an adjustable height located below the watering pipe 7, and two lower brush rollers 14 installed between roller shafts. The water in the water storage tank 25 is pumped into the watering pipe 7 by the self-priming pump, and then multiple streams of water are sprayed obliquely upward from several circular holes arranged side by side on the watering pipe 7; the upper brush roller 6 is connected to an adjustment crossbar 8, and the vertical spacing between the upper brush roller 6 and the roller shaft group 1 can be adjusted by controlling the pitch angle of the adjustment crossbar 8 by controlling the knob. The dewatering mechanism mainly includes a dewatering roller 16, a wiper 21, a dewatering crossbar 5 for connecting and driving the dewatering roller 16, a cold air machine 4, and a wind hood 2 installed at the air outlet of the cold air machine 4. The dewatering roller 16 and the wiper 21 can remove most of the water remaining on the surface of the stone plate component 20 after cleaning. Then, the wind hood 2 guides the air blown out by the cold air machine 4 to the surface of the stone plate to remove the remaining water.

[0052] In one embodiment, the staff places the stone plate component 20 on the roller assembly 1, and the roller assembly 1 transports the stone plate component 20 into the cleaning box 26 for cleaning. For the stone plate components 20 of the same batch and the same specifications, the staff can first control the small motor 9 through the control panel to drive the cleaning screw 23 and the cleaning nut 24, so that the adjustment cross bar 8 connected to the cleaning nut 24 drives the upper brush roller 6 to move in the vertical direction to achieve the best cleaning height. After the stone plate component 20 is cleaned, the staff can drive the dewatering cross bar 5 to move in the vertical direction through the dewatering screw 15 to ensure that the dewatering roller 16 can contact the upper surface of the stone plate component 20 but will not stop the horizontal movement of the stone plate component 20 on the roller assembly 1. Finally, the scraper 21 and the cold air blower 4 remove the residual moisture on the surface of the stone plate component 20 to complete the surface cleaning and preliminary drying of the stone plate component 20. After the above mechanism is adjusted, the device can automatically clean the subsequent stone plate components 20.

[0053] In order to enable the upper brush roller 6 and the lower brush roller 14 to freely adjust the rotation speed according to demand, the upper brush roller 6 and the lower brush roller 14 are driven by independent motors 10, and the motor 10 is connected to the upper brush roller 6 and the lower brush roller 14 through a first chain drive 11.

The slightly smaller diameter of the lower brush roller 14 can reduce the damage of the brush roller to the stone slab during transportation.

[0055] Preferably, the water spray pipe 7 is provided with several water outlets in the same row. When installed, the water outlets face obliquely upward. The water spray pipe 7 is connected to the self-priming pump through a water pipe, and the self-priming pump is connected to the water storage tank 25. Directly above the water storage tank 25 is a cleaning tank 26. The cleaning tank 26 has no bottom plate, and the water storage tank 25 has no upper cover, so that the cleaning water can enter the water storage tank 25 without splashing, thereby reducing the waste of water resources and keeping the device installation area in the factory clean.

[0056] In one embodiment, most of the cleaning water during the cleaning process will fall directly into the water tank 25, and a small amount of cleaning water splashed onto the cleaning box 26 will slide along the inner wall of the cleaning box 26 into the water tank 25, or evaporate during the sliding process, thereby ensuring that no cleaning water will splash out of the device.

[0057] Preferably, the cleaning mechanism further includes a motor 10 mounted on the cleaning upper bracket 13, the motor 10 is connected to the upper brush roller 6 and the lower brush roller 14 through the first chain drive 11, and independently drives the upper brush roller 6 and the lower brush roller 14 to rotate, and the roller group 1 shares another drive system, and the drive system includes a second chain drive 19. The independent drive system allows the device to independently adjust the rotation speed of the upper brush roller 6 and the lower brush roller 14 and the transportation speed of the roller group 1 according to actual production needs.

[0058] It should also be noted that a motor mounting base 22 for mounting the motor 10 is also included to eliminate vibration of the motor 10 in a working state and make the motor 10 run more smoothly.

The device can freely adjust its height according to the thickness of the stone plate component 20 to be cleaned, meeting the cleaning requirements of stone plate components 20 of various thicknesses.

[0060] In one embodiment, by adjusting the cross bar 8, the upper brush roller 6 and the stone slab component 20 to be cleaned are at a suitable relative height, which can ensure that only an appropriate amount of brush wires of the upper brush roller 6 and the lower brush roller 14 contact the stone slab component 20, while the metal shaft of the brush roller itself does not contact, thereby extending the service life of the brush roller.

[0061] Preferably, the water removal mechanism includes a water removal roller 16 installed behind the water spray pipe 7, a water scraper 21 installed behind the water removal roller 16, a water removal cross bar 5 connecting the frame 17 and the water removal roller 16, a cold air fan 4, a wind cover 2 installed at the air outlet of the cold air fan 4, and a fan mounting seat 3 for connecting the cold air fan 4 and the frame 17.

[0065] In one embodiment, the wiper blade 21 can always have a contact portion at least 2 cm long from the lower boundary with the upper surface of the stone plate component 20. Since the wiper blade 21 is made of rubber and the transportation speed of the stone plate component 20 is generally not more than 2 m / min, the surface of the stone plate component 20 will not be damaged or the transportation speed of the stone plate component 20 will not be slowed down during the contact process.

[0066] Preferably, the air cooler 4 is connected to the frame 17 via the fan mounting base 3, the opening direction of the air cover 2 is facing directly downward, and its width is the same as the length of the roller in the roller group 1, so as to control the flow direction of the cold air and ensure that all stone slab components 20 passing under the air cooler 4 can receive the cold air.
