Description

Technical Field

[0001] The present application relates to the technical field of oily wastewater treatment, and particularly to a cleaning device for a sponge conveyor belt. Background Art

[0002] In the treatment of some oily wastewater, it is usually necessary to separate oil and water from the wastewater, and then perform subsequent treatment processes on the wastewater to meet the discharge standards or for reuse. As a lifting structure, the conveyor belt has also gradually been applied in the treatment of oily wastewater.

[0003] The conveyor belt in oily wastewater treatment is usually made of hydrophobic and lipophilic sponge material. The conveyor belt is inclined and extends into the wastewater. The conveyor belt can adsorb the oil in the wastewater. The upper end of the conveyor belt is squeezed by a squeezing roller. During the continuous movement of the conveyor belt, the oil is continuously adsorbed and then squeezed out by the squeezing roller, thereby cleaning the conveyor belt and enabling the conveyor belt to repeatedly remove oil from the wastewater.

[0004] However, the wastewater contains impurities such as oil, oil suspensions, and scum. When the conveyor belt moves, these substances can also be carried out. The hydrophobic and lipophilic sponge material usually has a porous structure. When directly squeezing the conveyor belt by the squeezing roller, some solid particles are easily blocked in the pores of the conveyor belt, resulting in a relatively rapid decline in the oil absorption capacity of the conveyor belt, thereby affecting the oil removal efficiency of the wastewater. Summary of the Invention

[0005] In order to improve the cleaning effect of the conveyor belt made of sponge material, the present application provides a cleaning device for a sponge conveyor belt.

[0006] The present application adopts the following technical solutions:

[0007] A cleaning device for a sponge conveyor belt includes a cleaning roller set and a squeezing roller set; the cleaning roller set includes a bracket, a blowing component installed on the bracket, and a scraping roller rotatably connected to the bracket. Brush hairs are uniformly arranged on the outer wall of the scraping roller; the blowing component includes a blowing pipe arranged on the bracket, a rotating cylinder rotatably connected to the outer wall of the blowing pipe, and a gas source connected to the blowing pipe; blowing holes are spaced apart along the axis direction of the blowing pipe on the outer wall of the blowing pipe, and yielding holes are spaced apart on the outer wall of the rotating cylinder. A driving member is arranged on the bracket for driving the rotating cylinder and the scraping roller to rotate; the conveyor belt passes between the rotating cylinder and the scraping roller and then enters the squeezing roller set, and the rotating directions of the rotating cylinder and the scraping roller are opposite. When the rotating cylinder rotates, the yielding holes can coincide with the blowing holes, and at this time the conveyor belt can cover the yielding holes.

[0008] By adopting the above technical solution, the conveyor belt passes between the rotating drum and the scraper roller. When the rotating drum rotates, the blowing hole and the giving hole coincide. Since the conveyor belt is made of porous sponge material, the conveyor belt abuts against the surface of the rotating drum. The gas can run into the conveyor belt and drive the oil and water to seep out of it, and carry the impurities in the surface pores to the surface of the conveyor belt. The scraper roller surface has bristles, and the scraper roller and the rotating drum rotate in opposite directions, that is, the impurities on the surface of the conveyor belt can be scraped off, and then enter the extrusion roller group for extrusion and oil removal.

[0009] Optionally, an auxiliary roller is rotatably mounted on the bracket, and the auxiliary roller can rotate synchronously with the rotating drum. The auxiliary roller and the rotating axis of the rotating drum are parallel, and an abutment plate is connected to the side wall of the auxiliary roller in a radial sliding manner along the auxiliary roller. An elastic member is installed on the auxiliary drum, and when the auxiliary roller rotates, the elastic member is used to drive the abutment plate to abut against the conveyor belt so that the conveyor belt abuts against the rotating drum.

[0010] By adopting the above technical solution, when the auxiliary roller rotates, the abutment plate can drive the conveyor belt to abut against the rotating drum, so that when the air pipe is blowing, the gas can better blow the conveyor belt abutting against the surface of the rotating drum, so that the gas can better pass through the conveyor belt to drive impurities to move to the surface of the conveyor belt.

[0011] Optionally, a sliding groove is provided on the outer wall of the auxiliary roller, the abutment plate is slidably connected to the sliding groove, and the elastic member includes a spring installed in the sliding groove, and the spring is compressed when the abutment plate abuts against the rotating cylinder.

[0012] By adopting the above technical solution, the abutment plate can be pressed tightly against the rotating drum under the elastic force of the spring, thereby providing a sealing effect for the conveyor belt.

[0013] Optionally, a contact plate is slidably provided on the outer wall of the scraper roller, and a driving source is installed on the contact plate scraper roller, and the driving source is used to provide elastic force for the contact plate to abut against the rotating cylinder. A linkage is provided between the bracket and the contact plate, and when the contact plate abuts against the rotating cylinder, the contact plate also abuts against the rotating cylinder. When the contact plate rotates away from the rotating cylinder, the contact plate is received in the scraper roller through the linkage, so that the height of the contact plate protruding from the surface of the scraper roller is less than the length of the bristles.

[0014] By adopting the above technical solution, under the action of the driving source and the linkage, the contact plate can abut against the rotating drum, so that under the pressing action of the abutment plate and the contact plate, the conveyor belt is pressed against the rotating drum, thereby improving the air tightness and allowing the gas to better enter the conveyor belt.

[0015] Optionally, a receiving groove is provided on the surface of the scraper roller, and the linkage part includes a circular ring arranged on the bracket and an extension rod connected to two ends of the contact plate, and a step edge is provided on the inner wall of the circular ring, and the inner wall of the circular ring includes an arc segment connected to the end of the step edge away from the center of the circular ring and an inclined surface segment connected to the end of the step edge close to the center of the circular ring. Under the action of the driving source, when the scraper roller rotates, the extension rod abuts against the inner wall of the circular ring, and when the extension rod moves to the step edge, the driving source drives one end of the contact plate to abut against the rotating drum, and when the extension rod moves on the inclined surface segment, the contact plate can move into the receiving groove.

[0016] By adopting the above technical solution, the scraper roller and the conveyor belt have opposite movement directions. When the extension rod moves to the step edge, the contact plate can abut against the rotating drum under the action of the driving source. When the extension rod moves on the inclined surface section, the contact plate can be pressed by the inclined surface section and slide into the accommodating groove.

[0017] Optionally, the contact plate and the contact plate are both provided with chamfers at one end close to the rotating cylinder.

[0018] By adopting the above technical solution, the possibility of scratching the conveyor belt is reduced.

[0019] Optionally, the air source includes a connecting pipe connected to the air blowing pipe and a fan connected to the connecting pipe.

[0020] Optionally, the squeezing roller group includes two rollers arranged one above the other, and the conveyor belt passes between the two rollers.

[0021] By adopting the above technical solution, the roller rotates to squeeze the conveyor belt to squeeze out the oil and water.

[0022] In summary, the present application includes at least one of the following beneficial effects:

[0023] 1. The conveyor belt abuts against the surface of the drum. When the blowing hole and the clearance hole coincide, the conveyor belt can be blown, so that the foreign particles in the conveyor belt are blown to the surface of the conveyor belt, and then cleaned by the bristles on the surface of the scraper roller;

[0024] 2. Under the action of the contact plate and the abutment plate, the sealing between the conveyor belt and the rotating drum can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following is combined with Figures 1-5 This application is described in further detail.

[0032] The present application embodiment discloses a sponge conveyor belt 19 cleaning device. Figure 1 The cleaning device is used to clean the conveyor belt 19 made of sponge material. The conveyor belt 19 is usually made of oleophilic and hydrophobic sponge material. The conveyor belt 19 extends obliquely in the oily wastewater and is driven by roller transmission. The conveyor belt 19 can absorb the grease. The cleaning device is located at the upper end of the conveyor belt 19 and is used to remove grease and impurities from the conveyor belt 19, so that the conveyor belt 19 can continuously remove oil from the wastewater.

[0033] Reference Figure 2 The cleaning device includes a cleaning roller group 2 and a squeezing roller group 1. The conveyor belt 19 first passes through the cleaning roller group 2 and then enters the squeezing roller group 1.

[0034] The cleaning roller set 2 includes a bracket 21, a blowing component 22 mounted on the bracket 21, and a scraping roller 23 rotatably connected to the bracket 21. The blowing component 22 includes a blowing pipe 221 mounted on the bracket 21, a gas source 223 connected to the blowing pipe 221, and a rotating cylinder 222 rotatably connected to the outer wall of the blowing pipe 221. The conveyor belt 19 is wound around the rotating cylinder 222 and passes through the space between the rotating cylinder 222 and the scraping roller 23. Brush hairs 3 are evenly connected to the side wall of the scraping roller 23. A driving member 5 for driving the rotation of the rotating cylinder 222 and the scraping roller 23 is mounted on the bracket 21. The driving member 5 can be a motor. The end faces of the rotating cylinder 222 and the scraping roller 23 are coaxially fixed with a rotating shaft, and the rotating shaft is rotatably connected to the bracket 21 through bearings or the like and is connected to the output shaft of the motor, so as to drive the rotation of the rotating cylinder 222 and the scraping roller 23. The scraping roller 23 is located below the rotating cylinder 222, and the rotating directions of the rotating cylinder 222 and the scraping roller 23 are opposite, so that the brush hairs 3 can scrape off the impurities on the surface of the conveyor belt 19 and then enter the squeezing roller set 1.

[0035] Referring to Figure 2 and Figure 3 , air blowing holes 6 are formed in the side wall of the blowing pipe 221, and the air blowing holes 6 are arranged at intervals along the axial direction of the blowing pipe 221. Yielding holes 4 are formed in the outer wall of the rotating cylinder 222, and the yielding holes 4 correspond to the air blowing holes 6 one by one, so that when the rotating cylinder 222 rotates, the yielding holes 4 can coincide with the air blowing holes 6. The gas source 223 includes a connecting pipe 2231 connected to a trachea and a blower 2232 connected to the connecting pipe 2231. The blower 2232 is used to supply air into the blowing pipe 221. The conveyor belt 19 abuts against the surface of the rotating cylinder 222. When the rotating cylinder 222 rotates, the conveyor belt 19 covers the yielding holes 4, and when the air blowing holes 6 and the yielding holes 4 coincide, the gas enters the conveyor belt 19 and runs out from the surface of the conveyor belt 19. The conveyor belt 19 made of sponge material is a porous structure, so that there are more particulate impurities in the pores on the surface of the conveyor belt 19. During the movement of the gas, it can promote the seepage of oil and water from the surface of the conveyor belt 19, and drive the particulate impurities to fall or move to the surface of the conveyor belt 19 from the pores, and then be cleaned by the brush hairs 3.

[0036] Referring to Figure 2 and Figure 4, an auxiliary roller 7 is also rotatably mounted on the bracket 21, and the auxiliary roller 7 is arranged in parallel with the rotating drum 222. A motor is also mounted on the bracket 21, and the auxiliary roller 7 is driven to rotate by the motor, and the rotation direction of the rotating drum 222 is opposite to the rotation direction of the auxiliary drum. A sliding groove 10 is provided on the side wall of the auxiliary roller 7, and a contact plate 8 is slidably connected in the sliding groove 10, and the contact plate 8 slides along the radial direction of the auxiliary roller 7. An elastic member 9 is also installed in the sliding groove 10, and the elastic member 9 is a spring, one end of the spring is connected to the contact plate 8, and the other end is connected to the inner end surface of the sliding groove 10, and multiple springs can be installed. When the auxiliary roller 7 moves to the position of the rotating drum 222, the contact plate 8 can contact the rotating drum 222, so that the conveyor belt 19 can be driven to contact the surface of the rotating drum 222, and the contact plate 8 can slide into the sliding groove 10, and the elastic member 9 is compressed. The abutment plate 8 abuts against the conveyor belt 19 , thereby improving the sealing performance when the conveyor belt 19 and the rotating drum 222 abut against each other and increasing the amount of gas entering the conveyor belt 19 .

[0037] Reference Figure 2 and Figure 5 The outer wall of the scraper roller 23 is provided with a receiving groove 14, in which a contact plate 11 is slidably installed, and a driving source 12 is also installed in the receiving groove 14. The driving source 12 is a spring, and a plurality of springs can be connected. Under the elastic force of the spring, the contact plate 11 can contact the rotating drum 222. A linkage 13 is installed between the bracket 21 and the contact plate 11. When the scraper roller 23 rotates, the receiving groove 14 faces the rotating drum 222, and the driving source 12 can drive the contact plate 11 to contact the rotating drum 222, so that the conveyor belt 19 is pressed against the rotating drum 222. The scraper roller 23 continues to rotate. Under the action of the linkage 13, the contact plate 11 can move into the receiving groove 14, and the driving source 12 is compressed. When the contact plate 11 slides into the receiving groove 14, the distance from the end face of the contact plate 11 to the surface of the scraper roller 23 is less than the length of the bristles 3. When the abutment plate 8 is pressed against the drum 222, the abutment plate 11 is also pressed against the drum 222, so that the abutment plate 8 and the abutment plate 11 can better seal the transmission belt, and the gas can better enter the conveyor belt 19. The ends of the abutment plate 8 and the abutment plate 11 that abut against the conveyor belt 19 are chamfered to reduce friction.

[0038] The linkage member 13 includes a circular ring 131 fixed on the bracket 21 and an extension rod 132 fixed on both ends of the abutment plate 11, and the extension rod 132 extends into the inner cavity of the adjacent circular ring 131. A step edge 15 is provided on the inner wall of the circular ring 131, and the step edge 15 extends in the radial direction of the circular ring 131. The inner wall of the circular ring 131 includes an arc segment 16 and a slope segment 17, the arc segment 16 is connected to the end of the step edge 15 away from the center of the circular ring 131, the slope segment 17 is connected to the end of the step edge 15 close to the center of the circular ring 131, and the arc segment 16 is connected to the end of the slope segment 17 away from the step edge 15. When the scraper roller 23 rotates, the extension rod 132 abuts against the inner wall of the circular ring 131, that is, it is located on the circular arc segment 16 and the slope segment 17, and the driving source 12 is in a compressed state when it is located on the slope segment 17. When the movement reaches the position of the step edge 15, the driving source 12 pops up to drive the contact plate 11 to slide and the extension rod 132 to contact the arc segment 16. The scraping roller 23 continues to rotate, and the extension rod 132 moves on the inclined surface segment 17, so that the contact rod gradually slides into the receiving groove 14. Since the scraping roller 23 and the rotating drum 222 rotate in opposite directions, under the action of the linkage 13 and the driving source 12, the contact plate 11 is not easy to scratch the conveyor belt 19.

[0039] Reference Figure 2 The squeezing roller set 1 includes rollers 102 arranged in an upper and lower position, the rollers 102 are connected by a mounting seat, etc., the conveyor belt 19 passes between the two rollers 102, and the two rollers 102 are driven to rotate by a motor. The gap between the two rollers 102 is smaller than the thickness of the conveyor belt 19, so that the rollers 102 can squeeze the conveyor belt 19 and squeeze out the oil and water in the conveyor belt 19. Multiple groups of squeezing roller sets 1 can be set in the moving direction of the conveyor belt 19 as needed.

[0040] The implementation principle of a sponge conveyor belt 19 cleaning device in an embodiment of the present application is as follows: the conveyor belt 19 passes between the rotating drum 222 and the scraper roller 23 and then enters the extrusion roller group 1. When the abutment plate 8 and the contact plate 11 abut against the rotating drum 222, the blowing hole 6 and the giving way hole 4 can overlap, so that gas can enter the conveyor belt 19 and be discharged from the end of the conveyor belt 19 away from the rotating drum 222, thereby bringing out impurities in the pores or driving impurities in the pores to the surface of the conveyor belt 19, and then the surface of the conveyor belt 19 is scraped by the bristles 3.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
