Description

Technical Field

[0001] The invention relates to the technical field of dust collectors, in particular to a water-saving water bath dust collector. Background Art

[0002] The spray tower is a type of water bath dust collector, which removes dust and particulate matter in the air by spraying water mist. The water mist comes into contact with the dust particles, causing them to adhere to the surface of the water droplets, so that the dust falls to the bottom of the device along with the water mist. The treated air is directly discharged into the atmosphere through the discharge port at the upper end, thereby achieving the purpose of protecting the environment.

[0003] At present, the patent with announcement number CN112657298B discloses a high-efficiency spray tower, including a tower body, the bottom and top of the tower body are respectively provided with an air inlet and an exhaust port, the tower body is provided with a cyclone layer, a slow flow spray layer, an adsorption layer and a demisting layer, the cyclone layer, the slow flow spray layer, the adsorption layer and the demisting layer are arranged in sequence inside the tower body from bottom to top; the slow flow spray layer includes a slow flow layer plate and a first spray coil, the first spray coil is located below the slow flow layer plate, the slow flow layer plate includes multiple groups of slow flow plates and multiple groups of diverter plates, the diverter plate is located above the slow flow plate, the slow flow plate is annular, the cross-section of the slow flow plate is an inverted V-shape, the multiple groups of slow flow plates are coaxially arranged from the inside to the outside, and there is a gap between adjacent slow flow plates, the diverter plate is annular, the cross-section of the diverter plate is V-shaped, the multiple groups of diverter plates are coaxially arranged from the inside to the outside, and there is a gap between adjacent diverter plates. Through the obstruction of the buffer plate, the exhaust gas gathers under the buffer plate and blends with each other after flowing to the bottom of the slow flow plate, and then continues to flow upward from the gap between the buffer plates. After encountering the diverter plate, under the action of the diverter plate, it is diverted to both sides of the diverter plate and merges with another rising exhaust gas, so that the harmful substances in the exhaust gas can be evenly distributed, so that the spray solution can fully neutralize or absorb the harmful substances in the exhaust gas.

[0004] However, the following problems still exist in the current use of the spray tower:

[0005] When the above-mentioned device is in use, filler balls are arranged inside to increase the contact time between the gas and the spray water mist. The filler balls are usually made of vacuum ceramic material. As the gas treatment time increases, impurities and dust are easy to adhere to the surface of the filler balls, which causes the gaps between the fillers to become smaller, resulting in poor gas conduction effect. Therefore, the filler balls need to be removed and cleaned regularly and then put back into the device after cleaning, which is very time-consuming and labor-intensive. In addition, some stains are tightly attached to the outer surface of the filler balls, which may lead to incomplete cleaning, that is, it is easy to miss some filler balls during cleaning due to too many filler balls. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a water-saving water bath dust collector. The placement frame can be rotated to make the placement frame spherical, and then the packing balls can be turned over and cleaned, thereby ensuring that the packing balls are automatically and fully cleaned, thereby increasing the air conduction effect and service life of the packing balls.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See also Figure 1-Figure 10 The present invention provides a technical solution: a water-saving water bath dust collector, comprising a dust removal tower body 1, a water storage tank 2 is arranged at the lower end of the dust removal tower body 1, and a water guide pipe 4 is arranged on the water storage tank 2, a spray pipe 5 is fixedly installed on the water guide pipe 4, and the spray pipe 5 is installed on the inner surface of the dust removal tower body 1, a circulation pipe 3 is penetrated at the upper end of the water storage tank 2, and the circulation pipe 3 is penetrated at the lower end of the dust removal tower body 1, a filter plate is installed in a sleeve arranged at the connection between the water storage tank 2 and the circulation pipe 3, and a water pump is arranged on the circulation pipe 3, a filter plate for filtering sewage is arranged inside the water storage tank 2, a protective plate 18 is installed on the inner surface of the dust removal tower body 1, and an arc-shaped groove is opened on the protective plate 18, and the protective plate 18 and the rotating frame 8 are fitted with each other.

[0031] When it is necessary to clean the air containing dust or dust, the air containing dust can be introduced into the dust removal tower body 1 through the air inlet pipe at the lower end of the dust removal tower body 1, and then the spray pipe 5 starts to work (the spray pipe 5 starts to spray water mist). At this time, the spray pipe 5 starts to spray the air containing dust in the dust removal tower body 1, that is, the water mist starts to contact the dust in the air, and the weight of the dust starts to increase. At this time, the dust is separated from the air, and the separated dust falls into the lower end of the dust removal tower body 1 together with the water mist. Because filler balls are placed in the placement frame 7, the air can be blocked by the filler balls to achieve the purpose of air guidance (the gas is separated from the filler balls). The outer surface of the ball and the gap pass through), at this time, the contact time between air and water mist can be increased to ensure that the water mist and dust are in full contact, and the spray water containing dust enters the water tank 2 through the circulation pipe 3. Because the upper end of the water tank 2 is provided with a water pump and a filter plate, the water at the lower end of the dust removal tower body 1 can be sucked into the water tank 2 at this time, and is filtered before entering the water tank 2 (the filter plate can filter out the water-containing dust from the water), and the water entering the water tank 2 is introduced into the spray pipe 5 through the water guide pipe 4 for circulating spraying to achieve the purpose of water saving, and the dust-removed air is discharged into the atmosphere through the upper end of the dust removal tower body 1.

[0032] The dust removal tower body 1 is provided with a first support assembly 6 on the bearing installed at the upper end thereof, and a placement frame 7 is fixedly provided on the first support assembly 6, and a rotating frame 8 is fitted inside the placement frame 7, and a second support assembly 9 is provided on the bearing installed at the upper end of the dust removal tower body 1, a high-pressure water pipe 10 is fixedly installed on the rotating frame 8, and a flushing nozzle 11 is penetrated at the lower end of the high-pressure water pipe 10, a stamping assembly 12 is provided inside the high-pressure water pipe 10, and a return assembly 13 is provided on the stamping assembly 12, and a guide slide rod 1 is fixedly installed on the placement frame 7 4. A driving gear 15 is fixedly arranged on the first supporting assembly 6, and the driving gear 15 is meshed with the connecting rack 16, and the driving gear 15 is connected to the output end of the motor 17 through the rotating shaft, and the motor 17 is fixedly installed on the outer surface of the dust removal tower body 1; the first supporting assembly 6 includes a first sleeve 601, a connecting shaft 602 and a first limiting plate 603, and the first sleeve 601 is connected to the driving gear 15, and the first sleeve 601 forms a rotating mechanism with the dust removal tower body 1 through a bearing installed on the dust removal tower body 1, and the connecting shaft 602 is connected to the dust removal tower body 1 through a bearing installed on the dust removal tower body 1. The bearing and the first sleeve 601 form a rotating mechanism, the first limit plate 603 is fixedly mounted on the connecting shaft 602; the connecting shaft 602 is fixedly mounted on the placement frame 7, the first sleeve 601 is fixedly mounted on the rotating frame 8, and the first limit plate 603 is slidably connected to the first sleeve 601 through an annular groove provided on the first sleeve 601; a plurality of through holes are provided on the placement frame 7 and the rotating frame 8, and the inner surface of the placement frame 7 is tightly fitted with the outer surface of the rotating frame 8; the second supporting assembly 9 includes a second sleeve 901 and The second limit plate 902, and the second sleeve 901 form a rotating mechanism with the dust removal tower body 1 through the bearing installed on the dust removal tower body 1, the second limit plate 902 is slidably connected with the second sleeve 901 through the annular groove opened on the second sleeve 901, the second limit plate 902 is installed on the outer surface of the high-pressure water pipe 10, and the high-pressure water pipe 10 is tightly fitted with the inner surface of the second sleeve 901; the outer surface of the guide slide rod 14 is set to be smooth, and the guide slide rod 14 is slidably connected with the rotating frame 8 through the through arc groove opened on the rotating frame 8.

[0033] When the filling balls need to be cleaned, the motor 17 starts to work, because the output end of the motor 17 is connected to the driving gear 15 through the rotating shaft (two driving gears 15 are provided, and the two driving gears 15 are meshed and connected with the connecting rack 16. At this time, the two driving gears 15 can be driven to rotate synchronously under the action of the connecting rack 16), and because the driving gear 15 is connected to the first sleeve 601, the first sleeve 601 starts to rotate. Because the first sleeve 601 is installed on the rotating frame 8, the rotating frame 8 also starts to rotate (the rotating frame 8 and the rotating frame 8 are connected). Although the placement frame 7 is rotatably connected, a large number of ceramic filler balls are placed in the placement frame 7. At this time, under the action of the gravity of the filler balls, the placement frame 7 will not rotate with the rotating frame 8), until the rotating frame 8 rotates to a position misaligned with the placement frame 7. At this time, the holes opened on the placement frame 7 are misaligned with the holes opened on the rotating frame 8, that is, the purpose of blocking the holes opened on the placement frame 7 is achieved, and then water containing a cleaning agent is sprayed into the placement frame 7 through a high-pressure water pipe 10, so as to achieve the purpose of soaking the filler balls in the placement frame 7, thereby softening the filler balls. The stubborn stains attached to the surface are convenient for subsequent cleaning. After soaking for a certain period of time, the motor 17 continues to work (the motor 17 is set as a servo motor with a self-locking function that can rotate forward and backward). At this time, the rotating frame 8 continues to rotate, that is, the guide slide bar 14 installed on the placement frame 7 begins to fit with the arc groove opened on the rotating frame 8, until the rotating frame 8 rotates a total of 180°. At this time, the guide slide bar 14 begins to fit closely with the rotating frame 8. As the first sleeve 601 continues to rotate, the rotating frame 8 interconnected with the first sleeve 601 begins to drive the placement frame 7 to rotate. Rotate (after the rotating frame 8 rotates 180°, under the action of the guide slide bar 14, as the rotating frame 8 continues to rotate, the rotating frame 8 begins to drive the placement frame 7 connected to the guide slide bar 14 to rotate together), at this time, the filler balls placed in the placement frame 7 can be turned over, and then the high-pressure water pipe 10 starts to supply water (the high-pressure water pipe 10 is connected to an external water supply tank, and a high-pressure water pump is provided in the water supply tank to provide high-pressure water to the high-pressure water pipe 10), so that the filler balls can be high-pressure washed, effectively ensuring that the filler balls are fully and evenly washed.

[0034] The return assembly 13 includes a guide rod 131 and a return spring 132. The guide rod 131 is fixedly mounted on the inner surface of the high-pressure water pipe 10, and the return spring 132 is fixedly mounted on the high-pressure water pipe 10. The stamping assembly 12 includes a positioning plate 121 and a push plate 122. The upper end of the push plate 122 is connected to the return spring 132, and the guide rod 131 is slidably connected to the push plate 122 through a groove provided on the push plate 122. The positioning plate 121 is fixedly mounted on the push plate 122.

[0035] After the rotating frame 8 rotates 180°, the high-pressure water pipe 10 starts to supply water. A rotating joint is provided in the middle position of the high-pressure water pipe 10 to ensure that the end connected to the water supply tank is fixed and the end extending into the dust removal tower body 1 is rotating (the rotating joint is an existing structure at this time). At this time, as the placement frame 7 and the rotating frame 8 rotate, the high-pressure water pipe 10 extending into the dust removal tower body 1 also starts to rotate. As water is supplied to the high-pressure water pipe 10, the high-pressure water begins to impact the push plate 122, and the push plate 122 begins to move toward the direction close to the inner wall of the high-pressure water pipe 10, that is, the push plate 122 begins to slide along the guide rod 131, and the return spring 132 installed on the push plate 122 begins to be squeezed and deformed. Because the push plate 122 is installed with a positioning plate 121, the high-pressure water pipe 10 and the second sleeve 901 can be clamped and fixed through the positioning plate 121, and because the second sleeve 901 is fixedly connected to the rotating frame 8, the high-pressure water pipe 10 The rotating frame 8 is fixedly connected to the placement frame 7, and the placement frame 7 and the rotating frame 8 can be engaged and fixed at this time to avoid the gap between the rotating frame 8 and the placement frame 7 during the subsequent rotation process, which may cause the packing balls to fall out. When the cleaning is completed, the high-pressure water pipe 10 stops supplying water. At this time, under the action of the return spring 132 restoring the deformation, the return spring 132 begins to push the push plate 122 to move away from the high-pressure water pipe 10. At this time, the positioning plate 121 is no longer in contact with the groove opened on the second sleeve 901, thereby releasing the limit between the second sleeve 901 and the high-pressure water pipe 10, and then the motor 17 drives the driving gear 15 to reverse (that is, rotate in the opposite direction to the above process). At this time, the rotating frame 8 rotates in the direction close to the placement frame 7 until it rotates to fit tightly with the lower end of the placement frame 7, and the holes opened on the placement frame 7 and the holes opened on the rotating frame 8 are all on the same vertical line, completing the cleaning of the packing balls.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
