Description

Technical Field

[0001] This utility model relates to the field of environmental protection denitrification technology, specifically to an environmental protection denitrification spray device. Background Technology

[0002] Environmental denitrification refers to the process of removing nitrogen oxides from waste gas. It is an important part of air pollution prevention and control. Currently, with the increasing awareness of environmental protection, denitrification technology has been widely used and developed in many industries.

[0003] For example, the utility model with announcement number CN220677351U discloses an environmentally friendly denitrification spray device, which is applied in the field of denitrification spray devices. It includes a spray tank, an air inlet seat is installed on one side of the spray tank by a fixing component, an air inlet pipe is connected to one side of the air inlet seat, an air outlet pipe connected to the air inlet seat is installed inside the spray tank, and a slot is opened on one side of the air inlet seat, and a filter seat is engaged inside the slot. The utility model has a slot opened inside the air inlet seat, and a filter seat is engaged inside the slot. A filter screen is installed inside the filter seat. When external flue gas enters the air inlet seat, it can filter out the dust particles in the flue gas, preventing the dust particles from mixing with the spray liquid and clogging the spray head during spraying, ensuring the normal operation of the spraying work. When the bolts on the sealing plate are removed, the filter seat can be quickly taken out and the filter screen can be cleaned, reducing the difficulty of cleaning.

[0004] In the process of developing this application, the following problems were found with the technology: the existing environmental protection denitrification spray device requires manual cleaning and replacement of the filter screen by the staff during use, which means that the staff have to clean and replace the filter screen multiple times in a short period of time, thereby increasing the amount of labor required for the staff to operate the device to filter the gas.

[0005] Therefore, an environmentally friendly denitrification spray device is proposed. Summary of the Invention

[0006] The purpose of this utility model is to solve the problem that existing environmental protection denitrification spray devices require manual cleaning and replacement of the filter screen by staff during use, resulting in staff having to clean and replace the filter screen multiple times in a short period of time. This utility model provides an environmental protection denitrification spray device.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] An environmentally friendly denitrification spray device includes a spray tower, a filtration mechanism, and a sealing mechanism. A slot is provided on one side of the spray tower, and the filtration mechanism is installed inside the slot. An air inlet pipe is installed at the air inlet end of the filtration mechanism. A cleaning mechanism is provided inside the filtration mechanism. A protective mechanism is provided on the upper surface of the filtration mechanism. A groove is provided on the lower surface of the filtration mechanism. A collection mechanism is installed inside the groove of the filtration mechanism. A viewing window is provided on the outer surface of the collection mechanism.

[0009] Furthermore, the filtration mechanism includes a filter frame, which is installed inside the slot of the spray tower. The upper surface of the filter frame has a groove, and a U-shaped connecting plate is slidably connected inside the slot of the filter frame. The inner wall of the U-shaped connecting plate is provided with elastic fabric, and a filter screen is installed on the inner wall of the elastic fabric. The filter screen is positioned inside the air inlet and exhaust ends of the filter frame.

[0010] The cleaning mechanism includes a motor and a connecting block. The connecting block is installed on the inner wall of the front of the filter frame. A through hole is provided on the front of the filter frame. The motor is installed on the front of the filter frame. The output shaft of the motor passes through the through hole inside the filter frame and is fitted with a rotating rod. A beater is installed on the outer surface of the rotating rod. The side of the beater away from the rotating rod abuts against the side of the filter screen away from the spray tower. The connecting block is installed on the inner wall of the front of the filter frame. A spring telescopic rod is provided on the side of the connecting block near the filter screen. The side of the spring telescopic rod near the beater abuts against the side of the filter screen away from the rotating rod.

[0011] Furthermore, the protective mechanism includes a sealing cover, a fixing block one, and a hinge. The sealing cover is hinged to the upper surface of the filter frame via the hinge. A limiting block is installed on the top of the inner wall of the sealing cover. The lower surface of the limiting block and the lower surface of the sealing cover are parallel. The U-shaped connecting plate is located on the rotation path of the limiting block. A slot is formed on the lower surface of the sealing cover. A rubber pad is provided inside the slot of the sealing cover. A fixing block two is provided on the side of the sealing cover away from the hinge. The fixing block one is installed on the upper surface of the filter frame. A slot is formed on one side of both the fixing block one and the fixing block two. A connecting rod is slidably connected inside the slot of the fixing block one. The position of the slot inside the fixing block two is located on the movement path of the connecting rod.

[0012] Furthermore, the collection mechanism includes a collection box, the lower surface of the filter frame has a groove, the collection box is snapped into the groove of the filter frame, the bottom of the inner wall of the filter frame has an arc-shaped groove, the top of the collection box is located inside the arc-shaped groove of the filter frame, and a limiting plate is provided inside the collection box.

[0013] Furthermore, the front of the collection box is provided with a positioning slot, and a viewing window is provided inside the positioning slot.

[0014] Furthermore, the sealing mechanism includes a U-shaped fixing plate, which is installed on the outer surface of the collection box. The upper surface of the U-shaped fixing plate has a slot, and a sealing gasket is provided inside the slot. The lower surfaces of the U-shaped fixing plate and the filter frame have two sets of threaded holes, and bolts are threaded into the two sets of threaded holes of the U-shaped fixing plate and the filter frame.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model uses a starting motor to drive a rotating rod and a beater to rotate, causing the beater to beat the filter screen. A spring telescopic rod, with its side near the rotating rod, abuts against one side of the filter screen. As the filter screen is beaten and moved, the spring telescopic rod is compressed, which in turn increases the oscillation frequency of the filter screen. This causes dust and debris accumulated on the surface of the filter screen to fall off during the shaking and beating process, thereby reducing the time and labor required for subsequent cleaning of the filter screen and improving the practicality of the device.

[0017] 2. This utility model, by rotating the sealing cover, brings the lower surface of the limiting block against the upper surface of the U-shaped connecting plate. Then, by pushing the connecting rod, the connecting rod is inserted into the slots of fixing block one and fixing block two. This restricts the movement of the U-shaped connecting plate within the filter frame slot, thus minimizing movement during subsequent use. When the lower surface of the limiting block abuts against the upper surface of the U-shaped connecting plate, the lower surface of the rubber pad simultaneously abuts against the upper surface of the filter frame, sealing the connection between the U-shaped connecting plate and the filter frame slot, thereby improving the sealing performance of the subsequent filtration mechanism during use.

Therefore, they should not be construed as limitations on this utility model.

[0027] As shown in Figure 1 to Figure 4As shown, an environmentally friendly denitrification spray device includes a spray tower 1, a filter mechanism 2, and a sealing mechanism 8. A slot is provided on one side of the spray tower 1, and the filter mechanism 2 is installed inside the slot. An air inlet pipe 3 is installed at the air inlet end of the filter mechanism 2. A cleaning mechanism 4 is installed inside the filter mechanism 2. A protective mechanism 7 is provided on the upper surface of the filter mechanism 2, and a groove is provided on the lower surface of the filter mechanism 2. A collection mechanism 5 is installed inside the groove of the filter mechanism 2, and a viewing window 6 is provided on the outer surface of the collection mechanism 5. Specifically, by activating the cleaning mechanism 4, the output end of the cleaning mechanism 4 is used to beat the filter equipment inside the filter mechanism 2, causing the filter equipment inside the filter mechanism 2 to swing left and right. This causes the dust and debris accumulated on the surface of the filter equipment inside the filter mechanism 2 to fall off during the shaking and beating process, thereby reducing the time and labor required for subsequent cleaning of the filter equipment inside the filter mechanism 2, thus improving the practicality of the device.

[0028] As shown in Figure 1 to Figure 3 As shown, the filter mechanism 2 includes a filter frame 201, which is installed inside the slot of the spray tower 1. The upper surface of the filter frame 201 has a groove. A U-shaped connecting plate 202 is slidably connected inside the slot of the filter frame 201. An elastic fabric 203 is provided on the inner wall of the U-shaped connecting plate 202. A filter screen 204 is installed on the inner wall of the elastic fabric 203. The filter screen 204 is positioned inside the air inlet and exhaust ends of the filter frame 201.

[0029] The cleaning mechanism 4 includes a motor 401 and a connecting block 404. The connecting block 404 is installed on the inner wall of the front of the filter frame 201. A through hole is provided on the front of the filter frame 201. The motor 401 is installed on the front of the filter frame 201. The output shaft of the motor 401 passes through the through hole inside the filter frame 201 and a rotating rod 402 is installed thereon. A beater 403 is installed on the outer surface of the rotating rod 402. The side of the beater 403 away from the rotating rod 402 abuts against the side of the filter screen 204 away from the spray tower 1. The connecting block 404 is installed on the inner wall of the front of the filter frame 201. A spring telescopic rod 405 is provided on the side of the connecting block 404 near the filter screen 204. The side of the spring telescopic rod 405 near the beater 403 abuts against the side of the filter screen 204 away from the rotating rod 402. Specifically, starting the motor 401 drives the rotating rod 402 and the beater 403. The device rotates, causing the clapper 403 to strike the filter screen 204. A spring-loaded telescopic rod 405, located near the rotating rod 402, abuts against one side of the filter screen 204. As the filter screen 204 moves under the impact, the spring-loaded telescopic rod 405 is compressed, increasing the oscillation frequency of the filter screen 204. This causes accumulated dust and debris on the surface of the filter screen 204 to fall off during the shaking and striking process, reducing the time and labor required for cleaning the filter screen 204 and thus improving the device's practicality.

[0030] As shown in Figure 1 and Figure 2 As shown, the protective mechanism 7 includes a sealing cover 701, a fixing block 703, and a hinge 707. The sealing cover 701 is hinged to the upper surface of the filter frame 201 via the hinge 707. A limit block 702 is installed on the top of the inner wall of the sealing cover 701. The lower surface of the limit block 702 is parallel to the lower surface of the sealing cover 701. The U-shaped connecting plate 202 is located on the rotation path of the limit block 702. A slot is provided on the lower surface of the sealing cover 701. A rubber pad 705 is provided inside the slot of the sealing cover 701. A fixing block 706 is provided on the side of the sealing cover 701 away from the hinge 707. The fixing block 703 is installed on the upper surface of the filter frame 201. A slot is provided on one side of both the fixing block 703 and the fixing block 706. A connecting rod 704 is slidably connected inside the slot of the fixing block 703. The slot inside the fixing block 706 is located at the position of the connecting rod 704. On the movement path;

[0031] Specifically, by rotating the sealing cover 701, the lower surface of the limiting block 702 abuts against the upper surface of the U-shaped connecting plate 202. Then, by pushing the connecting rod 704, the connecting rod 704 is inserted into the slots of the fixing block 1 703 and the fixing block 2 706. This restricts the movement of the U-shaped connecting plate 202 within the slot of the filter frame 201, thereby minimizing movement of the U-shaped connecting plate 202 during subsequent use. When the lower surface of the limiting block 702 abuts against the upper surface of the U-shaped connecting plate 202, the lower surface of the rubber pad 705 simultaneously abuts against the upper surface of the filter frame 201. This seals the connection between the U-shaped connecting plate 202 and the slot of the filter frame 201, thereby improving the sealing performance of the filter mechanism 2 during subsequent use.

[0032] As shown in Figure 1 to Figure 3 As shown, the collection mechanism 5 includes a collection box 501. A groove is formed on the lower surface of the filter frame 201, and the collection box 501 is snapped into the groove of the filter frame 201. An arc-shaped groove is formed at the bottom of the inner wall of the filter frame 201. The top of the collection box 501 is located inside the arc-shaped groove of the filter frame 201. A limiting plate 502 is provided inside the collection box 501. Specifically, by positioning the collection box 501 inside the arc-shaped groove of the filter frame 201, dust and debris discharged by the subsequent cleaning mechanism 4 slide down the inner wall of the arc-shaped groove of the filter frame 201 into the collection box 501, thereby allowing the collection box 501 to collect the debris and dust accumulated inside the filter frame 201. The limiting plate 502, positioned inside the collection box 501, divides the interior of the collection box 501 into two areas, and the limiting plate 502 directs the airflow towards the collection box 501. The movement path of gas at the bottom of the inner wall is restricted to minimize the risk of gas being blown up by the gas discharged into the filter frame 201 by the subsequent air intake pipe 3, which would cause the dust and debris discharged by the subsequent cleaning mechanism 4 to continuously block the filter screen 204.

[0033] As shown in Figure 1 and Figure 2 As shown, the front of the collection box 501 has a positioning slot, and a viewing window 6 is provided inside the positioning slot. Specifically, the viewing window 6 is made of transparent material, allowing staff to view the volume of debris accumulated inside the collection box 501, which facilitates the timely disassembly and movement of the collection box 501 to clean up the debris inside.

[0034] like Figure 2 and Figure 4 As shown, the sealing mechanism 8 includes a U-shaped fixing plate 801, which is installed on the outer surface of the collection box 501. A slot is provided on the upper surface of the U-shaped fixing plate 801, and a sealing gasket 803 is provided inside the slot. Two sets of threaded holes are provided on the lower surfaces of the U-shaped fixing plate 801 and the filter frame 201, and bolts 802 are threaded into the two sets of threaded holes of both the U-shaped fixing plate 801 and the filter frame 201. Specifically, by rotating the two sets of bolts 802, the upper surface of the sealing gasket 803 is pressed against the lower surface of the filter frame 201, thereby sealing the connection between the collection box 501 and the filter frame 201 with the U-shaped fixing plate 801 and the sealing gasket 803, thus minimizing the leakage of gas from inside the filter frame 201 along the connection between the collection box 501 and the filter frame 201.

[0035] In summary: By starting the motor 401, the rotating rod 402 and the striking plate 403 are driven to rotate, causing the striking plate 403 to strike the filter screen 204. The spring telescopic rod 405, located near the rotating rod 402, abuts against one side of the filter screen 204. As the filter screen 204 is struck and moved, the spring telescopic rod 405 is compressed, increasing the oscillation frequency of the filter screen 204. This causes accumulated dust and debris on the surface of the filter screen 204 to fall off during the shaking and striking process, reducing the time and labor required for subsequent cleaning. By rotating the sealing cover 701, the lower surface of the limiting block 702 abuts against the upper surface of the U-shaped connecting plate 202. Then, by pushing the connecting rod 704, it is inserted into the slots of the fixing block 703 and the fixing block 706, thus enabling the protective mechanism 7... The movement of the U-shaped connecting plate 202 inside the slot of the filter frame 201 is restricted to minimize the movement of the U-shaped connecting plate 202 during subsequent use.

[0036] Meanwhile, by positioning the collection box 501 inside the arc-shaped groove of the filter frame 201, the dust and debris discharged by the subsequent cleaning mechanism 4 slides down the inner wall of the arc-shaped groove of the filter frame 201 into the collection box 501, thereby allowing the collection box 501 to collect the debris and dust accumulated inside the filter frame 201. By rotating the two sets of bolts 802, the upper surface of the sealing gasket 803 is pressed against the lower surface of the filter frame 201, so that the U-shaped fixing plate 801 and the sealing gasket 803 seal the connection between the collection box 501 and the filter frame 201, thereby minimizing the leakage of gas from inside the filter frame 201 along the connection between the collection box 501 and the filter frame 201.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
