Description

Technical Field

[0001] The invention relates to the technical field of dust removal in a water plant dosing room, in particular to a dust removal device in a water plant dosing room. Background Art

[0002] A water plant is a factory that specializes in producing tap water. It removes impurities, bacteria and other harmful substances from the original water source (such as rivers, lakes or groundwater) through a series of water treatment processes to obtain clean and hygienic tap water. In the water plant's water production process, powdered agents are often used to prepare coagulants and other liquid medicines, and powdered agents are usually added to the dissolution tank manually to improve water quality or meet specific treatment requirements. Large amounts of dust will be generated when adding drugs. The dust removal device in the dosing room is a device for treating the dust generated during dosing.

[0003] However, at present, the dust generated when adding medicine in the dosing room is usually collected by installing an axial flow fan at the dosing port, and the collected drug dust is thrown into the water pool again from the end of the pipeline, and a spraying device is installed at the end of the pipeline to increase the weight of the collected drug powder to facilitate the drug input. However, when adding medicine outside the dosing port, there will be a lot of drug powder dust. If it is not collected and processed, the drug powder will float in the operation room, affecting the health of employees; and the spraying equipment at the end of the pipeline can only spray at the same position, and the spraying range is limited and not uniform.

When adding medicine to the inside of the water pool, it is added from the dosing port. At this time, the water pump is started to suck the internal water of the water pool into the inside of the water inlet pipe, and then sprayed out from the spray pipe to reduce the dust of the medicine powder inside the protective cover.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figure 1-Figure 12As shown, a dust removal device in a dosing room of a waterworks according to the present invention comprises a base plate 1, a protective cover 6 installed on the base plate 1, a dosing port 2 is provided on the base plate 1 and the protective cover 6, a dust reduction mechanism 4 is installed on the protective cover 6, a dust suction mechanism 3 is installed on the protective cover 6, a feeding mechanism 5 is installed at the end of the dust suction mechanism 3, a transmission mechanism 7 is installed between the feeding mechanism 5 and the dust suction mechanism 3, and a stirring mechanism 8 is installed inside the feeding mechanism 5; the feeding mechanism 5 comprises a mounting plate 501 and a feeding pipe 506, the side wall of the protective cover 6 is fixedly connected with the mounting plate 501, the dust suction mechanism 3 is connected with the feeding pipe 506, a motor 502 is installed on the mounting plate 501, and the output of the motor 502 The end is fixedly connected with a rotating shaft 503, the side wall of the discharge pipe 506 is fixedly connected with a fixed plate 505, the fixed plate 505 is rotatably connected with a cam 504, the cam 504 is fixedly connected to the end of the rotating shaft 503, the inside of the discharge pipe 506 is horizontally slidably connected with a sieve plate 509, the side wall of the sieve plate 509 is fixedly connected with a push rod 507 slidably connected with the discharge pipe 506, a first spring 510 is clamped between the sieve plate 509 and the discharge pipe 506, and the push rod 507 is correspondingly arranged with the cam 504; the dust reduction mechanism 4 includes a spray pipe 405 and a rotary joint 404, the inside of the protective cover 6 is provided with a spray pipe 405, and the spray pipe 405 is installed with a rotary joint 404; the transmission The driving mechanism 7 includes two pulleys 702, the rotating joint 404 and the rotating shaft 503 are fixedly connected with the pulleys 702, and a belt 701 is connected between the two pulleys 702; the unloading mechanism 5 also includes a roller 508, and the end of the push rod 507 located outside the unloading pipe 506 is rotatably connected with the roller 508, and the roller 508 and the cam 504 are in conflict; the powder processed by the cyclone separator 308 falls onto the sieve plate 509, and the motor 502 is started to realize that the rotating shaft 503 drives the cam 504 to rotate. After the cam 504 rotates, it intermittently hits the push rod 507, and the roller 508 at the end of the push rod 507 can reduce the friction force, so that the cam 504 hits more smoothly. When the push rod 507 is installed, the sieve plate 509 moves to the right, the first spring 510 contracts, and after the cam 504 is separated from the roller 508, the first spring 510 resets the screen plate 509. This reciprocating process enables the powder retained on the screen plate 509 to intermittently fall into the inside of the discharge pipe 506. The discharge pipe 506 is directly inserted into the inside of the pool without causing dust to be raised again during discharge. At the same time, the screen plate 509 is moving, which can prevent the powder at the cyclone separator 308 from falling into the water at once and causing agglomeration. When the shaft 503 rotates, the belt 701 cooperates with the pulley 702 to drive the rotary joint 404 to intermittently make a circular motion, so the spray pipe 405 located at the bottom of the rotary joint 404 will also rotate accordingly, thereby increasing the spray range and facilitating the treatment of the powder inside the protective cover 6.

[0035] Specifically, Figure 1 picture, Figure 2 , Figure 3 and Figure 4 As shown, the dust reduction mechanism 4 also includes a base frame 401, the base frame 401 is installed at the bottom of the base plate 1, a water pump 402 is installed on the base frame 401, the water pump 402 is connected to a water inlet pipe 403, the water inlet pipe 403 runs through the interior of the protective cover 6, and the end of the water inlet pipe 403 is connected to a rotary joint 404; as shown in the figure, the spray pipe 405 is located at the inner center of the protective cover 6, and the center of the spray pipe 405 and the center of the dosing port 2 are located on the same axis; the dust suction mechanism 3 also includes a shell 301, a shell 301 is provided on the side of the protective cover 6, and a wind cover 304 is installed on the shell 301, The hood 304 is detachably connected with a delivery pipe 307, the protective cover 6 is provided with a bracket 306, the bracket 306 is fixedly connected to the hood 304, the bottom end of the delivery pipe 307 is fixedly connected to the cyclone separator 308, and an axial flow fan 309 is installed inside the hood 304; the dust collecting mechanism 3 also includes an electric push rod 302, a slide groove 303 and a bellows 305, two slide grooves 303 are provided on the sides of the protective cover 6, the housing 301 is slidably connected to the slide groove 303, and the hood 304 and the delivery pipe 307 are detachably connected with the bellows 305 by screws; the water plant is in the process of water treatment When the bottom plate 1 is installed on the pool, the installation of the entire device is completed. At this time, the water pump 402 and the bottom end of the feed pipe 506 located on the bottom frame 401 are inserted into the water inside the pool. When adding medicine, pour the powder into the dosing port 2 to make the powder and water mix and react to complete the treatment. When adding medicine, start the water pump 402. At this time, the water cup water inlet pipe 403 inside the pool is transported to the rotary joint 404, and finally sprayed out from the spray pipe 405 to complete the treatment of the powder dust inside the protective cover 6; when adding medicine, the electric push rod 302 located outside the protective cover 6 is in a retracted state, and the shell 301 is located on the top of the protective cover 6, which will not affect the operator. The operator adds medicine. After the addition is completed, the operator leaves the protective cover 6, and the two electric push rods 302 extend to push the shell 301 down, the bellows 305 opens, and the shell 301 moves inside the slide 303 to avoid shaking left and right. When the shell 301 descends, the axial flow fan 309 inside the wind cover 304 starts to absorb the dust outside the protective cover 6 to prevent the dust from floating in the operation room and endangering the health of the operator. The absorbed powder reaches the inside of the cyclone separator 308 through the conveying pipe 307, and the cyclone separator 308 separates the powder in the air into the inside of the discharge pipe 506, and the clean air is discharged from the exhaust port of the cyclone separator 308.

[0036] Specifically, Figure 5 , Figure 8 , Fig.11 and Fig.12 As shown, the stirring mechanism 8 includes a pressure rod 801 and a side plate 803. The side wall of the feed tube 506 is fixedly connected to the side plate 803. The pressure rod 801 is slidably connected to the side plate 803. The bottom of the pressure rod 801 is fixedly connected to a connecting plate 802 extending to the bottom side of the feed tube 506. The top of the pressure rod 801 is fixedly connected to a chassis 804. The chassis 804 is provided with a fixed ball 807. The bottom of the cam 504 is fixedly connected to a through-fixed The top plate 805 of the fixed plate 505 has a pressure ball 808 fixedly connected to the bottom of the top plate 805, and the pressure ball 808 contacts the fixed ball 807. A second spring 806 is clamped between the bottom plate 804 and the side plate 803. The top plate 805 and the bottom plate 804 have the same diameter, and the fixed balls 807 are distributed on the surface of the bottom plate 804 in a circular array. The stirring mechanism 8 also includes a pressure seat 809, and the connecting plate 802 is fixedly connected with a pressure ball 808 located on the feeding pipe. The pressure seat 809 inside 506 is in a truncated cone structure; the cross section of the feed tube 506 is in a rectangular structure, and the bottom of the feed tube 506 is flush with the bottom of the bottom frame 401; when the cam 504 rotates, it also drives the top plate 805 to rotate. As the top plate 805 rotates, the pressure ball 808 at the bottom of the top plate 805 intermittently hits the fixed ball 807 arranged on the circumference of the bottom plate 804. When the fixed ball 807 contacts the pressure ball 808, the pressure ball 808 When the pressure rod 801 is lifted up, the second spring 806 between the bottom plate 804 and the side plate 803 will shrink. When the pressure ball 808 is separated from the fixed ball 807, the second spring 806 will be reset and the pressure rod 801 will rise. As the pressure rod 801 rises and falls, the connecting plate 802 will rise and fall accordingly. Then, the pressure seat 809 inside the discharge pipe 506 will also move up and down, stirring the water inside the discharge pipe 506, which is beneficial for the reaction of the fallen medicine powder with the water and also avoids agglomeration.

[0037] When the present invention is in use, first, when treating water, the water plant installs the bottom plate 1 on the pool to realize the installation of the entire device. At this time, the water pump 402 and the bottom end of the feed pipe 506 located on the base frame 401 are inserted into the water inside the pool. When adding medicine, pour the medicine powder into the medicine adding port 2 to make the medicine powder and water mix and react to complete the treatment. When adding medicine, the water pump 402 is started. At this time, the water cup water inlet pipe 403 inside the pool is transported to the rotary joint 404, and finally sprayed out from the spray pipe 405 to complete the treatment of the medicine powder dust inside the protective cover 6; when adding medicine, the electric push rod 302 located outside the protective cover 6 is in a retracted state, and the shell 301 is located at the top of the protective cover 6. The operator does not have any influence on the adding of medicine. After the adding of medicine, the operator leaves the protective cover 6, and the two electric push rods 302 extend to push the outer shell 301 down, the bellows 305 opens, and the outer shell 301 moves inside the slide 303 to avoid shaking left and right. When the outer shell 301 descends, the axial flow fan 309 inside the wind cover 304 starts to absorb the dust outside the protective cover 6 to prevent the dust from floating in the operation room and endangering the health of the operator. The absorbed powder passes through the conveying pipe 307 to the inside of the cyclone separator 308, and the cyclone separator 308 separates the powder in the air into the inside of the feeding pipe 506, and the clean air is discharged from the exhaust port of the cyclone separator 308;

[0038] Then, the medicine powder processed by the cyclone separator 308 falls onto the sieve plate 509, and the motor 502 is started to realize that the shaft 503 drives the cam 504 to rotate. After the cam 504 rotates, it intermittently hits the push rod 507. The roller 508 at the end of the push rod 507 can reduce the friction force, so that the cam 504 hits more smoothly. When the push rod 507 is installed, the sieve plate 509 moves to the right, and the first spring 510 contracts. After the cam 504 is separated from the roller 508, the first spring 510 resets the sieve plate 509, and the reciprocating process is realized. The powder on 9 intermittently falls into the inside of the discharge pipe 506. The discharge pipe 506 is directly inserted into the inside of the pool to prevent dust from being raised again when the material is discharged. At the same time, the sieve plate 509 is moving, which can prevent the powder at the cyclone separator 308 from falling into the water at once and causing agglomeration. When the rotating shaft 503 rotates, the belt 701 cooperates with the pulley 702 to drive the rotary joint 404 to make intermittent circular motion, and then the spray pipe 405 located at the bottom of the rotary joint 404 will also rotate accordingly, increasing the spray range, which is beneficial to the treatment of the powder inside the protective cover 6;

[0039] Finally, when the cam 504 rotates, the top plate 805 is also driven to rotate. As the top plate 805 rotates, the pressure ball 808 at the bottom of the top plate 805 intermittently hits the fixed ball 807 arranged on the circumference of the bottom plate 804. When the fixed ball 807 contacts the pressure ball 808, the pressure rod 801 will drop, and the second spring 806 located between the bottom plate 804 and the side plate 803 will shrink. When the pressure ball 808 separates from the fixed ball 807, the second spring 806 is reset and the pressure rod 801 rises. As the pressure rod 801 rises and falls, the connecting plate 802 rises and falls accordingly. Then, the pressure seat 809 located inside the discharge pipe 506 will also move up and down to stir the water inside the discharge pipe 506, which is conducive to the reaction of the fallen medicine powder with the water and also avoids agglomeration.
