Description

Technical Field

[0001] This utility model belongs to the technical field of dust purification equipment, and specifically relates to a dust purification device for aluminum powder workshops. Background Technology

[0002] In aluminum powder production workshops, a large amount of dust is generated during the processing, transportation, and storage of aluminum powder. This aluminum dust not only seriously pollutes the working environment and affects the health of workers, but long-term inhalation of aluminum dust may also lead to occupational diseases such as alumina pneumoconiosis. Moreover, aluminum dust is flammable and explosive. When the concentration of aluminum dust in the air reaches a certain range, it can easily cause an explosion when exposed to a source of ignition or high temperature, posing a huge threat to safe production in the workshop.

[0003] Referring to patent publication number CN207941330U, a dust purification device for an aluminum powder workshop is disclosed, including a base, a support, a mechanical pump, a liquid storage tank, a liquid supply tank, a medicine tank, and a spraying device. The spraying device is equipped with several nozzles. The liquid supply tank is connected to a storage tank inside the base via a delivery pipe. A lifting device is provided on the base, and a lifting plate is provided at the upper end of the lifting device. The support and the liquid storage tank are located on the lifting plate. A fan is installed inside the support, and the fan is connected to a drive motor. A controller is also provided on the lifting plate, which connects to and controls the drive motor, the mechanical pump, and the lifting device. The advantages of this utility model are that the equipment can not only remove dust from the area directly below the spraying device, but also use the fan to draw air dust from the areas on both sides to the area below the spraying device for dust removal, thus increasing the dust removal efficiency of the equipment. In addition, it can meet the dust removal needs of different working environments and makes the equipment simpler and more convenient to use.

[0004] The aforementioned patent uses a fixed spray pattern to remove aluminum powder dust, but it cannot adjust the spray intensity in a timely manner according to the size of the dust particles. When faced with large dust particles, the weaker spray intensity is insufficient to fully cover and capture them, resulting in some dust not being able to settle effectively. This leads to a high concentration of aluminum powder dust remaining in the workshop, making it difficult to meet the strict requirements for workshop air quality and safe production.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a dust purification device for aluminum powder workshops to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a dust purification device for an aluminum powder workshop, comprising a base, a water storage tank mounted on the upper end of the base, a purification tank connected to the water storage tank, a powder inlet pipe mounted on one end of the purification tank, a dust extraction mechanism mounted inside the powder inlet pipe, a particle counter mounted inside the powder inlet pipe and located on one side of the dust extraction mechanism, a water pump inlet connected to the bottom of the water storage tank, a water pipe connected to the water pump outlet, a liquid inlet box fixedly mounted on the top of the purification tank, the other end of the water pipe connected to the liquid inlet box, multiple spraying mechanisms mounted inside the liquid inlet box, a driving mechanism sleeved on the liquid inlet box, the driving mechanism engaging with the multiple spraying mechanisms, and a filter plate mounted inside the purification tank and located below the powder inlet pipe.

[0012] Furthermore, a rotating gear is fixedly installed at one end of the rotating shaft, and a sphere is fixedly installed at the other end of the rotating shaft.

[0030] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0032] Please see Figures 1-7 As shown, this utility model is a dust purification device for an aluminum powder workshop, including a base 1, a water storage tank 12 installed on the upper end of the base 1, a purification tank 2 connected to the water storage tank 12, a powder inlet pipe 3 installed at one end of the purification tank 2, a dust extraction mechanism 4 installed inside the powder inlet pipe 3, a particle counter 5 installed inside the powder inlet pipe 3 and located on one side of the dust extraction mechanism 4, a water pump 6 inlet end connected to the bottom of the water storage tank 12, a water pipe 7 connected to the outlet end of the water pump 6, a liquid inlet tank 8 fixedly installed at the top of the purification tank 2, the other end of the water pipe 7 connected to the liquid inlet tank 8, a plurality of spraying mechanisms 9 installed inside the liquid inlet tank 8, a drive mechanism 10 sleeved on the liquid inlet tank 8, the drive mechanism 10 meshing with the plurality of spraying mechanisms 9, and a filter plate 11 installed inside the purification tank 2 and below the powder inlet pipe 3.

[0033] First, the device is pushed to the area in the workshop where dust removal is needed. Then, the dust extraction mechanism 4 is activated. The dust extraction mechanism 4 generates suction force to draw the air containing aluminum powder dust into the powder inlet pipe 3, and then into the purification tank 2. The particle counter 5 located in the powder inlet pipe 3 detects the number of aluminum powder dust particles in the air and the size of each particle (the particle counter 5 is existing technology and will not be described in detail here). The particle counter 5 transmits the detection data to the controller (the controller is existing technology and is not shown in the figure). At the same time, the controller controls the water pump 6 to start working, drawing water from the water storage tank 12 and transporting it through the water pipe 7 to the top of the purification tank 2. The mixture of water and chemicals is first placed in the inlet tank 8 of the main unit, and then enters each spraying mechanism 9. When the particle counter 5 detects a high proportion of fine dust, it transmits the detection data to the controller. The controller then controls the drive mechanism 10 to start, which drives multiple spraying mechanisms 9 to rotate synchronously on the inlet tank 8. This causes the water and chemicals mixture sprayed from the spraying mechanism 9 to form a fine mist, increasing the contact probability between the droplet surface area and the dust to capture suspended fine particles. During this process, the controller controls the water pump 6 to simultaneously pressurize and transport the water and chemicals from the water storage tank 12 to the inlet tank 8. After being atomized by the spraying mechanism 9, the mixture is then discharged into the purification tank 2. A multi-layered, three-dimensional spray field is formed, where water mist and dust particles come into full contact. Through inertial collision and agglomeration, the dust particles become heavier and settle. When the particle counter 5 detects a high proportion of aluminum dust, the controller will also control the drive mechanism 10. The drive mechanism 10 will then adjust the spraying mechanism 9 to form a high-intensity water curtain spray of water and agent mixture. The larger droplets are used to envelop large aluminum dust particles by inertia, thus enhancing the settling effect. This allows for the timely capture and settling of larger aluminum dust particles, ensuring the purification effect. The particle counter 5 detects the proportion of aluminum dust particles entering the purification tank 2, causing the drive mechanism 10 to adjust simultaneously. Multiple spraying mechanisms 9 spray water and chemical mixtures in the form of water mist or water curtain to suppress aluminum powder dust particles, enabling the entire purification device to achieve intelligent and dynamic dust suppression. This avoids the drawback of traditional devices that cannot flexibly adjust when the amount of dust changes. After dust suppression, the aluminum powder dust particles, along with the water and chemical mixture, fall onto the filter plate 11. The water and chemical mixture will pass through the filter plate 11 and re-enter the water storage tank 12. The water and chemical mixture in the water storage tank 12 will participate in the next dust suppression operation, thus recycling the water and chemicals. The aluminum powder dust particles after dust suppression will remain above the filter plate 11.

[0034] In one embodiment, the dust extraction mechanism 4 includes a support frame 401, which is fixedly installed on the inner wall of the powder inlet pipe 3, and a drive motor 402 is fixedly installed on the support frame 401.

[0035] An output shaft 403 is fixedly installed at the output end of the drive motor 402, and a fixing block 404 is fixedly installed at the other end of the output shaft 403. Multiple fan blades 405 are fixedly installed on the outer wall of the fixing block 404.

[0036] The drive motor 402, which is fixedly installed on the support frame 401, is started. The output shaft of the drive motor 402 drives the output shaft 403, which is fixedly installed on it, to rotate. Then, the output shaft 403 drives the fixed block 404 to rotate. Subsequently, the fixed block 404 drives the multiple fan blades 405, which are fixedly installed on its outer wall, to rotate. The rotation of the multiple fan blades 405 generates suction force in the cavity of the powder inlet pipe 3, drawing the air containing aluminum powder dust into the powder inlet pipe 3. Then, the air enters the purification tank 2 through the powder inlet pipe 3 to complete the next dust reduction operation.

[0037] In one embodiment, the spraying mechanism 9 includes a rotating shaft 901 and a plurality of balls 902, which are connected by a connecting shaft 903. The rotating shaft 901 is rotatably mounted on the liquid inlet tank 8.

[0038] A rotating gear 904 is fixedly installed at one end of the rotating shaft 901, and a sphere 902 is fixedly installed at the other end of the rotating shaft 901.

[0039] The sphere 902 is symmetrically provided with a plurality of water mist holes 905 and a water curtain hole 906. The liquid inlet tank 8 is provided with a plurality of round holes 801, and the plurality of spheres 902 are respectively located in the plurality of round holes 801.

[0040] The drive mechanism 10 includes two hydraulic rods 1001, which are symmetrically mounted on the top of the purification tank 2.

[0041] A movable ring 1003 is installed on the telescopic ends of the two hydraulic rods 1001. A plurality of gear racks 1004 are fixedly installed on the bottom of the movable ring 1003, and the plurality of gear racks 1004 mesh with the plurality of rotating gears 904 respectively.

[0042] When particle counter 5 detects a high proportion of fine dust, it transmits the detection data to the controller. The controller then simultaneously controls the operation of two hydraulic rods 1001. The extension and retraction ends of each hydraulic rod 1001 simultaneously move the fixedly mounted moving ring 1003. The moving ring 1003 then moves the multiple gear racks 1004 fixedly mounted at their lower ends. The rotating gears 904 meshing with these gear racks 1004 rotate as they move, and each rotating gear 904 drives its fixedly mounted rotating shaft 901 in the liquid inlet tank. As the spheres 902 rotate, connected by a connecting shaft 903, and with the other end of the rotating shaft 901 fixedly mounted to another sphere 902, the rotation of the rotating shaft 901 will cause the remaining spheres 902 and the connecting shafts 903 to rotate together. This allows the spheres 902 to switch positions, ensuring that the multiple water mist holes 905 on each sphere 902 face the inner cavity of the purification tank 2 through the round holes 801. At this time, the mixture of water and chemicals from the inlet tank 8 will enter the sphere 902 through the multiple water mist holes 905 and two water curtain holes 906 on the other side, and then flow from the hole facing the purification tank 2. Multiple water mist nozzles 905 spray out a fine mist of water and chemicals, increasing the contact probability between the droplet surface area and the dust to capture suspended fine particles. During this process, the controller simultaneously controls the water pump 6 to pressurize and transport the water and chemicals from the water storage tank 12 to the inlet tank 8. Then, multiple spheres 902 atomize the chemicals through their multiple water mist nozzles 905, forming a multi-layered three-dimensional spray field within the purification tank 2. The water mist in the spray field fully contacts the dust, causing the dust particles to increase in weight and settle through inertial collision and agglomeration. When the particle counter 5 detects a high proportion of aluminum powder dust, the controller will simultaneously control two... The hydraulic rod 1001 then performs a switching operation on each sphere 902, that is, one water curtain hole 906 on the sphere 902 faces the inner cavity of the purification tank 2 through the round hole 801. At this time, the water and chemical mixture in the liquid inlet tank 8 enters the sphere 902 through multiple water mist holes 905 on both sides and the water curtain hole 906 on the other side, and then sprays out from the water curtain hole 906 facing the purification tank 2, so that the sprayed water and chemical mixture forms a high-intensity water curtain spray. The inertia of the larger droplets wraps around the large aluminum powder dust to enhance the settling effect, thereby timely capturing and settling the larger aluminum powder dust particles and ensuring the purification effect.

[0043] The base 1 is equipped with casters 101 at each of the four corners of its bottom, and a push handle 102 is installed at one end of the top of the base 1.

[0044] When the device needs to be moved, the staff pushes the handle 102 by hand. The base 1 installed on the handle 102 can then be moved by the four casters 101, so that the device can be pushed to the area of ​​the workshop that needs aluminum powder dust purification and dust reduction.
