Description
Technical Field
[0001] The utility model relates to the technical field of industrial dust removal, in particular to a powder uniform distribution generator and a dust removal device. Background Art
[0002] At present, laser, cutting, and grinding equipment will generate a lot of dust when processing metal or non-metal materials. Industrial dust collectors are needed to collect the generated dust through pipes and put it into the dust collector for centralized treatment. When the industrial dust collector is running, a large amount of dust is distributed in the pipe. When the dust concentration is too high, if it encounters static electricity, a dust explosion will occur, causing certain harm and impact to the personnel and environment in the working area. Adding talcum powder to the pipe to suppress the explosion of functional powder is an important measure to solve this problem. However, in the actual adding process, the talcum powder is often not fully mixed with the dust, which greatly reduces the effect of talcum powder in suppressing dust explosion, and talcum powder will also cause certain impact on the human body. Utility Model Content
[0003] The utility model aims to provide a powder uniform distribution generator and a dust removal device, so as to provide a technical solution that can uniformly provide functional powder to the dust removal device, thereby allowing the functional powder to be fully mixed with dust.
[0004] Based on this, the utility model provides a powder uniform distribution generator, which is used in a dust removal device. The uniform distribution generator includes: a functional powder generator cavity, a functional powder exhaust flow channel arranged on the functional powder generator cavity, a first throttling device arranged on the functional powder generator cavity, an intake flow channel arranged in the functional powder generator cavity, and an air hole structure arranged on the intake flow channel.
[0005] The functional powder exhaust flow channel is connected with the pipeline of the dust removal device, the first throttling member is connected with the intake flow channel, and is used to pass compressed air into the intake flow channel, the pore structure is used to blow the compressed air toward the inner wall of the functional powder generator cavity, so as to blow the functional powder attached to the inner wall of the functional powder generator cavity into the functional powder generator cavity, the second throttling member is connected with the functional powder generator cavity, and is used to pass compressed air into the functional powder generator cavity, so as to ensure that the functional powder in the functional powder generator cavity is in a suspended state, and under the coordinated action of the first throttling member and the second throttling member, the functional powder can evenly enter the pipeline of the dust removal device through the functional powder exhaust flow channel.
[0006] When adopting the above-mentioned technical scheme, the utility model utilizes the first throttle member and the intake air duct to pass compressed air into the functional powder generator cavity, and utilizes the pore structure to blow the compressed air toward the inner wall of the functional powder generator cavity, so as to blow the functional powder attached to the inner wall of the functional powder generator cavity into the functional powder generator cavity. The utility model can also provide a stable direct current air path for the functional powder generator cavity by adjusting the intake flow rate of the second throttle valve, so as to ensure that the functional powder inside the functional powder generator cavity is always in a suspended state, based on this, and then enters the pipeline of the dust removal device through the functional powder exhaust flow duct, and then evenly enters the dust removal device through the pipeline to be fully mixed with the dust in the dust removal device. In practice, when the functional powder is talcum powder, the utility model can solve the technical problem that the effect of talcum powder in suppressing dust explosion is greatly reduced due to the inability of talcum powder to be fully mixed with dust. At the same time, it avoids the precipitation and waste of talcum powder, saves the cost of using talcum powder, and avoids the damage to the human body caused by the large-scale use of talcum powder or the artificial addition of talcum powder.
[0007] In a possible implementation, the inlet flow channel is disposed close to an inner wall of the functional powder generator cavity.
[0008] When the above-mentioned technical solution is adopted, since the intake air duct in the utility model is arranged close to the inner wall of the functional powder generator cavity, the compressed air flowing out through the intake air duct can act on the inner wall of the functional powder generator cavity with greater force, so as to blow more functional powder attached to the inner wall of the functional powder generator cavity into the functional powder generator cavity.
[0009] In a possible implementation, the intake air passage has a gradient spiral structure.
[0010] When adopting the above-mentioned technical solution, the air inlet channel can be spirally arranged near the inner wall of the functional powder generator cavity, so that the inner wall of the functional powder generator cavity can be basically completely covered by the compressed air in the air inlet channel, so as to basically completely blow the functional powder attached to the inner wall of the functional powder generator cavity into the functional powder generator cavity.
[0011] In a possible implementation, the pore structure includes a plurality of pores, and the plurality of pores are evenly arranged on the intake air passage.
[0012] When adopting the above technical solution, the inlet air duct can provide uniform compressed air to the inner wall of the functional powder generator cavity through the pore structure, so as to evenly blow the functional powder attached to the inner wall of the functional powder generator cavity into the functional powder generator cavity.
[0013] In a possible implementation, the plurality of air holes are arranged at a preset angle with the inner wall of the functional powder generator cavity, so that the gas blown out of the plurality of air holes can act obliquely on the inner wall of the functional powder generator cavity.
[0014] When adopting the above-mentioned technical solution, it should be understood that when the compressed gas acts on the inner wall of the functional powder generator cavity at an angle, the functional powder attached to the inner wall of the functional powder generator cavity is more easily blown away. Therefore, the setting angles of the multiple air holes in the utility model can more easily blow away the functional powder attached to the inner wall of the functional powder generator cavity.
[0015] In a possible implementation, the preset angle ranges from 30° to 60°.
[0016] In a possible implementation manner, the first throttle member and the second throttle member are arranged on a side opposite to the exhaust flow passage.
[0017] When the above-mentioned technical solution is adopted, the functional powder can be blown into the functional powder generator cavity by the compressed air introduced by the first throttle piece on the side opposite to the exhaust flow channel, and then the compressed air introduced by the second throttle piece can be used to ensure that the functional powder is suspended in the functional powder generator cavity. At this time, the uniformity of the functional powder in the pipeline of the dust removal device can be further improved.
[0018] In a possible implementation, the powder uniform distribution generator further includes an end cover, which is detachably disposed on the functional powder generator cavity and is used to add functional powder into the functional powder generator cavity.
[0019] In a possible implementation, the powder uniform distribution generator further includes an observation window disposed on the functional powder generator cavity, and the observation window is used to observe the distribution of the functional powder in the functional powder generator cavity.

The powder uniform distribution generator is connected to the dust removal device body through the pipeline and is used to introduce the functional powder into the dust removal device body.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0031] At present, laser, cutting, and grinding equipment will generate a lot of dust when processing metal or non-metal materials. Industrial dust collectors are needed to collect the generated dust through pipes and put it into the dust collector for centralized treatment. When the industrial dust collector is running, a large amount of dust is distributed in the pipe. When the dust concentration is too high, if it encounters static electricity, a dust explosion will occur, causing certain harm and impact to the personnel and environment in the working area. Adding talcum powder to the pipe to suppress the explosion of functional powder is an important measure to solve this problem. However, in the actual adding process, the talcum powder is often not fully mixed with the dust, which greatly reduces the effect of talcum powder in suppressing dust explosion, and talcum powder will also cause certain impact on the human body.
[0032] Based on this, an embodiment of the utility model provides a powder uniform distribution generator, which is used in a dust removal device. The uniform distribution generator includes: a functional powder generator cavity 7, a functional powder exhaust flow channel 9 arranged on the functional powder generator cavity 7, a first throttling member 2 and a second throttling member 1 arranged on the functional powder generator cavity 7, an intake flow channel 4 arranged in the functional powder generator cavity 7, and a pore structure 5 arranged on the intake flow channel 4. The functional powder exhaust flow channel 9 is connected to the pipeline of the dust removal device, the first throttle member 2 is connected to the intake flow channel, and is used to pass compressed air into the intake flow channel 4, the pore structure 5 is used to blow the compressed air to the inner wall of the functional powder generator cavity 7, so as to blow the functional powder attached to the inner wall of the functional powder generator cavity 7 into the functional powder generator cavity 7, the second throttle member 1 is connected to the functional powder generator cavity 7, and is used to pass compressed air into the functional powder generator cavity 7, so as to ensure that the functional powder in the functional powder generator cavity 7 is in a suspended state, and under the synergistic effect of the first throttle member 2 and the second throttle member 1, the functional powder can enter the pipeline of the dust removal device through the functional powder exhaust flow channel. Wherein, the first throttle member and the second throttle member can be throttle valves.
[0033] In practical applications, the functional powder may be talcum powder, or may be other functional powders required in practice, and the embodiments of the present invention do not specifically limit this.
[0034] When the functional powder is talcum powder, the embodiment of the utility model uses the first throttle and the intake air channel to pass the compressed air into the functional powder generator cavity, and uses the pore structure to blow the compressed air toward the inner wall of the functional powder generator cavity, so as to blow the talcum powder attached to the inner wall of the functional powder generator cavity into the functional powder generator cavity. The utility model can also provide a stable direct current air path for the functional powder generator cavity by adjusting the intake flow rate of the second throttle valve, so as to ensure that the functional powder inside the functional powder generator cavity is always in a suspended state, based on which, the functional powder enters the pipeline of the dust removal device through the functional powder exhaust flow channel, and then enters the dust removal device evenly through the pipeline to fully mix with the dust in the dust removal device. The embodiment of the utility model can solve the technical solution that the effect of talcum powder in suppressing dust explosion is greatly reduced due to the inability of talcum powder to be fully mixed with dust, and at the same time avoids the precipitation and waste of talcum powder, saves the cost of using talcum powder, and also avoids the damage to the human body caused by the large-scale use of talcum powder or the artificial addition of talcum powder.
[0035] In an actual setting, in order to allow more functional powder attached to the inner wall of the functional powder generator cavity to be blown into the functional powder generator cavity, the inlet air duct can be arranged close to the inner wall of the functional powder generator cavity so that the compressed air flowing out through the inlet air duct can act on the inner wall of the functional powder generator cavity with greater force.
[0036] In some examples, the intake air duct 4 has a gradient spiral structure, based on which the intake air duct 4 can be spirally arranged near the inner wall of the functional powder generator cavity 7, so that the compressed air in the intake air duct 4 can basically completely cover the inner wall of the functional powder generator cavity 7, so as to basically completely blow the functional powder attached to the inner wall of the functional powder generator cavity 7 into the functional powder generator cavity 7, so that the functional powder completely floats in the functional powder generator cavity 7, and then evenly enters the dust removal device through the pipeline, and is fully mixed with the dust in the dust removal device, thereby improving the dust removal efficiency.
[0037] Furthermore, the pore structure 5 includes a plurality of pores, and the plurality of pores are evenly arranged on the inlet flow channel. Based on this, the inlet flow channel 4 can provide uniform compressed air to the inner wall of the functional powder generator cavity 7 through the pore structure 5, so as to evenly blow the functional powder attached to the inner wall of the functional powder generator cavity 7 to the functional powder generator cavity 7.
[0038] It should be understood that in practice, when the compressed gas acts obliquely on the inner wall of the functional powder generator cavity, the functional powder attached to the inner wall of the functional powder generator cavity is more easily blown away. Based on this, in the embodiment of the utility model, the multiple air holes are arranged at a preset angle with the inner wall of the functional powder generator cavity, so that the gas blown out of the multiple air holes can act obliquely on the inner wall of the functional powder generator cavity. Therefore, the multiple air holes of the utility model can more easily blow away the functional powder attached to the inner wall of the functional powder generator cavity.
[0039] In practice, the preset angle ranges from 30° to 60°. It should be understood that when the preset angle is 30° to 60°, the angle between the multiple air holes and the inner wall of the functional powder generator cavity is an inclined angle, so the gas blown from the multiple air holes can act on the inner wall of the functional powder generator cavity at an inclined angle.
[0040] Exemplarily, the preset angle is 30°, or 45°, or 60°.
[0041] In an embodiment of the utility model, the first throttle member and the second throttle member are arranged on a side opposite to the exhaust flow passage.
[0042] Based on this, the functional powder can be blown into the functional powder generator cavity by the compressed air introduced through the first throttle piece on the side opposite to the exhaust flow channel, and then the compressed air introduced through the second throttle piece can be used to ensure that the functional powder is suspended in the functional powder generator cavity. At this time, the uniformity of the functional powder in the pipeline of the dust removal device can be further improved.
[0043] In a possible implementation, the powder uniform distribution generator further includes an end cover 8 , which is detachably disposed on the functional powder generator cavity 7 and is used to add functional powder into the functional powder generator cavity 7 .
[0044] In practice, when the powder distribution generator needs to add functional powder, the end cover of the powder distribution generator is opened, and after adding the required mass of powder to the powder distribution generator, the end cover is closed to complete the process of adding functional powder to the powder distribution generator.
[0045] Furthermore, the powder uniform distribution generator further comprises an observation window 6 disposed on the functional powder generator cavity, and the observation window 6 is used to observe the distribution of the functional powder in the functional powder generator cavity 7. Specifically, when a large amount of functional powder is observed to be attached to the inner wall of the functional powder generator cavity through the observation window 6, the pressure in the functional powder generator cavity can be adjusted through the second throttle member 1 to adjust the compressed air entering the intake airway through the first throttle member 2, so that the functional powder attached to the inner wall of the functional powder generator cavity 7 can be blown into the functional powder generator cavity 7.
[0046] In a specific embodiment, the functional powder is talcum powder. The working process of the powder uniform distribution generator provided by the embodiment of the utility model is: the talcum powder raw material is added into the functional powder generator cavity 7 from the detachable end cover 8 on the top of the generator, and the compressed air is passed into the first throttle valve and the second throttle valve. By adjusting the size of the first throttle valve, the compressed air intake inside the functional powder generator cavity 7 is controlled, and the compressed air enters from the main air duct 3 connected to the second throttle valve, and the talcum powder is blown and floated inside the functional powder generator cavity 7, so that the talcum powder is in a suspended state. After running for a period of time, it was found that the talcum powder was distributed in a small amount in the middle of the functional powder generator cavity 7, forming a cavity, while the amount attached to the inner wall of the functional powder generator cavity 7 was large. At this time, by adjusting the size of the first throttle valve, the compressed air was passed through the gradient spiral inlet flow channel 4, and a plurality of pore structures 5 inclined at a 45° angle to the center of the cavity were evenly distributed on the inlet flow channel 4. The talcum powder attached to the inner wall of the functional powder generator cavity 7 was fully and evenly blown away, and floated inside the entire functional powder generator cavity 7, so that the talcum powder can always be sucked into the dust collector pipe under the negative pressure of the dust collector, and be fully and evenly mixed with the dust in the pipe, thereby improving the dust removal efficiency and preventing the risk of dust explosion in the dust collector pipe caused by static sparks, thereby achieving the purpose of explosion suppression.
[0047] Based on the above description, the embodiment of the utility model solves the problem that when talcum powder is simply blown by compressed air, after running for a period of time, the talcum powder is distributed in a small amount in the middle of the cavity, forming a cavity, while a large amount of talcum powder is attached to the inner wall of the cavity. The talcum powder floats evenly in the entire cavity, and is evenly distributed in the pipeline after negative pressure self-priming of the dust collector pipeline, and is fully mixed with the dust, thereby maximizing its role in suppressing dust explosions. At the same time, the embodiment of the utility model can evenly introduce talcum powder into the dust collector, and the introduction amount can be adjusted, thereby avoiding the precipitation and waste of talcum powder, saving the cost of using talcum powder, and avoiding the damage to the human body caused by the large-scale use of talcum powder or the artificial addition of talcum powder.
[0048] Second, refer to Figure 2The embodiment of the utility model also provides a dust removal device, including the powder uniform distribution generator, the dust removal device body 11 and the dust removal device pipeline 10, the powder uniform distribution generator is connected to the dust removal device body 11 through the dust removal device pipeline 10, and is used to introduce the functional powder into the dust removal device body 11.
[0049] Specifically, when the functional powder in the powder distribution generator is talcum powder, the powder distribution generator can fully and evenly blow away the talcum powder attached to the inner wall of the cavity, and float it inside the entire cavity, so that the talcum powder can always be sucked into the pipeline of the dust removal device under the negative pressure of the dust removal device, and be fully and evenly mixed with the dust in the pipeline, thereby improving the dust removal efficiency and preventing the risk of dust explosion in the pipeline of the dust removal device due to static sparks, thereby achieving the purpose of explosion suppression.
[0050] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.
[0051] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
