Description

Technical Field

[0001] This utility model relates to a dust removal device for a sodium hyaluronate packaging workshop, belonging to the field of sodium hyaluronate production technology. Background Technology

[0002] Sodium hyaluronate powder is a common moisturizer, also known as sodium hyaluronate powder. Hyaluronic acid is a naturally occurring polysaccharide in the human body with excellent moisturizing properties, helping the skin retain moisture and increasing skin elasticity and radiance.

[0003] For example, utility model patent number 201621241776.3 discloses a sodium hyaluronate powder filling machine. It includes a base plate, a column on one side of the base plate, a connecting frame at the upper end of the column, and a funnel fixed on the connecting frame; a fixed discharge pipe at the lower end of the funnel, a movable discharge pipe sleeved outside the lower end of the fixed discharge pipe, the movable discharge pipe sliding relative to the fixed discharge pipe, a main control valve at the upper end of the fixed discharge pipe, and a handle on the movable discharge pipe; an electronic scale is installed on the base plate directly below the funnel.

[0004] While the aforementioned patent can achieve the function of bagging sodium hyaluronate powder, the current technology is not comprehensive and has the following drawbacks: Sodium hyaluronate powder is prone to dust overflow during the bagging process; the particle size of sodium hyaluronate powder is very small, and the scattered dust can easily pollute the cleanroom environment, increasing the risk of cross-contamination and potentially causing respiratory irritation to operators; conventional dust collection hoods lack a lifting auxiliary side suction mechanism, making it impossible to enhance dust collection at the bag opening where more dust is generated, resulting in poor dust removal efficiency.

[0005] To solve one of the above problems, there is an urgent need for a dust removal device for sodium hyaluronate packaging workshops. Utility Model Content

[0006] Based on the shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to achieve more precise targeting of the dust-generating position by adding a lifting auxiliary side suction mechanism, thereby improving dust removal efficiency and reducing the cost of dust removal equipment. To this end, a dust removal device for sodium hyaluronate packaging workshop is provided.

[0007] The dust removal device for the sodium hyaluronate packaging workshop of this utility model includes a main dust collection hood, characterized in that: a connecting pipe is installed on the dust outlet at the top of the main dust collection hood; a dust collection hood fixing frame fixedly connected to the connecting pipe is provided on one side of the main dust collection hood; a three-way connector communicating with the connecting pipe is provided at the top of the connecting pipe; a pneumatic gate valve is installed on the bypass interface of the three-way connector; the pneumatic gate valve is connected to a lifting auxiliary side suction mechanism; a canvas telescopic hose A is installed on the third interface of the three-way connector; the upper end of the canvas telescopic hose A is connected to the exhaust main pipe; one end of the exhaust main pipe is sealed, and the other end is connected to a dust removal and filtration module.

[0008] The main dust collection hood is located above the sodium hyaluronate packaging machine. After the dust removal and filtration module is turned on, a negative pressure is formed at the main dust collection hood. The dust-laden gas generated during the sodium hyaluronate packaging process enters the connecting pipe through the main dust collection hood, and then passes through the tee connector, canvas telescopic hose A, and exhaust pipe in sequence before entering the dust removal and filtration module for treatment. This can effectively reduce dust pollution in the sodium hyaluronate packaging workshop, effectively protect the environment and the health of the staff, and the dust removal system has a simple structure, which reduces production costs.

[0009] In addition, this application adds a lifting auxiliary side suction mechanism. After the pneumatic gate valve is opened, the lifting auxiliary side suction mechanism shares the same set of dust removal and filtration modules. The dust suction port of the lifting auxiliary side suction mechanism can be closer to the feeding position of the sodium hyaluronate packaging machine, and more accurately align with the bag opening position where more dust is generated, thereby achieving the purpose of improving dust removal efficiency and reducing the cost of dust removal equipment.

[0010] Preferably, the lifting auxiliary side suction mechanism includes an upper curved pipe and a vertical support rod. One end of the upper curved pipe is connected to a pneumatic gate valve, and the other end of the upper curved pipe passes through the top plate of the main dust collection hood and is connected to a canvas telescopic hose B. The bottom end of the canvas telescopic hose B is connected to a lower curved pipe, and a fixing plate is provided on the outer wall of the lower curved pipe. The bottom end of the vertical support rod is connected to the fixing plate through a horizontal support rod. The upper end of the vertical support rod passes through the top plate of the main dust collection hood, and an upper locking nut and a lower locking nut are threadedly connected to the external thread section at the upper end of the vertical support rod. The upper locking nut and the lower locking nut are located on the upper and lower sides of the top plate of the main dust collection hood, respectively, and the upper locking nut and the lower locking nut fix the vertical support rod to the top plate of the main dust collection hood.

[0011] Preferably, the main dust collection hood includes a top plate, which has a rectangular structure, and soft curtains are installed on all four sides of the top plate.

[0012] Preferably, the vertical support rod and the lower locking nut are integrally formed and are made of bent steel pipe.

[0013] Preferably, a connecting flange is provided on the outer wall of the upper bend pipe, and the connecting flange is fixedly connected to the top plate of the main dust collection hood by fixing bolts. This ensures the installation strength of the lifting auxiliary side suction mechanism.

[0015] Preferably, the inclined support A includes a first screw hinged to a first connecting rod and a second screw hinged to the wall. The other ends of both the first and second screws are connected to a threaded tube. The threads of the first and second screws have opposite directions, and the threaded tube has a handle. The operation steps of inclined support A and inclined support B are the same and need to be operated simultaneously. By rotating the handle, the operator changes the depth of the first and second screws inserted into the threaded tube, thus changing the length of the two sets of inclined supports, and thereby adjusting the angle between the first connecting rod, the first hinge seat, and the wall, achieving the purpose of adjusting the height of the main dust collection hood.

[0016] Preferably, the dust removal and filtration module includes a cyclone separator, a bag filter, and an induced draft fan.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The dust removal device for the sodium hyaluronate packaging workshop described in this utility model has a main dust collection hood positioned above the sodium hyaluronate packaging machine. After the dust removal and filtration module is activated, a negative pressure state is formed at the main dust collection hood. The dust-laden gas generated during the sodium hyaluronate packaging process enters the connecting pipe through the main dust collection hood, and then sequentially passes through the tee connector, canvas telescopic hose A, and exhaust main pipe before entering the dust removal and filtration module for treatment. This effectively reduces dust pollution in the sodium hyaluronate packaging workshop, effectively protecting the environment and the health of workers. Furthermore, this dust removal system has a simple structure, reducing production costs.

[0019] The dust removal device for the sodium hyaluronate packaging workshop described in this utility model, by adding a lifting auxiliary side suction mechanism, after opening the pneumatic gate valve, the lifting auxiliary side suction mechanism shares the same set of dust removal and filtration modules.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings: The present invention will be further described below through specific embodiments, but it is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0027] Example 1, such as Figure 1-2 As shown, the dust removal device for a sodium hyaluronate packaging workshop includes a main dust collection hood 1. A connecting pipe 3 is installed on the dust outlet at the top of the main dust collection hood 1. A dust collection hood fixing frame 6, which is fixedly connected to the connecting pipe 3, is provided on one side of the main dust collection hood 1. A three-way connector 4, which is connected to the connecting pipe 3, is located at the top of the connecting pipe 3. A pneumatic gate valve 5 is installed on the bypass interface of the three-way connector 4. The pneumatic gate valve 5 is connected to a lifting auxiliary side suction mechanism 2. A canvas telescopic hose A7 is installed on the third interface of the three-way connector 4. The upper end of the canvas telescopic hose A7 is connected to the exhaust main pipe 8. One end of the exhaust main pipe 8 is sealed, and the other end is connected to a dust removal and filtration module.

[0028] The main dust collection hood 1 is located above the sodium hyaluronate packaging machine. After the dust removal and filtration module is turned on, a negative pressure is formed at the main dust collection hood 1. The dust-laden gas generated during the sodium hyaluronate packaging process enters the connecting pipe 3 through the main dust collection hood 1, and then passes through the three-way connector 4, the canvas telescopic hose A7, and the exhaust pipe 8 in sequence before entering the dust removal and filtration module for treatment. This can effectively reduce dust pollution in the sodium hyaluronate packaging workshop, effectively protect the environment and the health of the staff, and the dust removal system has a simple structure, which reduces production costs.

[0029] In addition, this application adds a lifting auxiliary side suction mechanism 2. After the pneumatic gate valve 5 is opened, the lifting auxiliary side suction mechanism 2 shares the same set of dust removal and filtration modules. The dust suction port of the lifting auxiliary side suction mechanism 2 can be closer to the feeding position of the sodium hyaluronate packaging machine, and more accurately align with the position with more dust, thereby achieving the purpose of improving dust removal efficiency and reducing the cost of dust removal equipment.

[0030] Canvas telescopic hoses achieve free expansion and contraction through a spiral steel wire or folded canvas structure, with a bending radius approaching the outer diameter, facilitating installation and storage.

[0031] Example 1, such as Figure 1-2As shown, the dust removal device for a sodium hyaluronate packaging workshop includes a main dust collection hood 1. A connecting pipe 3 is installed on the dust outlet at the top of the main dust collection hood 1. A dust collection hood fixing frame 6, which is fixedly connected to the connecting pipe 3, is provided on one side of the main dust collection hood 1. A three-way connector 4, which is connected to the connecting pipe 3, is located at the top of the connecting pipe 3. A pneumatic gate valve 5 is installed on the bypass interface of the three-way connector 4. The pneumatic gate valve 5 is connected to a lifting auxiliary side suction mechanism 2. A canvas telescopic hose A7 is installed on the third interface of the three-way connector 4. The upper end of the canvas telescopic hose A7 is connected to the exhaust main pipe 8. One end of the exhaust main pipe 8 is sealed, and the other end is connected to a dust removal and filtration module.

[0032] Furthermore, referring to Figure 3 The lifting auxiliary side suction mechanism 2 includes an upper curved pipe 2.1 and a vertical support rod 2.6. One end of the upper curved pipe 2.1 is connected to a pneumatic gate valve 5, and the other end of the upper curved pipe 2.1 passes through the top plate of the main dust collection hood 1 and is connected to a canvas telescopic hose B2.3. The bottom end of the canvas telescopic hose B2.3 is connected to a lower curved pipe 2.4, and a fixing plate 2.5 is provided on the outer wall of the lower curved pipe 2.4. The bottom end of the vertical support rod 2.6 is connected to a horizontal support rod. 2.7 Connected to the fixed plate 2.5, the upper end of the vertical support rod 2.6 penetrates the top plate of the main dust collection hood 1, and the upper threaded section of the upper end of the vertical support rod 2.6 is threaded with an upper locking nut 2.8 and a lower locking nut 2.9. The upper locking nut 2.8 and the lower locking nut 2.9 are respectively located on the upper and lower sides of the top plate of the main dust collection hood 1, and the upper locking nut 2.8 and the lower locking nut 2.9 fix the vertical support rod 2.6 to the top plate of the main dust collection hood 1.

[0033] After the pneumatic gate valve 5 is opened, the lifting auxiliary side suction mechanism 2 shares the same set of dust removal and filtration modules, and negative pressure is generated at the air inlet of the lower bend pipe 2.4, so that the dust suction port of the lifting auxiliary side suction mechanism 2 can be closer to the unloading position of the sodium hyaluronate packaging machine.

[0034] Furthermore, when it is necessary to raise the height of the suction port of the lower bend 2.4, the lower locking nut 2.9 needs to be rotated by external force to adjust the lower locking nut 2.9 to be closer to the top plate of the main dust collection hood 1. Then, the height of the vertical support rod 2.6 is raised. The vertical support rod 2.6 carries the lower bend 2.4 through the horizontal support rod 2.7 and the fixing plate 2.5. Then, the upper locking nut 2.8 is adjusted to move closer to the main dust collection hood 1, and the vertical support rod 2.6 is relocked on the main dust collection hood 1. The canvas telescopic hose B2.3 is compressed, and the height of the lower bend 2.4 is adjusted.

[0035] When it is necessary to lower the height of the suction port of the lower bend 2.4, the upper locking nut 2.8 needs to be rotated by external force first. Due to its own weight, the vertical support rod 2.6 will descend by itself. After the lower bend 2.4 has descended to the correct position, the lower locking nut 2.9 is then adjusted to move closer to the main dust collection hood 1, and the vertical support rod 2.6 is relocked on the main dust collection hood 1. The canvas telescopic hose B2.3 is then stretched, thus completing the height adjustment of the lower bend 2.4.

[0036] Furthermore, the main dust collection hood 1 includes a top plate, which has a rectangular structure, and soft curtains 9 are installed on all four sides of the top plate.

[0037] Furthermore, the vertical support rod 2.6 and the lower locking nut 2.9 are integrally formed and are made of bent steel pipe.

[0038] Furthermore, a connecting flange 2.2 is provided on the outer wall of the upper bend 2.1, and the connecting flange 2.2 is fixedly connected to the top plate of the main dust collection hood 1 by fixing bolts 10. This ensures the installation strength of the lifting auxiliary side suction mechanism 2.

[0039] Furthermore, the dust collection hood fixing frame 6 includes a first connecting rod 6.1 and a second connecting rod 6.4 that are parallel to each other. The front end of the first connecting rod 6.1 is hinged to the first hinge seat 6.2 on the connecting pipe 3, the tail end of the first connecting rod 6.1 is hinged to the second hinge seat 6.3 on the wall 11, the front end of the second connecting rod 6.4 is hinged to the third hinge seat 6.5 on the connecting pipe 3, and the tail end of the second connecting rod 6.4 is hinged to the fourth hinge seat 6.6 on the wall. An inclined support A12 and an inclined support B are respectively provided between the first connecting rod 6.1, the first hinge seat 6.2 and the wall 11.

[0040] Furthermore, the inclined support A12 includes a first screw hinged to the first connecting rod 6.1 and a second screw hinged to the wall 11. The other ends of the first and second screws are connected to a threaded tube, and the threads of the first and second screws have opposite directions. The threaded tube has a handle. The operation steps of the inclined support A12 are the same as those of the inclined support B, and they need to be operated simultaneously. The operator rotates the handle to change the depth of the first and second screws inserted into the threaded tube. That is, rotating the handle clockwise, the first and second screws can be screwed into the threaded tube simultaneously; rotating the handle counterclockwise, the first and second screws can be screwed out of the threaded tube simultaneously. By changing the length of the two sets of inclined supports, the angle between the first connecting rod 6.1, the first hinge seat 6.2 and the wall can be adjusted, thereby adjusting the height of the main dust collection hood 1.

[0041] Furthermore, the dust removal and filtration module includes a cyclone separator 13, a bag filter 14, and an induced draft fan 15. The air inlet of the cyclone separator 13 is connected to the exhaust pipe 8, and the air outlet of the cyclone separator 13 is connected to the air inlet of the bag filter 14 through a first pipe. The air outlet of the bag filter 14 is connected to the air inlet of the induced draft fan 15 through a second pipe. The induced draft fan 15 is connected to an exhaust pipe. As this is conventional technology and to reduce design costs, this application does not modify the cyclone separator 13, the bag filter 14, or the induced draft fan 15.

[0042] The dust removal device for the sodium hyaluronate packaging workshop described in this utility model has a main dust collection hood positioned above the sodium hyaluronate packaging machine. After the dust removal and filtration module is activated, a negative pressure state is formed at the main dust collection hood. The dust-laden gas generated during the sodium hyaluronate packaging process enters the connecting pipe through the main dust collection hood, and then sequentially passes through the tee connector, canvas telescopic hose A, and exhaust main pipe before entering the dust removal and filtration module for treatment. This effectively reduces dust pollution in the sodium hyaluronate packaging workshop, effectively protecting the environment and the health of workers. Furthermore, this dust removal system has a simple structure, reducing production costs.

[0043] The dust removal device for the sodium hyaluronate packaging workshop described in this utility model, by adding a lifting auxiliary side suction mechanism, after opening the pneumatic gate valve, the lifting auxiliary side suction mechanism shares the same set of dust removal and filtration modules. The dust suction port of the lifting auxiliary side suction mechanism can be closer to the material feeding position of the sodium hyaluronate packaging machine, and more accurately target the position with more dust, thereby achieving the purpose of improving dust removal efficiency and reducing the cost of dust removal equipment.

[0044] The dust removal device for the sodium hyaluronate packaging workshop described in this utility model allows the operator to adjust the height of the main dust collection hood by rotating a handle, thereby changing the depth of the first and second screws inserted into the threaded tube, changing the length of the two sets of inclined supports, and adjusting the angle between the first connecting rod, the first hinge seat and the wall.
