Description

Technical Field

[0001] The present invention relates to the technical field of dust gas treatment, and particularly relates to a dust gas treatment device for woven bag production. Background Art

[0002] During the production of woven bags, a large amount of dust is generated. If this dust remains in the workshop without being processed in time, it will cause harm to the physical health of the staff. Currently, in existing dust gas treatment devices, the adsorption medium for adsorbing dust is generally an electrostatic adsorption membrane. When air flows through the electrostatic adsorption membrane, the membrane adsorbs dust through electrostatic action to achieve dust removal. To improve the dust removal effect, a labyrinth structure is usually adopted to extend the contact time between air and the electrostatic adsorption membrane. However, the labyrinth structure easily causes dust to deposit inside the pipeline, requiring frequent shutdowns for cleaning, which reduces the overall efficiency. In view of the above problems, the present invention provides a dust gas treatment device for woven bag production. Summary of the Invention

[0003] Aiming at the above existing technical deficiencies, the purpose of the present invention is to provide a dust gas treatment device for woven bag production, which uses a spiral channel to extend the residence time of dust, combines an electrostatic adsorption membrane to significantly improve the dust removal effect, and at the same time, vibration cleaning can achieve dust discharge without shutdown for maintenance, without affecting the cleaning efficiency.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a dust gas treatment device for woven bag production, including: A box body, an air inlet pipe is provided at the upper end of the box body, an air outlet is provided at the lower end, and a blower is provided inside the air outlet. A dust suction component, which is installed inside the box body, and the upper end of the dust suction component communicates with the air inlet pipe, and is used for adsorbing dust particles in the air when air passes through. A dust collection box, which is installed inside the box body and is located below the dust suction component, and is used for collecting the dust particles discharged by the dust suction component.

[0005] Preferably, the dust suction component includes: A frame body, which is fixedly installed inside the box body, and the frame body is a cylindrical structure with an open lower end, and the upper side wall of the frame body communicates with the air inlet pipe; An electrostatic adsorption membrane, which is installed on the inner side wall of the frame body.

[0006] Preferably, a spiral air flow path is provided inside the frame body.

[0007] Preferably, a mounting shaft is coaxially provided inside the frame body, and a spiral plate is fixedly installed on the mounting shaft.

[0008] Preferably, the mounting shaft is rotatably mounted on the inner side wall of the frame body and is driven by a motor mounted on the frame body.

[0009] Preferably, the mounting shaft is inserted and cooperated with a support rod fixedly mounted on the inner side wall of the box body through a slot provided on its lower end surface.

[0010] Preferably, a plurality of bumps are provided on the support rod, and grooves adapted to the plurality of bumps are provided on the lower end surface of the mounting shaft; A prism is fixedly connected to the motor shaft of the motor, and a rib groove adapted to the prism is provided on the upper end surface of the mounting shaft.

[0011] Preferably, a rubber bladder is fixedly connected to the outer side surface of the spiral plate. A plurality of support elastic plates are provided inside the rubber bladder. One end of the support elastic plate away from the spiral plate inclines towards the rotation direction of the spiral plate and abuts against the rubber bladder, and the other three sides are fixedly connected to the inner side wall of the rubber bladder.

[0012] Preferably, the support rod is of a hollow structure and is communicated with an external air pump. The slot is communicated with the rubber bladder through the mounting shaft and the spiral plate, and the lower end of the rubber bladder is communicated with the outside.

[0013] Preferably, inside the air outlet of the box body, and on the upper and lower side surfaces of the inner side wall of the box body, a drainage rod and a collection frame are respectively fixedly connected. The drainage rod is communicated with an external water pump, the collection frame is communicated with an external water pool, and a water film is formed between the drainage rod and the collection frame during drainage.

[0014] The beneficial effects of the present invention are as follows: Through the settings of the frame body, the spiral plate and the electrostatic adsorption film, the present invention realizes the extension of the residence time of the dust-containing gas inside the frame body, enables the electrostatic adsorption film to better adsorb dust particles, and at the same time, since the dust-containing gas can generate centrifugal force during spiral movement, it accelerates the aggregation of dust towards the electrostatic adsorption film, further improving the adsorption efficiency of the electrostatic adsorption film.

[0015] Through the settings of the rubber bladder and the support elastic plates, the present invention realizes that gas can be pumped into the inside of the rubber bladder during rotation, causing the rubber bladder to expand and fit the inner side surface of the electrostatic adsorption film. At the same time, the elastic plates can generate a supporting force on the rubber bladder, making the cleaning effect of the rubber bladder better. In addition, the air entering the inside of the rubber bladder can be discharged through its lower end. Since the inclination direction of the elastic plates is opposite to the air flow direction, the abutting force of the elastic plates on the electrostatic adsorption film can be reduced, avoiding damage to the electrostatic adsorption film during the process of discharging dust. However, when dust is not discharged, the elastic plates abut against the electrostatic adsorption film, enabling the rubber bladder to better fit the electrostatic adsorption film and making the air flow only along the spiral trajectory.

[0016] Through the arrangement of the support rod and the bump, in the process of the motor driving the installation shaft to rotate, the installation shaft drives the spiral plate to vibrate up and down, so that the dust remaining on the spiral plate can be vibrated, and then the dust remaining on the spiral plate can be discharged more efficiently.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] The present invention provides a dust gas treatment device for woven bag production, as Figures 1 to 11 shown.

[0031] Embodiment 1: A dust gas treatment device for woven bag production includes a box body 1. An air inlet pipe is provided at the top of the box body 1, and an air outlet is provided at the bottom. A cylindrical frame body 3 is fixedly installed inside the box body 1. An opening is provided at the lower end of the frame body 3. The upper side wall of the frame body 3 communicates with the air inlet pipe. An electrostatic adsorption film 4 is adhered to the inner side wall. A fan is installed inside the air outlet. Starting the fan can make the outside air containing dust enter the inside of the frame body 3 through the air inlet pipe. At this time, the dust in the air is adsorbed by the electrostatic adsorption film, thereby performing dust removal work on the air entering the inside of the frame body 3. The air after dust removal is discharged through the air outlet.

[0032] To improve the dust removal effect, a spiral plate 6 is installed inside the frame body 3 through an installation shaft 5, forming a spiral air flow path inside the frame body 3. When the air containing dust enters the inside of the frame body 3, under the guiding action of the spiral plate 6, the air spirally flows inside the frame body 3, extending the contact time between the gas and the electrostatic adsorption film 4, enabling the electrostatic adsorption film 4 to better adsorb dust.

[0033] At the same time, the design of the spiral air flow path causes the dust-containing gas to form a swirl inside the frame body 3, and the dust is accelerated to move towards the electrostatic adsorption film 4 under the action of centrifugal force, which can further improve the adsorption efficiency.

[0034] Embodiment 2: On the basis of the first embodiment, in order to facilitate the cleaning of the dust adsorbed on the electrostatic adsorption film 4, the mounting shaft 5 is rotatably mounted inside the frame body 3. The upper end surface of the mounting shaft 5 is driven by a motor 7 mounted on the frame body 3. The mounting shaft 5 is inserted and matched with a support rod 9 fixedly mounted on the inner side wall of the box body 1 through a slot 8 provided on its lower end surface. Under the support of the support rod 9, the rotation of the motor shaft of the motor 7 can drive the mounting shaft 5 to rotate stably inside the frame body 3, so that the spiral plate 6 can scrape off the dust on the electrostatic adsorption film 4 and discharge it.

[0035] In order to prevent dust from remaining on the spiral plate 6 and not being discharged in time, a plurality of bumps 10 are fixedly connected to the support rod 9, and a plurality of grooves 11 adapted to the bumps 10 are provided on the lower end surface of the mounting shaft 5. When the mounting shaft 5 rotates, the bumps 10 and the grooves 11 cooperate with each other, enabling the mounting shaft 5 to drive the spiral plate 6 to vibrate up and down continuously, prompting the dust adhering to the spiral plate 6 to break away from the surface of the spiral plate 6. At the same time, since the spiral plate 6 rotates continuously during the up and down vibration, the fallen dust will generate a downward displacement on the surface of the spiral plate 6. Therefore, during the rotation and up and down vibration of the spiral plate 6, the dust adhering to the spiral plate 6 can be discharged better. A prism 12 is fixedly provided on the motor shaft of the motor 7, and a prism groove 13 adapted to the prism 12 is provided on the upper end surface of the mounting shaft 5. The prism 12 and the prism groove 13 are slidably connected. When the motor 7 is started, the mounting shaft 5 can be driven to rotate through the prism 12, and at the same time, it will not affect the up and down vibration of the mounting shaft 5.

[0036] In order to enable the spiral plate 6 to guide air better, a rubber bladder 14 is fixedly mounted on the outer side surface of the spiral plate 6 to better seal between the spiral plate 6 and the electrostatic adsorption film 4, so that air can only flow along the spiral plate 6. A support spring plate 15 is fixedly connected inside the rubber bladder 14. One end of the support spring plate 15 away from the spiral plate 6 is inclined towards the rotation direction of the spiral plate 6. At the same time, under the action of its own elastic force, the support spring plate 15 will make the rubber bladder 14 press tightly against the electrostatic adsorption film 4, so that air can flow along the spiral plate 6.

[0037] In order to prevent the spiral plate 6 from damaging the electrostatic adsorption film 4 during rotation and vertical vibration, which may affect the dust cleaning effect, the support rod 9 is designed as a hollow structure and is connected to an external air pump. The slot 8 is connected to the rubber bladder 14 through the mounting shaft 5 and the spiral plate 6. The lower end of the rubber bladder 14 is connected to the outside. The mounting shaft 5 is a hollow structure, and a communication groove is provided inside the upper end of the spiral plate 6. When the external air pump is started, air will enter the upper end of the rubber bladder 14 through the support rod 9, the slot 8, the mounting shaft 5, and the communication groove on the spiral plate 6, and finally be discharged through the lower end of the rubber bladder 14. When the air enters the inside of the rubber bladder 14, under the action of air pressure, the rubber bladder 14 will start to expand. At the same time, the air flow will push the support spring plate 15, making the inclination angle of the support spring plate 15 larger. At this time, the end of the support spring plate 15 away from the spiral plate 6 no longer presses the rubber bladder 14 against the electrostatic adsorption film 4. However, due to the expansion of the air, the rubber bladder 14 still presses against the electrostatic adsorption film 4, but the pressing force of the rubber bladder 14 against the electrostatic adsorption film 4 will become smaller. At this time, during the rotation and vertical vibration of the spiral plate 6, the rubber bladder 14 will undergo elastic deformation, playing a certain buffering effect to prevent the spiral plate 6 from damaging the electrostatic adsorption film 4 during rotation and vertical vibration.

[0038] One end of the support rod 9 located inside the slot 8 is fixedly connected with a rubber ring, which can prevent the air entering the slot 8 through the support rod 9 from leaking during the relative movement of the support rod 9 and the slot wall of the slot 8.

[0039] A dust collection box 2 is provided below the frame body 3. The dust collection box 2 is inserted into the inside of the box body 1. When discharging the collected dust, start the motor 7 to drive the spiral plate 6 to rotate and vibrate vertically while the air outlet internal fan is turned off. Under the action of the movement of the spiral plate 6, the dust inside the frame body 3 will fall into the inside of the dust collection box 2. Then, the dust collection box 2 can be taken out to clean the dust inside it.

[0040] Embodiment Three: On the basis of Embodiment Two, in order to make the dust cleaning effect better and avoid dust being discharged through the air outlet during dust cleaning, on the inner side of the air outlet of the box body 1 and on the upper and lower side surfaces of the inner side wall of the box body 1, a drainage rod 17 and a collection frame 16 are respectively fixedly installed. The drainage rod 17 is connected to an external water pump to spray water towards the collection frame 16 to form a continuous water film. When the dust-containing gas passes through the water film, the residual dust is adsorbed by the water, and the purified gas is discharged. The bottom of the collection frame 16 is connected to an external water pool, and the dust-containing waste water can be recycled after precipitation. The settings of the drainage rod 17 and the collection frame 16 can prevent dust from being discharged through the air outlet.

[0041] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
