Abstract

This invention relates to a dust removal and separation device for insulation boards, comprising a housing with an internal multi-stage filtration system, a connecting pipe, a suction head assembly, an adsorption filter assembly connected to the mounting groove via a connector, a wedge block, a control rod, and a movable plate. The adsorption filter assembly has contact columns that cooperate with the movable plate. It also includes an inlet pipe and a waste outlet pipe connected to the connecting pipe, with the waste outlet pipe located between the wedge block and the connector plate. This invention drives the movable plate by manipulating the control rod. The movable plate, by pressing against and agitating the contact columns on the adsorption filter assembly, causes the adsorption filter assembly to shake, bend, or rotate slightly. This mechanical disturbance effectively shakes off excess dust accumulated on the surface and shallow layer of the adsorption pore structure, causing it to fall into the collection area below, thereby clearing the pores and significantly extending the effective adsorption time of the adsorption filter assembly, maintaining the continuous and efficient operation of the dust removal system.

Description

Technical Field

[0001] This invention relates to the field of dust removal technology for insulation boards, specifically a dust removal and separation device for insulation boards. Background Technology

[0002] A large amount of dust is generated during the production of insulation boards. Existing dust removal and separation devices typically treat the dust by combining negative pressure suction with multi-stage filtration. For example, Chinese Patent No. CN217939573U discloses a dust removal device for the production of vitrified microsphere insulation boards. Its basic principle is to use a blower to generate negative pressure, draw dust-laden air into the chamber, and purify it through a built-in multi-stage filtration device.

[0003] However, the aforementioned existing technical solutions have some shortcomings in practice. These are particularly evident in the operation and maintenance of the dust-adsorbing filter components, specifically:

[0004] The adsorption efficiency decreases over time. During operation, the filter element continuously adsorbs dust. When the amount of adsorbed dust increases but has not yet reached saturation, the dust may accumulate on the surface of the filter element, clogging its pore structure, which leads to a gradual decrease in adsorption efficiency and affects the continuous dust removal effect.

[0005] Therefore, a dust removal and separation device for insulation boards is proposed to address the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a dust removal and separation device for insulation boards.

[0007] The objective of this invention is achieved through the following technical solution: a dust removal and separation device for insulation boards, comprising a box with an internal multi-stage filtration device, and a suction head assembly connected to the box via a connecting pipe;

[0008] The connecting pipe has an installation groove, and an adsorption filter assembly is inserted into the installation groove through a connector. A wedge block is fixedly connected to the inner wall of the connecting pipe. A control rod that protrudes from the connecting pipe is movably fitted on the wedge block. A movable plate located between the wedge block and the adsorption filter assembly is fixedly connected to the control rod. The adsorption filter assembly has a contact post that cooperates with the movable plate.

[0009] It also includes an inlet pipe and a waste discharge pipe that are connected to the connecting pipe, with the waste discharge pipe located between the wedge block and the plug plate of the plug-in component.

[0010] Compared with the prior art, the advantages of the present invention are as follows:

[0011] The top of the adsorption filter assembly has an adsorption pore structure, and the plug plate is fixedly connected with elastic strips that press against the adsorption pore structure and are distributed in a longitudinal and transverse manner; the elastic support and conduction of the elastic strips enable the adsorption pore structure to produce more diverse deformations during cleaning, increasing the dynamic amplitude and frequency of dust removal, and having a stronger removal effect on dust stuck deep in the pores or adhering firmly, resulting in more thorough cleaning.

[0012] Furthermore, the elastic strips provide cushioning, distributing the concentrated force to the crisscrossing support points, effectively preventing the adsorption filter components from being damaged by stress concentration during frequent cleaning operations, thus extending their service life.

[0013] Compared with the prior art, the advantages of the present invention are as follows:

[0014] The connector includes an arc-shaped plate that is fixedly connected to the side of the connector plate. Both the connector plate and the arc-shaped plate are inserted into the mounting slot. A baffle that presses against one end of the connector plate is fixedly connected to the connecting pipe. The connecting pipe is also provided with a fixing component to fix the connector plate in the connector slot. The connector plate, the arc-shaped plate, and all the auxiliary components (adsorption and filtration components, etc.) installed on it are integrated into a whole module, realizing the whole plug-in installation and disassembly, which greatly simplifies the replacement and maintenance process. Moreover, the cooperation of the baffle and the fixing component ensures the accuracy and stability of the module installation position.

[0015] Compared with the prior art, the advantages of the present invention are as follows:

[0016] The fastener includes an elastic plate that is rotatably connected to the connecting pipe, and a groove that engages with the elastic plate at the other end of the plug plate; fastening and releasing can be completed with a simple rotation action, achieving second-level fast locking or unlocking.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] The top surface of the plug-in plate is provided with a plug-in groove for the bottom of the adsorption filter assembly to be inserted. The bottom of the adsorption filter assembly is a sealing plate. The sealing plate and the plug-in plate are installed through a shaking connector. When the movable plate acts on the contact column, the top of the adsorption filter assembly and the elastic strip are deformed under the action of the shaking connector. Through the lever or elastic mechanical principle, the limited stroke or torque of the movable plate is amplified into a larger deformation or vibration of the top of the adsorption filter assembly, thereby enhancing the dust removal kinetic energy.

[0019] Compared with the prior art, the advantages of the present invention are as follows:

[0020] The swaying connector includes a spring, with a plate fixedly connected to one end of the spring. A first slot is provided in the plate to connect to the other end of the spring, and second slots are provided on both sides of the sealing plate to engage with the plate. The plate and the spring rotate within the first and second slots respectively. On the one hand, the spring ensures that the adsorption filter assembly can automatically return to its initial position after the cleaning action is completed, preparing for the next cleaning. On the other hand, the elasticity of the spring and the movement gap of the plate in the slots together constitute a vibration system that can generate and absorb small amplitude vibrations. This not only amplifies the swaying effect during cleaning but also absorbs some of the impact, protecting the adsorption filter assembly from rigid collision damage.

[0021] Compared with the prior art, the advantages of the present invention are as follows:

[0022] The plug plate has a rotating groove on the side near the wedge block that communicates with the plug slot, and the movable plate rotates within the rotating groove.

[0023] Compared with the prior art, the advantages of the present invention are as follows:

[0024] An anti-overflow plate is fixedly connected to the wedge block above the movable plate. The top of the inlet pipe has an L-shaped structure and penetrates into the middle of the wedge block. The movable plate is positioned accordingly. The anti-overflow plate and the inlet pipe are positioned to prevent the rinsing liquid from entering the dry airflow channel.

[0025] Compared with the prior art, the advantages of the present invention are as follows:

[0026] The movable plate has clearance grooves at all four corners, and the side of the plug-in plate near the wedge block is chamfered.

[0027] As a further description of the above technical solution:

[0028] This application uses a control lever to drive a movable plate. By pressing against and agitating the contact columns on the adsorption filter assembly, the movable plate can cause the adsorption filter assembly (including its top adsorption pore structure) to shake, bend, or rotate slightly. This mechanical disturbance can effectively shake off excess dust accumulated on the surface and shallow layer of the adsorption pore structure, causing it to fall into the collection area below, thereby clearing the pores and significantly extending the effective adsorption time of the adsorption filter assembly, maintaining the continuous and efficient operation of the dust removal system.

[0029] Furthermore, the adsorption filter assembly and the plug-in plate are pre-assembled into an independent module via a wobbling connector consisting of springs and plug-in plates. This module is then inserted into the mounting slot of the connecting pipe as a whole, consisting of the plug-in plate and the arc-shaped plate. Attached Figure Description

[0045] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0046] like Figures 1-14 The diagram shows an embodiment of a dust removal and separation device for insulation boards provided by the present invention. It includes a housing 1 with an internal multi-stage filtration system. A suction head assembly 102 is connected to the housing 1 via a connecting pipe 101. In this application, a blower is located at the bottom of the housing 1 near the recycling bin. When the blower is activated, it generates negative pressure, causing suction to be transmitted to the suction head assembly 102 via the connecting pipe 101. This allows dust-laden air near the insulation board to be drawn in from the suction head assembly 102 and ultimately enter the housing 1 via the connecting pipe 101, where it is purified by the multi-stage filtration system. This method is a conventional technique in the prior art. For details on the specific structure and connections, please refer to the dust removal device for vitrified microsphere insulation board production in Chinese Patent Publication No. CN217939573U, which will not be elaborated upon here.

[0047] The connecting pipe 101 is provided with an installation groove 2, and an adsorption filter assembly 3 is inserted into the installation groove 2 through a plug-in connector. A wedge block 4 is fixedly connected to the inner wall of the connecting pipe 101. A control rod 5 that protrudes from the connecting pipe 101 is movably fitted on the wedge block 4. A movable plate 6 located between the wedge block 4 and the adsorption filter assembly 3 is fixedly connected to the control rod 5. The adsorption filter assembly 3 is provided with a contact post 7 that cooperates with the movable plate 6.

[0048] It also includes an inlet pipe 8 and a waste pipe 9 connected to the connecting pipe 101. The waste pipe 9 is located between the wedge block 4 and the plug plate 10 of the plug-in component. The other end of the inlet pipe 8 is connected to a conventional liquid supply system (including a storage tank, pump and delivery pipeline) to ensure that the liquid can be injected into the inlet pipe 8 stably and controllably. At the same time, the bottom of the waste pipe 9 works simultaneously with the liquid supply system through a solenoid valve.

[0049] The adsorption filter assembly 3 has an adsorption pore structure 301 on its top (the structure has a certain elasticity, such as polyurethane (PU) sponge or graphene aerogel). The plug plate 10 is fixedly connected with elastic strips 11 that press against the adsorption pore structure 301 and are distributed in a longitudinal and transverse manner. The elastic strips 11 provide support and pressure to specific areas of the adsorption pore structure 301 from below. When the movable plate 6 applies force to the adsorption filter assembly 3 through the contact column 7, this force will be further transmitted and dispersed through the deformation of the elastic strips 11, causing the adsorption pore structure 301 to produce more complex bending, twisting or local undulating movements.

[0050] The connector includes an arc-shaped plate 12 that is fixedly connected to the side of the connector plate 10. Both the connector plate 10 and the arc-shaped plate 12 are inserted into the mounting groove 2. A baffle 13 that presses against one end of the connector plate 10 is fixedly connected to the connecting pipe 101. The connecting pipe 101 is also provided with a fixing member that fixes the connector plate 10 in the connector groove 16. When replacing the adsorption filter assembly 3, the entire connector (including the adsorption filter assembly 3 on it) can be positioned as a module along the baffle 13, slide into or out of the mounting groove 2 as a whole, and be locked or unlocked by the fixing member.

[0051] The fastener includes an elastic plate 14 rotatably connected to the connecting pipe 101, and a groove 15 at the other end of the plug plate 10 that engages with the elastic plate 14. During installation, the plug is pushed into place, and then the elastic plate 14 is rotated, causing its elastic arm to engage in the groove 15 on the plug plate 10, forming a physical lock. During disassembly, simply rotate the elastic plate 14 in the opposite direction to disengage it from the groove 15, and the plug can be released and removed.

[0052] The top surface of the plug-in plate 10 in this application has a plug-in groove 16 for the bottom of the adsorption filter assembly 3 to be inserted. The bottom of the adsorption filter assembly 3 is a sealing plate 302. The sealing plate 302 and the plug-in plate 10 are installed through a wobbling connector. When the movable plate 6 acts on the contact post 7, the top of the adsorption filter assembly 3 and the elastic strip 11 deform under the action of the wobbling connector. The force exerted by the movable plate 6 on the contact post 7 is transmitted through the semi-rigid structure of the adsorption filter assembly 3, and finally produces a small relative movement or deformation at the wobbling connector. This floating connection method allows the top of the adsorption filter assembly 3 (carrying the adsorption pore structure 301) to bend or vibrate at a certain amplitude and angle relative to its connection point with the plug-in plate 10.

[0053] The swaying connector includes a spring 17, one end of which is fixedly connected to an insert plate 18. The insert plate 10 has a first slot 19 that connects to the other end of the spring 17. The sealing plate 302 has second slots 20 on both sides that are inserted into the insert plate 18. The insert plate 18 and the spring 17 rotate (make small-angle rotations) in the first slot 19 and the second slot 20 respectively. When the adsorption filter assembly 3 is subjected to an external force (through the contact column 7), the force is transmitted to the sealing plate 302 at its bottom. The insert plate 18 has a small space for movement in the second slot 20, which allows the spring 17 to be stretched, compressed or twisted, thereby allowing the adsorption filter assembly 3 to produce a swaying or deflecting motion within a limited range relative to the insert plate 10.

[0054] It is worth noting that the plug plate 10 has a rotating groove 21 that communicates with the plug groove 16 on the side near the wedge block 4. The movable plate 6 rotates in the rotating groove 21. This rotating groove 21 allows the movable plate 6 to change its posture between the vertical and horizontal planes around a control lever 5 when operating the control lever 5, such as rotating from the vertical standby state to the horizontal working state.

[0055] An overflow preventer 22 is fixedly connected to the wedge block 4 above the movable plate 6. The top of the liquid inlet pipe 8 has an L-shaped structure and penetrates into the middle of the wedge block 4, corresponding to the position of the movable plate 6. The cleaning liquid is introduced into the dust collection area between the wedge block 4 and the plug plate 10 through the liquid inlet pipe 8. The overflow preventer 22 acts like a small dam, preventing the mixed liquid level from rising above its height due to equipment vibration or liquid flow impact, thus preventing liquid from splashing upstream of the connecting pipe 101.

[0056] The four corners of the movable plate 6 are provided with clearance grooves 23, and the side of the plug plate 10 near the wedge block 4 is beveled to facilitate the sliding of dust and prevent excessive accumulation.

[0057] Regarding the sealing performance of this application: both the sides of the plug plate 10 and the sides of the arc plate 12 are provided with sealing layers. The sealing layers ensure the seal between the mounting groove 2 and the sides of the plug plate 10 and the arc plate 12, preventing air leakage.

[0058] Working principle: The suction head assembly 102 is brought close to the dust generated during the production of the insulation board. Through the cooperation of the blower, the suction head assembly 102 and the connecting pipe 101, the gas carrying dust is made to pass through the suction head assembly 102 and the connecting pipe 101.

[0059] When the dust-containing gas moves in the connecting pipe 101, the inclined guiding action of the wedge block 4 causes the dust-containing gas to pass through the adsorption pore structure 301 at the top of the adsorption filter assembly 3, and the dust is adsorbed by the adsorption pore structure 301.

[0060] Some dust falls from the adsorption pore structure 301 into the space between the plug plate 10 and the wedge block 4. Liquid can be slowly injected into the space between the plug plate 10 and the wedge block 4 through the liquid inlet pipe 8, thus ensuring that the liquid mixes with the dust and is easy to discharge from the waste discharge pipe 9. The bottom of the liquid inlet pipe 8 and the waste discharge pipe 9 are equipped with control valves. When liquid enters through the liquid inlet pipe 8, the valve of the waste discharge pipe 9 is opened at the same time, so that liquid inlet and waste discharge are carried out simultaneously, and the rates of liquid inlet and waste discharge are roughly the same. It is worth noting that the movable plate 6 is located at the top of the liquid inlet pipe 8 and the waste discharge pipe 9. Together with the anti-overflow plate 22, it prevents liquid from entering the connecting pipe 101 by passing over the sealing plate 302 and the wedge block 4.

[0061] When the adsorption pore structure 301 has adsorbed a large amount of dust (the adsorption pore structure 301 has not yet reached saturation), by rotating and pulling the control rod 5 back and forth (which can be operated manually), the movable plate 6 is made to rotate vertically between the plug plate 10 and the wedge block 4, and at the same time, it is moved horizontally to adjust its position. On the one hand, this moves the liquid, making it easier for the liquid to enter the waste discharge pipe 9; on the other hand, the movable plate 6 contacts the contact column 7 (the contact column 7 moves up and down), which presses against the adsorption pore structure 301, causing the adsorption pore structure 301 to bend slightly (at the same time, the elastic strip 11 bends at a certain angle), so that the excess dust adsorbed in the adsorption pore structure 301 falls into the space between the plug plate 10 and the wedge block 4.

[0062] It is worth noting that when the movable plate 6 is rotated to a horizontal state by rotating the control lever 5 (at which point the movable plate 6 is in contact with the contact post 7), the rotating lever is then pulled back and forth to keep the movable plate 6 in a horizontal state. This causes the movable plate 6 to drive the contact post 7 (which moves left and right) to rotate back and forth at a small angle of friction. This causes the adsorption pore structure 301 to rotate, which helps the adsorption pore structure 301 to bend and move, making it easier for dust to fall into the space between the plug plate 10 and the wedge block 4.

[0063] Explanation of the shaking of the sealing plate 302 in the insertion groove 16: Under the action of the spring 17, the end of the insertion plate 18 presses against the second slot 20 opened on the sealing plate 302. The width of the insertion plate 18 is smaller than the width of the second slot 20, and the first slot 19 has a conical structure. When the movable plate 6 presses against the contact post 7 (or the movable plate 6 moves to drive the contact post 7 to roll), the end of the insertion plate 18 presses against the second slot 20 and shakes at a certain angle in the vertical direction along the second slot 20. Meanwhile, the spring 17 shakes at a certain angle in the first slot 19.

[0064] When the adsorption pore structure 301 reaches saturation and needs to be replaced, first make the movable plate 6 vertical, then rotate the elastic plate 14 so that the elastic plate 14 overcomes the groove 15 and disengages from the groove 15. The elastic plate 14 rotates vertically downward. At this time, pull out the plug plate 10, and the plug plate 10, the arc plate 12, and the adsorption filter assembly 3 located on the plug plate 10 are taken out from the mounting groove 2.

[0065] Then the adsorption filter assembly 3 is removed from the insertion slot 16, that is, the sealing plate 302 is removed from the insertion slot 16, and the adsorption pore structure 301 is separated from the elastic strip 11.

[0066] Then, the new adsorption filter assembly 3 is reinstalled into the insertion slot 16, the insertion plate 18 is inserted into the second slot 20 of the sealing plate 302 of the new adsorption filter assembly 3, and the adsorption pore structure 301 of the new adsorption filter assembly 3 is attached to the elastic strip 11.

[0067] Finally, insert the plug plate 10 with the new adsorption filter component 3 into the mounting groove 2, the arc plate 12 is inserted into the mounting groove 2, and the elastic plate 14 is rotated so that the elastic plate 14 is re-inserted into the groove 15, thus completing the fixation of the position of the plug plate 10.
