Description

Technical Field

[0001] The invention relates to the technical field of water mist dust removal, in particular to a water mist dust removal sedimentation tank for chelate resin production. Background Art

[0002] Chelating resin is a polymer compound that can selectively chelate specific metal ions from a solution containing metal ions in the form of ionic bonds or coordination bonds. The resin is composed of a cross-linked polymer as a skeleton and connected with special functional groups. Chelating resin is a type of cross-linked functional polymer material that can form a multi-coordination complex with metal ions. The mechanism of metal ion adsorption by chelating resin is that the functional atoms on the resin react with the metal ions to form a stable structure similar to a small molecule chelate, while the adsorption mechanism of ion exchange resin is electrostatic action. Compared with ion exchange resin, chelating resin has a stronger binding force with metal ions. During the production and stirring process of chelating resin, a large amount of dust will be generated. Therefore, the dust is collected to avoid direct discharge, prevent dust from polluting the environment and endangering the health of workshop workers. In terms of water mist dust removal, reference can be made to the patent scheme with the existing patent announcement number CN218944662U. The problem is that only a single dust absorption can be completed, and the dust in the air is not completely purified.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The present invention guides the air flow to flow horizontally back and forth multiple times through multiple air guide integrations, so that the dust in the air flow is fully combined with the falling water mist, and the purified and adsorbed air meets the emission requirements. In addition, the number of working air guide integrations depends on the dust content in the air during emission. The work of the air guide integration will increase the workload of the driving source. Therefore, under the condition of meeting the air purification requirements, the present invention adjusts and selects the number of working air guide integrations through regulation.

[0016] 2. The present invention uses a roller brush to clean the filter cloth. After cleaning, the local filter cloth is conveyed and covered on the square tube. At this time, the air comes to the square tube after passing through the filter cloth. The amount of dust attached to the filter cloth can represent the dust content in the air. When the air passes through the filter cloth, the greater the dust content in the air, the more dust covers the filter cloth, and the air permeability of the filter cloth decreases. Furthermore, when the air passes through, it will drive the filter cloth to move. The present invention determines the number of working air guide integrations according to the translation distance of the filter cloth. Description of the Drawings

Detailed implementation manners

[0033] 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 technical solutions in 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.

[0034] Please refer to Figures 1 to 15 The present invention provides a technical solution: a water mist dust removal sedimentation tank for chelating resin production, including a water mist box 1. One side of the bottom of the water mist box 1 is communicated with a sedimentation tank 2 for retaining sewage, and the sewage in the water mist box 1 seals the flowing water plate holes opened on the shell between the water mist box 1 and the sedimentation tank 2. The other side of the bottom of the water mist box 1 is communicated with a sewage discharge pipe 3 for discharging sediment. A spray head 4 for water mist spraying is arranged on the top of the water mist box 1, and an air inlet pipe 5 for injecting dust-laden air is fixed on the side shell of the water mist box 1 below the spray head 4. An exhaust integration 6 for exhausting air is arranged above the sewage liquid level in the water mist box 1, and a regulation integration 8 is drivingly connected to one end of the exhaust integration 6. A plurality of air guide integrations 7 for conveying air flow are arranged vertically between the air inlet pipe 5 and the exhaust integration 6, and the heads and tails of adjacent two air guide integrations 7 are opposite to each other. The air flow is purified by the falling water mist by horizontally crossing between the two air guide integrations 7. A shaft tool 9 is drivingly connected between the air guide integration 7 and the regulation integration 8.

[0035] Refer to Figure 3 and Figure 4It is understood that the regulation integration 8 includes a main shaft 10 passing through one side housing of the water mist box 1, a long cylinder gear 11 fixed to one end of the main shaft 10, a sub-shaft group 12 drivingly connected between the long cylinder gear 11 and the exhaust integration 6, a row of split shafts 13 with different lengths drivingly connected to the shaft tool 9, and a shaft selection device 14 for adjusting and driving the row of split shafts 13. The shaft tool 9 includes a side position frame 15 fixed to the water mist box 1 and a plurality of longitudinal shafts 16 with different lengths supported by the side position frame 15. The bottom end of each longitudinal shaft 16 is correspondingly and vertically drivingly connected to a split shaft 13, and the top end of each longitudinal shaft 16 is correspondingly and drivingly connected to a gas guiding integration 7. The split shaft 13 and the longitudinal shaft 16 can achieve reverse driving through two bevel gears arranged at the docking position.

[0036] Reference Figure 5 and Figure 6 It is understood that the exhaust integration 6 includes a filter cloth 19 in the shape of a flat closed-loop belt body, an exhaust group 17 for exhausting air distributed in the filter cloth 19, a support frame group 18 for supporting the filter cloth 19, and a roller brush 20 for cleaning distributed on one side of the filter cloth 19. The exhaust group 17 includes a stationary box 22 in the shape of a square groove housing, a square box tube 21 sliding and telescoping at the notch of the stationary box 22, and a straight flat tube 23 fixedly communicated with one end of the stationary box 22. One end of the straight flat tube 23 passes through the housing of the water mist box 1 and extends to the outside of the water mist box 1.

[0037] The dust generated in the production of chelating resin is discharged to the outside along with the air flow, and then injected into the water mist box 1 through the air inlet pipe 5. Water mist is sprayed from the nozzle 4. The falling water mist adsorbs the dust in the air, and then falls into the sewage at the bottom of the water mist box 1. The purified air passes through the filter cloth 19 and is injected into the square box tube 21, and then is injected into the straight flat tube 23 through the stationary box 22 and discharged to the outside. The roller brush 20 continuously rotates to clean the dust falling on the outer surface of the filter cloth 19. If the dust content in the air is relatively high and the water mist adsorption is not complete, when the air passes through the filter cloth 19, the dust covers the filter cloth 19. The cleaning ability of the roller brush 20 is limited. Therefore, the influence of the dust covering the filter cloth 19 exists, that is, the air permeability of the filter cloth 19 is reduced due to the influence of the dust covering. During the process of the air flow passing through the filter cloth 19 and injecting into the stationary box 22, the impact of the air flow on the filter cloth 19 will cause the movement of the filter cloth 19, that is Figure 6The filter cloth 19 and the square box cylinder 21 in it move synchronously in translation. The square box cylinder 21 gradually inserts into the static box 22. After the square box cylinder 21 inserts into the static box 22 by a specified length, it will trigger the operation of the air guide assembly 7 at the top of the water mist box 1, controlling the dust airflow injected into the water mist box 1 to complete a horizontal round-trip flow. Compared with the dust airflow directly flowing downward to the filter cloth 19, the operation of one air guide assembly 7 increases the contact opportunities between the dust airflow and the descending water mist twice, so that the dust purification can be more thorough. If the dust content in the air is higher and the dust covers the filter cloth 19 severely, when the airflow passes through the filter cloth 19, the filter cloth 19 moves a longer distance in translation, and the square box cylinder 21 sinks deeper into the static box 22, which will cause more air guide assemblies 7 to work, increasing the number of horizontal flows of the dust airflow. Among the vertical row of air guide assemblies 7, from top to bottom, more air guide assemblies 7 will gradually be put into operation.

[0038] Reference Figure 6 Understand that the support frame group 18 includes a portal frame 25, a guide plate frame 24 fixed on the water mist box 1, two parallelly distributed rollers 27 supported on the portal frame 25, and an inner support cylinder 26 fixedly sleeved on the roller 27.

The double-action gear 38 is in meshing connection with the long barrel gear 11 on one side. The limit shaft 34 is movably sleeved in a through hole opened on the adjustment frame 36.

[0041] The forming group 37 includes a direction rod 41 fixed on the adjustment frame 36, a spring 42 sleeved on the direction rod 41, and a T-shaped block 40 contacted at one end of the spring 42. An intercepting block is fixed at the end of the direction rod 41 at the other end of the spring 42. The direction rod 41 slides through a round hole opened at one end of the T-shaped block 40. One end of the swing plate 35 is in meshing transmission connection with a row of teeth provided on the T-shaped block 40 through a fixed arc-shaped rack. A cross column is arranged on the adjustment frame 36 to slide through a square hole opened on the T-shaped block 40. One end of the double-action gear 38 is movably sleeved in a column hole opened on the T-shaped block 40 through a fixed shaft body.

[0042] The unit gear group 39 includes an L-shaped unit plate 43 fixed on the cross column of the adjustment frame 36, a unit shaft 44 supported on the L-shaped unit plate 43, and a unit gear 45 fixed at one end of the unit shaft 44. The double-action gear 38 is in contact meshing with the unit gear 45 through axial movement. The sub-shaft 13 and the unit shaft 44 are respectively movably sleeved in two through holes opened on the L-shaped unit plate 43. And the other end of the unit shaft 44 is in meshing transmission connection with a bevel gear fixed on the sub-shaft 13 through a fixed bevel gear.

[0043] The air guide assembly 7 includes a flat shaft 48 vertically driven at the top end of the longitudinal shaft 16, an integrated shaft 47 vertically driven at both ends of the flat shaft 48, a row of fan parts 49 driven at one side of each integrated shaft 47, and two U-shaped flat tubes 46 with opposite head and tail ports. The U-shaped flat tubes 46 are fixed on the inner wall of the water mist box 1. A row of fan parts 49 are distributed in each U-shaped flat tube 46. The flat shaft 48 is movably sleeved in a through hole opened on the side position frame 15. The transmission between the longitudinal shaft 16 and the flat shaft 48 can be realized through bevel gear transmission. And the transmission between the flat shaft 48 and the integrated shaft 47 can also be realized through bevel gear transmission.

[0044] The fan part 49 includes a fan frame 51 fixed on the inner wall of the U-shaped flat tube 46, a fan shaft 50 supported on the fan frame 51, and a fan 52 fixed at one end of the fan shaft 50. The other end of the fan shaft 50 is in meshing transmission connection with an annular bevel gear fixed on the integrated shaft 47 through a fixed bevel gear.

[0045] The main shaft 10 is externally connected to a driving mechanism in the prior art. The rotation of the main shaft 10 drives the long barrel gear 11, and then drives the auxiliary shaft 31 through the auxiliary gear 32. Next, the longitudinal worm 28 is driven by the dual-control shaft 30. The dual-control shaft 30 also drives the roller brush 20 to rotate, thereby cleaning the filter cloth 19. In addition, the longitudinal worm 28 drives a roller 27 to rotate, and the filter cloth 19 is conveyed by the rotation of the inner support cylinder 26.

[0046] Due to dust coverage, the air permeability of the filter cloth 19 is lower. The more serious the coverage, the longer the translational distance of the filter cloth 19 is impacted when the air flow passes through the filter cloth 19. That is, the square box cylinder 21 sinks deeper into the stationary box 22. The square box cylinder 21 is fixedly connected to the portal frame 25. The translation of the portal frame 25 will drive the L-shaped control plate 33. The translation of the L-shaped control plate 33 drives the swing plate 35 to swing. Then, the translation of the T-shaped block 40 drives the axial movement of the double-action gear 38. The longer the axial movement distance of the double-action gear 38, the more unit gears 45 it will mesh with. Each unit gear 45 corresponds to a power source of the air guide assembly 7. The long barrel gear 11 drives the double-action gear 38, and then drives the unit gear 45. The rotation of the unit gear 45 ultimately causes the air guide assembly 7 to work.

[0047] The working principle of the air guide assembly 7 is as follows: The rotation of the unit gear 45 drives the rotation of the unit shaft 44, and then drives the longitudinal shaft 16 through the split shaft 13. Next, the integrated shaft 47 is driven by the flat shaft 48, causing the two rows of fan parts 49 in the air guide assembly 7 to work for ventilation. In this way Figure 13 the air flow in it presents an S-shaped path flow under the transportation of the fan parts 49, that is, the number of horizontal flows of the air flow increases twice, and the probability of dust being adsorbed by the water mist falling between the two U-shaped flat pipes 46 is higher.
