Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection and air purification, and in particular relates to a dry filter paper box using a detachable filter back plate device. Background Art

[0002] Since the birth of Eisenmann's dry pure mechanical overspray mist particle separation system, after more than ten years of development, the newly built spray production lines on the market have basically replaced the Venturi wet spray particle separation system. The launch of the E-cube paper box dry filter system has a clean and tidy working environment, convenient and simple maintenance and replacement, and a significant separation efficiency of 0.5-2 mg / m3 of air, which is far lower than the 3 mg / m3 required by the Technical Guidelines for Air Quality Control (TA-Luft). In addition, compared with traditional wet water curtains, the dry overspray mist separation system can significantly reduce the energy consumption of air conditioning.

[0003] However, although the E-cube paper box dry filtration system performs well in many aspects, it has the problem of low utilization efficiency for special spray room designs and specific primer or topcoat characteristics. The application of conventional E-cube paper boxes under special paint properties may cause paint mist particles to quickly pass through the filter unit inside the paper box and block the filter bag unit on the back plate, reducing the net paint capacity of the paper box and the efficiency of the graded filter unit in absorbing paint particles, while causing serious blockage of the back plate filter cotton. This not only causes losses to customers, but also causes a huge waste of resources. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a dry filter paper box using a detachable filter back plate device, which can improve the filtration efficiency, simplify the replacement process, reduce maintenance costs, and extend the service life of the entire paper box.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A dry filter paper box using a detachable filter back plate device comprises a bottom paper tray, a cardboard outer cover shell is arranged on the top of the bottom paper tray, the cardboard outer cover shell is shaped as a cavity structure with both ends and one side open, and a tube bundle plate is symmetrically arranged inside the cardboard outer cover shell, and a filter cotton pipe net, a filter cotton wooden frame and a corrugated board are plugged on the tube bundle plate;

[0007] A detachable back panel device is provided at the side opening of the paperboard outer cover shell;

[0008] The detachable back panel device comprises a back panel outer protective paper shell, and a back panel wooden frame bracket is attached to the interior of the back panel outer protective paper shell;

[0009] The leeward side of the backboard outer protective paper shell is provided with a pressing plate I, a pressing plate II and a pressing plate III;

[0010] A baffle I and a baffle II are arranged on the windward side of the outer protective paper shell of the back plate, and a detachable filter unit is clamped on the outer protective paper shell of the back plate.

[0011] Furthermore, the pressing plate I and the pressing plate II are symmetrically arranged on the outer protective paper shell of the back plate, and the pressing plate III is rotatably connected to the back plate wooden frame bracket.

[0012] Furthermore, the baffle II is symmetrically distributed at both ends of the back panel wooden frame support, and the baffle I is arranged on the center line of the back panel wooden frame support.

[0013] Furthermore, the shape of the corrugated board is set to be a semicircular ring, and the corrugated boards are distributed in a relatively staggered manner.

[0014] Furthermore, the filter cotton wooden frame is located between the filter cotton pipe network.

[0015] Furthermore, glass wool is arranged on the filter cotton wooden frame.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] First, by adopting a detachable filter back plate device, the filtration efficiency and maintenance convenience are significantly improved. The system is favored for its high separation efficiency and easy maintenance. By incorporating a detachable filter unit, the utility model not only facilitates the rapid replacement of clogged or damaged filter materials, thereby maintaining continuous high-efficiency filtration performance, but also increases the economic benefits and service life of the entire system by reducing maintenance costs and time.

[0018] Secondly, the utility model increases the contact area between air and overspray mist and improves the filtration efficiency through the unique design of corrugated board and filter cotton pipe network. This design idea draws on the innovation of Eisenmann's dry pure mechanical overspray mist particle separation system in the background technology, and achieves a higher paint mist particle capture efficiency by optimizing the air flow path and increasing the contact area of ​​the filter material. This not only effectively improves the filtration performance, but also further enhances the economy and environmental friendliness of the system by reducing the replacement frequency of the filter material.

[0019] Finally, the structural design of the utility model, especially the addition of glass wool on the filter cotton wooden frame, specifically solves the problem of low efficiency of the E-cube paper box in special paint spraying environments mentioned in the background technology. The application of glass wool optimizes the adsorption performance of the filter unit, has excellent adsorption capacity for fine paint mist particles, and effectively extends the service life of the filter paper box. This improvement not only improves the filtration efficiency, but also ensures that when dealing with paint mist of special properties, the filtration system can maintain an efficient and stable operating state, maximizes the value of the filter unit, and reduces costs and increases efficiency for customers.

[0031] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0032] See also Figure 1-9 A dry filter paper box using a detachable filter back plate device comprises a bottom paper tray 5, a cardboard outer cover shell 1 is arranged on the top of the bottom paper tray 5, the shape of the cardboard outer cover shell 1 is set as a cavity-shaped structure with openings at both ends and one side, and a tube bundle plate 2 is symmetrically arranged inside the cardboard outer cover shell 1, and a filter cotton pipe network 4, a filter cotton wooden frame 6 and a corrugated board 7 are plugged on the tube bundle plate 2; a detachable back plate device 3 is arranged at the side opening of the cardboard outer cover shell 1; the detachable back plate device 3 comprises a back plate outer protective paper shell 15, and a back plate wooden frame bracket 12 is attached to the inside of the back plate outer protective paper shell 15; a pressing plate I9, a pressing plate II10 and a pressing plate III11 are arranged on the leeward side of the back plate outer protective paper shell 15; and a baffle I13 and a baffle II14 are arranged on the windward side of the back plate outer protective paper shell 15, and a detachable filter unit 8 is clamped on the back plate outer protective paper shell 15. The design is inspired by the high separation efficiency and easy maintenance of the E-cube carton dry filtration system mentioned in the background technology; it combines the innovative idea of ​​Eisenmann's dry pure mechanical overspray mist particle separation system, and achieves high-efficiency separation of air and overspray mist through the relatively staggered distribution of the tube bundle plate 2 and the corrugated board 7 inside the cardboard outer cover shell 1. At the same time, the glass wool on the filter cotton pipe network 4 and the filter cotton wooden frame 6 is used to perform secondary adsorption of paint mist to optimize the overall filtration performance.

[0033] See also Figure 5-7 , the pressing plate I9 and the pressing plate II10 are symmetrically arranged on the outer protective paper shell 15 of the back plate, and the pressing plate III11 is rotatably connected to the back plate wooden frame bracket 12. The design of the pressing plate is intended to ensure that the detachable filter unit 8 can be stably positioned inside the outer protective paper shell 15 of the back plate, and at the same time facilitate the user to easily remove and install a new filter unit when the filter unit 8 needs to be replaced; this design takes into account the problems of the difficulty of replacing the conventional E-cube paper box mentioned in the background technology and the high maintenance cost, and reduces the user's operation difficulty and maintenance cost by simplifying the replacement process.

[0034] See also Figure 5-7, baffles II14 are symmetrically distributed at both ends of the backboard wooden frame bracket 12, and baffles I13 are set on the midline of the backboard wooden frame bracket 12. The setting of baffles I13 and II14 further optimizes the positioning of the detachable filter unit 8 in the backboard outer protective paper shell 15, ensuring the stability and efficiency of the filter unit during the adsorption process; in addition, the design of the baffle is also based on the requirements of the background technology to improve the filtration efficiency and simplify the replacement process, and maximizes the use efficiency and life of the filter unit through precise positioning.

[0035] See also Figure 4 The shape of the corrugated plate 7 is set to be a semicircular ring, and the corrugated plates 7 are relatively staggered. This unique design not only increases the turbulence of air flow and improves the filtration efficiency, but also allows the paint mist particles to contact more with the corrugated plate 7 before passing through the filter cotton pipe network 4, thereby enhancing the adsorption effect; this design concept is based on the pursuit of high-efficiency filtration and long life in the background technology, and aims to achieve higher separation efficiency and longer service life by optimizing the air flow path and increasing the contact area of ​​the filter material.

[0036] See also Figure 2 and Fig. 9 , the filter cotton wooden frame 6 is located between the filter cotton pipe network 4. The setting of the filter cotton wooden frame 6 not only enhances the stability of the internal structure of the paper box, but also provides additional support for the filter material, optimizes the air flow path, and enables the passing air to be evenly distributed in the entire filter system; this design fully absorbs the advantages of the Eisenmann dry pure mechanical overspray mist particle separation system mentioned in the background technology, and further improves the filtration efficiency and the overall stability of the system through structural optimization.

[0037] See also Fig. 9 Glass wool is arranged on the filter cotton wooden frame 6. The application of glass wool not only has excellent adsorption capacity for fine paint mist particles, but also can effectively extend the service life of the filter paper box; this design is a targeted solution proposed after an in-depth analysis of the problem of low efficiency of the E-cube paper box in the background technology under special painting environment, aiming to solve the problem of special paint mist residue escaping to the back plate glass filter cotton by adding glass wool, a high-efficiency adsorption material, so as to optimize the performance of the entire filtering system.

[0038] The working principle of the utility model is:

[0039] When in use, air with overspray mist enters the interior of the cardboard outer cover shell 1 through the air inlet, and the air and the overspray mist are separated and adsorbed by the corrugated board 7 and the filter cotton pipe network 4. In this process, the filter cotton wooden frame 6 also plays a role in adsorbing the overspray mist and blocking part of the air from entering the rear half of the filter cotton pipe network 4;

[0040] The air then enters the detachable back panel device 3 and reaches the air outlet after passing through the detachable filter unit 8 .

[0041] When the detachable filter unit 8 on the detachable back panel device 3 is clogged or the filter cotton is torn, the paper box is pushed out of the work station, the screws and the pressure plate II10 are removed, the clogged detachable filter unit 8 is removed, and a new detachable filter unit 8 is replaced, the screws and the pressure plate II10 are installed and tightened, and the new detachable filter unit 8 is pushed into the work station to continue working.

[0042] By replacing the detachable filter unit 8 to solve the problem of back plate glass wool clogging, it is not only possible to effectively extend the life of the paper box and increase the net paint capacity of the paper box, but also to reduce costs and achieve better economic benefits.

[0043] By means of the baffle I13 and baffle II14, one side of the detachable filter unit 8 can be positioned, and by means of the pressure plates I9, II10 and III11, the other side of the detachable filter unit 8 can be positioned. When the detachable filter unit 8 needs to be replaced, it is only necessary to rotate the pressure plate III11 and then take out the detachable filter unit 8, thereby simplifying the replacement process of the detachable filter unit 8.

[0044] At the same time, the number of disassembled parts is reduced, the replacement process is simplified, and replacement is convenient; there are no protrusions on the detachable back panel device 3, which facilitates the stacking of parts during transfer and transportation.

[0045] The filter cotton wooden frame 6 and the glass wool arranged in the filter cotton wooden frame 6 row can slow down the abnormal increase of the wind pressure difference and the abnormal decrease of the air volume of the paper box, thereby extending the life of the paper box and increasing the net paint capacity; and can also slow down the escape of special paint mist residue to the back plate glass filter cotton.

[0046] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
