Description

Technical Field

[0001] This utility model belongs to the field of filter technology, and in particular relates to a pipeline-type multi-stage filtration device for adhesive production. Background Technology

[0002] A screw extrusion filter is a specialized filtration device for treating high-viscosity materials (such as colloids, slurries, and viscous liquids). It consists of a screw, motor, reducer, filter screen / filter cartridge, housing, inlet, outlet, and slag discharge port. Its working principle involves the screw's rotational motion propelling the material while simultaneously achieving solid-liquid separation using the filter screen or cartridge. During the extrusion and dehydration process, the liquid is further squeezed out, and ultimately, impurities are filtered out within the cartridge. This equipment features high-efficiency filtration, continuous operation, strong adjustability, energy saving and environmental friendliness, and a compact structure.

[0003] In actual production, a single filter cannot meet the requirements, as impurities can easily pass through, affecting the quality of the adhesive. Its filtration effect needs to be improved. Secondly, after the filter has been used for a certain period of time, it needs to be cleaned. The cleaning process involves stopping the equipment, removing the filter cartridge and cleaning it, and then reinstalling it. The above steps are not convenient and efficient. The production equipment must be stopped during the entire cleaning process, which affects production efficiency. Moreover, there are many adhesive production lines in the workshop, and the filter needs to be cleaned almost every few days.

[0004] To address the aforementioned issues, this application proposes a pipeline-type multi-stage filtration device for adhesive production. Utility Model Content

[0005] The purpose of this invention is to provide a pipeline-type multi-stage filtration device for adhesive production, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a pipeline-type multi-stage filtration device for adhesive production, including a filter body. Several filters are connected in series through a series pipe to form a multi-stage filtration group. A frame is installed at the bottom of the multi-stage filtration group. Telescopic moving mechanisms are provided on both sides of the bottom of the frame. The frame and the filtration group can be moved by the moving mechanisms. Two symmetrical support mechanisms are also provided in the middle of the bottom of the frame. The two support mechanisms are located in the middle of the two symmetrical moving mechanisms.

[0008] Furthermore, the frame includes a base at the bottom and several support frames supported on the base, as well as a tray fixed on the support frames, the top of which has an arc-shaped surface that matches the filter body.

[0009] Furthermore, the moving mechanism includes telescopic sleeves fixed to both sides of the bottom of the base and a telescopic rod slidably disposed in the telescopic sleeves. One end of the telescopic rod extends to the outside of the telescopic sleeve and is fixed with a caster wheel. The telescopic sleeve is provided with a locking plate for locking the telescopic rod in the telescopic sleeve.

[0010] Furthermore, the telescopic rod is provided with two locking grooves, and the two locking grooves on the two telescopic rods on the same side cooperate with each other. The locking plate is simultaneously inserted into one locking groove on both telescopic rods.

[0011] Furthermore, a locking cover for vertical movement of the locking plate is connected to the telescopic sleeve, and a handle is fixed to the top of the locking plate through the locking cover.

[0012] Furthermore, the support mechanism includes a right-angle plate welded and fixed to the middle of the side of the support frame, a long nut welded to the right-angle plate, and a long screw connected to the long nut by threads.

[0013] Furthermore, a pressure plate is rotatably connected to the bottom of the long screw, and a handwheel is welded to the top of the long screw.

[0014] This utility model has the following beneficial effects:

[0015] This invention uses a series of filter bodies connected in series to ensure that internal impurities are fully filtered out as the adhesive passes through the multiple filter bodies, thus ensuring the filtration effect. The pressure generated by the screw extruding the filter can ensure the flow rate of the adhesive and ensure production efficiency.

[0016] This utility model sets a frame below the multi-stage filter group, which can be easily moved by the moving mechanism at the bottom of the frame. Then, with a replacement group, when the filter group on a certain production line needs to be cleaned, the filter to be cleaned can be removed directly, and then the replacement group can be installed. Production can be started directly. The removed filter group becomes the replacement group, which can be cleaned to prepare for the next replacement, thus ensuring the efficiency of adhesive production.

[0017] This utility model combines a retractable moving mechanism and a support mechanism. The retraction of the moving mechanism ensures the stability of the filter group during movement and avoids occupying too much space after installation, thus increasing its flexibility. The support mechanism provides reinforcement at the bottom of the filter group after installation, ensuring its stability.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Please see Figure 1 - Figure 4As shown, this utility model is a pipeline-type multi-stage filtration device for adhesive production, including a filter body 1. Several filter bodies 1 are connected in series via a series pipe 2 to form a multi-stage filtration group. By connecting multiple filter bodies 1 in series, impurities in the adhesive are fully filtered out, ensuring filtration effect. At the same time, the pressure of the screw extrusion filter is used to ensure flow rate and improve production efficiency. A frame 3 is installed at the bottom of the multi-stage filtration group. The bottom of the frame 3 is provided with retractable moving mechanisms 4 on both sides. The frame 3 and the filtration group can be moved by the moving mechanisms 4. The frame 3 and the moving mechanisms 4 facilitate the movement and replacement of the filtration group. When cleaning is required, it can be quickly replaced with a spare filtration group to ensure production continuity. Two symmetrical support mechanisms 5 are also provided in the middle of the bottom of the frame 3. The two support mechanisms 5 are located in the middle of the two symmetrical moving mechanisms 4. The retractable design of the moving mechanisms 4 takes into account the stability of movement and space saving. Together with the support mechanisms 5, it enhances the stability of the filtration group after installation and improves the flexibility and reliability of the equipment.

[0029] The frame 3 includes a base 31 at the bottom and several support frames 32 supported on the base 31, as well as a tray 33 fixed on the support frames 32. The top of the tray 33 has an arc-shaped surface that matches the filter body 1. In this embodiment, a reinforcing rod is provided between the base 31 and the support frames 32 to support each other and ensure the strength of the filter assembly.

[0030] The moving mechanism 4 includes a telescopic sleeve 41 fixed on both sides of the bottom of the base 31 and a telescopic rod 42 slidably disposed in the telescopic sleeve 41. One end of the telescopic rod 42 extends to the outside of the telescopic sleeve 41 and is fixed with a universal wheel 43. The telescopic sleeve 41 is provided with a locking plate 44 for locking the telescopic rod 42 in the telescopic sleeve 41. In this embodiment, the two telescopic rods 42 on the same side move synchronously in opposite directions and cooperate with the telescopic sleeve 41 to achieve the purpose of telescopic extension on both sides.

[0031] The telescopic rod 42 is provided with two locking grooves 421. The two locking grooves 421 on the two telescopic rods 42 on the same side cooperate with each other. The locking plate 44 is simultaneously inserted into one locking groove 421 on the two telescopic rods 42. In this embodiment, the locking plate 44 and the locking groove 421 are provided with chamfers at the joint to facilitate insertion. One locking plate 44 can realize the synchronous locking of the two telescopic rods 42.

[0032] The telescopic sleeve 41 is connected to a locking cover 411 for the vertical movement of the locking plate 44. The top of the locking plate 44 passes through the locking cover 411 and is fixed with a handle 45. In this embodiment, the handle 45 facilitates the operation of the locking plate 44. In order to improve the downward pressing effect of the locking plate 44, a spring can be set at the connection between the locking plate 44 or the handle 45 and the locking cover 411. The spring enhances the pressing stability. When the locking plate 44 is inserted into the locking groove 421, at least a part of it is still located in the locking cover 411 to ensure the locking stability.

[0033] The support mechanism 5 includes a right-angle plate 51 welded and fixed to the middle of the side of the support frame 32, a long nut 52 welded to the right-angle plate 51, and a long screw 53 connected to the long nut 52 by threads. In this embodiment, the support mechanism 5 mainly avoids the middle from collapsing due to the long length of the filter group, and also avoids the overflow of glue at the connection between the two ends and the pipe due to the middle collapse when the filter group is connected.

[0034] The long screw 53 is rotatably connected to a pressure plate 54 at its bottom. In order to increase the friction with the ground after pressing, an anti-slip part can be set at the bottom of the pressure plate 54. A handwheel 55 is welded to the top of the long screw 53.

[0035] Understandably, this utility model effectively removes impurities from adhesives by connecting multiple filter bodies in series, ensuring filtration efficiency. Simultaneously, it utilizes the pressure of the screw extruding the filter to maintain flow rate and improve production efficiency. A frame and moving mechanism are installed below the multi-stage filter group, facilitating the movement and replacement of the filter group. When cleaning is required, it can be quickly replaced with a spare filter group, ensuring production continuity. The retractable design of the moving mechanism balances movement stability and space saving, while the support mechanism enhances the stability of the filter group after installation, improving equipment flexibility and reliability.

[0036] A specific application of this embodiment is as follows: multiple filter bodies 1 are arranged side by side and connected in the middle by a series pipe 2. The assembled filter group is placed on the frame 3 via a tray 33. The filter bodies 1 at both ends of the filter group are respectively connected to the inlet and outlet of the adhesive, forming a series passage. The state of the filter group after being connected to the delivery pipeline is as follows. Figure 1 As shown, the support mechanism 5 is in a supporting state at this time, and the moving mechanisms 4 on both sides are in a retracted state. The moving mechanisms 4 and the support mechanism 5 support the filter group at the same time.

[0037] Filter assembly replacement: Unfold and lock the moving mechanism 4, disengage it from the support mechanism 5, remove the flange connections at both ends of the filter assembly, move the frame 3 and the filter out using the casters 43, and replace the filter assembly with a clean one.

[0038] The use of the moving mechanism 4 is as follows: the locking plate 44 is lifted upward by the handle 45, and the locking plate 44 is simultaneously disengaged from the locking groove 421 at one end of the two telescopic rods 42. The telescopic rods 42 slide horizontally in the telescopic sleeve 41, the caster wheel 43 is extended or retracted, and then the locking plate 44 is simultaneously inserted into the locking groove 421 at the other end of the two telescopic rods 42.

[0039] The support mechanism 5 is used as follows: by rotating the long screw 53 through the handwheel 55, the pressure plate 54 moves up and down through the spiral of the long screw 53 and the long nut 52, so as to achieve the function of support and disengagement.
