Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of filter element cleaning, and relates to an automatic filter element cleaning device, in particular to an automatic high-pressure cleaning device for both the inside and outside of a filter element. Background Technique
[0002] A melt filter is an important device in high-speed spinning and fine denier filament spinning. It is used for continuous filtration of polymer melt to remove impurities and unmolten particles in the melt, so as to improve the spinning performance of the melt and ensure the spinning quality. The melt filter is commonly used in the spinning process, mainly for filtering impurities in the polyester melt at about 280 degrees Celsius to ensure the continuous progress of spinning. The filter element of the polyester melt filter is generally a cylindrical shape with a diameter of 6 cm and a length of 65 cm, and is composed of filter meshes with different mesh numbers. After the filter element is used for a period of time, its filtering performance deteriorates and it needs to be calcined and cleaned before it can be used again.
[0003] Due to its structural characteristics, the filter element needs to be cleaned on both the inside and outside during cleaning. The original inside and outside high-pressure cleaning mechanism, as Figure 1 shown, uses a relatively long inner lifting rod 105' to penetrate into the filter element 102' for inner flushing. This mechanism requires a large space to complete the cleaning during inside and outside high-pressure flushing. At the same time, due to the excessive length of the inner lifting rod 105', it is easy to touch the inner wall of the filter element when penetrating into the filter element 102', causing some damage to the filter element 102'. Moreover, when automatic handling and automatic cleaning of the filter element 102' are required, the huge space required by this inner lifting mechanism will not meet the requirements.

[0044] 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.
[0045] All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0046] In some embodiments, such as Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 8 shown, a device for automatically cleaning the inside and outside of a filter element is provided, which includes a cleaning tank 100, an internal high-pressure flushing assembly 200, a clamping cylinder 300, a rotating motor 400, and an external high-pressure flushing assembly 500. The internal high-pressure flushing assembly 200 and the clamping cylinder 300 are two groups, which are respectively installed at both ends of the cleaning tank 100 in cooperation with each other, and the rotating motor 400 is installed at one end of the cleaning tank.
[0047] There are two clamping push rods 202 on the internal high-pressure flushing assembly 200, which are respectively telescopically arranged at the left and right ends of the cleaning tank 100; and at least one end of the clamping push rod 202 is a hollow structure, which is hermetically connected to the inner cavity of the filter element 600 clamped between the two, and is used to clamp the filter element 600 from both ends and introduce high-pressure cleaning liquid into the filter element 600 to achieve the purpose of high-pressure flushing from the inside of the filter element 600.
[0048] The external high-pressure flushing assembly 500 includes a plurality of high-pressure nozzles 501 equidistantly installed on the front and rear inner side walls of the cleaning tank 100. The water inlets of the high-pressure nozzles 501 are respectively connected to the water inlet pipes 504, and each water inlet pipe 504 is externally connected to a high-pressure pump and a liquid storage tank, and is used to provide high-pressure cleaning liquid to each high-pressure nozzle 501 to achieve the purpose of high-pressure flushing the outside of the filter element 600.
[0049] In some of these embodiments, such as Figure 1 , Figure 4 , Figure 6 , Figure 7 and Figure 8 shown, the cleaning tank 100 is a square tank structure, and mounting plates 101 are respectively arranged on the side walls at the left and right ends thereof, and the internal high-pressure flushing assembly 200, the clamping cylinder 300, and the rotating motor 400.
[0050] Specifically, for the convenience of installing the clamping push rod 202 on the high-pressure flushing assembly 200, through holes 102 penetrating inside and outside are provided on the mounting plate 101 and the side wall of the corresponding cleaning tank 100, and the clamping push rod 201 is horizontally inserted into the through hole 102.
[0051] In addition, for the convenience of accurately positioning the filter element 600 in the cleaning tank 100, a filter element support frame 103 for placing the filter element 600 is provided at the bottom of the cleaning tank 100. Meanwhile, for the convenience of discharging the cleaning liquid, a drain pipe 104 is provided at the bottom of one end of the cleaning tank 100.
[0052] In some embodiments, as Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 shown, the inner high-pressure flushing assembly 200 is divided into two groups, which are respectively telescopically installed at both ends of the cleaning tank 100. Each group of the inner high-pressure flushing assembly 200 includes a guiding sleeve 201, a clamping push rod 202, a positioning end cap 203, and a limiting bearing 204, wherein:
[0053] Among them, the guiding sleeve 201 is vertically installed on the mounting plates 102 on both sides of the cleaning tank 100, and its inner hole is on the same axis as the through hole 101 on the mounting plate 102; the clamping push rods 202 at both ends are respectively a hollow tubular structure and a solid rod-like structure, which are movably inserted into the guiding sleeve 201, and their inner ends are located inside the cleaning tank 100. The guiding sleeve 201 mainly plays a guiding role, used to limit and install the clamping push rod 202 to prevent the clamping push rod 202 from shaking during the telescopic process.
[0054] To ensure the stability and sealing performance of clamping the filter element 600 and avoid liquid leakage during the cleaning process, the positioning end cap 203 is installed at the inner end of the clamping push rod 202. The positioning end cap 203 is a cap structure, provided with a sealing ring, and one end of the positioning end cap 203 and the inner hole of the hollow tubular structure are communicated with the inner hole of the clamping push rod 202.
[0055] To realize the linkage between the clamping cylinder 300 and the inner high-pressure flushing assembly 200, two limiting bearings 204 are used, which are sleeved on the outer periphery of the outer end of the clamping push rod 202 at intervals left and right, and a cylinder clamping block 303 on the clamping cylinder 300 is inserted and connected between the two limiting bearings 204. When the clamping cylinder 300 expands and contracts, the cylinder clamping block 303 at its front end slides along the axial direction of the clamping push rod 202, and can push the limiting bearing 204 in contact with it to drive the clamping push rod 202 to expand and contract synchronously, so as to clamp or loosen the filter element 600 from both ends.
[0056] Specifically, asFigure 3 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown in Figure 9 , in order to realize flushing high-pressure cleaning liquid into the inner cavity of the filter element 500 to be cleaned, a rotary seal sleeve 205, a flushing pipe 206 and a connecting flange 207 are further installed on the inner high-pressure flushing assembly 200 at one end of the cleaning tank 100. An external pressurized water pump is connected through the flushing pipe 206 and the connecting flange 207 to provide high-pressure cleaning liquid for the filter element 600.
[0057] Specifically, the inner end of the rotary seal sleeve 205 is connected to the clamping push rod 202. The clamping push rod 202 at this end side is a hollow tubular structure, and the inner cavity of the rotary seal sleeve 205 communicates with the inner hole of the hollow tubular clamping push rod 202; the inner end of the flushing pipe 206 is rotatably and sealingly installed at the other end of the rotary seal sleeve 205, and its outer end is fixedly connected to the connecting flange 207.
[0058] The inner cavity of the rotary seal sleeve 205 has a certain length, which can meet the sealing performance between the clamping push rod 202 and the flushing pipe 206 during the axial expansion and contraction of the clamping push rod 202. And the setting of the rotary seal sleeve 205 ensures its sealing performance with the flushing pipe 206 when rotating simultaneously with the clamping push rod 202, avoiding liquid leakage.
[0059] Specifically, as Figure 4 , Figure 5 , Figure 6 and Figure 8 shown, in order to cooperate with the rotary motor 400 to realize the rotation of the filter element 500 to be cleaned, a driven gear 208 is further installed on the inner high-pressure flushing assembly 200 at one end of the cleaning tank 100, and the clamping push rod 202 on the inner high-pressure flushing assembly 200 at this end can adopt a hollow tubular structure or a solid rod-shaped structure.
[0060] Preferably, the driven gear 208 is sleeved on the solid rod-shaped clamping push rod 202 between the guide sleeve 201 and the limit bearing 204 by a key connection and can slide axially for guiding.
[0061] During use, the clamping push rod 202 on the inner high-pressure flushing assembly 200 is driven by the clamping cylinders 300 at both ends to axially move leftward to clamp the filter element 600. Since the key connection between the clamping push rod 202 and the driven gear 208 constitutes a sliding guide, it does not affect its meshing connection with the driving gear 403. When the rotary motor 400 is started, the driving gear 403 at the upper end of the rotary motor 400 drives the clamping push rod 202 and the filter element 600 clamped by it to perform a rotating action through the driven gear 208.
[0062] It should be noted that the hollow structure of the clamping push rod 202 used in the jacket assembly 200 with the rotating seal sleeve 205, the flushing pipe 206 and the connecting flange 207 facilitates the introduction of high-pressure cleaning liquid. The clamping push rod 202 used in the jacket assembly 200 with the driven gear 208 at the other end adopts a solid rod-shaped structure. Of course, a hollow structure can also be adopted, but a sealing plug is required for plugging to maintain the high-pressure state of the cleaning liquid inside the filter element 500 to be cleaned, so that the cleaning liquid flows out from the inner cavity through the circumferential filter membrane to the outside of the filter element, realizing the purpose of backwashing the filter element from the inside to the outside.
[0063] In some of the embodiments, as Figures 2 to 9 shown, the automatic cleaning device further includes clamping cylinders 300 respectively installed at both ends of the cleaning tank 100, wherein: the clamping cylinders 300 are detachably installed on the mounting plate 101 on the side wall of the cleaning tank 100 through the cylinder fixing plate 301 at the front end and the cylinder fixing rods 302 arranged at its four corners; and a cylinder clamping block 303 with a Y-shaped structure is arranged on the telescopic rod at the front end of the clamping cylinder 300, and the open end of the cylinder clamping block 303 is inserted between the corresponding two limit bearings 204. Starting the clamping cylinder 300 can drive the clamping push rod 202 to perform axial telescopic movement through the cylinder clamping block 303.
[0064] In some of the embodiments, as Figure 4 、 Figure 5 and Figure 8 shown, the automatic cleaning device further includes a rotating motor 400 installed at one end of the cleaning tank 100, wherein: the rotating motor 400 is detachably installed on the mounting plate 101 on the side wall of the cleaning tank 100 through the motor fixing plate 401 at the front end and the motor fixing rods 402 arranged at its four corners; and a transmission gear 403 is installed on the output shaft at the front end of the rotating motor 400, and the transmission gear 403 is meshed and connected with the driven gear 208 sleeved on the upper limit of the inner high-pressure flushing assembly 200. Starting the rotating motor 400 can drive the clamping push rod 202 to rotate through the transmission gear 403 installed on its output shaft, so as to ensure that the circumference of the filter element 600 can approach the ultrasonic cleaning vibration head, thus ensuring the sufficiency of ultrasonic cleaning.
[0065] In some of the embodiments, as Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 8As shown, the external high-pressure flushing assembly 500 mainly includes high-pressure nozzles 501, locking nuts 502, fixed plates 503, and water inlet pipes 504. There are several high-pressure nozzles 501, which are respectively installed at equal intervals in the small holes on the front and rear inner side walls of the cleaning tank 100, and their tails pass through the small holes and are connected to the fixed plates 503. There are several locking nuts 502, which are respectively threadedly installed at the front ends of the high-pressure nozzles 501 to cooperate with the fixed plates 503 on the outside to fixedly install each high-pressure nozzle 501.
[0066] To ensure the stability of the installation of each high-pressure nozzle 501 on the front and rear walls of the cleaning tank 100, two fixed plates 503 are used, which are respectively fixedly installed on the outer walls of the front and rear side walls of the cleaning tank 100 and are fixedly connected to the tails of the high-pressure nozzles 501 on the same side. That is to say, the high-pressure nozzles 501 on the same side wall share one fixed plate 503 for fixed installation.
[0067] Corresponding to each high-pressure nozzle 501, there are several water inlet pipes 504, whose water outlets are respectively communicated with the tails of each high-pressure nozzle 501, and the water inlets are respectively connected to an external high-pressure water pump. The high-pressure water pump is connected to a water storage tank for supplying high-pressure cleaning liquid to each high-pressure nozzle 501.
[0068] In addition, it is worth noting that as Figure 8 shown, to improve the external cleaning effect of the external high-pressure flushing assembly 500 on the filter element 600, several high-pressure nozzles 501 are divided into two groups and installed in a front-back staggered manner. On the one hand, it improves the uniformity of the high-pressure flushing of the filter element 600 by the high-pressure nozzles 501, and on the other hand, it avoids the counter-flushing phenomenon of the high-pressure nozzles 501 arranged front and back relative to each other, thereby improving the external flushing effect of the filter element 600.
[0069] Combined with Figures 2 to 9 shown, the working principle of this filter element internal and external high-pressure automatic cleaning device is as follows: Place the filter element 600 to be cleaned on the filter element support frame 103 in the cleaning tank 100, start the clamping cylinders 300 at both ends to clamp and seal the filter element 600 to be cleaned; then use an external high-pressure pump to flush high-pressure cleaning liquid into the inner cavity of the filter element 600 to be cleaned through the flushing pipe 206 and the clamping push rod 202 to clean the filter element 600 from the inside; at the same time, turn on each high-pressure nozzle 501 on the external high-pressure flushing assembly 500 and start the rotating motor 400 to drive the filter element 600 to rotate, and use each high-pressure nozzle 501 to achieve a comprehensive flushing of the outside of the filter element 500; after the cleaning is completed, turn off the clamping cylinders 300 and the rotating motor 400, release the filter element 600, and complete the cleaning of the filter element 600. Replace the next filter element 600 to be cleaned and repeat the above steps.
[0070] In summary, compared with the existing internal and external flushing method, the outlet end of the filter element adopts an open structure. During high-pressure flushing, the internal lifting rod is relied on to penetrate into the inner cavity of the filter element, and the cleaning force of the high-pressure nozzle is used to sweep the filter element. The internal and external high-pressure automatic cleaning device for the filter element adopts the method of blocking the open end of the filter element, and the dirt on the filter element mesh holes is flushed out through a certain pressure, similar to a syringe, rather than using high-pressure water flow for sweeping; at the same time, it is combined with the external external high-pressure flushing component to realize the two-way flushing of the inside and outside of the filter element, the filter element is cleaned more thoroughly, and the cleaning efficiency is high; and the structure of the automatic cleaning device is reasonably designed and compact, saving a large amount of space, and can be well integrated into the automation equipment, rather than the internal and external high-pressure flushing being a huge complete machine, saving the production cost of the equipment.
