Description

Technical Field

[0001] The utility model belongs to the technical field of filter element cleaning, and relates to a filter element cleaning device, in particular to a self-clamping rotary filter element self-cleaning device. Background Technique

[0002] The melt filter is an important device in high-speed spinning and fine denier filament spinning, used for continuous filtration of polymer melt, removing impurities and unmelted particles in the melt 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 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, composed of filter meshes with different mesh numbers. After the filter element is used for a period of time, its filtering performance decreases and it needs to be calcined and cleaned before it can be used again.

[0003] Moreover, in the filter element cleaning industry, due to the particularity of the filter element, the filter element needs to be ultrasonically cleaned. When the filter element is ultrasonically cleaned, the ultrasonic cleaning vibrator head needs to be very close to the surface of the filter element, and the filter element needs to make a rotational movement so that the outer peripheral surface of the filter element can be close to the ultrasonic cleaning vibrator head, thereby ensuring that the filter element can be fully ultrasonically cleaned. However, in the existing filter element cleaning, manual clamping and fixing of the filter element and manual rotation of the filter element are generally adopted, which are time-consuming and laborious, and the clamping of the filter element is unstable and easy to fall off, affecting the cleaning efficiency of the filter element. At the same time, the manual flipping speed is uneven, and there are easy ultrasonic cleaning dead corners on the surface of the filter element. Summary of the Utility Model

[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0038] Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0039] In some embodiments, as Figure 1 、 Figure 3 、 Figure 4 and Figure 6 shown, a self-clamping rotary filter element self-cleaning device is provided. The filter element self-cleaning device mainly includes a cleaning tank 100, and jacket assemblies 200, clamping cylinders 300 and rotary motors 400 assembled at both ends of the cleaning tank 100, and is used for clamping and fixing and rotating a filter element 500 to be cleaned in the cleaning tank 100.

[0040] Specifically, there are two groups of the jacket assemblies 200, which are respectively telescopically arranged at the left and right ends of the cleaning tank 100, and their inner ends are located inside the cleaning tank 100 and are used for clamping the filter element 500 to be cleaned. There are two groups of the clamping cylinders 300, which are respectively arranged at the left and right ends of the cleaning tank 100, and their telescopic rods are connected to the other ends of the jacket assemblies 200. The clamping cylinders 300 are respectively used to control the telescopic movement of the jacket assemblies 200 to clamp and fix the filter element 500 to be cleaned, and the clamping is stable and reliable.

[0041] To ensure that the outer peripheral surface of the filter element can approach the ultrasonic cleaning vibrator head, the rotating motor 400 is used to drive the filter element 500 to be cleaned to perform a rotational movement. The rotating motor 400 is arranged at one end of the cleaning tank 100, and the driving gear 403 on its output shaft is meshed with the driven gear 208 sleeved on the limiting sleeve of the jacket assembly 200. The filter element 500 clamped between the two jacket assemblies 200 is driven to rotate by the rotating motor 400 to ensure that the filter element can be fully ultrasonically cleaned and avoid ultrasonic cleaning dead angles on the surface of the filter element.

[0042] In some of the embodiments, such as Figure 1 , Figure 3 and Figure 4 shown, the cleaning tank 100 is a square tank structure, and mounting plates 102 are respectively arranged on the side walls at its left and right ends for fixedly mounting the jacket assembly 200, the clamping cylinder 300 and the rotating motor 400.

[0043] Meanwhile, to facilitate the installation of the clamping push rod 202 on the jacket assembly 200, mounting holes 101 penetrating inside and outside are formed on the mounting plate 102 and the corresponding side wall of the cleaning tank 100, and the clamping push rod 202 is horizontally arranged inside the mounting hole 101. In addition, to facilitate the discharge of the cleaning liquid, a drain pipe 103 is arranged at the bottom of one end of the cleaning tank 100.

[0044] In some of the embodiments, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 shown, there are two groups of the jacket assemblies 200, which are respectively installed at both ends of the cleaning tank 100. Each group of the jacket assemblies 200 includes a guiding sleeve 201, a clamping push rod 202, a positioning end cap 203 and a limiting bearing 204.

[0045] 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 mounting 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-shaped structure, and they are movably arranged inside the guiding sleeve 201, and their inner ends are located inside the cleaning tank 100. The guiding sleeve 201 mainly plays a guiding role, which is used to limit and install the clamping push rod 202 to avoid the clamping push rod 202 from shaking during the telescopic process.

[0046] To ensure the stability and sealing of the clamping of the filter element 500 to be cleaned 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 in a cap structure, is provided with a sealing ring, and one end of the positioning end cap 203 communicates with the inner hole of the hollow tubular clamping push rod 202.

[0047] To realize the linkage between the clamping cylinder 300 and the jacket assembly 200, two limiting bearings 204 are used and are sleeved on the outer periphery of the outer end of the clamping push rod 202 at left and right intervals, and the 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 synchronously drive the clamping push rod 202 to expand and contract, so as to clamp or loosen the filter element 500 to be cleaned from both ends.

[0048] In some of the embodiments, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown, to realize flushing high-pressure cleaning liquid into the inner cavity of the filter element 500 to be cleaned, the jacket assembly 200 further includes a rotary seal sleeve 205, a flushing pipe 206 and a connecting flange 207, and a pressurized water pump is externally connected through the flushing pipe 206 and the connecting flange 207.

[0049] The inner side end of the rotary seal sleeve 205 is connected to the clamping push rod 202, and its inner cavity communicates with the inner hole of the clamping push rod 202 with one end being a hollow tubular structure; the inner side end of the flushing pipe 206 is rotatably and sealingly installed in the inner cavity of the other end of the rotary seal sleeve 205, and its outer side end is fixedly connected to the connecting flange 207.

[0050] The inner cavity of the rotary seal sleeve 205 has a certain length, which can meet the sealing between the clamping push rod 202 during axial expansion and contraction and the flushing pipe 206, and the setting of the rotary seal sleeve 205 ensures the sealing between it and the flushing pipe 206 when it rotates simultaneously with the clamping push rod 202, avoiding liquid leakage.

[0051] In some of the embodiments, such as Figure 4 、 Figure 5 、 Figure 6 and Figure 8As shown, to cooperate with the rotary motor 400 to realize the rotation of the filter element 500 to be cleaned, the jacket assembly 200 further includes a driven gear 208. 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 key connection and can slide axially for guiding.

[0052] During use, the clamping push rod 202 on the jacket assembly 200 is driven by the clamping cylinders 300 at both ends to move axially to the left to clamp the filter element 500 to be cleaned. Since the key between the clamping push rod 202 and the driven gear 208 constitutes a sliding guide, it does not affect its meshing connection with the transmission gear 403. When the rotary motor 400 is started, the transmission gear 403 at the upper end of the rotary motor 400 drives the clamping push rod 202 and the filter element 500 clamped by it to perform a rotating action through the driven gear 208.

[0053] It should be noted that the hollow structure of the clamping push rod 202 of the jacket assembly 200 with the rotary seal sleeve 205, the flushing pipe 206 and the connecting flange 207 is convenient for introducing high-pressure cleaning liquid. The clamping push rod 202 of the jacket assembly 200 with the driven gear 208 at the other end can adopt a hollow structure, but it needs to be blocked by a sealing plug to maintain the high-pressure state of the cleaning liquid in the filter element 500 to be cleaned, so that the cleaning liquid flows out from the inner cavity through the peripheral filter membrane to the outside of the filter element, realizing the purpose of backwashing the filter element from the inside to the outside.

[0054] In some embodiments, such as Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown, a cylinder fixing plate 301 is installed at the front end of the clamping cylinder 300. The cylinder fixing plate 301 is detachably installed on the mounting plate 102 on the side wall of the cleaning tank 100 through the cylinder fixing rods 302 arranged at its four corners.

[0055] And a cylinder clamping block 303 is arranged on the telescopic rod at the front end of the clamping cylinder 300. The cylinder clamping block 303 has a Y-shaped structure. One end of it is fixedly installed on the telescopic rod by a nut, and the other end is inserted into the opening between the two limit bearings 204 of the corresponding jacket assembly 200. The clamping cylinder 300 drives the clamping push rod 202 to perform axial telescopic movement through the cylinder clamping block 303.

[0056] In some embodiments, such as Figure 4 、 Figure 5 、 Figure 6 and Figure 8As shown, a motor mounting plate 401 is installed at the front end of the rotary motor 400. The motor mounting plate 401 is detachably installed on the mounting plate 102 on the side wall of the cleaning tank 100 through motor fixing rods 402 arranged at its four corners.

[0057] A transmission gear 403 is installed on the output shaft at the front end of the rotary motor 400. The transmission gear 403 is meshed and connected with a driven gear 208 which is coaxially sleeved on the jacket assembly 200. The rotary motor 400 drives the clamping push rod 202 to rotate through the transmission gear 403 installed on its output shaft, so as to ensure that the whole circumference of the filter element 500 to be cleaned can approach the ultrasonic cleaning vibration head, thereby ensuring the sufficiency of ultrasonic cleaning.

[0058] In addition, as a specific embodiment, the jacket assembly 200, the clamping cylinder 300 and the rotary motor 400 are all in two groups, which are respectively installed at the left and right ends of the cleaning tank 100 in a centrosymmetric arrangement, and the clamping cylinder 300 and the rotary motor 400 are respectively located at the front and back sides of the corresponding jacket assembly 200. The setting of two groups of rotary motors 400 ensures the stability of the rotation of the filter element 500 to be cleaned.

[0059] Combined with Figures 1 to 8 As shown, the working principle of the self-clamping rotary filter element self-cleaning device is as follows: Place the filter element 500 to be cleaned on the bracket in the cleaning tank 100, start the clamping cylinders 300 at both ends to run, and the cylinder clamping blocks 303 at both ends move towards each other to push the clamping push rod 202 to clamp and seal the filter element 500 to be cleaned; Then, high-pressure cleaning liquid is flushed into the inner cavity of the filter element 500 to be cleaned through the flushing pipe 206 and the clamping push rod 202 to clean the filter element 500 to be cleaned from the inside; At the same time, start the rotary motor 400, and synchronously drive the filter element 500 to be cleaned to rotate through the clamping push rod 202, so that the outer peripheral surface of the filter element 500 to be cleaned can all approach the ultrasonic cleaning vibration head to realize the cleaning of the outside of the filter element 500 to be cleaned; After the cleaning is completed, close the clamping cylinders 300 at both ends, and the cylinder clamping blocks 303 drive the clamping push rod 202 to move outward to loosen the filter element 500 to be cleaned, and complete the cleaning of the filter element. Replace the next filter element 500 to be cleaned and repeat the above steps.

[0060] The self-clamping rotary filter element self-cleaning device uses a clamping cylinder to clamp and fix the filter element to be cleaned, and uses the hollow inner cavity of the jacket assembly to convey high-pressure cleaning liquid to realize the automatic flushing of the filter element to be cleaned. The filter element is fixed stably, ensuring the smooth progress of the filter element flushing; At the same time, the filter element to be cleaned is driven by a rotary motor to rotate at a constant speed to ensure the sufficiency of ultrasonic cleaning. The structure of this filter element self-cleaning device is reasonably designed and compact, and can realize the automatic clamping and fixing, automatic flushing and automatic rotation of the filter element, with high automation degree, excellent cleaning effect and good practicability.
