[0002] The liquid flow high temperature and high pressure dyeing machine is a dyeing device that processes dyes at high temperature and high pressure. Since particulate matter may be generated during the production process of dyes, and this particulate matter can cause uneven dyeing during the dyeing process, thus affecting the appearance of the product, a filtration device is required for filtration.

[0003] Chinese Patent Publication No. CN217324610U discloses a filtration device for a liquid flow high-temperature and high-pressure dyeing machine. The device includes a feeding box with an inner cavity. A filtration device is installed on the inner wall of the feeding box. The filtration device includes a filter assembly and a connecting block mounted on the filter assembly. The connecting block has a fixing hole, and a fixing groove communicating with the fixing hole is formed on its inner wall. The filter assembly includes a fixing rod, a fixing block, and a filter box. One side of the fixing rod is connected to the fixing block, and the end of the fixing block away from the fixing rod is connected to the filter box. The filter box has a carrying cavity, and filter holes are formed on the outer side of the filter box, with filter screens installed on the filter holes. This device can filter large particles in the dye, improving the dye quality, and also facilitates the removal of impurities.

[0004] However, traditional filtration devices suffer from the problem of particulate matter clogging the filter mesh during the filtration process, which can cause the flow rate to slow down or stop. In this case, it is necessary to unclog or clean the filtered particulate matter. However, whether unclogging or cleaning, it is necessary to pause the dye delivery, which affects the processing efficiency. Utility Model Content

[0005] The main purpose of this utility model is to provide a filtration device for a liquid flow high temperature and high pressure dyeing machine, which can effectively solve the problem in the background technology that the traditional filtration device causes the flow rate to slow down or stop due to the blockage of the filter mesh by particulate matter during the filtration process. At this time, it is necessary to unclog or clean the filtered particulate matter. However, unclogging or cleaning requires pausing the dye delivery, which affects the processing efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A filtration device for a liquid flow high-temperature and high-pressure dyeing machine includes a first tube and a second tube. Ear plates are fixedly installed on both sides of the first and second tubes, and the ear plates of the first and second tubes are connected by a bolt assembly. The bolt assembly consists of a bolt and a nut. The bolt passes through the two ear plates and is threadedly connected to the nut. A flow-draining structure is provided at the front of the first tube and the rear of the second tube. The flow-draining structure includes a flow-draining bend. The flow-draining bend is fixedly installed at the front of the first tube, and a valve is fixedly installed at the upper position of the outer side of the flow-draining bend.

[0008] As a further embodiment of this utility model, the first tube and the second tube form a filter tube, the center of the filter tube is spherically shaped and expands outward, and the two ends of the flow bend are respectively connected to the upper part of the filter tube and the spherical part.

[0009] As a further embodiment of this utility model, the inner walls of the first tube and the second tube are both fixedly connected to the inner side of the spherical position, and a filter ball is provided between the two first sealing plates and the second sealing plates. A handle is fixedly installed on the outside of the filter ball.

[0010] As a further embodiment of this utility model, a through-tube is provided on the outside of the first tube and the second tube near the center, and the handle passes through the through-tube.

[0011] As a further embodiment of this utility model, two grooves are formed on the opposite surfaces of the first tube and the second tube, and a sealing strip is placed inside each of the two grooves.

[0012] As a further embodiment of this utility model, the filter ball has a hollow interior and a dense mesh exterior, and a flow groove is provided at the vertical lower position of the filter ball.

[0013] The beneficial effects of this utility model are as follows:

[0014] By setting up filter balls in conjunction with two flow bends and valves, the flow direction can be adjusted in time if blockage or slow flow occurs during dye delivery, without the need for temporary shutdown for cleaning, thus avoiding affecting the work progress. Moreover, the flow bends ultimately deliver the dye to the filter balls for filtration, eliminating the need for additional filter materials.

[0015] By setting up a flow channel with a first pipe and a second pipe and a filter ball, after use, the water pipe can be connected to the bottom of the first pipe and the second pipe to achieve a backwashing effect, which is convenient for maintaining the filter ball. In addition, the filter ball can also be rotated by the handle during the process, thereby working with the first sealing plate and the second sealing plate to scrape off the particles remaining on its surface, making the cleaning more thorough.

The bolt passes through the two ear plates 3 and is threadedly connected to the nut. A flow-draining structure 5 is provided at the front of the first tube body 1 and the rear of the second tube body 2.

[0024] See Figure 1 and Figure 2Furthermore, the drainage structure 5 includes a drainage bend 6, which is fixedly installed at the front of the first pipe body 1. A valve 7 is fixedly installed on the upper part of the outer side of the drainage bend 6. The first pipe body 1 and the second pipe body 2 form a filter pipe. The center of the filter pipe is spherically oriented and expands outward. The two ends of the drainage bend 6 are respectively connected to the upper part of the outer side of the filter pipe and the spherical position. The inner walls of the first pipe body 1 and the second pipe body 2 are fixedly connected to the inner side of the spherical position. A filter ball 11 is provided between the two first sealing plates 8 and the second sealing plates 9. A handle 12 is fixedly installed on the outside of the filter ball 11.

[0025] Specifically, the top of the first tube 1 and the second tube 2, which are assembled by bolt assembly 4, are connected to the external dye delivery pipeline, and the bottom is connected to the feed port of the liquid flow high temperature and high pressure dyeing machine. When the dye passes through, it will be filtered by the filter ball 11. The filtered dye passes through the filter ball 11 and is discharged into the dyeing machine, while the particulate matter remains on the outside of the filter ball 11.

[0026] Example 2

[0027] See Figure 3 and Figure 4 Furthermore, based on Embodiment 1, the first tube 1 and the second tube 2 are provided with a through tube near the center of the outside, and the handle 12 passes through the through tube. The filter ball 11 is hollow inside and has a dense mesh outside. A flow groove 13 is provided at the vertical lower position of the filter ball 11.

[0028] Specifically, the handle 12 can be used to rotate the filter ball 11, so that the filtered particles can be scraped off through the first sealing plate 8 and the second sealing plate 9.

[0029] It should be noted that this utility model is a filtration device for a liquid flow high-temperature and high-pressure dyeing machine. In use, the first tube 1 and the second tube 2 are assembled into a filter tube using bolt assembly 4. The top and bottom ends of the filter tube are connected to the dye input pipe and the dyeing machine inlet, respectively. When the dye enters the filter tube, it is filtered by the filter ball 11. The filtered dye passes through the filter ball 11 and enters the dyeing machine. When blockage or slow flow occurs, one or two valves 7 can be opened, allowing the dye to re-enter the filter tube through the guide bend 6 and be filtered again by the filter ball 11. The filter can be used for emergency purposes or to increase the flow rate. During later maintenance, the water pipe can be connected to the bottom of the filter tube, and the two valves 7 can be opened. The water flows through the flow channel 13 into the interior of the filter ball 11, carrying the filtered residual particles out from the guide bend 6 and the top of the filter tube, thereby achieving the backwashing effect. During the backwashing process, the filter ball 11 can be rotated by the handle 12, and the residual particles on the surface of the filter ball 11 can be scraped off by the first sealing plate 8 and the second sealing plate 9. The particles are discharged with the water flow, achieving the effect of cleaning the filter ball 11.
