Description

Technical Field

[0001] This utility model relates to the field of disperse dye preparation and production technology, and more specifically, to a pipe unblocking device. Background Technology

[0002] Disperse dyes are a class of dyes with relatively small molecules and no water-soluble groups in their structure. They can dye polyester fibers, acetate fibers, and polyamide fibers, making them a dedicated dye for polyester products. Pulping is the initial process step in the production of disperse dyes. Pulping produces a slurry with high viscosity. In actual production, it has been found that the discharge port of the pulping tank is most prone to clogging (generally due to decreased slurry flowability). Clogging at the discharge port significantly affects the normal output of slurry. Currently, each clogging requires manual disassembly and unclogging, which is time-consuming and labor-intensive. The company is considering designing and installing an automatic clogging auxiliary device to meet production needs. Utility Model Content

[0003] The purpose of this utility model is to address the needs of the prior art and provide a pipe blockage clearing device. One end of this utility model is connected to the discharge port of the slurry tank, and the other end is connected to the slurry discharge pipe. This utility model utilizes the connection between the first channel and the second channel to achieve normal slurry output, and can also meet the pipe blockage clearing needs by activating the clearing mechanism when a blockage occurs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A pipe unblocking device includes a body and an unblocking mechanism. The body has a first channel and a second channel, which are interconnected. A feed pipe seat is installed at the inlet end of the first channel, and a discharge pipe seat is installed at the outlet end of the second channel. The unblocking mechanism includes a piston, which is fitted into the first channel and can move along the length of the first channel. The piston is connected to a nitrogen pipeline. The movement of the piston toward the feed pipe seat can cut off the connection between the first channel and the second channel and open the outlet of the nitrogen pipeline.

[0006] Furthermore, the first channel is arranged horizontally, the second channel is arranged at an angle, and the upper end of the second channel is connected to the middle section of the first channel.

[0007] Furthermore, the unblocking mechanism also includes a central shaft and a piston-driven push cylinder. The central shaft is horizontally fixedly installed in the first channel, and the piston is fitted on the outside of the central shaft. The telescopic rod end of the piston-driven push cylinder is connected to the piston. Two air supply channels are opened in the piston body. The nitrogen pipeline is connected to the inlet of the air supply channel. An air outlet chamber is opened on the piston. The central shaft is fitted into the air outlet chamber. The outlet of the air supply channel is located on the side wall of the air outlet chamber. The movement of the piston toward the feed pipe seat can make the outlet of the air supply channel connect to the air outlet chamber.

[0008] Furthermore, the first channel includes a small diameter section and a large diameter section, the diameter of the small diameter section is smaller than the diameter of the large diameter section, the piston is installed on the large diameter section, the connection position of the first channel and the second channel is located on the large diameter section, and a forward stop is formed at the docking position of the small diameter section and the large diameter section.

[0009] Furthermore, a reset stop plate is fixedly connected to the outer wall of the central shaft.

[0010] Furthermore, the movement of the piston to contact the reset stop plate allows the central shaft to fill the exhaust chamber.

[0011] Furthermore, a side cover is fixedly installed on the opposite side of the feed tube seat of the device body, the piston-driven push cylinder is fixedly installed on the outside of the side cover, and a storage cavity is opened on the side of the device body where the side cover is installed.

[0012] Furthermore, the nitrogen pipeline includes a first pipe connector, a second pipe connector, and a hose. The first pipe connector is installed on the side cover, and the second pipe connector is installed at the inlet of the gas supply channel. The first pipe connector and the second pipe connector are connected by a hose.

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

[0014] 1. This utility model is installed in a pulping tank, with one end connected to the discharge port of the pulping tank and the other end connected to the slurry discharge pipe. When the first and second channels are connected, the utility model can output slurry normally. When the discharge port of the pulping tank becomes blocked, the utility model cuts off the first and second channels by activating the unblocking mechanism, and creates a backflow of high-pressure nitrogen gas in the direction of the discharge port of the pulping tank, thereby clearing the blockage and restoring the unobstructed flow of the discharge port.

[0015] 2. The structure of this utility model is reasonably designed, which can meet both the normal output of slurry and the need for unblocking pipes. After applying this utility model, general blockage problems can be quickly solved without disassembling the pipe. This utility model has the advantage of good application effect and is worth promoting and applying. Attached Figure Description

Detailed Implementation

[0020] 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 protection scope of the present utility model.

[0021] like Figures 1-3 The illustrated pipe unblocking device includes a body 1 and an unblocking mechanism 4. The body 1 has a first channel 11 and a second channel 12, which are interconnected to allow slurry flow. An inlet pipe seat 2 is installed at the inlet end of the first channel 11, and an outlet pipe seat 3 is installed at the outlet end of the second channel 12. Both the inlet pipe seat 2 and the outlet pipe seat 3 are equipped with flanges. In application, the inlet pipe seat 2 is connected to the outlet of the slurry tank, and the outlet pipe seat 3 is connected to the slurry outlet pipe. When the unblocking mechanism 4 is not in use, the first channel 11 and the second channel 12 are interconnected (e.g., ...). Figure 2 As shown), when the slurry is normally output through this invention, and a blockage occurs at the outlet of the slurry tank (judged by monitoring the flow rate at the outlet of the slurry tank), the unblocking mechanism 4 of this invention can be activated to perform unblocking operations. The unblocking mechanism 4 of this invention includes a piston 41, which is matched and installed in the first channel 11. The piston 41 can move along the length of the first channel 11. The piston 41 is connected to a nitrogen pipeline 5. Figure 3As shown, after the unblocking mechanism 4 is activated, the piston 41 moves toward the feed pipe seat 2, and the connection between the first channel 11 and the second channel 12 is cut off. The movement of the piston 41 opens the nitrogen delivery path, and the output port of the nitrogen pipeline 5 is opened. After high-pressure nitrogen is continuously fed into the nitrogen pipeline 5, it can form an impact of high-pressure nitrogen toward the feed pipe seat 2 (i.e., the direction of the discharge port of the slurry tank). This impact opens the blockage position and restores its smooth flow. The reason for using nitrogen is that it will not chemically react with the slurry during use. The input pressure of nitrogen is not less than 6 kg (0.6 MPa).

[0022] like Figure 2 As shown, in order to facilitate the movement and installation of the piston 41, the first channel 11 is arranged horizontally and the second channel 12 is arranged at an angle. The upper end of the second channel 12 is connected to the middle section of the first channel 11, so that the slurry can flow smoothly from the first channel 11 to the second channel 12.

[0023] like Figure 2 and Figure 3 As shown, to facilitate the installation of the unblocking mechanism 4, a side cover 13 is fixedly installed on the opposite side of the feed pipe seat 2 on the body 1 of this utility model. The side cover 13 is bolted together. After the side cover 13 is opened, the piston 41 can be installed. The unblocking mechanism 4 of this utility model also includes a central shaft 42 and a piston-driven push cylinder 43. One end of the central shaft 42 is fixedly connected to the side cover 13. The central shaft 42 is horizontally fixedly installed in the first channel 11. The piston 41 is fitted on the outside of the central shaft 42. During installation, the piston 41 is first inserted, and then the central shaft 42 is inserted into the piston 41 for installation. An air outlet chamber 412 is opened in the center of the piston 41. The central shaft 42 is fitted into the air outlet chamber 412. Figure 2 As shown, after initial installation, the central shaft 42 completely fills the exhaust chamber 412. The piston-driven push cylinder 43 is fixedly installed on the outside of the side cover 13. The telescopic rod end of the piston-driven push cylinder 43 is connected to the piston 41. The telescopic movement of the piston-driven push cylinder 43 can drive the piston 41 to move within the first channel 11. Two air delivery channels 411 are opened in the piston 41. The nitrogen pipeline 5 is connected to the inlet of the air delivery channel 411. The nitrogen pipeline 5 includes a first pipe joint 51, a second pipe joint 52, and a hose 53. The first pipe joint 51 is installed on the outside of the side cover 13, and the second pipe joint 52 is correspondingly installed at the inlet of the air delivery channel 411. The first pipe joint 51 and the second pipe joint 52 are connected by the hose 53. To ensure the air intake, there are two air delivery channels 411 in this utility model. Therefore, two sets of nitrogen pipelines 5 are configured to match. The outlet of the air delivery channel 411 is located on the side wall of the exhaust chamber 412. Figure 2As shown, during initial installation and normal slurry flow operations, the central shaft 42 is filled with the air outlet chamber 412. Therefore, the outlet of the air supply channel 411 is closed, and nitrogen cannot enter the interior of this utility model to avoid affecting normal slurry output operations. However, after the unblocking mechanism 4 is activated, the piston 41 is driven by the piston-driven push cylinder 43 to move towards the feed pipe seat 2. Since the central shaft 42 is fixedly installed, as the piston 41 moves to the left, the side of the air outlet chamber 412 facing the feed pipe seat 2 is gradually opened, and the outlet of the air supply channel 411 on the side wall of the air outlet chamber 412 is also opened. At this time, nitrogen is introduced, which can form a high-pressure nitrogen spraying effect in the air outlet chamber 412. The high-pressure nitrogen spraying impact direction is towards the feed pipe seat 2, that is, towards the discharge port of the slurry tank, thereby impacting and unblocking the blockage position.

[0024] like Figure 2 and Figure 3 As shown, the piston 41 of this utility model needs to have its stroke limited during movement. Therefore, this utility model designs the first channel 11 to include a small-diameter section 111 and a large-diameter section 112. The diameter of the small-diameter section 111 is slightly smaller than the diameter of the large-diameter section 112. A forward stop 113 is formed at the joint position of the small-diameter section 111 and the large-diameter section 112. The piston 41 is installed on the large-diameter section 112 and moves along the length of the large-diameter section 112. The forward stop 113 is located on the forward path of the piston 41 moving towards the feed tube seat 2. The connection point between the first channel 11 and the second channel 12 is located on the large-diameter section 112. Figure 3 As shown, when piston 41 contacts forward stop 113, the connection between first channel 11 and second channel 12 is blocked by piston 41. At this time, the air outlet chamber 412 inside piston 41 is open on one side. Piston 41 also needs stroke limit during reset. In this invention, a reset stop plate 421 is fixedly connected to the outer wall of central shaft 42. When piston 41 resets and contacts reset stop plate 421, as shown... Figure 2 As shown, the first channel 11 and the second channel 12 are connected at this moment, and the central shaft 42 is filled with the gas outlet chamber 412. At this time, nitrogen cannot enter this utility model, and the nitrogen input can be turned off.

[0025] like Figure 2 and Figure 3 As shown, the device body 1 has a storage cavity 14 on the side of the side cover 13. The position of the storage cavity 14 corresponds to the installation position of the hose 53 of the nitrogen pipeline 5. The length of the hose 53 should meet the requirements of the piston 41's movement stroke. After the piston 41 is reset, the hose 53 is retracted and stored in the storage cavity 14.

[0026] This invention has the advantage of good application effect. General blockage problems (referring to blockage caused by flow) can be quickly solved without disassembling the pipe. If it is a completely solidified blockage, it still needs to be manually disassembled and cleared, but such cases are relatively rare. Timely clearing of general blockage problems can reduce the probability of complete blockage. This invention is currently applied to pulping tanks, but it can also be applied to other equipment that is prone to blockage.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
