Description

Technical Field

[0001] This utility model relates to the field of polyester textile sizing material conveying technology, specifically a metering and conveying device for polyester textile sizing materials. Background Technology

[0002] Polyester textile sizing agents are mainly composed of polyester resin and crosslinking agents. They can penetrate into the fiber to form a protective film, making the fiber surface smoother and more delicate, and resisting external damage and wear, thereby improving the strength and durability of the fiber.

[0003] As disclosed in application number 202420827104.9, a slurry conveying device includes a movable base, an aramid fiber mixing drum, a screw metering conveyor, a mixing and distributing drum, a mica slurry crushing drum, and a mixing and conveying drum. The mixing and distributing drum is installed in the middle of the movable base, and an output pump connected to the bottom of the mixing and distributing drum via a filter is installed on the movable base. This allows for a continuous and quantitative supply of fiber slurry and mica slurry through the screw metering conveyor and the mixing and distributing drum, preventing material sedimentation during production. First sliding seats are slidably provided at both ends of the movable base via guide rod grooves. The first sliding seat is equipped with an aramid fiber mixing drum, and the bottom of the aramid fiber mixing drum is connected to a spiral metering conveyor. The second sliding seat is equipped with a mica pulp crushing drum and a mixing and conveying drum via a bracket. This allows the output pump to output fine pulp after filtration through a filter to the paper machine for processing mica paper, enabling quantitative pulp delivery and management. However, it still has some shortcomings in actual use. It cannot clean the filter, which may cause excessive impurities to adhere and affect its conveying effect. In addition, it is inconvenient to clean the inner wall during use, as pulp may clog the holes and affect its cleaning effect. Utility Model Content

[0004] The purpose of this invention is to provide a metering and conveying device for polyester textile sizing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A metering and conveying device for polyester textile sizing agents, comprising a conveying box and an outer cover. The outer cover is located at the middle of the top of the conveying box, and a discharge pipe is located at the middle of the bottom of the conveying box. The bottom of the discharge pipe is connected to a conveying pipe via a flange, and a flow meter is installed on the conveying pipe. A metering pump is installed at the other end of the conveying pipe. A rotating pipe is located inside the outer cover corresponding to the middle of the conveying box, and the bottom end of the rotating pipe extends into the conveying box via a bearing. A filter cover facing downward and fitting against the bottom of the conveying box is located at the bottom of the rotating pipe inside the conveying box. An annular spray block is located on the outer side of the top of the rotating pipe inside the conveying box, and spray holes are evenly distributed on the bottom and outer side of the annular spray block. An annular block is located at the top of the inner side of the conveying box, and... The outer side of the annular block is provided with annular toothed blocks, and scrapers are provided on both sides of the bottom of the annular block. The top and bottom of the inner side of the scraper are provided with connecting rods, and the other end of the connecting rod at the bottom of the scraper is provided with an arc-shaped scraper blade. The inner side of the scraper blade is in contact with the filter cover, so that the conveying pipe is connected to the discharge pipe. The flow meter and metering pump are used together to measure the conveyed slurry, preventing too much or too little from being conveyed. During the conveying process, the internal slurry can be filtered by the filter cover, and the slurry impurities attached to the filter cover can be scraped off, which can prevent them from affecting the filtration and conveying effect. During the mixing process, the slurry may splash out and adhere to the annular spray block. When the first scraper blade rotates, the second scraper blade rotates synchronously to scrape off the slurry attached to the liquid outlet of the annular spray block, which can prevent blockage and affect the subsequent cleaning effect.

[0006] Preferably, the inner side of the scraper is uniformly provided with stirring rod 1, and the other end of the connecting rod at the top of the scraper is provided with an L-shaped scraper blade 2. The inner side of the scraper blade 2 is in contact with the annular spray block. The rotating tube between the annular spray block and the filter cover is uniformly provided with horizontal stirring rod 2, and the stirring rod 2 is uniformly provided with vertical support rods. The rotation of the rotating tube and the stirring rod 1 and stirring rod 2 on the inner side of the scraper can stir and mix the internal slurry, and cause the scraper to drive the connecting rod at the top to rotate, so that the connecting rod drives the scraper blade 2 to rotate and scrape off the impurities on the spray holes of the annular spray block.

[0007] Preferably, a feeding box is provided at the middle position on one side of the top of the conveying box, and a discharge pipe is provided at the bottom of the feeding box near one end of the conveying box. The discharge pipe at one end of the feeding box extends into the conveying box, so that the feeding box feeds the slurry into the conveying box, and the slurry in the conveying box is sent into the subsequent process by the metering pump, which facilitates the conveying of the slurry.

[0008] Preferably, the discharge pipe is wrapped with an insulation pipe, and both the air inlet and outlet of the insulation pipe are connected to an external insulation box, so that the insulation pipe can keep the discharge pipe warm and prevent the temperature from being too low during discharge, which would cause the slurry to adhere and block, affecting the discharge effect.

[0009] Preferably, the inner side of the annular spray block and the rotating tube are evenly provided with openings, and the rotating tube at the bottom of the annular spray block is provided with a partition. The rotating tube above the partition is provided with a liquid inlet pipe, and the top of the liquid inlet pipe in the rotating tube extends to the top of the outer cover, so that the liquid inlet pipe sends the cleaning liquid into the rotating tube, so that the cleaning liquid on the partition enters the annular spray block and can spray the interior.

[0010] Preferably, the side wall of the conveyor box corresponding to the annular toothed block is provided with an annular groove, and the inner side of the annular groove of the conveyor box is uniformly provided with sliding balls that fit against the annular toothed block, so that the sliding balls fit against the annular toothed block and rotate, making its rotation more stable.

[0011] Preferably, the top of the rotating tube inside the outer cover is provided with a gear ring, and a motor is provided on the outer cover on the side away from the feeding box below the gear ring. The output end of the motor extends through a bearing to a gear inside the outer cover, and the gear meshes with the gear ring.

[0012] Preferably, a support cover is provided on one side of the conveyor box corresponding to the position of the annular toothed block, and a second motor is provided at the middle position of the bottom of the support cover near the side of the conveyor box. The output end of the second motor extends into the support cover through a bearing and is provided with a second gear. The support cover and the side wall of the conveyor box corresponding to the second gear are both provided with slots, and the second gear meshes with the annular toothed block through the slots.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This metering and conveying device for polyester textile slurry drives the annular spray block to rotate together through the rotating tube. During the rotation and stirring, the connecting rod at the top of the inner side of the scraper can rotate in the opposite direction, causing the connecting rod to drive the second scraper to rotate and scrape off the slurry attached to the outside of the annular spray block. This can prevent the liquid outlet from being blocked and facilitate subsequent internal spraying and cleaning. During the stirring and mixing, the second motor can be started to drive the second gear on its shaft to rotate. The second gear drives the annular toothed block that meshes with it to rotate, causing the annular toothed block to drive the annular block to rotate. This causes the annular block to drive the connecting rod at the bottom of the inner side of the scraper to rotate together, causing the connecting rod to drive the first scraper to rotate in the opposite direction to the filter cover. This can scrape off the slurry attached to the outside of the filter cover and prevent the filter cover from being blocked, thus affecting its metering and conveying effect.

During conveying, the flow meter 26 and metering pump 24 can calculate the flow rate of the slurry to enable metering and conveying.

[0023] A rotating tube 6 is located inside the outer casing 2, corresponding to the middle position of the conveyor box 1. The bottom end of the rotating tube 6 extends into the conveyor box 1 via a bearing. A filter cover 12 is located at the bottom of the rotating tube 6, facing downwards and fitting against the bottom of the conveyor box 1. An annular spray block 17 is located on the outer side of the top of the rotating tube 6 inside the conveyor box 1. The bottom and outer side of the annular spray block 17 are evenly provided with spray holes. Openings are evenly provided between the inner side of the annular spray block 17 and the rotating tube 6. A partition 18 is located inside the rotating tube 6 at the bottom of the annular spray block 17. A filter cover 12 is located inside the rotating tube 6 above the partition 18.

[0024] In use, the motor 3 can be started to drive the gear 4 on its shaft to rotate. The gear 4 drives the gear ring 5 that meshes with it to rotate, which in turn drives the rotating tube 6 to rotate. The rotating tube 6 then drives the annular spray block 17 to rotate together. During the rotation and stirring, the connecting rod 15 at the top of the inner side of the scraper 14 can rotate in the opposite direction. The connecting rod 15 drives the scraper 23 to rotate and scrape off the slurry attached to the outside of the annular spray block 17, which can prevent the spray holes from being blocked. The scraper 14 also drives the stirring 20 to rotate in the opposite direction, making the internal mixing more uniform. When it is necessary to clean the inside, the external liquid inlet pipe can send the cleaning liquid into the rotating tube 6, and the cleaning liquid in the rotating tube 6 can enter the annular spray block 17 through the opening for internal spray cleaning.

[0025] The inner top of the conveyor box 1 is provided with an annular block 13, and the outer side of the annular block 13 is provided with annular toothed blocks 19. The bottom sides of the annular block 13 are provided with scrapers 14. The inner top and bottom of the scraper 14 are provided with connecting rods 15.

The output end of the motor 2 7 extends through the bearing to the support cover 8 and is provided with a gear 22. The support cover 8 and the side wall of the conveyor box 1 are provided with slots. The gear 2 22 meshes with the annular toothed block 19 through the slots.

[0026] When in use, the motor 27 can be started to drive the gear 22 on its shaft to rotate. The gear 22 drives the annular toothed block 19 that meshes with it to rotate, which in turn drives the annular block 13 to rotate. The annular block 13 drives the scraper 14 to rotate, which can scrape the slurry on the inner wall and drive the connecting rod 15 at the bottom of the inner side to rotate together. The connecting rod 15 drives the scraper 11 to rotate in the opposite direction to the filter cover 12, which can scrape off the slurry attached to the outside of the filter cover 12 and prevent the filter cover 12 from being blocked, thus affecting its conveying effect.

[0027] A horizontal stirring rod 21 is evenly provided on the rotating tube 6 between the annular spray block 17 and the filter cover 12, and a vertical support rod is evenly provided on the stirring rod 21.

[0028] When in use, the rotating tube 6 drives the stirring rod 21 and the support rod to rotate together, which can fully mix the slurry and prevent it from settling to the bottom;

[0029] A feeding box 16 is provided at the middle position on one side of the top of the conveying box 1, and a feeding pipe is provided at the bottom of the feeding box 16 near one end of the conveying box 1, and the feeding pipe at one end of the feeding box 16 extends into the conveying box 1.

[0030] When in use, the feeding box 16 conveys the slurry into the conveying box 1 for easy loading;

[0031] The discharge pipe 9 is wrapped with an insulation pipe 10, and the air inlet and outlet of the insulation pipe 10 are both connected to the external insulation box.

[0032] When in use, the insulation gas can be sent into the insulation pipe 10 by the external insulation box, so that the insulation pipe 10 can keep the discharge pipe 9 warm. This can prevent the temperature of the discharge pipe 9 from being too low, which would cause the slurry to adhere and block the inner wall and affect the discharge effect.

[0033] The side wall of the conveyor box 1 corresponding to the annular toothed block 19 is provided with an annular groove, and the inner side of the annular groove of the conveyor box 1 is uniformly provided with sliding balls that fit against the annular toothed block 19.

[0034] When in use, as the annular toothed block 19 rotates, the sliding ball inside the annular groove engages with it, making its rotation more stable.

[0035] In this embodiment, the slurry is fed into the conveying box 1 via the feeding box 16. Then, the motor 3 is started to drive the gear 4 on its shaft to rotate. The gear 4 drives the gear ring 5 that meshes with it to rotate, which in turn drives the rotating tube 6 to rotate. The rotating tube 6 then drives the stirring rod 21 and the support rod to rotate together, which can fully stir and mix the slurry and prevent it from settling. At the same time, the rotating tube 6 can also drive the annular spray block 17 and the filter cover 12 to rotate together. During the rotation and stirring, the motor 7 can be started to drive the... The gear 22 on its shaft rotates, which in turn drives the annular toothed block 19 that meshes with it to rotate. This causes the annular toothed block 19 to rotate, which in turn drives the annular block 13 to rotate. The annular block 13 then drives the scraper 14 to rotate, which in turn drives the stirring rod 20 to rotate together. This stirs the slurry and scrapes the slurry off the inner wall. Then, it drives the connecting rod 15 at the bottom of the inner side to rotate together. This causes the connecting rod 15 to drive the scraper 11 to rotate in the opposite direction to the filter cover 12, which can stir the slurry adhering to the outside of the filter cover 12. Scraping prevents the filter cover 12 from clogging and affecting its filtration effect. When it rotates, it can drive the scraper 23 connected to the other end of the top connecting rod 15 to rotate and scrape off the slurry adhering to the outside of the annular spray block 17, which can prevent the liquid outlet from being blocked. Before feeding, the external insulation box can send insulation gas into the insulation pipe 10, so that the insulation pipe 10 insulates the discharge pipe 9, which can prevent the temperature of the discharge pipe 9 from being too low, causing the slurry to adhere and block the inner wall, affecting the discharge effect. The slurry in the conveying box 1 is stirred. After mixing and filtration, the control valves in the metering pump 24, flow meter 26, and discharge pipe 9 can be activated to allow the slurry to enter the metering pump 24 through the discharge pipe 9 and conveying pipe 9. During conveying, the flow meter 26 and metering pump 24 can calculate the flow rate of the slurry to enable metering and conveying, which is convenient for subsequent processing. When it is necessary to clean the inside, the external inlet pipe can send the cleaning liquid into the rotating pipe 6, and the cleaning liquid in the rotating pipe 6 can enter the annular spray block 17 through the opening for internal spray cleaning.
