Description

Technical Field

[0001] The utility model belongs to the technical field of papermaking processing, and particularly relates to a semi-automatic conveying device for plate-type pulp pulping of base paper for vulcanized fiber. Background Technique

[0002] Vulcanized fiber is a kind of chemical synthetic fiber with high strength and good protective performance. The middle plate of vulcanized fiber cardboard has a certain thickness and has the characteristics of high wear resistance and fire prevention. In the papermaking process, raw materials such as wood, waste paper, and fibers are usually used to make pulp. These raw materials are chemically or mechanically treated to decompose them into a fibrous state to form pulp suitable for papermaking. The pulp is processed by a beater to further refine and evenly distribute its fibers. Subsequently, it is screened through a sieve to remove excess impurities, and then the screened pulp is pressed into a plate shape through a specific process to form a pulp board. Pulp breaking is the process of separating and refining the fibers in the raw materials. According to different raw materials, the pulp breaking methods are also different. Commonly used pulp breaking methods include mechanical pulp breaking and chemical pulp breaking.

[0003] After pulp breaking, the raw materials need to be transported to the next process. Some directly pulp the pulp through a pipeline. Since the fibers need to be separated and refined during the pulp breaking process, the direct transportation method is often not conducive to controlling the product quality and reducing the production effect. Content of the Utility Model

[0004] The utility model provides a semi-automatic conveying device for plate-type pulp pulping of base paper for vulcanized fiber, which has the characteristics of being able to detect the transportation of pulp in different regional positions, controlling the product quality of the transported pulp, and improving the production effect.

[0005] The utility model provides the following technical solution: A semi-automatic conveying device for plate-type pulp pulping of base paper for vulcanized fiber, including a pulp pulping machine. Both sides of the pulp pulping machine are hermetically connected with conveying pipes. A number of sampling and extending components are arranged on the conveying pipes. The sampling and extending components include sampling pipes, sampling mounting blocks, and sampling blocks. The sampling blocks are located inside the conveying pipes. A sealing disk hermetically connected to the sampling pipe is fixedly connected to the outside of the sampling blocks. Two telescopic rods for positioning the movement position of the sampling blocks are slidably connected inside the sampling mounting blocks. Sampling cavities are provided in the sampling blocks, and pressure disks are arranged above the sampling cavities.

[0006] Among them, the sampling pipes are hermetically connected to the conveying pipes, and the sampling mounting blocks are fixed at the tops of the sampling pipes.

[0007] Among them, the telescopic rods are slidably connected to the sampling mounting blocks, and a plug head for sealing the sampling cavity is inserted into the sampling blocks.

[0008] Among them, a pressure detection rod is fixedly connected to the top end of the pressure plate, a connecting cross bar is fixedly connected to the top end of the pressure detection rod, and a pressure sensor for detecting the pressure of the pressure plate is arranged on the pressure detection rod.

[0009] Among them, the telescopic rod is provided with a telescopic groove, and the connecting cross bar is slidably connected in the telescopic groove.

[0010] Among them, there are gaps between both sides of the pressure plate and both sides of the inner wall of the sampling cavity, and the slurry is extruded through the gaps.

[0011] Among them, the driving force of the pressure detection rod for driving the pressure plate is constant, and the pressure detection rod is slidably connected to the sealing plate.

[0012] The beneficial effects of the present utility model are as follows:

[0013] By setting the sampling extension assembly including a sampling tube, a sampling block and a sampling block, when the slurry is transported through the transport pipe after being broken, the transport can be stopped using a valve. At this time, the connecting cross bar can be pulled to make the sampling block leave the inside of the transport pipe. The slurry located in the sampling cavity can be pressed by the pressure plate, and the pressure detection rod can detect the change in pressure as it is pressed down. If there is unrefined slurry, the pressure will increase. At this time, the transport work needs to be stopped and the slurry needs to be processed continuously. By setting multiple sampling tubes, the slurry transported in different areas and positions can be detected to control the product quality of the transported slurry and improve the production effect.

[0014] The parts not involved in this device are the same as the prior art or can be implemented using the prior art. Description of the Drawings

[0020] Please refer to Figures 1-4, the present utility model provides the following technical solutions: It includes a slurry pulper 1, and conveying pipes 11 are hermetically connected to both sides of the slurry pulper 1. A number of sampling extension components 2 are provided on the conveying pipes 11. The sampling extension component 2 includes a sampling pipe 21, a sampling mounting block 22, and a sampling block 24. The sampling block 24 is located inside the conveying pipe 11. A sealing disk 243 that is sealed with the sampling pipe 21 is fixedly connected to the outside of the sampling block 24. Two expansion rods 23 for positioning the movement position of the sampling block 24 are slidably connected inside the sampling mounting block 22. A sampling cavity 241 is provided in the sampling block 24, and a pressure disk 25 is provided above the sampling cavity 241.

[0021] In this implementation: By providing the sampling extension component 2 including the sampling pipe 21, the sampling mounting block 22, and the sampling block 24, conveying pipes 11 are hermetically connected to both sides of the slurry pulper 1. The sampling block 24 is located inside the conveying pipe 11. When the slurry is being conveyed inside the conveying pipe 11, the slurry can be located inside the sampling cavity 241. A sealing disk 243 that is sealed with the sampling pipe 21 is fixedly connected to the outside of the sampling block 24. When the slurry is being conveyed through the conveying pipe 11 after being pulped, the conveying can be stopped using a valve. At this time, the connecting crossbar 27 can be pulled, and the expansion rods 23 move along the sampling mounting block 22, causing the sampling block 24 to move out of the conveying pipe 11. The slurry located inside the sampling cavity 241 can be pressed down using the pressure disk 25. There are gaps between both sides of the pressure disk 25 and both sides of the inner wall of the sampling cavity 241. The slurry is extruded through the gaps. When pressing down, the slurry will be extruded from the bottom of the pressure disk 25, and the slurry moves along the inner wall of the sampling cavity 241. A pressure detection rod 26 is fixedly connected to the top of the pressure disk 25, and a connecting crossbar 27 is fixedly connected to the top of the pressure detection rod 26. A pressure sensor for detecting the pressure of the pressure disk 25 is provided on the pressure detection rod 26. The pressure detection rod 26 can detect the change in pressure as it is pressed down. If there is unrefined slurry, the pressure that appears will increase. At this time, the conveying work needs to be stopped and the slurry needs to be processed continuously. By providing multiple sampling pipes 21, the slurry conveyed in different regional positions can be detected, the product quality of the conveyed slurry can be controlled, and the production effect can be improved.

[0022] The expansion rods 23 are slidably connected to the sampling mounting block 22, and a plug 242 for sealing the sampling cavity 241 is inserted into the sampling block 24; By opening the plug 242, the slurry inside the sampling block 24 can be discharged.

[0023] The expansion rod 23 is provided with a telescopic groove 231, and the connecting crossbar 27 is slidably connected inside the telescopic groove 231; The telescopic groove 231 and the connecting crossbar 27 cooperate to be able to position the position of the sealing disk 243.

[0024] The driving force for the pressure detection rod 26 to drive the pressure plate 25 is constant, and the pressure detection rod 26 is slidably connected to the sealing plate 243; the pressure detection rod 26 normally drives the pressure plate 25 under a certain pressure. When there is a pressure change, it can be analyzed whether the material is refined, and a spring member can be set to ensure that the pressure of the detection pressure plate 25 changes.

[0025] The working principle and usage process of the present utility model: When the slurry is being transported in the transport pipe 11, the slurry can be located in the sampling chamber 241. A sealing plate 243 that is sealed with the sampling pipe 21 is fixedly connected to the outside of the sampling block 24. When the slurry is transported through the transport pipe 11 after pulping, the valve can be used to stop the transport. At this time, the connecting crossbar 27 can be pulled, and the telescopic rod 23 moves along the sampling mounting block 22, so that the sampling block 24 moves out of the transport pipe 11. The slurry located in the sampling chamber 241 can be pressed down by the pressure plate 25. There are gaps on both sides between the pressure plate 25 and the inner walls on both sides of the sampling chamber 241. The slurry is extruded through the gaps. When pressing down, the slurry will be extruded from the bottom of the pressure plate 25, and the slurry moves along the inner wall of the sampling chamber 241. The pressure detection rod 26 is fixedly connected to the top of the pressure plate 25, and the connecting crossbar 27 is fixedly connected to the top of the pressure detection rod 26. A pressure sensor for detecting the pressure of the pressure plate 25 is provided on the pressure detection rod 26. The pressure detection rod 26 can detect the change in pressure as it is pressed down. If there is unrefined slurry, the pressure will increase. At this time, the transport work needs to be stopped and the slurry needs to be processed continuously. By setting multiple sampling pipes 21, the slurry transported in different areas and positions can be detected, the product quality of the transported slurry can be controlled, and the production effect can be improved.
