Description

Technical Field

[0001] This utility model relates to the field of hydraulic pulping technology, and in particular to a hydraulic pulping system that is odor-proof and toxic-proof. Background Technology

[0002] Hydraulic pulpers are key equipment in the pulp and paper industry, primarily used for breaking down raw materials such as waste paper, pulp boards, and damaged paper. Their core function is to efficiently separate fibers and impurities while preserving fiber strength and length. In actual production, intermittent hydraulic pulpers are a commonly used type in paper mills. Under current production conditions, intermittent hydraulic pulpers are typically installed on the ground, featuring a barrel-shaped outer shell with an opening at the top serving as the feed inlet. This inlet is above ground level and unsealed, requiring a forklift or conveyor to feed the raw materials. During high-speed operation, pulp is frequently ejected from the hydraulic pulper, contaminating the workshop. A large amount of water vapor mixture also escapes from the feed inlet, corroding the production workshop and other equipment. After the equipment is shut down, the pulp remaining in the hydraulic pulper ferments under the action of bacteria, producing toxic odors that pose a safety risk. Utility Model Content

[0003] In view of the problems of inconvenient feeding and workshop pollution caused by pulp, water vapor and odor in the existing technical solutions due to the feed inlet being higher than the ground and without a cover, this utility model provides an odor-proof and toxic hydraulic pulping system.

[0004] This utility model provides the following technical solution: an odor-proof and toxic-proof hydraulic pulping system, comprising a hydraulic pulper with a feed inlet at the top, and further comprising: A pit is provided, and a hydraulic pulper is installed inside the pit. The bottom of the pit is sloped, and a water collection tank is provided at the lowest point of the pit. The water collection tank is equipped with a sewage pump. A support plate is provided to cover the top opening of the pit. The pit is also equipped with a blower, and the blower is equipped with an air extraction pipe. The feed inlet is equipped with a door cover, which is hinged to a flip cover. A telescopic rod is hinged between the flip cover and the hydraulic pulper or the door cover. The door cover is also equipped with a water inlet pipe and a steam exhaust pipe, and the steam exhaust pipe is connected in sequence to a blower and a water-vapor separator.

[0005] Preferably, the height of the feed inlet is lower than or flush with the support plate.

[0006] Preferably, the door cover is a truncated cone shape, the door cover includes a semi-circular top plate and a side plate connected between the edge of the semi-circular top plate and the feed inlet, the flip cover includes a first cover plate and a second cover plate, the first cover plate and the second cover plate form a V shape, and the first cover plate is hinged to the semi-circular top plate.

[0007] Preferably, a reinforcing rib is provided between the first cover plate and the second cover plate.

[0008] Preferably, both the water inlet pipe and the steam outlet pipe are located on the semi-circular top plate.

[0009] Preferably, a one-way valve is also provided on the pipe connecting the fan to the water-vapor separator.

[0010] The beneficial effects of this utility model are: by installing the hydraulic pulper in the pit and lowering the height of the feed inlet to be flush with or lower than the support plate, the raw materials can be directly pushed into the feed inlet from the support plate, making feeding more convenient and cost-effective, and solving the problems of sewage and odor; by setting a door cover and a flap at the feed inlet, the feed inlet can be closed during operation to prevent pulp splashing, and the extracted water vapor is discharged as dry gas after being treated by a water vapor separator.

Detailed Implementation

[0014] The embodiments of this utility model will be described in more detail below with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement them after reading this specification. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0015] This invention improves upon existing vertical intermittent hydraulic pulpers by providing an odor-proof and toxic-proof hydraulic pulping system.

[0016] Please refer to Figure 1A pit 10 is set in the workshop floor. A support plate 11, which can be made of steel plate, is installed at the top opening of the pit 10 to cover the top opening. A blower 12 is also installed in the pit 10. The exhaust pipe of the blower 12 extends through the support plate 11 to the outside or to the waste gas treatment process. The bottom of the pit 10 is sloped, and a water collection tank 13 is set at the lowest point of the pit 10. A sewage pump 14 is installed in the water collection tank, and the pipe of the sewage pump 14 is connected to the wastewater tank. The blower 12 can be a Roots blower, and the sewage pump 14 can be a submersible sewage pump.

[0017] The bottom of the pit 10 is also equipped with a raised section 15, which serves as the foundation for installing the hydraulic pulper 20. The hydraulic pulper 20 is installed inside the pit 10 to lower the height of the feed inlet, allowing it to be flush with or lower than the support plate 11. This allows raw materials to be directly pushed into the feed inlet from the support plate 11, avoiding the use of conveyors or forklifts and saving on feeding costs. Wastewater generated at the bottom of the hydraulic pulper 20 during production flows down the slope to the collection tank 13 and is discharged by the sewage pump 14. The support plate 11 covers the top opening of the pit 10, eliminating the safety hazard of workers falling in and using the blower 12 to extract odorous gases, creating a negative pressure environment that effectively prevents the spread of odorous gases produced by wastewater fermentation.

[0018] In the prior art, the hydraulic pulper 20 has a barrel-shaped outer shell 21, with the top opening of the barrel-shaped outer shell 21 serving as a feed inlet. This invention further includes a door cover 31 and a flip-top cover 32 at the feed inlet. Please refer to... Figure 2 The door cover 31 is a truncated cone shape, including a semi-circular top plate 311 and a side plate 312 connecting the edge of the semi-circular top plate 311 and the feed inlet. The flip cover 32 includes a first cover plate 321 hinged to the semi-circular top plate 311 and a second cover plate 322 connected to the first cover plate 321 in a V-shape. The first and second cover plates can seal the door cover 31 and the feed inlet. A telescopic rod is also hinged between the first cover plate 321 and the barrel-shaped outer shell 21. The telescopic rod can be pneumatically, hydraulically, or electrically driven. When it extends, it can lift the flip cover 32 to open the feed inlet. Reinforcing ribs are also provided between the first and second cover plates.

[0019] The semi-circular top plate 311 is also equipped with a water inlet pipe 33 and a steam exhaust pipe 34. Water is added to the hydraulic pulper 20 through the water inlet pipe 33, and the steam exhaust pipe 34 is connected in sequence to a blower 35 and a water-vapor separator 36. When the hydraulic pulper 20 is working, the flip cover 32 closes the feed inlet, the blower 35 extracts the generated water vapor, and sends it to the water-vapor separator 36 to remove the water vapor before discharge. A one-way valve is also installed on the pipe connecting the blower 35 to the water-vapor separator 36 to prevent water vapor backflow. The blower 35 can be an industrial exhaust fan.

[0020] The above describes one or more embodiments of this utility model in a relatively specific and detailed manner, but it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
