Description

Technical Field

[0001] This utility model relates to the field of paper and plastic product manufacturing technology, and in particular to a top-level hot air recovery device for pulping paper and plastic products. Background Technology

[0002] During the waste paper pulping process, continuous heating can promote fiber swelling and dissociation, thereby optimizing pulping efficiency and improving fiber dissociation effect. At the same time, since the pulp viscosity is high at low temperatures, heating can also reduce the pulp viscosity, making it easier for pulp transportation and subsequent processing.

[0003] In existing technologies, hot air heating is mostly used when heating waste paper pulp. During the heating process, a hot air blower inputs hot air into the waste paper pulp through pipes. After exchanging heat with the waste paper pulp, the hot air enters the working environment through the top opening of the pulping cylinder. However, since the air still has a certain temperature after heat exchange, it will cause the working environment to heat up after entering the working environment, making the surrounding operators feel uncomfortable, and also causing energy waste.

[0004] Therefore, it is necessary to invent a top-level hot air recovery device for pulping paper and plastic products to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a top-level hot air recovery device for pulping paper and plastic products. This device can recover the waste gas after heat exchange, thereby avoiding the direct input of the waste gas into the working environment and causing the working environment to heat up. It is more convenient to use and can also realize the recovery of waste heat from the waste gas, thereby avoiding energy waste. This solves the problem mentioned in the background art that the airflow after heat exchange still has a certain temperature, which will cause the working environment to heat up after entering the working environment, making the surrounding operators feel uncomfortable and also causing energy waste.

[0006] According to one aspect of this disclosure, the following technical solution is provided: a top-layer hot air recovery device for pulping paper-plastic products, comprising:

[0007] A waste paper pulping mechanism, wherein the waste paper pulping mechanism is used to prepare waste paper pulp;

[0008] A movable sealing mechanism, used to seal the feed inlet of the waste paper pulping mechanism; and

[0009] The hot air circulation mechanism includes an air inlet pipe fixedly installed through the top right side of the pulping cylinder and extending to the bottom of the pulping cylinder's inner cavity. A heat-resistant diaphragm to prevent pulp backflow is fixedly installed inside the air inlet pipe. A hot air blower fixedly installed at the top of the pulping cylinder is fixedly connected to the input end of the air inlet pipe. The hot air circulation mechanism also includes an exhaust pipe fixedly installed through the top left side of the pulping cylinder. A purification box is fixedly connected to the output end of the exhaust pipe. An activated carbon filter is detachably installed inside the purification box. A circulation pipe is fixedly installed through the right side of the purification box and is connected to the output end of the hot air blower.

[0010] According to at least one embodiment of the present disclosure, a top-layer hot air recovery device for pulping paper and plastic products includes a pulping cylinder, a water inlet pipe is fixedly provided through the top back of the pulping cylinder, a one-way valve is provided on the water inlet pipe, and a support base is fixedly provided at the bottom of the pulping cylinder.

[0011] According to at least one embodiment of the present disclosure, a top-layer hot air recovery device for pulping paper and plastic products has a feed hopper fixedly installed inside the top feed inlet on the left side of the pulping cylinder, and a discharge pipe fixedly installed through the bottom right side of the pulping cylinder, with a discharge valve installed on the discharge pipe.

[0012] According to at least one embodiment of the present disclosure, a top-layer hot air recovery device for pulping paper and plastic products is provided, wherein a stirring shaft is rotatably nested inside the pulping cylinder via bearings, and a motor that is drively connected to the stirring shaft is fixedly provided at the top of the pulping cylinder.

[0013] According to at least one embodiment of the present disclosure, a top-layer hot air recovery device for pulping paper and plastic products includes a movable sealing mechanism comprising a U-shaped frame fixedly disposed on the top left side of the pulping cylinder cavity, wherein a movable plate is rotatably connected to the inner side of the U-shaped frame via a pin.

[0014] According to at least one embodiment of the present disclosure, a top-layer hot air recovery device for pulping paper and plastic products has an arc-shaped sealing plate fixedly disposed on the outside of the movable plate, and a sealing gasket layer is bonded to the outside of the arc-shaped sealing plate, the sealing gasket layer sealing the top feed port on the left side of the pulping cylinder.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This invention incorporates a hot air circulation mechanism. During the waste paper pulp preparation process, a hot air blower draws hot air into the waste paper pulp through an inlet pipe, heating the pulp and promoting fiber swelling and dissociation while reducing pulp viscosity. After heat exchange with the waste paper pulp, the hot air enters the top layer of the pulping cylinder cavity from within the pulp, then flows through an exhaust pipe into a purification chamber. An activated carbon filter inside the purification chamber absorbs water vapor from the exhaust gas. The exhaust gas is then returned to the hot air blower through a circulation pipe for reheating, and then reintroduced into the waste paper pulp through the inlet pipe. Compared to existing technologies, this invention can recover the heat-exchanged exhaust gas, preventing it from being directly introduced into the working environment and causing overheating. It is more convenient to use and also allows for the recovery of waste heat, thus avoiding energy waste. Attached Figure Description

[0028] Figure 3 This is a schematic diagram of the movable sealing mechanism 2 and the hot air circulation mechanism 3 of a top-layer hot air recovery device for pulping paper and plastic products according to one embodiment of the present disclosure.

[0029] like Figures 1-3 As shown, the top-level hot air recovery device for pulping paper and plastic products disclosed herein may include components such as a waste paper pulping mechanism 1, a movable sealing mechanism 2, and a hot air circulation mechanism 3.

[0030] like Figure 2 As shown in this disclosure, the waste paper pulping mechanism 1 includes a pulping cylinder 11. A water inlet pipe (not shown) is fixedly installed through the top back of the pulping cylinder 11. A one-way valve is installed on the water inlet pipe. A support base 12 is fixedly installed at the bottom of the pulping cylinder 11. A feed hopper 13 is fixedly installed inside the feed inlet on the top left side of the pulping cylinder 11. A discharge pipe 14 is fixedly installed through the bottom right side of the pulping cylinder 11. A discharge valve is installed on the discharge pipe 14. An agitator shaft 15 is rotatably nested inside the pulping cylinder 11 via bearings. A motor 16, which is connected to the agitator shaft 15, is fixedly installed at the top of the pulping cylinder 11.

[0031] Therefore, the crushed waste paper raw material is added into the pulping cylinder 11 through the feed inlet, and water is added into the pulping cylinder 11 through the water inlet pipe. The waste paper raw material and water are initially mixed inside the pulping cylinder 11. Then, the motor 16 is connected to an external power source. At this time, the motor 16 drives the stirring shaft 15 to continuously stir the waste paper raw material and water, thereby accelerating the decomposition of the waste paper raw material and the mixing of the decomposed waste paper raw material with water, and finally producing waste paper pulp.

[0032] like Figure 3 As shown, in a preferred embodiment, the movable sealing mechanism 2 includes a U-shaped frame 21 fixedly disposed on the top left side of the inner cavity of the pulping cylinder 11. A movable plate 22 is rotatably connected to the inner side of the U-shaped frame 21 via a pin. An arc-shaped sealing plate 23 is fixedly disposed on the outer side of the movable plate 22. A sealing gasket is bonded to the outer side of the arc-shaped sealing plate 23, and the sealing gasket seals the feed inlet on the top left side of the pulping cylinder 11.

[0033] Therefore, after the shredded waste paper is added to the inside of the feed hopper 13, the waste paper continues to slide down the inner wall of the feed hopper 13. As the amount of waste paper increases, it eventually pushes the arc-shaped blocking plate 23. The arc-shaped blocking plate 23 then drives the movable plate 22 to rotate around the pin on the U-shaped frame 21, thereby avoiding the waste paper and allowing it to enter the pulping cylinder 11 through the feed inlet.

[0034] It should be noted that if there is residual waste paper material inside the feed hopper 13, the arc-shaped sealing plate 23 can be manually pushed to avoid the residual waste paper material.

[0035] like Figure 3 As shown in this disclosure, the hot air circulation mechanism 3 includes an air inlet pipe 31 that is fixedly disposed through the top right side of the pulping cylinder 11 and extends to the bottom of the inner cavity of the pulping cylinder 11. A heat-resistant valve to prevent pulp backflow is fixedly disposed inside the air inlet pipe 31. A hot air blower 32 fixedly disposed at the top of the pulping cylinder 11 is fixedly connected to the input end of the air inlet pipe 31. The hot air circulation mechanism 3 also includes an exhaust pipe 33 that is fixedly disposed through the top left side of the pulping cylinder 11. A purification box 34 is fixedly connected to the output end of the exhaust pipe 33. An activated carbon filter screen is detachably disposed inside the purification box 34. A circulation pipe 35 is fixedly disposed through the right side of the purification box 34 and is connected to the output end of the hot air blower 32.

[0036] Therefore, during the waste paper pulp preparation process, the hot air blower 32 introduces hot air into the waste paper pulp through the air inlet pipe 31, thereby heating the waste paper pulp, promoting the swelling and dissociation of waste paper fibers, and reducing the pulp viscosity. After the hot air exchange with the waste paper pulp, it enters the top layer of the inner cavity of the pulping cylinder 11 from inside the waste paper pulp, and then enters the purification box 34 through the exhaust pipe 33. The activated carbon filter inside the purification box 34 absorbs the water vapor in the exhaust gas. Then the exhaust gas is returned to the hot air blower 32 through the circulation pipe 35 and reheated, and then input into the waste paper pulp again through the air inlet pipe 31. Compared with the prior art, this utility model can recover the exhaust gas after heat exchange, thereby avoiding the situation where it is directly input into the working environment and causes the working environment to heat up. It is more convenient to use and can also realize the recovery of waste heat from the exhaust gas, thereby avoiding energy waste.

[0037] It should be noted that the purification box 34 consists of a box body and a lid that is movably connected to the top of the box body. Both the box body and the lid are equipped with a latch. The purification box 34 is existing technology, so it will not be described in detail here.

[0038] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0039] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
