Description

Technical Field

[0001] This utility model relates to the field of pulping machine technology, specifically to an anti-clogging device for a paper pulping machine. Background Technology

[0002] A pulper is a mechanical device that converts materials such as paper, plastic, and cloth into pulp. The main components of a pulper include an input device, a mixing device, a grinding device, a filtering device, and an output device. Among them, a paper-based pulper is used to convert paper into pulp.

[0003] Existing paper pulping machines require water to be added during the process of converting paper into pulp. They are usually connected to tap water pipes and supplied with water through the municipal water network. However, when the water supply is interrupted or there is no tap water network nearby, existing paper pulping machines cannot effectively convert paper.

[0004] During the pulping process of the pulping machine, due to the certain mixing concentration of the pulp, the pulp is prone to blockage at the outlet under its own gravity, thus affecting the pulping effect and efficiency of the pulping machine.

[0005] Chinese patent application No. 202321179805.8 discloses a paper pulping machine, including a pulping machine body. The pulping machine body includes a shell, and a paper shredder and a pulping tank are provided inside the shell. The paper shredder is located at the top of the pulping tank. A dewatering mechanism is provided at the bottom of the shell. A paper inlet is provided at the top of the shell. A sensor is provided in the middle of the paper inlet. A control panel is fixedly installed on one side of the shell. The control panel is electrically connected to the sensor, the paper shredder, the pulping tank, and the dewatering mechanism.

[0006] The aforementioned pulping machine guides and limits the paper to be shredded using an anti-clogging comb. However, the pulping machine is not designed to clear the pulp. When the pulp becomes clogged in the outlet channel, the entire pulping machine needs to be partially dismantled to clear the outlet channel. This process is time-consuming and labor-intensive, and it also affects the pulping efficiency of the machine. Utility Model Content

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] like Figures 1-4 As shown, an anti-clogging device for a paper pulping machine includes a frame 1 and a barrel assembly 2 mounted on the frame 1. The frame 1 is provided with a filter assembly 3 that communicates with the top of the barrel assembly 2. A partition 4 for separating the filter assembly 3 and the barrel assembly 2 is installed on the frame 1. A support frame for supporting the barrel assembly 2 and an air jet assembly 5 located at the top of the barrel assembly 2 are installed on the partition 4. The barrel assembly 2 includes a barrel body 21 and a feed pipe 22 communicating with the top of the barrel body 21. The feed pipe 22 is arranged along the spiral direction of the barrel body 21, and an air hole 23 corresponding to the air jet assembly 5 is formed in the middle of the feed pipe 22.

[0026] The barrel assembly 2 is connected to the outside of the frame 1. The barrel assembly 2 is used to receive the slurry delivered from the outside and filter the gas in the slurry under the action of the filter assembly 3. The filter assembly 3 is a cavity structure with only a top opening under the action of the partition plate 4, and at the same time, the partition plate 4 supports the barrel assembly 2.

[0027] The jetting assembly 5 is located at the top of the barrel assembly 2, and the jetting assembly 5 jets air onto the barrel assembly 2 from top to bottom. Under the action of jetting, the slurry at the bottom of the barrel assembly 2 is prevented from clogging. At the same time, the feed pipe 22 is arranged along the spiral direction of the barrel body 21, so that the slurry enters along the spiral trajectory of the barrel body 21, thereby ensuring uniform feeding of the slurry in the barrel body 21 and preventing clogging of the barrel body 21 during the feeding process. Therefore, the feed pipe 22 and the jetting assembly 5 arranged along the spiral direction of the barrel body 21 are used to prevent clogging of the feed and discharge of the barrel body 21, respectively.

[0028] Air holes 23 are formed at the top of the feed pipe 22 and are arranged to run through the feed pipe 22 from top to bottom. The top of the feed pipe 22 is provided with an air outlet pipe 6 for connecting the feed pipe 22 and the filter assembly 3.

[0029] The air hole 23 is used to connect the jet assembly 5 with the barrel body 21, and also to connect the barrel body 21 with the outlet pipe 6. The air hole 23 satisfies the downward jet flow and also satisfies the gas discharge from the outlet pipe 6 under the suction of the filter assembly 3.

[0030] The jet assembly 5 includes a jet pump 52 and a jet pipe 51 connected to each other. The jet pipe 51 is installed on the top of the air outlet pipe 6 and is arranged along the center line of the air hole 23. The jet pipe 51 is arranged vertically from top to bottom. By installing the jet pipe 51 on the top of the air outlet pipe 6, the jet pipe 51 is positioned above the material cylinder body 21. The air hole 23 is coaxially arranged with the center line of the material cylinder body 21, thereby ensuring uniform jetting of the jet pipe 51 onto the material cylinder body 21.

[0031] The jet pump 52 is installed below the jet pipe 51 and inside the frame 1. The jet pipe 51 is equipped with a solenoid valve 53 for controlling the jet flow of the jet pipe 51. Under the action of the jet pump 52 installed below the jet pipe 51, the jet pipe 51 is ensured to be filled with jet. The solenoid valve 53 is used to control the staged jet operation of the jet pipe 51, which can realize the timed jet operation of the jet pipe 51.

[0032] The air outlet pipe 6 is set horizontally, and the bottom of the air outlet pipe 6 is sealed at the top of the feed pipe 22. The air outlet pipe 6 is used to block the air hole 23.

[0033] The bottom of the air outlet pipe 6 is provided with an air outlet hose 61 connected to the air outlet pipe 6. The air hole 23 and the air outlet hose 61 are respectively connected to the opposite ends of the air outlet pipe 6. The bottom of the partition plate 4 forms an air outlet 42 connected to the filter assembly 3, and the bottom of the partition plate 4 forms an air outlet seat 43 connected to the air outlet pipe 6.

[0034] The filter assembly 3 includes a cylindrical filter paper 31 and an air pump 32 for evacuating air from the middle of the cylindrical filter paper 31. The bottom of the filter assembly 3 has a funnel 33 that is inclined downward from the outside to the inside, and a dust collection box 34 is provided at the bottom of the funnel 33.

[0035] The number of cylindrical filter papers 31 can be selected and set according to actual needs. Under the combined action of the air pump 32 and the cylindrical filter paper 31, air is discharged through the cylindrical filter paper 31, and the dust in the air is filtered by the cylindrical filter paper 31 and falls into the funnel 33 under the action of its own gravity, where it is collected in the dust collection box 34.

[0036] An annular ring 24 is fitted onto the main body 21 of the material cylinder, and a support frame 41 for supporting the annular ring 24 is installed on the partition plate 4. The support frame 41 is used to achieve stable support for the main body 21 of the material cylinder.

[0037] In actual use, the feed pipe 22, which is set along the spiral direction of the main body 21 of the barrel, is used to uniformly feed the main body 21 of the barrel. At the same time, the jet assembly 5 is used to push the slurry downward and partially blow it apart, so that the gas in the slurry can be discharged through the air outlet pipe 6. When the slurry is blocked at the bottom of the main body 21 of the barrel, the jet assembly 5 can provide a downward thrust to the blocked slurry, thereby clearing the blockage.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0039] Although this document frequently uses reference numerals from the accompanying drawings, such as frame 1, barrel assembly 2, barrel body 21, feed pipe 22, air hole 23, annular ring 24, filter assembly 3, cylindrical filter paper 31, suction pump 32, funnel 33, dust collection box 34, partition 4, support frame 41, air outlet 42, air outlet seat 43, jet assembly 5, jet pipe 51, jet pump 52, solenoid valve 53, air outlet pipe 6, and air outlet hose 61, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
