Description

[0001] This utility model relates to the technical field of filtration, washing and drying equipment, specifically to a three-in-one stirring shaft with backflushing and heating functions for filtration, washing and drying. Technical Background

[0002] In industries such as chemical, pharmaceutical, and food processing, filtration, washing, and drying are common material handling processes, often requiring integrated filtration, washing, and drying equipment. The stirring shaft, as the core component of this equipment, directly affects the material processing effect and efficiency. Currently, the stirring shaft in integrated filtration, washing, and drying equipment has a relatively simple function, often only providing stirring. Heating and backflushing require additional equipment or devices, which not only increases the overall size and cost of the equipment but may also lead to problems such as complex operation and low material processing efficiency. For example, additional heating devices may not heat the material evenly, affecting the drying effect; additional backflushing devices may be improperly installed, failing to effectively clean the inside of the equipment or disturb the material.

[0003] Chinese patent CN119113608A discloses a cylindrical filter washing and drying machine (cylindrical three-in-one), which employs high-pressure filtration through a gas channel, high-pressure washing, high-pressure dry hot gas penetrating the material layer for drying, and screw unloading. This patent achieves purging disturbance and heating of the material inside the equipment. However, this invention requires a complete modification of the equipment, resulting in high modification costs and a complex structure. Therefore, there is an urgent need for a stirring shaft that is easy to install and integrates heating and backflushing functions to solve the problems existing in the prior art.

[0004] Currently, the chemical industry lacks a three-in-one stirring shaft that integrates heating and backflushing functions, is easy to operate, and can efficiently process materials, thereby achieving the integration of backflushing and heating functions. To address this, a three-in-one stirring shaft with backflushing and heating functions was designed, which has practical significance and good application prospects. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] The purpose of this invention is to provide a three-in-one stirring shaft with backflushing, heating and filtration functions, washing and drying, to solve the problems of existing stirring shafts having single function, large equipment size, high cost, complicated operation and low processing efficiency.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a three-in-one stirring shaft with backflushing, heating, and filtration functions, including: an air source pipe, a rotary joint, a heating pipe, a backflushing pipe, a main shaft, a guide plate, a half-pipe, nozzles, a seal, a heat medium inlet, a heat medium outlet, and a gas inlet. One end of the air source pipe is combined with the heating pipe through the rotary joint, and the other end is connected to the backflushing pipe through the seal. The seal is located between the main shaft and the guide plate. The air source pipe and the heating pipe are located inside the main shaft. The half-pipe is equipped with evenly distributed nozzles. The backflushing gas enters the half-pipe through the backflushing pipe and is then evenly sprayed out through the nozzles. The backflushing pipe is connected to the nozzles through the half-pipe.

[0009] Furthermore, a sealing element is provided between the half-pipe and the gas source pipe to ensure the sealing of the connection between the half-pipe and the gas source pipe, prevent leakage of heating medium or backflushing medium, and avoid leakage of backflushing medium at the weld joint, thereby ensuring stable backflushing pressure.

[0010] Furthermore, the guide plate can guide the heating medium to flow fully inside the main shaft, improving heating uniformity.

[0011] Furthermore, the nozzles are evenly distributed on the half-pipe, allowing the backflushing medium to act uniformly on the materials inside the equipment, thus enhancing the backflushing effect.

[0012] (3) Functional benefits

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The device integrates heating and backflushing functions, eliminating the need for separate heating and backflushing devices, thus reducing equipment size and cost. The heating medium flows through the internal channel of the main shaft, providing a large contact area with the backflushing gas, resulting in uniform heating and high drying efficiency. The backflushing medium is sprayed out through nozzles on the half-pipe, precisely targeting the materials inside the equipment for excellent cleaning and enhanced material mixing, further improving washing efficiency. This device has a compact structure, is easy to operate, and contributes to improving the overall operating efficiency of the equipment. Attached Figure Description

[0020] Please see the appendix Figure 1 A three-in-one stirring shaft with backflushing, heating, and filtration functions, comprising an air source pipe 1, a rotary joint 2, a heating pipe 3, a backflushing pipe 4, a main shaft 5, a guide plate 6, a half-pipe 7, nozzles 8, a seal 9, a heat medium inlet 10, a heat medium outlet 11, and a gas inlet 12. The gas inlet 12 is located at one end of the air source pipe 1. One end of the air source pipe 1 is combined with the heating pipe 3 through the rotary joint 2, and the other end is connected to the backflushing pipe 4 through the seal 9. The heat medium inlet 11 and the heat medium outlet 12 are located at the rotary joint 2 and connected to the heating pipe 3. The seal 9 is located between the main shaft 5 and the guide plate 6. The air source pipe 1 and the heating pipe 3 are arranged inside the main shaft 5. The half-pipe 7 is equipped with evenly distributed nozzles 8. The backflushing medium enters the half-pipe 7 through the backflushing pipe 4 and is then evenly sprayed out through the nozzles 8. The backflushing pipe 4 is connected to the nozzles 8 through the half-pipe 7.

[0021] The specific working process of this utility model is as follows:

[0022] In use, during equipment operation, the backflushing gas enters the gas source pipe 1 through the gas inlet 12 of the rotary joint, flows into the main shaft 5, enters the half-pipe 7 through the backflushing pipe 4, and finally is sprayed out through the nozzle 8 to clean the inside of the equipment or agitate the materials, thereby improving the washing effect and the flowability of the materials. At the same time, the heating medium enters the heating pipe 3 through the heat medium inlet 10 and then flows into the main shaft 5. Under the guidance of the guide plate 6, the heating medium flows fully inside the main shaft 5 and exchanges heat with the backflushing gas. The gas that has undergone heat exchange flows out from the heat medium outlet 11, thereby achieving the heating and drying of the backflushing gas.

[0023] Working principle:

[0024] During equipment operation, backflushing gas enters the gas source pipe through the gas inlet of the rotary joint, flows into the main shaft, enters the half-pipe through the backflushing pipe, and finally is sprayed out through the nozzle to clean the inside of the equipment or agitate the material, thereby improving the washing effect and the flowability of the material. At the same time, the heating medium enters the heating pipe through the heat medium inlet and then flows into the main shaft. Under the guidance of the guide plate, the heating medium flows fully inside the main shaft and exchanges heat with the backflushing gas. The gas that has undergone heat exchange flows out from the heat medium outlet, thus achieving the heating and drying of the backflushing gas.

[0025] This invention integrates backflushing and heating functions into the stirring shaft, which can evenly heat the material and effectively clean or disturb the inside of the equipment. It is simple to operate and has a low cost.

[0026] Finally, it should be noted that various modifications and variations can be made to this invention by those skilled in the art.
