Description

Technical Field

[0001] This utility model relates to a pyrolysis heating tube, belonging to the field of pyrolysis furnace technology. Background Technology

[0002] The heating tube in the pyrolysis device for inferior waste plastics is one of the core components of the system. Its main function is to provide the necessary heat to the waste plastics during the pyrolysis process so as to achieve their chemical decomposition at high temperature.

[0003] Conventional heating tubes are made of cast iron. After long-term repeated heating, the inner wall of the heating tube is prone to aging, causing the surface metal layer to detach and forming debris. Excessive accumulation of debris inside the tube affects the heating uniformity of the heating tube, resulting in uneven heating and incomplete plastic pyrolysis. Therefore, people need to regularly clean the inner wall of the heating tube with a wire brush. After cleaning, the heating tube should be turned over and the debris inside should be poured out.

[0004] The above-mentioned process of emptying debris has the following disadvantages: the heating tube is heavy and it is very inconvenient to manually turn it over. At the same time, due to the curved shape of the heating tube, the debris cannot be poured out directly. Instead, it is necessary to adjust the angle and shake and swing the heating tube multiple times before it can be poured out. The process is time-consuming and laborious. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a pyrolysis heating tube that facilitates the centralized cleaning of debris inside the heating tube, improves the efficiency of cleaning debris from the heating tube, and reduces the labor intensity of manually cleaning debris from the heating tube.

[0006] The present invention provides a pyrolysis heating tube, comprising: a hollow partition plate disposed inside the heating tube body, the partition plate dividing the internal space of the heating tube body into several heating chambers.

[0007] The partition includes: a main body, with an intermediate plate inside the main body, which divides the interior of the main body into several cleaning chambers.

[0008] The cleaning chamber is equipped with several partitions; the cleaning chamber is divided into a chip removal chamber and an air intake chamber by the partitions.

[0009] The separator has an air inlet hole, and the chip removal chamber and the air inlet chamber are connected through the air inlet hole.

[0010] The main body has a chip inlet hole on its side, and the heating chamber and the chip removal chamber are connected through the chip inlet hole.

[0011] Furthermore, the top of the chip removal chamber is provided with an outlet, and the outlet is equipped with a chip removal interface; the chip removal interface can be connected to the air intake of the vacuum cleaner through a pipeline.

[0012] Furthermore, the chip inlet is located on one side of the bottom of the main body.

[0013] The chip removal chamber is designed to taper from the chip inlet side to the chip removal interface side.

[0014] Furthermore, an air inlet is provided at the top of the air intake chamber, which can be connected to the atmosphere.

[0015] Furthermore, the outer wall of the heating tube body is uniformly covered with an amorphous nano-ceramic coating.

[0016] Furthermore, a sealing cap is also provided on the main body of the heating element.

[0017] The sealing cap can be fitted onto the opening of the heating chamber.

[0018] The advantages of this utility model compared with the prior art are:

[0019] The dust removal chamber inside the partition is connected to a vacuum cleaner and an air intake chamber for use. This allows for the rapid removal of debris from multiple heating chambers within the heating tube, eliminating the need for manual rotation of the heating tube and significantly improving the efficiency and convenience of cleaning debris.

[0028] 3. Sealing cap. Detailed Implementation

[0029] like Figures 1-5 As shown, this embodiment is achieved through the following technical solution: a hollow partition 2 is provided inside the heating tube body 1, which divides the internal space of the heating tube body 1 into several heating chambers 101. Heating wires can be installed inside the heating chambers 101.

[0030] The partition 2 includes: a main body 201, and an intermediate plate 202 is provided inside the main body 201, which divides the interior of the main body 201 into several cleaning chambers.

[0031] The number of cleaning chambers and heating chambers 101 are equal. In this embodiment, there are two cleaning chambers and two heating chambers 101.

[0032] The cleaning chamber is equipped with several partition strips 203; the cleaning chamber is divided into a chip removal chamber 204 and an air intake chamber 205 by the partition strips 203.

[0033] The separator 203 is provided with an air inlet 208, and the chip removal chamber 204 and the air inlet chamber 205 are connected through the air inlet 208;

[0034] The main body 201 has a chip inlet hole 207 on its side, and the heating chamber 101 and the chip discharge chamber 204 are connected through the chip inlet hole 207.

[0035] Specifically, the top of the chip removal chamber 204 is provided with an outlet, and a chip removal interface 206 is provided on the outlet; the chip removal interface 206 can be connected to the air intake of the vacuum cleaner through a pipe.

[0036] Specifically, the chip inlet 207 is located on one side of the bottom of the main body 201, such as... Figure 1 , Figure 2 As shown.

[0037] The chip removal chamber 204 is tapered from the chip inlet hole 207 to the chip removal interface 206.

[0038] Specifically, an air inlet 2051 is provided at the top of the air intake chamber 205, and the air inlet 2051 can communicate with the atmosphere.

[0039] Specifically, the outer wall of the heating tube body 1 is uniformly covered with an amorphous nano-ceramic coating. The amorphous nano-ceramic coating is applied to the outer surface of the heating tube body 1 to solve the problem of coking on the surface of the heating tube after the waste plastic is heated.

[0040] Amorphous nano-ceramic materials are a type of coating material that has been successfully applied; they are non-toxic and non-volatile. After curing, the coating forms a highly dense protective film on the surface of the heating tube, which is tightly bonded to the outer wall of the heating tube. The surface of this coating is smooth, which can effectively reduce the problem of coking accumulation.

[0041] Specifically, a sealing cap 3 is also provided on the heating tube body 1; the sealing cap 3 can be fitted onto the opening of the heating chamber 101. Normally, the sealing cap 3 does not participate in the working process of the heating tube. It is only when cleaning debris inside the heating tube body 1 that the sealing cap 3 is engaged with the opening of the heating chamber 101. Its purpose is to seal the heating chamber 101, ensure that the airflow enters the chip removal chamber 204 from the air inlet chamber 205, increase the vacuum degree of the chip removal chamber 204 and the air inlet chamber 205, and improve the chip removal efficiency.

[0042] The specific working principle of this utility model is as follows:

[0043] When the heating tube is working, the material inside the heating chamber 101 ages and peels off due to temperature changes; the peeled debris accumulates at the bottom of the heating tube body 1; when cleaning the debris, the heating tube body 1 needs to be tilted slightly by hand so that the debris at the bottom moves towards the side where the partition 2 is located.

[0044] The vacuum cleaner is connected to the chip removal interface 206. The air intake chamber 205 draws in fresh air through the air intake port 2051 at the top. The air flows into the chip removal chamber 204 through the air intake hole 208 on the partition bar. Under the action of the negative pressure of the airflow, the debris enters the chip removal chamber 204 through the chip inlet hole 207 and is finally discharged into the vacuum cleaner from the chip removal interface 206. Thus, the debris in the heating tube body 1 is discharged.

[0045] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
