Technical Field

[0001] This application relates to the field of coal pitch technology, and in particular to a coal pitch coking cleaning device. Background Technology

[0002] During the upgrading and modification processes of coal tar pitch, coking occurs as a result. This coking is highly adhesive and adheres to the side walls of the reaction tower. Workers need to regularly clean this coking to maintain the normal operation of the production unit. Currently, the cleaning of this coking is mostly done manually, which is slow, labor-intensive, and the coking contains toxic and harmful substances; prolonged exposure inside the reaction tower can pose health risks.

[0015] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0016] Please refer to Figures 1 to 3 The coal tar pitch coking cleaning device includes: Casing 1; Heater 2 fixed on housing 1; The removal mechanism 3 is fixed to the housing 1 and is located behind the heater 2; A brushing mechanism 4 is fixed on the housing 1 and is located behind the scraping mechanism 3; The negative pressure dust removal mechanism 5, which is connected to the housing 1, is used to absorb and clean the dust generated during the coking process.

[0017] In a preferred embodiment, the housing 1 of this application is provided with side plates on both sides, which serve to support and seal. The upper and lower ends of the housing 1 are open, with the upper end of the housing 1 facilitating the passage of coking material and the lower end of the housing 1 facilitating the outflow of coking material.

[0018] This application first heats the coking material using heater 2 to reduce its adhesion to the tower wall. This makes removing the coking material much easier. Then, the coking material on the tower wall is removed using scraping mechanism 3. For stubborn coking material, a brushing mechanism 4 is used for further cleaning. The dust generated by scraping mechanism 3 and brushing mechanism 4 is absorbed by negative pressure dust collection mechanism 5.

[0019] The heater 2 in this application is electrically heated. The power can be supplied via an external electrical wire or it can have its own built-in power source.

[0020] In a preferred embodiment, the removal mechanism 3 includes: 301, a shovel body for removing coke deposits; Vibration motor 302 is located on the shovel body 301; A support rod 303 is hinged to the shovel body 301, and the other end of the support rod 303 is connected to the housing 1; A buffer 304 is connected to the shovel body 301, and the other end of the buffer 304 is connected to the housing 1.

[0021] The shape of the shovel body 301 in this application is determined according to the shape of the cleaning surface. If the cleaning surface is flat, then the end of the shovel body 301 is also flat. If the cleaning surface is arc-shaped, then the end of the shovel body 301 is the corresponding arc-shaped.

[0022] The vibratory motor 302 on the shovel body 301 can transmit high-frequency vibrations to the tower wall, thereby reducing the binding force between the coking material and the tower wall, making removal easier. Furthermore, the vibratory motor 302 drives the shovel body 301 to vibrate, increasing the friction between the shovel body 301 and the tower wall or coking material, and the increased temperature of the shovel body 301 makes it easier to remove coking. In addition, the reciprocating motion of the shovel body 301, inserted into the interface between the coking material and the tower wall or within the coking material, makes it easier to peel off the coking material.

[0023] The space between the support rod 303 and the shovel body 301 forms a channel for the coking material to fall, preventing the coking material from accumulating.

[0024] The buffer 304 can reduce the transmission of vibration from the shovel body 301 to the housing 1, making it more comfortable for people to grip and operate, and also making it less likely for bolts and other connection points to fall off or break.

[0025] In a preferred embodiment, the vibratory motor 302 is located at the front end of the shovel body 301, the support rod 303 is located at the middle end of the shovel body 301, and the buffer 304 is located at the rear end of the shovel body 301. In this way, the hinge point of the vibratory motor 302, the support rod 303, and the buffer 304 form a lever, and the buffer 304 has a better force-dissipating effect.

[0026] The buffer element 304 can be a damping block, rubber block, or other component with a buffering function. In a preferred embodiment, the buffer element 304 is a spring. In a preferred embodiment, the housing 1 and the shovel body 301 are provided with lugs, and the two ends of the spring are provided with hooks.

[0027] The brushing mechanism 4 of this application can reciprocate to remove coking material, or it can rotate to remove coking material. In a preferred embodiment, when using a rotating brush to remove coking material, the brushing mechanism 4 includes: Brush body 401 for removing coke deposits; The rotating shaft 402 is connected to the brush body 401; A drive motor 403 is connected to the other end of the rotating shaft 402 and is fixed on the housing 1.

[0028] In a preferred embodiment, the brush body 401 can be a wire brush or a grinding disc, which removes the coking material through friction.

[0029] In a preferred embodiment, the brush body 401 can be a single unit or an array, i.e., brushing in a multi-row, multi-column format.

[0030] In a preferred embodiment, the brush body 401 can also be a roller brush, that is, the arc surface of the brush body 401 contacts the tower wall.

[0031] In a preferred embodiment, the negative pressure dust removal mechanism 5 includes: The negative pressure pipe 501 is connected to the housing 1; Cyclone dust collector 502 is connected to the other end of negative pressure pipe 501; A negative pressure fan 503 is connected to the top of the cyclone dust collector 502; The return pipe 504 is connected to the negative pressure fan 503, and the other end of the return pipe 504 is connected to the heater 2.

[0032] The dust is separated from the hot air by the cyclone dust collector 502. The hot air is then reheated through the return pipe 504 and blown onto the coking material. In this way, heat and airflow can be effectively utilized, and the airflow can heat the coking material more quickly.

[0033] Since the coal tar pitch coking cleaning device is mobile during operation, in a preferred embodiment, the negative pressure pipeline 501 includes a connecting hose and a straight rigid pipe. One end of the connecting hose is connected to the housing 1, and the other end of the connecting hose is connected to the straight rigid pipe. The other end of the straight rigid pipe is connected to the air inlet of the cyclone dust collector 502.

[0034] In a preferred embodiment, an adapter is provided between the connecting hose and the straight rigid pipe.

[0035] In a preferred embodiment, the connecting hose is a corrugated hose.

[0036] The structure of the return pipe is the same as that of the negative pressure pipe, so it will not be repeated.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
