Description

Technical Field

[0001] The utility model relates to the technical field of heating devices, in particular to a standby heating device for disperse dye intermediates. Background Art

[0002] Dye intermediates refer to various aromatic hydrocarbon derivatives used in the production of dyes and organic pigments. They are made from aromatic hydrocarbons such as benzene, toluene, naphthalene and anthracene from coal chemical industry and petrochemical industry through a series of organic synthesis unit processes. Dye intermediates have developed into important basic organic intermediates due to their wide applications and large usage. In the preparation process of disperse dye intermediates, the raw materials for the preparation of disperse dye intermediates need to be heated and reacted, so a heating device is required.

[0003] A Chinese utility model patent with publication number CN214486825U discloses a standby heating device for disperse dye intermediate system, including a device shell, a heating barrel, a heating tube, a stirring paddle and a rubber scraper, a heating barrel is fixed inside the device shell, a rotating rod is rotatably installed inside the heating barrel, and an insulation sleeve is set on the outer wall of the device shell, stirring blades are welded on the outer walls of the top and bottom of the rotating rod, a discharge pipe is fixed on both sides of the bottom end of the heating barrel, the bottom end of the discharge pipe extends to the bottom of the device shell, and a solenoid valve is installed inside the discharge pipe, a feed port is set on both sides of the top end of the heating barrel, and a support block is fixed on the inner wall of the feed port. The utility model not only improves the uniformity of the intermediate heating, improves the stirring effect, and reduces the intermediate adhering to the inner wall of the heating barrel, but also facilitates the filtering and refinement of the added intermediate.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: the above-mentioned device adds the intermediate raw material into the heating barrel by pouring the intermediate into the feed port, and filters the intermediate through the screen set in the feed port. In actual operation, when the staff pours too fast, the speed at which the intermediate passes through the screen tends to gradually slow down and accumulate on the screen. At this time, the staff needs to manually shake the screen to restore the speed at which the intermediate passes through the screen, which is inefficient. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a standby heating device for disperse dye intermediate production.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a standby heating device for disperse dye intermediate system, including a device shell and a heating barrel arranged in the device shell, the upper surface of the heating barrel is provided with a feed port, the upper surface of the feed port is provided with two slide grooves, both of the two slide grooves are slidably provided with slide rods, a filter screen is jointly installed on the two slide rods, and the filter screen is provided with an auxiliary component for accelerating the filtering efficiency of the filter screen.

[0007] By adopting the above technical solution, when the staff needs to produce dye intermediates, the staff needs to put the intermediate raw materials into the feed port, and the filter screen can filter the intermediate raw materials. Afterwards, the staff only needs to start the auxiliary component to rotate the stirring rod, and then the stirring rod drives the intermediate raw materials accumulated on the filter screen, thereby accelerating the speed of the intermediate raw materials isomorphic to the filter screen, and the staff does not need to actively stir the intermediate raw materials, thereby reducing the difficulty of operation for the staff. Furthermore, the staff only needs to start the heating device in the device shell to increase the temperature of the heating barrel, and then the heating barrel heats the intermediate raw materials.

[0008] Furthermore, the auxiliary component includes a connecting rod installed together on two sliding rods, a driving motor fixed to the bottom surface of the connecting rod, and a stirring rod fixed to the end of the output shaft of the driving motor. The output shaft of the driving motor passes through the filter screen and is rotatably connected.

[0009] By adopting the above technical solution, when the staff needs to put the intermediate raw material into the feed port, the staff needs to start the drive motor to rotate the output shaft of the drive motor, and then the stirring rod follows the output shaft of the drive motor to rotate, so that the stirring rod stirs the intermediate raw material accumulated on the filter screen, thereby speeding up the rate at which the intermediate raw material passes through the filter screen, thereby shortening the time required for the staff to add the intermediate raw material.

[0010] Furthermore, scrapers are provided on two opposite side walls of the stirring rod, and the bottom surface of the scraper is flush with the bottom surface of the filter screen.

[0011] Furthermore, the scraper is made of silicone.

[0012] By adopting the above technical solution, when the stirring rod rotates, the scraper rotates with the stirring rod, thereby reducing the probability of part of the intermediate raw material entering between the stirring rod and the filter screen, thereby reducing the probability of the stirring rod getting stuck.

[0013] Furthermore, a limiting groove is provided on the side wall of the slide rod, a limiting block is slidably arranged in the limiting groove, a limiting spring is fixed on the side wall of the limiting block, the other end of the limiting spring is fixed on the inner wall of the limiting groove, and a connecting rope is arranged on the side wall of the limiting block close to the limiting spring.

[0014] Furthermore, the inner wall of the slide groove is provided with limiting holes with limiting blocks matching each other.

[0015] By adopting the above technical solution, when the staff installs the filter, they need to manually move the limit block completely into the limit slot and connect the slide bar with the slide slot, so that the filter can move downward with the slide bar. Then, when the limit slot is directly opposite to the limit hole, the limit block is connected with the limit hole under the action of the limit spring, so that the slide bar can remain stable under the action of the limit block.

[0016] Furthermore, a driving rod is slidably provided on the upper surface of the sliding rod, and a side wall of the driving rod is fixed to an end of the connecting rope away from the limiting block.

[0017] By adopting the above technical solution, when the staff needs to clean the filter, the staff only needs to press the driving rod to make one end of the connecting rope move downward along with the driving rod, thereby making the end of the connecting rope connected to the limit block move away from the limit hole, so that the limit block is separated from the limit hole under the action of the connecting rope. Furthermore, the staff only needs to pull the sliding rod upward to separate the filter from the feed port.

[0018] Furthermore, a control switch is provided on the upper surface of the sliding rod, and the control switch is electrically connected to the driving motor.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In this application, when the staff needs to produce dye intermediates, the staff needs to put the intermediate raw materials into the feed port, so that the filter can filter the intermediate raw materials. Afterwards, the staff only needs to start the auxiliary component to rotate the stirring rod, and then the stirring rod drives the intermediate raw materials accumulated on the filter, thereby speeding up the speed of the intermediate raw materials isomorphic to the filter, and the staff does not need to actively stir the intermediate raw materials, thereby reducing the difficulty of operation for the staff. Furthermore, the staff only needs to start the heating device in the device shell to increase the temperature of the heating barrel, so that the heating barrel heats the intermediate raw materials;

[0021] 2. In the present application, when the staff needs to put the intermediate raw material into the feed port, the staff needs to start the drive motor, so that the output shaft of the drive motor can rotate, and then the stirring rod can rotate along with the output shaft of the drive motor, so that the stirring rod can stir the intermediate raw material accumulated on the filter screen, thereby speeding up the rate at which the intermediate raw material passes through the filter screen, thereby shortening the time required for the staff to add the intermediate raw material;

[0022] 3. In this application, when the staff installs the filter, they need to manually move the limit block completely into the limit slot and connect the slide bar with the slide slot, so that the filter can move downward with the slide bar. Then, when the limit slot is directly opposite to the limit hole, the limit block is connected with the limit hole under the action of the limit spring, so that the slide bar can remain stable under the action of the limit block.

The heating barrel 11 is arranged in the device housing 1, and the feed port 2 is arranged on the upper surface of the heating barrel 11. Two slide grooves 21 are provided on the upper surface of the feed port 2, and the slide bar 3 is a rectangular rod-shaped structure. The slide bar 3 is provided with two and is slidably arranged in the two slide grooves 21 respectively.

[0032] When the staff needs to put the intermediate raw materials into the feed port 2, the staff needs to start the drive motor 42, so that the output shaft of the drive motor 42 can rotate, and then the stirring rod 43 can rotate along with the output shaft of the drive motor 42, so that the stirring rod 43 can stir the intermediate raw materials accumulated on the filter screen 31, thereby speeding up the rate at which the intermediate raw materials pass through the filter screen 31, thereby shortening the time required for the staff to add the intermediate raw materials.

Furthermore, the staff only needs to start the heating device in the device housing 1 to increase the temperature of the heating barrel 11, and then the heating barrel 11 heats the intermediate raw materials.
