Description
Technical Field
[0001] The utility model belongs to the technical field of coal tar processing, and specifically relates to a solid melting and dust removal device for coal tar pitch. Background Art
[0002] After a series of processing treatments, coal tar will generate liquid coal tar pitch. As an important by-product of coal, liquid coal tar pitch has a wide range of applications in fields such as building materials, waterproof materials, coatings, and chemical raw materials. At the production site, liquid coal tar pitch will be loaded into tank trucks for transportation and sales. When there is too much remaining coal tar pitch, in order to prevent accumulation and facilitate storage, the liquid coal tar pitch will be cooled down to become solid coal tar pitch for storage. When customers need liquid coal tar pitch later, it will be melted and then sold again. In the existing melting devices, when solid coal tar pitch is conveyed into the device and passes through the crushing device, it is easy to generate dust particles, which not only cause harm to the human body but also pollute the environment. Moreover, the existing melting devices have low melting efficiency and uneven heating, resulting in a large amount of solid particles when melted into a liquid, and the product quality is low. Therefore, it is necessary to design a device that can evenly heat and melt solid coal tar pitch and can perform dust treatment. Summary of the Utility Model

In order to make the interior of the melting tank 1 heat evenly and improve production efficiency, a heating pipe 2 is fixedly connected to the outside of the melting tank 1. The heating pipe 2 is set as a semi-circular pipe, and the side with a larger area is fixedly connected to the outer wall of the melting tank 1. In order to maximize the heat efficiency of the heating pipe 2 and keep the temperature inside the melting tank 1 stable, a heat insulation layer 3 is wrapped around the outside of the heating pipe 2. In order to accelerate the melting speed of solid coal tar pitch, a first motor 5 is fixedly connected to the top of the melting tank 1. The output end of the first motor 5 is fixedly connected to a coupling 6. The coupling 6 passes through the top wall of the melting tank 1 and is fixedly connected to a stirring shaft 7. In order to facilitate the entry of solid coal tar pitch into the tank interior, a feeding port 4 is opened on one side of the top of the melting tank 1. The width of the feeding port is set to allow large pieces of solid coal tar pitch to pass through. In order to reduce the pressure inside the melting tank 1 during the heating process, an air outlet pipe 14 is fixedly connected to the other side of the top of the melting tank 1. In order to ensure that the gas inside the melting tank 1 enters the filtration box 13 through the air outlet pipe 14, an induced draft fan 21 is installed on the air outlet pipe 14. In order to filter the gas discharged from the melting tank 1 and prevent air pollution, the other end of the air outlet pipe 14 passes through the top wall of the filtration box 13 and extends to the inner bottom. In order to input liquid coal tar pitch and separate it from the solid coal tar pitch input port, a feeding pipe 16 is fixedly connected to one side of the melting tank 1 through the heat insulation layer 3. In order to facilitate the collection of the melted liquid coal tar pitch, a discharge port 12 is opened at the bottom of the melting tank 1, and a valve is provided at the discharge port 12 to facilitate the control of the outflow of the liquid coal tar pitch. A screw conveyor 9 is fixedly connected below the discharge port 12. The screw conveyor 9 is controlled by a second motor 10. In order to discharge the filtered gas, an air outlet hole 18 is opened at the top of the filtration box 13.
[0017] In order to improve the stirring effect, spiral stirring blades 8 are provided on the stirring shaft 7. At the same time, setting the spiral stirring blades 8 can reduce the friction with the coal tar pitch and improve the service life of the device.
[0018] In order to filter out large particle solid impurities in the melting tank 1 and prevent blockage of the air outlet pipe 14, a filter screen 15 is fixedly connected to the air inlet end of the air outlet pipe 14. At the same time, the filter screen 15 can play a role in preliminary filtration.

[0021] The specific working process of the present utility model is as follows:
[0022] When it is necessary to melt solid coal pitch, first, part of the liquid coal pitch is conveyed into the melting tank 1 through the feeding pipe 16. At the same time, the heating pipe 2 is turned on to raise the temperature inside the melting tank 1, and the temperature detected by the temperature detector 20 is observed at all times. After the temperature inside the melting tank 1 has risen for a period of time, the solid coal pitch is sent into the melting tank 1 through the feeding port 4 by the lifting frame, and the first motor 5 is controlled to start rotating, driving the stirring shaft 7 and the spiral stirring blade 8 to start rotating. Then, the induced draft fan 20 is turned on to extract the gas inside the melting tank 1, accelerating the melting speed of the coal pitch. During the heating and stirring process, the generated gas and dust particles are conveyed through the air outlet pipe 14 into the water inside the right filter box 13. Through the filtration of water and the filtration layer in the middle of the filter box 13, the fine dust particles carried out in the air outlet pipe 14 can be precipitated to the bottom of the filter box 13, so that the purified air is discharged from the air outlet hole 18 at the top of the filter box 13. After melting into a complete liquid, the valve below the melting tank 1 is opened to allow the coal pitch to flow into the lower auger conveyor 9, and the second motor 10 is turned on for conveying. Melting the solid coal pitch according to the above steps can improve the melting efficiency, filter out the gas and dust particles generated in the device, protect the health of the staff, and protect the environment.
