Description

Technical Field

[0001] The utility model relates to the technical field of coal tar purification, in particular to a coal tar purification pretreatment device. Background Art

[0002] Coal tar is a black or dark brown viscous liquid with a pungent odor generated during the dry distillation of coal. Coal tar can be divided into low-temperature coal tar, medium-temperature coal tar and high-temperature coal tar according to the dry distillation temperature. The coal tar obtained in coke production belongs to high-temperature coal tar. It is one of the coke oven gas purification products condensed and separated during the cooling process of raw coal gas.

[0003] For example, the patent document with the announcement number CN 217663267 U discloses a coal tar purification pretreatment device, including a pretreatment box, the top of which is fixedly connected to a cylinder, and the output end of the cylinder is fixedly connected to a connecting tube, the interior of the connecting tube near the bottom is fixedly connected to an air guide hood, the outer side of the air guide hood is provided with an air guide hole in an annular shape, the bottom of the connecting tube is fixedly connected to a hollow air guide plate, and the air guide hood is located inside the hollow air guide plate, the bottom of the hollow air guide plate is provided with connecting holes at equal distances, and the inner wall of each connecting hole is fixedly connected to an air guide pipe. The utility model is provided with a No. 1 hydraulic cylinder, a lifting frame and a scraper. After the coal tar raw material contacts and reacts with the pretreatment gas, when the material is unloaded, the No. 1 hydraulic cylinder is adjusted to drive the scraper under the lifting frame to scrape off the coal tar raw material attached to the inner wall of the pretreatment box, thereby reducing the loss of the coal tar raw material.

[0004] However, during actual use, this structure can only perform purification pretreatment operations when the coal tar is in a static state, resulting in the inability to more fully mix and react the coal tar with the pretreatment gas. The overall pretreatment time is relatively long. At the same time, the equipment cannot recycle the gas that has been treated once, and cannot achieve more sufficient purification pretreatment operations for the coal tar, and cannot meet daily use needs. Therefore, it is urgent to design a coal tar purification pretreatment device to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a coal tar purification pretreatment device to solve the problem that the existing structure proposed in the above background technology can only perform purification pretreatment operations when the coal tar is in a static state during actual use, resulting in the coal tar being unable to undergo a more sufficient mixing reaction operation with the pretreatment gas, and the overall pretreatment time is relatively long. At the same time, the equipment is unable to recycle the gas that has been treated once, and is unable to achieve a more sufficient purification pretreatment operation for the coal tar, and is unable to meet daily use needs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a coal tar purification pretreatment device, comprising a support base, a first gas delivery valve is arranged on one side of the interior of the support base, a second gas delivery valve is arranged on the other side of the interior of the support base, a driving motor is arranged at the bottom of the second gas delivery valve, and one end of the driving motor is fixedly connected to a feeding screw rod;

[0008] Preferably, a top cover is fixedly connected to the top of the recovery bottle, and an air control pump is provided on the top of the top cover.

[0009] Preferably, a material collecting seat is provided at the top end of the oil storage tank, and a material distributing seat is provided at the bottom end of the oil storage tank.

[0010] Preferably, a conveying frame is fixedly connected to the four sides of the oil storage tank, and a material conveying trough is arranged inside the conveying frame.

[0011] Preferably, an air control pipe is fixedly connected to the side of the material collecting seat, and an air supply pipe is fixedly connected to the side of the material distributing seat.

[0012] Preferably, an air inlet seat is fixedly connected to the side surface of one end of the support base, and a feed seat is fixedly connected to the side surface of the other end of the support base.

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

[0014] The coal tar purification and pretreatment device, through the arranged supporting base, the first gas delivery valve, the second gas delivery valve, the driving motor, the feeding screw rod, the new gas cylinder, the oil storage tank, the material collecting seat, the material distribution seat, the conveying rack, the feeding trough and the gas delivery pipe, can enable the equipment to perform more efficient coal tar purification and pretreatment operations. In actual use, the staff first injects the coal tar to be treated into the interior of the oil storage tank, and stores the gas used for pretreatment into the interior of the new gas cylinder, and then continuously passes the gas into the interior of the material distribution seat through the gas delivery pipe, and then starts the driving motor to drive the feeding screw rod to continuously convey the coal tar downward at the bottom of the oil storage tank, and the coal tar flows upward along the material distribution seat to the internal feeding trough of the conveying rack on the side of the oil storage tank, and finally the coal tar and the gas enter the material collecting seat at the top of the oil storage tank together, and the coal tar returns to the interior of the oil storage tank again for a cyclic reaction operation, so that the coal tar can be in a flowing state. More efficient pretreatment reaction operations are performed, which reflects the practicality of the equipment design.

[0015] The coal tar purification pretreatment device further improves the overall use of the equipment through the support base, new gas cylinder, oil storage tank, recovery bottle, top cover, air control pump, material collection seat, material distribution seat and gas transmission pipe. In daily use, when coal tar and pretreatment reaction gas enter the material collection seat together, the air control pump on the top of the top cover can be started to suck out the pretreated gas flow in the material collection seat through the air control pipe, and then the gas is temporarily stored in the recovery bottle. After that, when the coal tar is circulated once inside the oil storage tank through the driving motor and the feeding screw rod, the pretreated gas flow in the recovery bottle can be introduced into the interior of the material collection seat through the air control pump and the air control pipe for secondary mixing with the coal tar, so that the coal tar can fully absorb the components in the gas, thereby improving the utilization rate of raw materials and reflecting the comprehensiveness of the equipment design.
