Description

Technical Field

[0001] The utility model relates to the field of coal tar, in particular to a flushing oil tank for coal tar processing. Background Art

[0002] Coal tar is a product of the crude gas generated by the pyrolysis of coal in the coking industry, accounting for approximately 3%-4% of the coal charged to the furnace. Its composition is extremely complex, and in most cases, it is separated and purified by the coal tar industry before being utilized. At room temperature and pressure, the product is a black, viscous liquid. Further processing of the fractions can yield a variety of products, such as mothballs, asphalt, plastics, and pesticides. However, existing coal tar processing results in high levels of oil residue in the oil tank, which can easily cause blockage and is in urgent need of improvement. Utility Model Content

[0003] The utility model aims to provide a flushing oil tank for coal tar processing, which is used to solve the problem that the existing flushing oil tank for coal tar processing is easily blocked.

[0004] In order to solve the above problems, the utility model provides a flushing oil tank for coal tar processing, comprising an outer barrel body and an inner barrel body, the inner barrel body and the outer barrel body are coaxially and detachably arranged, a first oil outlet pipe is provided below the side wall of the outer barrel body, a second oil outlet pipe is provided above the first oil outlet pipe, a guide pipe is obliquely provided between the first oil outlet pipe and the second oil outlet pipe, a first filter hole is provided below the side wall of the inner barrel body, a liquid baffle is fixedly provided coaxially with the outer wall of the inner barrel body, a plurality of second filter holes are provided on the liquid baffle, a first flow valve is installed on the first oil outlet pipe, and a second flow valve is installed on the second oil outlet pipe.

[0005] The utility model provides a coal tar processing flushing oil tank which also has the following technical features:

[0006] Furthermore, the distance between the inner wall of the outer barrel body and the outer wall of the inner barrel body is 3-5 cm.

[0007] Furthermore, a support ring is fixedly provided on the top of the inner barrel body, and the bottom wall of the support ring is in contact with the top wall of the outer barrel body.

[0008] Furthermore, the aperture of the first filter hole is 1-2 mm, and the aperture of the second filter hole is 0.5-1 mm.

[0009] Furthermore, the outer barrel and the inner barrel are both made of stainless steel.

[0010] Furthermore, a handle is fixedly provided on the top of the support ring.

[0011] The utility model has the following beneficial effects: under normal conditions, the second oil outlet pipe is in a closed state; when the oil discharged from the first oil outlet pipe contains a lot of oil residue, the first flow valve is closed, and the oil in the outer barrel cannot be directly discharged from the first oil outlet pipe. The second flow valve is opened, and the coal tar passes through the first filter hole and the second filter hole for double filtration and then passes through the guide pipe before being discharged from the first oil outlet pipe, effectively avoiding the occurrence of pipeline blockage.

[0014] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

[0015] like Figures 1 to 2 In the embodiment of the flushing oil tank for coal tar processing of the utility model shown in the figure, the outer barrel body 1 and the inner barrel body 2 are provided. The inner barrel body 2 and the outer barrel body 1 are coaxially detachable. A first oil outlet pipe 11 is provided below the side wall of the outer barrel body 1. A second oil outlet pipe 12 is provided above the first oil outlet pipe 11. A guide pipe 13 is provided obliquely between the first oil outlet pipe 11 and the second oil outlet pipe 12. A first filter hole 21 is provided below the side wall of the inner barrel body 2. A liquid baffle plate 3 is fixedly provided coaxially on the outer wall of the inner barrel body 2. A plurality of second filter holes 31 are provided on the liquid baffle plate 3. A first flow valve 4 is installed on the first oil outlet pipe 11, and a second flow valve 5 is installed on the second oil outlet pipe 12. Specifically, under normal conditions, the second oil outlet pipe 12 is in a closed state; when the oil discharged from the first oil outlet pipe 11 contains a lot of oil residue, the first flow valve 4 is closed, and the oil in the outer barrel 1 cannot be discharged directly from the first oil outlet pipe 11. The second flow valve 5 is opened, and the coal tar is double-filtered through the first filter hole 21 and the second filter hole 31 and then discharged from the first oil outlet pipe 11 through the guide pipe 13, effectively avoiding pipeline blockage.
