Description

Technical Field

[0001] The utility model relates to the technical field of exhaust devices, in particular to an exhaust device used for chemical oil refining and coking. Background Art

[0002] The gas discharged into the coke slag pool when the coking unit of a petrochemical company releases pressure before producing coke contains a lot of waste gas components, and exhaust devices are becoming more and more popular. Traditional exhaust devices usually allow the waste gas to be treated and purified through a filtering and adsorption structure, which cannot actively and effectively purify the waste gas, reducing the efficiency of waste gas treatment, and the waste gas treatment is not thorough;

[0003] In the prior art, for example, announcement number CN210699450U proposes an exhaust device for waste gas in a petroleum refinery coking device. The present technical solution relates to an exhaust device for waste gas in a petroleum refinery coking device, and the technical solution is as follows: a connecting plate is fixedly connected to the inner wall of the treatment box, a first fixing rod is fixedly connected to the upper surface of the connecting plate, the first fixing rod is fixedly connected to a waterproof motor, the output shaft of the waterproof motor is fixedly connected to a rotating device, the bottom end of the rotating device is fixedly connected to a stirring device, and a hot plate is clamped on the right side of the inner wall of the treatment box. The exhaust device for waste gas in the petroleum refinery coking device realizes the rapid degradation of waste gas through the combined action of an air pump, an air pipe, a hot plate, a waterproof motor, a rotating shaft, a bearing, a stirring rod, a stirring blade, an activated carbon filter layer and an activated carbon adsorption layer, and the waste gas treatment and purification effect is better, thereby improving the waste gas treatment efficiency;

[0004] However, the exhaust device of the waste gas in the petroleum refining coking device of the prior art solution filters and absorbs the waste gas through the filter layer arranged inside, and finally discharges it through the exhaust pipe. After the device is used for a long time, the filter layer will absorb too much dust inside, resulting in poor filtering effect of the waste gas, and even affecting the normal operation of the device. In addition, the device directly discharges the treated sewage after absorbing the waste gas, without the step of treating solid particles such as waste residue in the waste water, resulting in the need for subsequent waste water treatment, resulting in low water utilization and high energy consumption.

[0005] In order to solve the above problems, the present application proposes an exhaust device based on chemical oil refining and coking. Utility Model Content

[0006] The utility model is intended to provide an exhaust device based on chemical oil refining and coking, which is mainly used to solve the problem that after the existing petroleum refining and coking device is used for a long time, the filtering effect of the filter layer on the exhaust gas will deteriorate, and the device does not have a step for treating solid particles such as waste residues in the waste water, resulting in the need for subsequent waste water treatment.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] An exhaust device based on chemical oil refining and coking comprises a box body, a filter layer is slidably connected inside the box body, one side of the filter layer extends out of the box body and is slidably connected to the box body, a pull block is fixedly connected to the side of the filter layer extending out of the box body, a symmetrical limiting component is slidably connected to one side of the box body, the limiting component comprises a symmetrical moving block slidably connected to one side of the box body, a T-shaped block is fixedly connected to the side of the moving block close to the box body, a T-shaped groove matching the T-shaped block is opened on one side of the box body, a symmetrical first spring is fixedly connected to the top of the T-shaped block, and the upper end of the first spring is connected to the The top of the inner wall of the T-slot is fixedly connected, and a sliding cavity is opened at the bottom of the moving block away from the box body. A wedge block is slidably connected inside the sliding cavity, and a symmetrical second spring is fixedly connected to the side of the wedge block close to the sliding cavity. The other end of the second spring is fixedly connected to the inner wall of the sliding cavity, and a buckle matching the wedge block is fixedly connected to one side of the box body. The bottom of the box body is fixedly connected to a fixed shell, and a collecting shell is slidably connected to the inside of the fixed shell. A filter plate is movably connected to the bottom of the inner wall of the collecting shell, and a liquid outlet pipe is fixedly connected to the bottom of the fixed shell, and the liquid outlet pipe is communicated with the interior of the fixed shell.

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: When the filter layer needs to be replaced after the device has been used for a long time, the wedge block is pressed to slide into the inner part of the sliding cavity on the moving block. When the wedge block completely enters the sliding cavity, the moving block will move upward under the action of the first spring. When the moving block is disengaged from the buckle, the pull block can be pulled outward to pull the filter layer out of the box body, so that people can clean or replace the filter layer conveniently. After inserting the clean filter layer into the box body, the moving block is pressed downward, and the wedge block is squeezed by the buckle and moves into the sliding cavity. When the wedge block is completely moved to the bottom of the buckle, the wedge block will pop up under the action of the second spring and engage with the buckle, which can play a better limiting role on the filter layer, thereby making the device more stable when in use. During the operation of the device, the wastewater flows into the fixed shell through the bottom of the box body, and the solid particles such as waste residue in the wastewater can be filtered above the filter plate through the collection shell slidably connected inside the fixed shell and the filter plate arranged inside the collection shell, and the wastewater is discharged through the liquid outlet pipe.

[0011] 2. Beneficial effects: Through the sliding connection between the filter layer and the box body, the filter layer can be removed from the inside of the box body after long-term use, so that people can clean or replace the filter layer conveniently. Through the fixed shell set at the bottom of the box body, solid particles such as waste residue in the wastewater can be processed, thereby making the utilization rate of the water body higher.

[0012] Preferably, one side of the fixed shell is rotatably connected to a symmetrical rotating plate, and one side of the collecting shell is fixedly connected to an L-shaped block matching the rotating plate. When the staff installs the collecting shell into the fixed shell, the rotating plate is rotated to connect it with the L-shaped block, which can play a good limiting role on the collecting shell, thereby effectively preventing the collecting shell from separating from the fixed shell during use of the device. When the staff needs to disassemble the collecting shell and clean the waste residue inside it, the rotating plate is rotated in the opposite direction to disengage it from the L-shaped block, and the collecting shell can be pulled out from the fixed shell, thereby making it convenient for people to clean the waste residue inside the collecting shell.

[0013] Preferably, a symmetrical observation port is provided on one side of the collecting shell, and an observation window is fixedly connected to the inner wall of the observation port, and the observation window is transparent. The observation window can be made of tempered glass. Since tempered glass has high strength and good transparency, the observation window provided on the collecting shell allows the staff to observe the amount of waste residue inside the collecting shell through the observation window during the operation of the device, so that people can clean the waste residue inside the collecting shell in time.

[0014] Preferably, sliders are fixedly connected on both sides of the filter layer, and slide grooves matching the sliders are fixedly connected on the inner wall of the box. The sliders arranged on both sides of the filter layer and the slide grooves opened on the inner wall of the box can play a better clamping effect on the filter layer, thereby making the filter layer more stable inside the box.

[0015] Preferably, the corners of the rotating plate are all rounded. By setting the corners of the rotating plate to be rounded, people's hand skin will not be scratched by the corners of the rotating plate when rotating the rotating plate, and people's hands will be more comfortable when rotating the rotating plate.

[0016] Preferably, a handle is fixedly connected to one side of the collecting shell, and the outer wall of the handle is provided with an anti-slip cover. People can more easily remove the collecting shell from the fixed shell by pulling the handle. The anti-slip cover provided on the outer wall of the handle can effectively increase the friction between people's hands and the outer wall of the handle, preventing people's hands from slipping when pulling the handle.
