Description

Technical Field

[0001] The utility model relates to the technical field of engineering vehicle exhaust gas treatment, in particular to an engineering machinery post-treatment device. Background Art

[0002] Automobile exhaust is the waste gas generated when the car is in use. It contains hundreds of different compounds, among which the pollutants are solid suspended particles. These solids are easy to adhere to the surface of the carrier, affecting the carrier to convert carbon monoxide and hydrocarbons in the exhaust gas into harmless CO2 and H2O, and NO into NO2, so that the vehicle's exhaust emissions do not meet the corresponding standards. Replacing the carrier will increase the cost of use. Utility Model Content

[0003] The utility model aims to provide a post-processing device for engineering machinery, which can automatically clean up the solid suspended particles attached to the carrier, reduce the use cost and improve the waste gas treatment efficiency.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: an engineering machinery post-processing device comprises a cylinder, an air inlet pipe and an air outlet pipe installed on the cylinder, two fixed rings arranged at intervals are installed on the outer wall of the cylinder, and a control component is arranged between the fixed rings;

[0005] The control assembly comprises a plurality of groups of electric slide rails distributed in a circumference, the electric slide rails are connected to the cylinder through a fixing ring, and a first magnetic block is provided on the electric slide rail;

[0006] A sliding track arranged along the direction of the air outlet pipe is provided on the inner wall of the cylinder at a position corresponding to each group of the electric slide rails, and a second slidable magnetic block is provided on the sliding track;

[0007] A carrier for converting carbon monoxide and hydrocarbons is provided inside the cylinder between the air inlet pipe and the air outlet pipe and connected to the inner wall of the cylinder through a bracket. A slidable annular particle collector is sleeved on the carrier, and the particle collector is connected to the second magnetic block.

[0008] Furthermore, a suspended particle detector is provided in the cylinder. When the suspended particle detector detects that the concentration of particulate matter in the cylinder reaches a certain threshold, it sends a signal to the electric slide rail, so that the particle collector moves along the surface of the carrier, collects the particulate matter attached to the surface of the carrier, and improves the combined treatment rate of the carrier and the exhaust gas.

[0009] Furthermore, a filter box is provided inside the cylinder between the carrier and the outlet pipe. After the particle collector collects the particulate matter on the carrier, it is moved to the position of the filter box. The airflow entering through the air inlet pipe can blow the particulate matter collected on the particle collector into the filter box for centralized collection and treatment.

[0010] Furthermore, the outer sleeve of the control component is provided with a detachable insulating cover, and the provision of the insulating cover can prevent the first magnetic block from adsorbing foreign objects, thereby increasing the service life of the first magnetic block.

[0011] Furthermore, a heat-insulating cotton is provided on the inner wall of the cylinder on one side of the air inlet pipe, which can absorb the heat of the airflow just entering the cylinder and improve the subsequent conversion efficiency of the airflow combined with the carrier.

[0012] Furthermore, a partition plate is provided between the carrier and the air inlet pipe, the side of the partition plate facing the carrier is the same width as the carrier, the side of the partition plate away from the carrier is the same width as the inner diameter of the cylinder, and both sides of the partition plate are provided with air holes for the passage of air flow. The provision of the partition plate can improve the contact between the air flow and the carrier more comprehensively.

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

[0014] 1. A control component is used in conjunction with a suspended particle detector in the cylinder. When the suspended particle detector detects that the particle concentration in the cylinder reaches a certain threshold, a signal is sent to the electric slide rail to make the particle collector move along the surface of the carrier to collect the particles attached to the surface of the carrier, thereby improving the combined treatment rate of the carrier and the exhaust gas.

[0015] 2. The first magnetic block is used to drive the second magnetic block on the sliding track to slide, so that the outside and the inside of the cylinder cooperate with each other to increase the sealing of the cylinder, while avoiding the installation of complex parts in the cylinder to occupy space and complicated maintenance.

[0016] 3. After the particle collector collects the particles on the carrier, it moves to the position of the filter box. The airflow entering through the air intake pipe can blow the particles collected by the particle collector into the filter box for centralized collection and treatment.

[0030] Preferably, a filter box 10 is provided inside the cylinder 1 between the carrier 7 and the outlet pipe 3.
