Description

Technical Field

[0001] The utility model relates to the technical field of tail gas treatment, in particular to an anti-clogging air intake device for tail gas treatment equipment. Background Art

[0002] Existing exhaust gas treatment equipment primarily burns and filters waste gas before discharging it. The main process is as follows: the waste gas is pumped into the equipment's reaction chamber via a vacuum pump. Natural gas and oxygen are then introduced into the chamber in appropriate proportions, where combustion converts the waste gas into a non-toxic and harmless gas. Finally, the waste gas is washed and dried before being discharged.

[0003] The air inlet pipe of the exhaust gas treatment equipment is generally an L-shaped pipe. When the exhaust gas enters the reaction chamber through the air inlet pipe, the dust it carries is easily accumulated at the air outlet of the pipe. The existing method generally treats the dust by setting a scraper and blowing air. However, during use, each pipe needs to be equipped with a motor and air blowing. First, the motor drives the scraper to rotate around the axis of the pipe inside the pipe to scrape off the dust, and then nitrogen is introduced to blow the dust into the reaction chamber, which increases the equipment cost. Summary of the Invention

[0004] The purpose of the utility model is to provide an anti-clogging air intake device for exhaust gas treatment equipment to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an anti-clogging air intake device for exhaust gas treatment equipment, comprising an air intake cavity and a plurality of air intake components arranged on the outer peripheral wall of the air intake cavity, the air intake components comprising two air intake pipes arranged side by side, and the air intake pipes each comprise a horizontal section and a vertical section vertically arranged at the top end of the horizontal section, one end of the horizontal section is sealed, and the other end is connected to the air intake cavity, cleaning parts are slidably provided inside the horizontal sections of the two air intake pipes, a linear driving part is provided on the outside of any one of the air intake pipes for pushing the cleaning part to slide back and forth along its axial direction inside the horizontal section, and a driving mechanism is provided on the outside of the air intake pipe for driving the other cleaning part to slide in the opposite direction.

[0006] Furthermore, the driving mechanism includes a housing, a gear rotatably arranged inside the housing, and two racks respectively arranged on both sides of the gear, the racks and the gear are engaged with each other, and the two racks are respectively arranged along the axis parallel to the two horizontal sections, and one side of the bottom end of the two racks is fixedly connected to the cleaning member through a vertical rod and a horizontal rod.

[0007] Furthermore, the shell is horizontally fixed above the horizontal section through a support plate, and a strip-shaped through hole is provided through the bottom end of the shell to accommodate the vertical rod sliding back and forth along the axial direction of the horizontal section.

[0008] Furthermore, the cleaning member is a cylindrical structure that fits tightly with the inner side wall of the horizontal section. When one end of the cleaning member extends into the interior of the air inlet cavity, the outer side wall of the cleaning member covers the bottom opening of the vertical section.

[0009] Furthermore, the air inlet cavity is a cylindrical structure with an opening at the bottom, and a mounting plate is vertically bent at the edge of the opening.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] By arranging several groups of air intake pipes side by side, cleaning parts are provided inside the air intake pipes along their horizontal axial sliding paths, which can scrape off the dust adhering to the horizontal section at the bottom of the air intake pipes and push it into the air intake cavity at the same time, thus reducing pipe blockage and eliminating the need for blowing, thereby reducing working costs.

[0012] Through the driving mechanism, the inside of the two intake pipes can be cleaned and ventilated alternately, reducing equipment costs, avoiding interruption of exhaust gas treatment, and improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
