Description

Technical Field

[0001] The present application relates to the technical field of chemical waste liquid incineration, and specifically to a waste liquid spray gun. Background Art

[0002] A waste liquid spray gun refers to a high-efficiency combustion spray gun for chemical machine wastewater, salt-containing wastewater, waste liquid, and toxic liquid. It mainly sprays hazardous waste liquid into a waste liquid incinerator through an atomizing spray gun, and uses a controllable high-temperature chemical reaction process to destroy the molecular structure of various harmful substances and oxidize the waste liquid into carbon dioxide and water, thereby achieving environmentally friendly emissions.

[0003] The existing patent (Announcement No.: CN217329812U) discloses a high-viscosity waste liquid incineration spray gun, which involves the field of chemical waste liquid incineration, including a spray gun outer tube, a liquid inlet pipe and an air inlet pipe are arranged on the spray gun outer tube, the liquid inlet pipe is connected to a filter tube, a filter disc is arranged in the filter tube, a liquid inlet joint is connected to the bottom of the filter tube, an atomizing swirl blade is arranged in the spray gun outer tube, the atomizing swirl blade is located between the liquid inlet pipe and the air inlet pipe, and a nozzle is connected to one end of the spray gun outer tube. The utility model has low maintenance cost. Before the liquid enters the spray gun, the large particles in the liquid are filtered out by the filter disc, avoiding blockage inside the spray gun. Then, the atomizing swirl blade makes the atomized particles very uniform and fine, ensuring that the bottom is not wet, which greatly improves the efficiency of stock removal.

[0004] When the above-mentioned spray gun is in use, large particles in the liquid are filtered out through the filter to avoid blockage inside the spray gun. However, after a certain period of use, a large amount of particulate matter accumulates on the surface of the filter, which easily reduces the permeability of the filter, resulting in insufficient subsequent water pressure, causing the atomization effect to deteriorate, affecting the incineration effect of the waste liquid. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a waste liquid spray gun with advantages such as anti-clogging, which solves the problem that a large amount of particulate matter accumulates on the surface of the filter, which easily reduces the permeability of the filter, thereby causing insufficient subsequent water pressure, resulting in poor atomization effect and affecting the incineration effect of the waste liquid.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a waste liquid spray gun, comprising a spray gun outer tube, a filter disc is installed inside the spray gun outer tube, a cleaning pipe is rotatably connected inside the filter disc, and a plurality of circumferentially arranged dirt push boxes are connected to the outer surface of the cleaning pipe;

[0007] The outer surface of the sewage cleaning pipe is fixedly connected with a plurality of sewage suction pipes, each of which is located inside a sewage pushing box adjacent thereto, and the outer surface of each sewage suction pipe is provided with a plurality of sewage suction holes arranged at equal distances.

[0008] Through the above scheme, large particles in the waste liquid can be filtered through the filter disc, clogging of the atomizing nozzle can be avoided, and the service life of the atomizing nozzle can be increased. The flow rate sensor can be used to detect the flow rate inside the outer tube of the spray gun. When the flow rate decreases, the motor can automatically drive the cleaning pipe to rotate. The impurities on the surface of the filter disc can be collected inside the filter disc through the dirt pushing box. The dirt suction pipe can be used to facilitate users to quickly dispose of impurities.

[0009] Furthermore, a solenoid valve is installed inside the left end of the spray gun outer tube.

[0010] Through the above scheme, the outer tube of the spray gun can be closed by setting the electromagnetic valve.

[0011] Furthermore, a flow rate sensor is installed inside the right end of the spray gun outer tube.

[0012] Through the above scheme, the water flow velocity can be detected by setting the flow velocity sensor.

[0013] Furthermore, an atomizing swirl blade is installed inside the right end of the spray gun outer tube.

[0014] Through the above scheme, the waste liquid can be preliminarily atomized by the atomizing swirl blades.

[0015] Furthermore, an atomizing nozzle is installed at the right end of the spray gun outer tube.

[0016] Through the above scheme, by setting the atomizing nozzle, the waste liquid can be sprayed out in a smaller water mist.

[0017] Furthermore, an air inlet pipe is installed on the outer surface of the spray gun outer tube, and a flange is installed on the left end of the spray gun outer tube.

[0018] Through the above solution, the flange is provided to facilitate the user to connect with the external waste liquid delivery pipe.

[0019] Furthermore, the outer surface of the spray gun outer tube is rotatably connected to a power shaft, and bevel gears are installed at the bottom end of the power shaft and the left end of the cleaning pipe, and the two bevel gears are meshingly connected. The outer surface of the spray gun outer tube is fixedly connected to a fixing frame, and a micro motor is installed at the top of the fixing frame. The output end of the micro motor is fixedly connected to the power shaft, and the right end of the cleaning pipe is rotatably connected to an L-shaped tube, and a one-way valve is installed inside the L-shaped tube, and the one-way valve can be opened upward, and a sealing cover is installed at the top of the L-shaped tube.

[0020] Through the above solution and the provision of the sealing cover, it is convenient for the user to open the L-shaped tube to suck out dirt.

[0021] Furthermore, a microprocessor is installed on the outer surface of the spray gun outer tube, and the solenoid valve, micromotor and flow rate sensor are all electrically connected to the microprocessor.

[0022] Through the above scheme, the solenoid valve, micro motor and flow rate sensor can be controlled by setting the microprocessor.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] The waste liquid spray gun can filter large particles in the waste liquid through the filter disc, avoid clogging of the atomizing nozzle, and increase the service life of the atomizing nozzle. The flow velocity sensor can detect the flow velocity inside the outer tube of the spray gun. When the flow velocity decreases, the motor can automatically drive the cleaning pipe to rotate. The impurities on the surface of the filter disc can be collected inside the filter disc through the dirt pushing box. The dirt suction pipe can facilitate users to quickly handle the impurities.
