Description

Technical Field

[0001] This utility model relates to the field of loader exhaust gas collection technology, specifically an exhaust gas collection device for a four-pillar loader for well-drilling. Background Technology

[0002] Underground loaders, as a common type of engineering machinery, are widely used in mining enterprises such as coal mines, iron mines, lead-zinc mines, and non-ferrous metal mines. These mine environments are typically characterized by confined spaces, poor air circulation, high humidity, and abundant dust. Under such working conditions, the loader's power system and exhaust emission system face numerous challenges.

[0003] Existing technology discloses a vehicle exhaust gas collection device (publication number CN102434251A). It includes an exhaust gas inlet connected to the vehicle's exhaust port, a buffer chamber connected to the exhaust gas inlet, and a compression chamber connected to the buffer chamber. A one-way piston is installed in the compression chamber, and the push rod of the one-way piston is connected to a drive device controlled by a control circuit. The compression chamber is also connected to a gas collection chamber. A one-way valve is installed at the connection between the compression chamber and the gas collection chamber, allowing gas to flow from the compression chamber to the gas collection chamber. An exhaust port and an exhaust plug are installed on the gas collection chamber. Pressure sensors connected to the control circuit are installed in both the buffer chamber and the gas collection chamber. This is a vehicle exhaust gas collection device with a simple structure, ingenious design, and reasonable layout, capable of effectively collecting vehicle exhaust gases.

[0004] The aforementioned exhaust gas collection device features a three-stage recovery structure consisting of a buffer chamber, a compression chamber, and a gas collection chamber. It can collect vehicle exhaust gas relatively smoothly and effectively. However, the device only uses a single collection pipe for exhaust gas collection, resulting in low collection efficiency. Furthermore, the device lacks a detachable filter component, and there is no subsequent processing after collection; the gas must be discharged into a treatment device for further processing. Consequently, its performance in use is unsatisfactory and requires improvement. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 The present invention provides the following technical solution:

[0024] A tail gas collection device for a four-pillar downhole loader includes a collection box 1, a transmission pipe 2 on the side of the collection box 1, a tail gas intake device 3 on the side of the transmission pipe 2, and an internal filtration device 4 on the top of the tail gas intake device 3.

[0025] The exhaust gas intake device 3 includes a carrier box 301, an intake bucket 302, a placement box 303, an air pump 304, an annular connecting air pipe 305, a diversion airbag 306, an inner ring 307, a diversion and collection air pipe 308, a mounting groove 309, a docking column 310, and a protective cylinder 311. The carrier box 301 is fixedly connected to the right side of the transmission pipe 2, the intake bucket 302 is fixedly connected to the top of the carrier box 301, the placement box 303 is fixedly connected to the front of the intake bucket 302, and the air pump 304 is fixedly connected to the placement box 303. At the top of the suction bucket 302, an annular connecting air pipe 305 is connected to the inside of the air pump 304. A diversion airbag 306 is fixedly connected to the top of the suction bucket 302. An annular connecting air pipe 305 is connected to the inside of the diversion airbag 306. A diversion collecting air pipe 308 is fixedly connected to the inner wall of the diversion collecting air pipe 308. An installation groove 309 is opened at the top of the suction bucket 302. A protective cylinder 311 is fixedly connected to the top of the docking post 310. The diameter of the installation groove 309 is adapted to the diameter of the docking post 310. The docking post 310 is inserted into the suction bucket. Inside component 302, a connecting coarse air tube is fixedly connected to one end of the diversion airbag 306 near the inner ring 307. A placement tray is fixedly connected to the top of the suction bucket 302, and the inner ring 307 is fixedly connected to the top of the placement tray. The end of the coarse air tube away from the diversion airbag 306 is fixedly connected to the surface of the diversion collection air tube 308. When the air pump 304 is activated, a negative pressure suction is generated. This suction is extended into the diversion collection air tube 308 through the transmission of the annular connecting air tube 305, the diversion airbag 306, and the connecting coarse air tube, enabling diversion adsorption. It can accelerate the adsorption efficiency. The connecting pipe connects the diversion airbag 306 and the diversion collection air pipe 308 to ensure normal gas transmission. The inner wall of the protective cylinder 311 has a threaded groove at the top. The connecting block 402 has a threaded connection hole with the same diameter as the threaded groove. The mounting bolt 403 is threaded into the threaded groove and the threaded connection hole. The filter screen 401 can be disassembled. The components that can be disassembled are the connecting block 402 and the mounting bolt 403, which facilitates installation and disassembly for cleaning to ensure the filtration effect of the device.

[0026] The internal filtration device 4 includes a filter screen 401, a connecting block 402, and mounting bolts 403. The filter screen 401 is connected to the inside of the protective cylinder 311, and the connecting block 402 is fixedly connected to the top of the filter screen 401.

[0027] In use, the exhaust gas suction device 3 on the side of the transmission pipe 2 can perform negative pressure adsorption, absorbing the exhaust gas and passing it through the internal filtration treatment device 4 before entering the transmission pipe 2. Finally, it is collected inside the collection box 1 to complete the exhaust gas collection process. During adsorption, the exhaust gas suction device 3 is required. Before starting, the docking column 310 needs to be aligned with the mounting groove 309 on the top of the suction bucket 302 and inserted. The protective cylinder 311 is then placed in place. Then, the air pump 304 can be started to generate negative pressure suction. With the help of the annular connecting air pipe 305, the diversion airbag 306, and the connecting coarse suction pipe, the suction is extended into the diversion collection air pipe 308, enabling diversion adsorption. The adsorption and delivery are carried out through the six diversion collection air pipes 308. The adsorption efficiency is accelerated by the transmission pipe 2, allowing the device to set up multiple collection pipes when collecting exhaust gas, resulting in high efficiency. An internal filtration device 4 is installed inside the protective cylinder 311, which can pre-filter the adsorbed gas before further processing. The internal filter plate 401 is installed inside the protective cylinder 311 through the cooperation of the connecting block 402 and the mounting bolt 403. During adsorption, the adsorbed gas can be filtered by passing through the filter plate 401. The filter plate 401 can be disassembled for easy cleaning to ensure the filtration effect of the device. The device is equipped with a detachable filter component, which allows for subsequent operations after collection. Pre-treatment can be performed without discharge into the treatment device, which can reduce the time spent on subsequent processing.
