DETAILED DESCRIPTION

[0024] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

The mobile cart 1 is provided with a gas-liquid separation tank 51 for secondary gas-liquid separation of the gas. The gas-liquid separation tank 51 is provided with a first pipeline connected to the liquid separation tank 5. One end of the three-way pipe 2 needs to be connected to the pipeline that needs to discharge the high-temperature liquid. The preferred three-way pipe 2 and the ball valve 3 can be made of stainless steel, and the other end needs to be connected to an external nitrogen pipe, and another end needs to be connected to a steel wire braided steam hose 52. The steel wire braided steam hose 52 is connected to the filter 61, and the liquid outlet of the filter 61 is connected to the liquid inlet of the condenser 4.

[0026] First, the high-temperature liquid to be discharged is connected to the wire braided steam hose 52, and then the nitrogen tank is connected to the three-way pipe 2. After the connection, the ball valve 3 connected to the nitrogen pipe is first opened, and the pipeline for continuously discharging the high-temperature liquid is pressurized. After the pressurization is completed, the ball valve 3 connected to the nitrogen is closed, and then the ball valve 3 connected to the wire braided steam hose 52 is opened to discharge the high-temperature liquid in the pipeline. When the high-temperature liquid passes through the filter 61, excess impurities in the liquid can be removed, and then the liquid after impurity removal enters the condenser 4 for cooling. The cooled liquid enters the liquid separation tank 5 for the first capture and separation, and then the separated gas is separated for the second time through the gas-liquid separation tank 51, so as to achieve the mobile discharge treatment of the high-temperature liquid, play a good role in the safe discharge efficiency of the polyester high-temperature liquid, and discharge the high-temperature liquid in the pipeline cleanly, thereby reducing the safety accidents caused by the pipeline not being discharged cleanly.

[0027] See also Figure 5-Figure 6 As shown, the anti-clogging mechanism 7 also includes a transmission rod 73; the transmission rod 73 is rotatably set on the filter 61, the input end of the transmission rod 73 is connected to the output end of the rotary driver 72 through a coupling, the threaded sheet is coaxially fixed to the transmission rod 73, and a filter plate 731 installed on the bearing at the end of the transmission rod 73 is provided in the filter 61, and a plurality of avoidance holes for high-temperature liquid to pass through are opened on the filter plate 731.

[0028] When the high-temperature liquid flows into the filter 61, the rotary driver 72 is started, thereby driving the transmission rod 73 to rotate. When the transmission rod 73 rotates, it can drive the coaxially fixed spiral blade and scraper rod to rotate. During the rotation of the spiral blade, the impurities flowing on the filter plate 731 can be transported in a vertical upward direction. At this time, the high-temperature liquid stays below the filter plate 731, and the impurities in the high-temperature liquid are driven by the spiral blade to rise in a spiral and are located above the filter plate 731.

[0029] See also Figure 5-Figure 6 As shown, the anti-clogging mechanism 7 further includes a scraper 74 and a collection pipe 75; the scraper 74 is arranged on the transmission rod 73 and fixed coaxially with the transmission rod 73; the collection pipe 75 is arranged on the filter 61. The scraper 74 is arranged on the transmission rod 73 and staggered with the spiral sheets without interfering with each other, and the collection pipe 75 is preferably made of stainless steel.

[0030] When the transmission rod 73 rotates, it can drive the scraper rod to rotate synchronously. Since the scraper rod is fitted inside the filter 61, the transmission rod 73 can drive the scraper rod to clean and scrape the inner wall of the filter 61 when it rotates, so that the inner wall of the filter 61 is kept clean at all times. When high-temperature impurities rise due to the rotation of the spiral blades, the impurities in the high-temperature liquid can be driven to be discharged through the collection pipe 75. In this process, the impurities in the liquid can flow to the recovery box 76 through the recovery pipe, so as to effectively remove the impurities in the filter.

[0031] See also Figure 3-Figure 4 As shown, the anti-clogging mechanism 7 also includes a recovery box 76 and a first connecting pipe 77; the recovery box 76 is arranged on the mobile cart 1; the first connecting pipe 77 is arranged on the recovery box 76 and is connected to the condenser 4, and a filter screen 761 is slidably arranged on the recovery pipe for filtering impurities dropped in the collection pipe 75, and the filter screen 761 is detachably arranged on the recovery box 76, and an installation groove is opened on the recovery box 76 for inserting and installing the filter screen 761.

[0032] When the impurities in the recovery pipe flow to the recovery box 76, the filter screen 761 provided on the recovery box 76 can perform secondary filtration on the impurities, and the filtered liquid can be sent to the condenser 4 through the first connecting pipe 77, and the condenser 4 can cool the liquid.

[0033] See also Figure 7-Figure 8 As shown, the lifting mechanism 8 includes a cylinder 81 and a push rod 82; the cylinder 81 is arranged on the mobile cart 1; the push rod 82 is slidably arranged on the cylinder 81 in the vertical direction, and the mobile cart 1 is provided with a first positioning rod 811 for installing and supporting the cylinder 81 to make an inclined angle, and the liquid separation tank 5 is provided with a second positioning rod 812 rotatably connected to the push rod 82, and the liquid separation tank 5 is provided with a discharge port for discharging impurities accumulated and attached inside, and the condenser 4 is provided with a second connecting pipe connected to the liquid diversion tank.

[0034] When the cooled liquid flows into the liquid separation tank 5 through the second connecting pipe, the condenser 4 is provided with a cooling spray pipe located in the separation tank. At this time, the high-temperature gas and liquid discharged into the liquid separation tank 5 can be captured and separated, and the captured and separated gas can enter the gas-liquid separation tank 51 again for secondary separation and discharge.

[0035] See also Figure 7-Figure 8 As shown, the lifting mechanism 8 also includes a mounting plate 83 and a first hinged rod 84; the mounting plate 83 has a pair and is arranged on the liquid separation tank 5 facing each other; the hinged rod is arranged between the pair of mounting plates 83, and the mobile cart 1 is provided with a fixed block 841 for sealing the impurity discharge port of the liquid separation tank 5, the fixed block 841 matches the shape of the impurity discharge port, and the liquid separation tank 5 is connected to the hinged rod.

[0036] When it is necessary to discharge the wastewater precipitated in the liquid separation tank 5, the cylinder 81 is started, and then the push rod 82 is extended and moved. When the push rod 82 is extended and moved, the liquid separation tank 5 can be lifted up at an inclined angle along the hinge rod through the first positioning rod 811 and the second positioning rod 812. When lifted up, the wastewater in the liquid separation tank 5 can be discharged through the impurity discharge port. After discharge, the push rod 82 is reset, and the liquid separation tank 5 returns to the initial position. After resetting, the fixed block 841 can contact and seal the impurity discharge port, so as to achieve rapid cleaning of the liquid separation tank 5 without manual cleaning.
