Description

Technical Field

[0001] The utility model relates to the technical field of fume treatment of a setting machine, in particular to an energy-saving fume dust removal and cooling device for a setting machine. Background Art

[0002] When the setting machine is running, it usually generates a large amount of waste gas and waste dust, which has high temperature and serious pollution. In order to reduce the pollution of waste gas and waste dust, electrostatic purification and other equipment are generally used to treat the waste gas, so that the exhausted gas is clean or has very little pollution.

[0003] A finned radiator for cooling is arranged at the front end of the purifier. However, since there are a large amount of oil and smoke particles in the exhaust gas, and the finned radiator does not have a good dust and oil removal effect, a large amount of oil will accumulate on the interface connecting the purifier. Over time, thick oil will accumulate on the inner wall of the interface, affecting the passability of the exhaust smoke, resulting in insufficient exhaust smoke intake pressure of the purifier. The air intake pressure of the purifier can only be increased by adding a negative pressure fan. The fan consumes a lot of power and energy, and the oil in the purifier needs to be cleaned frequently. Utility Model Content

DETAILED DESCRIPTION

[0020] The utility model provides an energy-saving fume dust removal and cooling device for a setting machine, such as Figure 1-3 As shown, it includes a connecting pipe 1, a dust collector 3, and a purifier 2 arranged in sequence along the direction of the smoke outlet of the setting machine. The purifier 3 is a high-voltage electrostatic precipitator currently commonly used on the market. The connecting pipe 1 is arranged horizontally, and a spray device 4 is arranged in the horizontal connecting pipe 1 along its length direction. The spray device 4 is composed of a number of spiral atomizing nozzles 8 arranged at intervals. The several spiral atomizing nozzles are connected to the water source through the spray pipe. The spiral atomizing nozzle is an existing commercially available product. The water mist sprayed by the spiral atomizing nozzle is spiral-shaped and can cover various areas in the connecting pipe 1 to prevent the occurrence of spraying dead angles. At the bottom of the connecting pipe 1, there are several sewage pipes for discharging the precipitated oil and dirt arranged at intervals along its length direction. The sewage pipe is connected to the water tank 51.

[0021] The device also includes a sewage collection tank 5 and a cooling water recovery tank 6.

[0022] Specific as Figure 2 As shown, the dust collector 3 includes a box body 31, a plurality of dust removal plates 32 bent in an S shape, and a cooling water recovery box 6. The bending of the dust removal plates 32 can be as follows: Figure 2 The bridge or wave shape shown. A plurality of dust removal plates 32 are arranged in the box body 31 at a longitudinal interval, and a flue gas channel 33 is formed between two adjacent dust removal plates 32. The two ends of the flue gas channel 33 are respectively connected to the connecting pipe 1 and the purifier 2. The inside of the dust removal plate 32 is a heat exchange channel 34. The inlet and outlet ends of the heat exchange channel 34 are connected to the cooling water recovery tank 6 through the water inlet pipe 35 and the water outlet pipe 36. The water inlet pipe 35 is provided with a power pump 7. The power pump 7 is a water pump. Air can also be ventilated in the dust removal plate 32 to cool the flue gas. When air is ventilated, the power pump 7 is an air pump, and the outlet end of the heat exchange channel 34 is directly discharged into the atmosphere.

[0023] A dust collector 3 is added between the connecting pipe 1 and the purifier 2. The dust collector 3 adopts an S-shaped bent dust removal plate structure to replace the fin cooling device currently on the market, which reduces the large resistance and thus saves the negative pressure fan. The air is only supplied by the external exhaust fan of the setting machine, thereby achieving the effect of saving electricity and energy. At the same time, since there is no large resistance, the rotation speed of the setting fan is reduced, thereby reducing the energy consumption of the setting machine. At the same time, the dust removal plate 32 can greatly increase the smoke and oil interception and purification effect at this section, so that the oil and particulate matter content in the smoke entering the purifier 2 is less, preventing the purifier 2 from being blocked, and at the same time reducing the load of high-voltage static electricity, thereby achieving a power saving effect.

[0024] The dust removal plate 32 is made of stainless steel, which effectively improves its heat exchange effect.

[0025] The top of the box body 31 is provided with several rows of spray groups 37 corresponding to the dust removal plates 32 one by one. The spray groups 37 adopt the same model as the spiral atomizing nozzles arranged on the above-mentioned connecting pipe 1. The flow rate of the flue gas can be slowed down when passing through the dust removal plates 32, and oil stains and particulate matter will adhere to the dust removal plates 32 under the action of the spray.

[0026] like Figure 3 As shown, the device further includes a sewage collecting device 5, the water outlet of the sewage collecting device 5 is connected to the spray group 37, and the bottom sewage pipe of the box body 31 is refluxed and connected to the sewage collecting device 5. The spray group 37 is used to spray the dust removal plate 32 and the flue gas channel 33, and the oil and particulate matter in the flue gas are settled and flushed into the sewage collecting device 5 together with the oil attached to the dust removal plate 32.

[0027] like Figure 3 As shown, the sewage collection device 5 includes a water tank 51, a scraper 55, a lead screw slide rail module 56, a sleeve 57, a slide rod 58 and a float 59. The sewage sprayed from the box body 31 enters the water tank 51 through the sewage pipe, and re-enters the spray group 37 after scraping the oil. The lead screw slide rail module 56 is composed of components such as a lead screw, a slide rail, a motor, and a nut. It is an existing mature module. The lead screw slide rail module 56 is used to drive the slide sleeve 57 to move along the length direction in the water tank 51. The slide sleeve 57 is set on the nut of the lead screw slide rail module 56. The slide rod 58 is vertically slidably adapted on the slide sleeve 57. The slide rod 58 is T-shaped, and a limit ring is set at the bottom of the slide sleeve 57 to prevent the slide rod 58 from sliding out. The scraper 55 is set at the bottom of the slide rod 58 and corresponds to the liquid surface. The float 59 is set on the scraper 55. The scraper 55 is lower than the float, and when the float 59 floats on the liquid surface, the scraper 55 extends into the liquid surface by about 2 cm. By arranging the float 59, the scraper 55 can be raised and lowered synchronously with the rise and fall of the liquid surface.

[0028] An oil outlet 52 is provided on one side of the water tank 51 corresponding to the scraper 55. Slide rails are vertically arranged on both sides of the oil outlet 52. A baffle 53 is arranged at the oil outlet 52. Both ends of the baffle 53 are vertically slidably adapted on the slide rails. A cylinder 54 for controlling the lifting of the baffle 53 is arranged on the water tank 51. When it is necessary to scrape the oil in the water tank 51, the upper edge of the baffle 53 can be lowered to be flush with the oil, and then the lead screw slide rail module is used to drive the scraper 55 to scrape the oil from the water tank 51 to the oil outlet 52.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
