Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-5 The utility model provides a technical solution: a wastewater treatment device for a thermal power plant, comprising a shell 1, a water inlet pipe 2 is connected to the side of the shell 1, a collector 5 is connected to the upper surface of the shell 1, an agitator 4 is installed inside the shell 1, a filter plate 3 is detachably installed on the inner wall of the shell 1, a cleaning device 6 is provided on the surface of the filter plate 3, and a collecting device 7 is provided on the surface of the shell 1.

[0032] The specific settings and functions of the cleaning device 6 and the collecting device 7 will be described in detail below.

[0033] like Figure 1-Figure 4 As shown, the cleaning device 6 includes a connecting plate 63, which is slidably connected to the inner wall of the housing 1, and an electric telescopic rod 62 is installed on the upper surface of the housing 1. The output end of the electric telescopic rod 62 is fixedly connected to the connecting plate 63, and a scraper 64 is fixedly connected to the side of the connecting plate 63 away from the electric telescopic rod 62. By setting the electric telescopic rod 62, the connecting plate 63 and the scraper 64 can be controlled to move on the surface of the filter plate 3, so that the scraper 64 can be used to scrape off the impurities on the surface of the filter plate 3. Two inclined blocks 65 are fixedly connected to the surface of the scraper 64, and the other ends of the two inclined blocks 65 are fixedly connected to a rectangular plate 66. By setting the inclined block 65, the rectangular plate 66 can be connected to the scraper 64, so that the installation of the rectangular plate 66 can be completed.

[0034] A plurality of bristles 67 are fixedly connected to one side of the rectangular plate 66 close to the filter plate 3, and a mounting tube 61 is fixedly connected to one side of the housing 1 close to the electric telescopic rod 62. By providing the rectangular plate 66 and the bristles 67, the cleaning effect of the filter plate 3 can be increased, and by providing the mounting tube 61, the electric telescopic rod 62 can be fixed. Two cylinders 68 are fixedly connected to the inner wall of the housing 1, and a fixing plate 69 is fixedly connected to one end of the two cylinders 68 close to the bristles 67. By providing the cylinder 68, the fixing plate 69 can be connected to the housing 1, and by providing the fixing plate 69, the bristles 67 can be cleaned.

[0035] like Figure 1 and Figure 2 as well as Figure 5 As shown, the collecting device 7 includes a sealing plate 71, which is slidably connected to the inner wall of the shell 1, and a collecting box 72 is fixedly connected to the surface of the shell 1. By setting the sealing plate 71, the shell 1 can be closed, and by setting the collecting box 72, impurities can be collected. A fixing block 73 is fixedly connected to the surface of the sealing plate 71, and a mounting plate 74 is fixedly connected to the surface of the shell 1, and a limiting rod 75 is slidably connected to the inner wall of the mounting plate 74. The limiting rod 75 slidably connected to the inner wall of the mounting plate 74 can move, and by setting the limiting rod 75, the fixing block 73 and the mounting plate 74, the sealing plate 71 can be easily limited or released from the limit.

[0036] One end of the limiting rod 75 away from the fixing block 73 is fixedly connected with a pull plate 76, and a spring 77 is sleeved on the surface of the limiting rod 75, and the two ends of the spring 77 are respectively fixedly connected to the pull plate 76 and the mounting plate 74. By providing the pull plate 76, the limiting rod 75 can be easily moved, and by providing the spring 77, the position of the limiting rod 75 can be limited.

[0037] Working principle: When using the wastewater treatment device to treat the wastewater from a thermal power plant, first introduce the wastewater through the water inlet pipe 2, filter the wastewater through the filter plate 3, and then enter the shell 1, add the treatment liquid, and then start the agitator 4 to fully mix the treatment liquid and the wastewater, and then use the collector 5 to collect the gas generated by the wastewater treatment. When the wastewater is introduced into the shell 1 through the water inlet pipe 2, start the electric telescopic rod 62 in the installation tube 61, and the electric telescopic rod 62 drives the connecting plate 63 and the scraper 64 to move on the surface of the filter plate 3. At the same time, the movement of the scraper 64 drives the rectangular plate 66 to move through the inclined block 65, so that the bristles 67 clean the surface of the filter plate 3. After the bristles 67 clean the filter plate 3, the scraper 64 scrapes the surface of the filter plate 3 to remove impurities from the surface of the filter plate 3 as much as possible. Then the connecting plate 63 and the scraper 64 push the impurities close to the cylinder 68 and the fixed plate 69. When the scraper 64 approaches the fixed plate 69, the fixed plate 69 is between the scraper 64 and the rectangular plate 66, and the electric telescopic rod 62 is controlled to drive the scraper 64 away from the fixed plate 69. Under the blocking effect of the fixed plate 69, the impurities on the bristles 67 can be scraped off as much as possible. By setting up the cleaning device 6, the filter plate 3 can be cleaned synchronously during the process of using the wastewater treatment device to treat the wastewater of the thermal power plant, which can avoid the problem of clogging of the filter plate 3 as much as possible, thereby ensuring the normal treatment of the wastewater as much as possible.

[0038] When it is necessary to collect the impurities removed by the scraper 64, first pull the pull plate 76 to drive the limit rod 75 to slide on the inner wall of the mounting plate 74, so that the limit rod 75 moves away from the fixing block 73, thereby releasing the restriction on the position of the sealing plate 71. Then, the impurities are collected from the shell 1 into the collecting box 72, and the sealing plate 71 is moved close to the shell 1. The pull plate 76 is released, and under the action of the elastic force of the spring 77, the limit rod 75 moves close to the fixing block 73 to fix the sealing plate 71. By setting up the collecting device 7, after the impurities in the wastewater adhering to the filter plate 3 are cleaned, the cleaned impurities can be conveniently collected, and the accumulation of impurities can be avoided as much as possible, thereby further avoiding the blockage of the filter plate 3.
