Since the filter net and the filter frame are both arranged in an inclined structure, this shaking not only helps to shake off the impurities attached to the filter net.

Description

Technical Field

[0001] The utility model relates to the technical field of denitrification deep bed filter, in particular to an anti-clogging denitrification deep bed filter. Background Art

[0002] Denitrification deep bed filter is a biological filter with denitrification and denitrification function, mainly used in deep treatment and filtration processes in domestic and industrial sewage treatment. Its core function is to effectively remove nitrogen and other pollutants in sewage and improve water quality through the combination of biological oxidation denitrification and deep bed filtration.

[0003] Due to the characteristics of the internal filter material layer, the existing denitrification deep bed filter is prone to accumulate a large amount of suspended solids and organic matter during use, resulting in clogging of the filter material pores, which in turn affects the normal filtering effect of the filter, which not only reduces the treatment efficiency of the filter, but also may cause a series of operational problems. Secondly, cleaning the existing denitrification deep bed filter is also very troublesome. Due to the complex structure of the filter, the cleaning work often requires a lot of manpower and time. Moreover, the filter material layer may be damaged during the cleaning process, further shortening the service life of the filter. Therefore, we propose a denitrification deep bed filter that is anti-clogging. Utility Model Content

[0004] The purpose of the utility model is to provide a blockage-resistant denitrification deep bed filter to solve the problem proposed in the above background technology that due to the characteristics of the internal filter material layer, the existing denitrification deep bed filter is prone to accumulate a large amount of suspended matter and organic matter during use, resulting in blockage of the filter material pores, thereby affecting the normal filtering effect of the filter, which not only reduces the treatment efficiency of the filter, but also may cause a series of operating problems. Secondly, cleaning the existing denitrification deep bed filter is also very troublesome. Due to the complex structure of the filter, cleaning work often requires a lot of manpower and time. Moreover, the filter material layer may be damaged during the cleaning process, further shortening the service life of the filter.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a blockage-resistant denitrification deep bed filter, comprising a filter body, a collecting box fixedly installed on one side of the filter body, a filter frame arranged near the top of the filter body, a filter net fixedly installed on one side of the filter frame, a material drop opening at the top of the filter frame, springs fixedly connected to the front and rear ends of both sides of the top of the filter frame, a cam arranged inside the collecting box, a motor fixedly installed on the front surface of the collecting box, a purification box fixedly installed on the top of one side of the collecting box, a fan fixedly installed on the top of the purification box, and activated carbon particles arranged at the bottom of the purification box.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] The anti-clogging denitrification deep bed filter is designed with a collection box, a filter frame, a filter screen, a feed port, a motor, a cam, and a spring. When the motor is started, the cam is driven to rotate. Due to the characteristics of the spring, when the raised portion of the cam contacts the filter frame, the filter frame is subjected to a certain thrust and vibrates. This vibration is transmitted to the filter screen through the filter frame, causing the filter screen to shake. Since the filter screen and the filter frame are both arranged in an inclined structure, this shaking not only helps to shake off impurities attached to the filter screen, but also ensures that the shaken impurities slide smoothly into the collection box. In this way, the filter achieves the control of impurities entering the filter body. Impurities are initially filtered, which greatly reduces the burden on subsequent filter layers and effectively avoids the clogging of filter layers and filter screens. The design of the purification box, fan and activated carbon particles, when a certain amount of impurities accumulate in the collection box, some bad gases may be produced. By starting the fan, the gas in the collection box can be drawn into the purification box. In the purification box, the gas is adsorbed and filtered by the activated carbon particles, and the harmful substances and odors therein are effectively removed. Finally, the purified gas is discharged through the exhaust slot, which not only ensures the freshness of the internal environment of the collection box, but also meets environmental protection requirements and realizes the harmless treatment of exhaust gas.

[0014] See also Figure 1-4 The utility model provides a technical solution: a blockage-resistant denitrification deep bed filter, comprising a filter body 1, a collecting box 2 is fixedly installed on one side of the filter body 1, a filter frame 3 is arranged near the top of the filter body 1, a filter net 4 is fixedly installed on one side of the filter frame 3, a material drop port 6 is opened on the top of the filter frame 3, the front and rear ends of both sides of the top of the filter frame 3 are fixedly connected with springs 10, a cam 8 is arranged inside the collecting box 2, a motor 7 is fixedly installed on the front surface of the collecting box 2, a purification box 11 is fixedly installed on the top of one side of the collecting box 2, a fan 12 is fixedly installed on the top of the purification box 11, and activated carbon particles 13 are arranged on the bottom of the purification box 11.

[0015] A groove 5 is provided at the top position on the side opposite to the filter body 1 and the collecting box 2. The two grooves 5 are connected. One side of the filter frame 3 penetrates the two grooves 5 and extends to the interior of the collecting box 2, so that the filter frame 3 can smoothly pass through the filter body 1 and the collecting box 2, thereby achieving preliminary filtration and collection of impurities and ensuring the normal operation of the filter.

[0016] The drop port 6 is located on one side of the filter screen 4. The filter frame 3 and the filter screen 4 are both arranged with an inclined structure, so that the impurities filtered by the filter screen 4 can smoothly slide to the drop port 6 and then enter the collection box 2, effectively avoiding the accumulation of impurities in the filter tank body 1.

[0017] The upper ends of the four springs 10 corresponding to the inner walls of the collection box 2 and the filter tank body 1 are fixedly connected with connecting plates 9, and the upper ends of the four springs 10 are fixedly connected to the front and rear ends of the bottom of the two connecting plates 9 respectively. Through the cooperation of the springs 10 and the connecting plates 9, the filter frame 3 can shake when pushed by the cam 8, thereby enhancing the filtering effect on impurities.

[0018] The cam 8 is located on one side of the lower end of the filter frame 3, and the motor 7 is located at the front end of the cam 8. The motor 7 is fixedly connected to an output shaft through the output end of the rear surface of the motor 7. The rear end of the output shaft penetrates into the interior of the collection box 2 and is fixedly connected to the front surface of the cam 8. The motor 7 drives the cam 8 to rotate, providing power for the shaking of the filter frame 3 to achieve the cleaning of impurities.

[0019] An exhaust pipe 14 is fixedly connected to the center of the bottom of the purification box 11, one end of the exhaust pipe 14 is fixedly connected to the center position of one side of the collecting box 2, the inner top of the exhaust pipe 14 and the top position in the purification box 11 are fixedly connected with a partition 15, a through hole is opened on the top of the partition 15, and an exhaust groove is opened on the top of the purification box 11. The partition 15 can limit the activated carbon particles 13, so that the gas in the collecting box 2 can enter the purification box 11 through the exhaust pipe 14, and after being filtered by the activated carbon particles 13, it is discharged from the exhaust groove, thereby achieving the purpose of purifying the gas.

[0020] Slide blocks 17 are fixedly connected at the front end and the rear end of the center of both sides of the filter frame 3. Slide grooves 16 are respectively provided on the inner walls of the collection box 2 and the filter tank body 1 at one end of the four slide blocks 17. The four slide blocks 17 are slidably connected to the four slide grooves 16 respectively. The cooperation between the slide blocks 17 and the slide grooves 16 makes the filter frame 3 more stable during movement, ensuring the smooth filtering and cleaning process. The supporting plate 18 is used to support the filter material layer 19 to ensure the stability and filtering effect of the filter material layer 19. The outlet pipe 20 is used to discharge the clean water filtered by the filter material layer 19 to achieve sewage treatment.

[0021] A support plate 18 is fixedly connected to the bottom of the filter tank body 1, and a filter material layer 19 is arranged on the upper end of the support plate 18. A water outlet pipe 20 is fixedly connected to the bottom of one side of the filter tank body 1. A cover plate is fixedly installed on the bottom of the front surface of the purification box 11 by screws, and a box door is movably installed on the bottom of the front surface of the collection box 2. The design of the cover plate facilitates cleaning and maintenance of the interior of the purification box 11; the box door facilitates cleaning and processing of impurities in the collection box 2, thereby keeping the overall cleanliness and efficient operation of the filter tank.

[0022] Working principle: When sewage enters the filter tank body 1, it is firstly filtered through the filter screen 4. Since the filter frame 3 and the filter screen 4 are both inclined structures, larger impurities in the sewage can smoothly slide to the drop port 6 of the filter frame 3 when passing through the filter screen 4, and then enter the collection box 2 through the groove 5, thereby effectively avoiding the accumulation of impurities in the filter tank body 1. At the same time, the start motor 7 drives the cam 8 to rotate. The cam 8 continuously contacts the filter frame 3 during the rotation process. Since the two sides of the top of the filter frame 3 are connected to the connecting plate 9 through the spring 10, the elasticity of the spring 10 allows the filter frame 3 to shake when it is pushed by the cam 8. This shaking not only further enhances the filtering effect of the filter screen 4 on impurities, but also can remove impurities attached to the filter screen. 4 is shaken off into the collection box 2. During the filtering process, the supporting plate 18 at the bottom of the filter tank body 1 supports the filter material layer 19 to ensure that the sewage can evenly pass through the filter material layer 19 for deep filtration. The clean water filtered by the filter material layer 19 is discharged through the outlet pipe 20 to achieve sewage treatment. In addition, the gas in the collection box 2 enters the purification box 11 through the exhaust pipe 14. The fan 12 in the purification box 11 draws the gas through the activated carbon particles 13. The activated carbon particles 13 adsorb and filter the harmful substances in the gas. The purified gas is discharged through the exhaust groove, which ensures the freshness of the internal environment of the filter tank. When it is necessary to clean the impurities in the collection box 2, just open the box door to clean out the impurities in the collection box 2.

[0023] In summary: the anti-clogging denitrification deep bed filter, through the design of the collection box 2, filter frame 3, filter screen 4, drop port 6, motor 7, cam 8, and spring 10, when the motor 7 is started, the cam 8 will be driven to rotate. Due to the characteristics of the spring 10, when the raised part of the cam 8 contacts the filter frame 3, the filter frame 3 will be subjected to a certain thrust and vibrate. This vibration is transmitted to the filter screen 4 through the filter frame 3, causing the filter screen 4 to shake. Since the filter screen 4 and the filter frame 3 are both inclined structures, this shaking not only helps to shake off the impurities attached to the filter screen 4, but also can ensure that the shaken impurities slide smoothly into the collection box 2. In this way, the filter tank realizes the main control of the impurities entering the filter tank. The impurities in the body 1 are initially filtered, which greatly reduces the burden of the subsequent filter material layer 19 and effectively avoids the clogging problem of the filter material layer 19 and the filter net 4. The design of the purification box 11, the fan 12 and the activated carbon particles 13, when a certain amount of impurities accumulate in the collection box 2, some undesirable gases may be generated. By starting the fan 12, the gas in the collection box 2 can be drawn into the purification box 11. In the purification box 11, the gas is adsorbed and filtered by the activated carbon particles 13, and the harmful substances and odors therein are effectively removed. Finally, the purified gas is discharged through the exhaust groove, which not only ensures the freshness of the internal environment of the collection box 2, but also meets the environmental protection requirements and realizes the harmless treatment of the exhaust gas.
