[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When a large amount of blockage occurs at the bottom of the filter, the incoming water flow will impact and squeeze the filter, thereby pushing the filter. When the filter reaches a certain position, the elastic control component controls the driving component to start, and drives the rack to move upward through the driving gear, thereby driving the cleaning component fixedly connected between the racks to clean the blockage on the filter component, thereby ensuring the filtering effect. The present invention can automatically clean according to the blockage situation, without manual observation and manual cleaning, reducing the use of manpower, while ensuring the efficiency of sewage purification;

[0021] 2. The pressure on the filter assembly can be used to detect the blockage. When the blockage reaches a certain level, the extrusion rod and the contact rod come into contact, and the cleaning assembly is automatically started. This method can automatically know when the inside of the purification treatment box needs to be cleaned, and blockage caused by not cleaning for a long time can be avoided. Automatic cleaning can be performed to ensure the efficiency of the entire purification treatment.

[0022] 3. During the filtering process, a large amount of impurities will be blocked by the filter components and sink. The sunken impurities will fall and accumulate on the bearing bar. At the same time, the bearing bar is set in a J shape, which can block the impact of the water flow to a certain extent, thereby avoiding the water flow from impacting the collected sediment again, ensuring the cleaning effect during cleaning;

[0023] 4. When the rack is driven by the driving gear, the entire cleaning assembly will move upward. During the upward movement, the scraper bar will scrape and clean the surface of the filter, thereby clearing the blockage on the filter. The cleared blockage will fall onto the bearing bar and be finally cleaned;

[0024] 5. The energized spiral column contracts, driving the drive gear to move toward the inside of the opening. The drive gear will mesh with the rack during the movement, and the drive gear will limit the filter assembly. When the cleaning is completed, the control module will generate a signal at a fixed time, so that the control module is powered off, so that the energized spiral column is reset, so that the drive gear is separated from the rack, and the restriction on the elastic control assembly is released. At this time, the elastic control assembly will drive the filter assembly to reset, and the meshing connection between the drive gear and the rack can be controlled by powering on;

[0025] 6. The deflected bearing bar transfers the internal impurities to the inside of the collection box. Since the collection port of the collection box is tilted downward, the introduced impurities can be guided to the inside of the collection box to avoid the accumulation of impurities at the collection port, ensuring the collection and cleaning of impurities. Regular automatic collection and cleaning can extend the detection cycle, reduce the frequency of detection, and ensure the purification effect;

[0026] 7. When the filter moves, the connecting rod and the scraper ring will move with the filter. After the filter is cleaned, the filter will reset under the elastic action of the elastic control component. At this time, the scraper ring moving with the filter will scrape and clean the inner wall of the purification treatment box, separating the adhesion from the purification treatment box, making it convenient to collect and clean the adhesion next time.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] Reference Figure 1-Figure 10 , a sewage purification device suitable for the food and beverage industry, comprising: a purification treatment box 1, water pipes 9 installed on both sides of the purification treatment box 1 and a filter component 2 slidably arranged inside the purification treatment box 1, the inner wall of the purification treatment box 1 is symmetrically provided with four slide grooves, the slide grooves extend from the middle of the water treatment box to the water outlet position, and an elastic control component 3 is arranged inside the slide groove, and the filter component 2 will squeeze the elastic control component 3 when it is blocked;

[0040] The purification treatment box 1 has openings on both sides, and two driving components 4 are symmetrically arranged. The elastic control component 3 is used to control the start and stop of the driving component 4. The driving component 4 includes a driving motor 41, a driving gear 42 and a rack 43. The rack 43 is slidably arranged on the side of the filter component 2 away from the elastic control component 3. The two driving motors 41 are installed on both sides of the purification treatment box 1 through the mounting seat component 6. The driving gear 42 is fixedly connected to the output end of the driving motor 41, located inside the opening, and is used to drive the rack 43 to move up and down;

[0041] A cleaning assembly 5 is arranged between the two symmetrically arranged racks 43 , and the cleaning assembly 5 is used for scraping and cleaning the filter assembly 2 , and the driving assembly 4 is used for driving the cleaning assembly 5 to move up and down.

[0042] In the embodiment of the application of the above technical solution, the purification treatment box 1 is used for pretreatment of sewage. The sewage is introduced into the purification treatment box 1 to pre-treat the impurities in the sewage. After the sewage containing a large amount of sludge is introduced into the purification treatment box 1, the purification treatment box 1 will not be directly filled, and there is a certain space with the top wall of the purification treatment box 1 (according to the filtering speed of the sewage, the sewage is usually controlled at two-thirds of the position of the purification treatment box 1). The impurities in the sewage are filtered and cleaned by the filter component 2. When a large amount of blockage occurs at the bottom of the filter screen 22, the incoming water flow will impact and squeeze the filter screen 22, thereby pushing the filter screen 22. When the filter screen 22 reaches a certain position, the elastic control component 3 controls the drive component 4 to start, and drives the rack 43 to move upward through the driving gear 42, thereby driving the cleaning component 5 fixedly connected between the racks 43 to move upward, and the blockage on the filter component 2 is cleaned, thereby ensuring the filtering effect.

[0043] In actual operation, it is necessary to limit the size specifications of the driving gear 42 and the rack 43 according to the size of the purification treatment box 1. At the same time, since the elastic control component 3 will only be activated when the filter component 2 is blocked to a certain extent, when the elastic control component 3 is activated, the driving gear 42 and the rack 43 must be located in a fixed position, so as to ensure that when the rack 43 moves to the open position, the driving gear 42 can be meshed and connected with the rack 43. After the driving gear 42 and the rack 43 are meshed and connected, when the driving gear 42 rotates, it will drive the cleaning component 5 fixed on the rack 43 to move up and down.

[0044] The present invention can automatically clean up according to the blockage situation, does not need manual observation and manual cleaning, reduces the use of manpower, and ensures the efficiency of sewage purification.

[0045] The preferred technical solution in this embodiment is:

[0046] Reference Figure 3-5 The filter assembly 2 includes four sliding blocks 21, a filter screen 22 and a sealing ring 23. The four sliding blocks 21 are fixedly connected to the four corners of the filter screen 22 and are slidably arranged in four slide grooves. The sealing ring 23 is fixedly connected to the filter screen 22 and is sealingly slidably arranged in the purification treatment box 1.

[0047] The interior of the purification treatment box 1 is divided into a purification space near the water inlet and a lead-out space near the water outlet by the filter screen 22. Impurities filtered by the filter screen 22 will accumulate inside the purification space, and the filtered water will be led out from the lead-out space. Since the water pipe 9 is arranged at the bottom of the purification treatment box 1, during the purification and filtering process, the waste water to be filtered is usually only in the lower half of the filter screen 22, ensuring the normal operation of the upper elastic control component 3 and the drive component 4.

[0048] When a large amount of blockage occurs at the bottom of the filter 22, the incoming water flow will impact and squeeze the filter 22, thereby pushing the filter 22. The filter 22 slides inside the purification treatment box 1 through the sliding block 21. When the filter 22 is blocked and the impact force of the water flow is greater than the elastic support force of the elastic control component 3, the filter 22 will move to a fixed position, thereby starting the driving component 4 and cleaning the filter 22 through the cleaning component 5. When the impurities on the filter 22 are cleaned, the filter 22 will be reset under the elastic support of the elastic control component 3.

[0049] Reference Figure 4-6 The elastic control component 3 includes four energized spiral tubes 31, two extrusion rods 32 and two contact rods 33. The four energized spiral tubes 31 are respectively arranged in four slide grooves, the two extrusion rods 32 are fixedly connected to the sliding block 21, and the two contact rods 33 are fixedly installed on the inner wall of one side of the slide groove close to the water outlet. The extrusion rods 32 and the contact rods 33 are both located in the upper slide groove. The extrusion rods 32 and the contact rods 33 are energized to control the drive motor 41.

[0050] An elastic waterproof wrapping layer is provided on the outside of the energized solenoid. When no power is supplied, the energized solenoid has a certain elasticity and will squeeze the filter 22 to the top of the slide slot. When the filter 22 is clogged and the pressure on the surface becomes greater and greater, the energized solenoid will be squeezed and contracted, thereby connecting the two squeezing rods 32 and the two contact rods 33. After the squeezing rods 32 and the contact rods 33 are connected, the internal sensors sense and contact each other, and the generated control signal starts to control the drive motor 41, thereby driving the cleaning component 5 to move through the drive motor 41 to clean the filter component 2.

[0051] The pressure exerted on the filter assembly 2 can be used to determine the blockage situation. When the blockage reaches a certain level, the extrusion rod 32 and the contact rod 33 come into contact, and the cleaning assembly 5 is automatically started. In this way, it can automatically determine when the interior of the purification treatment box 1 needs to be cleaned. There is no need for manual observation, which reduces manpower consumption and avoids blockage caused by not cleaning for a long time. Automatic cleaning can be performed to ensure the efficiency of the entire purification treatment.

[0052] Reference Figure 7 The cleaning assembly 5 includes two elastic shafts 51, a scraper bar 52 and a bearing bar 53. The two elastic shafts 51 are fixedly connected to both sides of the bearing bar 53 and are rotatably connected to the sides of the two racks 43. The scraper bar 52 is fixedly connected to one side of the bearing bar 53 close to the filter assembly 2.

[0053] The cross section of the support bar 53 is J-shaped, and the arc-shaped end is close to the filter assembly 2 . The cross section of the scraper bar 52 is triangular, and the tip is in contact with the filter assembly 2 .

[0054] During the filtering process, a large amount of impurities will be blocked by the filter assembly 2 and sink. The sunken impurities will fall and accumulate on the supporting bar 53. At the same time, the supporting bar 53 is set to be J-shaped, which can block the impact of the water flow to a certain extent, thereby avoiding the water flow from causing another impact on the collected sediment, ensuring the cleaning effect during cleaning.

[0055] When the rack 43 is driven by the driving gear 42, the entire cleaning assembly 5 will be driven to move upward. During the upward movement, the scraper bar 52 will scrape and clean the surface of the filter screen 22, thereby clearing the blockage on the filter screen 22. The cleared blockages will fall onto the supporting bar 53 and are finally collected and cleaned together.

[0056] Reference Figure 8 The mounting seat assembly 6 includes a control module 61, two powered spiral columns 62 and a mounting block 63. The control module 61 is fixedly connected to the side of the purification treatment box 1. The two powered spiral columns 62 are symmetrically fixedly connected to the control module 61. The mounting block 63 is fixedly connected to the other end of the other powered spiral column 62. The drive motor 41 is fixedly mounted on the upper side of the mounting block 63.

[0057] When the filter assembly 2 is squeezed and moved, the energized spiral column 62 elastically supports the mounting block 63, so that the upper drive motor 41 and the drive gear 42 are away from the opening position, and will not affect the movement of the filter assembly 2 and the rack 43;

[0058] When the contact signal of the elastic control component 3 is introduced into the control module 61, the control module 61 starts to be powered on, and the current of the control module 61 passes through the energized spiral column 62, thereby contracting the energized spiral column 62, driving the driving gear 42 to move toward the inside of the opening. The driving gear 42 will be meshed with the rack 43 during the movement, and the driving gear 42 will limit the filter component 2 to prevent the elastic control component 3 from driving the filter component 2 to move, and then the driving motor 41 controls the driving gear 42 to drive the rack 43 to move up and down, driving the cleaning component 5 below to move up;

[0059] The signal inside the control module 61 is controlled according to the cleaning time. When the cleaning is completed, the control module 61 generates a signal at a fixed time, so that the control module 61 is powered off, and the energized spiral column 62 is reset, thereby separating the drive gear 42 from the rack 43, and releasing the restriction on the elastic control component 3. At this time, the elastic control component 3 will drive the filter component 2 to reset, and the meshing connection between the drive gear 42 and the rack 43 can be controlled by powering on.

[0060] Reference Fig. 9 A mounting opening is provided on the upper side of the opening, a protective cover 10 is provided on the mounting opening, a collecting component 7 is provided in the mounting opening, and the collecting component 7 is used to collect impurities on the bearing bar 53;

[0061] The collecting assembly 7 includes a collecting box 71, two racks 72 and two push rods 73. The collecting box 71 is fixedly mounted on the top wall of the purification treatment box 1. The collecting port of the collecting box 71 is arranged on the side facing the driving motor 41. The collecting port of the collecting box 71 is inclined. The two racks 72 are symmetrically fixedly connected on both sides of the collecting box 71. The racks 72 are L-shaped and the vertical ends are arranged downward. The push rods 73 are vertically fixedly connected to the bottom ends of the racks 72 and are used to push the supporting bars 53.

[0062] Since the purification treatment box 1 will not be filled with sewage, during filtering, the sewage will not enter the collecting port of the collecting box 71 , thereby preventing the sewage from being poured into the collecting box 71 .

[0063] During the cleaning process, it is necessary to clean and collect the impurities accumulated on the supporting bar 53. When the supporting bar 53 moves upward with the rack 43, when the supporting bar 53 moves to a fixed position, the supporting bar 53 will contact the push rod 73, and the push rod 73 will be against the supporting bar 53. Due to the pressure of the push rod 73, the elastic shaft 51 will be deflected. The deflection of the elastic shaft 51 drives the supporting bar 53 to deflect. The side of the supporting bar 53 that is not connected to the scraper bar 52 begins to deflect toward the collection port of the collection box 71. The deflected supporting bar 53 transfers the internal impurities to the inside of the collection box 71. Since the collection port of the collection box 71 is tilted downward, the introduced impurities can be guided to the inside of the collection box 71 to avoid the accumulation of impurities at the collection port position, thereby ensuring the collection and cleaning of the impurities.

[0064] Regular automatic collection and cleaning can extend the detection cycle, reduce the frequency of detection, and ensure the purification effect.

[0065] Reference Fig.10 A scraping assembly 8 is provided on one side of the filter assembly 2 away from the elastic control assembly 3, and the scraping assembly 8 is used to scrape and clean the inner wall of the purification treatment box 1;

[0066] The scraping assembly 8 includes two connecting rods 81 and a scraping ring 82. The two connecting rods 81 are symmetrically fixedly connected on both sides of the filter assembly 2. The scraping ring 82 is fixedly connected to the ends of the two connecting rods 81 and contacts the inner wall of the purification treatment box 1. The cross-section of the scraping ring 82 is set to an isosceles triangle, and both sides can scrape the inner wall of the purification treatment box 1.

[0067] Since there will be a large amount of suspended matter inside the purification space, after a long time, a large amount of suspended matter will adhere to the inner wall of the purification treatment box 1 and cannot be cleaned and transferred, affecting the purification effect, it is necessary to clean these impurities adhering to the inner wall of the purification treatment box 1;

[0068] When the filter 22 moves, the connecting rod 81 and the scraper ring 82 will move with the filter 22. After the filter 22 is cleaned, the filter 22 will be reset under the elastic action of the elastic control component 3. At this time, the scraper ring 82 moving with the filter 22 will scrape and clean the inner wall of the purification treatment box 1, separating the adhesion from the purification treatment box 1, making it convenient to collect and clean the adhesion next time.

[0069] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
