[0003] Although the above technical solution realizes the treatment and purification of sewage through sewage sedimentation tank, sewage treatment tank and purification box, the sewage sedimentation tank relies on natural sedimentation, and its sedimentation speed is slow and inefficient, which seriously affects the efficiency of the entire purification treatment. Therefore, there is an urgent need for an efficient sewage purification treatment equipment. Summary of the invention

[0004] The present invention aims to provide a comprehensive sewage purification treatment equipment for environmental engineering, which solves the problem of low natural sedimentation efficiency of existing sewage purification treatment equipment.

[0005] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a comprehensive sewage purification and treatment equipment for environmental engineering, including a treatment box with four support columns at the bottom, a filter cartridge is arranged in the treatment box, partition plates are fixedly connected on both sides of the filter cartridge, the filter cartridge and the two partition plates divide the interior of the treatment box into a sedimentation chamber and a temporary storage chamber, a water filter hole located on one side of the sedimentation chamber is opened on the side wall of the filter cartridge, a filter membrane is arranged in the water filter hole, a filter cloth is rotatably connected to the outer wall of the filter cartridge, the length of the filter cloth is equal to the shortest length between the filter cartridge and the inner wall of the sedimentation chamber, an auxiliary moving component is arranged in the sedimentation chamber for driving the bottom of the filter cloth to move with the top of the filter cloth in the sedimentation chamber, a driving component is also arranged on the treatment box for driving the top of the filter cloth to move, the bottom of the filter cartridge is also connected to a purification bucket located at the bottom of the treatment box, a filter layer is detachably connected in the purification bucket, and a control valve is arranged at the bottom of the purification bucket.

[0006] Furthermore, the driving assembly includes a bracket, which is welded to the top of the processing box. The bracket is provided with a driving motor, and the output shaft of the driving motor is provided with a driving gear. The driving gear is meshed with a gear ring, and the gear ring is rotatably connected to the top of the filter cylinder. The top of the filter cloth is fixedly connected to the outside of the gear ring through a fixing rod.

[0007] Through the above arrangement, the driving motor and the active gear can drive the ring gear to rotate. After the ring gear rotates, the filter cloth is driven to move through the fixed rod. The filter cloth moves in the sedimentation chamber to intercept and quickly filter the sediment in the sewage. The moving speed of the filter cloth is controlled by the driving motor, thereby accelerating the separation and filtration of the sediment without affecting the sewage sedimentation, thereby improving the efficiency of sewage treatment.

[0008] Furthermore, the auxiliary moving component includes a magnet and an electromagnet, the magnet is fixedly connected to the bottom of the filter cloth, the electromagnet is slidably connected to the bottom of the sedimentation chamber, a reset spring is connected between the electromagnet and any partition plate, and a first pressure sensor and a second pressure sensor electrically connected to the electromagnet are provided on the movement trajectory of the electromagnet, and the first pressure sensor and the second pressure sensor are used to control the opening or closing of the electromagnet, and the first pressure sensor and the second pressure sensor are respectively arranged in the sedimentation chamber and the temporary storage chamber.

[0009] Through the above arrangement, the adsorption connection of the magnet and the electromagnet is used to keep the filter cloth in an unfolded state during the movement, which is beneficial to maintaining the filtering and intercepting effect of the filter cloth, and the movement of the filter cloth drives the electromagnet and the reset spring to move; when the electromagnet or the magnet generates a predetermined pressure on the first pressure sensor and the second pressure sensor, the first sensor and the second sensor are used to turn on or off the electromagnet, so that the magnet and the electromagnet are adsorbed or separated. When the magnet and the electromagnet are separated, the weight of the magnet itself can make the filter cloth across the partition plate so that the sediment on its surface can be scraped off, thereby maintaining the filtering efficiency of the filter cloth.

[0013] Through the above-mentioned arrangement, the bottom of the support plate is inflated by the action of the negative pressure blades, the air inlet pipe and the one-way valve, and the filtration efficiency is improved by inflation and pressurization. When the liquid level in the filter cartridge is below the water filter holes, air is blown into the water filter holes to keep the blocked holes unobstructed, thereby maintaining the filtration efficiency of the filter membrane.

[0014] Furthermore, a plurality of blocking rods are arranged at intervals at the bottom of the temporary storage chamber, and all the blocking rods are not in the same straight line.

[0015] Through the above arrangement, after the filter cloth drives the magnet into the temporary storage chamber, the blocked part of the filter cloth is cleared by the collision between the blocking rod and the magnet, which is beneficial to maintaining the filtering efficiency of the filter cloth.

[0016] Furthermore, a lifting rod is provided on the side wall of the temporary storage chamber, and the lifting rod is arranged between two adjacent blocking rods.

[0017] Through the above arrangement, the height of the magnet can be raised with the help of the lifting rod, thereby enhancing the impact force between the magnet and the blocking rod, which is beneficial to improving the vibration efficiency of the filter cloth, thereby maintaining the filtering effect of the filter cloth.

[0018] Compared with the prior art, this solution has the following beneficial effects:

[0019] 1. This solution realizes active filtration and adsorption of sediment in sewage in the sedimentation chamber through filter cloth, thereby solving the problem of low natural sedimentation efficiency of existing sewage purification equipment, and can improve the efficiency of purification and filtration through inflation and pressurization.

[0020] 2. This solution can perform blowing or vibration operations on the filter membrane and the filter cloth, which is beneficial to maintain the filtering effect of the filter membrane and the filter cloth, thereby ensuring the effect of this equipment.

DETAILED DESCRIPTION

[0028] The present invention is further described in detail below through specific embodiments:

[0029] Example 1

[0030] like Figures 1 to 4As shown, a comprehensive sewage purification and treatment equipment for environmental engineering includes a treatment box 2 with four support columns 1 at the bottom. A filter cartridge 3 is welded in the center of the treatment box 2, and partition plates 4 are fixedly connected to both sides of the filter cartridge 3. The filter cartridge 3 and the two partition plates 4 divide the interior of the treatment box 2 into a sedimentation chamber 5 and a temporary storage chamber 6. A water filter hole located on one side of the sedimentation chamber 5 is opened on the side wall on the lower side of the filter cartridge 3. The number of filter holes includes but is not limited to one. A filter membrane 7 is adhered to the water filter hole. A filter cloth 16 is rotatably connected to the outer wall of the filter cartridge 3. The length of the filter cloth 16 is equal to the shortest length between the outer wall of the filter cartridge 3 and the inner wall of the sedimentation chamber 5. An auxiliary moving component is provided in the sedimentation chamber 5 for driving the bottom of the filter cloth 16 to move along with the top of the filter cloth 16 in the sedimentation chamber 5. A driving component is also provided on the processing box 2 for driving the top of the filter cloth 16 to move. The bottom of the filter cylinder 3 is also connected to a purification bucket 8 located at the bottom of the processing box 2. The bottom of the purification bucket 8 is located above the support column 1. A filter layer 9 is removably connected in the purification bucket 8. The filter layer 9 of this embodiment is made of activated carbon. A control valve 10 is provided at the bottom of the purification bucket 8.

[0031] In this embodiment, the driving assembly includes a bracket 11, which is welded to the top of the processing box 2. A driving motor 12 is bolted to the bracket 11, and the output shaft of the driving motor 12 passes through the bracket 11; a driving gear 13 located below the bracket 11 is provided on the output shaft of the driving motor 12, and a ring gear 14 is meshed on the driving gear 13, and the ring gear 14 is rotatably connected to the top of the filter cylinder 3, and a fixing rod 15 located above the partition plate 4 is adhered to the top of the filter cloth 16, and the fixing rod 15 is fixedly connected to the outer side of the ring gear 14.

[0032] In this embodiment, the auxiliary moving assembly includes a magnet 17 and an electromagnet 18, and the magnet 17 is fixedly connected to the bottom of the filter cloth 16. A chute 19 is provided in the sedimentation chamber 5, and the electromagnet 18 is slidably connected in the chute 19. A guide rod 20 passing through the electromagnet 18 is also provided in the chute 19, and a through hole is provided on the electromagnet 18 for the guide rod 20 to pass through. A reset spring 21 is connected between the electromagnet 18 and the partition plate 4, and a first pressure sensor 22 and a second pressure sensor 23 electrically connected to the electromagnet 18 are provided on the movement trajectory of the electromagnet 18. The first pressure sensor 22 and the second pressure sensor 23 are used to control the opening or closing of the electromagnet 18, and the first pressure sensor 22 and the second pressure sensor 23 are respectively arranged in the sedimentation chamber 5 and the temporary storage chamber 6.

[0033] In this embodiment, a plurality of spaced blocking rods 24 are provided at the bottom of the temporary storage chamber 6, each of which is located on the movement trajectory of the magnet 17, and all the blocking rods 24 are not on the same straight line. Two spaced lifting rods 25 are provided on the side wall of the temporary storage chamber 6, and each lifting rod 25 is distributed between two adjacent blocking rods 24.

[0034] The working process of this embodiment:

[0035] When filtering and purifying sewage, firstly, the sewage is injected into the sedimentation chamber 5, and then the electromagnet 18 and the driving motor 12 are started. After the electromagnet 18 is energized, it can generate suction with the magnet 17 at the bottom of the filter cloth 16 and adsorb together. After the driving motor 12 is started, the fixed rod 15 is driven to rotate through the driving gear 13 and the ring gear 14. After the fixed rod 15 rotates, it drives the filter cloth 16 and the magnet 17 to rotate together. With the help of the filter cloth 16, the active adsorption and filtration of the sediment in the sewage are realized. At the same time, the magnet 17 can also adsorb some magnetic substances in the sewage, which is conducive to improving the purification and treatment efficiency of the sewage. For the area where the filter cloth 16 does not pass, the sewage will be naturally precipitated, so that the sediment in the sewage is naturally precipitated and falls into the bottom of the sedimentation chamber 5. In this embodiment, the driving motor 12 is used to control the rotation speed of the driving gear 13 and the ring gear 14, so that the filter cloth 16 can move in the sedimentation chamber 5 at a slower speed, thereby reducing the influence of the filter cloth 16 on the natural sedimentation of sewage during the movement.

[0036] When the electromagnet 18 moves to the first pressure sensor 22 and generates moving pressure on it, the first pressure sensor 22 cuts off the power to the electromagnet 18, and the electromagnet 18 loses its adsorption ability with the magnet 17. The electromagnet 18 is reset under the action of the reset spring 21, and the magnet 17 continues to move with the filter cloth 16. When the filter cloth 16 contacts the partition plate 4, the filter cloth 16 will slide against the partition plate 4, so that the partition plate 4 can scrape off the sediment or adsorbed matter on the surface of the filter cloth 16 and the magnet 17, and this part slides along the partition plate 4 into the sedimentation chamber 5.

[0037] When the magnet 17 and the filter cloth 16 pass over the partition plate 4, since the fixed rod 15 and the magnet 17 are in an inclined state, the magnet 17 will quickly move to the bottom of the fixed rod 15 after passing over the partition plate 4, driven by the filter cloth 16, so that the blocking rod 24 collides with the magnet 17, so that the sediment on the filter cloth 16 further falls off, which is conducive to keeping the filter cloth 16 from being blocked. After the filter cloth 16 drives the magnet 17 to pass over the blocking rod 24, the magnet 17 can be lifted to a predetermined height by the lifting rod 25, so that the sediment attached to the surface of the filter cloth 16 can be shaken off by the collision between the magnet 17 and the next blocking rod 24. When the magnet 17 collides with the blocking rod 24, the impact force generated by the collision can also produce a certain vibration effect on the filter membrane 7, which can prevent the filter membrane 7 from vibrating.

[0038] When the magnet 17 generates a predetermined pressure on the second pressure sensor 23, the electromagnet 18 is energized through the second pressure sensor 23. When the filter cloth 16 and the electromagnet 18 pass over another partition plate 4, they will again scrape off some of the attachments on the surface of the filter cloth 16 and the magnet 17, which is conducive to maintaining the adsorption and filtration capabilities of the magnet 17 and the filter cloth 16. After the magnet 17 passes over the partition plate 4, the magnet 17 will fall into the sewage in the sedimentation chamber 5 under the action of its own gravity and be adsorbed together with the electromagnet 18, so that the filter cloth 16 is unfolded again.

[0039] Example 2

[0040] like Figure 5 As shown, Figure 5 The cutting position and Figure 4 The cutting position is the same, and the difference between this embodiment and embodiment 1 is only that: a support plate 26 is welded inside the filter cartridge 3, the support plate 26 is provided with an air inlet hole, the air inlet hole is connected to an air inlet pipe 27, a one-way valve 28 is installed on the air inlet pipe 27, and a plurality of negative pressure blades 29 located below the driving gear 13 are provided on the output shaft of the drive motor 12.

[0041] The difference between the working process of this embodiment and the working process of embodiment 1 is that after the drive motor 12 is started, the drive motor 12 can drive the negative pressure blade 29 to rotate, so that the air inlet pipe 27 is inflated by the negative pressure blade 29. Due to the action of the one-way valve 28, the gas will be continuously infused into the filter cartridge 3 below the support plate 26. With the injection of air, the pressure inside it increases, which is conducive to the rapid filtration of sewage in the filter cartridge 3 by pressurization. At the same time, when the liquid level of sewage in the filter cartridge 3 is below the filter membrane 7, the filter membrane 7 can be cleared by blowing air, which is conducive to maintaining the filtering effect of the filter membrane 7.

[0042] The above are only embodiments of the present invention, and the common knowledge such as the known specific structures and / or characteristics in the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
