Description

Technical Field

[0001] This invention relates to the field of wastewater treatment, specifically to a multi-stage integrated wastewater treatment device. Background Technology

[0002] Pure water is a commonly used industrial liquid. In the electronics industry, it is used to clean circuits and wafers; in the pharmaceutical industry, it is used to clean medical equipment; and in the power industry, it is used as boiler feedwater. After use, pure water becomes industrial wastewater with a low degree of pollution. This type of industrial wastewater can generally be treated using comprehensive wastewater treatment equipment to obtain pure water that meets the requirements.

[0003] Existing equipment for purifying industrial wastewater into pure water generally includes a step of trapping small particles in the wastewater through a filter cartridge. During the wastewater treatment process, the wastewater passes through the filter cartridge from top to bottom. When the wastewater flow rate is small, this method can trap as many small particles as possible. However, when the wastewater flow rate is large, the filter cartridge cannot be fully utilized, resulting in particle accumulation in local areas of the filter cartridge, which leads to a poorer trapping effect. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-stage integrated wastewater treatment device to solve the problem that filter elements are not fully utilized when the wastewater flow rate is large.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a multi-stage integrated sewage treatment device, comprising a body, wherein a softening bottle, a carbon filter bottle and a coarse filter bottle are fixedly installed on the body, and sewage flows sequentially through the coarse filter bottle, the carbon filter bottle and the softening bottle; The filter chamber has a fixed water inlet tray with a central hole. A float ball is inserted into the central hole and floats up and down within the filter chamber, blocking the central hole. Several through holes are also formed in the water inlet tray. A connecting pipe is fixed to the bottom of the water inlet tray and connects to the through holes. Each connecting pipe has a sleeve at its bottom that abuts against it. The sleeve is fixed to the float ball by a fixing strip. The sleeve is slidably fitted onto the filter cylinder. A filter groove is provided inside the filter cylinder, and a filter element is fixed inside the filter groove. Multiple water inlet grooves are formed at the top of the filter cylinder and connect to the sleeve. A filter screen groove is formed at the top of the sleeve and connects to the connecting pipes. A fine filter screen is fixed inside the filter screen groove. The sleeve is fixed with a number of fixing plates matching the number of water inlet tanks. A plug is fixed to the bottom of the fixing plate. A vertical rod penetrating the water inlet tank is fixed to the bottom of the plug. An inclined block is fixed to the bottom of the vertical rod. A water inlet channel matching the number of water inlet tanks is opened on the side wall of the filter tank. A sealing strip is slidably installed in the water inlet channel by a spring. The sealing strip seals the water inlet channel. An inclined block is fixed inside the sealing strip. The inclined block abuts against the inclined block. The plug is the same size as the water inlet tank.

[0006] Preferably, the surfaces in contact between the inclined block one and the inclined surface block two are both designed as inclined surfaces.

[0007] Preferably, the float has a hollow structure.

[0008] Preferably, the carbon filter has a filtration chamber inside the carbon filter bottle, and an inlet is opened at the top of the filtration chamber to allow sewage to enter. A filter screen assembly is fixed inside the filtration chamber, and the filter screen assembly consists of a primary filter screen, a secondary filter screen, and an activated carbon layer from top to bottom.

[0009] Preferably, a fixing seat with the same number of sealing strips is fixed in the filter tank, and a spring rod is provided through the fixing seat. The spring rod is fixed to the sealing strip and slidably engaged with the sealing strip. The spring rod is fixed between the fixing seat and the fixing seat.

[0010] Preferably, a sliding rod is fixed to the bottom of the float ball, the sliding rod is slidably mounted on the base, the base is fixed on the fixing plate, the fixing plate is fixed in the filter chamber, and a water outlet is opened through the fixing plate with the same number of filter elements. The filter elements are fixedly connected to the water outlet pipe, and the water outlet pipe is fixedly connected to the water outlet.

[0011] Preferably, a water collection hopper is fixedly installed at the bottom of the fixed plate, and a discharge pipe that penetrates the carbon filter bottle is fixedly connected to the water collection hopper.

[0012] In summary, the present invention has the following beneficial effects: 1. The coarse filter bottle traps large particles in the wastewater, the carbon filter bottle traps small particles, and the softening bottle softens the wastewater, achieving multi-stage integrated wastewater treatment with good overall treatment effect.

[0013] 2. A central hole is drilled through the center of the water tray, and a float ball is inserted into the central hole. The float ball floats up and down in the filter chamber. The float ball blocks the central hole. Several through holes are also drilled through the water inlet tray. A connecting pipe connecting the through holes is fixed at the bottom of the water inlet tray. The bottom of each connecting pipe abuts against a sleeve. The sleeve is fixed to the float ball by fixing strips. The sleeve slides on the filter cylinder. A filter groove is set inside the filter cylinder, and a filter element is fixed in the filter groove. Multiple water inlet grooves connecting the sleeve are opened at the top of the filter cylinder. A filter screen groove connecting the connecting pipe is opened at the top of the sleeve. A fine filter screen is fixed in the filter screen groove. When the sewage flow is small, it is not enough to push the float ball. At this time, the sewage will flow into the connecting pipe from the various through holes and enter the sleeve through the fine filter screen. Then it flows to the top of the filter element through the various water inlet grooves and finally flows out from the filter element for further filtration, thereby achieving a fine filtration effect.

[0014] 3. The sleeve is fixed with the same number of fixing plates as the inlet tanks. A plug is fixed to the bottom of the fixing plate, and a vertical rod penetrating the inlet tank is fixed to the bottom of the plug. An inclined block is fixed to the bottom of the vertical rod. The filter tank sidewall has an inlet channel with the same number as the inlet tanks. A sealing strip is installed in the inlet channel by a spring and seals the inlet channel. An inclined block is fixed inside the sealing strip and abuts against the inclined block. When the sewage flow is large, the float is pushed, which drives the sleeve to descend through the fixing plates. The plug descends with the sleeve and blocks the inlet tank. The inclined block descends with the sleeve and pushes the inclined block to move outward. The inclined block pushes the sealing strip to move outward to the outside of the inlet channel. At this time, the inlet tanks are opened, and sewage flows into the filter element from the inlet channels instead of the inlet tanks. The sewage flowing into the filter element from the inlet channels will have more sufficient contact with the surface of the filter element, thereby greatly improving the sewage treatment efficiency.

[0018] Combined with appendix Figures 1-8 The aforementioned multi-stage integrated wastewater treatment equipment includes a body 11, on which a softening bottle 12, a carbon filter bottle 13, and a coarse filter bottle 14 are fixedly installed. The softening bottle 12, the carbon filter bottle 13, and the coarse filter bottle 14 constitute the multi-stage water purification system of this application. It should be noted that the wastewater first enters the coarse filter bottle 14, which is a primary filter. The coarse filter bottle 14 is filled with quartz sand within a certain particle size range. The quartz sand forms an interlocking pore structure to trap large particles in the wastewater. After being discharged from the coarse filter bottle 14, the wastewater enters the carbon filter bottle 13. The carbon filter bottle 13 is equipped with a multi-stage filtration structure to remove residual small particulate matter in the wastewater. After being discharged from the carbon filter bottle 13, the wastewater enters the softening bottle 12. The softening bottle 12 is used to soften the water. A cation exchange resin is used in the softening bottle 12 to remove magnesium and calcium ions from the wastewater, thereby reducing the water hardness. It should be noted that the softening bottle 12, carbon filter bottle 13, and coarse filter bottle 14 are connected by water pipes 16 and equipped with multiple water pumps 15 to provide power for the flow of sewage.

[0019] The carbon filter bottle 13 is provided with a filter chamber 18. The top of the filter chamber 18 has a water inlet 17, through which sewage is introduced. A filter screen assembly is fixed in the filter chamber 18. The filter screen assembly consists of a primary filter screen 19, a secondary filter screen 20 and an activated carbon layer 21 from top to bottom. It should be noted that the primary filter 19 is used for primary filtration, the secondary filter 20 is used for secondary filtration, and the activated carbon layer 21 is used to adsorb odors in wastewater.

[0020] The filter chamber 18 is also fixed with a water inlet plate 24, which is located at the bottom of the filter screen assembly. A central hole 28 is opened through the center of the water inlet plate 24, and a float ball 29 is inserted into the central hole 28. The float ball 29 floats up and down in the filter chamber 18 and blocks the central hole 28. Several through holes 26 are also opened through the water inlet plate 24. A connecting pipe 27 communicating with the through holes 26 is fixed at the bottom of the water inlet plate 24. The bottom of each connecting pipe 27 abuts against a sleeve 33. The sleeve 33 is fixed to the float ball 29 by a fixing strip 51. The sleeve 33 is slidably sleeved on the filter cylinder 38. A filter groove 41 is provided in the filter cylinder 38. A filter element 42 is fixed in the filter groove 41. Multiple water inlet grooves 39 communicating with the sleeve 33 are opened at the top of the filter cylinder 38. A filter screen groove 34 communicating with the connecting pipes 27 is opened at the top of the sleeve 33. A fine filter screen 35 is fixed in the filter screen groove 34. When the sewage flow rate is low, it is insufficient to push the float 29. At this time, the sewage will flow into the connecting pipe 27 through each of the through holes 26 and enter the sleeve 33 through the filtration of the fine filter screen 35. Then, it will flow to the top of the filter element 42 through each of the water inlet troughs 39 and finally flow out from the filter element 42 for further filtration, thereby achieving a fine filtration effect. The sleeve 33 is fixed with the same number of fixing pieces 36 as the water inlet trough 39. The bottom of the fixing piece 36 is fixed with a plug 37. The bottom of the plug 37 is fixed with a vertical rod 40 that passes through the water inlet trough 39. The bottom of the vertical rod 40 is fixed with a first inclined block 47. The side wall of the filter tank 41 is provided with water inlet channels 49 with the same number as the water inlet trough 39. A sealing strip 50 is slidably installed in the water inlet channel 49 by a spring 44. The sealing strip 50 seals the water inlet channel 49. An inclined block 48 is fixed inside the sealing strip 50. The inclined block 48 abuts against the first inclined block 47. It should be noted that the plug 37 and the water inlet 39 are the same size; When the sewage flow rate is large, the float 29 is pushed, which drives the sleeve 33 to descend through the fixing bars 51. The plug 37 descends with the sleeve 33 and blocks the inlet groove 39. The inclined block 47 descends with the sleeve 33 and pushes the inclined block 48 to move outward. The inclined block 48 pushes the sealing bar 50 to move outward to the outside of the inlet channel 49. At this time, the inlet grooves 39 are opened, and sewage flows into the filter element 42 from the inlet channels 49 instead of the inlet grooves 39. The sewage flowing into the filter element 42 from the inlet channels 49 will have more sufficient contact with the surface of the filter element 42, thereby greatly improving the sewage treatment efficiency. Specifically, the surfaces in contact with the inclined block 47 and the inclined surface block 48 are both designed with slopes, so that the descent of the inclined block 47 can push the inclined surface block 48.

[0021] It should be noted that the float 29 has a hollow structure to ensure sufficient buoyancy. Example 2:

[0022] The difference from Embodiment 1 is that, in the filter tank 41, the number of fixing seats 45 is the same as the number of sealing strips 50. A spring rod 43 is provided through the fixing seat 45. The spring rod 43 is fixed to the sealing strip 50 and slides with the sealing strip 50 (the spring rod 43 can only slide and cannot rotate). The spring 44 is fixed between the spring rod 43 and the fixing seat 45. After the float 29 floats and resets, the inclined block 47 resets, and the spring 44 resets to drive the inclined block 48 and the closing strip 50 to reset. The bottom of the float 29 is fixed with a sliding rod 31, which is slidably mounted on the base 30. The base 30 is fixed on the fixed plate 25, which is fixed inside the filter chamber 18. The fixed plate 25 has outlets 32 with the same number as the filter elements 42. The filter elements 42 are fixedly connected to the outlet pipe 46, which is fixedly connected to the outlets 32. A water collection hopper 22 is fixedly installed at the bottom of the fixed plate 25, and a discharge pipe 23 that penetrates the carbon filter bottle 13 is fixedly connected to the water collection hopper 22. Wastewater filtered by the filter element 42 will flow into the water collection hopper 22 through the water outlet pipe 46 and the water outlet 32. Wastewater flowing into the water collection hopper 22 will flow out of the carbon filter bottle 13 through the discharge pipe 23.

[0023] How to use: Wastewater is transported by each of the water pumps 15, and flows sequentially through the coarse filter bottle 14, the carbon filter bottle 13 and the softening bottle 12 to complete purification and then flows out. Wastewater enters the carbon filter bottle 13 through the inlet 17, undergoes secondary filtration through the primary filter screen 19 and the secondary filter screen 20, and is adsorbed by the activated carbon layer 21. When the sewage flow is small, the sewage will flow into the connecting pipe 27 through each of the through holes 26 and enter the sleeve 33 through the filter of the fine filter screen 35. Then it will flow to the top of the filter element 42 through each of the water inlet grooves 39 and flow out of the filter element 42 in the vertical direction. When the sewage flow rate is large, the float 29 is pushed, which drives the sleeve 33 to descend through the fixing bars 51. The plug 37 descends with the sleeve 33 and blocks the water inlet trough 39. The inclined block 47 descends with the sleeve 33 and pushes the inclined block 48 to move outward. The inclined block 48 pushes the sealing bar 50 to move outward to the outside of the water inlet channel 49. At this time, the water inlet troughs 39 are opened, and sewage will flow into the filter element 42 from the water inlet channels 49 instead of the water inlet troughs 39. Wastewater discharged from the filter element 42 flows into the water collection hopper 22 through the water outlet pipe 46 and the water outlet 32. The wastewater flowing into the water collection hopper 22 will flow out of the carbon filter bottle 13 through the discharge pipe 23.

They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
