Description

Technical Field

[0001] The invention relates to the technical field of industrial automation, in particular to a sewage multi-media filtering and treating device. Background Art

[0002] With the acceleration of industrialization, the problem of sewage discharge has become increasingly prominent, and the pollution and damage to the environment have become more serious. At present, although the filtration equipment widely used in the sewage treatment field can remove suspended matter, solid particles and mechanical impurities in sewage to a certain extent, there are still some technical problems that need to be solved. During the long-term operation of traditional multi-media filters, the filter layer is prone to compaction and clumping, resulting in reduced filtration efficiency and unstable effluent water quality. This is mainly because the filter layer is subjected to the dual effects of water scouring and pollutant deposition during the filtration process, which gradually reduces the gaps between the filter particles and forms a dense filter layer structure, hindering the flow of water and the effective removal of pollutants. In addition, the structural design of traditional multi-media filters is relatively simple and lacks the ability to flexibly adjust to the characteristics of different pollutants and treatment requirements.

[0003] A Chinese patent with publication number CN113816441A discloses a multi-media filter for sewage treatment. The device is provided with an oil guide device. When the rotating shaft, the first bevel gear and the second bevel gear are working, moisture and water will cause corrosion and damage to the rotating shaft and other devices. At this time, the oil guide device automatically lubricates and protects the rotating shaft and other devices when the rotating shaft and other devices are in use, which not only avoids the problem of device corrosion, but also solves the problem of rotating shaft damage, thereby ensuring the normal use of the rotating shaft and other devices; by providing a mist cooling device, when the driving motor is working continuously, the motor itself will generate heat and generate high temperature, so after long-term work, the motor will be damaged and cannot be used. At this time, the mist cooling device will perform comprehensive mist cooling on the motor when the driving motor is working, which not only avoids the problem of high temperature damaging the motor, but also solves the problem of increased filtration cost, thereby preventing the motor from being damaged by high temperature.

[0004] However, the above solution is only for protecting the driving motor and the rotating shaft in the multi-media filter to prevent the equipment from being damaged during use, but it cannot be effective for the filter layer inside the multi-media filter. When the multi-media filter layer becomes compacted and clumped, affecting the internal filtering effect, no effective action can be taken against the clumping. Moreover, when the internal filter layer accumulates more impurities with use, the filter layer cannot be quickly removed from the filter for replacement or cleaning. Summary of the Invention

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0033] Example 1

[0034] Reference Figures 1 to 3 , which is the first embodiment of the present invention, provides a sewage multi-media filtration treatment device.

[0035] Specifically, the processing assembly 100 includes a housing 101, a heating end 102 provided on the outer wall of the housing 101, and a servo motor 103 provided on the upper end of the housing 101;

[0036] The filter assembly 200 includes a bottom module 201 arranged inside the shell 101, a superimposed module 202 arranged at the upper end of the bottom module 201, a push rod 203 arranged on the inner wall of the superimposed module 202, a sealing ring 204 arranged at the upper end of the superimposed module 202, a limiting ring 205 arranged at the upper end of the sealing ring 204 and a buffer ring 206 arranged at the lower end of the bottom module 201.

[0037] Among them, the heating end 102 is installed at the outer position above the shell 101, and is partially installed inside the shell 101 to heat the sewage entering the shell 101 and pre-treat it in advance before filtering. At the same time, the servo motor 103 located at the top of the shell 101 operates together to drive the components located inside the shell 101 to operate together, and pre-treat the sewage entering the shell 101 that has not passed through the lower filter component 200. By heating and stirring, the viscosity and concentration of this part of the sewage are reduced, making it easier for this part of the sewage to pass through the lower filter component 200.

[0038] At the same time, the filter assembly 200 inside the shell 101 is composed of a bottom module 201 and a superimposed module 202, and adopts a modular design. Each filter material module is filled with filter materials of different types and particle sizes. Different filter material modules can be replaced according to the different water quality to be filtered to meet the filtration requirements of different water quality conditions. The bottom module 201 is located at the bottom position inside the shell 101, and the superimposed module 202 is fixedly installed above it. The sealing ring 204 is tightly attached to the upper surface of the top superimposed module 202. At the same time, a limiting ring 205 is fixed above the sealing ring 204. The filter unit composed of multiple filter material modules is fixed inside the shell 101 through the limiting ring 205 above the sealing ring 204 and the buffer ring 206 below the bottom module 201.

[0039] In summary, when in use, the heating end 102 outside the shell 101 can heat the sewage entering the shell 101, so that the sewage can be processed in advance before entering the filter component 200 below, and work together with the servo motor 103 at the top to process the sewage on the top of the shell 101, first reducing the viscosity and concentration of this part of the sewage to facilitate passing through the filter component 200 below.

[0040] At the same time, the filter assembly 200 below forms a filter unit through the bottom module 201 and the superimposed module 202, and adopts a modular design, which facilitates the replacement of different types of filter materials according to different filter media. At the same time, the filter unit is fixed by the limiting ring 205 and the buffer ring 206 inside the shell 101.

[0041] Example 2

[0044] Among them, the support column 1011 array is set at the outer bottom of the shell 101 to support the entire device. The water inlet 1012 set at the top transports the sewage to be filtered into the interior of the shell 101, and the filtered water is discharged through the water outlet 1013 at the bottom.

[0045] The heating end 102 is fixed to the outside of the shell 101, and the heating wire 1021 is fixed to the inside of the shell 101, located below the water inlet 1012. The heating wire 1021 heats the unfiltered sewage after entering the shell 101, facilitating subsequent filtration work.

[0050] Example 3

[0051] Reference Figures 3 to 9 , which is the third embodiment of the present invention, and is based on the previous embodiment.

[0053] Among them, the bottom module 201 serves as the bottom layer of the filter unit and is located at a lower position of the shell 101. Above the buffer ring 206, the first water outlet plate 2011 at the bottom of the bottom module 201 is relatively protruding. At the same time, a plurality of water outlet holes are opened on the surface of the first water outlet plate 2011. A fixing ring 2012 is fixedly installed below the first water outlet plate 2011, and a second inclined block 2013 is provided on the surface of the fixing ring 2012. The bottom of the rotating shaft 1031 passes through the bottom of the bottom module 201 and is located below the first water outlet plate 2011.

[0054] The transmission block 1033 outside the rotating shaft 1031 corresponds to the fixed ring 2012 at the bottom of the first water outlet plate 2011. When the rotating shaft 1031 rotates, the transmission block 1033 rotates together. Through the fit between the first inclined block 1034 on the surface of the transmission block 1033 and the second inclined block 2013 on the surface of the fixed ring 2012, the bottom module 201 is lifted upward inside the shell 101. Then, as the first inclined block 1034 and the second inclined block 2013 separate, the bottom module 201 falls back to its original position height, and this cycle repeats.

[0056] Among them, the superimposed module 202 is installed above the bottom module 201. The shape and structure of the superimposed module 202 are almost the same as those of the bottom module 201. The second water outlet plate 2021 at the bottom of the superimposed module 202 is engaged into the first concave ring 2014 above the bottom module 201, and the second concave ring 2022 above the superimposed module 202 corresponds to the second water outlet plate 2021 at the bottom of the superimposed module 202 above, so as to accumulate and stack them.

[0057] At the same time, the bottom module 201 is the same as the stacking module 202, and a placement groove 2023, a slide groove 2024 and a through groove 2025 located at the bottom of the placement groove 2023 are provided on the outer wall.

The difference is that the bottom module 201, as the bottom layer of the filter unit, is flat on the bottom surface and is not equipped with the first fixed tooth 20211 and the first push block 20212.

[0058] The outer wall of the push rod 203 is hinged with a connecting rod 2031, and the end of the connecting rod 2031 extends to the inner wall of the motion groove 2028 and slides with it.

The difference is that the overall length of the push rod 203 located in the side wall of the bottom module 201 is shorter, and there is no movable hole 2032 and ball 2033 at the bottom of the push rod 203. The internal movable rod 2035 is also shorter, and the first open loop 2036 and the second open loop 2037 are not opened.

At the same time, a second fixed tooth 2044 and a second push block 2045 are provided on the lower surface of the sealing ring 204, which are the same as the first fixed tooth 20211 and the first push block 20212 at the bottom of the stacking module 202. A second push column 2047 is also installed inside the second push block 2045. Affected by the pressing column 2041, when the pressing column 2041 is pressed downward, the inclined groove 2042 on the side wall of the pressing column 2041 will move downward, squeezing the inclined surface of the second push column 2047, so that the second push column 2047 is pushed toward the inside of the second push block 2045. When the second push column 2047 is pushed inward, the sliding column on the surface slides in the inclined groove on the surface of the second movable block 2046, pushing the second movable block 2046 downward, and the movable plate 2027 located below the second push block 2045 will be squeezed and moved downward.

[0062] A fixing groove 2051 is provided on the inner wall of the limiting ring 205, a movable groove 2052 is provided on the upper end of the fixing groove 2051, a mounting ring 2053 is provided on the lower end of the limiting ring 205, an opening 2054 is provided on the outer wall of the mounting ring 2053, a limiting column 2055 is provided on the upper end of the mounting ring 2053, and a fifth elastic member 2056 is sleeved on the outer wall of the limiting column 2055.

[0063] Among them, the limiting ring 205 is fixed inside the shell 101. When the filter unit is upward as a whole, the sealing ring 204 located above the superposition module 202 will squeeze the mounting ring 2053 to move it upward, squeeze the fifth elastic member 2056 to deform it, and the upper end of the fifth elastic member 2056 is located in the fixed groove 2051 on the surface of the limiting ring 205, and the top end of the limiting column 2055 moves inside the movable groove 2052 to prevent the mounting ring 2053 from shifting in position when moving up and down.

[0064] Preferably, a bump 2061 is provided at the end of the buffer ring 206 , a slot 2062 is provided on the inner wall of the buffer ring 206 , a sixth elastic member 2063 is provided on the inner wall of the slot 2062 , and a circular ring 2064 is fixed to the upper end of the sixth elastic member 2063 .

[0065] Among them, the bottom buffer ring 206 is fixed at the bottom position of the shell 101, located below the bottom module 201, and the upper surface of the buffer ring 206 is arrayed with multiple protrusions 2061. The sixth elastic member 2063 is placed in the groove 2062 opened between the intervals of the protrusions 2061 and is located below the circular ring 2064. When the upper bottom module 201 falls downward, the circular ring 2064 moves downward and squeezes the sixth elastic member 2063. The sixth elastic member 2063 is deformed, which plays a buffering role on the upper circular ring 2064 until the circular ring 2064 falls above the protrusion 2061.

[0066] In summary, when in use, when the upper superposition module 202 is installed above the bottom module 201, the second water outlet plate 2021 at the bottom of the superposition module 202 is engaged with the first concave ring 2014 above the bottom module 201. At this time, the first fixed tooth 20211 and the first pushing block 20212 at the bottom of the superposition module 202 are engaged with the placement groove 2023 on the upper surface of the bottom module 201. At this time, the first pushing block 20212 at the bottom of the superposition module 202 is pressed on the movable plate 2027 in the placement groove 2023 on the surface of the bottom module 201, pressing the movable plate 2027 downward. As the movable plate 2027 moves downward, the bottom of the hook 2026 in the placement groove 2023 is pressed against the bottom of the hook 2026. The end position is affected by the movement of the movable plate 2027, and rotates in the placement groove 2023. The top position of the hook 2026 engages with the first fixed tooth 20211 at the bottom of the stacking module 202, thereby fixing the stacking module 202. Similarly, when the top stacking module 202 is installed, it is fixed above the stacking module 202 below by the hook 2026. When the top sealing ring 204 is installed on the top of the stacking module 202, the second pushing block 2045 also presses down the movable plate 2027, so that the hook 2026 inside the top stacking module 202 engages and fixes the second fixed tooth 2044, thereby completing the installation of the entire filter unit.

[0067] The entire filter unit is fixed between the limiting ring 205 and the buffer ring 206. The bottom position of the rotating shaft 1031 runs through the entire filter unit and is located below the bottom module 201. The transmission block 1033 installed at the bottom of the rotating shaft 1031 cooperates with the fixing ring 2012 at the bottom of the first water outlet plate 2011. The first inclined block 1034 on the surface of the transmission block 1033 contacts the second inclined block 2013 on the surface of the fixing ring 2012. When the first inclined block 1034 rotates with the transmission block 1033, when it starts to contact the second inclined block 2013, the bottom module 201 is driven by the contact of the two inclined surfaces. Block 201 moves upward, at this time the bottom module 201 drives the entire filter unit to move upward, pushing the mounting ring 2053 to squeeze the fifth elastic member 2056, and at the same time the sixth elastic member 2063 inside the lower buffer ring 206 loses the squeezing of the entire filter unit, and the circular ring 2064 begins to push upward, and the height is only the height of the first inclined block 1034. When the two inclined surfaces lose contact, the bottom module 201 loses support and is pushed by the fifth elastic member 2056 inside the upper limit ring 205. The bottom module 201 falls downward, and the entire filter unit moves downward together, and this cycle repeats.

[0068] The rotation of the shaft 1031 drives the entire filter unit to move up and down in a small range inside the housing 101 during the filtering operation. Since the entire filter unit is fixed together, the entire filter unit swings back and forth between the limit ring 205 and the buffer ring 206. The filter material in the middle of each filter module vibrates, which affects the filter material layer that is clumped and compacted inside the filter module, reduces the compaction phenomenon inside, and reduces the impact on the filtering effect. In addition, the entire filter unit is affected by the first inclined block 1034 on the surface of the transmission block 1033 at the bottom of the shaft 1031 inside the housing 101, which drives the entire filter unit to move up. After the two inclined blocks lose contact, they are affected by the filter unit itself. The weight of the filter unit and the push of the fifth elastic member 2056 inside the upper limit ring 205 move downward, and the buffer ring 206 at the bottom prevents the filter unit from moving downward and causing damage. When the entire filter unit moves up and down inside the shell 101, in addition to vibrating the compacted blocks inside the filter module through the small vibration generated to reduce the compacted volume, when the filter unit moves up and down, inside the shell 101, the sewage at the top of the filter unit and the clean water that is about to be discharged through the bottom module 201 will also have an impact on the filter material in the filter module. Although it cannot clean up the impurities accumulated in the filter material layer, it will also make the filter material particles in the filter material layer become slightly loose, thereby reducing the compaction phenomenon in the filter layer and reducing the decline in filtration efficiency.

[0069] When the filter unit needs to be cleaned, it is only necessary to press the pressing column 2041 on the surface of the sealing ring 204. When the pressing column 2041 moves downward, the inclined groove 2042 on the side of the pressing column 2041 will squeeze the second pushing column 2047 located inside the second pushing block 2045, causing the second pushing column 2047 to move toward the inside of the second pushing block 2045. The sliding column on the surface of the second pushing column 2047 slides in the inclined groove on the surface of the second movable block 2046, causing the second movable block 2046 to move downward, pressing the movable plate 2027 below the second pushing block 2045 downward again.

[0070] When the sealing ring 204 is installed, the second pushing block 2045 presses the movable plate 2027 below downward. At this time, the end of the connecting rod 2031 on the side of the push rod 203 inside the through groove 2025 at the bottom of the placement groove 2023 moves in the motion groove 2028 on the surface of the movable plate 2027, and slides from the motion groove 2028 on the left into the inside of the limiting groove 2029 at the top of the motion groove 2028. At this time, the movable plate 2027 is restricted by the connecting rod 2031 and cannot move upward. When the movable plate 2027 moves downward, it drives the hook 2026 to engage and fix the second fixed tooth 2044. The hook 2026 is restricted by the movable plate 2027 and cannot release the restriction on the second fixed tooth 2044.

[0071] When it is necessary to release the seal, the pressing post 2041 above the sealing ring 204 is pressed, and the second movable block 2046 moves downward again, and the movable plate 2027 moves downward again for a distance. At this time, when the top of the connecting rod 2031 on the side of the push rod 203 slides upward at the bottom of the limiting groove 2029, it is affected by the limiting groove 2029 and slides along the limiting groove 2029 to the right side of the motion groove 2028. At this time, the connecting rod 2031 releases the restriction on the movable plate 2027, and the movable plate 2027 can move upward. When the movable plate 2027 moves upward, and when the movable plate 2027 moves upward, the hook 2026 on the rear side also releases the restriction on the second fixed tooth 2044. At this time, the sealing ring 204 can be removed from the superposition module 202. Similarly, when the pressing post 2041 moves downward, the bottom of the pressing post 2041 The position contacts the top of the movable rod 2035 inside the push rod 203, and the movable rod 2035 moves downward synchronously. When the movable rod 2035 moves downward, the side of the movable rod 2035 squeezes the ball 2033 in the movable hole 2032 at the bottom of the push rod 203, causing the ball 2033 to move outward. When the ball 2033 moves outward, it pushes the first push column 20214 located on the side wall of the first push block 20212, causing the first movable block 20213 inside the first push block 20212 to move downward, pushing the movable plate 2027 to move downward, thereby releasing the hook 2026 in the stacking module 202 and the bottom module 201 from fixing the first fixed tooth 20211 at the bottom of the stacking module 202. At this time, the modules in the filter unit can be removed for easy replacement.
