Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to an environmentally friendly wastewater treatment device. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, and energy, and is increasingly becoming a part of everyday life for ordinary people. An environmentally friendly wastewater treatment device, disclosed in CN118495726A, includes a main body with a sludge tank at its top. A drive assembly is located on the right side of the top of the main body. It also includes an anti-corrosion device, located on top of the sludge tank. The anti-corrosion device comprises an electric push rod, a cover plate, and a non-Newtonian liquid bladder. The bottom of the electric push rod is fixedly installed at the top edge of the sludge tank, and the bottom edge of the cover plate is fixedly installed at the top of the telescopic end of the electric push rod. The right side of the non-Newtonian liquid bladder is fixedly installed between the left side of the outer wall of the electric push rod and the left side of the telescopic end of the electric push rod. The anti-corrosion device also includes a transmission rod, a meniscus, a connecting scraper, and an anti-corrosion arc bladder. This invention allows the electric push rod to actuate the cover plate, unlike traditional cleaning methods that require manual opening of the cover plate, increasing preparation time and avoiding the risk of injury to cleaning personnel due to falling debris.

[0003] The above-mentioned technical solutions can effectively scrape off sludge and screen it through vibrating screens, but ensuring the quality of impurity collection in sewage affects the final sewage treatment effect. In sewage treatment, how to effectively crush larger particles of impurities to improve the effect of subsequent recycling and reuse, and how to fully ensure the effect of sewage purification are all difficult problems in this field. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an environmentally friendly wastewater treatment device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An environmentally friendly wastewater treatment device includes: a mixing tank assembly, a chemical supply tank assembly, a screw conveyor assembly, a crushing tank assembly, a filter tank assembly, a sedimentation and discharge assembly, and a drive motor assembly;

[0007] The pulverizing box assembly is disposed through the upper end of the filter box assembly. The pulverizing box assembly contains a box body, a feeding inclined plate, a linkage double gear assembly, and two pulverizing rollers. The two pulverizing rollers are rotatably sleeved inside the box body and abut against each other. One end of each of the two pulverizing rollers extends to one side of the box body. The linkage double gear assembly is installed at one end of the two pulverizing rollers. The lower end of the inclined tube penetrates through the upper end of the box body, and the end of the inclined tube extending into the box body is located between the feeding inclined plates.

[0008] Compared with existing technologies, this application can provide power to multiple components within the device through a single power source, thereby effectively realizing the entry of sewage and the addition and mixing of reagents; it can also achieve the crushing and filtration of pollutants and flocculated impurities in sewage, thus significantly improving the quality of sewage treatment; and it can further improve the quality of sewage during discharge through processes such as sedimentation.

[0009] Preferably, the mixing chamber assembly includes a mixing chamber, a driving chamber, a vertical shaft, a stirring component, and a universal drive assembly. The driving chamber is located at the lower end of the mixing chamber, the universal drive assembly is located inside the driving chamber, and the vertical shaft and the stirring component are rotatably sleeved at the bottom of the mixing chamber from left to right.

[0010] The drug supply box assembly is fixed to one side of the mixing box assembly, and the drug supply box assembly is provided with a feeding pipe, which is installed through one side of the mixing chamber.

[0011] The sedimentation discharge assembly is fixed to one side of the lower end of the mixing tank assembly;

[0012] The spiral lifting assembly is disposed through the connection end of the mixing tank assembly and the sedimentation discharge assembly. The spiral lifting assembly is provided with an arc-shaped lifting pipe, a filter screen and an inclined pipe. The filter screen is disposed at the lower end of the arc-shaped lifting pipe and extends into the sedimentation discharge assembly.

[0013] The filter box assembly is disposed through the upper end of the sedimentation discharge assembly;

[0014] The drive motor assembly is mounted on one side of the housing component, and the drive motor assembly is connected to one of the crushing roller components.

[0015] Furthermore, the mixing tank assembly, the chemical supply tank assembly, the spiral lifting assembly, the filter tank assembly, the sedimentation and discharge assembly, and the drive motor assembly can work together with the pulverizing tank assembly to achieve the mixing of wastewater and chemicals, and also to lift impurity particles for pulverization and filtration.

[0016] Preferably, a sewage hopper is fixed at the top of the mixing chamber, a sleeve is provided through the middle of the sewage hopper, a synchronous belt assembly is installed between the vertical shaft and the stirring component, a linkage shaft is installed at the upper end of the vertical shaft, the linkage shaft extends into the sleeve, a scraper is fixed on one side of the linkage shaft, and the scraper abuts against the side wall inside the sleeve.

[0017] A sealing rod is connected to the vertical shaft, and a tube is slidably sleeved on one side of the sealing rod. The tube is fixed to one end of the side wall inside the mixing chamber, and one end of the sealing rod can extend to the end of the feed pipe located inside the mixing chamber.

[0018] The vertical shaft component includes an upper vertical shaft component and a lower vertical shaft component arranged from top to bottom. A U-shaped shaft component is fixed to one end of the upper vertical shaft component and the lower vertical shaft component. A linkage frame assembly is provided through the U-shaped shaft component. One end of the linkage frame assembly is fixedly connected to the sealing rod component.

[0019] A partition assembly is fixed inside the mixing chamber, and the stirring element is located between the partition assemblies.

[0020] Furthermore, the baffle assembly consists of two plate components. One plate component is narrower and fixed at the top of the mixing chamber, while the other plate component is fixed at the bottom of the mixing chamber and is taller, forming a sedimentation tank structure. This provides ample space for mixing wastewater and chemicals. Simultaneously, an external power mechanism drives the vertical shaft, linkage shaft, synchronous belt assembly, and agitator to rotate synchronously. The linkage shaft drives the scraper to scrape the inner wall of the casing. The synchronous belt assembly can employ a toothed belt and toothed pulley. This ensures stable power transmission. The U-shaped shaft ensures that the upper and lower vertical shafts rotate coaxially. The coaxial rotation of the upper and lower vertical shafts drives the U-shaped shaft to rotate. The U-shaped shaft abuts against the side wall inside the linkage frame assembly, causing the linkage frame assembly to move smoothly back and forth under its action. This back and forth movement controls the lower end of the corresponding feed pipe. This back and forth movement enables the sealed insertion into the feed pipe and then removal from the feed pipe, resulting in the addition of the agent. This facilitates intermittent agent addition and fully ensures the effect of the addition.

[0021] Preferably, the drug supply box assembly includes a supply box body and a drug inlet pipe. The supply box body is fixed to one side of the mixing box assembly, and the drug inlet pipe is installed through the upper end of the supply box body. The upper end of the supply pipe is installed through the lower end of the supply box body.

[0022] Furthermore, a pump supply device can be installed inside the feeding tank to pressurize and transport the wastewater treatment agents inside the feeding tank to the mixing chamber through the feeding pipe. The wastewater treatment agents inside the feeding tank can be added according to the wastewater conditions to effectively treat the wastewater. The agents used are existing wastewater treatment agents, such as flocculants, pH adjusters, disinfectants, etc., or a mixture of one or more.

[0023] Preferably, the upper end of the inclined tube is disposed through one side of the upper end of the arc-shaped lifting tube. The arc-shaped lifting tube and the inclined tube are arranged in an inverted V shape. An auger shaft is rotatably sleeved inside the arc-shaped lifting tube. The lower end of the auger shaft and the lower end of the vertical shaft both extend into the drive cavity. The lower end of the auger shaft and the lower end of the vertical shaft are connected to the universal transmission assembly.

[0024] An opening is provided on one side of the arc-shaped lifting pipe extending to the bottom of the mixing chamber, and an arc-shaped opening is provided on the lower end of the arc-shaped lifting pipe extending into the sedimentation discharge assembly. The opening and the arc-shaped opening are located on both sides of the lower end of the arc-shaped lifting pipe, and the filter screen is fixed inside the arc-shaped opening. The auger shaft and the filter screen abut against each other.

[0025] Furthermore, the arc-shaped lifting pipe fitting is a component that combines a square tube structure and an arc-shaped tube structure. The arc-shaped tube structure is located near one end of the sedimentation and discharge assembly and can be installed throughout the sedimentation and discharge assembly. It also facilitates the cooperation between the auger shaft and the arc-shaped interior. The lower end of the arc-shaped tube is open, allowing sewage to enter the arc-shaped lifting pipe fitting through the inlet and then pass through the filter screen into the sedimentation and discharge assembly. At the same time, some dirt, impurities, and solid particles will also enter the arc-shaped lifting pipe fitting. The rotation of the auger shaft can lift the dirt particles, making it easier for them to enter the crushing box assembly through the inclined pipe fitting. A screen component can also be installed on the auger shaft to retain impurities and allow sewage to fall.

[0026] Preferably, the sedimentation discharge assembly includes a sedimentation tank and a sedimentation baffle assembly, the sedimentation baffle assembly being installed inside the sedimentation tank, and the filter screen being located on one side of the sedimentation baffle assembly.

[0027] Furthermore, a discharge pipe and corresponding electronically controlled valve components are installed through the end of the sedimentation discharge component away from the mixing tank component. Meanwhile, the sedimentation baffle assembly consists of three plate components. The two plate components on both sides are sealed and fixed to the bottom of the sedimentation tank, and the plate component in the middle is sealed and fixed to the top of the sedimentation tank, which can realize sedimentation and discharge.

[0028] Preferably, the filter box assembly includes a purification box, an electric telescopic rod is fixed to the upper end of the purification box, a connecting plate is fixed to the piston rod end of the electric telescopic rod, a sealing plate is fixed to the lower end of the connecting plate, and a purification component is installed together with the sealing plate and the purification box.

[0029] Furthermore, the purification components effectively allow wastewater to enter, filtering the wastewater and debris that rises into the crushing chamber, facilitating the wastewater's descent and full entry into the sedimentation discharge components for sedimentation.

[0030] Preferably, the purification component includes multiple square frames arranged at equal intervals from front to back, with a sliding plate assembly slidably mounted on the upper ends of two adjacent square frames, and two adjacent sliding plate assemblies respectively arranged on both sides of the same square frame, with a square frame located at the rear end fixedly connected to a sealing plate.

[0031] Two adjacent square frame pieces abut against each other, and through holes are provided on both sides of the upper end of the through hole. The two through holes on the two adjacent square frame pieces are arranged in a circular shape. Two purification screens are fixed inside the square frame piece, and the two purification screens in the same square frame piece are located between the two through holes on the square frame piece.

[0032] The bottom of the square frame is provided with multiple drainage holes at equal intervals, and the multiple drainage holes in the same square frame are all located between two purification screens in the square frame.

[0033] The frontmost square frame abuts against the side wall inside the purification chamber, and multiple square frames are sealed and installed inside the purification chamber.

[0034] Furthermore, the purification component consists of multiple parts. Each individual component within the purification component can be understood as a square frame structure, with two filter screens fixed inside the frame. The upper ends of two adjacent individual components that abut each other allow sewage to enter and pass through the filter screens into the frame. The sewage is then discharged through the holes at the bottom of the frame. Impurities remain between the two adjacent filter screens in the two adjacent frames and are cleaned regularly to collect and recycle dirt and impurity particles for subsequent reuse.

[0035] Preferably, a through-hole is provided on one end sidewall of the mixing chamber, and a sealing baffle is hinged to one side of the mixing box assembly, with the sealing baffle located on one side of the through-hole.

[0036] Furthermore, the sealing baffle and through-hole effectively ensure the sealing of the mixing chamber, while also facilitating the cleaning of the inside of the mixing chamber.

[0037] Preferably, the drive motor assembly includes a motor assembly, the output shaft of the motor assembly is fixedly connected to one of the crushing rollers, a rotating shaft is rotatably sleeved on one side of the mixing box assembly, a double bevel gear linkage assembly is mounted on the rotating shaft and the vertical shaft, and a timing belt assembly is mounted on one end of the rotating shaft extending out of the mixing box assembly and the output shaft of the motor assembly.

[0038] Furthermore, it can fully ensure that sewage enters the arc-shaped lifting pipe fitting and passes through the filter screen into the sedimentation and discharge component. Moreover, some pollutant particles and particles generated by flocculation reaction will be intercepted by the filter screen, lifted by the auger shaft, and then enter the crushing box component through the inclined pipe fitting for crushing.

[0039] The beneficial effects of the present invention are:

[0040] 1. This application achieves the goal of providing power to multiple components from a single power source through the ingenious combination of a single power source and corresponding components, thereby enabling the components to operate quickly and stably, reducing energy consumption and production costs; the vertical shaft can be rotated through the action of the synchronous belt assembly II, the rotating shaft and the double bevel gear linkage assembly, and the stirring component and the auger shaft can be rotated through the synchronous belt assembly I and the universal transmission assembly, thereby achieving stable power transmission;

[0041] 2. The vertical shaft, synchronous belt assembly, and agitator work together to mix the wastewater and chemicals thoroughly, which helps the chemicals to work effectively and improves the treatment effect on the wastewater.

[0042] 3. The filter screen can block dirt particles and flocculated particles after the reaction of the agent, so that the impurities can be lifted by the auger shaft for subsequent crushing and other treatments. At the same time, the baffle assembly can intercept sewage, which helps to mix sewage and agents. In actual preparation, a pipe component can be set at the lower end of the baffle assembly, which directly passes through the arc-shaped lifting pipe, so that some settled dirt particles can be transported into the arc-shaped lifting pipe and are also easy to lift.

[0043] 4. The U-shaped shaft can drive the linkage frame assembly to reciprocate, which facilitates reciprocating movement and allows the front end to be inserted into the feed tube. When inserted, it can block the addition of medicine and prevent the addition of medicine. When removed from the feed tube, medicine can be added, realizing intermittent medicine addition.

[0044] 5. The linkage of the double gear assembly enables the two crushing rollers to rotate in opposite directions, and the feed inclined plate allows impurities removed from the inclined tube to enter between the two crushing rollers, where they are effectively crushed, facilitating subsequent centralized filtration and collection.

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0054] The term "embodiment" as used herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of the phrase "embodiment" in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0055] Reference Figures 1-7 An environmentally friendly wastewater treatment device includes a mixing chamber assembly 1, which has a mixing chamber 11, a drive chamber, a vertical shaft 16, a stirring element 19, and a universal drive assembly 18. The drive chamber is located at the lower end of the mixing chamber 11, and the universal drive assembly 18 is located inside the drive chamber. The vertical shaft 16 and the stirring element 19 are rotatably sleeved on the bottom of the mixing chamber 11 from left to right. In actual production, the bottom of the mixing chamber 11 is inclined, which allows the wastewater to flow automatically downwards. The vertical shaft 16 can be connected to an external power assembly for operation and transmission, enabling the stirring element 19 and the universal drive assembly 18 to move.

[0056] In the technical solution of this application embodiment, the universal transmission assembly 18 consists of a telescopic rod assembly in the middle and two universal transmission components installed at both ends of the rod assembly. The two universal transmission components are connected to the vertical shaft 16 and the end of the auger shaft 34 extending into the drive cavity. By setting the drive cavity, the universal transmission assembly 18 can be prevented from contacting sewage, thus extending its service life. In addition, the vertical shaft 16 and the agitator 19 are also linked to ensure that the agitator 19 can rotate, which facilitates the mixing of sewage and chemicals.

[0057] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 A sewage hopper 13 is fixed at the top of the mixing chamber 11. A sleeve 12 is installed through the middle of the sewage hopper 13. A synchronous belt assembly 17 is installed between the vertical shaft 16 and the agitator 19. The synchronous belt assembly 17 can transmit power, so that the agitator 19 can rotate with the vertical shaft 16. The rotation of the agitator 19 helps to mix the agent and sewage. A linkage shaft 15 is installed at the upper end of the vertical shaft 16. The linkage shaft 15 extends into the sleeve 12. A scraper 14 is fixed on one side of the linkage shaft 15. The scraper 14 abuts against the inner wall of the sleeve 12. The vertical shaft 16 can drive the linkage shaft 15 to rotate, so that the scraper 14 can rotate against the inner wall of the sleeve 12, avoiding impurities from adhering to the inner wall of the sleeve 12.

[0058] In some embodiments, the operator can provide a synchronous belt assembly 17 structure, which can be driven by a combination of pulleys and belts, and can also be provided with a toothed structure; the position where the scraper 14 and the sleeve 12 abut against each other can be made of rubber material, which can achieve squeezing and scraping, and when encountering objects with strong adhesion, it can deform to allow the objects to pass through, avoiding the situation where the abutment affects the operation of the components and causes damage to the components.

[0059] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 A sealing rod 112 is connected to the vertical shaft 16. A tube 111 is slidably sleeved on one side of the sealing rod 112. The tube 111 is fixed on one end side wall inside the mixing chamber 11. One end of the sealing rod 112 can extend to the end of the feed pipe 23 located inside the mixing chamber 11.

[0060] The tube body 111 can be fixed to one end of the side wall inside the mixing chamber 11, and the sealing rod 112 is slidably installed inside it. Through the action of the linkage frame assembly 163, the sealing rod 112 can move back and forth. Through the back and forth movement of the sealing rod 112, the sealing rod 112 can gradually move towards the feed pipe 23 and insert into the feed pipe 23 to block the addition of the medicine when it moves away from the tube body 111. When the sealing rod 112 moves towards the tube body 111, one end of the sealing rod 112 gradually moves out of the feed pipe 23 and separates, allowing the medicine to enter the mixing chamber 11. This process can achieve the effect of adding medicine intermittently, avoiding the situation of excessive medicine caused by continuous administration.

[0061] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 A partition assembly 110 is fixed inside the mixing chamber 11. The stirring element 19 is located between the partition assemblies 110. The partition assembly 110 consists of two plates. A narrow plate is fixed to the bottom of one side inside the mixing chamber 11, and a taller plate is fixed to the bottom inside the mixing chamber 11. The upper end of the taller plate is higher than the lower end of the narrower plate so as to form a storage structure. This facilitates the stirring element 19 to stir the sewage and the agent, which helps to mix them so that the agent and sewage can combine and purify the sewage.

[0062] The high plate in the partition assembly 110 can act as a barrier to prevent some impurities from continuing to move. Pipes can also be installed on the high plate in the partition assembly 110 to facilitate the direct transport of impurities into the arc-shaped lifting pipe 31 for easy lifting.

[0063] Reference Figure 1 , Figure 2 A through-hole is provided on one side wall of the mixing chamber 11. A sealing baffle is hinged to one side of the mixing box assembly 1. The sealing baffle is located on one side of the through-hole and can be opened periodically as needed. Before opening, the addition of sewage must be stopped and the equipment must be kept running. When opening the sealing baffle, attention should be paid to the impact of sewage flowing out and care should be taken to protect the staff. After the sewage flows out, it is convenient to clean the mixing chamber 11 and to collect the impurities for further treatment.

[0064] Reference Figure 3, Figure 5 The vertical shaft component 16 includes an upper vertical shaft component 161 and a lower vertical shaft component 162 arranged from top to bottom. A U-shaped shaft component 164 is fixed to one end of the upper vertical shaft component 161 and the lower vertical shaft component 162. A linkage frame assembly 163 is provided through the U-shaped shaft component 164. One end of the linkage frame assembly 163 is fixedly connected to the sealing rod component 112.

[0065] In the technical solution of this application embodiment, the U-shaped shaft 164 ensures that the upper vertical shaft 161 and the lower vertical shaft 162 rotate coaxially. The coaxial rotation of the upper vertical shaft 161 and the lower vertical shaft 162 drives the U-shaped shaft 164 to rotate. The U-shaped shaft 164 abuts against the side wall inside the linkage frame assembly 163, causing the linkage frame assembly 163 to move smoothly back and forth under the action of the sealing rod 112. The reciprocating movement of the sealing rod 112 controls the lower end of the sealing rod 112 corresponding to the feeding pipe 23. The reciprocating movement of the sealing rod 112 enables the sealing insertion into the feeding pipe 23 and then removal from the feeding pipe 23, resulting in the addition of the agent. This facilitates the intermittent addition of the agent and fully ensures the effect of the addition.

[0066] Reference Figure 1 , Figure 2 , Figure 3 The chemical supply tank assembly 2 is fixed to one side of the mixing tank assembly 1. The chemical supply tank assembly 2 is equipped with a feeding pipe 23, which passes through one side of the mixing chamber 11. The chemical supply tank assembly 2 is equipped with a feeding box body 22 and a chemical inlet pipe 21. The feeding box body 22 is fixed to one side of the mixing tank assembly 1. The chemical inlet pipe 21 passes through the upper end of the feeding box body 22, and the upper end of the feeding pipe 23 passes through the lower end of the feeding box body 22. A pressurizing component can be installed in the feeding box body 22 to allow the high-pressure chemical in the feeding box body 22 to enter the feeding pipe 23 and then enter the mixing chamber 11, which helps to mix the chemical and sewage. The chemical can be added through the chemical inlet pipe 21. It also has a sealing component to prevent high-pressure leakage and ensure that the high-pressure chemical enters the mixing chamber 11. Moreover, the chemical can be one or more of the existing sewage treatment chemicals.

[0067] Reference Figure 1 , Figure 2 The sedimentation discharge component 6 is fixed to one side of the lower end of the mixing box component 1. The sedimentation discharge component 6 includes a sedimentation box 61 and a sedimentation baffle assembly 62. The sedimentation baffle assembly 62 is installed inside the sedimentation box 61, and the filter screen 33 is located on one side of the sedimentation baffle assembly 62. The sedimentation baffle assembly 62 can divide the internal space of the sedimentation box 61, which facilitates sedimentation operations and allows impurities to be deposited at the front end of the two plates fixed at the lower end.

[0068] Alternatively, a maintenance and cleaning door assembly can be installed on one side of the sedimentation baffle assembly 62 to facilitate cleaning of the sedimentation baffle assembly 62. At the same time, a drain pipe is installed in the sedimentation tank 61, which is located at the rear end of the sedimentation baffle assembly 62, and can effectively discharge the purified and settled wastewater.

[0069] Reference Figure 1 , Figure 2 , Figure 3 The spiral lifting component 3 is installed at the connection end between the mixing box component 1 and the sedimentation discharge component 6. The spiral lifting component 3 is equipped with an arc-shaped lifting pipe 31, a filter screen 33 and an inclined pipe 32. The filter screen 33 is located at the lower end of the arc-shaped lifting pipe 31 and extends into the sedimentation discharge component 6. It can filter sewage and lift particulate impurities for subsequent treatment of particulate impurities.

[0070] Reference Figure 1 , Figure 2 , Figure 3 The upper end of the inclined tube 32 is disposed through one side of the upper end of the arc-shaped lifting tube 31. The arc-shaped lifting tube 31 and the inclined tube 32 are arranged in an inverted V shape, which can lift the dirt particles and make the dirt particles move into the crushing box assembly 4 through the inclined tube 32, so as to facilitate the crushing operation of the dirt particles. The auger shaft 34 is rotatably sleeved inside the arc-shaped lifting tube 31. The lower end of the auger shaft 34 and the lower end of the vertical shaft 16 both extend into the drive cavity. The lower ends of the auger shaft 34 and the lower ends of the vertical shaft 16 are connected to the universal transmission assembly 18, which can ensure the quality of linkage, so that the auger shaft 34 can rotate with the vertical shaft 16 under the action of the universal transmission assembly 18, which facilitates the lifting of dirt particles.
