Description

Technical Field

[0001] This invention relates to the technical field of water supply and drainage, and more particularly to an automatic water supply and drainage device. Background Technology

[0002] Water supply and drainage is a general term for facilities that provide water and wastewater for people's lives, production, municipal services, and fire protection. It supplies water in quantities and qualities that meet the different needs of various users, while also collecting, transporting, and treating wastewater to eliminate pollutants in the wastewater that could harm human health and protect the environment.

[0003] For example, in patent document with patent application number 202121968393.7, the water supply and drainage device includes a drainage tank. Four support columns are installed at the lower end of the drainage tank, and the four support columns are arranged in a circular array. A stirring mechanism is installed in the middle of the lower end of the drainage tank, and the stirring mechanism extends into the drainage tank. A drain port is opened at the lower left part of the outer cylindrical surface of the drainage tank. A drain pipe is installed in the inner cavity of the drain port, and the inner cavity of the drain pipe communicates with the inner cavity of the drainage tank. A filter mechanism is installed on the upper inner wall and the right inner wall of the drainage tank. A water inlet pipe is installed at the upper left part of the outer cylindrical surface of the drainage tank, and the water inlet pipe extends into the drainage tank. A dosing mechanism is installed at the upper end of the drainage tank. This device can prevent large particles from adhering to the filter screen by setting the filter mechanism, and can scrape off the sediment adhering to the bottom wall of the drainage tank by setting the stirring mechanism.

[0004] Regarding the aforementioned technologies, although the device can perform cleaning, the cleaning process requires the machine to be stopped. During use, as the water flows, most of the debris accumulates on the filter screen, affecting the filtration speed and reducing the filtration efficiency. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an automatic water supply and drainage device, which solves the technical problem that although the prior art can perform cleaning, the cleaning process requires the machine to be stopped. During use, as the water flows, most of the debris will accumulate at the filter screen, affecting the filtration speed and reducing the filtration efficiency.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0009] This invention provides an automatic water supply and drainage device, including a cavity, a turntable, a filter module, and a drive component. The cavity forms a hollow space, which is divided into a first chamber and a second chamber by a partition. The cavity has an inlet and an outlet communicating with the first chamber. The turntable is rotatably connected to the cavity around a vertical axis, and the drive component is connected to the turntable to drive its rotation. The turntable has several through slots, and the filter module is detachably disposed within one of these slots. Wastewater can enter the first chamber through the inlet, flow through the filter module, and exit through the outlet.

[0010] The cavity is also equipped with an air inlet and an air outlet that communicate with the second chamber. Airflow can enter the second chamber from the air inlet, flow through the filter module, and then be output from the air outlet.

[0011] The liquid inlet and the air outlet are located on the same side of the turntable, while the liquid outlet and the air inlet are located on the same side of the turntable and opposite to the liquid inlet.

[0012] In this technical solution, the automatic water supply and drainage device includes a cavity, a turntable, and a filter module. The filter module plays a filtering role for sewage. It is set on the turntable. During the use of the device, sewage enters the cavity through the inlet and enters the first chamber. Under pressure, it flows through the filter module to achieve the filtering action and is then output from the outlet. In the whole process, the filter module can achieve the filtration treatment of sewage.

[0013] Furthermore, the turntable is designed to operate via a drive mechanism, which allows different filtration modules to participate in the wastewater filtration process, thereby improving the wastewater filtration efficiency.

[0014] The driving component can be a stepper motor. When the device is in use, the driving component can be configured to drive the turntable to rotate intermittently, that is, after a filter module is in the first chamber or the second chamber for a period of time, the turntable is driven to rotate by an angle.

[0015] Specifically, taking a turntable with 6 filter modules symmetrically arranged in the center as an example, the turntable can be set to operate by pausing for 5-10 seconds after rotating 30°, and then rotating in a cyclical manner.

[0016] When the filter module rotates to the second chamber with the turntable, it will remove filter screen debris. After the high-pressure gas is output to the second chamber, it must pass through the filter screen before it can be output from the exhaust port. When the gas flows through the filter screen, the airflow direction is in the direction that the debris on the filter screen can be removed from the filter screen. Under the impact of the high-pressure airflow, the debris can be removed from the filter screen.

[0017] Compared with the prior art, in this application, the process of removing the residue on the filter screen does not need to be carried out while the sewage filtration process is stopped. Instead, the cleaning of the residue on the filter screen can be carried out simultaneously with the sewage filtration process, which can significantly improve the sewage treatment efficiency.

[0018] Specifically, the pressure of the high-pressure gas can be set to 1.2-1.5 atmospheres.

[0019] More specifically, there must be a reliable sealing relationship between the turntable and the partition. Specifically, a sealing gasket can be installed on the partition at the contact position with the turntable, and the partition contacts the turntable through the sealing gasket.

[0020] To facilitate the entry of sewage into the channel, a chamfer is provided at the channel in this invention to improve the efficiency of sewage passing through the groove, thereby improving sewage treatment efficiency.

[0021] In one embodiment of the present invention, the filtration module includes a circular frame, a filter screen, and a drive assembly. The filter screen is disposed on the circular frame, which is rotatably connected to the side wall of the channel via a rotating shaft. The direction of the rotating shaft is perpendicular to the vertical axis. The drive assembly is disposed on a turntable and is used to drive the circular frame to rotate around the rotating shaft. When the turntable is running, the circular frame remains stationary relative to the turntable. 。

[0022] In this technical solution, the filter module includes a circular frame, a filter screen, and a drive assembly. The filter screen comes in various models, and different types of filter modules can be replaced according to different usage requirements. The frame can be rotated by the drive assembly, so that both surfaces of the filter screen can be fully utilized in the filtration process.

[0023] Because the circular frame can be flipped, when the filter screen is worn on one side, the other side of the filter screen can be flipped to directly contact the residue, thereby improving the utilization rate of the filter screen and also improving the wastewater treatment efficiency of the device.

[0024] In one technical solution of the present invention, the medium liquid flows through the filter module from bottom to top, and the airflow flows through the filter module from top to bottom.

[0025] In this technical solution, the medium liquid flows through the filtration module from bottom to top, and the airflow flows through the filtration module from top to bottom. That is to say, sewage enters from the bottom of the first chamber and exits from the top of the first chamber, while air enters from the top of the second chamber and exits from the bottom of the second chamber, thereby achieving the filtration of sewage and the removal of residue on the filter screen.

[0026] In one technical solution of the present invention, the outer edge of the circular frame is set as an arc shape, and the arc frame is fitted with the through groove with a clearance.

[0027] In this technical solution, the expected through groove of the circular frame is set to a matching arc shape, which can better match the rotation process of the circular frame, thereby facilitating the adjustment of the circular frame. The two are set to a clearance fit, and the clearance can be set to 0.5-1mm.

[0028] In one technical solution of the present invention, the partition includes a first section and a second section, and the turntable is located between the first section and the second section.

[0029] In this technical solution, the partition includes a first section and a second section, with the first section and the second section sandwiching the turntable between them, and both sections have good sealing performance with respect to the turntable.

[0030] Furthermore, in order to facilitate the rotation of the turntable by the drive component, through holes can be provided on the partition, so that the output shaft of the drive component passes through the through holes and connects to the turntable, so that the turntable can be rotated without interfering with the first and second sections.

[0031] Specifically, the first section is mainly to separate the upper space inside the chamber where the rotating disc faces upwards, while the second section is mainly to separate the lower space inside the chamber where the rotating disc faces downwards, so as to avoid mixing of the filtration process with the residue, thereby ensuring the smooth and efficient operation of both processes.

[0032] In one technical solution of the present invention, the cavity is further provided with a discharge port, and a fan is provided in the second cavity, and the fan is located above the turntable; wherein, the discharge port is located at the bottom of the cavity and corresponds to the position of the second cavity.

[0033] In this technical solution, the discharge port is set in the shape of a funnel to receive the slag that is peeled off by high-pressure air. A fan is installed in the second chamber to generate high-pressure airflow, which acts more directly on the filter screen, thereby achieving more efficient peeling of slag off the filter screen.

[0034] In one technical solution of the present invention, the drive assembly includes a worm wheel and a worm. The worm wheel is located at the outer end of the rotating shaft and outside the circular frame. The worm is rotatably connected to the turntable, and one end of the worm extends out of the turntable. The worm meshes with the worm wheel.

[0035] In this technical solution, the drive component is set as a worm gear drive component. The worm gear rotates together with the circular frame, and the worm meshes with the worm gear. By rotating the worm, the worm gear can be driven to rotate, thereby driving the circular frame and the filter screen to flip.

[0036] In one embodiment of the present invention, the spiral angle of the worm is smaller than the friction angle at which the worm wheel and the worm contact.

[0037] In this technical solution, the worm gear and worm drive are in the form of a self-locking transmission, meaning that torque can only be transmitted from the worm to the worm gear, and not from the worm gear to the worm. At the same time, combined with the high transmission ratio of the worm gear drive, the stability and accuracy of the circular frame control can be guaranteed, while preventing the circular frame from operating due to water flow or airflow impact, thus ensuring that sewage filtration and sludge removal can be carried out efficiently and reliably.

[0038] In one technical solution of the present invention, a receiving groove is provided on the turntable, the driving component is disposed in the receiving groove, and the receiving groove is closed by a fixing block.

[0039] In this technical solution, the drive component is also detachably connected to the turntable along with the circular frame. Both the receiving groove and the fixing block are provided with rotating grooves to allow the worm gear to rotate and connect with both. The worm gear passes through the rotating groove on the fixing block and exits the fixing block.

[0040] Specifically, the fixing block can be connected to the turntable via screws.

[0041] In one technical solution of the present invention, the worm gear is provided with a rotating part, which is used to cooperate with the driving member to realize the driving of the worm gear.

[0042] In this technical solution, the rotating part drives the worm gear to rotate. The rotating part can be set as a wrench head, which can be manually rotated by the wrench, thereby driving the worm gear to rotate and adjusting the angle of the circular frame.

[0043] (III) Beneficial Effects

[0044] The beneficial effects of the present invention are as follows: In the automatic water supply and drainage device of the present invention, sewage enters the cavity through the inlet and enters the first chamber. Under the action of pressure, it flows through the filter module to achieve the filtration action and is then output from the outlet. In the whole process, the filter module can achieve the filtration treatment of sewage.

[0045] Furthermore, the turntable is designed to operate via a drive mechanism, which allows different filtration modules to participate in the wastewater filtration process, thereby improving the wastewater filtration efficiency.

[0046] When the filter module rotates with the turntable to the second chamber, it will remove filter screen debris. After the high-pressure gas is output to the second chamber, it must pass through the filter screen before it can be output from the exhaust port. When the gas flows through the filter screen, the airflow direction is in the direction that the debris on the filter screen can be removed from the filter screen. Under the impact of the high-pressure airflow, the debris can be removed from the filter screen, thus improving the filter screen filtration efficiency.

[0047] Compared with the prior art, in this application, the process of removing debris from the filter screen does not need to be carried out while the sewage filtration process is stopped. Instead, the cleaning of debris from the filter screen can be carried out simultaneously with the sewage filtration process, which can significantly improve the sewage treatment efficiency.

[0079] To better explain and facilitate understanding of this invention, the following description is provided in conjunction with the appendix. Figure 1-5 The present invention will be described in detail through specific embodiments. In this document, directional terms such as "upper," "lower," etc., are used interchangeably. Figure 1 The orientation is used as a reference.

[0080] Example 1:

[0081] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 An embodiment of the present invention provides an automatic water supply and drainage device, including a cavity 1, a turntable 2, a filter module 3, and a drive component 4. The cavity 1 forms a cavity A, which is divided into a first chamber A1 and a second chamber A2 by a partition B. The cavity 1 has an inlet C and an outlet D communicating with the first chamber A1. The turntable 2 is rotatably connected to the cavity 1 around a vertical axis, and the drive component 4 is connected to the turntable 2 to drive it to rotate. The turntable 2 has several through slots I, and the filter module 3 is disposed in one of the through slots I. Wastewater can be filtered through the filter module. The liquid enters the first chamber A1 through the inlet C, flows through the filter module 3, and exits through the outlet D. The filter module 3 is detachably connected to the through channel I. The filter module 3 includes a circular frame 31, a filter screen 32, and a drive assembly 33. The filter screen 32 is disposed on the circular frame 31. The circular frame 31 is rotatably connected to the side wall of the through channel I through a rotating shaft. The direction of the rotating shaft is perpendicular to the vertical axis. The drive assembly 33 is disposed on the turntable 2 and is used to drive the circular frame 31 to rotate. When the turntable 2 is running, the circular frame 31 remains stationary relative to the turntable.

[0082] The cavity 1 is also provided with an air inlet E and an air outlet F that are connected to the second chamber A2. The airflow can enter the second chamber A2 from the air inlet E, and after passing through the filter module 3, it is output from the air outlet F.

[0083] The liquid inlet C and the air outlet F are located on the same side of the turntable 2, while the liquid outlet D and the air inlet E are located on the same side of the turntable 2 and are opposite to the liquid inlet C.

[0084] In this technical solution, the automatic water supply and drainage device includes a cavity 1, a turntable 2, and a filter module 3. The filter module 3 filters the sewage and is installed on the turntable 2. During the use of the device, sewage enters the cavity 1 through the inlet C and enters the first chamber A1. Under pressure, it flows through the filter module 3 to achieve the filtration action and is then output from the outlet D. In the whole process, the filter module 3 can achieve the filtration treatment of sewage.

[0085] Furthermore, the turntable 2 is configured to be driven by the drive component 4, so that different filter modules 3 can participate in the wastewater filtration process, thereby improving the wastewater filtration efficiency.

[0086] Because the circular frame 31 can be flipped, when the filter screen 32 is worn on one side, the other side of the filter screen 32 can be made to come into direct contact with the sludge by flipping the circular frame 31, thereby improving the utilization rate of the filter screen 32 and also improving the wastewater treatment efficiency of the device.

[0087] The driving component 4 can be configured as a stepper motor. When the device is in use, the driving component 4 can be configured to drive the turntable 2 to operate intermittently. That is, after a filter module 3 is in the first chamber A1 or the second chamber A2, the turntable 2 is driven to rotate by an angle.

[0088] Specifically, taking the turntable 2 with 6 filter modules 3 symmetrically arranged in the center as an example, the turntable 2 can be set to stop for 5-10 seconds every 30° rotation and rotate in a cycle.

[0089] Meanwhile, the filter module 3 includes a circular frame 31, a filter screen 32, and a drive assembly 33. The filter screen 32 comes in various models, and different types of filter modules 3 can be replaced according to different usage requirements. The frame can be rotated by the drive assembly 33, so that both surfaces of the filter screen 32 can be fully utilized in the filtration process.

[0090] When the filter module 3 rotates with the turntable 2 to the second chamber A2, it will perform the work of removing residue from the filter screen 32. After the high-pressure gas is output to the second chamber A2, it must pass through the filter screen 32 before the gas can be output from the exhaust port F. When the gas flows through the filter screen 32, the airflow direction is in the direction that the residue on the filter screen 32 can be removed from the filter screen 32. Under the impact of the high-pressure airflow, the residue can be removed from the filter screen 32.

[0091] Compared with the prior art, in this application, the process of removing the residue on the filter screen 32 does not need to be carried out when the sewage filtration process is stopped. Instead, the cleaning of the residue on the filter screen 32 can be carried out simultaneously while the sewage filtration process is being performed, which can significantly improve the sewage treatment efficiency.

[0092] Specifically, the pressure of the high-pressure gas can be set to 1.2-1.5 atmospheres.

[0093] More specifically, there must be a reliable sealing relationship between the turntable 2 and the partition B. Specifically, a sealing gasket can be set on the partition B at the contact position with the turntable 2, and the partition B contacts the turntable 2 through the sealing gasket.

[0094] To facilitate the entry of sewage into the through channel I, a chamfer is provided at the through channel I in this invention to improve the efficiency of sewage passing through the groove, thereby improving the sewage treatment efficiency.

[0095] The cavity 1 is also provided with a discharge port G, and the second chamber A2 is provided with a fan H, which is located above the turntable 2; wherein, the discharge port G is located at the bottom of the cavity 1 and corresponds to the position of the second chamber A2.

[0096] In this technical solution, the discharge port G is set in the shape of a funnel to receive the slag that is peeled off by high-pressure air. A fan H is set in the second chamber A2 to generate high-pressure airflow and make the high-pressure airflow act more directly on the filter screen 32, thereby achieving more efficient peeling of slag from the filter screen 32.

[0097] Example 2:

[0098] Reference Figure 1 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0099] The liquid medium flows from bottom to top through the filter module 3, and the airflow flows from top to bottom through the filter module 3.

[0100] In this technical solution, the medium liquid flows from bottom to top through the filter module 3, and the airflow flows from top to bottom through the filter module 3. That is to say, sewage enters from the lower part of the first chamber A1 and exits from the upper part of the first chamber A1, while air enters from the upper part of the second chamber A2 and exits from the lower part of the second chamber A2, thereby realizing the filtration of sewage and the removal of residue on the filter screen 32.

[0101] Example 3:

[0102] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5In addition to possessing all the technical solutions of any of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0103] The outer edge of the circular frame 31 is set as an arc, and the arc frame is fitted with the through groove I with clearance.

[0104] In this technical solution, the expected through groove I of the circular frame 31 is set to a matching arc shape, which can better match the rotation process of the circular frame 31, thereby facilitating the adjustment of the circular frame 31. The two are set to a clearance fit, and the clearance amount can be set to 0.5-1mm.

[0107] The partition B includes a first section B1 and a second section B2, and the turntable 2 is located between the first section B1 and the second section B2.

[0108] In this technical solution, the partition B includes a first section B1 and a second section B2, which sandwich the turntable 2 between them, and both sections have good sealing performance with respect to the turntable 2.

[0109] Furthermore, in order to facilitate the rotation of the turntable 2 by the drive component 4, a through hole can be provided on the partition B, so that the output shaft of the drive component 4 passes through the through hole and connects to the turntable 2, so that the turntable 2 can be rotated without interfering with the first section B1 and the second section B2.

[0110] Specifically, the first section B1 is mainly to separate the upper space of the rotating disk 2 inside the cavity 1, while the second section B2 is mainly to separate the lower space of the rotating disk 2 inside the cavity 1, so as to avoid the filtration process from mixing with the residue, thereby ensuring the smooth and efficient operation of the two processes.

[0113] The drive assembly 33 includes a worm gear 331 and a worm 332. The worm gear 331 is located at the outer end of the rotating shaft and outside the circular frame 31. The worm 332 is rotatably connected to the turntable 2, and one end of the worm 332 extends out of the turntable 2. The worm 332 meshes with the worm gear 331.

[0114] In this technical solution, the drive component 33 is configured as a worm gear 331 and worm 332 drive component 33. The worm gear 331 rotates together with the circular frame 31, and the worm 332 meshes with the worm gear 331. By rotating the worm 332, the worm gear 331 can be driven to rotate, thereby driving the circular frame 31 and the filter screen 32 to flip.

[0115] In one embodiment of the present invention, the unfolding helix angle of the worm 332 is smaller than the friction angle at which the worm wheel 331 and the worm 332 come into contact.

[0116] In this technical solution, the transmission components of worm gear 331 and worm 332 are in the form of self-locking transmission, that is, torque can only be transmitted to worm gear 331 through worm 332, and cannot be transmitted from worm gear 331 to worm 332. At the same time, combined with the high transmission ratio characteristics of worm gear 331 and worm 332 transmission, the stability and accuracy of the circular frame 31 can be guaranteed, while avoiding the circular frame 31 from running due to water flow or airflow impact, ensuring that sewage filtration and sludge removal can be carried out efficiently and reliably.

[0117] The turntable 2 has a receiving groove J, and the drive assembly 33 is located in the receiving groove J. The receiving groove J is closed by the fixing block K.

[0118] In this technical solution, the drive assembly 33 is also detachably connected to the turntable 2 along with the circular frame 31. Both the receiving groove J and the fixed block K are provided with rotation grooves that allow the worm gear 332 to rotate and connect with them. The worm gear 332 passes through the rotation groove on the fixed block K and exits the fixed block K.

[0119] Specifically, the fixing block K can be connected to the turntable 2 by screws.

[0121] In this technical solution, the rotating part 333 drives the worm gear 332 to rotate. The rotating part 333 can be set as a wrench head, and the rotating part 333 can be manually rotated by the wrench, thereby driving the worm gear 332 to rotate, so as to realize the adjustment of the angle of the circular frame 31.
