Description

Technical Field

[0001] This utility model relates to the field of tobacco production line technology, specifically to a filter water tank with self-cleaning capability. Background Technology

[0002] In current tobacco production lines, waste gas treatment equipment is gradually transitioning from traditional filter-based methods to more environmentally friendly and cleaner water mist adsorption methods.

[0003] As the volume of water treated by water mist adsorption gradually increases, the water consumption also gradually increases. However, the original tobacco production line lacks water inlet and drainage facilities, so it is necessary to add dedicated water treatment equipment.

[0004] Regarding the wastewater treatment after use, there are currently two approaches. One is to design a large water tank to temporarily store the wastewater. After the first cleaning is completed, the wastewater tank is transferred to another location for discharge. This method requires a larger water tank as the scale increases, which places certain demands on installation space. The other approach is to design a comprehensive water treatment system that filters the wastewater and then recycles it. Although the secondary recycled water is not as clean as the purified water, it can still be used in some scenarios where the water cleanliness is not high. This not only improves water utilization efficiency but also eliminates the need for an excessively large water tank.

[0005] However, due to the need for recycling, these water tanks require timely cleaning to prevent excessive wastewater accumulation from affecting the filtration and water usage processes.

[0006] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a self-cleaning water tank that does not affect the normal operation of filtration and water recycling.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a water tank with self-cleaning capability, comprising a water tank, a filter assembly, and a cleaning assembly; The water tank is provided with a filter chamber at the top and a water storage chamber at the bottom, and the filter chamber and the water storage chamber are connected to each other. The filtration assembly includes a cylindrical filter screen installed in the filtration chamber and a spiral conveying mechanism installed in the cylindrical filter screen. The water tank has a wastewater inlet and a filter residue outlet at its two ends, respectively, corresponding to the two ends of the cylindrical filter screen. The spiral conveying mechanism works with the cylindrical filter screen to filter the filter residue in the wastewater and push it to the filter residue outlet. The filtered water is discharged from the cylindrical filter screen into the water storage chamber. The cleaning assembly includes at least two rows of flushing water holes installed on the top of the filter chamber and spaced apart along the head-to-tail direction of the filter chamber, with a flushing nozzle installed in each flushing water hole; A rotating flushing pipe is installed in the water storage chamber. The two ends of the rotating flushing pipe are rotatably connected to the side wall of the water tank. Several water spray nozzles are distributed on the pipe wall. The rotating flushing pipe is driven to rotate by an external drive mechanism.

[0009] Based on the above, the two rows of flushing water holes are symmetrically distributed in the vertical plane where the axis of the cylindrical filter screen is located.

[0010] Based on the above, the included angle between the two rows of flushing water holes and the axis of the cylindrical filter screen is between 60° and 120°.

[0011] Based on the above, the rinsing coverage of the two rows of rinsing water holes and the rotating rinsing pipe includes the entire outer circumferential surface of the cylindrical filter screen.

[0012] Based on the above, the inner cavity shape and outer contour of the water storage cavity are semi-circular arcs, and the rotating flushing pipe is installed at the axis of the water storage cavity.

[0013] Based on the above, the two ends of the rotary flushing pipe are mounted on the two side walls of the water tank via bearings, and the water inlet side of the rotary flushing pipe is connected to an external water supply pipeline via a rotary water supply connector.

[0014] Based on the above, the inner cavity and outer contour of the filter chamber are semi-circular arcs, the overall contour of the water tank is shaped like an eye mask, the water tank is tilted as a whole, and a filter cake box is provided below the filter cake outlet.

[0015] Based on the above, the water storage cavity is provided with a drain outlet at the bottom, a secondary water supply outlet on the lower side, and an overflow outlet and a level gauge interface at the top.

[0016] Based on the above, the water tank is integrated on a support with rollers, and the filter cake box is equipped with an independent mobile trolley.

[0017] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model integrates a filter component in a water tank and is equipped with a cleaning component for rinsing the filter component. On the one hand, the volume of the filter and water storage is greatly reduced after integration, and wastewater can be treated and reused in real time. On the other hand, the cleaning component can clean the filter component and the inside of the water tank in a timely manner, avoiding the problems of easy clogging and faster dirt accumulation that exist after the integrated design.

[0023] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0024] like Figures 1-4 As shown, a self-cleaning water filter tank includes a water tank 1, a filter assembly 2, and a cleaning assembly 3.

[0025] The water tank 1 has a filter chamber 11 at the top and a water storage chamber 12 at the bottom. The filter chamber 11 and the water storage chamber 12 are connected to each other. The inner cavity and outer contour of the filter chamber 11 and the water storage chamber 12 are both semi-circular arcs. The overall contour of the water tank 1 is shaped like an eye mask. The water tank 1 is tilted as a whole. The filter cake box 4 is set below the filter cake outlet.

[0026] The water storage chamber 12 is provided with a drain outlet 13 at the bottom, a secondary water supply outlet 14 on the lower side, an overflow outlet 15 and a level gauge interface 16 at the top.

[0027] In this embodiment, for easy transfer, the water tank 1 is integrated on a support 5 with wheels, and the filter residue box 4 is equipped with an independent mobile trolley for easy transfer of filter residue.

[0028] The filter assembly 2 includes a cylindrical filter screen 21 installed in the filter chamber and a spiral conveying mechanism 22 installed in the cylindrical filter screen. The water tank 1 has a wastewater inlet 23 and a filter residue outlet 24 at its two ends, respectively, corresponding to the two ends of the cylindrical filter screen. The spiral conveying mechanism 22 works with the cylindrical filter screen 21 to filter the filter residue in the wastewater and push it to the filter residue outlet. The filtered water is discharged from the cylindrical filter screen into the water storage chamber. The spiral conveying mechanism 22 is driven to rotate by an external motor. It propels the filter residue forward through the spiral propulsion capability. At the same time, during the pushing and squeezing process, water is separated and discharged into the water storage chamber 12 through the cylindrical filter screen 21.

[0029] The cleaning component 3 includes at least two rows of flushing water holes 31 installed on the top of the filter chamber 11 and arranged at intervals along the head and tail direction of the filter chamber 11. Each flushing water hole 31 is equipped with a flushing nozzle (not shown in the figure, only the installation position is provided). The spray direction of the flushing nozzle is aligned with the cylindrical filter screen 21 to remove impurities attached to the cylindrical filter screen 21 and the spiral conveying mechanism 22.

[0030] A rotary flushing pipe 32 is installed in the water storage chamber 12. The rotary flushing pipe 32 is installed at the axis of the water storage chamber 12. Both ends of the rotary flushing pipe 32 are installed on the side wall of the water tank through bearings. The water inlet side of the rotary flushing pipe 32 is connected to an external water supply pipeline through a rotary water supply connector 34.

[0031] The rotating flushing pipe 32 has several spray nozzles 33 distributed on its pipe wall. The rotating flushing pipe 32 is driven to rotate by an external drive mechanism. In this embodiment, it is connected to the motor output end of the screw conveyor mechanism 22 through a chain or belt and a corresponding speed change mechanism, sharing the same power source.

[0032] The rotary flushing pipe 32 is mainly used to flush the lower part of the cylindrical filter screen 21, and also to flush the cylinder wall.

[0033] In other embodiments, the rotating flushing pipe 32 may also be equipped with a separate drive motor.

[0034] In terms of spatial distribution, the two rows of rinsing water holes 31 are symmetrically distributed in the vertical plane where the axis of the cylindrical filter screen 21 is located, with the included angle between 60° and 120°. The rinsing coverage of the two rows of rinsing water holes 31 and the rotating rinsing pipe 32 includes the entire outer circumference of the cylindrical filter screen 21, so as to clean the cylindrical filter screen 21 in all directions.

[0035] Brief description of the work process: Wastewater from the tobacco production line, after air purification using water mist centrifugation, or wastewater from cleaning, is introduced into the wastewater inlet 23 of the water tank 1 through a wastewater pipe. The wastewater, containing a large amount of solid residue, enters the filter assembly and is fed forward by the screw conveyor 22. During the feeding process, due to the presence of the cylindrical filter screen 21 and the presence of extrusion pressure, the filter residue and water are separated. The filter residue is sent to the filter residue outlet 24 and falls into the filter residue box 4, while the wastewater enters the water storage chamber 12. The wastewater can be reused.

[0036] Since the treatment of filter residue and the reuse of wastewater are concentrated in the same water tank, the cylindrical filter screen 21 and the water tank itself will get dirty very quickly. During the working interval, the cleaning component 3 is used to clean the cylindrical filter screen 21 and the entire water tank to avoid clogging of the cylindrical filter screen 21. After the entire water tank is transferred to a suitable environment, the wastewater is discharged.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
