Description

Technical Field

[0001] The utility model relates to the technical field of slag removal and filtration in water treatment, and particularly relates to a cleaning structure of a slag removal and filtration device. Background Art

[0002] The way of human water treatment has a history of quite many years. Physical methods include using various filter materials with different pore sizes to exclude impurities in water by adsorption or blocking. After long-term use of the existing filter materials, a large amount of scale and impurities are likely to form on the inner wall surface of the filter materials, which is likely to affect the subsequent water treatment work. It is necessary for staff to regularly open the pipeline or water treatment equipment to manually clean the scale on the internal filter materials. This not only has a low scale removal efficiency, but also increases the workload of the staff, and there is also the problem that the cleaned scale is not convenient to be discharged from the inside. Summary of the Utility Model

[0003] Aiming at the above problems, the utility model provides a cleaning structure of a slag removal and filtration device, which is convenient for later processing of impurities on the internal filter element, and at the same time can discharge the cleaned scale from the inside of the device.

[0004] To achieve the above object, the utility model provides the following technical solutions: including a housing, a water inlet, a water outlet and a filter element. A cleaning device is arranged inside the filter element. The cleaning device includes a driving component, a rotating shaft, a supporting platform, a cleaning scraper and a cleaning brush plate. The driving component is in a linkage connection with a transmission rod. The inner peripheral surface of the supporting platform is arranged on the rotating shaft and extends towards the filter element side at the other end. The cleaning scraper and the cleaning brush plate are arranged in an annular array and are respectively fixedly connected to both sides of the supporting platform through bolts.

[0005] By adopting the above technical solutions, the driving component drives the rotating shaft to rotate. The rotating shaft transmits the rotational force to the supporting platform, forming the rotational force for the axial movement of the cleaning scraper and the cleaning brush plate. The cleaning scraper and the cleaning brush plate cooperate with the water flow entering from the water inlet to rotate radially periodically, so as to play a comprehensive cleaning role on the filter element. Different from the working mode of manually cleaning the filter screen, the rotating shaft drives the cleaning brush plate and the cleaning brush plate to rotate for operation, which is convenient for later processing of impurities on the internal filter element, and at the same time can discharge the cleaned scale from the inside of the device.

[0006] The present utility model is further configured such that a transmission rod is connected to the driving assembly. An articulated seat is provided on the transmission rod towards the side of the rotating shaft. A positioning card slot for installing the articulated seat is formed on the rotating shaft. The articulated seat is inserted into the positioning card slot. A fastening member is provided on the articulated seat. A first threaded hole for the fastening member to pass through is formed on the articulated seat. A second threaded hole and a third threaded hole communicating with the first threaded hole are formed on the positioning card slot. The fastening member sequentially passes through the second threaded hole, the first threaded hole, and the third threaded hole and fixes the articulated seat on the positioning card slot.

[0007] By adopting the above technical solution, through the insertion setting of the articulated seat and the positioning card slot, the rotational connection between the transmission rod and the rotating shaft can be formed, and the stability of the connection between the transmission rod and the rotating shaft is further improved by the fixed connection of the fastening member.

[0008] The present utility model is further configured such that a clamping groove is formed on the fastening member near the side of the third threaded hole. A snap ring is inserted into the card slot. The snap ring is tightly clamped in the clamping groove.

[0009] By adopting the above technical solution, the snap ring can further prevent the fastening member from loosening and avoid the shaking of the transmission rod and the rotating shaft during operation.

[0010] The present utility model is further configured such that the cleaning scraper and the cleaning brush plate are perpendicularly and tightly attached to the inner peripheral surface of the filter element. A connecting seat is convexly provided on the cleaning scraper towards the support platform side. The connecting seat and the support platform are limited and tightened by bolts.

[0011] By adopting the above technical solution, the perpendicular setting of the cleaning scraper and the cleaning brush plate can form a fitting work with the filter element, thereby improving the cleaning efficiency.

[0012] The present utility model is further configured such that the cleaning scraper is made of rubber material and the cleaning brush plate is made of plastic material.

[0013] By adopting the above technical solution, the cleaning scraper can increase the single - time cleaning area and improve the cleaning efficiency. The rubber material can reduce the scratching of the filter element while having good dust removal ability. The cleaning brush plate can better penetrate into the gaps in the filter element for comprehensive cleaning, with the effect of efficiently removing dirt and impurities.

[0014] The present utility model is further configured such that a number of reinforcing ribs are conically arranged on the rotating shaft. One end of the reinforcing rib is connected to the rotating shaft, and the other end is inclined and extends to the support platform.

[0015] By adopting the above technical solution, the reinforcing rib can increase the strength when the rotating shaft is connected to the support platform, share the pressure of the connection between the support platform and the cleaning scraper and the cleaning brush plate, and prevent the support platform from breaking and deforming during long-term operation.

[0016] The present utility model is further configured such that a water inlet cavity is connected and arranged on one side of the water inlet. The water inlet cavity is provided with a first water inlet and a second water inlet on the side facing the rotating shaft. A first sewage outlet is provided at the bottom of the water inlet cavity. An L-shaped pipe is connected and arranged on the side of the first sewage outlet facing the housing. A second sewage outlet is provided at the outer end of the L-shaped pipe facing the outside of the housing. A sewage valve is connected and arranged at the second sewage outlet.

[0017] Through the above technical solution, after the cleaning scraper and the cleaning brush plate clean the filter element, dirt and impurities enter the water inlet cavity through the first water inlet and the second water inlet along with the water flow, and are deposited at the bottom of the water inlet cavity. By opening the first sewage outlet, the L-shaped pipe can guide the dirt to be discharged from the water inlet cavity through the second sewage outlet when the sewage valve works, further improving the cleaning efficiency.

[0023] Embodiment: As shown in the appended Figures 1 to 3 cleaning structure of a slag removal and filtering device, including a housing 1, a water inlet 2, a water outlet 3, and a filter element 4 (made of metal). A cleaning device 5 is arranged inside the filter element 4. The cleaning device 5 includes a driving component 8 (specifically a handwheel), a rotating shaft 9, a support platform 10 (the support platform 10 and the rotating shaft 9 are of an integral structure), a cleaning scraper 11, and a cleaning brush plate 12. The driving component 8 is in a linkage connection with a transmission rod 15 (fixedly connected by bolts). The inner peripheral surface of the support platform 10 is arranged on the rotating shaft 9 and extends towards one side of the filter element 4. The cleaning scraper 11 and the cleaning brush plate 12 are arranged in an annular array and are respectively fixedly connected to both sides of the support platform 10 by bolts 14 (there is a gap between adjacent cleaning scrapers 11 and cleaning brush plates 12). The driving component 8 drives the rotating shaft 9 to rotate. The rotating shaft 9 transmits the rotational force to the support platform 10, forming a rotational force for the axial movement of the cleaning scraper 11 and the cleaning brush plate 12. The cleaning scraper 11 and the cleaning brush plate 12 cooperate with the water flow entering from the water inlet 2 to continuously rotate radially in a cycle, thereby playing a role in comprehensively cleaning the filter element 4. Different from the working method of manually cleaning the filter screen, the rotating shaft 9 drives the cleaning brush plate 12 and the cleaning brush plate 12 to rotate for operation, which is convenient for later processing of impurities on the internal filter element, and at the same time, the scale after cleaning can be discharged from the inside of the device.

[0024] As shown in the appended Figure 1 and the appended Figure 2 As shown, a transmission rod 15 (of an integral structure) is connected to the driving component 8. An articulated seat 16 (of an integral structure) is arranged on one side of the transmission rod 15 facing the rotating shaft 9. A positioning card slot 17 for installing the articulated seat 16 is opened on the rotating shaft 9. The articulated seat 16 is inserted into the positioning card slot 17.
