Description

Technical Field

[0001] The invention belongs to the technical field of filters, in particular to a double-filter material filter. Background Art

[0002] The double-media filter is a highly efficient and easy-to-operate sewage treatment equipment. It uses larger-particle anthracite and smaller-particle corundum as filter media, so that the filter layer distribution is close to the most ideal filter layer state, achieving the best pollution interception effect.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0027] like Figures 1 to 7 As shown, the embodiment of the present invention provides a double-filter material filter, including a filter tank 1, a water inlet pipe 2 is fixedly sleeved in the middle of the top of the filter tank 1, a water outlet pipe 3 is fixedly sleeved in the middle of the bottom end of the filter tank 1, a cylinder 4 is fixedly installed on the four corners of the bottom end of the filter tank 1, a base 5 located below the water outlet pipe 3 is movably sleeved at the bottom of the outer surface of the cylinder 4, a bottom plate 6 located inside the base 5 is fixedly installed at the bottom end of the cylinder 4, and vertical plates 7 are fixedly installed on the left and right sides of the bottom end of the bottom plate 6, respectively, and the number of the vertical plates 7 is two, and a circular shaft 8 is fixedly sleeved inside the two vertical plates 7, and a circular roller 9 is movably sleeved on the outer surface of the circular shaft 8, and the left and right ends of the circular roller 9 are movably connected to the opposite surfaces of the two vertical plates 7, respectively, and a pneumatic cylinder 10 is fixedly installed at the bottom of the left end of the base 5, and the right end of the pneumatic cylinder 10 penetrates the base 5 and extends to the inside of the base 5 and is fixedly installed with a push block 11, which is movably sleeved on the left side of the bottom end inside the base 5, and the outer surface of the push block 11 is movably connected to the outer surface of the circular roller 9.

[0028] When the pneumatic cylinder 10 is started, the push block 11 will move along the bottom end inside the base 5. Since the right side of the top of the push block 11 is an inclined surface and is movably connected to the outer surface of the round roller 9, as the push block 11 moves, the push block 11 will generate a thrust on the round roller 9, pushing the round roller 9 to move with the bottom plate 6 through the round shaft 8 and the vertical plate 7, thereby making the bottom plate 6 move with the cylinder 4 and the filter tank 1, so that the vibration of the filter tank 1 can be achieved, so that the filter material inside the filter tank 1 can be spread out to prevent the filter material from piling up.

[0029] A feeding pipe 12 is fixedly sleeved on the left side of the top of the filter tank 1 , and a maintenance pipe 13 is fixedly sleeved on the bottom of the left side of the outer surface of the filter tank 1 .

[0030] The existence of the feeding pipe 12 will facilitate the addition of filter material, while the existence of the inspection pipe 13 will facilitate inspection.

[0031] A partition 17 is fixedly sleeved on the bottom end of the filter tank 1 , a water filter cap 18 is fixedly installed on the top end of the partition 17 , and the bottom end of the water filter cap 18 penetrates the partition 17 and extends to the outside of the partition 17 .

[0032] The existence of the partition 17 supports the filter material, and the water filter cap 18 can filter the filter material to prevent the filter material from being discharged from the water outlet pipe 3.

[0033] Among them, a cross bar 19 is fixedly sleeved on the top of the inside of the filter tank 1, a driving motor 20 is fixedly installed on the right side of the top of the filter tank 1, and a driving shaft 21 is fixedly sleeved on the other end of the output shaft of the driving motor 20. The bottom end of the driving shaft 21 passes through the filter tank 1 and the cross bar 19 and extends to the bottom of the cross bar 19. A driving wheel 22 is fixedly sleeved on the bottom of the outer surface of the driving shaft 21, and the bottom end of the driving wheel 22 is movably connected to the top of the cross bar 19.

[0034] When the driving motor 20 is started, the driving shaft 21 will drive the driving wheel 22 to rotate.

[0035] Among them, a long rod 23 is movably sleeved inside the middle end of the cross bar 19, and a driven wheel 24 is fixedly sleeved on the top of the outer surface of the long rod 23. The bottom end of the driven wheel 24 is movably connected to the top end of the cross bar 19, and the driven wheel 24 is connected to the driving wheel 22 through a transmission belt 25.

[0036] Since the driven wheel 24 is connected to the driving wheel 22 via the transmission belt 25 , when the driving wheel 22 rotates, the driven wheel 24 will rotate under the action of the transmission belt 25 .

[0037] The outer surface of the long rod 23 is movably sleeved with a movable rod 26 located below the cross rod 19 , and the bottom of the outer surface of the movable rod 26 is fixedly sleeved with a scraper rod 27 .

[0038] When the movable rod 26 rotates, the scraper rod 27 will rotate together with it.

[0039] The movable rod 26 has limit slots 28 on both sides thereof, and the limit blocks 29 are movably sleeved on the bottom of the limit slots 28 . The outer surface of the limit blocks 29 is fixedly connected to the outer surface of the long rod 23 .

[0040] Due to the existence of the limiting groove 28 and the limiting block 29, when the long rod 23 rotates, the movable rod 26 is driven to rotate together.

[0041] Among them, a horizontal plate 30 is movably sleeved on the top of the outer surface of the movable rod 26, and an adjustment plate 31 is fixedly installed on the right side of the top of the horizontal plate 30. The top of the adjustment plate 31 passes through the filter tank 1 and extends to the outside of the filter tank 1. A round rod 32 is fixedly installed on the top of the right end of the adjustment plate 31.

[0042] When the round rod 32 is pushed, the movable rod 26 will move along the outer surface of the long rod 23 through the adjustment plate 31 and the cross plate 30, and the outer surface of the movable rod 26 and the inner surface of the cross plate 30 are movably connected, which will not affect the rotation of the movable rod 26.

[0043] Among them, a power motor 14 is fixedly installed at the rear right side of the top of the filter tank 1, and a power shaft 15 is fixedly sleeved on the other end of the output shaft of the power motor 14. A rotating rod 16 is fixedly sleeved on the right side of the outer surface of the power shaft 15. The left end of the rotating rod 16 is movably connected to the right end of the adjustment plate 31, and the inner surface of the rotating rod 16 is movably sleeved on the outer surface of the round rod 32.

[0044] When the power motor 14 is started, the power shaft 15 will drive the rotating rod 16 to rotate, so that the rotating rod 16 generates a thrust on the round rod 32 .

[0045] Working principle and usage process:

[0046] The filter materials inside the double-filter-material filter are laid out in sequence from bottom to top with a pebble cushion layer, corundum filter materials and anthracite filter materials. When the operator adds the filter materials into the filter tank 1 through the feeding pipe 12, the pneumatic cylinder 10 is started to move the push block 11. At this time, the round roller 9 movably connected to the push block 11 will be pushed by the push block 11 to move the round shaft 8 and the vertical plate 7 upward, and the bottom plate 6 will move with the cylinder 4 and the filter tank 1. This process is repeated to make the filter tank 1 vibrate, thereby spreading the filter materials inside the filter tank 1 flat, preventing the filter materials from piling up and affecting the filtering effect of the filter.

[0047] Subsequently, the operator starts the power motor 14 according to the height of the filter material, so that the power shaft 15 drives the rotating rod 16 to rotate. Since the internal movable sleeve of the rotating rod 16 is connected with the round rod 32, as the rotating rod 16 rotates, the inner wall of the rotating rod 16 will generate a thrust on the outer surface of the round rod 32, pushing the round rod 32 through the adjustment plate 31 and the cross plate 30 to move along the outer surface of the long rod 23 with the movable rod 26 and the scraper rod 27 until the scraper rod 27 contacts the top of the top layer of filter material. With the mutual cooperation of various mechanisms, the height of the scraper rod 27 is adjusted, thereby improving its convenience and applicability.

[0048] Then the operator can start the normal filtering operation. At the same time, the operator starts the driving motor 20, so that the driving shaft 21 drives the driving wheel 22 to rotate. Since the driving wheel 22 is connected to the driven wheel 24 through the transmission belt 25, the driven wheel 24 will rotate with the long rod 23 under the action of the transmission belt 25. Due to the existence of the limit groove 28 and the limit block 29, the movable rod 26 will rotate with the scraper rod 27 along with the long rod 23, so as to achieve the flattening of the top layer of filter material with the help of the scraper rod 27, so as to prevent the top layer of filter material from failing to return to a horizontal state due to irregular movement of the filter material during filtering and cleaning.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
