DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] like Figures 1 to 9 As shown, the utility model provides a high-pressure manual backwashing filter device, comprising:

[0034] A base 1, a reducer case 2 is fixedly installed on the left side of the top of the base 1, a filter device body 3 is fixedly installed on the top of the base 1, and the right end of the reducer case 2 and the left end of the filter device body 3 are fixedly connected;

[0035] The locking mechanism 4 is arranged at the top of the reducer housing 2;

[0036] The positioning mechanism 5 is arranged at the front end of the reducer housing 2;

[0037] Among them, the locking mechanism 4 includes a reducer handwheel 401, which is movably installed on the top of the reducer chassis 2, and a handle 402 is fixedly installed on the left side of the top of the reducer handwheel 401. A slot 403 is opened inside the reducer handwheel 401, and a clamping rod 404 is movably sleeved inside the slot 403. A rectangular block 405 is movably sleeved at the bottom of the outer surface of the clamping rod 404, and the rear end face of the rectangular block 405 is fixedly connected to the front end of the reducer chassis 2. A square slider 406 is movably sleeved at the top inside the rectangular block 405, and the inner surface of the square slider 406 is fixedly sleeved with the outer surface of the clamping rod 404. A first spring 407 is fixedly installed at the bottom end of the square slider 406, and the other end of the first spring 407 is fixedly installed at the bottom end inside the rectangular block 405. The first spring 407 will reset the clamping rod 404.

[0038] When the clamping rod 404 moves downward along the inner surface of the rectangular block 405, the square slider 406 will move along with it and compress the first spring 407. When the clamping rod 404 and the clamping slot 403 are separated, the reducer handwheel 401 can be rotated by the handle 402. Under the restoring action of the first spring 407, the square slider 406 will restore the clamping rod 404 to its original position, so that the clamping rod 404 is re-embedded in the clamping slot 403, and the position of the reducer handwheel 401 is locked to prevent the reducer handwheel 401 from accidentally rotating and affecting the normal operation of the backwashing filter device.

[0039] Wherein, the positioning mechanism 5 includes:

[0040] A round block 501, the round block 501 is movably sleeved on the bottom end of the inner portion of the clamping rod 404;

[0041] A connecting rod 502, which is fixedly mounted on the bottom end of the round block 501, the bottom end of the connecting rod 502 passes through the clamping rod 404 and extends to the outside of the clamping rod 404 and is fixedly sleeved with an extension rod 503, the top end of the extension rod 503 is movably connected to the bottom end of the rectangular block 405;

[0042] The positioning block 504 is fixedly mounted on the front side of the middle part of the bottom end of the reducer chassis 2 .

[0043] When the extension rod 503 is pulled, the connecting rod 502 will move with the card rod 404 through the round block 501. Then, the extension rod 503 will be rotated, causing the extension rod 503 to rotate with the connecting rod 502 and the round block 501, so that the extension rod 503 and the positioning block 504 are aligned. At this time, loosening the extension rod 503 will cause the extension rod 503 to move with the card rod 404 and embed into the positioning block 504, thereby positioning the position of the card rod 404.

[0044] Among them, a liquid inlet pressure gauge 6 is fixedly installed on the left side of the top of the filter device body 3, and a liquid outlet pressure gauge 7 is fixedly installed on the right side of the top of the base 1.

[0045] The presence of the liquid inlet pressure gauge 6 and the liquid outlet pressure gauge 7 makes it easy to detect the pressure during liquid inlet and liquid outlet.

[0046] A back plate 8 is fixedly mounted on the front side of the top of the filter device body 3 , and fixing blocks 9 are fixedly mounted on the left and right sides of the top of the back plate 8 , respectively.

[0047] The back plate 8 and the fixing block 9 provide support and fixation.

[0048] The fixing block 9 has a round rod 10 movably sleeved inside, a protective cover 11 is fixedly sleeved on the outer surface of the round rod 10 , and the outer surface of the protective cover 11 is movably connected to the outer surface of the back plate 8 .

[0049] The cooperation between the protective cover 11 and the back plate 8 can realize dustproof protection for the liquid inlet pressure gauge 6 and the liquid outlet pressure gauge 7.

[0050] Among them, a gear 12 is fixedly sleeved in the middle of the outer surface of the round rod 10, and a pointed block 13 is movably connected to the bottom of the outer surface of the gear 12. The bottom end of the pointed block 13 penetrates the back plate 8 and extends to the inside of the back plate 8 and is fixedly installed with a rectangular plate 14. A second spring 15 is fixedly installed at the bottom end of the rectangular plate 14, and the other end of the second spring 15 is fixedly connected to the bottom end inside the back plate 8. The gear 12 will cause the pointed block 13 to move.

[0051] When the gear 12 rotates along with the round rod 10 , since the top of the pointed block 13 is an inclined surface, the rotation of the gear 12 will squeeze the pointed block 13 , so that the pointed block 13 moves downward with the rectangular plate 14 and compresses the second spring 15 .

[0052] Among them, a support block 16 is fixedly installed on the front side of the middle of the top of the base 1, a backwash drain valve 17 is fixedly installed on the top of the support block 16, a drain pipe 18 is fixedly installed at the rear end of the backwash drain valve 17, and the other end of the drain pipe 18 is fixedly connected to the right end of the filter device body 3.

[0053] When the backwash drain valve 17 is opened, the dirt inside the filter device body 3 will be discharged through the drain pipe 18 .

[0054] The working principle and use process of this utility model:

[0055] First, when backwashing, the operator opens the backwash drain valve 17, and then pulls the extension rod 503, so that the extension rod 503 moves along the inner surface of the rectangular block 405 with the clamping rod 404 and the square slider 406 through the connecting rod 502 and the round block 501 and compresses the first spring 407, so that the clamping rod 404 and the clamping groove 403 are separated, and the clamping rod 404 is unlocked from the reducer handwheel 401, and then the extension rod 503 is rotated so that the extension rod 503 rotates around the round block 501 as the axis until the extension rod 503 and the positioning block 504 are aligned, and then the extension rod 503 is released, and the extension rod 503 is restored under the recovery action of the first spring 407. 503 is embedded in the positioning block 504, thereby positioning the clamping rod 404. At this time, the clamping rod 404 and the clamping slot 403 are separated, and then the operator can turn the handle 402 to rotate the reducer handwheel 401, causing the backwashing node disk to rotate 360 ​​degrees, and then close the backwashing drain valve 17. After the backwashing is completed, the device enters the normal filtering state, and then the extension rod 503 and the positioning block 504 are separated and reset. At this time, under the recovery action of the first spring 407, the clamping rod 404 will be re-embedded in the clamping slot 403, thereby completing the locking of the reducer handwheel 401, thereby preventing the reducer handwheel 401 from accidentally rotating and affecting the normal filtering.

[0056] When the operator reads the indications of the inlet pressure gauge 6 and the outlet pressure gauge 7, the shield 11 is moved, so that the shield 11 rotates along the inner surface of the fixed block 9 with the round rod 10, thereby opening the shield 11. As the round rod 10 rotates, the gear 12 rotates together, so that the outer surface of the gear 12 squeezes the pointed block 13, so that the pointed block 13 moves downward with the rectangular plate 14 and compresses the second spring 15. When the shield 11 stops rotating, the second spring 15 is pressed against the outer surface of the gear 12. Under the restoring action of the spring 15, the pointed block 13 and the rectangular plate 14 will return to their original positions, so that the pointed block 13 cooperates with the gear 12 to lock the rotational position of the round rod 10 and the shield 11. After the reading of the indication is completed, the operator again moves the shield 11 to reset it so that the shield 11 cooperates with the back plate 8 to provide dust-proof protection for the inlet pressure gauge 6 and the outlet pressure gauge 7, preventing dust from accumulating on the outer surfaces of the inlet pressure gauge 6 and the outlet pressure gauge 7 and affecting the operator's reading of the indication.
