DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] As Figures 1 to 6As shown, in the prior art, the inventor finds that the following problems exist: first, the pull rod of the movable rod is pulled back and is affected by the spring to rebound downward, which hinders the operator from taking out the filter, especially when single person operates, which reduces the work efficiency; second, after the inlet inclined pipe is released, the unfiltered water remaining in the pipe directly enters the filter box from the pipe opening, pollutes the filtered water, and causes secondary pollution; third, after the filter device is released from the bolt fixing, the lack of grabbing point on the filter makes it inconvenient to take out, reduces the work efficiency, and causes trouble to the workers;

[0026] Therefore, the inventor provides a wastewater filtering device for lead-bismuth slag smelting plants, which comprises a box body 1, a filter 2, and a water inlet device 3. The filter 2 is arranged on the right side inside the box body 1, and the water inlet device 3 is arranged on the left side inside the box body 1. The water inlet device 3 further comprises a water inlet pipe body 4, a limiting mechanism 5, a check mechanism 6, and a lifting mechanism 7. The limiting mechanism 5 is arranged on the left end of the large sleeve 8 of the water inlet pipe body 4. The check mechanism 6 is arranged inside the water inlet pipe body 4. The lifting mechanism 7 is arranged at the bottom of the filter 2.

[0027] With the above scheme, when the device needs to be cleaned, the cover plate and the bolt on the filter 2 are first removed, then the handle 9 on the water inlet device 3 is pulled backward, the large sleeve 8 of the water inlet device 3 is pulled out of the filter 2, the limitation on the filter 2 is released, and when the handle 9 is pulled to the upper side of the limiting groove 12, the limiting mechanism 5 is pulled out and clamped into the limiting groove 12, which limits the water inlet device 3 in the folded state, facilitating single person to replace and clean the filter 2, and improving the work efficiency. At the same time, during the folding process of the water inlet device 3, the check mechanism 6 inside the large sleeve 8 is closed to close the water inlet pipe, preventing unfiltered wastewater from entering the water tank and causing pollution. During the folding process of the water inlet device 3, the lifting mechanism 7 is linked to convert the backward power into upward thrust to push the filter device out of the box body 1 by a distance, which can lift the filter 2 upward while releasing the limitation of the filter 2, facilitating the worker to take out the filter 2, and improving the work efficiency.

[0028] Further, the limiting mechanism 5 further comprises a handle 9, a limiting spring 10, an outer shell 11, and a limiting groove 12. The outer shell 11 is arranged on the left end of the large sleeve 8 of the water inlet pipe body 4. The limiting spring 10 is arranged inside the outer shell 11. The handle 9 is arranged at the bottom of the limiting spring 10. The limiting groove 12 is arranged on the front and rear sides of the box body 1 and is slidably connected with the handle 9.

[0029] Wherein, the handle 9 is pushed down by the limiting spring 10 in the shell 11, when the water inlet device 3 is in the unfolded state, the handle 9 is not limited, the limiting mechanism 5 and the water inlet device 3 can automatically expand and contract according to the external force; when the handle 9 is pulled to convert the water inlet device 3 to the folded state, the handle 9 comes above the limiting groove 12 and is pushed down by the limiting spring 10, so that the handle 9 is clamped into the limiting groove 12 to maintain the folded state of the water inlet device 3, and when the water inlet device 3 needs to be unfolded, the handle 9 is only lifted to release the limitation, so that the water inlet device 3 is converted to the unfolded state, which can facilitate the replacement and cleaning work of the filter 2 when a single person operates, and improve the work efficiency.

[0030] Further, the check mechanism 6 further comprises a check plate 13 and a reset block 14, the check plate 13 is arranged at the middle part of the inner side of the large sleeve 8 and is connected with the inner side of the large sleeve 8 through a rotating shaft, and the reset block 14 is arranged at the right end of the small sleeve 15 of the water inlet pipe body 4 and is connected with the inner wall of the large sleeve 8 through sliding;

[0031] Wherein, the check plate 13 is rotated and attached to the right side bottom of the small sleeve 15 after the water inlet device 3 is contracted, and the pipeline is blocked, and the check plate 13 is opened by the action of the reset block 14 after the water inlet device 3 is unfolded, so that the pipeline is opened.

[0032] Further, the check plate 13 is provided with a circular plate with a diameter larger than the inner diameter of the small sleeve 15 and smaller than the outer diameter of the small sleeve 15;

[0033] Wherein, the circular plate can cover the bottom of the small sleeve 15 when the water inlet device 3 is in the folded state, so as to achieve the purpose of blocking the pipeline.

[0034] Further, the end of the reset block 14 is provided with a triangular plate with increasing height to the right;

[0035] Wherein, during the unfolding process of the water inlet device 3, the large sleeve drives the check plate 13 to stretch forward, and the check plate 13 continuously opens after colliding with the triangular plate at the end of the reset block 14, so that the pipeline is opened.

[0036] Further, the lifting mechanism 7 further comprises a supporting plate 16, a sliding groove 17, a connecting rod a 18, a connecting rod b 19, a connecting rod c 20, a sliding rod 21 and a connecting rod d 22, the supporting plate 16 is arranged below the filter 2, the sliding groove 17 is arranged on the water tank body 1 below the supporting plate 16, the left end of the connecting rod a 18 is hingedly connected with the left end of the sliding groove 17, the right end of the connecting rod a 18 is hingedly connected with the left end of the connecting rod b 19, the right end of the connecting rod b 19 is rotatably connected with the sliding rod 21, the sliding rod 21 is arranged between the sliding grooves 17 and is slidably connected with the sliding grooves 17, the right end of the connecting rod c 20 is slidably connected with the sliding rod 21, the left end of the connecting rod c 20 is hingedly connected with the right end of the connecting rod d 22, and the left end of the connecting rod d 22 is hingedly connected with the large sleeve left end below the water inlet pipe body 4;

[0037] Among them, when the water inlet device 3 shrinks, the large sleeve 8 moves to the left, driving the connecting rod d22 to move to the left. The connecting rod d22 pulls the sliding rod 21 at the right end of the connecting rod c20 to move, so that the connection between the connecting rod a18 and the connecting rod b19 rotates with the left end of the connecting rod a18 as the axis, thereby pushing up the support plate 16 and lifting the filter 2, making it easier for the staff to take out the filter 2 and improving work efficiency.

[0038] Furthermore, a sliding groove is provided between the connecting rod c20 and the sliding rod 21;

[0039] Among them, the slide rod 21 has a sliding distance between the leftmost end and the rightmost end of the connecting rod c20. During this distance, the connecting rod c20 moves while the slide rod 21 does not move. This can ensure that the lifting mechanism 7 can lift the filter 2 only after the large sleeve 8 pulls out the filter 2, thereby ensuring the linkage between the water inlet device 3 and the lifting mechanism 7.

[0040] To sum up, a limiting mechanism 5 is provided on the water inlet device 3 of the device. After the water inlet device 3 releases the filter 2, the water inlet device 3 can be restricted to the retracted state, which is convenient for a single person to replace and clean the filter 2, thereby improving work efficiency; a non-return mechanism 6 for controlling the closure of the pipeline is added at the end of the water inlet pipe. After the water inlet device 3 is retracted, the pipeline can be closed to prevent unfiltered wastewater in the pipeline from leaking into the water tank and causing pollution; a lifting mechanism 7 is provided, and the lifting mechanism 7 is linked to the water inlet device 3. When the water inlet device 3 is retracted, the filter 2 can be lifted upward, which is convenient for the staff to take out the filter 2, thereby improving work efficiency.

[0041] The working principle of this utility model:

[0042] When the equipment needs to be cleaned, the cover plate and bolts on the filter 2 are first removed, and then the handle 9 on the water inlet device 3 is pulled backward to draw the large sleeve 8 of the water inlet device 3 out of the filter 2, thereby releasing the restriction on the filter 2. When the handle 9 is pulled to switch the water inlet device 3 to the retracted state, the handle 9 comes above the limiting groove 12 and is pushed downward by the limiting spring 10, so that the handle 9 is stuck in the limiting groove 12 to maintain the retracted state of the water inlet device 3. When the water inlet device 3 needs to be unfolded, the restriction can be released by simply lifting the handle 9, so that the water inlet device 3 is switched to the extended state. This makes it convenient for one person to replace and clean the filter 2, thereby improving work efficiency.

[0043] When the water inlet device 3 is retracted, the return plate will rotate and fit on the right bottom of the small sleeve 15 after the water inlet device 3 is retracted, thus blocking the pipeline.

[0044] At the same time, the lifting mechanism 7 is linked to convert the backward power into upward thrust, drive the connecting rod d22 to move left, the connecting rod d22 pulls the slide rod 21 at the right end of the connecting rod c20 to move to make the connecting rod a18 and the connecting rod b19 pivot at the left end of the connecting rod a18, in the process, the slide rod 21 has a sliding distance between the leftmost end and the rightmost end of the connecting rod c20, in the distance, the connecting rod c20 moves and the slide rod 21 is stationary, so that the lifting mechanism 7 can lift the filter 2 after the large sleeve 8 is pulled out, and the lifting mechanism 7 lifts the filter 2, which facilitates the staff to take out the filter 2 and improves the work efficiency;

[0045] When the filter 2 is cleaned and replaced, the filter 2 is placed back into the water tank, and the handle 9 is lifted to release the restriction, so that the water inlet device 3 is converted to the stretched state, and in the process of unfolding the water inlet device 3, the large sleeve 8 drives the check plate 13 to stretch forward, the lifting mechanism 7 falls back to the initial position, and the check plate 13 continuously opens after colliding with the triangular plate at the end of the reset block 14, so that the pipeline is opened, and in the process, the pipeline is automatically closed to prevent unfiltered wastewater in the pipeline from leaking into the water tank to cause pollution;

[0046] After that, the bolts and the cover plate on the filter 2 can be installed to put the equipment into normal use;

[0047] Thus, the working principle of the device is described.

[0048] It should be noted that in this paper, relationship terms such as first and second 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 the entities or operations.
