Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-4 The utility model provides a new technical solution: a slag-liquid separation and filtering device that is easy to install, comprising a filtering device box 1 and a filter screen plate 3, wherein a lifting assembly 2 for driving the filter screen plate 3 to lift and lower for filtering is provided in the filtering device box 1;

[0029] The filter plate 3 is provided with a filter plate installation and cleaning assembly, which is used to clean the filter plate when replacing the filter plate so that the filter plate can be quickly removed;

[0030] The filter plate installation and cleaning assembly includes two slide rails 4, two gears 7, a worm 8, a housing 10, a lower fixed plate 11, an upper movable plate 12, a worm wheel 16, a wheel disc 17, a movable slot frame 18 and a tapered tooth groove 19;

[0031] A coarse-hole filter plate is provided in the filter screen plate 3, and a conical tooth groove 19 is provided on the upper movable plate 12. The conical tooth groove 19 is an inclined surface with a certain inclination angle. The same conical tooth groove 19 is provided on the lower fixed plate 11. The lower surfaces of the lower fixed plate 11 and the conical tooth groove 19 are both fitted with the coarse-hole filter plate of the filter screen plate 3.

[0032] Furthermore, the filter plate installation and cleaning assembly further includes two sliders 5, which are slidably connected to corresponding slide rails 4, and the two slide rails 4 are fixedly connected to the upper surface of the filter plate 3 on both sides, and a worm shaft 6 is rotatably connected between the two sliders 5;

[0033] The two gears 7 are fixedly sleeved at both ends of the worm shaft 6. The two slide rails 4 are provided with tooth grooves that mesh with the gears 7. The worm 8 is fixedly sleeved at the middle end of the worm shaft 6. The outer surface of the worm shaft 6 is rotatably connected to two worm fixing plates 9. The lower fixing plate 11 is fixedly connected to the two worm fixing plates 9.

[0034] Furthermore, the outer shell 10 is fixedly connected to the lower surface of the lower fixed plate 11 , and is fixedly mounted on the outer surfaces of the lower fixed plate 11 and the upper movable plate 12 . The outer shell 10 is used to protect the transmission mechanism, and a handle is fixedly connected to the outer shell 10 .

[0035] Furthermore, the upper movable plate 12 is arranged on the upper surface of the lower fixed plate 11, and two waist-shaped sliding grooves 14 are opened on the upper movable plate 12. Two fixing pins 13 are fixedly connected to the lower fixed plate 11, and the two fixing pins 13 are slidably connected to the corresponding waist-shaped sliding grooves 14.

[0036] Furthermore, a worm gear fixing frame 15 is fixedly connected to the lower fixing plate 11, and a worm gear 16 is meshedly connected to the worm 8. The worm gear 16 is rotatably connected to the worm gear fixing frame 15, and the lower end of the rotating shaft of the worm gear 16 rotates through the lower surface of the worm gear fixing frame 15 and the wheel disc 17 is fixedly sleeved thereon;

[0039] Furthermore, during use, when the filter coarse-hole plate on the filter screen plate 3 is clogged too much and needs to be replaced and installed, the handle on the outer shell 10 is pulled to drive the filter plate installation and cleaning assembly to move in the direction of the slide rail 4 and the slider 5. At the same time, when the slide rail 4 moves, the engagement of the gear 7 with the tooth groove on the slide rail 4 can enable the gear 7 to drive the worm shaft 6 to rotate, and the rotating worm shaft 6 can drive the rotation. The rotating worm 8 can drive the wheel 17 to rotate by engaging with the worm gear 16. When the wheel 17 rotates, the rotating shaft on it can drive the upper movable plate 12 to move back and forth through the movable slot frame 18, so that the upper movable plate 12 can move back and forth along the axis of the fixed pin 13 and the waist-shaped slide groove 14.

[0040] Furthermore, when the upper movable plate 12 moves back and forth, the conical tooth grooves 19 thereon overlap alternately with the conical tooth grooves 19 on the lower fixed plate 11, and the tips of the conical tooth grooves 19 can be inserted into the gaps between the messy hair and impurities blocked on the coarse-hole filter plate on the filter screen plate 3.

[0041] Furthermore, by setting the filter plate installation cleaning assembly, the conical tooth grooves 19 on the upper movable plate 12 and the conical tooth grooves 19 on the lower fixed plate 11 are alternately overlapped and continuously fit with the coarse filter plate on the filter mesh plate 3. This can make it possible for even if the messy hair and impurities are not cut and separated by the alternately overlapping wheel discs 17, they can be pulled out from the holes of the coarse filter plate by the continuously moving lower fixed plate 11 and upper movable plate 12, which further improves the cleaning efficiency of the coarse filter plate on the filter mesh plate 3, and also improves the ease of use of the slag-liquid separation and filtration equipment to a certain extent.

[0042] Working principle: During use, when the coarse filter plate on the filter screen plate 3 is clogged too much and needs to be replaced and installed, the handle on the outer shell 10 is pulled to drive the filter plate installation and cleaning assembly to move in the direction of the slide rail 4 and the slider 5. At the same time, when the slide rail 4 moves, the engagement of the gear 7 with the tooth groove on the slide rail 4 can make the gear 7 drive the worm shaft 6 to rotate, and the rotating worm shaft 6 can drive the rotation. The rotating worm 8 can drive the wheel 17 to rotate by engaging with the worm wheel 16. When the wheel 17 rotates, the rotating shaft on it can drive the upper movable piece 12 to move back and forth through the movable slot frame 18, so that the upper movable piece 12 can move back and forth along the axis of the fixed pin 13 and the waist-shaped slide groove 14.

[0043] Furthermore, when the upper movable plate 12 moves back and forth, the conical tooth grooves 19 thereon overlap alternately with the conical tooth grooves 19 on the lower fixed plate 11, and the tips of the conical tooth grooves 19 can be inserted into the gaps between the messy hair and impurities blocked on the coarse-hole filter plate on the filter mesh plate 3. When the conical tooth grooves 19 on the upper movable plate 12 overlap alternately with the conical tooth grooves 19 on the lower fixed plate 11, the inclined conical surfaces of the conical tooth grooves 19 can squeeze and cut off a part of the hair and other impurities stuck on the two conical tooth grooves 19, thereby making it possible for the messy hair and impurities blocked on the coarse-hole filter plate on the filter mesh plate 3 to be separated from the coarse-hole filter plate, which enables the coarse-hole filter plate to be effectively cleaned.

[0044] Furthermore, by setting the filter plate installation and cleaning assembly, the conical tooth grooves 19 on the upper movable plate 12 and the conical tooth grooves 19 on the lower fixed plate 11 are alternately overlapped and continuously fit with the coarse filter plate on the filter mesh plate 3. This enables even if the messy hair and impurities are not cut and separated by the alternately overlapping wheel discs 17, they can be pulled out from the holes of the coarse filter plate by the continuously moving lower fixed plate 11 and upper movable plate 12.
