DETAILED DESCRIPTION

[0027] 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.

[0028] The utility model provides a technical solution, a filter press capable of liquid level warning, comprising:

[0029] See also Figure 1 and Figure 2 as well as Figure 3 , filter press unit 1, used for solid-liquid separation by filtration, this scheme is a structural improvement of the non-electronic component part based on the filter press of the prior art, wherein the combination of the filter press unit 1, the filter press plate 2 and the liquid level display controller 6 is a common filter press product with liquid level warning that has been promoted in the prior art.

[0030] See also Figure 1 and Figure 2 as well as Figure 3 The filter press plate 2 is installed inside the filter press unit 1 and is used for filtering the liquid for solid-liquid separation. Circular grooves 21 are evenly spaced outside the filter press plate 2. The inside of the circular grooves 21 is slidably connected to the outside of the filter press unit 1. The circular grooves 21 facilitate the sliding connection between the filter press plate 2 and the inside of the filter press unit 1. A square groove 22 is provided outside the filter press plate 2. The inside of the square groove 22 is connected to the outside of the second protrusion 5. The square groove 22 facilitates the scraper 49 to clean the inside of the filter press port 3.

[0031] The filter press port 3 is installed inside the filter press plate 2 and is used for filtering liquid.

[0032] See also Figure 3 and Figure 4 as well as Figure 5 The cleaning mechanism 4 is installed on the front and back sides of the filter press plate 2 and is used to discharge the solids filtered out by the filter press port 3.

[0033] The cleaning mechanism 4 includes a first airbag 41. The gas inside the first airbag 41 can be pressed into the second airbag 43, thereby expanding the second airbag 43. The first airbag 41 is wrapped with memory foam. The cleaning mechanism 4 is connected to the filter plate 2. The memory foam can make the first airbag 41 return to its original position and expand after being squeezed.

[0034] See also Figure 3 and Figure 4 as well as Figure 5 The front and back sides of the first airbag 41 are connected with a hose 42, which can guide the gas. The end of the hose 42 away from the first airbag 41 is connected with the second airbag 43. Springs can be set inside the second airbag 43 and the first airbag 41 to increase the return effect of the first airbag 41 and the second airbag 43. The top of the second airbag 43 is fixedly connected to the top of the slotted block 44.

[0035] See also Figure 3 and Figure 4 as well as Figure 5 The bottom of the second airbag 43 is connected to the top of the slide plate 45, and the slotted block 44 is connected to the square groove 22. The second airbag 43 can drive the slide plate 45 to move. The outer part of the second airbag 43 is provided with a slotted block 44, and the slotted block 44 can guide the slide plate 45. The inner part of the slotted block 44 is slidably connected with the slide plate 45, and the slide plate 45 can slide inside the slotted block 44.

[0036] See also Figure 3 and Figure 4 as well as Figure 5 The top of the slide plate 45 is fixedly connected to the bottom of the second airbag 43, and a hollow column 46 is fixedly connected between the two slide plates 45. The hollow column 46 can connect the slide bar 48. The opposite ends of the two hollow columns 46 are fixedly connected with a first spring 47, and the first spring 47 can pull the slide bar 48 to return.

[0037] See also Figure 3 and Figure 4 as well as Figure 5 The two hollow columns 46 have opposite ends slidably connected with a slide rod 48, which can transmit a scraper 49. The slide rod 48 is connected to a first spring 47, and a scraper 49 is fixedly connected between the two slide rods 48. A short arm 4010 is fixedly connected to the bottom of one end of the slide rod 48, and the short arm 4010 can be connected to the first protrusion 4011.

[0038] See also Figure 3 and Figure 4 as well as Figure 5 The second protrusion 5 is staggered with the end opposite to the short arm 4010, and the outside of the second protrusion 5 is slidably connected with the outside of the first protrusion 4011. The second protrusion 5 and the short arm 4010 are staggered to avoid the second protrusion 5 from conflicting with the short arm 4010, so that the second protrusion 5 can only conflict with the first protrusion 4011. The front side of the short arm 4010 is fixedly connected with the first protrusion 4011, and the first protrusion 4011 can conflict with the second protrusion 5.

[0039] See also Figure 3 and Figure 4 as well as Figure 5 The second protrusion 5 is installed inside the filter press plate 2 to provide a driving force. The second protrusion 5 can drive the first protrusion 4011 to move.

[0040] The liquid level display controller 6 is installed on the left side of the top of the filter press unit 1 and is used for liquid level warning.

[0041] This solution uses the method of connecting the filter press unit 1 to an external liquid source, starting the filter press unit 1 to filter the liquid to separate the solid and the liquid. After the filter press unit 1 is finished working, the solid separated from the solid and the liquid is retained on both sides of the filter press plate 2.

[0042] When multiple filter press plates 2 are closed, the mutual squeezing will drive the first airbag 41 to retract, and the gas inside the first airbag 41 will be discharged into the second airbag 43 through the hose 42. The second airbag 43 will expand after the gas enters the interior, and the expanded second airbag 43 drives the slide plate 45 to move, and the moving slide plate 45 drives the scraper 49 to move. At the same time, after the filter press plate 2 is released from the closed filtering state, the first airbag 41 returns to its original position, and drives the scraper 49 to return to its original position. The returned scraper 49 cleans the solid waste on the outside of the filter press plate 2. Through the added cleaning mechanism 4, when the filter press plate 2 returns after filtering, the solid waste on both sides of the outside of the filter press plate 2 is automatically scraped and swept to prevent the solid waste from being stuck on both sides of the filter press plate 2, thereby avoiding delays in the use of the filter press unit 1 when manual cleaning is required by the staff.

[0043] When the hollow column 46 drives the slide bar 48 to move, it drives the first protrusion 4011 to collide with the second protrusion 5, and then drives the short arm 4010 to drive the slide bar 48 to move. The moving slide bar 48 returns to its original position through the first spring 47. This reciprocating movement increases the contact area between the scraper 49 and the filter press plate 2, and then increases the cleaning effect of the cleaning mechanism 4 on solid waste. Through the cooperation of the added short arm 4010 with the first protrusion 4011 and the second protrusion 5, the cleaning effect of the scraper 49 on the solid waste adhered to the outside of the filter press plate 2 is increased, and the solid waste adhered to the outside of the filter press plate 2 is completely cleaned.
