Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, specifically to a waste liquid filtration device for incineration pits. Background Technology

[0002] Waste incineration technology, as a relatively mature waste treatment method, has been widely used and plays an important role in environmental governance. In the field of waste incineration, incineration pits are important places for storing waste to be treated. However, for a long time, incineration pits have faced many problems, which have seriously affected the efficiency and cost of waste incineration.

[0003] However, in the existing technology, due to the complexity and variability of incinerated waste, a lot of liquid accumulates in the waste pit. During the waste incineration process, the increased water content of the waste leads to an increase in the amount of auxiliary fuel oil used, which not only increases the cost of waste treatment but also wastes energy and is not conducive to energy conservation and management. In order to solve the above problems, we propose a waste liquid filtration device for incineration pits. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a waste liquid filtration device for incineration pits, comprising a liquid-filling tank; a connecting pipe, the outer side of which is fixedly connected to the top of the liquid-filling tank; a suction pump, the outer side of which is fixedly connected to the end of the connecting pipe away from the liquid-filling tank; a backflush valve, the outer side of which is fixedly connected to the side of the suction pump away from the connecting pipe via a pipe; a suction hose, the outer side of which is fixedly connected to the side of the backflush valve away from the suction pump; and a filter assembly, the top of which is fixedly connected to the bottom end of the suction hose. The filter assembly is used to filter waste. By setting up the filter device, the waste liquid filtered by the filter assembly is absorbed, reducing the wastewater content in the incineration pit, improving the problem of high humidity in the waste pit, making the waste incineration system more stable, and reducing the cost of waste incineration treatment.

[0005] Preferably, the filter assembly includes an outer frame, with a fine sand filter bag slidably connected to the outer side of the outer frame and an activated carbon filter bag slidably connected to the inner side of the outer frame. By setting two layers of filter bags, particles and viscous waste in the waste are isolated, and waste and waste liquid are separated.

[0006] Preferably, a filter box is fixedly connected to the center of the inner cavity of the outer frame. The outer side of the filter box is slidably connected to the outer side of the activated carbon filter bag. The end of the liquid suction hose away from the backflush valve passes through the filter box and is fixedly connected to a liquid suction assembly. The outer side of the liquid suction hose is fixedly connected to the top of the filter box. By setting the filter assembly, the waste is filtered, isolating particles and viscous waste in the waste, avoiding filter box blockage, maximizing the service life of the filter device, improving the problem of high moisture content in the waste pit, making the waste incineration system more stable, and reducing the cost of waste incineration.

[0007] Preferably, the liquid suction assembly includes a backflush air pipe, the top of which is fixedly connected to the bottom of the liquid suction hose, a liquid extraction pipe fixedly connected to the bottom of the backflush air pipe, and a liquid collection pipe fixedly connected to the bottom of the liquid extraction pipe. The liquid collection pipe has holes in its wall to increase the liquid inlet area. A backflush air pipe is reserved above the liquid extraction pipe. When liquid suction stops, the backflush air pipe is turned on to reduce the possibility of the liquid collection pipe becoming blocked and causing a decrease in the liquid suction volume.

[0008] The beneficial effects of this utility model are as follows:

[0009] 1. This utility model reduces the wastewater content in the incineration pit by setting up a filtration device to absorb the waste liquid filtered by the filtration component, thereby improving the problem of high humidity in the waste pit, making the waste incineration system more stable, and reducing the cost of waste incineration treatment.

[0010] 2. By setting up a filter assembly and wrapping the collection pipe with a filter box, this utility model can achieve a protective effect. While filtering waste liquid, it protects the collection pipe to work normally and reduces the phenomenon of being unable to pump liquid due to blockage by particulate matter.

The filter assembly 6 is used for... In the process of filtering waste, the filter assembly 6 is buried in the incineration pit. The waste liquid is driven to flow by the suction pump 3. The waste liquid in the filter assembly 6 flows into the suction hose 5, and then flows into the liquid storage tank 1 through the connecting pipe 2. When the suction stops, the backflush valve 4 is opened to backflush the filter assembly 6 to prevent it from clogging. By setting up a filtration device to absorb the waste liquid filtered by the filter assembly 6, the wastewater content in the incineration pit is reduced, which improves the problem of high humidity in the waste pit, makes the waste incineration system more stable, and reduces the cost of waste incineration.

[0020] The filter assembly 6 includes an outer frame 61, with a fine sand filter bag 62 slidably connected to the outer side of the outer frame 61 and an activated carbon filter bag 63 slidably connected to the inner side of the outer frame 61. During use, external waste is blocked by the fine sand filter bag 62 and the activated carbon filter bag 63, while waste liquid flows through the fine sand filter bag 62 and the activated carbon filter bag 63 into the interior of the outer frame 61. By setting two layers of filter bags, particles and viscous waste in the waste are isolated, and waste and waste liquid are separated.

[0021] A filter box 64 is fixedly connected to the center of the inner cavity of the outer frame 61. The outer side of the filter box 64 is slidably connected to the outer side of the activated carbon filter bag 63. The end of the suction hose 5 away from the backflush valve 4 passes through the filter box 64 and is fixedly connected to the suction assembly 65. The outer side of the suction hose 5 is fixedly connected to the top of the filter box 64. In use, the outer frame 61 is a grid frame. A filter box 64 welded from a filter screen is placed in the middle of the outer frame 61. The outer side of the filter box 64 is a certain distance away from the outer frame 61. An activated carbon filter bag 63 is inserted between the two. A fine sand filter bag 62 is piled up on the outer side of the outer frame 61. During suction, the waste liquid flows along the suction assembly 65 into the inside of the suction hose 5. By setting the filter assembly 6, the waste is filtered, isolating particles and viscous waste in the waste, avoiding clogging of the filter box 64, maximizing the service life of the filter device, improving the problem of high humidity in the waste pit, making the waste incineration system more stable, and reducing the cost of waste incineration.

[0022] The liquid suction assembly 65 includes a backflush air pipe 651, the top of which is fixedly connected to the bottom of the liquid suction hose 5. A liquid extraction pipe 652 is fixedly connected to the bottom of the backflush air pipe 651, and a liquid collection pipe 653 is fixedly connected to the bottom of the liquid extraction pipe 652. Holes 654 are provided in the wall of the liquid collection pipe 653. During use, the waste liquid flows into the liquid collection pipe 653 through the dense holes 654. The waste liquid flows into the liquid suction hose 5 through the liquid extraction pipe 652, and then into the liquid container 1 through the connecting pipe 2. By setting the holes 654, the liquid inlet area of ​​the liquid collection pipe 653 is increased. A backflush air pipe 651 is reserved above the liquid extraction pipe 652. When the liquid suction stops, the backflush air is turned on, which can reduce the situation where the liquid collection pipe 653 is blocked and the liquid suction volume is reduced.

[0023] Working principle:

[0024] In use, the filter assembly 6 is buried in the incineration pit. The outer frame 61 is a grid frame. A filter box 64 made of welded filter screen is placed in the middle of the outer frame 61. The outer side of the filter box 64 is a certain distance away from the outer frame 61. An activated carbon filter bag 63 is inserted between the two. A fine sand filter bag 62 is piled on the outside of the outer frame 61. The waste material from the outside is blocked by the fine sand filter bag 62 and the activated carbon filter bag 63. The waste liquid flows through the fine sand filter bag 62 and the activated carbon filter bag 63 into the interior of the outer frame 61.

[0025] During liquid aspiration, the waste liquid is driven to flow by the liquid aspiration pump 3. The waste liquid flows into the inside of the liquid aspiration pipe 653 through the dense holes 654 on the liquid aspiration pipe 653. The waste liquid flows into the inside of the liquid aspiration hose 5 through the liquid suction pipe 652, and then into the liquid storage tank 1 through the connecting pipe 2. When the liquid aspiration stops, the backflush valve 4 is opened, and the liquid aspiration assembly 65 is backflushed through the backflush air pipe 651 to reduce the possibility of the liquid aspiration volume being reduced due to blockage of the liquid aspiration pipe 653.
