Description

Technical Field

[0001] The utility model relates to the technical field of pig farm wastewater treatment, in particular to a pig farm wastewater filtering device. Background Art

[0002] With the rapid development of animal husbandry in my country, the large-scale and intensive development of animal husbandry has become an inevitable trend. Animal husbandry refers to the production sector that raises livestock and poultry to obtain animal products or draft animals by grazing, confinement or a combination of the two. Among them, large-scale pig farms have higher livestock and poultry breeding technology and unified management, which reduces costs and improves economic benefits. However, in order to improve the quality of pork during the breeding process, breeders need to control the growth environment of pigs to ensure that they can grow in a better environment. Therefore, the pig farm needs to be flushed and cleaned every day. The cleaning water is mixed with the pig manure and urine in the pig farm, resulting in a large amount of pig farm wastewater.

[0003] However, pig farm wastewater is not useless waste pollutant. It is a mixture of pig excrement (pig urine and some pig manure) and pig house flushing water. Among them, pig manure is rich in nitrogen, phosphorus, potassium and other substances. After being recycled, it can be fermented into an organic biofertilizer with high nutritional content. After being applied to the soil, it can improve soil properties and increase crop yields. Therefore, how to efficiently filter and separate pig farm wastewater is a technical problem that technicians in this field urgently need to solve. Utility Model Content

[0004] The purpose of the utility model is to provide a pig farm wastewater filtering device to solve the above-mentioned problems in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The utility model provides a pig farm wastewater filtering device, comprising a separation box and a purification tank, wherein a rectangular filter screen is provided inside the separation box, and the rectangular filter screen can be freely replaced by extraction, and the separation box is divided into two parts by the rectangular filter screen, wherein a feed pipe and a first water inlet pipe and a second water inlet pipe are arranged on the top of one part, and the first water inlet pipe and the second water inlet pipe are respectively connected to high-pressure water spray heads;

[0007] The other part of the separation box is communicated with the purification tank through a first water pump.

[0008] A water outlet is arranged at the bottom end of the side wall of the purification pool.

[0009] Furthermore, the high-pressure water spray head is arranged at the top of one side of the rectangular filter screen, and a rotating shaft is provided between the high-pressure water spray head and the first water inlet pipe and the second water inlet pipe, which can rotate freely to perform all-round flushing of the rectangular filter screen to prevent the filter screen from being blocked due to the deposition of too much pig manure and other substances during the filtration process, thereby affecting the filtration effect.

[0010] Furthermore, a liquid outlet is provided at the bottom of the purification tank, which is connected to a liquid outlet pipe, and the liquid outlet pipe is connected to a feed pipe at the top of the separation box. A second water pump is provided on the liquid outlet pipe to reintroduce the unqualified pig farm wastewater into the separation box for further filtration and separation.

[0011] Furthermore, a valve is provided at the connection between the liquid outlet pipe and the feed pipe to prevent the raw materials in the feed pipe from flowing into the liquid outlet pipe and damaging the water pump.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model studies a filtering and processing device for pig farm manure water, which realizes the separation of pig manure and wastewater in the pig farm by setting a rectangular filter in the separation box. In order to improve the separation effect, the device sets a freely rotatable high-pressure water spray head on the top of the rectangular filter, which can realize all-round flushing of the filter to prevent the filter from being blocked during the filtering process and affecting the separation efficiency. In addition, the device adopts a high-pressure water spray head with a large water spray force, so that the substances stuck on the filter can be quickly washed away, thereby improving the flushing effect.

[0014] Since pig manure is a good raw material for organic biological fertilizer, in order to reduce the loss of pig manure in the separation process and to re-separate the wastewater that was not separated cleanly in the first separation process and was introduced into the purification tank, the device sets a liquid outlet at the bottom of the purification tank to reintroduce unqualified wastewater into the separation box, and use a finer filter mesh to filter and separate it again to improve the filtering effect.

[0015] The device completes the filtering and treatment operation of pig farm manure and effectively separates pig manure and sewage. It has a simple structure and increased practicality. It also has good purification effect and high efficiency for wastewater treatment in large-scale pig farms. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Example 1

[0025] Reference Figure 1-3 The utility model provides a pig farm manure filtering device, comprising a separation box (4) and a purification tank (8). A rectangular filter screen (5) is provided inside the separation box (4). The rectangular filter screen can be freely replaced by extraction. The rectangular filter screen (5) divides the separation box (4) into two parts.

[0026] A feed pipe (1) and a first water inlet pipe (2) and a second water inlet pipe (3) are arranged at the top of one part, the feed pipe (1) extends to the middle and lower part of the separation box (4), the first water inlet pipe (2) and the second water inlet pipe (3) are respectively connected to a high-pressure water spray head (13) through a rotating shaft (12), and the high-pressure water spray head (13) is arranged at the top of one side of the rectangular filter screen (5) to achieve all-round flushing of the rectangular filter screen (5) to prevent clogging;

[0027] Another part of the separation box (4) is connected to the purification tank (8) via a first water pump (6);

[0028] A water outlet (9) is provided at the bottom end of the side wall of the purification tank (8), and the purified wastewater is discharged from the water outlet (9);

[0029] A liquid outlet is also provided at the bottom of the purification tank (8), which is connected to a liquid outlet pipe (11). The liquid outlet pipe (11) is connected to a feed pipe (1) at the top of the separation box (4), a valve (10) is provided at the connection point, and a second water pump (7) is provided on the liquid outlet pipe (11).

[0030] The working principle of the utility model is as follows:

[0031] In actual use, the pig farm wastewater is introduced into the separation box (4) through the feed pipe (1), and filtered through the rectangular filter screen (5), wherein the pig manure is intercepted by the rectangular filter screen (5), and then the first pump (6) is turned on to pump the filtered wastewater into the purification tank (8). During this period, the rectangular filter screen (5) is flushed with a high-pressure water spray head (13) to prevent pig manure and other substances from sticking to the filter screen and causing blockage, thereby affecting the filtering effect.

[0032] The wastewater in the purification tank is tested. If there is still a small amount of fine pig manure and other substances in the wastewater, the second pump (7) and the valve (10) are opened to reintroduce the wastewater into the separation box (4) through the outlet pipe (11) at the bottom of the purification tank (8), and a finer rectangular filter screen (5) is replaced to filter the wastewater until the wastewater is almost free of pig manure and other substances. The wastewater is then discharged from the outlet (9) at the bottom of the side wall of the purification tank (8), thereby completing the filtration of the pig farm wastewater.
