Description

Technical Field

[0001] The invention relates to the technical field of livestock excrement harmless treatment equipment, and in particular to a livestock excrement pre-drying treatment system. Background Art

[0002] Livestock farms produce a large amount of livestock manure, which can be used as raw materials for organic fertilizer. When using livestock manure to process organic fertilizer, it is generally necessary to first deliquify the manure. The deliquification processing equipment includes a casing and a spiral extrusion structure installed on the casing. The manure enters from one end of the spiral extrusion structure and then moves to the other end. During the process, the manure is squeezed to separate the liquid and is collected in the casing, while the deliquated part leaves through the other end, is collected and sent to the next process (such as drying). In the actual processing process, the liquid part collected in the casing may need to be collected multiple times and then processed regularly (larger farms have multiple manure collection points, and the amount of processing at each collection point is different, and the casing will not be filled at one time (the casing volume can be made larger to collect more liquid for unified processing)). The long storage time may cause serious gas production in the casing. In the next processing process, these gases may flow back through the feed port, causing the manure to be pushed out of the feed port during the feeding process, causing inconvenience to the processing. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a livestock manure pre-drying treatment system, which solves the problem in the prior art that the gas generated in the casing may cause the manure to be pushed out during the processing.

A discharge pipe is provided in the casing, and the discharge pipe extends downward into the liquid collecting chamber; a second conveying pipe is extended laterally, one end of the second conveying pipe is connected with the discharge pipe, and the other end is fixedly connected with a discharge hopper located outside the casing, a second spiral is arranged in the second conveying pipe, and a plurality of second through holes connecting the inside and the liquid collecting chamber are opened on the second conveying pipe; an exhaust pipe located at the upper end thereof and connecting the inside and the outside of the liquid collecting chamber is also fixedly connected to the casing, the second spiral is also fixedly connected with an extension shaft coaxially, and the extension shaft is also fixedly connected with a rotating fan blade located in the liquid collecting chamber and separated from the second conveying pipe.

[0005] In the above embodiment, during operation, the first spiral and the second spiral can be started synchronously, or the second spiral can be started first. When the second spiral is running, it drives the gas outward through the second conveying pipe and then conducts it out of the discharge hopper. At the same time, the exhaust pipe is also provided for gas to be conducted out, which will not cause the gas to flow back through the feed hopper. Therefore, the feeding process can proceed smoothly and the feces will not be pushed out in the feed hopper in the opposite direction, which solves the problem in the prior art that the gas generated in the casing may cause the feces to be pushed out during the processing.

[0006] Furthermore, the second conveying pipe and the arc-shaped orifice plate are staggered.

[0007] Furthermore, the end surface of the second delivery pipe in the liquid collecting chamber is open, and a mounting plate close to the opening of the second delivery pipe is fixedly connected to the extension shaft, and the rotating fan blades include a plurality of blades fixedly mounted on the mounting plate at equal intervals.

[0008] Furthermore, the casing is also fixedly connected with a connecting cover, the second conveying pipe passes through the connecting cover to the outside of the casing, the connecting cover is connected with the liquid collecting chamber, and the discharge hopper is located outside the connecting cover.

[0009] Furthermore, the casing is also fixedly connected with a fixing ring fixedly surrounding the outside of the second conveying pipe, and the upper side of the connecting cover is fixedly connected to the fixing ring.

[0010] Furthermore, the second conveying pipe includes a first conveying section located in the liquid collecting chamber, and a second conveying section located in the connecting cover. The second conveying section has a gradually changing inner diameter, and the inner diameter of one end close to the first conveying section is larger than that of the other end. The outer edge of the second spiral is equidistantly matched with the inner wall of the second conveying pipe.

[0011] Furthermore, a pair of first support bars and a second support bar located between the two first support bars are fixedly connected in the liquid collecting chamber, and filter plates are overlapped between the two first support bars and the second support bars respectively.

[0012] Furthermore, a partition plate is fixedly connected to the second support bar, and the two filter plates are respectively located on both sides of the partition plate.

[0013] Furthermore, the casing is also provided with an opening and closing door located above the filter plate.

[0014] Furthermore, the bottom of the casing is fixedly connected to a pair of mounting plates located on both sides thereof, and the bottom surfaces at both ends of the two mounting plates are respectively recessed with mounting grooves, in which wheels are installed; a reinforcing plate is also fixedly connected between the two mounting plates, and a vertically extending positioning rod is threadedly connected to the reinforcing plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Through the second conveying pipe that runs across the inside and outside of the casing, the gas is pushed outward during its operation and discharged through the discharge hopper. At the same time, the exhaust pipe is also provided to conduct the gas outward, which will not cause the gas to flow back through the feed hopper. Therefore, the feeding process can proceed smoothly and the feces will not be pushed out in the reverse direction in the feed hopper, which solves the problem in the prior art that the gas generated in the casing may cause the feces to be pushed outward during the processing.

[0024] In an exemplary embodiment, Figure 1As shown, this embodiment provides a livestock manure pre-drying treatment system, which includes: a casing 1, a liquid collecting chamber 2 is arranged in the casing 1, and a discharge pipe 3 connected to the liquid collecting chamber 2 is fixedly connected to the bottom of the casing 1; a first conveying pipe 4 extending laterally, the first conveying pipe 4 is fixedly installed at the bottom of the casing 1 and an arc-shaped orifice plate 5 is arranged between each other, and a plurality of first through holes connecting the first conveying pipe 4 and the liquid collecting chamber 2 are opened on the arc-shaped orifice plate 5, a first spiral 6 is arranged in the first conveying pipe 4, one end of the first conveying pipe 4 is also fixedly connected to a feed hopper 7 connected thereto, and the other end is also fixedly connected to a discharge pipe 8 connected thereto, And the discharge pipe 8 extends downward into the liquid collecting chamber 2; a second conveying pipe 9 extends laterally, one end of the second conveying pipe 9 is connected to the discharge pipe 8, and the other end is fixedly connected to a discharge hopper 10 located outside the casing 1, a second spiral 32 is arranged in the second conveying pipe 9, and a plurality of second through holes connecting the inside and the liquid collecting chamber 2 are opened on the second conveying pipe 9; the casing 1 is also fixedly connected to an exhaust pipe 11 located at its upper end and connecting the inside and outside of the liquid collecting chamber 2, the second spiral 32 is also fixedly connected to an extension shaft 12 coaxially, and the extension shaft 12 is also fixedly connected to a rotating fan blade 13 located in the liquid collecting chamber 2 and separated from the second conveying pipe 9.

[0025] In the above embodiment, during operation, the first spiral 6 and the second spiral 32 can be started synchronously, or the second spiral 32 can be started first. When the second spiral 32 is running, it drives the gas outward through the second through hole to enter the second conveying pipe 9, and then guides the gas outward from the discharge hopper 10, which will not cause the gas to flow back through the feed hopper 7. Therefore, the feeding process can be carried out smoothly, and the feces will not be pushed out in the feed hopper 7 in the opposite direction, which solves the problem in the prior art that the gas generated in the casing 1 during the processing may cause the feces to be pushed outward; during the processing, the extended shaft 12 is rotated together with the second spiral 32, and can also drive the rotating fan blades 13 to rotate, so that the gas flow in the liquid collecting chamber 2 is accelerated, so that it can also be discharged through the exhaust pipe 11 A portion of the gas is exported; more specifically, the casing 1 is also equipped with a first drive motor 14 and a second drive motor 15, which are respectively connected to the first spiral 6 and the second spiral 32 to drive them to rotate. In more detail, the second drive motor 15 is connected to the extension shaft 12, and at the same time, the first drive motor 14 and the second drive motor 15 can be located on opposite sides of the casing 1, which is conducive to the balanced weight of the equipment; when the system is running, feces enters from the feed hopper 7, and moves from one end of the first conveying pipe 4 to the other end driven by the first spiral 6, and then enters the second conveying pipe 9 through the discharge pipe 8, and then moves to the other end driven by the second spiral 32, and then is exported through the discharge hopper 10. During the process, the arc-shaped orifice plate 5 and the second delivery pipe 9 can be used for liquid to be discharged into the liquid collecting chamber 2 to achieve separation; in more detail, the second delivery pipe 9 and the arc-shaped orifice plate 5 are staggered to prevent the liquid of the arc-shaped orifice plate 5 from falling onto the second delivery pipe 9. Furthermore, the end surface of the second delivery pipe 9 located in the liquid collecting chamber 2 is open, so that when the second spiral 32 is running, the gas in the liquid collecting chamber 2 can enter the second delivery pipe 9 more smoothly, and then be introduced into the discharge hopper 10 through the second delivery pipe 9 and then discharged to the outside of the casing 1. During the process, it can also enter the second delivery pipe 9 through the second through hole. Furthermore, a mounting plate 16 close to the open part of the second delivery pipe 9 is fixedly connected to the extension shaft 12, and the rotating fan blades 13 It includes multiple equidistantly fixed installations on the installation disk 16, the installation disk 16 provides an installation base for the rotating fan blades 13, and also blocks the area between the arc-shaped orifice plate 5 and the second delivery pipe 9, preventing the liquid from rotating along the extension axis 12 and being driven into the second delivery pipe 9. At the same time, during the operation of the second spiral 32, part of the liquid can also flow into the liquid collecting chamber 2 through the open end face of the second delivery pipe 9, cooperating with the second through hole to more smoothly separate the liquid from the second delivery pipe 9; in more detail, the diameter of the installation disk 16 can be smaller than the inner diameter of the second delivery pipe 9, so as to prevent the liquid from entering the second delivery pipe 9 while avoiding a larger range of blocking gases from entering the second delivery pipe 9 through the open end face of the second delivery pipe 9.

[0026] In a further embodiment, Figure 1As shown, the casing 1 is also fixedly connected with a connecting cover 17, the second delivery pipe 9 passes through the connecting cover 17 to the outside of the casing 1, the connecting cover 17 is connected with the liquid collecting chamber 2, the discharge hopper 10 is located outside the connecting cover 17, all the second through holes can be connected with the liquid collecting chamber 2, the lower inner wall of the connecting cover 17 is inclined, so that the liquid flows downward more smoothly into the liquid collecting chamber 2, in more detail, the casing 1 is also fixedly connected with a fixing ring 18 wrapped around the outside of the second delivery pipe 9, the upper side of the connecting cover 17 is fixedly connected to the fixing ring 18, the fixing ring 18 strengthens the connection strength between the second delivery pipe 9 and the casing 1, and also partially provides a connection basis for the connecting cover 17;

[0027] In further detail, the second conveying pipe 9 includes a first conveying section 19 located in the liquid collecting chamber 2, and a second conveying section 20 located in the connecting cover 17. The second conveying section 20 has a gradually changing inner diameter, and the inner diameter of one end close to the first conveying section 19 is larger than that of the other end. The outer edge of the second spiral 32 is equidistantly matched with the inner wall of the second conveying pipe 9, and the second spiral 32 also includes an equal diameter section and a variable diameter section. When in the position of the variable diameter section, the space between the second spiral 32 and the second conveying pipe 9 gradually becomes smaller, so that the degree of compression is further gradually increased, the dehydration efficiency is improved, and ultimately the feces achieves a better pre-drying effect.

[0028] like Figure 1-3 As shown, a pair of first support bars 21 and a second support bar 22 located between the two first support bars 21 are fixedly connected in the liquid collecting chamber 2, and filter plates 23 are overlapped between the two first support bars 21 and the second support bars 22, respectively. The filter plates 23 are located below the first through hole, the second through hole and the connecting cover 17. The liquid discharged after deliquidation will fall on the filter plates 23 and be filtered again, so that there are fewer solid impurities in the liquid below, and these intercepted solid impurities can be recovered and returned to the feed hopper 7.

[0029] Furthermore, a partition plate 24 is fixedly connected to the second support bar 22, and two filter plates 23 are respectively located on both sides of the partition plate 24. The two filter plates 23 can be against the partition plate 24, and there is a gap between the other end and the inner wall of the casing 1 to facilitate the removal and placement of the filter plates 23. In more detail, the filter plates 23 in this scheme can also be inclined, and the end close to the two filter plates 23 is the lower end, so that after the liquid falls on the filter plate 23, even if it flows, it will gather to the middle to avoid clogging the gap at a higher position; further In the scheme, baffles 25 are fixedly connected to both sides of the filter plate 23, and the orthographic projection of the arc-shaped orifice plate 5 is located on the filter plate 23 below it, and the first pipe section of the second delivery pipe 9 also has an orthographic projection on the filter plate 23 below it, and is located between the two baffles 25, so that the liquid will fall on the filter plate 23 and smoothly achieve re-filtration. At the same time, there is a large distance between the baffle 25 and the inner wall of the casing 1, so that the filter plate 23 can be taken and placed smoothly. In further detail, the connecting cover 17 is also located between the two baffles 25 of the filter plate 23;

[0030] Furthermore, the casing 1 is also provided with an opening and closing door 26 located above the filter plate 23. After the opening and closing door 26 is opened, the filter plate 23 can be cleaned. At the same time, the space after the opening and closing door 26 is opened is also larger to ensure that the filter plate 23 can be smoothly taken out or put in (the width of the filter plate 23).

[0031] like Figure 1 As shown, in a further scheme, the bottom of the casing 1 is also fixedly connected to a pair of mounting plates 27 located on both sides thereof, and the bottom surfaces of both ends of the two mounting plates 27 are respectively recessed with mounting grooves 28, and wheels 29 are installed in the mounting grooves 28; a reinforcing plate 30 is also fixedly connected between the two mounting plates 27, and a vertically extending positioning rod 31 is threadedly connected to the reinforcing plate 30, so that the system can be conveniently moved through the wheels 29, and the reinforcing plate 30 can connect the two mounting plates 27 into one body, and the structural strength can be further improved. At the same time, the arranged positioning rod 31 can be rotated downward when needed to press into the ground to play an auxiliary role in stabilizing the casing 1 (generally, some ground in farms is non-concrete ground, and the arranged positioning rod 31 can be inserted into it, or holes for the positioning rod 31 to enter can be set at each feces collection point, and the positioning rod 31 presses into the system to make it more stable, and the arranged positioning rod 31 can be two or more).

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
