Description

Technical Field

[0001] This invention relates to a solid-liquid separation and conveying mechanism, and more specifically to a conveying mechanism capable of achieving solid-liquid separation and conveying. Background Technology

[0002] In existing technologies, for solid-liquid conveying and separation mechanisms, especially for animal urine, wastewater, and manure such as pig manure in the livestock industry, existing separation and conveying mechanisms often use scraper conveying mechanisms to achieve the separation of liquid and manure. When collecting animal urine and manure, the two are mixed together indiscriminately. Under the action of the scraper and conveying mechanism, they are concentrated together and then left to stand under gravity and time to finally achieve solid-liquid separation. This method of mixing and then separating takes a long time, and the waste liquid contains a large amount of suspended solids, resulting in poor separation effect. Summary of the Invention

When closed, the flexible flap is parallel to the conveyor belt. One end of the flexible flap is hinged to the conveyor belt via a pivot, and the other end of the flexible flap is supported by the support plate of the conveyor belt. When closed, the flexible flap divides the trough into two independent upper and lower accommodating spaces. When opened, the flexible flap is vertically suspended in the trough of the conveyor belt by the pivot alone.

[0022] A solid-liquid separation and conveying mechanism is mainly used to initially achieve solid-liquid separation. It includes a frame 1, a hopper 2, a conveying mechanism 3, a material level detection mechanism, and a control device. The frame 1 is a hollow frame structure. The hopper 2 is installed inside the frame 1. The conveying mechanism 3 is installed on the upper part of the frame 1. The hopper 2 is located directly below the conveying mechanism 3. The control device is used to control the operation of the conveying mechanism 3. The material level detection mechanism is used to detect the material level of the mixture of pig manure and urine in the conveying mechanism 3 and feed it back to the control device. The control device can then control the conveying mechanism 3 according to the material level.

[0023] The conveying mechanism 3 includes a drive mechanism 31, a conveyor belt 32, a flexible flap 33, a first guide mechanism 34, and a second guide mechanism 35. The drive mechanism 31 includes a reversible stepper motor 310, a front roller 311, a rear roller 312, and a synchronous belt 313. The stepper motor 310 drives the front roller 311 to rotate. The front roller 311 and the rear roller 312 are connected by the synchronous belt 313. The conveyor belt 32 is wound around the front roller 311 and the rear roller 312. The drive mechanism 31 drives the conveyor belt 32 to perform intermittent forward and reverse shaking and / or conveying. The conveyor belt 32 includes side guards 321, partitions 322, and support plates 323 on both sides. The partitions 322 are evenly spaced on the conveyor belt 32, and the side guards 321 and partitions 322 form multiple continuous troughs.

[0024] The flexible flap 33 is a flexible material with perforations 330. One end of the flexible flap 33 is hinged to the side rails 321 on both sides of the conveyor belt 32 via a pivot 331. The flexible flap 33 can rotate eccentrically around the conveyor belt 32. The flexible flap 33 is located in the middle of the trough. The flexible flap 33 can be closed and / or opened in the trough. When closed, the flexible flap 33 is parallel to the conveyor belt 32. One end of the flexible flap 33 is hinged to the conveyor belt 32 via a pivot 331. To maintain balance, the other end of the flexible flap 33 is supported by the support plate 323 of the conveyor belt 32. Thus, when closed, the flexible flap 33 divides the trough into two independent upper and lower accommodating spaces. When opened, the flexible flap 33 is vertically suspended in the trough of the conveyor belt 32 by the pivot 331.

[0025] The first guiding mechanism 34 and the second guiding mechanism 35 have the same structure, and both are fixedly mounted on the frame 1. The first guiding mechanism 34 is mounted on the upper side of the front roller 311, and the second guiding mechanism 35 is mounted on the upper side of the rear roller 312. The first guiding mechanism 34 includes a pair of arc-shaped guide rods 300, which are symmetrically mounted above the conveying mechanism 3. Multiple pressure rollers are provided on the side of the arc-shaped guide rods 300 near the conveyor belt 32. These pressure rollers are all installed inside the arc-shaped guide rods 300, and the exposed portions of the pressure rollers are flush with the outer surface of the arc-shaped guide rods. This arrangement is achieved when the conveyor belt 32 turns from top to bottom. When the conveyor belt changes direction, to prevent the flexible flap 33 from flipping around the pivot 331, the arc-shaped guide rod 300 is attached to the upper surface of the flexible flap 33. The arc-shaped guide rod 300 and the flexible flap 33 form rolling friction, causing the flexible flap 33 to deform, thereby maintaining the closed state of the flexible flap 33. When the flexible flap 33 passes the arc-shaped guide rod 300, under the action of gravity, the flexible flap 33 flips around the pivot 331, thus entering the open state. When the conveyor belt 32 changes from bottom to top during the conveying process, the flexible flap 33, guided by the second guide mechanism 35, returns to the closed state from the open state.

[0026] During the separation and conveying process, in order to avoid collision between the first guide mechanism 34 and the second guide mechanism 35 and the partition 322 of the conveyor belt 32, the two ends of the partition 322 are provided with avoidance openings that are adapted to the shape of the first guide mechanism 34 and the second guide mechanism 35.

[0027] The flexible flap 33 can be made of flexible materials such as rubber or plastic.

[0028] The following example, using a pig farm, will be used to illustrate this point.

[0029] The solid-liquid separation and conveying mechanism of this invention is installed below the pigpen in a pig farm. During the breeding process, pigs produce a lot of manure and urine. In the prior art, the collection devices below the pigpen often collect the manure and urine together, rarely separating and conveying the solid and liquid, or conventional separation and conveying mechanisms do not achieve good technical results. Therefore, continuous conveying is required. This invention is mainly based on this problem. By using a solid-liquid separation and conveying mechanism, the separation of pig manure and urine can be initially achieved, thereby improving the cleaning efficiency of the farm.

[0030] like Figure 1 As shown, a solid-liquid separation and conveying mechanism is installed below the pigpen, through which pig urine and manure enter the solid-liquid separation and conveying mechanism.

[0031] The control method of the present invention is as follows:

[0032] Step 1: Collect urine and pig manure. Set the intermittent shaking time T according to the scale of the farm and the length of the pigpen. During the intermittent shaking time T, the stepper motor of the drive mechanism will rotate in both directions to make the conveyor belt shake. At the beginning of the intermittent shaking time T, the mixture of urine and pig manure flowing down from the manure slat enters the tank and falls onto the flexible flap. With the shaking of the conveyor belt, the urine enters the independent collection space at the bottom of the tank through the holes.

[0033] The perforation is a micro-hole, which prevents pig manure from falling through the perforation while allowing urine to pass through.

[0034] As time goes on, more and more urine and pig manure mixture falls onto the flexible flap. The urine gradually fills the space below the flexible flap in the tank. At this time, the pig manure is filtered into the space above the flexible flap. The tanks are also interconnected due to the clearance openings of the conveyor belt partitions, which further facilitates the flow of urine. The clearance openings at both ends of the conveyor belt are closed due to the obstruction of the arc-shaped guide rods.

[0035] Step 2: Separation of urine and pig manure. When the material level detection mechanism detects that the trough of the conveying mechanism is full, the control device controls the stepper motor to run forward, and the upper conveyor belt conveys towards the first guide mechanism. At this time, the flexible flap in the first trough near the first guide mechanism is guided by the arc-shaped guide rod and changes direction and bends together with the conveyor belt, forming a certain gap between the front end of the flexible flap and the conveyor belt. The pig manure in the trough above the flexible flap stays on the flexible flap due to its stickiness. At this time, the urine flows out through the gap.

[0036] Step 3: Pig manure falls. As the conveying mechanism operates, the flexible flap, driven by the conveyor belt, passes through the first guiding mechanism. After the flexible flap is separated from the support and guidance of the arc-shaped guide rod, it moves to the lower layer of the conveying mechanism. Under the action of gravity, the flexible flap, under its own weight and the weight of the pig manure, will rotate around the axis. At this time, the flexible flap and the conveyor belt are in the open state, and the flexible flap is suspended in the trough of the conveyor belt. The solid pig manure will fall into the pig manure recycling device below the conveying mechanism, completing the separation and conveying of the pig manure from the flexible flap in the first trough.

[0037] This process is repeated to separate and transport the flexible flaps in all the troughs in the lower layer of the conveyor belt from the pig manure in the upper layer.

[0038] Step 4: As the conveyor belt runs, when the flexible flap in the first trough moves to the second guiding mechanism, the flexible flap in the first trough changes from the open state to the closed state due to the guidance of the arc-shaped guide rod of the second guiding mechanism, thereby collecting urine and pig manure again.

[0039] It should be noted that when collecting urine and pig manure, the conveyor belt must empty all the troughs before starting again. That is, each cycle changes the position of the upper and lower layers of the conveyor belt. The entire conveyor belt rotates half a turn, causing the upper and lower layers of the conveyor belt to exchange positions. After the upper trough of the conveyor belt is full, the conveyor belt starts to operate. When all the troughs on the upper layer of the conveyor belt move to the lower layer of the conveying mechanism, one collection and separation cycle is completed. The troughs that were originally on the lower layer of the conveyor belt move to the upper layer of the conveying mechanism for collection, thus realizing the cycle.

[0040] During the intermittent shaking time T, the stepper motor of the drive mechanism operates intermittently and briefly in both directions, causing the conveyor belt to shake. This shaking allows urine to pass through the holes on the flexible flap into the lower receiving space, and also causes the trough in the lower layer of the conveying mechanism to shake, allowing pig manure to fall off more effectively, thus achieving automatic cleaning.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
