Description

Technical Field

[0001] This utility model belongs to the field of livestock and poultry manure treatment technology, specifically relating to a high-efficiency dry-wet separation device for livestock and poultry manure. Background Technology

[0002] In the livestock farming sector, the separation of wet and dry manure is a crucial step in achieving resource utilization and environmentally friendly treatment. Currently, most common wet and dry separation equipment adopts the principle of screw extrusion. The typical approach involves directly pumping or feeding the collected manure into the separator's inlet, relying on the propulsion and extrusion of the internal screw blades to achieve solid-liquid separation. However, this direct injection method has significant limitations: because raw manure is often highly viscous, with uneven distribution of fibers and solid particles, and may contain clumps, direct entry into the extrusion chamber easily leads to accumulation or blockage along the conveying path; resulting in uneven extrusion of the material by the screw blades.

[0003] Therefore, this utility model proposes a high-efficiency dry-wet separation device for livestock manure to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency dry-wet separation device for livestock and poultry manure, which can solve the above-mentioned technical problems.

The premixing cover is provided with a guide frame that communicates with the connecting cover. A premixing shaft is rotatably mounted on the premixing cover via a bearing. The premixing shaft is connected to a reducer via the transmission mechanism.

[0010] The premixed hood is provided with two sets of radial plates, each set of radial plates consists of two pieces, and two symmetrical mixing plates are arranged between the two pieces. The angle between the mixing plates and the radial plates is set to be more than 30°.

[0011] A feed hopper is provided above the premix hood.

[0012] Preferably, the transmission mechanism includes a pulley set and a gear set. The gear set includes a main gear and a secondary gear meshing with it.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figure 1-5 As shown, a high-efficiency dry-wet separation device for livestock and poultry manure includes a support base 1 and a bottom cover base 2 disposed on the support base 1. A main shaft 3 is rotatably mounted on the bottom cover base 2 via bearings. A spiral blade 4 is disposed on the main shaft 3 and located inside the bottom cover base 2. An upper cover base 5 for covering the spiral blade 4 is detachably mounted on the bottom cover base 2. A connecting cover 6 is detachably mounted on the feed side of the bottom cover base 2 and the upper cover base 5. A premixing component is disposed on the connecting cover 6. The spiral blade 4, the bottom cover base 2, and the upper cover base 5 are divided into three parts: a first feed section, a second extrusion section, and a third stable output section. The connecting cover 6 corresponds to the first feed end.

[0027] A reducer 15 for driving the main shaft 3 and the premixing component is installed on the side of the base 2 corresponding to the premixing component. The reducer 15 is connected to the drive motor 16 installed on itself. A controller 17 for controlling the drive motor 16 is installed on the support 1. The reducer 15 is a dual-output shaft reducer, and the drive motor 16 is a three-phase asynchronous motor with a rated power between 5.5kW and 7.5kW to adapt to the working medium of viscous and easily agglomerated manure and the load fluctuation caused by the segmented extrusion of the spiral blades. The rated speed of the motor is selected as a four-pole motor of 1440r / min or 1460r / min so that the reducer can achieve a suitable low-speed and high-torque output of the main shaft spiral blades (usually adjustable to the range of 10-30r / min). At the same time, the speed is increased to the high-speed dispersing speed required by the premixing shaft 9 through the transmission mechanism (calculated with a gear transmission ratio of 1:5 or higher, the speed of the premixing shaft can reach more than 70r / min).

[0028] The bottom surface of the support base 1 is provided with a drain pipe 18, which passes through the support base 1 and corresponds to the inner bottom surface of the bottom cover 2. The bottom surface of the bottom cover 2 is set as a grid structure.

[0029] As an optional implementation, the premixing component includes a premixing hood 7 and a transmission mechanism. The premixing hood 7 is disposed above the base hood 2 at a offset position. The premixing hood 7 is provided with a guide frame 8 that communicates with the connecting hood 6. A premixing shaft 9 is rotatably mounted on the premixing hood 7 via a bearing. The premixing shaft 9 is connected to the reducer 15 via the transmission mechanism. In this way, the feces and sludge in the premixing hood 7 can slide down through the guide frame 8 to the corresponding spiral blade 4 of the connecting hood 6, and then be conveyed and squeezed for dewatering by the spiral blade 4.

[0030] The premixing hood 7 is provided with two sets of radial plates 91, each set of radial plates 91 consists of two pieces, and two symmetrical mixing plates 92 are provided between the two pieces. The angle between the mixing plates 92 and the radial plates 91 is set to more than 30° to improve the mixing and dispersing effect of the feces when the mixing plates 92 rotate.

[0031] A feed hopper 71 is provided above the premix hood 7 to facilitate feeding materials into the premix hood 7.

[0032] See attached document Figure 4 and attached Figure 5 The transmission mechanism includes a pulley set 12 and a gear set 13. The gear set 13 includes a main gear 13a and a secondary gear 13b meshing with it. The secondary gear 13b is keyed and installed on one side of the premixing shaft 9. The main gear 13a is keyed and installed on one side of the stabilizing shaft 11a. This allows the stabilizing shaft 11a to rotate, thereby driving the main gear 13a to rotate. This causes the main gear 13a to mesh and drive the secondary gear 13b and the mixing plate 92 on the premixing shaft 9 to rotate, thereby breaking up the feces and sludge in the premixing hood 7.

[0033] See attached document Figure 3 The premixed cover 7 is mounted on the support frame 10. Two bearing seats 11 are detachably mounted on the side of the support frame 10. The two bearing seats 11 are rotatably engaged with the main shaft 3 and the stabilizing shaft 11a respectively. A shielding cover 14 for shielding the gear set 13 and the pulley set 12 is mounted on the side of the support frame 10 by screws. In this way, the shielding cover 14 can shield the gear set 13. At the same time, the bearing seats 11 on the support frame 10 provide stable support for the side of the main shaft 3 and the stabilizing shaft 11a on which the gear set 13 is mounted, thereby improving the stability of the main shaft 3 and the stabilizing shaft 11a when they rotate.

[0034] Furthermore, the pulley assembly 12 is disposed between the stabilizing shaft 11a and another output shaft on the reducer 15, and the pulley assembly 12 and the main gear 13a are symmetrically arranged with respect to the bearing axis. The pulley assembly 12 adopts the combination of pulley and transmission belt in the prior art.

[0035] Furthermore, the transmission ratio between the main gear 13a and the secondary gear 13b is set to 1:5 or higher to increase the rotational speed of the mixing plate 92 on the premixing shaft 9, thereby enhancing the dispersing effect of fecal matter in the premixing hood 7.

[0036] Using the above structure, firstly, the livestock and poultry manure to be treated is fed into the premixing hood 7 through the feed hopper 71 above the premixing hood 7; the drive motor 16 is started by the controller 17, and the power is synchronously transmitted to the main shaft 3 and the transmission mechanism through the reducer 15. On the one hand, the premixing shaft 9 drives the mixing plate 92 on it to rotate at high speed in the premixing hood 7, which strongly disperses the manure, breaks up the clumps, and achieves uniform mixing. On the other hand, the main shaft 3 drives the spiral blades 4 to rotate. After premixing and homogenization, the manure is guided by the mixing plate 92 and its own gravity, and slides into the connecting hood 6 through the guide frame 8 and enters the first feeding section of the spiral blades 4; the spiral blades 4 continue to rotate, and smoothly convey the material to the second feeding section. In the extrusion section, the material is subjected to gradually increasing axial extrusion and radial constraint. Under pressure, the free liquid in the sewage is squeezed out through the grid structure at the bottom of the bottom cover 2 and discharged through the drain pipe 18. The dehydrated solid material is then pushed to the third stable output section, where it is further compacted and its shape is kept stable before finally being discharged from the end of the device. During this process, the detachable bottom cover 2, upper cover 5, and connecting cover 6 facilitate thorough cleaning of the interior after shutdown, while the support frame 10, bearing seat 11, and shield 14 provide a stable operating environment and safety protection for the transmission system, thereby ensuring that the device can continuously and efficiently complete the dry and wet separation of sewage.

The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art.
