Description

Technical Field

[0001] This utility model relates to the field of environmental protection, particularly environmental protection equipment, and specifically to an integrated centrifugal extrusion separation device for livestock and poultry manure. Combining centrifugal and extrusion separation, this invention can effectively improve the consistency of dryness and thinness of livestock and poultry manure and enhance the efficiency of solid-liquid separation, thus possessing high application value and promising prospects. Background Art

[0002] During the livestock and poultry farming process, a large amount of excrement, namely livestock and poultry manure, is produced, mainly including pig manure, cattle manure, sheep manure, chicken manure, duck manure, etc. If livestock and poultry manure is directly accumulated, it will pollute the surrounding environment and soil. On the other hand, livestock and poultry manure contains a large amount of nutrients, such as organic matter and nutrients such as nitrogen, phosphorus, and potassium, as well as various minerals and trace elements such as calcium, magnesium, and sulfur, which can meet the needs of crop growth. Therefore, in order to meet the goals of sustainable agricultural production, energy conservation and consumption reduction, and resource recycling, it is necessary to process livestock and poultry manure and realize its resource utilization.

[0003] The first step in treating livestock and poultry manure is solid-liquid separation. Currently, the process is as follows: farmers use water washing to process livestock and poultry manure and urine, collect the manure, and use gravity to initially separate the solids and liquids. Once a certain volume has been collected, the supernatant is removed, and the precipitated solids are sent to an extrusion separation device for dehydration. The dehydration rate of the dehydrated manure can reach over 50-70%, meeting the needs of subsequent processing. The dehydrated manure contains undigested feed fiber, which, through fermentation, can be used as feed, significantly improving the economic benefits of livestock and poultry farming.

[0004] The inventors have found in practice that the livestock and poultry manure fed into the extrusion separation device has a problem of inconsistent dryness and thinness, which to some extent affects the efficiency of solid-liquid separation of manure. Therefore, a new device is urgently needed to solve the above problem. Utility Model Content

[0044] Example 1

[0045] As shown in the figure, this embodiment provides an integrated centrifugal extrusion separation device for livestock and poultry manure, comprising a support frame, a screw extrusion unit, and a centrifugal separation unit. The screw extrusion unit is mounted on the support frame and is provided with a first feed port. With this structure, the support frame provides support for the screw extrusion unit, and material entering the screw extrusion unit through the first feed port undergoes solid-liquid separation in the screw extrusion unit.

The second inner cylinder assembly is disposed within the second outer cylinder assembly and is rotatable relative to the second outer cylinder assembly. The second outer cylinder assembly is connected to a support frame, which provides support for the second outer cylinder assembly. In this embodiment, the second outer cylinder assembly includes an outer cylinder base, outer cylinder sidewalls, and an outer cylinder top cover. The outer cylinder base is disposed on the support frame, which provides support for the outer cylinder base. The outer cylinder base is located above the first feed inlet.

The second outer cylinder assembly defines an outer cylinder storage space within the second outer cylinder assembly, and an outer cylinder liquid outlet pipe is provided on the second outer cylinder assembly, communicating with the outer cylinder storage space.

[0050] The working process of the device is as follows:

[0051] (1) Initial separation

[0052] When the device is in operation, the livestock and poultry manure to be processed is fed into the inner cylinder filter intermediate body through the second top liquid inlet pipe, and the second driving device drives the inner cylinder filter intermediate body to rotate; when the inner cylinder filter intermediate body rotates at high speed, the livestock and poultry manure to be processed in the inner cylinder filter intermediate body adheres to the filter screen on the side wall of the inner cylinder under the action of centrifugal force, and the liquid in the inner cylinder passes through the mesh and enters the compartment accommodation space, and then is discharged outward through the liquid outlet pipe of the outer cylinder due to the action of the liquid's own gravity;

[0053] The remaining material attached to the filter screen on the side wall of the inner cylinder is carried by gravity through the filter screen on the side wall of the inner cylinder, the bottom cover of the inner cylinder, the liquid outlet at the bottom of the inner cylinder, and the liquid outlet pipe at the bottom of the inner cylinder, and then enters the first feed port.

[0054] (2) Extrusion separation

[0055] The material enters the spiral extrusion unit through the first feed port for extrusion to achieve solid-liquid separation. The moisture content of the processed livestock and poultry manure can meet the set requirements.

[0056] In one specific embodiment, the second drive assembly includes a second internal gear ring, a second drive gear, a second drive unit, and a second drive connecting shaft. The second internal gear ring is tubular and has several teeth disposed on its inner side that mesh with the second drive gear. The second internal gear ring and the second drive gear are each located within the outer cylinder housing. The second drive connecting shaft passes through the outer cylinder base and is rotatable relative to the outer cylinder base. A dynamic seal is employed between the second drive connecting shaft and the outer cylinder base. One end of the second drive connecting shaft is connected to the second drive unit, and the second drive gear is disposed on the other end of the second drive connecting shaft. The second drive unit drives the second drive gear to rotate via the second drive connecting shaft. The second drive gear meshes with the second internal gear ring, which is fixedly connected to the inner cylinder filter intermediate body. The second drive gear drives the inner cylinder filter intermediate body to rotate via the second internal gear ring. Furthermore, the second internal gear ring is fixedly connected to the inner cylinder bottom cover.

[0057] Preferably, the second drive assembly further includes a second drive driving wheel, a second drive driven wheel, and a second drive connecting belt. The second drive driving wheel is disposed on the output shaft of the second drive device, the second drive driven wheel is disposed on the second drive connecting shaft, and the second drive connecting belt is disposed on the second drive driving wheel and the second drive driven wheel. In one specific embodiment, the second drive device is a motor. With this structure, the second drive device sequentially drives the second drive connecting shaft and the second drive gear on the second drive connecting shaft to rotate synchronously. Based on the meshing relationship between the second drive gear and the second inner gear ring, the second inner gear ring drives the inner cylinder filter intermediate to rotate synchronously.

[0058] Furthermore, it also includes a control system, and the second driving device and the screw extrusion unit are respectively connected to the control system.

[0059] With the solution of this application, the livestock and poultry manure to be processed is initially separated by a centrifugal separation unit, resulting in a more consistent manure before being fed into the spiral extrusion unit. This improved consistency of manure fed into the spiral extrusion unit effectively improves the efficiency of solid-liquid separation. Furthermore, this structure significantly improves the efficiency of manure treatment and reduces the cost of manure treatment, which is of great significance for achieving sustainable development in the livestock and poultry farming industry.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
