Description

Technical Field

[0001] The invention relates to material dehydration equipment, in particular to an organic waste dehydration device. Background Art

[0002] Organic waste dewatering equipment, as core equipment for the reduction and resource utilization of high-moisture organic materials, is widely used in the dewatering treatment of organic waste such as sludge, fruit and vegetable by-products, food waste, and livestock and poultry manure. Currently, commonly used organic waste dewatering devices are mainly divided into four categories based on their working principles: mechanical extrusion, which achieves solid-liquid separation through screw extrusion or roller pressure, is suitable for high-viscosity materials but is prone to clogging; centrifugal dewatering, which relies on centrifugal force to separate thin suspensions, has a large processing capacity but high energy consumption; filtration, which uses a filter to intercept solids and is sensitive to changes in the solid content of the material; and compression, which further reduces the moisture content through high-pressure compression, but the equipment is complex and the processing efficiency is limited. Although various types of dehydration devices have advantages in specific scenarios, they generally face two major technical bottlenecks: First, the single action mode leads to limited material adaptability, making it difficult to balance dehydration efficiency and effect. For example, centrifugal equipment has insufficient processing capacity for high-viscosity materials, and extrusion equipment is prone to slippage when processing thin materials; second, the equipment has a complex structure, high manufacturing cost, large footprint, and strict installation conditions, which limits its promotion and application in small and medium-scale scenarios and diversified material processing.

DETAILED DESCRIPTION

[0038] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figure 1 、 Figure 2As shown, the present invention discloses an organic waste dehydration device, which includes a body 5 on which are mounted components such as a centrifugal cylinder 11, a pressure head 8, a material feeding and discharging mechanism, and a control system.

[0040] See Figure 1-Figure 3 As shown, the centrifugal cylinder 11 is a vertical structure, which is rotatably fixed on the body 5 and is connected to a power device 1. The centrifugal cylinder 11 can rotate horizontally at high speed under the drive of the power device 1; the centrifugal cylinder 11 includes an outer cylinder 111 and an inner cylinder 112, the outer cylinder 111 and the inner cylinder 112 are fixedly connected and an interlayer space is formed between the two; the wall of the inner cylinder 112 is evenly provided with filter holes, and the inner wall of the inner cylinder 112 is lined with a filter cloth 113. The cavity of the inner cylinder 112 is divided into a cylindrical area 116 and a truncated cone area 117 distributed up and down according to the shape characteristics. The cylindrical area 111 is fixedly connected to the inner cylinder 112 and an interlayer space is formed between the two. 16 is cylindrical, the frustum area 117 is frustum-shaped and the inner diameter increases gradually from bottom to top; the bottom of the outer cylinder 111 is provided with a drainage channel 114 communicating with the interlayer space, and the drainage channel 114 is connected to an air intake pipe 15 and a drainage pipe 13 through a rotary joint 14; the drainage pipe 13 is used to discharge the filtrate in the interlayer space, and the air intake pipe 15 is connected to a high-pressure gas source equipment such as an air pump to fill the interlayer space with high-pressure gas; in order to avoid mutual influence between the air intake pipe 15 and the drainage pipe 13 during operation, an electric control valve 17 is installed on the air intake pipe 15 and the drainage pipe 13 respectively.

[0041] See Figure 1-Figure 5 and Figure 12 As shown, the pressure head 8 is driven by the lifting mechanism 6 to move vertically. The lifting mechanism 6 is a linear driving mechanism such as a cylinder, an oil cylinder and an electric cylinder, which is installed and fixed on the body 5; the pressure head 8 is divided into a cylindrical part 804 and a frustum part 805 distributed up and down according to the shape characteristics. The cylindrical part 804 is cylindrical, and the frustum part 805 is frustum-shaped and the outer diameter increases from bottom to top. The outside of the frustum part 805 is provided with a rubber sleeve 802 that fits tightly therewith; the rubber sleeve 802 is made of elastic material such as rubber, is in a conical shell shape and is only provided with an opening at the upper end. The upper end of the rubber sleeve 802 is sealed and fixedly connected to the pressure head 8; the outside of the pressure head 8 A pressure supply joint 7 for connecting to the pressure device is provided, and a pressure supply channel 806 is opened inside the pressure head 8, and the pressure supply joint 7 is communicated with the inner side of the rubber sleeve 802 through the pressure supply channel 806; thereby, the pressure device can fill the inner side of the rubber sleeve 802 with a high-pressure medium such as gas or liquid; when the pressure head 8 moves downward, the cylindrical portion 804 can enter the cylindrical area 116 of the inner cylinder 112 and the two are sealed together, and at the same time, the rubber sleeve 802 enters the conical area 117 of the inner cylinder 112 along with the conical portion 805, and there is a gap between the rubber sleeve 802 and the conical area 117 for accommodating filter residue; the outer wall of the rubber sleeve 802 is provided with an anti-slip structure.

[0042] See Figure 1 、 Figure 6-Figure 9 As shown, the feeding and discharging mechanism includes a feeding pipe 3 and a sliding plate 9 supported and fixed by a rotating platform 2; the rotating platform 2 is installed on the machine body 5 and is located on one side of the centrifugal cylinder 11; one end of the feeding pipe 3 is the feeding end 301, and the other end is the discharging end 302, the port of the discharging end 302 is facing downward, and the sliding plate 9 is an inclined and smooth flat plate so that the material can slide down based on gravity; the feeding and discharging device has two workstations that can be switched by rotation, one of which is the feeding and discharging workstation. In this workstation state, the sliding plate 9 is located directly below the pressure head 8, and the output end of the feeding pipe 3 is located above the barrel mouth of the inner cylinder 112. The second is the deflection workstation. In this workstation state, the feeding and discharging mechanism as a whole is located on one side of the pressure head 8 and the centrifugal cylinder 11, thereby not posing a spatial obstacle to the movement of the pressure head 8.

[0043] The control system can control the working states of the power device 1, the lifting mechanism 6 and the rotating platform 2, so that the various components in the equipment can operate in coordination and realize the automatic dehydration treatment of the material.

[0044] The use method and working principle of the organic waste dehydration device are as follows:

[0045] Feed:

[0046] like Figure 10 As shown, the feeding and discharging mechanism is shifted to the feeding and discharging station, and the material to be dehydrated is fed into the centrifugal drum 11 through the feeding pipe 3;

[0047] Centrifugal dehydration:

[0048] The centrifugal drum 11 rotates at high speed to centrifuge the material, so that the free water in the material is quickly separated. The separated filtrate is collected in the interlayer space between the outer drum 111 and the inner drum 112 and discharged through the drainage pipe 13, thereby performing preliminary dehydration of the material with high water content.

[0049] One-time pressurization:

[0050] like Figure 11 、 Figure 12As shown, the feeding and discharging mechanism shifts to the deflection position, and the lifting mechanism 6 drives the pressure head 8 to move downward, so that the rubber sleeve 802 enters the conical area 117 of the inner cylinder 112 along with the conical portion 805, and the cylindrical portion 804 is sealed with the cylindrical area 116 of the inner cylinder 112 to block the upper end of the inner cylinder 112. As the pressure head 8 slowly moves downward, the internal cavity of the inner cylinder 112 will be gradually compressed, and the material will be efficiently dehydrated under high pressure. As the moisture content decreases, the filter residue will gradually take shape in the gap between the rubber sleeve 802 and the conical area 117. In practical applications, based on the currently mature and commonly used automatic control technology, the downward resistance or position of the pressure head 8 can be monitored to intelligently control the one-time pressurization process.

[0051] Secondary pressurization:

[0052] like Figure 11 、 Figure 13 As shown, a high-pressure medium is filled into the rubber sleeve 802 by a pressure device. The rubber sleeve 802 transmits the high pressure inside to the filter residue outside it by its own deformation, thereby further pressurizing the filter residue. Since the pressure distribution inside the rubber sleeve 802 is uniform, the filter residue at different positions can achieve an isostatic pressing effect, compensating for the disadvantage that the pressure on the local filter residue is weak during the first pressurization process due to its position, thereby improving the dehydration effect. As the moisture content decreases, the formed filter residue will become more dense.

[0053] Extraction residue:

[0054] See Figure 14 As shown, after the secondary pressurization is completed, the high-pressure gas source device fills the interlayer space with high-pressure gas through the air inlet pipe 15. The high-pressure gas will apply pressure to the filter residue on the side where the filter cloth 113 is located, thereby reducing the bonding force between the residue and the filter cloth 113; accordingly, while the high-pressure gas is filled into the interlayer space, the pressure device can simultaneously reduce the pressure in the rubber sleeve 802, causing the rubber sleeve 802 to shrink slightly, thereby facilitating the separation of the filter residue from the filter cloth 113; thereafter, the pressure head 8 is driven by the lifting mechanism 6 to move upward, and the formed and dense filter residue is extracted from the inner cavity of the inner cylinder 112. The anti-slip structure provided on the outer wall of the rubber sleeve 802 can effectively prevent the filter residue from slipping off the rubber sleeve 802;

[0055] Discharge:

[0056] like Figure 10 As shown, the feeding and discharging mechanism is shifted to the feeding and discharging station, and the pressure device adjusts the pressure of the pressure medium to make the rubber sleeve 802 expand or contract. As the rubber sleeve 802 deforms, the filter residue will fall off the rubber sleeve 802 and be discharged through the sliding plate 9, thereby completing the dehydration process. Since both feeding and discharging need to be completed by the feeding and discharging mechanism at the feeding and discharging station, feeding and discharging can be operated synchronously to improve processing efficiency.

[0057] See Figure 1-Figure 3 As shown, during the operation of the organic waste dehydration device of the present invention, when the pressure head 8 applies pressure to the material, the centrifugal cylinder 11 needs to bear a large load. Therefore, the centrifugal cylinder 11 has high requirements for structural stability. In order to better meet this technical requirement, it is preferred;

[0058] The upper and lower ends of the outer cylinder 111 and the inner cylinder 112 are sealed and fixedly connected;

[0059] A downwardly extending vertical shaft 115 is fixed to the lower end of the outer cylinder 111, and a shaft seat 12 is fixed to the body 5. The vertical shaft 115 is rotatably connected to the shaft seat 12, thereby providing support for the entire centrifugal cylinder 11; the rotary joint 14 is fixed to the lower end of the vertical shaft 115, and the drainage channel 114 passes through the vertical shaft 115 to connect the rotary joint 14 with the interlayer space; a driven wheel 16 is fixed to the vertical shaft 115, and the driven wheel 16 is transmission-connected to the power device 1 based on gear meshing transmission or flexible transmission.

[0060] See Figure 1 、 Figure 6-Figure 8 As shown, during the operation of the organic waste dehydration device of the present invention, the centrifugal drum 11 performs centrifugal dehydration on the material by high-speed rotation. In order to prevent the material from spilling out of the drum mouth due to high-speed rotation, it is preferred that:

[0061] The feeding and discharging mechanism also includes a cylinder cover 10 supported and fixed by the rotating platform 2, and the feeding pipe 3 is located on the upper side of the cylinder cover 10, and the output end of the feeding pipe 3 passes through the center of the cylinder cover 10; when the feeding and discharging mechanism is in the feeding and discharging position, the cylinder cover 10 is located on the upper side of the cylinder mouth of the centrifugal cylinder 11; thus, during the centrifugal dehydration process, the feeding and discharging mechanism stays in the feeding and discharging position, and the cylinder cover 10 can effectively prevent the material from spilling out of the centrifugal cylinder 11.

[0062] See Figure 4 、 Figure 5 、 Figure 12 As shown, preferably, the pressure head 8 has the following technical features:

[0063] The pressure head 8 is hollow inside and has a shell structure to reduce its own weight, reduce the workload of the lifting mechanism, save material costs, and also help reduce the process difficulty of opening the pressure supply channel 806;

[0064] The cone portion 805 of the pressure head 8 has the same taper as the cone area 117 of the inner cylinder 112;

[0065] The lifting mechanism includes a lifting rod 601 that can move up and down. The upper end of the pressure head 8 is fixedly connected to the lifting rod 601. The pressure supply connector 7 is fixed to one side of the lifting rod 601. The pressure supply channel 806 passes through the interior of the lifting rod 601 to connect the pressure supply connector 7 with the inner side of the rubber sleeve 802.

[0066] The upper end of the rubber sleeve 802 is provided with an integrated flange edge 803, and the flange edge 803 is sealed and fixedly connected to the lower side of the cylindrical portion 804; when the cylindrical portion 804 is located in the cylindrical area 116, the flange edge 803 is sealed and matched with the cylindrical area 116; thus, there is no need to provide an additional sealing ring on the cylindrical portion 804 to achieve sealing cooperation with the cylindrical area 116.

[0067] In the structure of the organic waste dehydration device of the present invention, the outer wall of the rubber sleeve 802 is provided with an anti-slip structure to prevent the filter residue from slipping off the rubber sleeve 802 during the extraction process. Based on the intention of this setting, the anti-slip structure can be a rough surface, or it can be a protrusion or pit provided on the outer wall of the rubber sleeve 802, thereby increasing the frictional resistance between the rubber sleeve 802 and the filter residue, thereby preventing the filter residue from falling off. A more preferred implementation structure is:

[0068] See Figure 4 、 Figure 5 As shown, the anti-slip structure includes a plurality of anti-slip portions 801 distributed in sequence up and down, and the anti-slip portion 801 is a groove or a convex rib extending along the outer wall of the rubber sleeve 802; thus, when extracting the filter residue, the filter residue is supported by the anti-slip portion 801 and is not easy to slip off the rubber sleeve 802, and the outer wall of the rubber sleeve 802 except the anti-slip portion 801 can adopt a smooth design to ensure that the filter residue can be relatively completely detached from the rubber sleeve 802 and is not easy to adhere to and remain on the side wall of the rubber sleeve 802.

[0069] In the structure of the organic waste dehydration device of the present invention, the feed end 301 of the feed pipe 3 is used to input the material to be dehydrated. In actual use, the feed end 301 is usually connected to the hopper 4 or a container for storing the material, and may also be connected to a pretreatment device for stirring or crushing the material. In order to ensure the stability of the connection between the feed end 301 of the feed pipe 3 and other components or equipment, it is preferred that:

[0070] like Figure 8 As shown, the central axis of the feed end 301 of the conveying pipe 3 coincides with the rotation axis of the rotating platform 2; thus, when the rotating platform 2 rotates, the position of the feed end 301 does not change, that is, it is not affected by changes in the position of the feeding and discharging mechanism, so that the feed end 301 can cooperate with other equipment more stably.

[0071] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

[0072] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
