Description

Technical Field

[0001] This utility model relates to the technical field of screw conveyor equipment, specifically a screw conveyor equipment for conveying oil cake residue after oil extraction. Background Technology

[0002] In the oil pressing process, the screw conveyor is a continuous mechanical device that uses rotating screw blades to transport oil cake residue horizontally, inclined or vertically. Its core function is to efficiently and stably transfer the solid residue after oil pressing, while also having sealing and flexibility to adapt to process requirements.

[0003] Oil cake residue is a product generated during oil pressing or oil extraction. It is commonly used as a raw material for feed and organic fertilizer. During the oil pressing process, conveying devices are used to transport the oil cake residue, either to re-extract it from the pressing equipment for repeated pressing or to a designated location for storage to facilitate subsequent feed production. However, when oil cake residue is used for feed, common conveying equipment is not conducive to feed pretreatment. For example, it cannot automate key steps such as crushing, mixing, or adding nutrients, resulting in low subsequent processing efficiency and difficulty in ensuring the uniformity of feed quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a screw conveyor for oil cake residue after oil extraction, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an oil cake residue auger conveying device after oil extraction, comprising a feeding bin and a conveying bin, wherein the conveying bin is inclined and includes a feeding port and a discharging port respectively opened at both ends, and the feeding port of the conveying bin is fixedly connected to the bottom end of the feeding bin, and the conveying bin is provided with a conveying component for conveying oil cake residue. The feed hopper has two chambers inside through a partition. The upper surface of the partition is equipped with a sealing component for sealing one of the chambers. A rotating rod is rotatably connected to the inner wall of one of the chambers. Multiple auxiliary feed plates distributed in a circle are fixedly connected to the circumferential surface of the rotating rod. Each auxiliary feed plate has an arc-shaped structure. Another chamber has a rotating tube rotatably connected to its inner wall. The rotating tube is connected to the rotating rod via a pulley and belt drive. Multiple circumferentially distributed crushing blades are fixedly connected to the circumferential surface of the rotating tube, and multiple circumferentially distributed nozzles are also fixedly connected to the circumferential surface of the rotating tube. A water storage chamber is formed on one side of the feed bin along its width direction, and a liquid inlet assembly is provided between the water storage chamber and the rotating tube. Another chamber has a rotating column rotatably connected to its inner wall. A lifting plate is fixedly connected to the circumference of the rotating column. The lifting plate has an arc-shaped structure and seals the bottom of the chamber. The rotating column and the rotating tube are connected by a linkage assembly.

[0006] Furthermore, the sealing assembly includes a rotating column rotatably connected to the inner wall of the feed hopper, the rotating column being located between two chambers, and a baffle fixedly connected to the circumferential surface of the rotating column, the baffle sealing one of the chambers.

[0007] The above method allows for the control of opening and closing one of the chambers by rotating the baffle through the rotating column.

[0008] Furthermore, the liquid inlet assembly includes a pump body fixedly installed on one side of the feed hopper, the water inlet end of the pump body is connected to the water storage chamber, and the output end of the pump body is connected to the rotating pipe through a hose and a rotary joint. A water inlet valve is installed on one side of the feeding hopper, and the water inlet valve is fixedly connected to the water storage chamber.

[0009] With the above scheme, the liquid inlet assembly delivers the agent in the water storage chamber to the rotating tube through the pump body, and then sprays it out through the nozzle. The setting of the hose and the rotary joint ensures the normal delivery of the agent when the rotating tube rotates, and the water inlet valve facilitates the control of the liquid in and out of the water storage chamber.

[0010] Furthermore, the linkage component includes a cam fixedly connected to one end of the rotating column, and an elastic lever fixedly installed at one end of the rotating tube, with the elastic lever in contact with the cam.

[0011] With the above scheme, the connecting components can drive the elastic lever to rotate synchronously during the rotation of the rotating tube, so that the elastic lever can contact the cam and drive the rotating column to rotate by pushing the cam. When the lifting plate on the rotating column contacts the inner wall of the corresponding chamber, the elastic lever will deform and separate from the cam. After separation, the lifting plate will open the corresponding chamber under the action of gravity.

[0012] Furthermore, the conveying assembly includes a conveying rod rotatably connected to the inner wall of the conveying chamber, an auger fixedly connected to the circumferential surface of the conveying rod, the conveying chamber having a U-shaped structure, and the auger contacting the arc-shaped surface of the conveying chamber; A servo motor is fixedly installed on one side of the conveyor bin, and the output end of the servo motor is fixedly connected to the conveyor rod.

[0013] The above scheme uses a servo motor to drive the conveying rod to rotate, which in turn causes the auger to rotate, thus realizing the conveying of oil cake residue in the conveying bin.

[0014] Furthermore, the upper surface of the conveying chamber is provided with multiple ventilation holes arranged in a matrix.

[0015] The above solution allows air to circulate in the conveying chamber, preventing the oil cake residue from deteriorating due to heat during transport, and also helps to dissipate any odors that may be produced by the oil cake residue.

[0016] Furthermore, the discharge port of the conveying bin is fixedly connected to a corrugated frame.

[0017] The above solution provides the corrugated frame with a certain degree of flexibility, allowing the length of the discharge port to be adjusted according to actual needs during material discharge, thus facilitating the transport of oil cake residue to the designated location.

[0018] Compared with the prior art, the technical solution of this utility model has the following beneficial effects: This oil cake residue auger conveyor, through the combination of the liquid inlet component, crushing blade, and nozzle structure, can add a fermentation-promoting catalyst into the crushed oil cake residue during the crushing process. The conveying component mixes the oil cake residue with the catalyst during transport. Furthermore, the device features two chambers: one for crushing the oil cake residue for use as animal feed, and the other for bulk transport of the residue. The conveying component then re-transports the residue back into the oil pressing equipment for re-pressing. A sealing component allows for adjustment and sealing of one of the chambers, facilitating use under different operating conditions. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figures 1-4 The oil cake residue conveying device in this embodiment includes a feeding bin 1 and a conveying bin 2. The conveying bin 2 is inclined and includes a feeding port 201 and a discharge port 202 opened at both ends. The feeding port 201 of the conveying bin 2 is fixedly connected to the bottom end of the feeding bin 1. The conveying bin 2 is equipped with a conveying component 3 for conveying the oil cake residue.

[0023] The feed hopper 1 has two chambers 5 formed by a partition 4. The upper surface of the partition 4 is provided with a sealing component 6 for sealing one of the chambers 5. A rotating rod 7 is rotatably connected to the inner wall of one of the chambers 5. One end of the rotating rod is fixedly connected to the output end of an external motor. Multiple auxiliary feed plates 8 are fixedly connected to the circumferential surface of the rotating rod 7. Each auxiliary feed plate 8 has an arc-shaped structure. The two chambers 5 are connected by the sealing component 6 to seal one of the chambers 5. Different subsequent operations can be performed through the two chambers 5. One chamber 5 is used for quantitative conveying of oil cake residue, and the oil cake residue is conveyed back to the oil pressing area for re-pressing through the conveying component 3. The other chamber 5 can crush the oil cake residue, and the crushed oil cake residue is conveyed to a designated location for bagging through the conveying component 3.

[0024] Another chamber 5 has a rotating tube 9 rotatably connected to its inner wall. The rotating tube 9 is connected to the rotating rod 7 via a pulley and belt drive. Multiple circumferentially distributed crushing blades 10 are fixedly connected to the circumferential surface of the rotating tube 9, and multiple circumferentially distributed nozzles 11 are also fixedly connected to the circumferential surface of the rotating tube 9. A water storage chamber 12 is formed on one side of the feed bin 1 along its width direction. A liquid inlet assembly 13 is provided between the water storage chamber 12 and the rotating tube 9. The liquid inlet assembly 13 can deliver fermentation-promoting agents, such as EM bacteria fermentation agents, into the rotating tube 9 during its rotation. The rotation of the rotating tube 9 allows the nozzles 11 to make uniform contact with the oil cake residue fragments, which facilitates the subsequent fermentation of the oil cake residue.

[0025] Another chamber 5 is rotatably connected to a rotating column 14 on its inner wall. A lifting plate 15 is fixedly connected to the circumferential surface of the rotating column 14. The lifting plate 15 has an arc-shaped structure and blocks the bottom of the chamber 5. The rotating column 14 is connected to the rotating tube 9 through a linkage component 16. The linkage component 16 can indirectly drive the lifting plate 15 to swing during the rotation of the rotating tube 9, so that the lifting plate 15 can indirectly block the adjacent chamber 5, allowing the material to be temporarily retained in the chamber 5, and enabling the multiple crushing blades 10 to crush the oil cake residue more evenly.

[0026] The sealing assembly 6 includes a rotating column 601 rotatably connected to the inner wall of the feed hopper 1. The rotating column 601 is located between two chambers 5. A baffle 602 is fixedly connected to the circumferential surface of the rotating column 601. The baffle 602 blocks one of the chambers 5. The opening and blocking of one of the chambers 5 can be controlled by rotating the rotating column 601 to drive the baffle 602 to rotate.

[0027] The liquid inlet assembly 13 includes a pump body 1301 fixedly installed on one side of the feed hopper 1. The water inlet end of the pump body 1301 is connected to the water storage chamber 12. The output end of the pump body 1301 is connected to the rotating tube 9 through a hose and a rotary joint. A water inlet valve 1302 is provided on one side of the feed hopper 1. The water inlet valve 1302 is fixedly connected to the water storage chamber 12. The liquid inlet assembly 13 delivers the agent in the water storage chamber 12 to the rotating tube 9 through the pump body 1301, and then sprays it out through the nozzle 11. The hose and rotary joint ensure the normal delivery of the agent when the rotating tube 9 rotates. The water inlet valve 1302 facilitates the control of the liquid inlet and outlet of the water storage chamber 12.

[0028] The linkage component 16 includes a cam 1601 fixedly connected to one end of the rotating column 14, and an elastic lever 1602 fixedly installed at one end of the rotating tube 9. The elastic lever 1602 contacts the cam 1601. Through the connection component, the elastic lever 1602 can be driven to rotate synchronously during the rotation of the rotating tube 9, so that the elastic lever 1602 can contact the cam 1601 and drive the rotating column 14 to rotate by pushing the cam 1601. When the lifting plate 15 on the rotating column 14 contacts the inner wall of the corresponding chamber 5, the elastic lever 1602 will deform and separate from the cam 1601. After separation, the lifting plate 15 will open the corresponding chamber 5 under the action of gravity.

[0029] The conveying assembly 3 includes a conveying rod 301 rotatably connected to the inner wall of the conveying chamber 2, and an auger 302 fixedly connected to the circumferential surface of the conveying rod 301. The conveying chamber 2 has a U-shaped structure, and the auger 302 contacts the arc-shaped surface of the conveying chamber 2. A servo motor 303 is fixedly installed on one side of the conveying chamber 2, and the output end of the servo motor 303 is fixedly connected to the conveying rod 301. The conveying assembly 3 drives the conveying rod 301 to rotate through the servo motor 303, thereby causing the auger 302 to rotate, so as to realize the conveying of oil cake residue in the conveying chamber 2.

[0030] The upper surface of the conveying chamber 2 is provided with multiple ventilation holes 17 arranged in a matrix. The ventilation holes 17 allow air to circulate inside the conveying chamber 2, preventing the oil cake residue from deteriorating due to heat during the conveying process. At the same time, they help to dissipate any odors that the oil cake residue may produce. The discharge port 202 of the conveying chamber 2 is fixedly connected to a corrugated frame 18. The corrugated frame 18 has a certain degree of flexibility, and the length of the discharge port 202 can be adjusted according to actual needs during discharge, so as to facilitate the conveying of the oil cake residue to the designated location.

[0031] The working principle of the above embodiment is as follows: When the oil cake residue is transported into the oil pressing equipment, the rotating column 601 is rotated, causing the rotating column 601 to drive the baffle 602 to block the chamber 5 used for crushing the oil cake residue. Subsequently, the external motor drives the rotating rod 7 to rotate, causing the rotating rod 7 to drive the rotating tube 9 to rotate synchronously through the belt transmission. During the rotation of the rotating rod 7, the oil cake residue can be transported in batches through the auxiliary feeding plate 8. Under the action of gravity, the oil cake residue enters the conveying chamber 2 through the feed port 201. At this time, the servo motor 303 drives the conveying rod 301 to rotate, causing the conveying rod 301 to drive the auger 302 to transport the oil cake residue, so that the oil cake residue re-enters the external oil pressing equipment through the discharge port 202 for re-oil pressing.

[0032] When the oil cake residue is used as feed, the rotating column 601 is rotated in the reverse direction, causing the baffle 602 to block the chamber 5 for batch conveying the oil cake residue. The oil cake residue will then enter the crushing chamber 5. As the rotating pipe 9 rotates, it can drive multiple crushing blades 10 to crush the oil cake residue that has entered the chamber 5. At the same time, during the crushing process, the pump body 1301 can draw the agent from the water storage chamber 12 and deliver the agent to the rotating pipe 9 through the hose and rotating structure. The agent is then sprayed into the chamber 5 from multiple nozzles 11 on the rotating pipe 9. During this process, the rotating pipe 9 can drive the elastic lever 1602 to move, causing it to contact the cam 1601. When the lifting plate 15 hits the crushing chamber... After the discharge point is blocked, the elastic lever 1602 can deform and separate from the cam 1601, so that the lifting plate 15 can be reset under the action of gravity. During the movement, the lifting plate 15 can block the crushed oil cake residue, so that the oil cake residue can be temporarily retained in the crushing chamber, thereby improving the uniformity of crushing the oil cake residue. The agent and the oil cake residue are mixed and put into the conveying chamber 2. Through the conveying of the auger 302, the crushed oil cake residue and the agent will be mixed and conveyed to the designated area, which is convenient for bagging the crushed oil cake residue. During the conveying process, the vent 17 on the conveying chamber 2 can facilitate the dissipation of heat from the oil cake residue, so that the oil cake residue can be gradually cooled during the conveying process.
