Description

Technical Field

[0001] This utility model relates to the field of grain and oil production technology, and in particular to a raw material metering device for rapeseed oil production and processing. Background Technology

[0002] Rapeseed oil, an important edible vegetable oil, is produced and processed through steps including cleaning, rolling, steaming and roasting, pressing (or solvent extraction), and refining. The pressing (or pre-pressing) process yields unrefined crude oil. Crude oil contains free fatty acids, phospholipids, gums, pigments, moisture, solid impurities, and off-flavor substances, making it unsuitable for direct consumption or meeting commercial oil standards; therefore, it must undergo subsequent refining.

[0003] The refining process typically involves multiple steps, including degumming, deacidification (alkali refining), decolorization, deodorization, and dewaxing (wintering). In these refining processes, to achieve optimal refining results and ensure the quality and stability of the final oil product, crude oil often needs to be mixed or reacted with other components (such as alkali solution, bleaching clay, deodorizing steam, and filter aids) in strict and precise proportions. Therefore, accurate metering of crude oil, as the core raw material, is one of the key aspects of the entire refining process control, directly affecting refining efficiency, product quality, production costs, and raw material utilization.

[0004] Currently, in the crude oil metering process of small and medium-sized rapeseed oil processing plants or some refining workshops, volumetric metering devices are commonly used. For example, Chinese utility model patent CN222362079U discloses a raw material metering device for rapeseed oil production and processing, which specifically discloses: "A raw material metering device for rapeseed oil production and processing includes a support frame, a hopper, a metering cylinder, a storage tank, a conveying pipe, a cover plate, and a fixing plate; the metering cylinder is connected to the support frame, the hopper is connected to the metering cylinder, the fixing plate is connected to the upper end of the metering cylinder, the fixing plate is provided with a push plate mechanism, and the push plate mechanism is provided with a feed pipe; the storage tank is provided with a filter assembly, the cover plate is connected to the upper end of the storage tank and is coaxially distributed with the storage tank, the storage tank is provided with a discharge pipe, the two ends of the conveying pipe are respectively connected to the discharge pipe and the feed pipe, and the conveying pipe is provided with a conveying pump; the fixing plate is provided with a control mechanism, which controls the push plate mechanism and the conveying pump. In this utility model, the amount of material in the metering cylinder can be adjusted as needed by the height position of the push plate in the metering cylinder, and the metering cylinder can be further adjusted by the push plate mechanism." The method of discharging raw materials directly from the metering cylinder facilitates more precise control. However, it presents the following problems: 1. Raw materials from the storage tank enter the metering cylinder through a conveying pipe. The presence of gas in the metering cylinder hinders the smooth flow of raw materials. Furthermore, the high pressure used to transport the raw materials into the metering cylinder prevents complete compression of the gas, resulting in errors in the volume of raw materials entering the metering cylinder and affecting subsequent refining quality. 2. Before the raw materials enter the metering cylinder, the position of the pusher plate needs to be adjusted by the pusher plate mechanism before the raw materials are conveyed into the metering cylinder. Finally, the pusher plate is pushed by the pusher plate mechanism to discharge the raw materials from the metering cylinder, which is time-consuming and inefficient. 3. The metering cylinder has an opening at the top, allowing dust to adhere to the side walls. When a larger volume is needed, the pusher plate moves upward, causing the dusty side walls to be below the pusher plate, which then mixes with the raw materials entering the metering cylinder, increasing the impurity content and affecting the refining effect. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a raw material metering device for rapeseed oil production and processing that can improve efficiency, reduce dust entering the metering cylinder, and more accurately measure the volume of raw materials discharged from the metering cylinder.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A raw material metering device for rapeseed oil production and processing includes a base, a storage tank fixedly installed on the base, a cylinder support fixedly installed on the base, and a metering cylinder fixedly connected to the cylinder support. A discharge pipe is fixedly installed downward at the lower end of the metering cylinder, and a discharge valve is installed at the lower end of the discharge pipe.

[0008] A feed pipe is installed between the lower end of the storage tank and the discharge pipe, and a feed valve is installed at the end of the feed pipe near the discharge pipe.

[0009] A cylinder cover is fixedly installed at the upper end of the metering cylinder. A cylinder is fixedly installed on the cylinder cover. The cylinder rod passes through the metering cylinder and a piston is fixedly installed thereon. The piston is located inside the metering cylinder and a sealing ring is fixedly installed on the piston. The sealing ring is in pressure contact with the inner wall of the metering cylinder. The cylinder cover has several air holes located on the same circumference. A cover is fixedly installed on the cylinder cover. The air holes are positioned directly opposite the cover. The cover is connected to a gas filter structure.

[0010] In this way, the storage tank contains raw material, specifically crude oil. A filter structure can be installed inside the storage tank to initially filter impurities from the crude oil. When a quantitative output of raw material is required, initially, the piston is in contact with the lower end of the metering cylinder, the discharge valve is closed, and the feed valve is opened. The cylinder drives the piston upward, and under negative pressure, the raw material in the storage tank enters the metering cylinder through the feed pipe. After the piston reaches its designated position, the required quantitative volume of raw material is dispensed. An air vent is provided to allow gas to escape between the piston and the cylinder cover during piston movement. Then, the feed valve is closed, the discharge valve is opened, and the cylinder drives the piston downward, pushing the raw material out of the metering cylinder, achieving quantitative discharge. A cover shields the air vent, preventing dust from entering through direct air contact. A gas filtration structure further filters the gas entering the cover, reducing dust and impurities entering the metering cylinder. A sealing ring is designed to press firmly against the side wall of the metering cylinder, preventing crude oil leakage or residue.

[0011] Preferably, the gas filtration structure includes a filter box fixedly installed on the outside of the metering cylinder, an opening on one side of the filter box, a frame fixedly installed on the opening side of the filter box, a filter screen fixedly installed on the frame opposite the opening, and the filter box connected to the cover via a gas pipe.

[0012] Preferably, the lower end of the piston is conical, and the inner side of the lower end of the metering cylinder is a conical opening that conforms to the shape of the piston.

[0013] Preferably, the lower end of the piston is provided with a mounting platform, and the sealing ring is connected to the mounting platform by adhesive.

[0014] Preferably, a delivery pump is installed on the feed pipe.

[0015] In summary, this raw material metering device for rapeseed oil production and processing has the advantages of improving efficiency, reducing dust entering the metering cylinder, and providing more accurate measurement of the volume of raw material discharged from the metering cylinder.

[0020] like Figure 1-3 As shown, a raw material metering device for rapeseed oil production and processing includes a base 1, a storage tank 2 fixedly installed on the base, a cylinder support 3 fixedly installed on the base, and a metering cylinder 4 fixedly connected to the cylinder support. A discharge pipe 5 is fixedly installed downward at the lower end of the metering cylinder, and a discharge valve 6 is installed at the lower end of the discharge pipe.

[0021] A feed pipe 7 is installed between the lower end of the storage tank and the discharge pipe, and a feed valve 8 is installed at the end of the feed pipe near the discharge pipe.

[0022] A cylinder cover 9 is fixedly installed at the upper end of the metering cylinder. A cylinder 10 is fixedly installed on the cylinder cover. The cylinder rod passes through the metering cylinder and a piston 11 is fixedly installed on it. The piston is located inside the metering cylinder and a sealing ring 12 is fixedly installed on it. The sealing ring is in pressure contact with the inner wall of the metering cylinder. The cylinder cover is provided with a plurality of air holes 13, which are located on the same circumference. A cover 14 is fixedly installed on the cylinder cover. The air holes are positioned directly opposite the cover. The cover is connected to a gas filter structure.

[0023] In this way, the storage tank contains raw material, specifically crude oil. A filter structure can be installed inside the storage tank to initially filter impurities from the crude oil. When a quantitative output of raw material is required, initially, the piston is in contact with the lower end of the metering cylinder, the discharge valve is closed, and the feed valve is opened. The cylinder drives the piston upward, and under negative pressure, the raw material in the storage tank enters the metering cylinder through the feed pipe. After the piston reaches its designated position, the required quantitative volume of raw material is dispensed. An air vent is provided to allow gas to escape between the piston and the cylinder cover during piston movement. Then, the feed valve is closed, the discharge valve is opened, and the cylinder drives the piston downward, pushing the raw material out of the metering cylinder, achieving quantitative discharge. A cover shields the air vent, preventing dust from entering through direct air contact. A gas filtration structure further filters the gas entering the cover, reducing dust and impurities entering the metering cylinder. A sealing ring is designed to press firmly against the side wall of the metering cylinder, preventing crude oil leakage or residue.

[0024] In implementation, the gas filtration structure includes a filter box 15 fixedly installed on the outside of the metering cylinder. An opening is provided on one side of the filter box, and a frame 16 is fixedly installed on the open side of the filter box. A filter screen 17 is fixedly installed on the frame opposite the opening. The filter box is connected to the casing via a gas pipe 18. The filter screen filters the gas entering the gas pipe, reducing impurities. The frame and filter box are fixedly connected with screws for easy disassembly and cleaning.

[0025] In practice, the lower end of the piston is conical, and the inner side of the lower end of the metering cylinder has a conical opening that mimics the shape of the piston. This conical shape and opening allow for better material discharge.

[0026] In practice, a mounting platform is provided circumferentially at the lower end of the piston, and the sealing ring is connected to the mounting platform by adhesive. The mounting platform facilitates the installation of the sealing ring and also makes it easy to use.

[0027] During implementation, a conveying pump 19 is installed on the feed pipe. The conveying pump, in conjunction with pumping the raw materials, shortens the feeding time, and, in conjunction with the cylinder driving the piston to move, better realizes the feeding of crude oil.

[0028] Specifically, it also includes a PLC controller, which is used to control the operation of the delivery pump and cylinder, making it easy to use.

[0029] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
