Description

Technical Field

[0001] This utility model relates to a vacuum feeding device for vitamin E, belonging to the technical field of vacuum feeding equipment. Background Technology

[0002] Vitamin E, also known as tocopherol or gestational oleoresin, is one of the most important antioxidants. It is soluble in organic solvents such as fats and ethanol, but insoluble in water. It is stable to heat and acids, but unstable to alkalis. It is sensitive to oxygen, but not to heat, although its activity is significantly reduced during frying. It is found in cooking oils, fruits, vegetables, and grains. Vitamin E exists in eight fat-soluble forms and is commonly used in creams and lotions because it is believed to promote skin healing and reduce scarring after burns. During production, the raw material needs to be fed into processing equipment.

[0003] Application CN202220834582.3 discloses a vacuum powder feeder, including a vortex air pump and a hopper. A back-blowing device is fixedly connected to the upper end of the hopper, and a three-way pipe is fixedly connected to the outlet of the back-blowing device. One end of the three-way pipe is fixedly connected to a first solenoid valve, and the other end is fixedly connected to a second solenoid valve. A gas distribution ring is fixedly embedded in the upper surface inside the hopper. A scraper is symmetrically and movable inside the hopper, and a collection frame is symmetrically embedded in the outer surface of the hopper. This invention can automatically scrape off powder adhering to the inner wall of the hopper when absorbing moist powder, preventing powder accumulation on the inner wall after prolonged use, making it easy to clean. It also enables the scraper to self-clean, and prevents powder adhering to the inner wall of the hopper from mixing with subsequently absorbed powder, maintaining powder purity.

[0004] However, the device still has the following problem: it needs to be stopped when backflushing to remove material from the filter element, and cannot work continuously.

[0005] Therefore, this utility model proposes a new solution. Utility Model Content

[0006] The main purpose of this invention is to address the shortcomings of the above-mentioned devices, which require shutdown and cannot operate continuously when backflushing to remove material from the filter element, and to provide a vacuum feeding device for vitamin E.

[0007] The objective of this utility model can be achieved by adopting the following technical solution:

[0008] A vacuum feeding device for vitamin E includes a vacuum pump and a hopper. A connecting air pipe connects the vacuum pump and the hopper. A partition is connected to the middle of the hopper, and multiple filter elements are installed on the partition. The multiple filter elements are arranged in two groups. A backflush device is provided above the hopper. The air outlet of the backflush device is connected to a three-way pipe. Solenoid valves are installed on the two branches of the three-way pipe. The two branches of the three-way pipe are connected to air boxes through corrugated pipes. Multiple air outlets corresponding to the filter elements are connected to the bottom of the air boxes. Electric telescopic rods installed on the hopper are respectively connected to the top of the two air boxes.

[0009] Preferably, the top of the hopper is bolted to a top cover, and the electric telescopic rod is installed at the bottom of the top cover.

[0010] Preferably, a discharge pipe is fixedly connected to the bottom end of the hopper, and a valve is installed on the discharge pipe.

[0011] Preferably, a feed pipe is connected to the outer wall of the hopper.

[0012] Preferably, one end of the feed pipe is connected to a suction pipe via a flexible hose.

[0013] Preferably, the bottom of the hopper and the bottom of the vacuum pump are connected to a base plate, and the bottom of the base plate is equipped with casters.

[0014] Preferably, the bottom of the hopper is connected to a support frame installed on the top of the base plate.

[0015] Preferably, a sealing ring is fixedly connected to the top of the partition, and a sealing gasket is connected to the middle of the sealing ring.

[0016] Preferably, the partition plate is provided with mounting holes that mate with the filter element.

[0017] Preferably, an air outlet pipe is fixedly connected to the outer wall of the hopper and is interconnected with the connecting air pipe, and the air outlet pipe is located above the partition.

[0018] The beneficial technical effects of this utility model are as follows: According to the vacuum feeding device for Vitamin E of this utility model, multiple filter elements are divided into two groups, and two air boxes can cover the two groups of filter elements respectively. During use, one group of filter elements can operate independently. Therefore, during material extraction, the air box on one group of filter elements is raised by the electric telescopic rod to ensure material extraction, while the air box on the other group of filter elements is lowered by the electric telescopic rod to block the filter element. At this time, the corresponding solenoid valve is opened, and the back-blowing device back-blowing the filter element through the air outlet at the bottom of the air box removes the blocked material. Alternating cleaning of the two groups of filter elements ensures continuous, uninterrupted operation. Furthermore, the arrangement of two groups of filter elements and two air boxes allows for selection of simultaneous operation of both groups of filter elements or single-group operation depending on the material extraction situation, meeting various usage requirements.

The top cover 13 is bolted to the hopper 2 for easy disassembly and maintenance. The hose 16 and the material extraction pipe 17 facilitate material extraction by personnel. The casters 19 allow for movement. The sealing ring 20 and the sealing gasket 21 ensure airtightness when the air box 10 is pressed down.

[0029] In this embodiment, as Figures 1-6As shown, the working process of the vacuum feeding device for vitamin E provided in this embodiment is as follows:

[0030] Step 1: During normal use, keep one set of filter elements 5 working. At this time, the air box 10 at the top of one set of filter elements 5 is raised under the action of the electric telescopic rod 12, and the air box 10 at the top of the other set of filter elements 5 is pressed down on the sealing ring 20 and sealing gasket 21 under the action of the electric telescopic rod 12 to keep them sealed.

The back-blowing device 6 back-blowing the filter element 5 through the air outlet 11 at the bottom of the air box 10 to clear the blockage. At the same time, the other air box 10 is raised to ensure normal operation.

[0032] Step 3: In case of emergency, both air boxes 10 can be raised at the same time to make all filter elements 5 work at the same time and ensure material extraction.

[0033] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
