Abstract
Description
Technical Field
[0001] This utility model belongs to the field of loquat production, and in particular relates to a multi-stage purification and fine filtration device. Background Technology
[0002] In the loquat processing industry, juice filtration is a core process that determines product quality and market competitiveness. As consumers' demands for the quality of loquat beverages and processed foods continue to rise, the shortcomings of existing filtration technologies are becoming increasingly apparent.
[0003] Low filtration efficiency and clogging issues: Traditional single-stage filtration equipment uses a static filter structure. When liquid flows through, impurities tend to concentrate and adhere to local areas of the filter, leading to rapid clogging and frequent shutdowns for cleaning, which seriously affects production efficiency. For example, when processing loquat juice with high fiber content, pulp residue and pectin-like substances easily form a filter cake layer on the filter surface. Furthermore, a single filtration stage cannot simultaneously remove impurities of different particle sizes (such as fruit pulp particles, cell wall fragments, and colloidal substances), resulting in fine suspended matter remaining in the final product, affecting the clarity and taste of the beverage.
[0004] Poor backwashing effect: Traditional equipment backwashing systems mostly use fixed-point spraying or static rinsing methods, which are difficult to cover the entire surface of the filter screen, and residual impurities are not thoroughly cleaned;
[0005] Therefore, a multi-stage purification and filtration device is needed to solve the above problems. Utility Model Content
[0006] The purpose of this utility model embodiment is to provide a multi-stage purification and fine filtration device to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A multi-stage purification and fine filtration device includes a purification shell, a drive component, and a filter component. The purification shell includes an outer shell, one side of which is connected to an inlet, an outlet, a first drain pipe, and a second drain pipe. The outer shell has a first cavity, a second cavity, and a third cavity.
[0009] The driving component includes a fixed housing, which is fixedly connected to the upper surface of the outer shell. A motor is connected inside the fixed housing, and the output shaft of the motor is connected to a first gear. The first gear meshes with a second gear.
[0010] The filter element includes a first filter cylinder, the upper part of which is rotatably connected to the outer shell via a third bearing, the lower part of which is rotatably connected to the outer shell via a fourth bearing, the top end of which is connected to a second gear, the bottom end of which is fixedly connected to a second filter cylinder, the lower part of which is rotatably connected to the outer shell via a fifth bearing, and the bottom of which has several through slots.
[0011] A further technical solution also includes a backwashing assembly, which includes a water supply tank fixedly connected to one side of the outer casing. The water supply tank is fixedly connected to one end of a water pipe, which is fixedly connected inside the fixed casing. The water pipe is rotatably connected inside the first filter cartridge via a first bearing and a second bearing. The bottom end of the water pipe is fixedly connected to the outer casing via a connecting rod. Several flushing valves are provided on one side of the water pipe.
[0012] In a further technical solution, the flushing valve is inclined and is configured as a one-way valve.
[0013] In a further technical solution, both the first gear and the second gear are located between the outer casing and the fixed casing.
[0014] In a further technical solution, the first cavity is connected to the feed inlet and the first drain outlet, the second cavity is connected to the second drain pipe, and the third cavity is connected to the discharge outlet.
[0015] In a further technical solution, the first filter cartridge is connected to the second cavity through several through slots, which are arranged in a circumferential array.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This invention controls the motor to operate, causing the filter element to rotate. The rotating first and second filter cylinders can evenly filter the liquid, ensuring not only the utilization rate of the filter element but also improving the filtration and purification quality. Furthermore, impurities in the liquid are less likely to concentrate and adhere to a certain position on the filter element, making it less prone to clogging. In addition, because the liquid flows from the outside to the inside during the initial and secondary fine filtration processes, impurities in the liquid are filtered onto the outer surface of the filter element, facilitating subsequent backwashing.
[0018] In this invention, after the equipment is used, the water supply tank is activated. The cleaning solution stored in the water supply tank is sprayed through water pipes onto the inner surfaces of the first and second filter cylinders via several inclined flushing valves. During this process, the filter elements rotate synchronously under the action of the rotating second gear. The sprayed cleaning solution passes through the first and second filter cylinders, thereby washing away the impurities attached to the outer surfaces of the first and second filter cylinders. The washed-off impurities move to the bottom of the first and second cavities. The first and second drain pipes are then opened, allowing the washed-off impurities to be discharged through the first and second drain pipes. By simply controlling the water supply tank and the motor, the rotating first and second filter cylinders can be backwashed simultaneously without any dead angles, and the cleaning is rapid.
[0019] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

The purification shell 1 includes an outer shell 11. One side of the outer shell 11 is connected to an inlet 12, a discharge port 13, a first drain pipe 17, and a second drain pipe 18. The outer shell 11 has a first cavity 14, a second cavity 15, and a third cavity 16. The first cavity 14 is connected to the inlet 12 and the first drain port, the second cavity 15 is connected to the second drain pipe 18, and the third cavity 16 is connected to the discharge port 13.
[0028] The driving component 2 includes a fixed housing 21, which is fixedly connected to the upper surface of the outer housing 11. A motor 22 is connected inside the fixed housing 21. The output shaft of the motor 22 is connected to a first gear 23. The first gear 23 meshes with a second gear 24. The first gear 23 and the second gear 24 are both located between the outer housing 11 and the fixed housing 21.
[0029] The filter element 3 includes a first filter cylinder 31. The upper part of the first filter cylinder 31 is rotatably connected to the outer shell 11 via a third bearing 5, and the lower part of the first filter cylinder 31 is rotatably connected to the outer shell 11 via a fourth bearing 6. The top end of the first filter cylinder 31 is connected to a second gear 24, and the bottom end of the first filter cylinder 31 is fixedly connected to a second filter cylinder 33. The lower part of the second filter cylinder 33 is rotatably connected to the outer shell 11 via a fifth bearing 7. The bottom of the first filter cylinder 31 is provided with a plurality of through grooves 32, and the first filter cylinder 31 is connected to the second cavity 15 through the plurality of through grooves 32. The plurality of through grooves 32 are arranged in a circumferential array.
[0030] In this embodiment, when the device needs to be used, the first drain pipe 17 and the second drain pipe 18 are controlled to close.
[0031] The control motor 22 is set to work. The motor 22 is a geared motor. The working motor 22 drives the first gear 23 to rotate. The rotating first gear 23 drives the second gear 24 to rotate. The rotating second gear 24 drives the filter element 3 to rotate.
[0032] Loquat liquid is introduced into the outer shell 11 through the feed inlet 12 at a certain pressure. The liquid flows into the first cavity 14 and passes through the first filter cylinder 31 in the first cavity 14, so that the liquid enters the first filter cylinder 31 and the liquid completes the preliminary fine filtration operation.
[0033] The liquid entering the first filter cylinder 31 moves to the second cavity 15 through the through groove 32 at the bottom of the first filter cylinder 31. Then, the liquid in the second cavity 15 passes through the second filter cylinder 33 to complete the second fine filtration. The liquid entering the second filter cylinder 33 flows into the third cavity 16 from its bottom and is discharged through the discharge port 13.
[0034] Example 2
[0035] The difference between this embodiment and embodiment 1 is that it also includes a backwashing assembly 4. The backwashing assembly 4 includes a water supply tank 41, which is fixedly connected to one side of the outer shell 11. The water supply tank 41 is fixedly connected to one end of a water pipe 42, which is fixedly connected inside the fixed shell 21.

The bottom end of the water pipe 42 is fixedly connected to the outer shell 11 through a connecting rod 45. Several flushing valves 46 are provided on one side of the water pipe 42.
[0036] The flushing valve 46 is set at an angle and is a one-way valve.
[0037] In this embodiment, after the device is used, the water supply tank 41 is activated. The cleaning solution stored in the water supply tank 41 is sprayed through the water pipe 42 from several inclined flushing valves 46 onto the inner surfaces of the first filter cylinder 31 and the second filter cylinder 33. During this process, the filter element 3 rotates synchronously under the action of the rotating second gear 24. The sprayed cleaning solution passes through the first filter cylinder 31 and the second filter cylinder 33, thereby washing away the impurities attached to the outer surfaces of the first filter cylinder 31 and the second filter cylinder 33. The washed-off impurities move to the bottom of the first cavity 14 and the second cavity 15. The first drain pipe 17 and the second drain pipe 18 are then opened, and the washed-off impurities can be discharged through the first drain pipe 17 and the second drain pipe 18. By simply controlling the water supply tank 41 and the motor 22 to operate, the rotating first filter cylinder 31 and the second filter cylinder 33 can be backwashed synchronously without dead angles, and the cleaning is fast.
