Description

Technical Field

[0001] This utility model relates to the field of pet nutrient solution production technology, and in particular to a membrane separation device. Background Technology

[0002] Pet nutritional supplements are dietary additives designed to meet the specific nutritional needs of pets. They are mainly used to compensate for nutritional deficiencies in daily diets or to provide nutritional fortification during special physiological stages. They are used to provide multi-dimensional nutritional support for senior dogs and cats, adult dogs and cats, and newborn puppies with weaker immune systems, establishing a comprehensive support to build a strong health barrier. At the same time, they provide essential nutritional supplements for each growth stage of dogs and cats, achieving comprehensive nutritional support and improving immunity.

[0003] Pet nutritional supplements contain various minerals, vitamins, and amino acids. The main raw materials are skimmed goat milk powder, fresh chicken, and purified water. Before being used as a raw material, goat milk needs to be separated into components such as fat and casein particles using a membrane separation device. After separation, a large amount of fat accumulates on the surface of the separation membrane, causing clogging. The existing solution is to backwash the separation membrane when clogging occurs. However, backwashing requires a long period of rinsing after shutdown to bring the separation membrane back to the standard for use, and it also generates a large amount of wastewater. The problem of needing to shut down the machine for backwashing after membrane clogging prevents continuous filtration and separation of goat milk, resulting in low production efficiency. Therefore, a membrane separation device is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a membrane separation device to solve the problem in the background art that the separation membrane needs to be shut down for backwashing after clogging, which prevents continuous filtration and separation of sheep milk and results in low production efficiency. The technical solution of this invention provides a solution that is significantly different from the prior art.

[0008] Preferably, the housing is a hollow cylindrical structure with an open top. The upper end of the positioning plate is located inside the limiting groove. Several balls are arranged inside the limiting groove. The positioning plate contacts the balls. A first sealing ring and a second sealing ring are respectively provided at the contact points between the first partition plate and the inner wall of the housing.

[0009] Preferably, the upper end of the support rod is provided with a protrusion, the lower end of the support rod extends into the interior of the slag collection bin, the protrusion is connected to the top plate screw, the brush plate is fixed to the side of the support rod, and one end of the brush plate is in contact with the surface of the filter membrane body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses a first and a second partition on the side of the membrane separation assembly to divide the space between the housing and the filter membrane body into an upper storage space and a lower storage space. When the sheep milk raw liquid enters the feeding assembly from the feed pipe, the feeding assembly rotates, causing the sheep milk raw liquid to be sprayed onto the filter membrane body from the discharge port by centrifugal force. Then, the membrane separation assembly drives the filter membrane body to rotate at high speed, causing the sheep milk raw liquid on the surface of the filter membrane body to be separated into purified liquid and filter residue by centrifugal force. The purified liquid passes through the filter membrane body into the upper storage space and is discharged from the liquid outlet, while the filter residue adheres to the filter membrane body and is swept off into the residue collection bin by the brush plate. Then, it enters the lower storage space through the through hole by centrifugal force and is discharged from the residue outlet. Compared with the method of stopping the machine for backwashing after the filter membrane body is blocked, continuous filtration and separation of sheep milk is achieved, improving production efficiency.

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

[0022] Please see Figure 1-4 In this utility model, a membrane separation device includes a housing 1, with a liquid outlet 101 and a residue outlet 102 on the side of the housing 1, a top plate 103 on the top of the housing 1, a membrane separation component 3 for purifying the original solution inside the housing 1, a second motor 5 below the housing 1, a feeding component 2 for uniform feeding below the top plate 103, a first motor 4 above the top plate 103, a limiting groove 104 below the top plate 103, the feeding component 2 being located inside the membrane separation component 3, and a support rod 6 being provided between the feeding component 2 and the membrane separation component 3.

[0023] Example 1: Please refer to Figure 1-4 In this embodiment of the present invention, a membrane separation device includes a membrane separation component 3 comprising a filter membrane body 301. A first partition 302 and a second partition 304 are respectively disposed at the upper and lower ends of the filter membrane body 301. A positioning plate 303 is disposed on the upper part of the first partition 302, and a slag collection bin 305 is disposed below the second partition 304. A plurality of through holes 306 are disposed on the surface of the slag collection bin 305. A second motor 5 is connected to the lower shaft of the slag collection bin 305. The housing 1 is a hollow cylindrical structure with an open upper part. The upper end of the positioning plate 303 is located inside a limiting groove 104. A plurality of balls are disposed inside the limiting groove 104, and the positioning plate 303 contacts the balls. A first sealing ring 105 and a second sealing ring 106 are respectively disposed at the contact points between the first partition 302 and the second partition 304 and the inner wall of the housing 1.

[0024] The first partition 302 and the second partition 304 divide the space between the housing 1 and the filter membrane body 301 into an upper storage space and a lower storage space. The first sealing ring 105 and the second sealing ring 106 are used to prevent the liquid inside the upper storage space and the lower storage space from leaking out.

[0025] The upper end of the support rod 6 is provided with a protrusion 602, and the lower end of the support rod 6 extends into the interior of the slag collection bin 305. The protrusion 602 is screwed to the top plate 103. The side of the support rod 6 is provided with a brush plate 601, which is attached to the surface of the filter membrane body 301. The lower end of the brush plate 601 is attached to the inner wall of the slag collection bin 305. When the membrane separation assembly 3 rotates, the brush plate 601 automatically scrapes off the filter residue attached to the surface of the filter membrane body 301 and the inner wall of the slag collection bin 305.

[0026] The feeding assembly 2 includes a feeding pipe 201, a driven gear 202, a feeding bin 203, and a discharge port 204. The lower end of the feeding pipe 201 extends through the top plate 103 into the interior of the feeding bin 203. The feeding pipe 201 is connected to the top plate 103 by a bearing. The lower end of the feeding pipe 201 is fixedly connected to the feeding bin 203. The driven gear 202 is connected to the top of the feeding bin 203. The discharge port 204 is located on the surface of the feeding bin 203. The first motor 4 is mounted on the top plate 103. The drive gear 401 is shaft-connected to the first motor 4. The drive gear 401 and the driven gear 202 mesh.

[0027] When the sheep milk concentrate enters the feed hopper 203 through the feed pipe 201, the first motor 4 drives the feed hopper 203 to rotate by rotating the drive gear 401. This causes the sheep milk concentrate to be sprayed onto the filter membrane body 301 from the discharge port 204 by centrifugal force. Then, the second motor 5 drives the filter membrane body 301 to rotate. The rotation speed of the filter membrane body 301 is higher than that of the feed hopper 203, causing the sheep milk concentrate on the surface of the filter membrane body 301 to be separated into purified liquid and filter residue by centrifugal force. The purified liquid passes through... The filter membrane body 301 enters the upper storage space and is discharged from the liquid outlet 101. The filter residue adheres to the filter membrane body 301 and is swept off into the slag collection bin 305 by the brush plate 601. Then, it enters the lower storage space through the through hole 306 by centrifugal force and is discharged from the slag outlet 102. Compared with the method of backwashing after the filter membrane body 301 is blocked, it is only necessary to clean the stubborn filter residue accumulation layer on the filter membrane body 301 periodically, which can meet the needs of continuous separation of sheep milk and improve production efficiency.

[0028] Since some of the purified liquid will fall along the filter membrane body 301 into the slag collection bin 305, a small amount of purified liquid and filter residue will mix in the slag collection bin 305 and enter the lower storage space, and be discharged from the slag outlet 102 along with the filter residue. Therefore, the discharged filter residue needs to be filtered again to improve the collection rate of purified liquid.

[0029] Example 2: Please refer to Figure 1-4 The difference from Example 1 is that the filter membrane body 301 has a funnel-shaped structure with an upper opening larger than the lower opening. One end of the brush plate 601 is adapted to fit the surface of the filter membrane body 301, thereby improving the separation effect of the filter membrane body 301 on the sheep milk raw liquid, reducing the total amount of purified liquid entering the slag collection chamber 305 along the filter membrane body 301, and thus reducing the content of purified liquid in the subsequently discharged filter residue.

[0030] The working principle of this utility model is as follows: After the sheep milk raw liquid is inside the rotating feed hopper 203, it is sprayed onto the filter membrane body 301 by centrifugal force. At the same time, the filter membrane body 301 rotates, and the sheep milk raw liquid is separated into purified liquid and filter residue by centrifugal force. The purified liquid enters the upper storage space and is discharged from the liquid outlet 101. The filter residue is peeled off from the filter membrane body 301 by the brush plate 601 and enters the lower storage space and is discharged from the residue outlet 102. This meets the requirements of continuous separation of sheep milk and improves production efficiency.
