Description

Technical Field

[0001] This utility model relates to the technical field of protein separation equipment, specifically to a microbial protein solid-liquid separation device. Background Technology

[0002] Microorganisms include a large group of organisms such as bacteria, viruses, fungi, and some small protozoa and microalgae. They are tiny in size, closely related to humans, and encompass a wide range of species, both beneficial and harmful. They are widely involved in many fields such as food, medicine, industry, agriculture, environmental protection, and sports. Microbial protein, also known as single-cell protein, is extremely rich in nutrients. Among them, the protein content is as high as 40% to 80%, which is 10% to 20% higher than soybeans and more than 20% higher than meat, fish, and cheese. The amino acid composition is relatively complete, containing all eight essential amino acids for the human body, especially lysine, which is less abundant in grains. Therefore, during the production process, microbial protein undergoes solid-liquid separation.

[0003] In related technologies, bag-type solid-liquid separators mostly use a detachable sieve cylinder installed inside the re-separation cylinder. Microorganisms containing protein raw materials are poured into the re-sieve cylinder, and a separation motor is installed at the bottom of the re-separation cylinder. The separation motor is then rotatably connected to the sieve cylinder, thereby driving the sieve cylinder to rotate, thus achieving the effect of solid-liquid separation.

[0004] However, in existing solid-liquid separation devices, after centrifugation, the screen wall of the sieve cylinder, being in the form of a filter screen, throws the separated material onto the inner wall of the separation cylinder during rotation. This causes the separated material to adhere to the inner wall of the separation cylinder, making it difficult to clean and affecting the quality of subsequent separations. To solve the above problems, a microbial protein solid-liquid separation device is proposed. Utility Model Content

[0005] In view of this, the present invention provides a microbial protein solid-liquid separation device. The present invention starts a rotary motor to drive the rotating shaft to rotate the connecting ring, which in turn causes the linkage rod connected to the connecting ring to rotate, thereby causing the scraper in the scraping assembly to rotate. The scraper blades rotate and scrape off the deposits on the inner wall of the separation cylinder, thereby facilitating the cleaning of the inner wall of the separation cylinder and preventing the deposits on the inner wall of the separation cylinder from affecting the subsequent separation quality.

[0006] To solve the above-mentioned technical problems, this utility model provides a microbial protein solid-liquid separation device, including a separation cylinder mounted on a frame, a separation motor mounted at the bottom of the separation cylinder, a sieve cylinder rotatably connected to the separation motor inside the separation cylinder, a detachable cylinder cover mounted on the top of the separation cylinder, a cavity inside the cylinder cover, a rotary motor mounted inside the cylinder cover, a rotary shaft mounted through the bottom of the cylinder cover at the output end of the rotary motor, a connecting ring mounted on the surface of the rotary shaft, a linkage rod fixedly mounted on one side of the connecting ring, and a scraping assembly mounted at the bottom of the linkage rod.

[0007] The scraping assembly includes a connecting column fixedly connected to the linkage rod. The connecting column is used to connect the connecting rod to the linkage rod. A connecting rod is provided at the bottom of the connecting column. The connecting rod is used to connect the connecting column to the scraper. The connecting rod is L-shaped. The side of the connecting rod near the rotating shaft is arc-shaped, and the side of the connecting rod away from the rotating shaft is rectangular. A scraper is provided on the side of the connecting rod away from the rotating shaft. The scraper is used to scrape off the deposits on the inner wall of the separation cylinder.

[0008] One side of the scraper blade faces the inner wall of the separation cylinder, and the distance between the scraper blade and the inner wall of the separation cylinder is 1~2 mm.

[0009] A sealing groove is provided inside the top wall of the separator cylinder to receive the sealing ring. A sealing ring is provided on the inner ring of the bottom of the cylinder cover. The sealing ring is inserted into the sealing groove to seal the separator cylinder and the cylinder cover. The sealing groove and the sealing ring are matched for sealing.

[0010] The bottom of the rotating motor is equipped with a buffer plate, and a rubber shock-absorbing column is installed at each of the four corners of the bottom of the buffer plate.

[0011] A handle is fixedly installed in the center of the top of the cylinder cap. The handle is a hollow rectangle.

[0012] Several heat dissipation holes are provided around the upper part of the cylinder cover, and each heat dissipation hole penetrates the cover wall.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. By starting the rotary motor, the rotating shaft drives the connecting ring to rotate, which in turn causes the linkage rod connected to the connecting ring to rotate, thereby causing the scraper in the scraping assembly to rotate. The scraper blades then rotate and scrape off the deposits on the inner wall of the separation cylinder, making it easier to clean the inner wall of the separation cylinder and preventing the deposits on the inner wall of the separation cylinder from affecting the subsequent separation quality.

[0015] 2. The distance between the scraper blade and the inner wall of the separator cylinder should be 1-2 mm to prevent the scraper blade from directly contacting the inner wall of the separator cylinder, thereby wearing down the scraper and reducing its service life.

[0016] 3. The handle makes it easy for personnel to remove the cylinder cover, thus facilitating the opening and closing of the cylinder and the cover. The heat dissipation holes are used to dissipate heat from the rotary motor, thereby improving the working efficiency of the rotary motor. Attached Figure Description

Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] like Figure 1-5As shown: This embodiment provides a microbial protein solid-liquid separation device, including a separation cylinder 100 mounted on a frame. The separation cylinder 100 is made of stainless steel. A separation motor 101 is mounted at the bottom of the separation cylinder 100. A support frame is mounted at the bottom of the separation motor 101 and connected to the bottom of the frame. A sieve cylinder 102 is rotatably connected to the separation motor 101 inside the separation cylinder 100. The sieve cylinder 102 adopts a double-layer sieve cylinder 102 with a hollow top. A cylinder cover 200 is detachably mounted on the top of the separation cylinder 100. A sealing block can be added to the bottom of the cylinder cover 200. The size of the sealing block is smaller than the inner ring size of the sealing ring 204. A cavity 201 is provided inside the cylinder cover 200. The cylinder cover 200 can adopt a split and detachable design for easy subsequent maintenance of the rotating motor 202. The rotating motor 202 is installed inside the cylinder cover 200 and is used to drive the rotating shaft 300 to rotate. A rotating shaft 300 is provided at the bottom of the cylinder cover 200 through the output end. The rotating shaft 300 is mechanically sealed to the rotating motor 202 via a coupling. The rotating shaft 300 is used to connect the output end of the rotating motor 202 to the connecting ring 301, thereby causing the connecting ring 301 to rotate. The surface of the rotating shaft 300 is provided with the connecting ring 301, which can be welded to the rotating shaft 300. The connecting ring 301 is used to connect the rotating shaft 300 to the linkage rod 302. The linkage rod 302 is fixedly provided on one side of the connecting ring 301, and the linkage rod 302 can be welded to the connecting ring 301. The linkage rod 302 is used to connect the connecting ring 301 to the scraping assembly 400, thereby causing the rotating motor 202 to drive the scraping assembly 400 to rotate, thereby scraping and removing the deposits on the inner wall of the separation cylinder 100. The scraping assembly 400 is provided at the bottom of the linkage rod 302.

[0025] In use, the rotating shaft 300 is driven to rotate by starting the rotating motor 202, which in turn causes the linkage rod 302 connected to the connecting ring 301 to rotate, thereby causing the scraper 403 in the scraping assembly 400 to rotate. The scraper 403 uses its cutting edge to scrape off the deposits on the inner wall of the separation cylinder 100, thus facilitating the cleaning of the inner wall of the separation cylinder 100 and preventing the deposits on the inner wall of the separation cylinder 100 from affecting the subsequent separation quality.

[0026] This embodiment provides a microbial protein solid-liquid separation device.

[0027] like Figure 3 , 4As shown in Figure 5: The scraper assembly 400 includes a connecting post 401 fixedly connected to the linkage rod 302. The connecting post 401 and the linkage rod 302 can be welded together or fixed by bolts. The connecting post 401 is used to connect the connecting rod 402 and the linkage rod 302. A connecting rod 402 is provided at the bottom of the connecting post 401. The connecting rod 402 and the connecting post 401 are fixed by bolts or welded together. The connecting rod 402 is used to connect the connecting post 401 to the scraper 403. The connecting rod 402 is L-shaped. The connecting rod 402 is arc-shaped on the side near the rotating shaft 300, and rectangular on the side away from the rotating shaft 300. A scraper 403 is provided on the side of the connecting rod 402 away from the rotating shaft 300. The handle of the scraper 403 is U-shaped and can be fixed to the connecting rod 402 by bolts. The scraper 403 is used to scrape off the adhering substances on the inner wall of the separation cylinder 100. One side of the blade of the scraper 403 faces the inner wall of the separation cylinder 100, and the distance between the blade of the scraper 403 and the inner wall of the separation cylinder 100 is 1~2 mm.

[0028] Its function is as follows: the connecting column 401 is used to connect the connecting rod 402 and the linkage rod 302; the connecting rod 402 is used to connect the connecting column 401 and the scraper 403; the scraper 403 is used to scrape off the deposits on the inner wall of the separation cylinder 100; the distance between the cutting edge of the scraper 403 and the inner wall of the separation cylinder 100 is 1~2 mm to prevent the cutting edge of the scraper 403 from directly contacting the inner wall of the separation cylinder 100, thereby wearing down the scraper 403 and reducing its service life.

[0029] like Figure 1 , 2 As shown in Figures 3 and 4: A sealing groove 203 is provided inside the top wall of the separation cylinder 100. The sealing groove 203 is embedded in the top wall of the separation cylinder 100. The sealing groove 203 is used to receive the sealing ring 204. The sealing ring 204 is circular and made of stainless steel. The sealing ring 204 is welded to the cylinder cover 200. A sealing ring 204 is provided on the inner ring of the bottom of the cylinder cover 200. The sealing ring 204 is used to insert into the sealing groove 203 to seal the separation cylinder 100 and the cylinder cover 200. The sealing groove 203 and the sealing ring 204 are sealed and adapted.

[0030] Its effect is as follows: the sealing ring 204 is inserted into the sealing groove 203 to seal the separation cylinder 100 and the cylinder cover 200, thereby strengthening the connection between the separation cylinder 100 and the cylinder cover 200.

[0031] like Figure 2 , 3As shown in Figure 5: A buffer plate 205 is provided at the bottom of the housing of the rotary motor 202. The buffer plate 205 is used to connect the rubber shock-absorbing column 206 to the inner wall of the cylinder cover 200, thereby supporting the rotary motor 202. The buffer plate 205 and the housing of the rotary motor 202 can be connected by bolts. The buffer plate 205 can be made of polyurethane.

The rubber shock-absorbing column 206 and the buffer plate 205 can be fixed by bolts.

[0032] Its effect is as follows: the buffer plate 205 is used to connect the rubber shock absorber 206 to the inner wall of the cylinder cover 200, thereby supporting the rotary motor 202. The rubber shock absorber 206 is used to reduce the vibration generated by the rotary motor 202 during operation, thereby reducing the spread of equipment noise.

[0033] like Figure 1 , 2 As shown in Figure 3: A handle 103 is fixedly installed in the center of the top of the cylinder cover 200. The handle 103 is fixed to the top of the cylinder cover 200 by bolts. The handle 103 is a hollow rectangle. Several heat dissipation holes 104 are provided around the upper part of the cylinder cover 200. A dustproof net can be attached to the outside of the cylinder cover 200 to prevent dust from entering the inside of the cylinder cover 200 through the heat dissipation holes 104. Each heat dissipation hole 104 penetrates the cover wall of the cylinder cover 200.

[0034] Its effects are as follows: the handle 103 makes it easy for personnel to remove the cylinder cover 200, thereby facilitating the opening and closing of the cylinder 100 and the cylinder cover 200; the heat dissipation hole 104 is used to dissipate heat from the rotary motor 202, thereby improving the working efficiency of the rotary motor 202.

[0035] Working principle: After solid-liquid separation in the separation cylinder 100, deposits will appear on the inner wall of the separation cylinder 100. By starting the rotary motor 202, the rotary shaft 300 drives the connecting ring 301 to rotate, which in turn causes the linkage rod 302 connected to the connecting ring 301 to rotate. This causes the scraping assembly 400 connected to the linkage rod 302 to rotate, which in turn causes the scraper 403 inside the scraping assembly 400 to rotate. The scraper 403 uses its cutting edge to scrape away the deposits on the inner wall of the separation cylinder 100, thus facilitating the cleaning of the inner wall of the separation cylinder 100 and preventing the deposits on the inner wall of the separation cylinder 100 from affecting the subsequent separation quality.

[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
