Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a slag-removing trolley for discharging and taking soy sauce crude oil. Background Technique

[0002] Soy sauce is a traditional Chinese liquid condiment. In the soy sauce production process, high-salt dilute-state fermentation has gradually become the mainstream. Its production process uses soybeans or defatted soybeans, wheat or wheat flour as raw materials. After steaming and Aspergillus oryzae koji making, it is mixed with brine to form a thin mash, which is put into a fermentation tank. After a period of fermentation, the fermented mash gradually floats to form an upper layer of fermented mash and a lower layer of crude oil. During the fermentation process, the staff opens the oil discharge port at the bottom of the tank every once in a while to discharge a part of the soy sauce crude oil, and then pumps it to the surface of the fermented mash through a centrifugal pump. This process is called oil pouring, and generally about 7 times of pouring are required during the whole fermentation process. After fermentation is completed, the soy sauce crude oil is discharged and taken from the oil discharge port at the bottom of the fermentation tank, and the discharged and taken soy sauce crude oil needs to go through multiple treatment processes such as heating and filtration. The heating of soy sauce crude oil generally uses a plate heat exchanger, and its working principle is that thin rectangular channels are formed between various plate sheets, and heat exchange is carried out through the plate sheets; when filtering soy sauce crude oil, a diaphragm filter press is often used for filtration. The filtration principle of this equipment is that a filter cloth is placed between the diaphragm plate and the filter plate, and a fine filter aid filter cake layer is formed through precoating, and then small impurities in the soy sauce crude oil are filtered out. Then, the diaphragm plate is pressurized through a hydraulic system, so that the diaphragm plate generates a certain deformation, thereby realizing the extrusion of the filter plate and squeezing out the residual liquid in the filter cake.

[0003] During the process of discharging and taking soy sauce crude oil, some raw material sauce residues such as wheat bran and soybeans that are not decomposed and suspended in the soy sauce crude oil will flow out along with the soy sauce crude oil. Among them, in winter, due to the low temperature, the fermentation is slow, and the fermented mash floats poorly, and there will be more large-particle sauce residues such as bean dregs in the discharged and taken soy sauce crude oil. In this case, when heating soy sauce crude oil with a plate heat exchanger, due to the small flow channels of the heat exchanger plate sheets, large-particle bean dregs in the crude oil will block the flow channels, resulting in fouling inside the plate sheets, reducing the heating efficiency, affecting the heat exchange effect and the service life of the heat exchanger, etc.; in addition, large flakes of bran and bean dregs in the soy sauce crude oil will cover the surface of the filter cake during filtration, resulting in the blockage of the filtration channels of the filter cake, greatly reducing the filtration speed, resulting in filtration interruption, affecting the filtration efficiency, and thus causing a series of problems such as rapid clogging of the diaphragm filter press, frequent pressing, and easy rupture of the diaphragm plate. Content of the Utility Model

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A slag removal trolley for taking and placing crude soy sauce includes a slag removal device, an oil collecting tank and a slag collecting tank;

[0007] The slag collecting tank is horizontally arranged on one side of the oil collecting tank;

[0008] A slag removal sieve plate is arranged inside the slag removal device, and the slag removal sieve plate is arranged directly above the oil collecting tank;

[0009] The slag removal sieve plate is provided with dense small holes, the small holes communicate with the oil collecting tank, the slag removal sieve plate is inclined, and its lower end is correspondingly arranged with the slag collecting tank;

[0010] Deflector plates are arranged on both sides of the slag removal sieve plate, and the deflector plates extend from above the oil collecting tank to above the slag collecting tank.

[0011] Furthermore, the slag removal sieve plate is a punched plate with a pore size of 10-20 meshes, and the slag removal sieve plate is inclined 8-12° compared with the horizontal direction.

[0012] Furthermore, a liquid receiving tank is arranged below the slag removal sieve plate, the liquid receiving tank is arranged inside the oil collecting tank, the liquid receiving tank is inclined, and its lower end is correspondingly arranged with the side wall of the oil collecting tank.

[0013] Furthermore, the liquid receiving tank is parallel to the slag removal sieve plate.

[0014] Furthermore, the depth of the liquid receiving tank is 5-8 cm, and the height of the deflector plate is 10-15 cm.

[0015] Furthermore, at least one oil inlet is arranged at the top of the slag removal device.

[0016] Furthermore, the bottoms of the oil collecting tank and the slag collecting tank are both inclined. An oil inlet pipe is arranged at the bottom of the oil collecting tank, and the oil inlet pipe is connected with an oil extraction pump; a slag inlet pipe is arranged at the bottom of the slag collecting tank, and the slag inlet pipe is connected with a slag extraction pump.

[0017] Furthermore, an oil collecting tank liquid level gauge and a slag collecting tank liquid level gauge are respectively arranged in the oil collecting tank and the slag collecting tank.

[0020] Generally speaking, the present utility model has the following advantages:

[0021] During use, the crude soy sauce oil enters from the upper end of the slag removal sieve plate. Since the slag removal sieve plate is inclined and its lower end is correspondingly arranged with the slag collection tank, the crude soy sauce oil flows under the action of the height difference before and after the slag removal sieve plate. The slag removal sieve plate can automatically intercept impurities such as soybean dregs in the crude soy sauce oil. The soybean dregs and other impurities intercepted on the slag removal sieve plate will be impacted by the next batch of soy sauce dregs added from the upper end of the slag removal sieve plate and will be washed along the inclined slag removal sieve plate into the slag collection tank; guide plates are provided on both sides of the slag removal sieve plate, and the guide plates extend from above the oil collection tank to above the slag collection tank, which can ensure that the soy sauce dregs are washed into the slag collection tank for collection. Since the slag removal sieve plate is provided with dense small holes, the crude soy sauce oil filtered by the slag removal sieve plate flows downward from the dense small holes of the slag removal sieve plate into the oil collection tank, so that the crude soy sauce oil can be automatically deslagged during the oil discharge process, realizing the automatic separation of oil and slag. The deslagged crude soy sauce oil has no impurities, is clear in state, and can be directly pumped into the plate heat exchanger for heating, avoiding the blockage of the flow channel by soybean dregs and resulting in scale formation inside the plate, ensuring the heat exchange effect and the service life of the heat exchanger. At the same time, during the filtration stage, the situation where the filter cake is blocked by soybean dregs during the filtration of the diaphragm filter press can be effectively reduced, ensuring the continuity of filtration, reducing frequent pressing, reducing the number of breakages of the diaphragm plates, improving the processing efficiency of the crude soy sauce oil, and extending the service life of the equipment.

[0031] The following will further elaborate on the present utility model in detail

[0032] As Figures 1-3 shown, a slag-removing trolley for discharging and collecting crude soy sauce includes a slag-removing device 1, an oil collecting tank 2, and a slag collecting tank 3 installed on the trolley. The slag-removing device 1 is arranged directly above the oil collecting tank 2. The bottom surfaces of the oil collecting tank 2 and the slag collecting tank 3 are designed as inclined planes, and the two are arranged side by side closely, combined into a conical bottom shape

[0033] Among them, the slag-removing device 1 is used to intercept and remove large pieces of bran and bean dregs during the discharging and collecting process of crude soy sauce. Frame 6 is provided at the bottom of the outer side walls of both the oil collecting tank 2 and the slag collecting tank 3. Wheel 7 is arranged below the frame 6. A fuel pump 4 and a slag pump 5 are respectively installed on the frame 6. The bottom of the oil collecting tank 2 is connected to an oil inlet pipe 41. One end of the oil inlet pipe 41 away from the oil collecting tank 2 is connected to the fuel pump 4. An oil outlet pipe 42 is connected to the fuel pump 4. The bottom of the slag collecting tank 3 is connected to a slag inlet pipe 51. One end of the slag inlet pipe 51 away from the slag collecting tank 3 is connected to the slag pump 5. A slag outlet pipe 52 is connected to the slag pump 5

[0034] By combining and installing the slag-removing device 1, the oil collecting tank 2, the slag collecting tank 3, the fuel pump 4, and the slag pump 5 and fixing them on the wheel 7, it is convenient to move the trolley to adapt to oil discharging in different sites. And because the bottom surfaces of both the oil collecting tank 2 and the slag collecting tank 3 are designed as inclined planes, and the oil inlet pipe 41 and the slag inlet pipe 51 are both arranged to communicate with the bottom of their respective corresponding collecting tanks, the materials in the tanks can be emptied to the greatest extent possible

[0035] In one embodiment, the slag-removing device 1 includes a slag-removing sieve plate 11, a liquid receiving tank 12, a diversion plate 13, and an oil inlet 14

[0036] Among them, the slag-removing sieve plate 11 is a punched plate with a pore size of 10 - 20 meshes. The slag-removing sieve plate 11 is inclined 8 - 12° compared with the horizontal direction. The liquid receiving tank 12 is arranged parallel to the lower part of the slag-removing sieve plate 11, and the depth of the liquid receiving tank 12 is 5 - 8 cm. Diversion plates 13 with a height of 10 - 15 cm are arranged on both sides of the slag-removing sieve plate 11. One or more oil inlets 14 are arranged at the top end of the inclined slag-removing sieve plate 11

[0037] The width of the slag-removing device 1 is smaller than the widths of the oil collecting tank 2 and the slag collecting tank 3, so that the separated crude soy sauce and bean dregs can completely enter the oil collecting tank 2 and the slag collecting tank 3. One end of the oil inlet 14 of the slag-removing device 1 is fixed to the side of the oil collecting tank 2 away from the slag collecting tank 3, and the other end of the slag-removing device 1 is fixed to the side of the oil collecting tank 2 adjacent to the slag collecting tank 3

[0038] The oil outlet at the bottom of the external fermentation tank is connected to the oil inlet 14 at the top of the slag removal sieve plate 11 through a detachable oil delivery hose, so that the crude soy sauce enters from the upper part of the slag removal sieve plate 11. Since there are dense small holes on the slag removal sieve plate 11, the crude soy sauce naturally flows under the action of the height difference before and after the slag removal sieve plate 11. The slag removal sieve plate 11 can automatically intercept impurities such as soybean dregs larger than 0.1 cm. These impurities will be washed into the slag collection tank 3 by the next batch of soy sauce residue. After the crude soy sauce is deslagged by the slag removal sieve plate 11, the crude soy sauce falls through the small holes under the action of gravity into the liquid receiving tank 12, and then flows down along the liquid receiving tank 12. After contacting the side wall of the oil collection tank 2, it flows down along the side wall of the oil collection tank 2 into the oil collection tank 2. The frictional force between the crude soy sauce and the side wall of the oil collection tank 2 is used to slow down the falling speed of the crude soy sauce, avoiding the bad situation of excessive foaming in the oil collection tank 2 due to the excessive impact force generated by the vertical fall of the crude soy sauce from a high altitude. The deslagging device 1 achieves the deslagging effect through ingenious designs such as the slag removal sieve plate 11, and separately collects and temporarily stores the separated crude soy sauce and soybean dregs.

[0039] In one embodiment, an oil collection tank level gauge 21 for controlling the oil extraction pump 4 is provided in the oil collection tank 2. The oil collection tank level gauge 21 includes an oil collection tank level gauge upper limit 211 and an oil collection tank level gauge lower limit 212.

[0040] A slag collection tank level gauge 31 for controlling the slag extraction pump 5 is provided in the slag collection tank 3. The slag collection tank level gauge 31 includes a slag collection tank level gauge upper limit 311 and a slag collection tank level gauge lower limit 312.

[0041] During operation, the level gauge continuously detects the liquid level in the collection tank and sends a signal to start or stop the corresponding transfer pump, avoiding the need for personnel to observe the liquid level and control the start and stop of the transfer pump, and achieving the effect of liquid level monitoring and automatic start and stop through the level gauge.

[0042] In one embodiment, an oil collection tank drain pipe 22 is provided at the bottom of the oil collection tank 2, and an oil collection tank drain valve 221 is installed on the oil collection tank drain pipe 22; a slag collection tank drain pipe 32 is provided at the bottom of the slag collection tank 3, and a slag collection tank drain valve 321 is installed on the slag collection tank drain pipe 32.

[0043] A drain pipe is provided at the bottom of the collection tank for discharging sewage during cleaning. The cleaning sewage can be completely drained without residue, avoiding the health hazards caused by sewage residue.

[0044] The working process of the present utility model is as follows:

[0045] Connect the oil outlet at the bottom of one or more fermentation tanks to the oil inlet 14 through a detachable oil delivery hose. The crude soy sauce at the bottom of the tank flows out from the bottom of the fermentation tank by its own weight. When passing through the slag removal sieve plate 11, under the action of the height difference before and after it, soybean dregs, bran, etc. are intercepted and flow into the slag collection tank 3, and the soy sauce falls into the liquid receiving tank 12 under the action of gravity and then flows into the oil collection tank 2; when the liquid level in the oil collection tank 2 reaches the upper limit 211 of the oil collection tank level gauge, the oil pumping pump 4 starts to work and pump oil. The crude soy sauce enters the oil pumping pump 4 through the connected oil inlet pipe 41 and is then pumped out through the oil outlet pipe 42. When the liquid level in the oil collection tank 2 drops to the lower limit 212 of the oil collection tank level gauge, the oil pumping pump 4 stops working. Wait for the liquid level in the oil collection tank 2 to reach the upper limit 211 of the oil collection tank level gauge, and the oil pumping pump 4 restarts to pump oil, and so on in a cycle; when the liquid level in the slag collection tank 3 reaches the upper limit 311 of the slag collection tank level gauge, the slag pumping pump 5 starts to work and pump slag. The soybean dregs enter the slag pumping pump 5 through the connected slag inlet pipe 51 and are then pumped out through the slag outlet pipe 52. When the liquid level in the slag collection tank 3 drops to the lower limit 312 of the slag collection tank level gauge, the slag pumping pump 5 stops working. Wait for the liquid level in the slag collection tank 3 to reach the upper limit 311 of the slag collection tank level gauge, and the slag pumping pump 5 restarts to pump slag, and so on in a cycle. The above is the working state in the automatic mode. The whole device has a compact structure, novel structure, ingenious design, strong applicability and is convenient for popularization.

[0046] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
