[0015] 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.

[0016] Example 1 Please see Figure 1-4 The present invention provides the following technical solution: a microbial fermentation tank for microbial oil recovery, comprising a tank assembly 1, a cleaning component 6 installed at the center of the tank assembly 1, a discharge pipe 5 fixedly installed on one side of the bottom of the tank assembly 1, support blocks 4 fixedly installed below the tank assembly 1 and on both sides of the cleaning component 6, multiple legs 2 provided below the two support blocks 4, the two support blocks 4 and the multiple legs 2 are connected by a storage and conveying device 3, and an auxiliary disinfection device 7 fixedly installed on one side of the top of the tank assembly 1.

[0017] Specifically, the storage and conveying device 3 includes a support box 31, a conveying component 32, a movable box 33, and an electric telescopic rod 34. The two support blocks 4 and the multiple legs 2 are connected through the support box 31. The movable box 33 is provided inside the support box 31. The support box 31 and the movable box 33 are connected through the electric telescopic rod 34. The conveying component 32 is provided on the side of the movable box 33 away from the electric telescopic rod 34.

[0018] By adopting the above technical solution, staff can temporarily store fermented microorganisms when needed through the combination of structures such as the mobile box 33 and the electric telescopic rod 34, thereby better meeting the work needs in different situations.

[0019] Specifically, the height of the inner top surface of the support box 31 is equal to the height of the outer top surface of the movable box 33.

[0020] By adopting the above technical solution, the fermenter can ensure that the inner top surface of the support box 31 and the outer top surface of the moving box 33 are in close contact with each other, thereby preventing the leakage of the bacterial liquid containing microorganisms in the moving box 33.

[0021] Specifically, the delivery assembly 32 includes a hose 321, a pump body 322, a first valve 323, and a connecting pipe 324. The pump body 322 is located on the side of the movable box 33 away from the electric telescopic rod 34. The connecting pipe 324 is fixedly connected between the liquid inlet end of the pump body 322 and the movable box 33. The first valve 323 is fixedly installed near the center of the connecting pipe 324. The hose 321 is fixedly connected to the side of the pump body 322 away from the connecting pipe 324.

[0022] By adopting the above technical solution, staff can transport fermented microorganisms through the cooperation of structures such as hose 321 and pump body 322 when needed, thereby better meeting the work needs in different situations.

[0023] In this embodiment, when a fermentation tank is needed for microbial oil recovery, the operator feeds the raw materials into the tank assembly 1 for fermentation. After fermentation, the electric telescopic rod 34 in the storage and conveying device 3 is activated, thereby moving the moving box 33 to below the discharge pipe 5. Then, the discharge pipe 5 is opened, and the bacterial solution containing microorganisms is discharged from the discharge pipe 5 and falls into the moving box 33. If temporary storage is required, the electric telescopic rod 34 is activated to move the moving box 33 and microorganisms into the support box 31. If conveying is required, the end of the hose 321 in the conveying assembly 32 is placed in the required position, the first valve 323 is opened, and the pump 322 is activated. Under the action of the pump 322, the bacterial solution containing microorganisms passes through the connecting pipe 324 into the pump 322, and then passes through the hose 321 to be discharged, thereby conveying. Then, the operator operates the cleaning assembly 6 to clean. After use, the support legs 2 and the support block 4 provide support.

[0024] Example 2 The difference between this embodiment and embodiment 1 is that the auxiliary disinfection device 7 includes a connecting box 71, a second valve 72, an air supply pipe 73, an electric heating rod 74, a fan 75, and a filter screen 76. An air supply pipe 73 is fixedly installed on one side of the top of the tank assembly 1. A second valve 72 is fixedly installed near the center of the air supply pipe 73. A connecting box 71 is fixedly installed on the side of the air supply pipe 73 away from the tank assembly 1. Multiple electric heating rods 74 are fixedly installed inside the connecting box 71. A fan 75 is fixedly installed on the side of the connecting box 71 away from the air supply pipe 73.

[0025] By adopting the above technical solution, staff can use the electric heating rod 74 and the fan 75 to dry and heat the inside of the tank assembly 1 when needed, thereby eliminating microorganisms inside the tank assembly 1 and preventing the presence of microbial residues inside the tank assembly 1.

[0026] Specifically, the auxiliary disinfection device 7 also includes a filter screen 76, which is fixedly connected to the side of the fan 75 away from the connecting box 71.

[0027] By adopting the above technical solution, the fermenter can prevent external impurities from entering the blower 75 through the filter screen 76, thereby preventing external impurities from entering the tank assembly 1 and reducing the possibility of adverse effects on the operation.

[0028] In this embodiment, before operation, the operator can open the discharge pipe 5 and the second valve 72 in the auxiliary disinfection device 7, and then start the blower 75 and each electric heating rod 74. The blower 75 sends the air filtered by the filter screen 76 into the connection box 71, and then the air is heated by each electric heating rod 74. The hot air passes through the air supply pipe 73 and enters the tank assembly 1, thereby drying and heating the inside of the tank assembly 1, and then disinfecting the microorganisms inside the tank assembly 1, preventing the presence of microbial residues inside the tank assembly 1. The used air is discharged from the discharge pipe 5.

[0029] The structure and principle of the tank assembly 1 (comprising a tank body, observation port, and top cover), the discharge pipe 5, and the cleaning assembly 6 (comprising a cleaning brush, fixing plate, fixing rod, gear disc, sliding sleeve, sliding rod, rotating shaft, lead screw, internal threaded disc, first mounting plate, sealed bearing, first motor, nozzle, second mounting plate, third mounting plate, hydraulic cylinder, gear, second motor, L-shaped plate, support plate, and connecting rod) in this utility model are disclosed in Chinese patent application No. 202120946767.9, which discloses a microbial fermentation tank for microbial enhanced oil recovery technology. Its working principle is that during use, the piston rod of the hydraulic cylinder pushes the cleaning brush against the inner wall of the tank body. The output shaft of the second motor drives the gear to rotate, thereby rotating the gear disc. The rotation of the gear disc causes the support plate to rotate, thus rotating the liquid... The cleaning brush installed at the end of the piston rod of the pressure cylinder rotates to clean the inner wall of the tank, removing the bacterial liquid adhering to the inner wall. The output shaft of the first motor drives the rotating shaft to rotate, causing the lead screw to rotate accordingly. This causes the internal threaded disc to move up and down on the lead screw, thereby adjusting the cleaning height of the cleaning brush. This allows for a thorough cleaning of the inner wall of the tank to ensure cleanliness for the next use in microbial fermentation. The sliding rod, which is slidably sleeved in the sliding sleeve, provides guidance for the internal threaded disc to move up and down to adjust its height. The spray nozzle sprays water onto the inner wall of the tank, working in conjunction with the cleaning brush to make the cleaning brush clean the inner wall of the tank more thoroughly, thereby improving the cleaning effect. The cleaning brush is installed on the side of the first mounting plate for easy replacement, and the observation port allows for easy observation of the microbial fermentation inside the tank.

[0030] The working principle and usage process of this utility model are as follows: When a fermentation tank is required for microbial oil recovery, the operator feeds the raw materials into the tank assembly 1 for fermentation. After fermentation, the electric telescopic rod 34 in the storage and conveying device 3 is activated, thereby moving the moving box 33 to below the discharge pipe 5. Then, the discharge pipe 5 is opened, and the bacterial solution containing microorganisms is discharged from the discharge pipe 5 and falls into the moving box 33. If temporary storage is required, the electric telescopic rod 34 is activated to move the moving box 33 and microorganisms into the support box 31. If conveying is required, the end of the hose 321 in the conveying assembly 32 is placed in the required position, the first valve 323 is opened, and the pump 322 is activated. Under the action of the pump 322, the bacterial solution containing microorganisms passes through the connecting pipe. Air 324 enters the pump body 322 and then exits through the hose 321 for conveying. Then, the operator can operate the cleaning component 6 for cleaning. After use, the support legs 2 and the support block 4 provide support. Before operation, the operator can open the discharge pipe 5 and the second valve 72 in the auxiliary disinfection device 7, and then start the blower 75 and each electric heating rod 74. The blower 75 sends the air filtered by the filter screen 76 into the connection box 71, and then the air is heated by each electric heating rod 74. The hot air enters the tank assembly 1 through the air supply pipe 73, thereby drying and heating the inside of the tank assembly 1, and then disinfecting the microorganisms inside the tank assembly 1, preventing the residue of microorganisms inside the tank assembly 1. The used air is discharged from the discharge pipe 5.
