Description

Technical Field

[0001] The utility model relates to the technical field of fermentation devices, in particular to a fermentation device for producing cellulase. Background Art

[0002] Cellulase (β-1,4-glucan-4-glucan hydrolase) is a general term for a group of enzymes that degrade cellulose to produce glucose. During the cellulase fermentation process, the pressure in the existing fermentation device increases due to the sealed state. In order to avoid the problem of explosion caused by excessive pressure inside the tank, a cellulase fermentation device with pressure relief has been developed.

[0003] The existing patent (publication number: CN216890959U) discloses a cellulase fermentation device, which can detect the pressure inside the fermentation tank through a pressure sensor. Since the pressure inside the fermentation tank is in a sealed state, the pressure increases. When it exceeds the tolerance of the fermentation tank, the exhaust box is started to make the fan ventilate, and the sealing cover is opened to discharge the gas in the fermentation tank from the upper end of the exhaust box to reduce the air pressure in the fermentation tank.

[0004] However, the above-designed cellulose fermentation device still has some shortcomings in practical applications: for example, although the above-designed cellulose fermentation device can achieve the purpose of pressure relief, it needs to be used in conjunction with an internally arranged pressure sensor, and the pressure sensor is a precision electronic device, which results in the pressure sensor not only needing to be powered on for a long time during use, but also needing to ensure that the pressure sensor does not malfunction, and this technology is relatively cumbersome.

[0005] Therefore, we designed a fermentation device for producing cellulase to solve the above problems. Utility Model Content

[0006] The utility model provides a fermentation device for producing cellulase. When the material produces more carbon dioxide during the fermentation process, the gas in the fermentation tank will push the blocking ball to move upward in the fixed hole because the gas pressure is greater than the external air pressure. In this process, the blocking ball drives the connecting piece and the sliding piece to move upward in the fixed frame, which facilitates the connection between the fermentation tank, the fixed hole and the exhaust hole, thereby facilitating the discharge of carbon dioxide to the outside, avoiding the problem of explosion due to the high air pressure in the fermentation tank, improving the safety, and also improving the fermentation effect, and solving the problems raised in the background technology.

[0007] In order to solve the above technical problems, the utility model provides a fermentation device for producing cellulase, including a fermentation tank, a cover body movably connected to the top of the fermentation tank, a fixing hole is opened in the cover body, a fixing frame is fixedly arranged on the top of the cover body, a sealing ball is movably arranged in the fixing hole, a sliding part is slidably arranged in the fixing frame, a connecting part is arranged at the bottom of the sliding part, the other end of the connecting part is fixedly connected to the sealing ball, an exhaust hole is opened on one side of the cover body, and the fermentation tank, the cover body and the exhaust hole are connected.

[0008] Preferably, a cavity is provided at the bottom of the fixing frame, the cavity is communicated with the fixing hole, the sliding piece is slidably connected in the cavity, and the connecting piece is slidably inserted in the fixing hole.

[0009] Preferably, a guide rod is inserted into the slide, and both ends of the guide rod are fixedly installed in the cavity. A return spring is movably sleeved on the guide rod, and both ends of the return spring are fixedly connected to the slide and the inner wall of the cavity respectively. When the pressure in the fermentation tank is balanced with the external environment, the return spring pushes the slide to move downward along the direction of the guide rod and reset due to its own elastic force, so that the fixed hole can be sealed again to avoid air leakage.

[0010] Preferably, there are two guide rods, and the two guide rods are symmetrically inserted into the slide. The arrangement of the two guide rods can improve the sliding stability of the slide and avoid the problem of the slide tilting when sliding.

[0011] Preferably, a fixed cylinder is provided on one side of the cover body, an air guide tube is fixedly inserted on one side of the fixed cylinder, the air guide tube is movably inserted in the exhaust hole, an exhaust port is opened on the other side of the fixed cylinder, and a purification component is provided in the fixed cylinder for purifying the gas discharged from the fermentation tank. Before carbon dioxide is discharged to the outside of the fermentation tank through the exhaust hole, it will first enter the fixed cylinder through the air guide tube, and then be filtered, adsorbed and purified by the purification component, so that the irritating smell is reduced, thereby avoiding discomfort to people around.

[0012] Preferably, the purification component includes a filter screen, filter cotton and a vanilla layer, and the filter screen, filter cotton and vanilla layer are all fixedly arranged in a fixed cylinder.

[0013] Preferably, a threaded hole is provided in the exhaust hole, and an external thread is provided on the outer surface of the air guide tube. The air guide tube is inserted into the threaded hole through the external thread. When the purification component in the fixed cylinder is blocked, the fixed cylinder can be rotated to drive the air guide tube to screw out of the threaded hole, so that the fixed cylinder can be easily replaced to clean the purification component in the fixed cylinder.

[0014] Preferably, an elastic pad is fixedly mounted on the cover body, the elastic pad abuts against the outer surface of the fermentation tank, and the elastic pad is made of fluororubber, which can fill the small gap between the fermentation tank and the cover body, thereby improving the sealing effect. In addition, the elastic pad is set to fluororubber, and since fluororubber has good high temperature resistance, the elastic pad can be used normally in a high temperature environment.

[0015] Compared with the related art, the fermentation device for producing cellulase provided by the utility model has the following beneficial effects:

[0016] 1. In the utility model, when the material produces more carbon dioxide during the fermentation process, the gas in the fermentation tank will push the blocking ball to move upward in the fixed hole because the gas pressure is greater than the external air pressure. In this process, the blocking ball drives the connecting piece and the sliding piece to move upward in the fixed frame, which is convenient for connecting the fermentation tank, the fixed hole and the exhaust hole, so as to facilitate the discharge of carbon dioxide to the outside, avoid the problem of explosion due to the high air pressure in the fermentation tank, improve safety, and also improve the fermentation effect.

[0017] 2. In the utility model, through the cooperation of the fixed cylinder, the air duct, the exhaust port and the purification component, before the carbon dioxide is discharged to the outside of the fermentation tank through the exhaust hole, it will first enter the fixed cylinder through the air duct and be filtered, adsorbed and purified by the filter screen, filter cotton and vanilla layer, so as to reduce the irritating smell and avoid making people around feel uncomfortable. When the purification component in the fixed cylinder is blocked, the fixed cylinder can be rotated to make the fixed cylinder drive the air duct to screw out of the threaded hole, so that the fixed cylinder can be easily replaced to clean the purification component in the fixed cylinder.
