Description

Technical Field

[0001] The utility model relates to the technical field of bioreactors, and more specifically to a bionic peristaltic reactor. Background Art

[0002] The rumen is the natural fermentation tank with the strongest known ability to degrade fiber. The contraction of the rumen is also called rumen peristalsis. It is an activity that is carried out by alternating contraction and relaxation of longitudinal muscles and circular muscles. The movement process is slow and powerful. The movement of the rumen is related to the myoelectric potential of its smooth muscles. In the gastrointestinal tract of ruminants, there are a large number of smooth muscle tissues. These muscle tissues have spontaneous contraction ability and can produce peristaltic movement when stimulated. This peristaltic movement helps to mix and push food in the gastrointestinal tract, promoting digestion and absorption of food.

[0003] A bioreactor is a reaction device designed to simulate the functions of organisms in vitro and used to produce or detect various chemicals. In other words, a bioreactor is a device system that uses the biological functions of enzymes or organisms to perform biochemical reactions in vitro. It is a biological function simulator, such as a fermenter, immobilized enzyme or immobilized cell reactor.

[0004] However, existing bioreactors are usually composed of numerous mechanical structural components, which do not simulate the functions of organisms well, affecting the accuracy of producing or detecting chemicals.

[0005] Therefore, providing a bionic peristaltic reactor with good simulation effect is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the utility model provides a bionic peristaltic reactor, which can better simulate the movement in the organism and provide an environment more suitable for the growth and reaction of microorganisms.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A bionic peristaltic reactor comprises a tank body, a filter membrane, an electrodeformable film and a drive device, wherein the flexible wall on the inner surface of the tank body, the filter membrane and the electrodeformable film are connected as a whole in sequence from the outside to the inside; and the drive device is electrically connected to the electrodeformable film through an electrode wire.

[0009] By adopting the above technical solution, the beneficial effects of the utility model are:

[0010] By applying voltage through the driving device, under the action of the electric field, the electrodeformable film deforms to produce contraction and expansion movements, thereby driving the flexible wall to creep and push the material forward. Combining electrodeformation technology with bionic design can better simulate the movement in organisms and provide an environment more suitable for the growth and reaction of microorganisms.

[0011] Furthermore, the flexible wall is in a wrinkled shape.

[0012] The beneficial effect of adopting the above further technical solution is to increase the contact area.

[0013] Furthermore, the tank body is a spherical cavity; one side of the tank body close to the top has a feed inlet and an air outlet, and the other side of the tank body close to the top has a discharge port; and the bottom of the tank body has a filtrate outlet.

[0014] Furthermore, the tank body is made of silicone rubber.

[0015] Furthermore, a support frame is installed at the bottom of the tank body.

[0016] Furthermore, the electrodeformable film comprises two electrodeformable layers which are connected as a whole from outside to inside, and the electrode arrangement directions of the two electrodeformable layers differ by 45 degrees; and the driving device is electrically connected to the two electrodeformable layers respectively.

[0017] Furthermore, the electrodeformable film includes a first electrode layer, a deformation layer and a second electrode layer which are connected as a whole in sequence from the outside to the inside; the filter membrane is adhered to the first electrode layer; and the driving device is electrically connected to the first electrode layer and the second electrode layer respectively.

[0018] Furthermore, the materials of the first electrode layer and the second electrode layer are both graphene; and the material of the deformable layer is silicone or polyurethane.

[0019] Furthermore, the filter membrane is a carbon nanotube composite ultrafiltration membrane.

[0020] Furthermore, the driving device includes a power supply, a power amplifier and a controller which are electrically connected in sequence, and the power supply is electrically connected to the electrodeformable film through the electrode wire.

[0021] The beneficial effect of adopting the above-mentioned further technical solution is that the power supply provides an appropriate voltage, the power amplifier amplifies the voltage signal to a suitable voltage range for use by the electrodeformable film, and the controller is used to control the voltage and frequency of the electric field, so that the electrodeformable film produces periodic contraction and expansion, thereby driving the flexible wall to produce a creeping effect.

[0022] It can be seen that the utility model provides a bionic peristaltic reactor. Compared with the prior art, the utility model:

[0023] 1) Strong controllability: Electrodeformation creep can achieve precise control of material deformation and movement by adjusting the applied electric field parameters.

[0024] 2) Good repeatability: Electrodeformation peristalsis is based on the action of electric field on materials, so the same electric field conditions can be repeatedly applied to achieve repeated peristaltic motion simulating the rumen.

[0025] 3) No mechanical transmission: Electrodeformation creep does not require mechanical transmission devices, thus avoiding the friction, wear and failure problems that may occur in traditional creep mechanisms, which reduces the need for maintenance and repair and improves the reliability and stability of the system.

[0026] 4) From a bionic perspective, constructing a microbial culture environment outside the animal body can allow rumen anaerobic fungi to reproduce in an artificial environment, making the process of microbial degradation of corn stalk bark spontaneous and sustainable, reducing the production cost of cellulosic ethanol, making it simple and feasible and suitable for industrial production.
