Description

Technical Field

[0001] This utility model relates to the field of trencher technology, specifically a guide plate structure for fermenters. Background Technology

[0002] Fermenters are one of the most important pieces of equipment in bioengineering. They provide an ideal environment for the growth and reproduction of microorganisms, that is, a container that provides a good environment for the operation of a specific biochemical process of microorganisms.

[0003] During the use of a fermentation tank, the material to be fermented and the fermenting agent need to be placed in the fermentation tank together. In a conventional fermentation tank, in order to ensure sufficient contact and reaction between the substances, a stirring shaft is installed in the tank to accelerate the flow of substances in the tank, thereby improving fermentation efficiency. However, all of these can only be done after all the substances have been completely added to the tank to ensure the normal ratio between the substances. This causes the substances to concentrate in a certain area of ​​the tank after entering it, resulting in the process of complete mixing and contact between the substances requiring more time to be stirred.

[0004] Therefore, a baffle structure for fermenters is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a guide plate structure for fermenters, which can solve the problem of low fermentation efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a guide plate structure for a fermenter, comprising a disc, an opening in the middle of the disc, and the middle of the disc being inclined downwards to make the whole disc funnel-shaped, and an annular baffle installed along the edge of the disc.

[0007] A limiting plate is vertically installed on the top surface of the disc. The limiting plates are arranged in a spiral pattern on the top surface of the disc. Multiple through holes are opened on the disc. The through holes are arranged at intervals along the spiral pattern, and the frontal projection of the through holes is located between adjacent limiting plates.

[0008] Preferably, an annular support plate is provided along the top outer wall of the baffle.

[0009] Preferably, multiple spaced, arc-shaped slots are provided along the support plate.

[0010] Preferably, sealing rings are installed on both the upper and lower sides of the bearing plate.

[0011] Preferably, a strip groove is provided in the middle of the disc, and the strip groove is provided through the baffle and the support plate, dividing the disc, baffle and support plate into two symmetrical arc plates. A connecting plate is installed at the bottom of the side of the arc plate near the strip groove, and the connecting plates on the two arc plates are fixed together by bolts.

[0012] Preferably, a guide shaft is vertically installed on one side of one arc-shaped plate near the other arc-shaped plate, while a guide groove corresponding to the guide shaft is formed on the side of the other arc-shaped plate.

[0013] Preferably, arc-shaped clamps are coaxially installed on both sides of the inner wall of the opening, with the clamps corresponding to the arc-shaped plates, and crescent bearings are installed on the inner wall of the clamps.

[0014] Compared with the prior art, this utility model provides a guide plate structure for fermenters, which has the following beneficial effects:

[0015] 1. This utility model uses a vortex-shaped limiting plate to guide the material falling on the disc and converging towards the opening, so that the material flows towards the opening in a vortex shape. In conjunction with the through holes on the disc, the flowing material falls from multiple through holes separately, so that the material falls into the fermentation tank in a dispersed manner, so as to facilitate the subsequent stirring and mixing of the materials and improve the fermentation efficiency.

[0016] 2. This utility model is made up of two symmetrical arc-shaped plates, which facilitates the installation of the disc in the fermentation tank and will not be obstructed by the stirring shaft in the fermentation tank. Attached Figure Description

[0024] 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.

[0025] Example:

[0026] Please see Figure 1 - Figure 6 In this embodiment, a guide plate structure for a fermenter includes a disc 1. The middle part of the disc 1 is inclined downward so that it is funnel-shaped. An annular baffle 2 is installed along the edge of the disc 1. After the material falls on the disc 1, it can slide along the disc 1 toward the middle part, providing power for the flow of the material on the disc 1.

[0027] A ring-shaped support plate 10 is provided along the top outer wall of the baffle 2. In actual use, the fermentation tank (such as...) Figure 6 The location indicated by the middle arrow A includes the tank body and the top cover with an open top. The stirring shaft is coaxially mounted on the bottom of the top cover. When installing the disc 1, the support plate 10 is placed at the flange connection between the tank body and the top cover of the fermentation tank. Multiple spaced and arc-shaped slots 11 are provided on the support plate 10 so that when the tank body and the top cover are fixed by the flange, the bolts on the flange can pass through the slots 11 to prevent the support plate 10 from obstructing the connection and installation between the tank body and the top cover.

[0028] Furthermore, in order to ensure that the addition of the support plate 10 does not affect the sealing performance of the fermenter, sealing rings 12 are installed on both the upper and lower sides of the support plate 10. As the tank body and the top cover approach each other, the sealing rings 12 are clamped and squeezed, thereby filling the gaps between the support plate 10 and the tank body, and between the support plate 10 and the top cover, thus sealing the upper and lower sides of the support plate 10.

[0029] Specifically, since a stirring shaft is installed at the bottom of the top cover, and to ensure that the installation of the disc 1 inside the fermentation tank is not affected, a strip groove 8 is provided in the middle of the disc 1. The strip groove 8 passes through the baffle 2 and the support plate 10, dividing the overall structure composed of the disc 1, baffle 2, and support plate 10 into two symmetrically arranged arc-shaped plates. In this way, the two arc-shaped plates can be taken out and joined together from both sides of the top of the tank to complete the installation. An opening 3 is provided in the middle of the disc 1, which corresponds to the stirring shaft. Therefore, it is beneficial to install the disc 1 on the top of the tank without affecting the setting of the stirring shaft.

[0030] During operation, use a lifting tool to lift the top cover and move it above the tank body. Then, place the stirring shaft under the top cover inside the tank body. Before the top cover and tank body are joined, take the curved plate and join them from the top two sides of the tank body. Then, place the joined curved plate on the top of the tank body. Finally, put the top cover on to fix it and complete the installation.

[0031] After the curved plates are combined, a connecting plate 9 is installed at the bottom of the side of the curved plate near the strip groove 8, and the connecting plates 9 on the two curved plates are fixed together by bolts to reinforce the two curved plates, reduce the size of the gap between the two curved plates, and prevent the material from flowing directly out of the strip groove 8 after falling on the disc 1.

[0032] In addition, such as Figure 1 and Figure 4 As shown, arc-shaped clamping plates 6 are coaxially installed on both sides of the inner wall of the opening 3. The clamping plates 6 correspond to the arc-shaped plates. A crescent bearing 7 is installed on the inner wall of the clamping plate 6. After the two arc-shaped plates are combined, the clamping plate 6 will approach the stirring shaft, that is, the inner wall of the crescent bearing 7 will be attached to the stirring shaft. While limiting and supporting the stirring shaft, it also ensures the normal rotation of the stirring shaft.

[0033] Furthermore, such as Figure 4 and Figure 5 As shown, a guide shaft 13 is vertically installed on one side of the curved plate near the other curved plate, while a guide groove 14 corresponding to the guide shaft 13 is opened on the side of the other curved plate, providing guidance for the alignment and installation between the two curved plates, so that the two curved plates can be completely spliced ​​together.

[0034] After completing the installation of disc 1 inside the fermentation tank, as follows Figure 1 and Figure 3As shown, a limiting plate 4 is vertically installed on the top surface of the disc 1. The limiting plate 4 is arranged in a vortex pattern on the top surface of the disc 1. Multiple through holes 5 are opened on the disc 1. The through holes 5 are arranged at intervals along the vortex pattern, and the frontal projection of the through holes 5 is located between adjacent limiting plates 4. When materials are added into the fermentation tank, the materials fall from the feed inlet of the fermentation tank onto the disc 1 and begin to slide towards the opening 3 on the disc 1. During this process, the materials are obstructed by the limiting plates 4, so that the materials can only flow in a vortex pattern along the side wall of the limiting plates 4 on the disc 1 until the materials come into contact with the through holes 5. The materials that come into contact with the through holes 5 will fall from the through holes 5, while the materials that do not come into contact with the through holes 5 will continue to flow until they come into contact with the through holes 5. Therefore, due to the vortex pattern of the through holes 5 on the disc 1, the materials can fall into the fermentation tank in a dispersed manner, reducing the concentrated deposition between materials and affecting the efficiency of subsequent stirring and mixing.

[0035] It should be noted that in actual use, the through holes 5 are arranged adjacently in the central area near the disc 1, that is, there are many through holes 5 near the center of the disc 1, so as to ensure that the material does not settle on the disc 1, thereby causing errors in the mass ratio between materials and affecting the fermentation process.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
