Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-clogging inoculation and feeding needles, and more particularly to an anti-clogging inoculation and feeding needle for a fermenter. Background Technology
[0002] In microbial fermentation production, the safe inoculation of the seed culture is crucial throughout the entire fermentation process. However, in actual production, the inoculation needle is often blocked by punctured rubber fragments, affecting the normal inoculation process and reducing the fermentation success rate. To solve the problem of needle blockage, a new anti-blocking inoculation needle for fermentation is needed to replace the existing needles. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide an anti-clogging inoculation and feeding needle for a fermenter, including a needle body and a tank connecting nut; the needle body includes a stainless steel hollow needle tube, an inlet hole, and an outlet hole; the inlet hole is connected to the seed bottle through a flexible tube; the needle is inserted into a sealing rubber gasket at the inoculation port of the fermenter; the connecting nut is connected to the seed tank threaded joint; the seed liquid is pumped into the fermenter through the inoculation needle by a peristaltic pump from the outlet hole.
[0004] The main body of the needle is a stainless steel needle, which is hollow and nail-shaped, with a conical tip.
[0005] The liquid outlet is opened from the side and is located on the oblique cut surface of the conical needle.
[0006] The liquid outlet holes are arranged in a circular array, with one or more of them.
[0007] The beneficial effects of this utility model are as follows:
[0008] Two or more outlet holes are located in the center of the side cut surface of the conical needle. Compared with ordinary oblique needles, the stress between the outlet holes on both sides of the conical needle and the rubber stopper is smaller, making it less prone to clogging. Attached Figure Description
[0009] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0010] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation
[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0012] See Figure 1 .
[0013] The fermentation tank is a conventional existing structure and is not an innovative improvement in this case, so its structure will not be described in detail.
[0014] The utility model discloses a kind of inoculation feeding plug pins of fermentation tank anti-blocking, including plug pin main body 1 and jar body coupling nut 2;The plug pin main body and jar body coupling nut;Plug pin main body includes stainless steel hollow needle tube 11, liquid inlet hole 12, liquid outlet hole 13;Liquid inlet hole is connected with seed bottle by hose;Plug pin inserts the sealing rubber gasket of fermentation tank inoculation mouth;Coupling nut is connected with seed jar screw thread;Seed liquid is punched into fermentation tank from liquid outlet hole by inoculation plug pin through peristaltic pump.
[0015] Plug pin main body is stainless steel needle, shape is hollow nail shape, needle head 111 is conical.
[0016] Liquid outlet hole 13 is side opening, located on conical needle head chamfer.
[0017] The liquid outlet hole 13 is circular array, and more than one is provided.
[0018] The use of such plug pin is: seed fermentation tank inoculation plug pin;Fermentation tank feeding plug pin and alkali and acid supplementing plug pin.
[0019] The above-mentioned is only the embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent transformation or direct or indirect application in related technical field using the contents of the utility model specification and drawings is also included in the patent protection range of the utility model.
