Description

Continuous feeding and taking fermentation device

Technical Field

The utility model relates to a fermenting installation, concretely relates to advance in succession and get material fermenting installation.

Background

The raw materials such as the bean curd residue, the cassava residue, the vinasse, the agricultural product processing leftovers and the like are good feed raw materials for livestock and poultry breeding industry, the nutritional value is high, compared with corn, bean pulp and the like, the raw materials have the advantages of low cost and good feeding effect, however, the raw materials have substances which are not good for the health of livestock and poultry, for example, fresh bean curd residue contains anti-nutritional factors, the cassava residue contains a small amount of toxic substances such as hydrocyanic acid and the like, and the vinasse contains residual alcohol and the like, so the raw materials can be used as the feed for livestock and poultry after fermentation.

In the prior art, a plurality of small water jars are generally adopted for small-scale fermentation operation of feed raw materials, one empty water jar is used for hermetically storing and fermenting the raw materials to be fermented when feeding every day, and the water jar after fermentation for a preset time is opened for taking the raw materials when taking the raw materials. Because the opening of the water vat is small, the material taking from the water vat is not assisted by equipment at present, the whole process is manually dug, and the fermentation inoculum needs to be added in proportion for each batch of material feeding, so the operation is inconvenient and is not suitable for large-scale operation.

In addition, no matter the water vat or the cement pond or the ensiling pond is adopted for fermentation, the fermented materials in one vat or one pond cannot be taken or filled at each time due to the problem of different stage demands in production, the residual space in the water vat or the pond is too large after the fermented materials in the water vat or the pond are taken or only part of the raw materials are filled, and the raw materials are easy to rot due to too much internal air. For the water vat, because it can only get the material through the opening at the water vat top, if take part fermentation material in the water vat and fill new raw materials that wait to ferment to the water vat after, it can solve the inside air of water vat too much and lead to the easy rotten problem of raw materials, however, because get the material from the top opening of water vat among the prior art usually, therefore, can usually take the fermentation material that is located the fermentation time of water vat short away to use when getting the material next time, and the fermentation material that is located the water vat bottom is easily rotten because of the fermentation time overlength. Therefore, in the prior art, a plurality of fermentation tanks are usually required to be arranged according to the fermentation batch, the raw materials can be put into the fermentation tanks again for fermentation after the raw materials fermented in the same batch are used up, the fermentation bacteria agent is added in proportion in each fermentation, and the continuous feeding and continuous fermentation of the water tank cannot be realized.

When the continuous feeding and taking fermentation device 100 is used, the feeding pipe 4 is arranged at the top of the storage tank 2, the taking port 22 is arranged at the bottom of the storage tank 2, feeding is carried out from the feeding pipe 4 positioned at the top of the fermentation space 26 during feeding, and taking is carried out from the taking port 22 at the bottom of the storage tank 2 during taking, so that the taken fermentation material is the raw material with the longest fermentation time, the fermentation time of the raw material can be ensured, and the raw material can be prevented from being rotten due to overlong fermentation time. Because it can ensure that the fermentation material that takes out is the raw materials that the fermentation time is the longest, consequently, when the fermentation, can be to continuous feeding in storage jar 2, it is more convenient to use.

Above-mentioned advancing in succession and getting material fermenting installation 100 still includes agitator 10, because above-mentioned advancing in succession and getting material fermenting installation 100 can be to the continuous feeding in storage jar 2, consequently, add the storage jar 2 back with new raw materials, accessible agitator 10 mixes new material and old material, makes to possess a large amount of fermentation bacterial in the storage jar 2, need not to throw the fermentation inoculum after reinforced at every turn, can reduce the use amount of fermentation inoculum, reduces fermentation cost.

Above-mentioned continuous feeding and taking fermenting installation 100 is in encapsulated situation when the fermentation, seals material taking port 22 through ejection of compact control valve 25, and is sealed effectual, and the sewage that produces among the fermentation process can not be discharged to the external world, and then can not the polluted environment, also can reduce the nutritive loss of raw materials.

Above-mentioned continuous feeding and taking fermenting installation 100, the fermentation material of jar body 23 bottom is followed the material of getting 22 and is derived outside jar body 23 through spiral ejection of compact auxiliary mechanism 9 is automatic during its ejection of compact, need not the manual work and digs the material, can further reduce intensity of labour, and it is more convenient to use.

It is understood that the structure of the lifting mechanism 5 is not limited to this embodiment, and other lifting devices in the prior art may be adopted as long as the sealing piston 5 can be driven to move up and down.

It is understood that the structure of the feed pipe 5 is not limited to this embodiment, for example, in other embodiments, the feed pipe 5 may be a rigid pipe, and the feed pipe 5 may be connected to the temporary storage hopper 71 by a hose, a flexible bellows, or the like, and may also allow the sealing piston 3 to move up and down relative to the temporary storage hopper 71 without changing the position of the temporary storage hopper 71. It will be appreciated that the feed pipe 5 may also be a rigid pipe, in which case the buffer hopper 71 may move with the feed pipe 5 and the sealing piston 3.

The above description is for the detailed description of the preferred possible embodiments of the present invention, but the embodiments are not intended to limit the scope of the present invention, and all equivalent changes or modifications accomplished under the technical spirit suggested by the present invention should fall within the scope of the present invention.
