Description
Technical field
The utility model belongs to biogas engineering device technical field, especially a kind of clear water return channel.
Background technique
Large-sized biogas fermentor generallys use complete hybrid fermentor, agricultural crop straw after crushing with water or natural pond
Liquid is used as raw material after mixing according to a certain percentage, is added in fermentation tank and carries out sealed fermenting and generate biogas.By
A large amount of test is drawn a conclusion, and it is optimum formula that solid biomass raw material, which accounts for 10% ratio, in fermentor.
It needs to be sufficiently mixed into crushed biomass and liquid phase in pretreatment tank before adding raw materials in king's fermentor
Then mixed raw material is pumped in fermentor by industrial pump by solid-liquid mixed raw material again.The industrial pump of the prior art conveys this
Solid-liquid mixed raw material is planted, otherwise ratio shared by solid material is easy for blocking industrial pump no more than 7%, cannot be normal complete
At conveying operation.
As shown in Figure 1, to solve the above-mentioned problems, the applicant devises a clear water return channel 1 ', clear water is flowed back
Device 1 ' is mounted on the output pipe of industrial pump 2 ', and clear water return channel 1 ' distributes a part of clear water and returned to by return line
Pre-process that tank 3 ' is interior, clear water return channel 1 ', which distributes the solid-liquid mixed raw material concentration after a part of clear water, increases to design requirement
Concentration to be transported to fermentor 4 ' interior.In the prior art, not similar clear water return channel can be applied.
Summary of the invention
The purpose of this utility model is to provide a kind of clear water return channels, it has, and structure is simple, performance is stable, solves
Solid-liquid mixed raw material transportation problem in biogas project.
Technical solution used by the utility model is achieved in that a kind of clear water return channel, it is characterised in that: it is wrapped
Four-way tube body is included, the left mouth of four-way tube body is water inlet, and the right mouth of four-way tube body is water outlet, and mouth is spare mouth under four-way tube body, four
Siphunculus body suitable for reading is refluxing opening, and spare mouth is blocked by spare mouth blind flange, and disc-type filter screen is successively installed above refluxing opening, is returned
Flow tube body, reflux tube body lid, sealing ring, spring strut, bearing, bearing block, motor cabinet and motor；Vertical shaft is installed on bearing, is stood
Axis upper end connects motor output shaft, and vertical shaft lower end passes through disc-type filter screen centre bore and scrapes web plate with below disc-type filter screen
It connects, spring of the end branch that is installed on it in spring strut on outer race, the central hole of reflux tube body lid is equipped with ring packing
Slot, annular seal groove is interior to be equipped with sealing ring, and the side for the tube body that flows back connects recycling effluent mouth.
Further, the internal diameter of the inlet and outlet is the 1/2~2/3 of four-way internal diameter of tube body.
Utility model has the advantages that
Installation disc-type filter screen, reflux tube body and recycling effluent mouth above the utility model refluxing opening, it can be distributed
Clear water of a part by filtering is back to pretreatment tank, and the solid-liquid mixing being transported in fermentor from water outlet outflow in this way is former
Material solid phase ratio will increase, and can satisfy the requirement that solid biomass raw material accounts for 10% ratio.
The utility model disc-type filter screen be arranged below be driven by motor scrape web plate, it is stifled to avoid biomass material
The problem of filling in filter screen, work efficiency is high, and working service is all convenient.
In addition, the utility model is simple and reasonable, it is easily worked production, can promote and answer in large-sized biogas engineering
With.
