Abstract

A double-twisted-cutter crushing type biogas slurry and residue pump belongs to a pump. The main shortcoming that the current natural pond liquid natural pond sediment pump exists because of the cutter body can not carry out the breakage to the sediment and the rotational speed of motor can not reach rated revolution fast and lead to the suction in-process to produce the jam and need the base of whole change wearing and tearing. The utility model discloses an open the pump body that has feed inlet and discharge gate, with pump body coupling' S base, be located the pump body and have the motor of pivot, the cutter body of being connected with the pivot, the blade on its characterized in that cutter body is the S-shaped, and two blades are the cross arrangement each other. The utility model has the advantages of simple structure, strong crushing capability, good cleaning effect, high working efficiency and convenient use.

Description

Double reamer crushing biogas slurry and residue pump

technical field

The utility model belongs to a suction and drainage pump, in particular to a biogas slurry and biogas residue suction and drainage pump used for cleaning sediment in a biogas pool.

Background technique

The currently used biogas slurry and biogas residue pumps have the following deficiencies: 1. Since the blade on the cutter body is a spiral structure, it can only stir or tear the sediment, but cannot break the sediment. Therefore, it is easy to It will lead to the clogging of the suction pump during the suction process, which will cause equipment damage in severe cases; 2. The speed of the motor cannot reach its rated speed at a faster speed, which also causes the clogging of the suction pump during the suction process One of the reasons; 3. The worn base needs to be replaced as a whole, which increases the cost of use. Moreover, it is precisely because of the reasons of the first and second points above that the suction pump can only be placed in the middle of the liquid in the biogas digester to work, which seriously affects the cleaning effect of the biogas slurry and residue.

Contents of the invention

The purpose of this utility model is to provide a double reamer crushing biogas slurry and biogas slag pump with simple structure, strong crushing ability, good cleaning effect, high working efficiency and convenient use.

位于泵体内且带有转轴的电机、与转轴连接的刀体，其特征在于所说刀体上的刀片为S形，且两片刀片相互呈十字形排列。The utility model is achieved in the following way: it includes a pump body with a feed port and a discharge port, and a base connected to the pump body

A motor with a rotating shaft located in the pump body and a cutter body connected to the rotating shaft are characterized in that the blades on the cutter body are S-shaped, and the two blades are arranged in a cross shape.

The outer surfaces of the above two S-shaped blades are also provided with a layer of reverse S-shaped concentric short-headed blades.

Said motor is also provided with a motor accelerator that can make the rotating shaft of the motor rotate rapidly in an instant.

The upper part of the base is provided with an adjustable friction disc, wherein the adjustable friction disc is provided with a feeding hole which can communicate with the feeding port of the pump body.

The cutter body of the utility model is in the form of a double twisted cutter with a two-layer structure, wherein the inner layer is two S-shaped blades arranged in a cross shape, and the outer layer is a reverse S-shaped concentric short-head blade, which has strong anti-slag crushing ability. The additional motor accelerator can make the motor reach the rated speed instantly, so as to crush the sediment as soon as possible. In a word, because there will be no blockage, the utility model can be placed on the liquid bottom of the biogas tank to work, so that the biogas slurry and residue can be directly and thoroughly cleaned. After the adjustable friction disc installed on the upper part of the base is worn out, only the adjustable friction disc can be replaced to avoid replacing the entire base, thereby reducing the use cost. The utility model has the advantages of simple structure and convenient use.
