Abstract

A discloses a desilting equipment of methane tank includes a screw lifting device where an impeller is provided at the bottom. The screw lifting device and the impeller are installed on the same drive shaft powered by an electric engine. The screw lifting device consists of a shell and a screw lifting impeller which is fixed on the drive shaft and positioned inside the shell with the drive shaft connected to the shell flexibly; a feed inlet is provided on the shell; the inner diameter of the shell is from 7 mm to 20 mm; and at least two screw lifting blades are provided on the screw lifting impeller, which screw in the same direction as the blades on the impeller. The utility model is used to effectively clean the residue silted at the bottom of the methane tank. As the diameter of the shell can be made smaller, the utility model is small, skillful and light in the whole structure. Thereby preservation of only a small hole is needed on the top of the methane tank. Being convenient in use, time-saving and labor-saving, the utility model reduces the use cost and improves the service efficiency of the methane tank.

Description

The methane-generating pit Accrete clearing device

Technical field

The utility model relates to the methane-generating pit Accrete clearing device.

Background technology

The existing methane-generating pit residue that in use back produces because the organism in the pond rots is deposited at the bottom of the pond, time has been grown and will deposit, and viscosity is very big, can't discharge naturally from discharge port, must be with the water emptying in the methane-generating pit, by means of instrument, the residue of alluvial is dug up, otherwise methane-generating pit just can't continue to use.Waste time and energy, strengthened use cost, influenced service efficiency, the methane-generating pit that has even owing to can't desilting damaging.

The utility model content

The purpose of this utility model is to provide a kind of methane-generating pit Accrete clearing device that can easily alluvial be removed at the residue of methane-generating pit bottom.

Solution of the present utility model is: contain the spiral lifting gear, in the bottom of spiral lifting gear impeller has been installed, spiral lifting gear and impeller are installed in by on the motor-driven same drive shaft.

The structure of spiral lifting gear is: contain guide and spiral and promote impeller, spiral promotes impeller and is fixed on the drive shaft, and places the guide inner chamber, and drive shaft and guide flexibly connect, and guide is provided with opening for feed.

The internal diameter size of guide is the 7-20 millimeter.

Spiral promotes has at least 2 spirals to promote blade on the impeller.

Spiral promotes spiral on the impeller, and to promote the hand of spiral of the blade on blade and the impeller identical.

After adopting the utility model, can remove the residue of alluvial effectively in the methane-generating pit bottom, because it is very little that the diameter of guide can be accomplished, therefore, one-piece construction is small and exquisite, light, only needing to reserve a very little hole on methane-generating pit top gets final product, easy to use, time saving and energy saving, desilting speed is fast, reduce use cost, improved the service efficiency of methane-generating pit.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:

Contain guide 6 and spiral and promote impeller 8, spiral promotes impeller 8 and circumferentially is fixed on the drive shaft 5 by key, spiral promotes the axial restraint of impeller 8 on drive shaft 5 and is finished jointly by retreat stop block 7 and cover 9, spiral promotes has 3 spirals to promote blade on the impeller 8, spiral promotes impeller 8 and places guide 6 inner chambers, the internal diameter size of guide 6 is 10 millimeters, the upper end of guide 6 is an opening, fixedly connected with carrier pipe 3 in the top of guide 6, discharge port 4 is arranged at the top of carrier pipe 3, the dual-side of guide 6 is provided with opening for feed 11, shrouding 13 is equipped with in the lower end of guide 6, on the shrouding 13, downside has been installed bearing 10 respectively, 12, cover 9 is against on the bearing 10 bearing 10,12 are installed on the drive shaft 5, on the drive shaft 5 of bearing 12 belows impeller 15 has been installed, impeller 15 is axially fixed on the drive shaft 5 with bearing 12 by piecing together cap 14, and drive shaft 5 is connected by shaft coupling 2 with the output shaft of motor 1, and the hand of spiral of the blade on the spiral lifting blade on the spiral lifting impeller 8 and the impeller 15 is identical.

During use, guide 6 and spiral are promoted the spiral lifting gear insertion alluvial of impeller 8 compositions in the residue of methane-generating pit bottom, start motor 1, allow motor 1 reverse earlier, the residue of 15 pairs of alluvials of impeller in the methane-generating pit bottom stirred fully, dilution, to promote the hand of spiral of the blade on blade and the impeller 15 identical because spiral promotes spiral on the impeller 8, so, the spiral lifting gear that guide 6 and spiral lifting this moment impeller 8 is formed does not extract operation to the residue of alluvial in the methane-generating pit bottom, wait that the residue that deposits in the methane-generating pit bottom stirs through sufficient, after the dilution, allow motor 1 just change again, then through stirring, the residue of the methane-generating pit bottom after the dilution enters in the guide 6 through the opening for feed 11 of guide 6 dual-sides, promote impeller 8 through spiral again the residue of these methane-generating pits bottoms risen in the carrier pipe 3, after the discharge port 4 on carrier pipe 3 tops send.
