Abstract
The utility model discloses a discharge port denoising mechanism of a sand pump. The mechanism comprises a pump body. The pump body is provided with a feed port and a discharge port. A ring flange is fixedly disposed on the discharge port of the pump body. A plurality of fine meshes are disposed on the annular end surface of the ring flange. Sound-absorbing cotton is inserted into the fine meshes. The mechanism is simple in structure, delicate in design. The ring flange disposed at the discharge port facilitates assembly between the pump body of the sand pump and the outside world, and assembly efficiency is improved. The sound-absorbing cotton inserted into the fine meshes achieves good denoising effects.
Description
technical field:
The utility model relates generally to Sand pump technical field, relates in particular to a kind of discharge port noise-reducing mechanism of Sand pump.
background technique:
Sand pump is a kind of of sand pump, is applied to large junk more and in river, inhales sand.Sand pump in prior art includes the pump housing, and the pump housing is provided with material feeding mouth and discharge port, and discharge port position straight connected bearing pin and the external world is installed together.So, need first bearing pin with corresponding hole connecting, installation efficiency is lower.
model utility content:
The utility model object is exactly in order to make up the defect of prior art, and a kind of discharge port noise-reducing mechanism of Sand pump is provided, and it be convenient to install, and acoustical cotton has certain noise-reducing effect by flange being set at discharge port position.
The utility model is achieved through the following technical solutions:
A kind of discharge port noise-reducing mechanism of Sand pump, include the pump housing, the described pump housing is provided with material feeding mouth and discharge port, it is characterized in that: the discharge port position of the described pump housing is installed with flange plate, on the annular end face of described flange plate, be distributed with some pores, in described pore, plug is equipped with acoustical cotton respectively.
A discharge port noise-reducing mechanism, it is characterized in that: described flange plate is mounted by means of bolts on the discharge port of the pump housing.
The utility model has the advantages that:
The utility model is simple in structure, designs ingeniously, by flange plate being set at discharge port position, is convenient to the pump housing of Sand pump and extraneous installation, has improved installation efficiency; In pore, plug dress acoustical cotton has good noise-reducing effect.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to accompanying drawing.
A kind of discharge port noise-reducing mechanism of Sand pump, include the pump housing 1, the described pump housing 1 is provided with material feeding mouth 2 and discharge port 3, and discharge port 3 positions of the pump housing 1 are installed with flange plate 4, on the annular end face of described flange plate 4, be distributed with some pores, in described pore, plug is equipped with acoustical cotton 5 respectively.
Flange plate 4 is mounted by means of bolts on the discharge port 3 of the pump housing 1.
