Description

Inlet buffering device of diaphragm pump

Technical Field

The utility model relates to a diaphragm pump buffer, in particular to inlet buffer equipment of a diaphragm pump.

Background

In industries such as alumina, coal chemical industry, hydrometallurgy, can use large-scale reciprocating diaphragm pump usually, set up the import buffer at the import of pump generally, the export of pump sets up the export buffer, carries out the steady voltage and adjusts the flow and fluctuate. The inlet buffer is generally of a cylindrical structure, the upper part and the lower part of the inlet buffer adopt conventional elliptical seal heads, the middle part of the inlet buffer is coiled into a cylinder by a pipe or a plate, and the lower end of the buffer is provided with a slurry inlet, a slurry outlet and a slag discharge port for maintenance. Because solid mixtures such as high-viscosity ore pulp, coal mines or iron powder are conveyed, under the conditions of pump stoppage or pipe blockage, a lower slag discharge hole needs to be opened, and the slurry in the slag discharge hole is washed or manually drawn out.

The pressure-resistant elliptical sealing head is adopted at the lower side of the existing inlet buffer, the depth is a quarter of the inner diameter of the cylinder body generally, the slag discharge port is formed in the cylinder body, and during maintenance, slurry in the elliptical sealing head is difficult to clean, and the situation that the slurry cannot be cleaned often occurs.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide the inlet buffer equipment of the diaphragm pump, which can facilitate the overhaul and the material drawing.

The basic scheme provided by the utility model is as follows: including the buffer body, the buffer body includes upper cover, low head and barrel, feed inlet, discharge gate and row cinder notch have been seted up to the barrel lower extreme, still include the baffle, inside the buffer body was located to the baffle, and was located feed inlet, discharge gate and bin outlet below.

The principle and the advantages of the utility model are as follows: through set up the baffle in buffer body inside, raise the ground of thick liquids. When the slurry scraper is used, slurry is accumulated on the partition plate, and when the slurry scraper is used for overhauling, the slurry on the partition plate is cleaned by opening the slag discharge hole, so that the maintenance and the material drawing are convenient, and the labor intensity during the maintenance is reduced.

Furthermore, the periphery of the partition board is fixedly connected with the inside of the barrel, and a cavity is formed below the partition board.

Ensure that the slurry is totally accumulated on the partition plate.

The air-permeable partition board is characterized by further comprising an air-permeable communicating pipe, wherein a through hole is formed in the partition board, and the air-permeable communicating pipe is communicated with a cavity below the partition board through the through hole.

Through ventilating the communicating pipe, with the pressure balance in buffer body top and the baffle below cavity, make the baffle need not to bear the pressure of equipment, only with the liquid column pressure that bears the thick liquids medium, the pressure that receives is less relatively, and the baffle also can be thinner, and the cost is lower.

Further, the partition plate is a flat plate.

The slurry is convenient to clean.

Further, still include the intake pipe, the intake pipe communicates with buffer body top.

Air is introduced through the air inlet pipe to balance air pressure.

Furthermore, the baffle is positioned above the connecting part of the lower end enclosure and the cylinder body.

Drawings

Fig. 1 is a schematic structural diagram of an inlet buffer device of a diaphragm pump according to an embodiment of the present invention.

Detailed Description

The following is further detailed by way of specific embodiments:

the reference numbers in the drawings of the specification include: the device comprises a cylinder body 1, an upper seal head 2, a lower seal head 3, a feeding hole 4, a discharging hole 5, a slag discharging hole 6, a partition plate 7, an air communicating pipe 8 and an air inlet 9.

The embodiment is basically as shown in the attached figure 1:

the utility model provides an import buffering equipment of diaphragm pump, includes the buffer body, and the buffer body includes upper cover 2, low head 3 and barrel 1, connects through the welded mode, and upper cover 2 and low head 3 are conventional oval head. The lower end of the cylinder body 1 is provided with a feed inlet 4, a discharge outlet 5 and a slag discharge outlet 6. Arrange slag notch 6 and have the complex flap with it, the flap can be dismantled with row slag notch 6 and be connected, through threaded connection in this embodiment, with the flap screw up on row slag notch 6 after, can seal up row slag notch 6 completely, in other embodiments of this application, can also use piston seal row slag notch 6.

Still including baffle 7, baffle 7 is a circular straight board, is located the inside of buffer body to be in the below of feed inlet 4, discharge gate 5 and row cinder notch 6, be located the top of barrel 1 and 3 weldings of low head simultaneously. Baffle 7 all around and the inside fixed connection of buffer body, in this embodiment, connect through the welded mode, form a cavity under the baffle 7. Seted up a through-hole on the baffle 7, still including ventilating communicating pipe 8, ventilating communicating pipe 8 passes through the through-hole, inside cavity and the buffer body of communicating 7 below of baffle, ventilating communicating pipe 8 keeps perpendicular with baffle 7, in this embodiment, the one end of ventilating communicating pipe 8 in the buffer body is inside, is located the welded junction of barrel 1 and upper cover 2, in other embodiments, can adjust according to particular case, as long as when guaranteeing to use, the height of thick liquids can not be higher than ventilating communicating pipe 8. The gas inlet 9 is further included, and the gas inlet 9 is communicated with the top of the upper sealing head 2.

The existing inlet buffer is not provided with the partition plate 7, when high-viscosity ore pulp, coal slurry or iron ore powder and other mixtures are conveyed, the slurry can be accumulated in the lower end enclosure 3 below, the lower end enclosure 3 has a certain depth which is generally one fourth of the diameter of the cylinder body 1, and the slag discharge port 6 is arranged on the cylinder body 1. When clearing up, clear up thick liquids from row cinder notch 6, row cinder notch 6 is far away from the distance of low head 3 bottoms, and the degree of difficulty of clearing up thick liquids is great.

The utility model improves the original inlet buffer, and the bottom surface of the slurry is lifted by arranging the partition plate 7, so that the distance between the slag discharge port 6 and the bottom surface of the slurry is closer, and the slurry is easier to clean. Meanwhile, the pressure in the cavity below the partition plate 7 and the inside of the buffer is balanced through the air communicating pipe 8. The partition plate does not need to bear the pressure of equipment, but only bears the liquid column pressure of the slurry medium, and the liquid column pressure is relatively small, so that the partition plate can be designed to be thin, and the cost is reduced.

The foregoing are merely exemplary embodiments of the present invention, and no attempt is made to show structural details of the utility model in more detail than is necessary for the fundamental understanding of the art, the description taken with the drawings making apparent to those skilled in the art how the several forms of the utility model may be embodied in practice with the teachings of the utility model. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several variations and modifications can be made, which should also be considered as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the utility of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
