Problems solved by technology

Its disadvantages are: 1. The area of ​​the unloading area (that is, the blowing chamber) is reduced, which affects the effect of unloading; 2. Only the area of ​​the filter drying area (that is, the vacuum chamber) is increased without increasing the vacuum connection, which will cause Insufficient vacuum will affect the effect of filtering water
The disadvantages are: 1. Although the adjustment flexibility of the filter drying area has been increased, the area of ​​the filter drying area has not increased, which affects the effect of filtering water; 2. There is no improvement in the discharge area, which affects the effect of discharge

Embodiment 1

[0029] Such as figure 1 As shown, the present invention includes a distribution head housing 1, which is provided with a blowing chamber 2, a vacuum chamber I3, a vacuum chamber II4, and a vacuum chamber III5, and the vacuum chamber II4 and the vacuum chamber III5 are communicated.

[0030] In this embodiment, by connecting the vacuum chamber II4 and the vacuum chamber III5, the angle of the filter dry area is increased from 90° to 180°, which increases the action time of the drum filter dry area and improves the separation rate of water and filter residue.

Embodiment 2

[0032] The difference from Embodiment 1 is that two vacuum tube interfaces 10 are provided on the distribution head housing 1 .

[0033] In this embodiment, compared with the existing distribution head, a vacuum tube interface 10 is added, the vacuum degree of the vacuum chamber II4 and the vacuum chamber III5 is improved, the suction of the drum filter drying area is enhanced, and the separation rate of water is improved. .

Embodiment 3

[0035] The difference from Embodiment 2 is that two blowing holes 9 are provided in the blowing chamber 2 .

[0036] In this embodiment, compared with the existing distribution head, by adding air blowing holes 9 in the air blowing chamber 2, the air pressure in the drum separation area is increased from less than 0.02MPa to between 0.02 and 0.03MPa, and the filter residue is improved. seperate effect.

Abstract

The invention discloses a distribution head of a rotary drum vacuum filter and aims to provide a distribution head of a rotary drum vacuum filter, which has a large filtering angle, high separation rate and high blowing pressure. The distribution head of the rotary drum vacuum filter comprises a distribution head housing, wherein the distribution head housing is provided with a blowing chamber, a vacuum chamber I, a vacuum chamber II and a vacuum chamber III; the distribution head housing is also provided with two vacuum tube interfaces; the vacuum chamber II and the vacuum chamber III are communicated or a partition board is provided with air vents; the blowing chamber is internally provided with two blowing holes; the two vacuum tube interfaces are respectively communicated with the vacuum chamber I and the vacuum chamber III; the partition board is provided with a baffle; the baffle is fixed on the partition board through bolts. The distribution head of the rotary drum vacuum filter, disclosed by the invention, is especially suitable for the rotary drum vacuum filters which need to increase the filtering capacity due to thin filter residue.

Description

technical field [0001] The invention relates to drum vacuum filter equipment, in particular to a drum vacuum filter distribution head. Background technique [0002] Drum vacuum filter is a kind of continuous filter, the structure is similar to drum vacuum filter, and the operating principle is the same. It is a continuous filter with negative pressure as the driving force and the filter surface is on the surface of the cylindrical drum. This filter was originally used in soda making and mining industries, and later expanded to chemical, coal and sludge dehydration and other departments. [0003] Drum vacuum filter has a horizontal drum, the drum wall is perforated, and the drum surface is covered with support plate and filter cloth to form the filter surface. The space under the filter surface is divided into several separate fan-shaped filter chambers, and each filter chamber has a conduit to communicate with the distribution valve. Every time the drum rotates once, each...
