Description
Technical field
The invention belongs to filters pressing cylinders used in technical field of sludge treatment more particularly to a kind of sludge filter press.
Background technique
Filter press is the equipment for carrying out deep dehydration to sludge using filter-pressing process, after primary sludge is dehydrated by filter press
The lower mud cake of moisture content can be formed.Filter press type common at present has: common plate and frame filter press, box plate compression
Machine, diaphragm type plate and frame filter press and high pressure vertical filter press.Filter press mainly includes rack, hydraulic cylinder, filters pressing cylinder, filter plates
Part and pressing plate, the press filtration unit of filters pressing cylinder, pressing plate and filter plate assembly composition filter press, are provided with filter cloth in filters pressing cylinder bottom portion, press
Plate is set in filters pressing cylinder after being connected with filter plate assembly.Pressing plate can be along the axis side of hydraulic cylinder piston rod under the driving of hydraulic cylinder
To movement, to carry out filters pressing to the sludge in filters pressing cylinder.Filters pressing cylinder is a hollow cylinder body, and existing filter press is generally adopted
With center into the mode of mud, sludge is sent into filters pressing cylinder via the mud channel that enters for passing through filter plate assembly and pressing plate, this into mud side
Formula is slow and uneven into mud speed, while in pressure-filtering process, the pressure that the sludge of center is subject in filters pressing cylinder is non-constant,
It is easy to appear decline of pressure, it is not up to standard so as to cause the moisture content after the sludge press filtration of center.
Summary of the invention
The purpose of the present invention is to provide one kind into mud uniformly, into the fireballing sludge press filtration cylinder of mud.

Specific embodiment
Present invention will now be described in detail with reference to the accompanying drawings., when describing the embodiments of the present invention, for purposes of illustration only, indicating
The attached drawing of device architecture can disobey general proportion and do partial enlargement, and the schematic diagram is example, should not limit herein
The scope of protection of the invention.It should be noted that attached drawing uses simplified form and uses non-accurate ratio, only to side
Just, the purpose of the embodiment of the present invention is clearly aided in illustrating.
As depicted in figs. 1 and 2, the filters pressing cylinder 1 of the present embodiment is a circular hollow cavity, on the casing wall of filters pressing cylinder 1
It is machined with circumferentially spaced mud inlet 1a, it is preferred that the setting quantity of mud inlet 1a is even number, and circumferentially uniformly right
Title is spaced apart.Sludge can be sent into filters pressing cylinder 1 through the mud inlet 1a on casing wall from the side of filters pressing cylinder 1.Using side into mud
Mode, sludge can be made uniformly to send to filters pressing cylinder 1, multiple mud inlets can be improved into mud into mud speed simultaneously, but also can
To avoid center into existing for mud mode filters pressing cylinder center sludge because stress it is non-constant present in the pressure-filtering process
The problem of decline of pressure.Filters pressing cylinder 1 can be used the materials such as cast iron, stainless steel, aluminium alloy, steel alloy and be made.
Casing wall is radially protruded from it is further preferred that being provided on the lateral surface of 1 top casing wall of filters pressing cylinder
Interconnecting piece 1-1, interconnecting piece 1-1 form the flange of annular on casing wall.It is machined on interconnecting piece 1-1 circumferentially spaced solid
Determine through-hole 1-1a, the axis of fixed hole 1-1a is parallel with the axis of filters pressing cylinder 1.Fixed hole 1-1a is used to match with bolt
It closes, filters pressing cylinder 1 and the press plate connection board above filters pressing cylinder 1 is fixed together.Still more preferably, in filters pressing cylinder 1
The bottom of casing wall is machined with seal groove (not labeled), and gasket 3 is provided in seal groove, makes filters pressing cylinder 1 can by gasket 3
To be in close contact with the sealing being installed together with 1 bottom of filters pressing cylinder, good sealing is formed.The seal groove edge of the present embodiment
1 casing wall bottom of filters pressing cylinder is extended continuously, and is an annular groove.
