Description

Mechanical device for detecting leakage of diaphragm plate

Technical Field

The utility model relates to the technical field of plate-and-frame filter press equipment, in particular to a mechanical device for testing leakage of a diaphragm plate.

Background

The plate-and-frame filter press is a mechanical device which applies a certain pressure to a target by utilizing a special filter medium to dialyze liquid, and is a common solid-liquid separation device. The filter plate has the advantages of stable performance, convenient operation, safety, labor saving and the like. After the filter press is pressed and pressure-maintained, the filter pulp is forced to pass through a filter medium under the action of pressure, solid particles are intercepted on the medium, and liquid passes through the filter medium, so that the aim of separating the liquid from the solid is fulfilled.

Plate-and-frame filter presses are divided into two broad categories, including chamber-type plate-and-frame filter presses and membrane plate-and-frame filter presses. The important component of the diaphragm plate-and-frame filter press is a diaphragm plate, water or gas is introduced into the diaphragm plate to swell the diaphragm, materials in a filter plate cavity are squeezed, a liquid phase in the materials is extruded to pass through the filter cloth, and a solid phase is remained on the filter cloth.

The diaphragm plate and frame filter press carries out the secondary extrusion to the filter cake on van-type plate and frame filter press's basis, therefore the relative van-type plate and frame filter press mud cake dryness fraction of diaphragm plate and frame filter press is higher, and the filter effect is better. Due to the gas expansion speed, the safety is poor, and the diaphragm plate filled with water as a medium is basically adopted at present. However, once the diaphragm is broken, the pressing water enters, so that the water content is increased, and the working efficiency of the diaphragm plate-and-frame filter press is affected.

The tightness of the diaphragm plate is not controlled in the prior art, once the diaphragm plate is broken, the diaphragm plate can extrude a filter cake to cause a reaction, and the humidity of the mud cake is increased, so that invalid filtration is caused.

In order to ensure the sealing performance of the diaphragm plate, a set of leakage detection mechanical device needs to be designed on the diaphragm plate to ensure the sealing performance of the diaphragm plate.

Detailed Description

To facilitate an understanding of the present invention by those skilled in the art, specific embodiments thereof are described below with reference to the accompanying drawings.

In order to guarantee the leakproofness of diaphragm plate 80, set up a diaphragm plate leakage inspection mechanical device on every diaphragm plate 80, in case there is diaphragm plate 80 to leak and can judge fast and damage diaphragm plate 80 position, avoided equipment user to check by one, reduced personnel extravagant, improve maintenance efficiency.

As shown in fig. 1 to 3, the present invention provides a mechanical device for testing leakage of a diaphragm plate, including a first connection pipe 10 and a second connection pipe 20 communicated with the first connection pipe 10, wherein a detection assembly 30 is disposed between the first connection pipe 10 and the second connection pipe 20.

The detection assembly 30 comprises two fixing plates 310 and a transparent detection cavity 340 arranged between the two fixing plates 310, a floating ball 320 and a filter screen 330 arranged on the inner wall of the detection cavity 340 are arranged in the detection cavity 340, the first connecting pipe 10 is connected with a water inlet pipe port 50 arranged on the diaphragm plate 80, and the second connecting pipe 20 is connected with a water pump.

Specifically, the first connection pipe 10 is connected to the water inlet pipe port 50 of the diaphragm plate 80 through the connection fitting 40. The connection joint 40 is provided as a through joint. The size of the coupling adapter 40 is selected according to the outer diameter of the first connection pipe 10 and the inner diameter of the water inlet pipe port 50 of the diaphragm plate 80.

The inner pipes of the first and

second connection pipes

10 and 20 are formed in a spiral shape, and the spiral thread is preferably formed in a rectangular shape, so that water is in a spiral state when passing through the first and

second connection pipes

10 and 20, thereby driving the floating ball 320 to rotate, and thus determining whether the diaphragm plate 80 is leaked.

In order to prevent the floating ball 320 from being detached from the detection chamber 340, a filter 330 is fixed to the inner walls of both sides of the detection chamber 340. The filter 330 may also be fixed at the first connection pipe 10 near the side of the sensing chamber 340 and the second connection pipe 20 near the side of the sensing chamber 340, respectively.

The diaphragm plate 80 inlet conduit port 50 is generally located on the underside of the diaphragm plate 80. The inlet conduit port 50 is sized according to the size of the diaphragm plate 80. The diaphragm plate 80 leak testing mechanism is mounted to the diaphragm plate 80 at the inlet port 50 of the water pipe.

The floating ball 320 is a hollow plastic member, which can be in a floating state in water. The detection cavity 340 is made of transparent plastic, so that the state of the floating ball 320 can be observed conveniently.

The second connection pipe 20 is connected to the water pump through a water pipe 60, and the second connection pipe 20 and the water pipe 60 are sealed by a ferrule 70. The ferrule 70 is made of a material having good pressure resistance and sealing performance.

Operation of the diaphragm plate 80 leak testing mechanism:

when the diaphragm extruding device works, water is injected into the diaphragm plate 80 through the pipeline by the pressure pump, the water passes through the diaphragm plate 80 leakage inspection mechanical device when being injected into the diaphragm plate 80, the floating ball 320 rotates in the detection cavity 340 along with water flow, and when the extruding water is filled, the water flow does not flow any more, and the floating ball 320 is suspended on the water surface and is in a static state. Under normal operating condition, the float ball 320 only rotates when injecting water and releasing pressure, and is static under the pressure maintaining condition. In the pressure maintaining state, if the diaphragm plate 80 is broken, water of the leakage inspection mechanism of the diaphragm plate 80 flows, thereby rotating the floating ball 320. Whether the diaphragm plate 80 is damaged or not can be judged by observing the state of the floating ball 320. The difficulty in overhauling of equipment users is avoided, a mechanical device for detecting the leakage of the diaphragm plate is arranged on each diaphragm plate 80, the position of the diaphragm plate 80 can be rapidly judged and damaged once the leakage of the diaphragm plate 80 occurs, the equipment users are prevented from being checked one by one, the waste of personnel is reduced, and the maintenance efficiency is improved.
