Description
Technical field
The utility model relates to a kind of filter plant, is specifically related to a kind of vacuum filter that is used for titanium sponge vacuum distillation.
Background technology
Vacuum filter is a kind of filter plant that is applied in the titanium sponge vacuum distillation process.The effect of vacuum filter is that the solid dust impurity that will enter the distillation vacuum pipe in the middle of the titanium sponge vacuum distillation process is collected filtration, thereby prevents that solid dust impurity from entering the damage that vacuum equipment causes vacuum equipment.Existing vacuum filter belongs to simple inertial filter equipment.Filter is made up of cylindrical shell, air inlet, gas outlet, slag-drip opening, baffle plate etc.The gas that contains solid dust impurity directly enters in the filter cylinder by air inlet, the baffle plate that is arranged on the cylindrical shell centre separates air inlet and gas outlet, solid dust impurity in the gas collides with baffle plate, barrel in cylindrical shell, movement velocity reduces, and dust is subjected to the self gravitation effect to be deposited on the cylindrical shell bottom at last.This structure can be filtered the bigger solid dust impurity of particle diameter, however the less solid dust impurity of particle diameter can be taken away by air-flow, so will be subjected to very big influence for the less solid dust contaminant filter effect of particle diameter.It is often bigger that but the particle diameter of the solid dust impurity that the gas by vacuum filter contains distributes, and this just makes the filter efficiency of vacuum filter fall very lowly.After solid impurity enters follow-up vacuum equipment, cause that the pump greasy dirt dyes, equipment is stuck, cause the shutdown maintenance frequency of follow-up vacuum equipment to increase, service life of equipment reduces, and finally causes the rising of production cost.Angle from titanium sponge vacuum distillation technology, the requirement of vacuum filter should be, should filter out solid dust impurity, keep simultaneously certain conductance and gas handling capacity again, otherwise can cause vacuum pumping rate to descend even can't vacuumize, so vacuum filter must be realized solid dust contaminant filter ability and the balance of keeping certain gas admittance.Yet this point but is the defective that original vacuum filter exists.
The utility model content
In view of this, the purpose of this utility model is deficiency and the defective that exists at former vacuum filter, and a kind of vacuum filter that is used for titanium sponge vacuum distillation is provided, and it can effectively filter the solid dust impurity that contains in the retort gas.
Above-mentioned purpose realizes by following proposal:
A kind of vacuum filter that is used for the titanium sponge vacuum distillation process, it comprises: cylindrical shell, end socket, top cover, air inlet pipe, escape pipe and supporting leg, described end socket is welded on described cylindrical shell lower end, described top cover is fixed on described cylinder top, described air inlet pipe is welded on the described top cover, described escape pipe is welded on the sidewall of described cylindrical shell top, described supporting leg is fixedly mounted on the bottom of described vacuum filter, it is characterized in that, described vacuum filter also comprises central tube, one end of described central tube is connected the cylindrical shell top cover, and is communicated with described air inlet pipe; Have oil strain in the space that described end socket forms, the position in described cylindrical shell between described oil strain liquid level and described escape pipe is provided with filter screen, and described filter screen around described central tube until the described cylinder inboard wall of contact; Side at described end socket is provided with oil inlet pipe, is provided with drain line in the bottom of described end socket.
Vacuum filter according to above-mentioned is characterized in that, the thickness of described filter screen is 280～350mm.
Vacuum filter according to above-mentioned is characterized in that, is provided with manhole at the sidewall of described cylindrical shell.
Vacuum filter of the present utility model adopts oil strain and filter screen secondary filter that solid dust impurity is effectively filtered, thereby strict guarantee the normal operation of follow-up vacuum equipment, greatly reduce the vacuum equipment shutdown maintenance frequency, improved the service life of equipment, and then reduced production cost.
Description of drawings
Fig. 1 is a structure of filter schematic diagram of the present utility model.
The specific embodiment
Referring to Fig. 1, the vacuum filter that is used for the titanium sponge vacuum distillation process of the present utility model comprises: cylindrical shell 1, end socket 2, top cover 3, air inlet pipe 4, escape pipe 5 and supporting leg 6, end socket 2 is welded on cylindrical shell 1 lower end, top cover 3 is fixed on cylindrical shell 1 top, air inlet pipe 4 is welded on the top cover 3, escape pipe 5 is welded on the cylindrical shell 1 top sidewall, and supporting leg 6 fixed installations (for example by welding) are in the bottom of vacuum filter (that is end socket 2).And vacuum filter inside also comprises central tube 7, and an end of central tube 7 is connected on the top cover 3, and is communicated with air inlet pipe 4; Have oil strain 8 in the space that end socket 2 forms, the position cylindrical shell 1 between oil strain 8 liquid levels and escape pipe 4 is provided with filter screen 9, and filter screen 9 around central tube 7 until contacting cylindrical shell 1 inwall; Side at end socket 2 is provided with oil inlet pipe 10, is provided with drain line 11 in the bottom of end socket 2.
In order to guarantee the filter effect of filter screen, the thickness of filter screen 9 can be 280～350mm.For the ease of maintenance, be provided with manhole 12 at the sidewall of cylindrical shell 1.
During use, the gas that contains solid dust impurity enters central tube 7 by the air inlet pipe 4 that is positioned at the filter top end middle part, carry out mixed flow with central tube 7 terminal relative oil strain layers, adhesion by oil strain self adheres to the solid dust impurity in the gas get off then, and then be deposited on bottom the oil reservoir, the small amount of solid dust impurity that is not adhered to will carry out secondary filter through the filter screen 9 with certain porosity, finally finish the effective filtration to solid dust impurity.
