Description
Technical field
The utility model belongs to water-treatment technology field, particularly a kind of pressure filter.
Background technology
The tank body material of pressure filter is divided into stainless steel, carbon steel line with rubber and glass steel material.And tank body generally adopts glass steel material, cost performance is high.But due to the maloperation of operating personnel, easily cause fiberglass tank body to damage.In order to prevent fiberglass tank body from damaging, on fiberglass tank body, increase rupture disk, setting rupture disk pressure is at 0.4MPa.When filter reaches 0.4MPa due to people for maloperation, rupture disk breaks, and reaches the object of cover glass cylinder of steel body.But, because rupture disk is generally lucite material, withstand voltage not high, do not reach 0.4MPa just easily cracked, and cracked after need again more to renew rupture disk, need long-term explosion diaphragm for subsequent use.
Utility model content
The purpose of this utility model is to provide a kind of structure simple pressure filter, it is provided with control box and relief valve, when in tank body, pressure is greater than setting value, control relief valve by control box automatically to open, in reduction tank body, pressure is until setting value, make fiberglass tank body pressure remained steady, avoid damaging tank body.
The purpose of this utility model is realized by such technical scheme, it comprises delivery pump, the first valve, tank body and the second valve, described delivery pump is communicated in the tank body of top by the first valve, screen pack is horizontally arranged with in described tank body, the top of described tank body is provided with relief valve and pressure sensor, be connected with control box between described relief valve and pressure sensor, one end of described second valve is communicated in the tank body of bottom, and the other end of described second valve is connected with filtrate (liquid end.
The utility model operationally, control box arranges a steady pressure value, opens the first valve, close the second valve, and start delivery pump.Liquid to be filtered is pressed in tank body by delivery pump, and is full of tank body.Under the effect of the pressure, the solid impurity in filtrate is filtered net and retains, and forms filter cake on screen pack, and filtrate enters tank body lower part through screen pack.
After filtrate has been filtered, open the second valve, flow into filtrate (liquid end through the filtrate of filtering through the second valve.
Pressure sensor is used for the pressure size in perception tank body, generates pressure signal, and pressure signal is transferred to control box.The pressure signal received processes by control box, and by the force value that obtains after process compared with the force value of setting.When the force value obtained after processing is greater than the force value of setting, control opening of relief valve by control box.The pressure in tank body can be reduced after opening relief valve.
Along with the reduction of pressure in tank body, the pressure size of pressure sensor also in real-time perception tank body, and pressure signal is transferred to control box.When control box processes the pressure signal received, and when the force value obtained after process is less than the force value of setting, close relief valve.
Therefore, when the force value in tank body is greater than setting value, relief valve is opened; When force value light rain setting value in tank body, close relief valve.Circulation like this, makes the force value in tank body equal with setting value, avoids damaging tank body.
Further, described pressure filter also comprises Pressure gauge, and described Pressure gauge is connected with pressure sensor.
Further, described inner tank wall is provided with corrosion-inhibiting coating.
Further, described tank body is fiberglass tank body, and described screen pack is stainless steel filter screen.
Further, described first valve and the second valve are magnetic valve.
Owing to have employed technique scheme, it has the simple advantage of structure, it is provided with control box and relief valve, when in tank body, pressure is greater than setting value, control relief valve by control box automatically to open, reduce pressure in tank body and, until setting value, make fiberglass tank body pressure remained steady, avoid damaging tank body.

Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, the utility model comprises delivery pump 1, first valve 2, tank body 4 and the second valve 3, described delivery pump 1 is communicated in top tank body 4 by the first valve 2, screen pack 5 is horizontally arranged with in described tank body 4, the top of described tank body 4 is provided with relief valve 6 and pressure sensor 7, be connected with control box 8 between described relief valve 6 and pressure sensor 7, one end of described second valve 3 is communicated in bottom tank body 4, and the other end of described second valve 3 is connected with filtrate (liquid end.
The utility model operationally, control box 8 arranges a steady pressure value, opens the first valve 2, closes the second valve 3, and starts delivery pump 1.Liquid to be filtered is pressed in tank body 4 by delivery pump 1, and is full of tank body 4.Under the effect of the pressure, the solid impurity in filtrate is filtered net 5 and retains, and forms filter cake on screen pack 5, and filtrate enters tank body 4 bottom through screen pack 5.
After filtrate has been filtered, open the second valve 3, flow into filtrate (liquid end through the filtrate of filtering through the second valve 3.
Pressure sensor 7, for the pressure size in perception tank body 4, generates pressure signal, and pressure signal is transferred to control box 8.The pressure signal received processes by control box 8, and by the force value that obtains after process compared with the force value of setting.When the force value obtained after processing is greater than the force value of setting, control opening of relief valve 6 by control box 8.The pressure in tank body 4 can be reduced after opening relief valve 6.
Along with the reduction of pressure in tank body 4, the pressure size of pressure sensor 7 also in real-time perception tank body 4, and pressure signal is transferred to control box 8.When control box 8 processes the pressure signal received, and when the force value obtained after process is less than the force value of setting, close relief valve 6.
Therefore, when the force value in tank body 4 is greater than setting value, relief valve 6 is opened; When force value light rain setting value in tank body 4, close relief valve 6.Circulation like this, makes the force value in tank body 4 equal with setting value, avoids damaging tank body 4.
As shown in Figure 1, as specific embodiment, described pressure filter also comprises Pressure gauge 9, and described Pressure gauge 9 is connected with pressure sensor 7.Described Pressure gauge 9 shows the force value in tank body 4 in real time.When the force value in tank body 4 is greater than the setting value of control box 8, operating personnel can manual unlocking relief valve 6, and when the force value in tank body 4 is less than the setting value of control box 8, operating personnel can manual-lock relief valve 6.Circulation like this, makes the force value in tank body 4 equal with setting value, avoids damaging tank body 4.
As shown in Figure 1, as specific embodiment, described tank body 4 inwall is provided with corrosion-inhibiting coating.Corrosion-inhibiting coating can prevent some filtrate from entering into tank body 4 post-etching tank body 4 inwall, causes damage to tank body 4.
As shown in Figure 1, as detailed description of the invention, described tank body 4 is fiberglass tank body 4, and described screen pack 5 is stainless steel filter screen 5.
As shown in Figure 1, as detailed description of the invention, described first valve 2 and the second valve 3 are magnetic valve.
These are only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing the utility model description and accompanying drawing content to do; directly or indirectly be used in the technical field that other are relevant, all in like manner within scope of patent protection of the present utility model.
