It is easy to collect.When clearing up fragment, the capping of sewage pipe position need to be only dismantled, fragment is automatically fallen off.
Preferably, the collection pot bottom is provided with several secondary supports；Bracket (bottom plate with horizontal, the bottom plate
On be vertically arranged two vertical plates, two vertical plates are arranged in parallel, and two vertical plate upper portion side walls extend laterally, and elongated end end face is welded in collecting tank tank body
Lateral wall.This structure, support strength is big, and support is firm, makes collecting tank be not easy to vibrate under liquid flow impact, is less susceptible to shake,
The fragment of internal gathering is avoided to shake and influence collection efficiency.
Preferably, having backing layer on the inside of the tank body of the collecting tank, backing layer bottom is the recessed taper in middle part
Bottom.Convenient for debris sedimentation and collection.
Preferably, the collecting tank has the rack of polyfluortetraethylene plate welding fabrication；Rack has in cylinder-shaped
Strainer locating slot is arranged on bottom plate and support plate in the bottom plate of horizontal and the support plate for being vertically arranged between base portion peripheral；If having on rack
Dry screw hole, filter screen are fixed on rack by engineering plastics bolt.
Therefore, the present invention has the characteristics that structurally reasonable, easily fabricated, especially by isolation dividing technology by solid with
Liquid separates, and small in size, pollution discharge capability is stronger, and collecting filler can clear up in time, does not easily cause fluid flow to reduce, is not easy to block up
Plug, and it is simple, convenient when cleaning.Inlet tube uses elbow, has baffle effect, is easily isolated fragment, allows solid in liquid
Particle is determined automatically by the intermediate channel of filter screen, and automatic sedimentation is in collecting tank.

Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment: filtration device before pump of the present invention, as shown in attached drawing 1, attached drawing 2, attached drawing 3, attached drawing 4 comprising collecting tank
3, sewage pipe 4 is arranged in the middle part setting filter screen 5 of collecting tank 3, top setting inlet tube 1, side setting outlet 2, bottom, into
Mouthful pipe 1 is bend pipe, and the center line of both ends oral area is oblique or square crossing.3 side wall of collecting tank is provided with visor 7.3 bottom of collecting tank
It is provided with several secondary supports 6；The bracket 6 has the bottom plate of horizontal, is vertically arranged two vertical plates on bottom plate, and two vertical plates are arranged in parallel, and two is vertical
Plate upper portion side wall extends laterally, and elongated end end face is welded in 3 tank body lateral wall of collecting tank.
There is backing layer, backing layer bottom is the recessed conical bottom in middle part on the inside of the tank body of collecting tank 3.
Collecting tank 3 has the rack of polyfluortetraethylene plate welding fabrication；Rack is in cylinder-shaped, bottom plate with horizontal and perpendicular
The support plate in base portion peripheral is set, strainer locating slot is set on bottom plate and support plate；There is several screw holes, filtering on rack
Net 5 is fixed on rack by engineering plastics bolt.
As an alternative preferred version, there is 3 bottom of collecting tank fragment to consider frame 8；It includes branch that the fragment, which considers frame 8,
Support body 81, the upper and lower part setting setting through-hole 88 of supporter 81,81 bottom of supporter wraps 4 nozzle of sewage pipe, and passes through
Through-hole 88 is connected to 4 nozzle of sewage pipe；Setting may pass through the outer tube 83 that 5 middle part of filter screen is connected to inlet tube 1 on supporter 81,
Conical pipe 86 is arranged in 83 top inner wall of outer tube, and inner tube 85 is arranged in 86 bottom of conical pipe；Pipe 84 in being arranged on supporter 81, middle pipe 84
Supporter 81 is fixed in one end, the other end protrudes between outer tube 83 and inner tube 85, has between inserting end end and conical pipe 86
Annular gap；Filter screen set 87 is arranged in 85 bottom of inner tube, and filter screen set 87 is ring seal structure, both ends open, two open ends difference
Connect inner tube 85 and middle pipe 84；Outer tube 83 has several drainage holes 82.The acidic liquid accessed from inlet tube, into conical pipe
86, it flows downward in inner tube, then pipe flows up in passing through；In inner tube nozzle base, fragment settles under the effect of gravity, substantially
Improve the cleannes of acidic liquid.
Supporter 81 is the tube structure with cavity, and the diameter of cavity is greater than two through hole (88) diameter.It provides more
Fragment deposits collection space, and is conducive to reduce overall weight.
