Description

A kind of expansion pipe

Technical field

A kind of expansion pipe of the present utility model relates to a kind of unpowered water-freeing arrangement of advective separation of oil settling tank, is the expansion pipe in the unpowered water-freeing arrangement specifically.

Background technology

Existing industrial sewage is processed the advective separation of oil settling tank draining that relates to coagulation in the treatment system and is all adopted the submersible pump draining, because power source expends large use cost height, the maintenance cost of submersible pump is also high.What submersible pump was got rid of is the water of advective separation of oil settling tank water-supplying chamber bottom, because submersible pump is the inhaling type draining, the dirt that is deposited in the bottom is sucked be discharged in the next stage treatment tank easily, load that can corresponding increase next stage treatment facility.

Summary of the invention

The defective that exists in order to overcome above-mentioned prior art, the purpose of this utility model are to provide a kind of expansion pipe in the double track automatic bailer in a kind of sewage disposal advective separation of oil settling tank.

In order to address the above problem, the technical scheme of employing is to comprise upper limit device 1, line position switch 2, floating drum 3, cloth weir board 4, drain box 5, slideway sleeve barrel 6, expansion pipe 7, header 8, motorized valve 9, bearing 10, lower retainer 11, guide slide 12, settling tank pool wall 13, drain box bracing or strutting arrangement 14, floating drum back up pad 15; It is characterized in that: there is symmetrical floating drum 3 both sides, drain box 5 front and back; Be welded with floating drum back up pad 15 on the drain box 5, drain box 5 upper limbs are cloth weir board 4, drain box 5 bottoms are connected with at least 1 expansion pipe 7, expansion pipe 7 connects header 8, header 8 is positioned at the below of drain box and is positioned at the bottom of advective separation of oil settling tank, header 8 passes settling tank pool wall 13, and header 8 is equipped with motorized valve 9 at the pipeline in the precipitation pool wall outside; Drain box bracing or strutting arrangement 14 is being welded respectively in drain box 5 left and right sides, be welded with slideway sleeve barrel 6 on the drain box bracing or strutting arrangement 14, slideway sleeve barrel 6 is enclosed within on the guide slide 12, guide slide 12 perpendicular to the ground being fixed on the bearing 10, and bearing 10 is fixed at the bottom of the settling tank pond; Floating drum 3 connects floating drum back up pad 15 1 ends, and floating drum supporting plate 15 the other ends are welded on the front and back plate washer of drain box 5.

Described double track automatic bailer guide slide 12 be 2 and center point-blank.

Slideway sleeve barrel 6 in the described double track automatic bailer be 2 and center point-blank.

Bearing 10 in the described double track automatic bailer be 2 and center point-blank.

Described settling tank double track automatic bailer is made of stainless material.

For preventing that expansion pipe is disconnected by the pulling of the buoyancy of floating drum, a kind of expansion pipe of the present utility model adopts following technical scheme.

A kind of expansion pipe comprises expansion pipe a7-1, expansion pipe b7-2, and bolt 7-3, gland 7-4, o RunddichtringO 7-5, tight fixed bolt 7-6, header take over 8-1 and it is characterized in that expansion pipe b7-2 exterior ring cap has the expansion pipe a7-1 of o RunddichtringO 7-5 and overcoat to closely cooperate; (for preventing that expansion pipe a7-1 is broken away from header by the pulling of the buoyancy of floating drum and takes over 8-1), expansion pipe a7-1 takes over 8-1 with header and is connected by the 7-6 tight fixed bolt, and expansion pipe a7-1 and header are taken over 8-1 o RunddichtringO 7-5 sealing; (being broken away from expansion pipe a7-1 by the pulling of the come-up buoyancy of floating drum for preventing expansion pipe b7-2) expansion pipe b7-2 overcoat has o RunddichtringO 7-5.

Beneficial effect

Facility investment, the operation expense of the unpowered energy consumption of double track automatic bailer, saving submersible pump are low; Need not safeguard after disposable the adjusting, almost without maintenance cost; And because the water of discharging is the clear liquid of settling tank upper surface all the time, its effluent quality is better than the water that submersible pump is discharged, and then has alleviated the load of next stage treatment facility.

Adopt expansion pipe of the present utility model, can prevent effectively that each joint in the expansion pipe 7 is broken away from by the pulling of the buoyancy of floating drum.

Description of drawings

The present invention is described further below in conjunction with drawings and Examples:

Fig. 1 double track automatic bailer front view;

Fig. 2 double track automatic bailer vertical view;

The I partial enlarged drawing of Fig. 3 expansion pipe

The II partial enlarged drawing of Fig. 4 expansion pipe

Among the figure: 1 upper limit device, 2 line position switches, 3 floating drums, 4 cloth weir boards, 5 drain boxs, 6 slideway sleeve barrels, 7 expansion pipes, 8 headers, 9 motorized valves, 10 bearings, 11 lower retainer, 12 guide slides, 13 settling tanks, 14 drain box bracing or strutting arrangements, 15 floating drum bracing or strutting arrangements; 7-1 expansion pipe a, 7-2 expansion pipe b, the 7-3 bolt, the 7-4 gland, the 7-5o RunddichtringO, the 7-6 tight fixed bolt, the 8-1 header is taken over.

Embodiment

Embodiment 1

The double track automatic bailer comprises upper limit device 1 as shown in Figure 1 and Figure 2, line position switch 2, floating drum 3, cloth weir board 4, drain box 5, slideway sleeve barrel 6, expansion pipe 7, header 8, motorized valve 9, bearing 10, lower retainer 11, guide slide 12, settling tank pool wall 13, drain box bracing or strutting arrangement 14, floating drum back up pad 15; It is characterized in that: there is symmetrical floating drum 3 both sides, drain box 5 front and back; Be welded with floating drum back up pad 15 on the drain box 5, drain box 5 upper limbs are cloth weir board 4, drain box 5 bottoms are connected with at least 1 expansion pipe 7, expansion pipe 7 connects header 8, header 8 is positioned at the below of drain box and is positioned at the bottom of advective separation of oil settling tank, header 8 passes settling tank pool wall 13, and header 8 is equipped with motorized valve 9 at the pipeline in the precipitation pool wall outside; Drain box bracing or strutting arrangement 14 is being welded respectively in drain box 5 left and right sides, be welded with slideway sleeve barrel 6 on the drain box bracing or strutting arrangement 14, slideway sleeve barrel 6 is enclosed within on the guide slide 12, guide slide 12 perpendicular to the ground being fixed on the bearing 10, and bearing 10 is fixed at the bottom of the settling tank pond; Floating drum 3 connects floating drum back up pad 15 1 ends, and floating drum supporting plate 15 the other ends are welded on the front and back plate washer of drain box 5.

Its principle of work is as follows: in the drainage procedure, along with the liquid level in the settling tank outlet sump constantly descends, drain box 5 also descends thereupon, until lower retainer 11 rear shake-up line position switches 2 cut out motorized valve 9, finishes draining.After sewage progressed into settling tank, the settling tank liquid level rose, and drain box 5 and then rises at once bit switch 2 arrival upper limit devices 1 of regulation liquid level together, waits for next time draining instruction, opens motorized valve 9, realizes again draining.The upper limit device is set, also can be used for connecting upper computer and realize the warning of liquid level superelevation, and liquid level falls in draining.

This device can all adopt stainless material to make when making, and the assurance effluent characteristics increases the service life.
