Abstract

The invention discloses a device for removing the float sludge in a reaction tank of water plant. The device can effectively remove float sludge in a reaction tank and has the advantages of low cost and convenient operation. The key points of the technical scheme are as follows: the front end and rear end of the first grid in the water inlet of the reaction tank are both provided with a funnel; the upper part of each funnel is in a rectangular shape, the lower part of each funnel is in a round shape; each funnel is connected to a lifting screw, a hand wheel is arranged on the lifting screw, the lower part of each funnel is provided with a pipeline and a valve; and the water outlet of the reaction tank is provided with a sludge discharge tank.

Description

Water factory's reaction tank mud scum removes device

Technical field

The present invention relates to the mud scum in water treatment field and remove device, specifically remove device about the mud scum in the reaction tank of waterworks.

Background technology

Due to flocculating effect that former water and Water purification medicament can produce after reacting in the integrated water production process of waterworks, if the cotton-shaped body produced is too much, will constantly be polymerized formation mud scum, due to distributing well, to fall head excessive in addition, water distribution is involved in too much air, producing bubble, add the generation of cotton-shaped body in water, cotton-shaped body is constantly polymerized formation mud scum. Due to the existence of mud scum, affect the normal operation of water treatment, and then the stable of effluent water quality can be affected again.

Current water factory uses the method with broken off by water flush mud scum, this kind of method compares traditional way, mainly utilize hydrant hydraulic pressure impacted by the mud scum on the water surface and break up so that it is precipitation, then by mud valve and suction mud driving, mud scum and the mud of precipitation are together drained into Pai Nigou. This kind of Measures compare is simple, but this kind of method has following shortcoming:

1. labor intensive power. It is generally required to 2 people, per tour needs to carry out repeatedly.

2., consume Water purification medicament more. Being reentered in water along with mud scum breaks up, in order to ensure water quality, the input amount improving Water purification medicament of having to during dosing, to improve coagulation effect.

3. affect effluent water quality. Mud scum is broken up to be entered in water, runs continuously owing to making aquatic product, and artificial flushing is that discontinuity carries out, and has part mud scum still can be flowed into next processing links, such as rectangular sedimentation tank etc., finally affects effluent water quality.

Summary of the invention

In order to solve the problem, the present invention is by the following technical solutions, at the forward and backward two ends of reaction tank water inlet place first lattice, a funnel is respectively installed, funnel top is rectangle, and funnel bottom is circular, and funnel is connected with lifting screw rod, screw rod is equipped with handwheel, in funnel bottom, pipeline, valve are installed, in reaction tank water outlet place, it are designed with mud drainage slot.

Described funnel upper width is equal with reaction tank first lattice, and funnel opening height is 20 35cm.

Described mud drainage slot height 5cm lower than reaction tank, length is equal with reaction tank width, and pipeline and electric auto-control valve are housed bottom mud drainage slot.

The invention has the beneficial effects as follows: the mud scum that can effectively remove in reaction tank, and cost is low.

Accompanying drawing explanation

Fig. 1 is the vertical view of the present invention;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is the B-B sectional view of Fig. 1.

Embodiment

Below in conjunction with accompanying drawing, the invention will be further described, water technology according to water plant design, former water just starts to add Water purification medicament before entering reaction tank, thus, namely the first lattice at reaction tank 1 start to occur mud scum in a large number, thus the first lattice at reaction tank will start to remove mud scum, but mud scum also can occur successively in several lattice below of reaction tank in the reaction process of reaction tank, so also needing to arrange mud drainage slot 3 in water outlet place of reaction tank, as seen from Figure 1 before reaction tank 1 left side first lattice and water inlet place, funnel device is respectively equipped with at rear two ends, funnel upper width is equal with reaction tank first lattice, funnel opening height is 20 35cm, mud drainage slot 3 is equipped with on the right of reaction tank.From Fig. 2, see that mud drainage slot 3 is lower than reaction tank 1, low 5cm in practice, mud drainage slot length is equal with reaction tank width, muddy water at mud drainage slot 3 is discharged from mudhole 9, and the pipeline of mudhole is equipped with electric auto-control valve 4, and the interval time that electric auto-control valve 4 is opened and opening time can be arranged by experience in advance according to mud scum amount, such as, the interval time opened is 24 hours, and each opening time is 5 minutes, and often opening once substantially can mud in emptying mud drainage slot 3 and water. The structure of reaction tank first lattice forward and backward two ends funnel is the same, Fig. 3 shows, funnel 2 is equipped with elevating screw pair 5, handwheel 6 is equipped with on secondary 5 tops of elevating screw, rotation hand wheel 6 can drive funnel 2 one lifting, the height location of funnel 2 in reaction tank 1 is that the water level according to reaction tank 1 determines, owing to the water consumption of user can change, so the water level in reaction tank 1 also can upper and lower fluctuate, in order to the mud scum on the water surface can be got rid of well, so the position of funnel 2 also to be followed water level to adjust. Owing to the position of funnel 2 needs upper and lower adjustment, so funnel 2 bottom water outlet dress is flexible pipe 8, then flexible pipe 8 is inserted in hard pipeline. In funnel both sides, the wall of reaction tank first lattice being fixed with guide rail 7, funnel both sides are stuck in guide rail 7, make funnel along the upper and lower motion of guide rail 7, can only can not produce drift.

Claims

1. water factory's reaction tank mud scum removes device, it is characterized in that: on the left and right both sides of reaction tank water inlet place first lattice, a funnel is respectively installed, funnel top is rectangle, funnel bottom is circular, funnel is connected with lifting screw rod, screw rod is equipped with handwheel, in funnel bottom, pipeline, valve is installed, be designed with mud drainage slot in reaction tank water outlet place.
