Description

A filter water tank for a wet dust removal device

technical field

The utility model relates to the technical field of flue gas purification, in particular to a filter water tank used for a wet dust removal device.

Background technique

Wet dust removal device is a kind of purification equipment used to deal with trace dust and fine particles. It is mainly used to remove dust, acid mist, liquid droplets, aerosols, PM2.5 and other harmful substances in the gas. It has high dust removal efficiency and pressure. With the advantages of small loss, simple operation and low energy consumption, it is an ideal equipment for controlling atmospheric dust pollution.

The common wet dedusting device is like an empty tower. The spray device on the top of the empty tower sprays water downward from the top of the empty tower, and the dusty gas goes up in reverse, and the impurities in the dusty gas will combine with the water and fall down. In order to realize water recycling, the waste water at the bottom of the empty tower is often filtered through the filter in the filter water tank, and then returned to the spraying device at the top of the empty tower through the water pump and sprayed again.

After the filter water tank in the prior art is used for a long time, more impurities are often attached to the filter screen in the filter water tank and hinder the normal transportation of water, thereby affecting the dust removal of the wet dust removal device. For this reason, the operator needs to replace the filter screen in the water tank more frequently, which is time-consuming and laborious, and the process of changing the filter screen is also very troublesome.

Utility model content

The purpose of this utility model is to provide a filter water tank for a wet dust removal device, which can quickly and conveniently replace the filter screen in the water tank.

The above-mentioned utility model purpose of the utility model is achieved by the following technical solutions:

A filter water tank for a wet dust removal device, comprising a support frame, a box body installed on the support frame and provided with a water inlet and a water outlet, and a sewage outlet arranged at the lower end of the box body. The rotating shaft is connected with a circular rotating plate that rotates synchronously with the rotating shaft. During the rotation of the rotating plate, the water outlet is always covered, and the end of the rotating shaft away from the rotating plate passes through the outer wall of the box; A plurality of installation holes are opened, and a filter screen covering the water outlet is connected in the installation hole, and the plurality of filter screens will face the water outlet one by one during the process of rotating with the rotating plate; the box body is also equipped with a A rotating mechanism that drives the rotating shaft to rotate. The rotating mechanism includes a worm wheel that is fixedly sleeved on one end of the rotating shaft that passes through the outer wall of the box, a worm that is rotatably connected to the box and meshes with the worm wheel, and a motor for driving the worm to rotate.

By adopting the above technical scheme, the waste water enters the box through the water inlet, and as the volume of the waste water continues to rise, the waste water will pass through the filter and flow out of the box from the water outlet, and the impurities in the waste water will be filtered out by the filter and left behind. into the box. When there are more impurities attached to the filter, the operator starts the motor to drive the worm to rotate. Under the joint action of the worm and the worm, the shaft and the rotating plate rotate, and the filter will rotate with the rotating plate. The filter screen with more impurities can be replaced. In addition, the self-locking ability of the worm gear itself can effectively fix the positions of the rotating shaft and the rotating plate without other fixing mechanisms, avoiding the misalignment of the filter screen and the water outlet due to the rotation of the rotating plate.

By adopting the above technical scheme, the flaring setting at the notch of the card slot increases the area of the notch of the card slot, so that the card slot on the rotating plate can cooperate with the card block more smoothly, so that the operator can adjust the position of the rotating plate The installation is smoother, which improves the efficiency of the operator in installing the rotating plate.

The utility model is further configured as: the rotating plate is fixedly connected with a plurality of gripping parts which are convenient for the operator to move the rotating plate.

By adopting the above technical solution, the setting of the gripping portion provides a good force application site for the operator to move the rotating plate, so that the operator can move the rotating plate more conveniently and easily.

The utility model is further configured as follows: the box body is provided with an observation window for observing the internal conditions of the box body.

By adopting the above technical scheme, the operator can observe the situation inside the box very intuitively and clearly through the observation window, which is beneficial for the operator to replace the filter screen on the rotating plate in time, so that the filtration of wastewater can be kept at a relatively low level. Good level, and secondly, to make the alignment of the filter screen and the water outlet smoother.

The utility model is further configured as follows: the inner bottom wall of the box body is inclined downward toward the sewage outlet.

By adopting the above technical scheme, the inclined setting of the inner bottom wall has a collection and guiding effect on the impurities in the box, so that the impurities can fall into the sewage outlet at the first time, greatly reducing the residue of impurities in the box.

The utility model is further configured as follows: the water outlet is set at a position close to the upper part of the box body.

By adopting the above-mentioned technical scheme, firstly, the capacity of the box body for impurities is increased, and secondly, accumulated impurities are prevented from clogging the filter screen, thereby affecting the normal transportation of waste water.

In summary, the beneficial technical effects of the utility model are:

1. The setting of rotating plate, installation hole, filter screen and rotating mechanism greatly facilitates the operation of the operator to replace the filter screen;

2. The setting of the through hole, card slot, card block and abutment block facilitates the operator to clean the filter screen on the rotating plate in the future;

3. With the setting of the observation window, the operator can visually observe the condition of the filter screen inside the box, and replace the filter screen in time. In addition, it also makes the alignment of the filter screen and the water outlet more smooth.
