Description

A continuous chemical settling tank

technical field

The utility model relates to a chemical equipment, in particular to a continuous chemical settling tank.

Background technique

In the field of chemical industry, settling tanks are used to separate the solid particles in the feed liquid from the liquid, but the existing settling tanks are difficult to achieve continuous work. To achieve continuous work, the most important thing is to realize the continuous discharge of the supernatant liquid and bottom settlement of the settling tank. Solids; the solids discharge device of the general settling tank is likely to cause lifting problems due to the different viscosity of the solids, making the solids discharge unsmooth; at the same time, the discharge of the overflow clear liquid may form scars because the clear liquid contains a small amount of solid particles, Finally, the settlement tank cannot work continuously.

Utility model content

The purpose of this utility model is to provide a continuous chemical industry settling tank to solve the problems raised in the background technology above.

In order to achieve the above object, the utility model provides the following technical solutions:

A continuous chemical settling tank, including a tank body and a collection chamber; a feed pipe is installed in the middle of one side of the tank body; a second check valve is installed on the feed pipe; the upper part of the other side of the tank body is equipped with Overflow pipe; the other end of the overflow pipe is connected to the overflow tube; the bottom of the overflow tube is connected to the feed pipe through the delivery pipe; the top of the tank is equipped with a cover plate; the center of the cover plate is equipped with a hollow shaft The top of the hollow shaft is equipped with a rotary joint; the other end of the rotary joint is connected with the discharge pipe; the suction pump is installed on the discharge pipe; the upper part of the hollow shaft is connected with the first motor through a transmission belt; the middle position of the hollow shaft is set There is a suction port; the bottom of the hollow shaft is equipped with a scraper; the bottom of the tank is provided with a second discharge port; the second discharge port is connected to the collection chamber; one side of the collection chamber is equipped with an upward spiral blade; The top of the spiral blade is connected with the second motor; the first discharge port is arranged under the top of the spiral blade.

As a further solution of the utility model: on the conveying pipeline, a cut-off valve is installed at one end near the overflow cylinder; a first check valve is installed at the end near the feed pipe; between the cut-off valve and the first check valve A gear pump is installed between them.

As a further solution of the utility model: the level of the suction port is 10 cm lower than the level of the overflow pipe.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model has the advantages of simple structure, convenient operation, continuous sedimentation, and uninterrupted solid-liquid separation; through the action of rotation and centrifugation, the impurities that are not easy to precipitate gather on the inner wall of the tank; the suction is effected by setting a suction port on the hollow shaft. The content of solid particles in the liquid is reduced; the sediment at the bottom is scraped into the collection chamber through the bottom scraper, and then discharged through the screw conveying device; the liquid content in the sediment is effectively reduced.
