Embodiment 1

[0029] A nitrate slurry thickener, comprising a cylinder, the cylinder includes a cylinder part at the top and a cone part at the bottom, the top wall of the cylinder part is provided with a feed inlet, and the bottom of the cone part is The wall is provided with a discharge port, the feed port is connected with a feed pipe, the discharge port is connected with a discharge pipe, an electric control valve is installed on the feed pipe, and an electronic meter is installed in the discharge pipe. The heavy flow device, the anti-blocking device is installed in the cone part above the discharge port.

[0030] Through this setting, the nitric acid slurry enters the cylinder from the feed pipe for sedimentation and thickening, and the thickened nitric slurry is discharged from the discharge pipe. An electric control valve is installed on the feed pipe to accurately control the feeding speed of the nip slurry. An electronic weighing flow device is installed in the discharge pipe to fa...

Embodiment 2

[0032] On the basis of Embodiment 1, the anti-blocking device includes a rotating shaft arranged radially along the cylinder, a rotating roller is set on the rotating shaft, and several fins are installed on the rotating roller along the circumference of the rotating roller. A driving motor for driving the rotating shaft to rotate is installed outside the body. Through this setting, the drive motor drives the rotating shaft to rotate, and the rotating roller installed on the rotating shaft rotates accordingly, so that the fins can stir the nitrogen slurry above the outlet, preventing the nitrogen slurry from being blocked at the outlet and affecting the nitrogen slurry. Normal discharge.

Embodiment 3

[0034]On the basis of the above-mentioned embodiments, an annular scraper is installed along the inner wall of the cylindrical part, a connecting frame is installed on the inner side of the annular scraper, and an electric telescopic is installed outside the top wall of the cylindrical part. The output end of the electric telescopic rod passes through the top wall of the cylinder part and is connected with the connecting frame. Through this setting, the nitrate slurry attached to the inner wall of the column can be cleaned, preventing the nitrate slurry from accumulating on the inner wall, affecting the settling speed of the nitrate slurry, and improving the thickening efficiency of the nitrate slurry.

Abstract

The invention discloses a nitre slurry thickener, belongs to the technical field of anhydrous sodium sulphate production equipment, aims to provide a nitre slurry thickener, and solves the problems that an existing nitre slurry thickener is low in automation degree and a discharge port is easy to block. The nitre slurry thickener comprises a barrel body, the barrel body comprises a column body part located on the upper portion and a cone body part located on the lower portion, a feeding port is formed in the top wall of the column body part, a discharging port is formed in the bottom wall of the cone body part, the feeding port communicates with a feeding pipe, the discharging port communicates with a discharging pipe, and an electric control valve is installed on the feeding pipe; an electronic weighing flow meter is installed in the discharging pipe, and an anti-blocking device is installed at the position, located above the discharging port, in the cone part. The invention is suitable for the nitrate slurry thickener.

Description

technical field [0001] The invention belongs to the technical field of sodium sulfate production equipment, and in particular relates to a nip slurry thickener. Background technique [0002] Anhydrous sodium sulfate, also known as Yuanming powder, is widely used in industry. Nitrate is one of the important raw materials in the production process of sodium sulfate. The production process of sodium sulfate needs to involve the thickening of the nitric acid slurry. The usual method is to introduce the nitric acid slurry into the thickener for gravity settlement, and then add the thickened slurry to the thickener. The thickened nitric slurry is discharged and enters the subsequent process. However, the existing nitrate thickener has a low degree of automation, cannot accurately control the feeding of materials, and cannot accurately measure the discharge of materials. At the same time, the nitrate slurry at the discharge port is also prone to blockage, which will seriously affe...
