Sludge mixing device for manufacturing ceramsite

Abstract

The invention belongs to the technical field of sludge treatment and relates to a sludge mixing device for manufacturing ceramsite. The device comprises a pulverizer and a mixing chamber; one side of the pulverizer is provided with a dried sludge conveying pipe; the top end of the dried sludge conveying pipe is provided with a pulverizer feed port; the bottom end of the pulverizer is provided with a dried sludge discharge port; a dried sludge conveying belt is arranged at the bottom of the dried sludge discharging port and fixed through a fixing rod; a mixing chamber is installed on the right side of the dried sludge conveying belt; a dried sludge feeding port is formed in one side of the top of the mixing chamber; a humidified sludge feeding port is formed in the middle of the top of the mixing chamber; a motor is arranged on the left side of the mixing chamber; the motor is fixed by a bearing base; a rotating shaft is horizontally arranged in the mixing chamber; one end of the rotating shaft is connected with the motor; the surface of the rotating shaft is sleeved with a propelling paddle and a stirring rod; the other end of the rotating shaft is fixed to an inner ring of a bearing. With the sludge mixing device adopted, the mixed stirring of dried sludge and wet sludge can be realized, and automatic degree of the devise is high.

Description

technical field

[0001] The invention relates to the technical field of sludge treatment, in particular to a sludge mixing device for producing ceramsite. Background technique

[0002] Sludge mixing technology is currently widely used in the field of sludge treatment. At present, the commonly used sludge mixing equipment includes drum type, screw type, centrifugal type, membrane type, paddle type, etc., for wet sludge with a moisture content of more than 90%. When it is carried out directly, there will be a viscous zone in the sludge, and the cohesive force and adhesion of the sludge are relatively large, resulting in a decrease in the drying rate of the sludge and an increase in the stirring power, which greatly increases the workload of the dryer and also causes transmission. The heat will deteriorate and pose a safety hazard. Mixing the dried sludge with the wet sludge with high moisture content reduces the moisture content of the sludge, improves the viscosity characte...
