Problems solved by technology

[0002] Small sewage treatment equipment and water treatment technology research laboratories often use plate and frame filter press or stacked screw dewatering machine for sludge dewatering, which has problems such as large occupied area, low dehydration efficiency, high labor intensity and troublesome operation and maintenance, especially in sludge When the quantity is small, it is difficult to select the equipment and it is inconvenient to use
[0003] The disadvantages of the plate and frame filter press are that the feed port of the filter frame is easy to block, the filter cake is not easy to take out, and cannot be operated continuously. The moisture content of the mud is greater than 60%
The screw stacked sludge dewatering machine is noisy, and the moisture content of the sludge is higher than that of the plate and frame machine. The equipment is worn out, and sometimes impurities in the sludge wrap the electrodes, resulting in abnormal liquid level protection.
[0004] Existing small (or micro) sludge dewatering machines use vacuum suction filtration, which has problems such as low dehydration efficiency, easy blockage of filter bags, high moisture content of sludge, and high energy consumption of supporting equipment, which limits the popularization and use

Embodiment 1

[0038] Such as Figure 1-8 A fully automatic small sludge dehydration dryer shown, including:

[0039] Cylinder assembly 1, which is installed on the base 4, includes a top cover 102 installed on the top of a stainless steel sleeve 101, a top cover flange 103 is provided on the bottom periphery of the top cover 102, and a sleeve is provided on the top periphery of the sleeve 101 The flange 104, the top cover flange 103 and the sleeve flange 104 are fixedly connected by eyebolts 105, and an O-ring is arranged between the top cover flange 103 and the sleeve flange 104, and the top cover 102 is provided with There are a plurality of internal threaded ports 107, and the internal threaded ports 107 are connected with a pressure gauge 108, an exhaust valve 109, a gas-liquid separation valve 110, a temperature sensor 111, and a mud inlet pipe 112, and the mud inlet pipe 112 is connected with a high-pressure sludge pump 113 , the mud inlet pipe 112 is provided with a check valve 114 ...

Embodiment 2

[0052] A fully automatic small sludge dewatering dryer dehydration method, comprising the following steps:

[0053] Step 1) Open the manual valve 115, control the touch screen 601 on the electric control box 6, open the solenoid valve 117, and pump the sludge into the filter bag 202 through the high-pressure sludge pump 113, and the filter bag 202 separates the solid from the liquid under pressure ;

[0054] Step 2) By observing the pressure gauge 108, when the reading of the pressure gauge 108 reaches 0.4Mpa (adjustable), control the touch screen 601 on the electric control box 6, close the solenoid valve 117, and turn on the drive motor 301 in the drive assembly 3 to drive the first A permanent magnet 303 starts to rotate, and under the action of magnetism, it drives the second permanent magnet 306 to rotate, so that the stirring shaft 302 rotates. At the same time, the spiral scraper 307 installed on the stirring shaft 302 rotates, and the filter bag is moved by the spiral ...
