[0003] The purpose of this utility model is to provide a screw press wastewater treatment device to solve the technical problem of not being able to adjust the sludge-water separation effect.

[0004] To achieve the above objectives, the specific technical solution of this utility model for a stacked screw press wastewater treatment device is as follows:

[0005] A screw press type sewage treatment device includes a water tank, a water tank end cover, a connecting pipe, a treatment chamber, a pressing sleeve, an actuator motor, a drive sprocket, a connecting chain, a driven sprocket, a threaded rotating sleeve, an adjusting slide rod, a central rotating shaft, a spiral blade, a connecting bracket, a push plate, a push plate spring, a rectangular slider, and a rectangular slide groove. The water tank end cover is fixedly installed on the water tank, and the end cover is fixedly installed on one end of the connecting pipe. The other end of the connecting pipe is fixedly installed on the treatment chamber. The pressing sleeve is fixedly installed and connected to the treatment chamber. An actuator motor is installed on the pressing sleeve, and the output shaft of the actuator motor is installed on the central rotating shaft. A spiral blade is fixedly installed on the central rotating shaft. One end of the central rotating shaft is rotatably installed on the pressing sleeve, and the other end is rotatably installed on the connecting bracket. The connecting bracket is fixedly installed on the treatment chamber. A filter assembly is installed inside the water tank.

[0006] Furthermore, the filter assembly includes a first filter plate, a first filter plate with filter holes, a second filter plate, a second filter plate with filter holes, an outlet cap, and a slope. The first filter plate is slidably installed inside the water tank. The first filter plate has a first filter plate with filter holes, and there are multiple first filter plates. The second filter plate is slidably installed on the water tank. The second filter plate has a second filter plate with filter holes, and there are multiple second filter plates. An outlet cap for draining liquid is installed on the water tank. A slope for facilitating the discharge of wastewater is provided inside the water tank.

[0007] Furthermore, multiple slide plate filter holes are arranged in a linear array along the filter slide plate, and multiple slide plate filter holes are arranged in a linear array along the filter slide plate.

[0008] Furthermore, a drive sprocket is rotatably mounted on the extrusion sleeve, a threaded rotating sleeve is rotatably mounted on the extrusion sleeve, a driven sprocket is fixedly mounted on the threaded rotating sleeve, a connecting chain is installed between the driven sprocket and the drive sprocket, an adjusting slide rod is threadedly mounted on the threaded rotating sleeve, a rectangular slide groove is opened on the adjusting slide rod, a rectangular slider is fixedly mounted on the extrusion sleeve, the rectangular slider slides in contact with the rectangular slide groove, a push plate is slidably mounted on the middle rotating shaft, and a push plate spring is installed between the push plate and the adjusting slide rod.

[0009] Furthermore, a spring limiting post A is installed on the push plate, a spring limiting post B is installed on the adjusting slide rod, and the push plate spring is disposed between the spring limiting post A and the spring limiting post B.

[0010] Furthermore, the processing box has a cone-shaped structure.

[0012] Furthermore, a mud discharge pipe is fixedly installed on the extrusion sleeve.

[0013] The advantages of this utility model are:

[0014] 1. Wastewater to be treated is introduced into the treatment tank through the collection sleeve, and the actuator motor is started. The actuator motor drives the central shaft and the spiral blade to rotate simultaneously. Through the spiral action of the spiral blade, the sludge in the wastewater accumulates on the push plate. Under the action of the push plate spring, the sludge is squeezed to achieve mud-water separation. The wastewater is then collected into the water tank through the connecting pipe. As sludge accumulates at the push plate position, under the action of the spiral blade, the push plate overcomes the resistance of the push plate spring and discharges the sludge through the sludge discharge pipe.

[0015] 2. To adjust the mud-water separation effect, the driving sprocket is rotated relative to the driven sprocket via a connecting chain. The driven sprocket drives the threaded rotating sleeve to rotate. Through the threaded action between the threaded rotating sleeve and the adjusting slide rod, the adjusting slide rod and the rectangular slider slide relative to each other, causing the distance between the push plate and the adjusting slide rod to change. This adjusts the pre-compression of the push plate spring, thus changing the resistance pre-applied by the push plate spring on the push plate. Within a certain range, the greater the resistance, the better the mud-water separation effect. Attached Figure Description

The water tank 1 is fixedly mounted with the water tank end cover 2, which is fixedly mounted at one end of the connecting pipe 3. The other end of the connecting pipe 3 is fixedly mounted on the treatment tank body 4. The pressing sleeve 6 is fixedly mounted on and connected to the treatment tank body 4. The actuator motor 8 is mounted on the pressing sleeve 6. The output shaft of the actuator motor 8 is mounted on the middle rotating shaft 14. The spiral blade 15 is fixedly mounted on the middle rotating shaft 14. One end of the shaft 14 is rotatably mounted on the extrusion sleeve 6, and the other end of the middle shaft 14 is rotatably mounted on the connecting bracket 16. The connecting bracket 16 is fixedly mounted on the treatment tank 4. With this configuration, the sewage to be treated is poured into the treatment tank 4 through the collection sleeve 5, and the actuator motor 8 is started. The actuator motor 8 drives the middle shaft 14 and the spiral blade 15 to rotate simultaneously. Through the spiral action of the spiral blade 15, the sludge in the sewage accumulates on the push plate 17. Under the action of the push plate spring 18, the sludge is squeezed to achieve mud-water separation, so that the sewage is collected into the water tank 1 through the connecting pipe 3. As the sludge accumulates at the position of the push plate 17, and under the action of the spiral blade 15, the push plate 17 overcomes the resistance of the push plate spring 18 and discharges the sludge through the sludge discharge pipe 7.

[0028] The filter assembly includes a filter slide plate 21, a slide plate filter hole 22, a filter slide plate 23, a slide plate filter hole 24, an outlet cap 25, and an inclined surface 26. The filter slide plate 21 is slidably installed inside the water tank 1. The filter slide plate 21 has multiple slide plate filter holes 22. The filter slide plate 23 is slidably installed on the water tank 1. The filter slide plate 23 has multiple slide plate filter holes 24. The outlet cap 25 for draining liquid is installed on the water tank 1. The inclined surface 26 inside the water tank 1 is provided to facilitate the discharge of sewage.

To adjust the mud-water separation effect, the driving sprocket 9 is rotated relative to the driven sprocket 11 via the connecting chain 10. The driven sprocket 11 drives the threaded rotating sleeve 12 to rotate. Through the threaded action between the threaded rotating sleeve 12 and the adjusting slide rod 13, the adjusting slide rod 13 slides relative to the rectangular slider 19, causing the distance between the push plate 17 and the adjusting slide rod 13 to change. This adjusts the pre-compression of the push plate spring 18, changing the resistance that the push plate spring 18 pre-applies to the push plate 17. Within a certain range, the greater the resistance, the better the mud-water separation effect.
