Embodiment 1
[0033] Fig. 1 is an embodiment of the present invention, which is used for liquid extraction of tuber plants. The main motor, reduction gear mechanism and barrel pair are fixed on the frame, the main motor is connected with the reduction gear mechanism through a belt transmission device, the two output shafts of the reduction gear mechanism are connected to the two combined screw pairs installed in the barrel pair Connected by a coupling, the combined screw pair extends into the barrel pair, and the screw root is sealed with a screw dynamic seal. The barrel outlet on the other side of the barrel pair is connected to the dehydration head, and the dehydration head controls the opening degree by adjusting the upper and lower positions of the damping block, thereby adjusting the pressure of the water-containing material in the head and the barrel.
[0034] In this example, the dehydration ports C, D, E, F, and G adopt a separate design, and the diameter of the filter hole is 3 mm....
Embodiment 2
[0042] Fig. 3 is Embodiment 2 of the present invention, which is used for dehydrating materials with high water content and high fluidity. The difference between embodiment 2 and embodiment 1 is that embodiment 2 does not need to set a crushing knife in the forced feeder part because it does not need to crush the material, so use such as Figure 4 The block shown in (c) blocks the threaded hole of the crushing knife. The gear pair of the gear pump is a pair of gears meshing with each other, the diameter of the gear is 300mm, and the input shaft of the driving wheel is connected with the gear pump motor through a coupling. The upper end of the gear pump is connected with the forced feeder, and the lower end is connected with the upper filter cartridge.
[0043] Upper filter cartridge Two detachable upper filter cartridge filter plates with a filter hole diameter of 3 mm and a replaceable filter screen attached to the filter plate. Feeding port B mainly plays the role of exhaus...

Abstract
The invention belongs to the field of material breaking and dehydrating processing, and discloses a twin screw breaking and dehydrating integrated processing equipment with a gear pump; the equipment can be used for integrated processing of material friction breaking, extruding and forming, cell wall breaking, and solid-liquid extraction. The equipment comprises a main motor, a transmission belt, a reducing gear mechanism, a first coupling, a cylinder pair, a combined twin screw pair, connecting screws, an upper filtering cylinder fluid collecting device, the gear pump, a gear pump gear pair, a secondary breaking cutter, a forcing feeding spiral, a primary breaking cutter, a forcing feeder cylinder, a second coupling, a forcing feeding motor, a machine head covering plate, an indexing adjustment screw, a damping block, a dehydrating machine head, an auxiliary feeding cylinder, an upper filtering cylinder, upper filtering cylinder filtering plates, a frame, an upper filtering cylinder indexing adjusting mechanism, a support seat, a gear pump motor, a third coupling and an automatic control system. The forcing feeder breaks material primarily. The upper filtering cylinder is provided with two upper filtering cylinder filtering plates. The cylinder pair is provided with two feeding ports and four dehydrating ports, and the dehydrating machine head is provided with one four dehydrating port. Material breaking and dehydrating processing can be implemented efficiently.
Description
technical field [0001] The invention relates to a twin-screw crushing and dehydration integrated processing equipment with a gear pump for crushing and dehydrating materials with high water content to reduce the water content. Background technique [0002] Squeeze dehydration is the operation of separating viscous solid-liquid mixture into solid and clarified liquid through filter cloth by mechanical compression. It is a highly dehydrating solid-liquid separation technology and is widely used in chemical industry, metallurgy, mining, energy, Dyes, pigments, inorganic chemicals, petrochemicals, biochemicals, pharmaceuticals, food, environmental protection and sewage treatment and other fields. [0003] At present, the commonly used extrusion dehydration devices can be divided into three types: cylinder / plate and frame filter press, belt filter press, continuous screw filter press and so on. [0004] Cartridge / plate and frame filter press is the simplest structure among commo...
