Plastic particle storage tank

Abstract

The invention discloses a plastic particle storage tank. The plastic particle storage tank comprises a tank body, and a cleaning mechanism arranged on the tank body; the tank body is provided with a feed port and a discharge port; gate valves are arranged at the feed port and the discharge port; and each gate valve comprises a valve base, a first gate, a second gate, a first cylinder and a second cylinder, and the opposite ends of the first gate and the second gate are provided with cutting edges. The plastic particle storage tank has the following beneficial effects: each gate valve uses two cylinders for respectively driving the corresponding first gate and the corresponding second gate to move towards the same direction or move towards different directions to realize opening or closing of a material hole, so that the opening and closing speed of the material holes is greatly accelerated, and the feeding quantity and the discharge quantity precision of the tank body is higher; and meanwhile, as the cutting edges are arranged at the opposite ends of each first gate and the corresponding second gate, after the two cutting edges abut against each other, materials clamped between each first gate and the corresponding second gate can be cut off, and the materials are prevented from being stuck in the gate valves to influence the closing effect of the gate valves.

Description

technical field [0001] The invention relates to a plastic industrial basic equipment, in particular to a plastic particle storage tank. Background technique [0002] At present, in the production process of the plastics industry, the extruded material strips extruded by the extruder are cooled and dried, pelletized and screened, and then the pellets are sent to the storage tank through the feeder. The upper end of the storage tank is provided with a material inlet, and the lower end is provided with a material outlet. Both the inlet and the outlet are equipped with flapper valves. The opening and closing of the flapper valves control the feeding and discharging. The existing There is only one gate in the gate valve, and the gate moves from one side of the material hole to the other to realize the opening and closing of the material hole, but when the gate in this kind of gate valve is closed, it is easy to dislodge plastic particles It is clamped between the gate and the ma...

Problems solved by technology

The upper end of the storage tank is provided with a material inlet, and the lower end is provided with a material outlet. Both the inlet and the outlet are equipped with flapper valves. The opening and closing of the flapper valves control the feeding and discharging. The existing There is only one gate in the gate valve, and the gate moves from one side of the material hole to the other to realize the opening and closing of the material hole, but when the gate in this kind of gate valve is closed, it is easy to dislodge plastic particles It is clamped between the gate and the material hole, which affects the sealing effect of the slide valve. At the same time, the material clamped between the gate and the material hole will be mixed with other materials entering the storage tank, causing pollution; at the same time, the existing There is no cleaning mechanism on the storage tank, and the traditional manual cleaning method is used to clean the inside of the tank. The cleaning time is long, the labor intensity of the workers is high, and the cleaning effect is average.
