Description

Technical Field

[0001] This utility model relates to the technical field of twin-screw pumps, and in particular to a multi-head rubber twin-screw pump. Background Technology

[0002] Some twin-screw pumps have one end of the screw connected to the motor, which drives the screw to rotate, thus engaging with the other screw and discharging liquid from one end to the other. Some pumps do not have protective measures at the connection between the motor and the screw, leaving the connection exposed to the outside, which can cause dust to stick to the connection and affect the operation of the pump.

[0003] In the prior art, patent document CN217926277U discloses a twin-screw pump, a base, a housing fixedly connected to the upper surface of the base, a motor fixedly connected to the upper surface of the base and located on one side of the housing; a protective assembly, the protective assembly including a fixed cylinder fixedly connected to the side wall of the housing, a sliding groove formed on the side wall of the fixed cylinder, a movable cylinder disposed inside the sliding groove, a fixed strip fixedly connected to the top of the movable cylinder, a threaded hole formed on the outer wall of the fixed cylinder, a threaded post threadedly connected inside the threaded hole; a first screw is provided at the output end of the motor, a first fixed sleeve and a second fixed sleeve are fixedly connected to the inner wall of the housing, and a second screw is rotatably connected inside the first fixed sleeve and the second fixed sleeve.

[0004] During use, it was found that while the fixed cylinder is fixedly installed on the outer shell and can prevent dust, it causes interference when one end of the screw is connected to the motor, affecting the connection efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-head rubber twin-screw pump.

[0006] This utility model discloses a multi-head rubber twin-screw pump, comprising a base, a motor, a housing, an inlet pipe, an outlet pipe, a positioning ring, and a threaded hole. The motor and housing are respectively mounted on the top of the base. The inlet pipe and outlet pipe are respectively mounted on the housing. The positioning ring has a threaded hole. A protective component is also included, located between the motor and the housing and detachably connected to the positioning ring. In use, the motor output end connects to a set of screws inside the housing, which are located inside the positioning ring. The protective component, mounted on the positioning ring, provides dust protection at the connection between the motor output end and the set of screws. The protective component does not interfere with the screw connection between the motor output end and the housing. When the protective component is not needed, it can be disassembled, improving flexibility.

[0007] Preferably, the protective assembly includes an outer arc-shaped plate, a first bolt, a side plate, a second bolt, a nut, and an inner arc-shaped plate assembly. There are two sets of outer arc-shaped plates, each set of which is threadedly connected to a set of first bolts. The first bolts are threaded into threaded holes. Each set of outer arc-shaped plates has a set of side plates at its upper and lower ends, and each set of side plates has a circular hole. The second bolt passes through the circular hole and is threaded into the nut. The inner arc-shaped plate assembly is slidably disposed inside the two sets of outer arc-shaped plates. In use, the two sets of inner arc-shaped plate assemblies are placed inside the two sets of outer arc-shaped plates. Then, the first bolt is threaded into the threaded hole, and the second bolt passes through the circular hole and is threaded into the nut, thus forming an outer cylinder with the two sets of outer arc-shaped plates. The position of the inner arc-shaped plate assembly inside the two sets of outer arc-shaped plates is then adjusted to improve flexibility.

[0008] Preferably, the inner arc plate assembly includes an inner arc plate body, a strip groove, a fixing seat, and a No. 3 bolt. There are two sets of inner arc plate bodies. Each set of inner arc plate bodies has a set of strip grooves on its outer side. Each set of outer arc plates has a fixing seat at its outer end. Each set of fixing seats is threadedly connected to a set of No. 3 bolts. The two sets of outer arc plates are combined to form an outer cylinder, and the two sets of inner arc plate bodies form an inner cylinder. By adjusting the position of the inner arc plate body in the outer arc plate and rotating the No. 3 bolt, the No. 3 bolt is tightened against the corresponding inner arc plate body. The far end of the inner arc plate body away from the outer arc plate is pressed against the motor, thereby completing the dustproof operation.

[0009] Preferably, it also includes protrusions, and protrusions are installed on the inner arc plate body; the operator can adjust the position of the inner arc plate body in the outer arc plate by means of the protrusions, thereby improving the ease of operation.

[0010] Preferably, the outer wall of the inner arc-shaped plate body is coated with a smooth, wear-resistant coating.

[0011] Preferably, it also includes a sealing gasket, with a sealing gasket installed at the end of the inner arc plate body away from the outer arc plate; the two sets of inner arc plate bodies and the two sets of sealing gaskets cooperate to fit tightly against the motor, improving dustproof sealing.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the motor output end is connected to a set of screws inside the housing. The set of screws is inside the positioning ring, so that the protective component is installed on the positioning ring and performs dustproof operation at the connection between the motor output end and the set of screws. The protective component cannot interfere with the connection between the motor output end and the screws in the housing. When the protective component is not needed, it can be disassembled by itself, improving flexibility. Attached Figure Description
