Description

Technical Field

[0001] This utility model relates to the field of gear pump technology, and in particular to a gear pump foreign matter mixing and injection device. Background Technology

[0002] Liquefied natural gas (LNG) ships typically require gear pump foreign matter mixing and injection devices. These devices utilize the working characteristics of gear pumps to quantitatively extract and transport liquid materials from different storage tanks to a mixing zone. The gear pump drives the gears to rotate through the rotation of its shaft, realizing the process of liquid intake and discharge. During the transportation process, each material enters the mixing zone according to a set ratio, and is uniformly mixed through the mixing structure inside the device (such as stirring and extrusion). Finally, the mixed liquid is sprayed out through the discharge section to meet the needs of different production processes.

[0003] In existing gear pump foreign matter mixing and spraying devices, materials enter the gear pump through the feed pipe for mixing and pressurization, and are then sprayed out through the discharge pipe. However, before entering the gear pump, large particles of impurities remain in the material. These large particles increase wear inside the gear pump, affecting its service life and the mixing of materials. Furthermore, the mixing of materials is sometimes insufficient when sprayed out after being mixed and pressurized inside the gear pump, and the mixing degree is not further improved inside the discharge pipe. Moreover, it is difficult to adjust the spray pressure of the material after it has been pressurized inside the gear pump, which can result in excessive spray pressure.

[0004] Therefore, a gear pump foreign matter mixing and injection device is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art where the material is not sufficiently mixed after being mixed and pressurized inside the gear pump and then sprayed out. The mixing degree of the material is not improved again inside the discharge pipe. Moreover, it is not easy to adjust the pressure of the material after it is pressurized inside the gear pump, resulting in a situation where the material spray pressure is too high. Therefore, a gear pump foreign matter mixing and spraying device is proposed.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Design a gear pump foreign matter mixing and spraying device, including a base, a mounting seat fixed to the top of the base, a housing fixed to the top of the mounting seat, a gear pump body installed inside the housing, an inlet pipe installed on one side of the housing, a filter mechanism installed at the outer end of the inlet pipe, an outlet pipe installed on the other side of the housing, a spiral mixing mechanism installed inside the outlet pipe, a spray pipe installed at the outer end of the outlet pipe, and a spray intensity adjustment mechanism installed inside the spray pipe;

[0008] The spiral mixing mechanism includes a spiral blade, and mounting brackets are fixed at both ends of the discharge pipe. A rotating rod is rotatably mounted between the two mounting brackets, and the spiral blade is spirally fixed to the surface of the rotating rod.

[0009] The spray intensity adjustment mechanism includes an adjustment rod that is rotatably inserted into the interior of the spray pipe, and an adjustment plate is fixed to the surface of the adjustment rod.

[0010] Furthermore, the base is horizontally positioned, the outer casing is vertically positioned, a motor is installed at one end of the gear pump body, cover plates are sealed on both sides of the outer casing, and the motor is fixedly installed on the outside of the cover plates.

[0011] Furthermore, the feed pipe is horizontally arranged, and a connecting flange is fixed to its outer end. The side of the connecting flange has a groove, which is a circular groove structure.

[0012] Furthermore, the filtering mechanism includes a filter plate with sealing rings bonded to its two side edges, and the filter plate is installed inside the groove.

[0013] Furthermore, the inner edge of the groove is uniformly provided with positioning grooves, and a first magnetic block is fixed inside the positioning grooves.

[0014] Furthermore, a second magnetic block is fixed to the inner edge of the filter plate. The second magnetic block passes through the sealing ring, its inner end is inserted into the positioning groove, and it is attracted and connected to the first magnetic block.

[0015] Furthermore, the discharge pipe is horizontally arranged, the mounting bracket has a cross-shaped structure and is vertically arranged, the rotating rod is horizontally arranged, the spiral blade is horizontally rotatably installed inside the discharge pipe, the outer surface of the outer end of the discharge pipe has an external threaded surface structure, the spray pipe has an internal threaded surface structure, and is threadedly connected to the outer end of the discharge pipe.

[0016] Furthermore, the top end of the injection pipe has a connection hole, which is a threaded hole structure. The adjusting rod is a threaded rod structure and rotates through the connection hole. The adjusting plate is a rectangular plate structure and is vertically arranged at the outer end of the discharge pipe.

[0017] Furthermore, the adjusting rod is vertically arranged, and a nut is connected to its surface at the top of the spray pipe. A torsion bar is fixed to the top of the adjusting rod, and the torsion bar has a straight-line structure.

[0018] The gear pump foreign matter mixing and injection device proposed in this utility model has the following advantages:

[0019] 1. This utility model provides a spiral blade in the discharge pipe on one side of the outer shell. The spiral blade is rotatably installed in the discharge pipe via a rotating rod and a mounting bracket. Therefore, after the material is pressurized by the gear pump and enters the discharge pipe, it will drive the spiral blade to rotate. After the spiral blade rotates, it will rotate and mix the material again, thereby improving the mixing degree of the material.

[0020] 2. This utility model has a detachable spray pipe installed on the outside of the discharge pipe, and an adjustment plate installed inside the spray pipe via an adjustment rod. When the material is pressurized inside the gear pump and the material spray pressure is too high, the adjustment rod and adjustment plate can be rotated by the torsion bar. The adjustment plate can then block the sprayed material, reducing the spray speed and pressure, and maintaining the material at a reasonable spray pressure and speed.

[0021] 3. In this utility model, a flange is fixedly connected to the outer end of the feed pipe on the other side of the outer shell, and a filter plate is installed in the groove on the side of the flange. The filter plate is attracted and connected by the second magnetic block and the first magnetic block, and is positioned and installed between the filter plate and the flange. Therefore, the filter plate is sealed and installed at one end of the feed pipe to filter out large particles of impurities from the incoming material, thereby reducing the wear inside the gear pump.
