Description

Technical Field

[0001] This utility model relates to a ceramic pump body casting and molding production line, belonging to the technical field of ceramic centrifugal pump production equipment. Background Technology

[0002] Ceramic centrifugal pumps significantly extend the service life of their main flow components—such as the front pump cover, impeller, pump body, and rear pump cover—by replacing the original metal material with wear-resistant and corrosion-resistant ceramic. This improvement leverages the excellent corrosion and wear resistance of ceramic to fill these components. The ceramic pump body is formed by injecting liquid ceramic slurry into a mold with a pump body cavity, creating a ceramic pump blank, which is then sintered at high temperatures. Currently, slurry casting of ceramic pump blanks requires individual mold casting, hindering batch production and resulting in low efficiency. This is a bottleneck in ceramic centrifugal pump production, significantly impacting overall production efficiency. Therefore, there is an urgent need for a ceramic pump body casting production line capable of batch casting of ceramic pump blanks to improve casting efficiency and ultimately, the overall production efficiency of ceramic centrifugal pumps. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a ceramic pump body casting production line that can batch cast ceramic pump blanks, thereby improving the casting production efficiency of ceramic pump blanks and the production efficiency of ceramic centrifugal pumps.

[0004] The purpose of this utility model is achieved as follows:

[0005] A ceramic pump body casting production line includes a slurry storage tank, a pressure tank, a vacuum pump, a high-pressure gas source, and molds; the slurry storage tank and the pressure tank are connected by pipelines; the pressure tank is connected to the vacuum pump and the high-pressure gas source by pipelines respectively; the pressure tank is provided with an outlet pipeline, which is connected to several molds respectively.

[0006] Furthermore, the number of molds does not exceed ten.

[0007] Furthermore, the outlet pipeline includes a main pipeline connected to the pressure tank and several branch pipelines spaced laterally along the longitudinal direction of the main pipeline; each branch pipeline is connected to a mold.

[0008] Furthermore, the branch pipeline forms a 60° angle with the main pipeline in terms of the direction of slurry flow.

[0009] Furthermore, the pressure tank is equipped with a slurry level display tube and a pressure gauge; pressure gauges and shut-off valves are respectively installed on the pipelines connecting the pressure tank to the slurry storage tank, vacuum pump, and high-pressure gas source.

[0010] Furthermore, the high-pressure air source is compressed air.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model connects a slurry storage tank, a pressure tank, and a mold via pipelines. By creating a negative pressure inside the pressure tank, the liquid ceramic slurry in the slurry storage tank is automatically drawn into the pressure tank. Then, high-pressure gas is introduced into the pressure tank to create a positive pressure, which simultaneously presses the ceramic slurry into multiple molds, thereby realizing the casting of ceramic pump blanks, improving the casting production efficiency of ceramic pump blanks, and improving the production efficiency of ceramic centrifugal pumps.

[0017] Slurry level display tube 21, main pipeline 51, branch pipeline 52. Detailed Implementation

[0018] See Figures 1-2 This utility model relates to a ceramic pump body casting production line, comprising a slurry storage tank 1, a pressure tank 2, a vacuum pump 3, a high-pressure air source 4, and molds 6; the slurry storage tank 1 and the pressure tank 2 are connected by pipelines; the pressure tank 2 is connected to the vacuum pump 3 and the high-pressure air source 4 by pipelines respectively; the pressure tank 2 is provided with an outlet pipeline 5, and is connected to several molds 6 respectively through the outlet pipeline 5. Considering that the fluidity of the slurry will decrease as the pipeline distance increases, a set of outlet pipelines 5 is generally connected to no more than ten molds 6; the high-pressure air source 4 is compressed air;

[0019] The outlet pipeline 5 includes a main pipeline 51 connected to the pressure tank 2 and several branch pipelines 52 arranged longitudinally and laterally along the main pipeline 51. Each branch pipeline 52 is connected to a mold 6. There are no more than ten branch pipelines 52 on a main pipeline 51, and each branch pipeline 52 forms a 60° angle with the direction of the slurry flow channel in the main pipeline 51 to reduce the resistance when the slurry flows from the main pipeline 51 into the branch pipeline 52. The diameter of the main pipeline 51 is larger than the diameter of the branch pipeline 52.

[0020] The pressure tank 2 is equipped with a slurry level display tube 21 and a pressure gauge, which are used to indicate the remaining slurry and internal pressure in the pressure tank 2, respectively; a pressure gauge and a shut-off valve are respectively installed on the pipelines connecting the pressure tank 2 to the slurry storage tank 1, the vacuum pump 3, and the high-pressure air source 4.

[0021] During operation, each mold 6 is connected to the branch pipeline 52, and the valves of each pipeline are closed. A vacuum pump 3 is used to extract air from the pressure tank 2 to create a negative pressure. In this embodiment, the negative pressure value is -0.1 to -0.2 MPa. The negative pressure in the tank draws the liquid ceramic slurry from the slurry storage tank 1 into the pressure tank 2. Then, the valves of the pipeline between the slurry storage tank 1 and the pressure tank 2 are closed, and compressed air is introduced into the pressure tank 2 to raise the pressure inside the tank to 1.0 to 1.5 MPa. The positive pressure then forces the slurry in the pressure tank 2 into each mold 6 sequentially through the main pipeline 51 and the branch pipeline 52. The ceramic slurry flows from the slurry storage tank 1 to the pressure tank 2 and finally to the mold 6, achieving automated mass production and realizing the purpose of mass casting of ceramic pump blanks. This improves the casting efficiency of ceramic pump blanks and the production efficiency of ceramic centrifugal pumps.

[0022] Additionally, it should be noted that the above-described specific implementation is merely an optimized solution of this patent, and any modifications or improvements made by those skilled in the art based on the above concept are within the scope of protection of this patent.
