Description
Technical Field
[0001] This utility model relates to the field of liquid material conveying technology, and in particular to a centralized liquid material conveying device. Background Technology
[0002] Traditional liquid supply systems typically use tanks, pumps, and valves as independent components connected by external pipelines. This results in a loose overall structure, low integration, large size, significant space occupation, and low fluid transfer efficiency. Furthermore, the exposed pipelines are cluttered, affecting aesthetics and increasing the risk of leaks due to loose connections and aging pipes, thus increasing maintenance difficulty and costs. In addition, existing systems lack sufficient automation, relying heavily on manual valve operation during liquid addition to tanks and system supply, hindering precise control and remote management, and failing to meet the demands of modern intelligent manufacturing for process automation and intelligent monitoring. Summary of the Invention
[0003] In view of the problems mentioned above, such as complex and large liquid supply pipelines, low transmission efficiency, large footprint, and low degree of automation, it is necessary to propose a liquid supply device that realizes compact and intelligent liquid supply.
[0004] A liquid supply device includes a liquid tank, a pipe assembly, a collection tray, and a base, all of which are mounted on the base. The liquid tank stores liquid, the pipe assembly transports liquid, and the collection tray collects any liquid lost during transport. The base includes a base frame, a first support, and a second support. One end of the first support is fixed to the base frame, and the other end is connected to one end of the second support. The other end of the second support extends upward and is suspended in the air. The liquid tank is positioned on the base frame away from the first support, and one end of the pipe assembly is connected to the liquid tank. The pipe assembly is positioned between the liquid tank and the first support, achieving a compact arrangement of the liquid supply device.
[0005] Furthermore, a level gauge is provided on the outer wall of the liquid tank. The level gauge is fixed to the outer wall of the tank body by a flange and is used to measure the liquid level in the liquid tank, which serves as a measurement standard for determining whether to add liquid to the liquid tank.
[0006] Furthermore, the upper surface of the liquid tank is also provided with a liquid inlet, which includes a first bend, a first pneumatic valve, and a first interface pipe; the input end of the first pneumatic valve is provided with the first interface pipe through a flange, the output end of the first pneumatic valve is provided with the first bend through a flange, the other end of the first bend is connected to the upper surface of the tank body, and the other end of the first interface pipe is suspended for connecting to a pipe from the liquid pool.
[0007] The lower end face of the liquid tank is also provided with a drain port, which includes a second bend, a first straight pipe, a first manual valve, and a second interface pipe. One end of the second bend is directly connected to the bottom end face of the tank body, and the other end of the second bend is connected to one end of the first straight pipe. The other end of the first straight pipe is connected to the input end of the first manual valve, and the output end of the first manual valve is connected to one end of the second interface pipe, thereby realizing the smooth discharge of liquid in the liquid tank.
[0008] Furthermore, considering the problems of short service life and high failure rate of diaphragm pumps, two diaphragm pump pipelines are arranged in parallel in the pipeline assembly. That is, the pipeline assembly includes a first line with a first diaphragm pump and a second line with a second diaphragm pump. The first line and the second line are parallel lines. When the first line is working, the second line stops working, and when the second line is working, the first line stops working, thereby ensuring that the pipeline assembly can always be in operation and will not stop working due to inspection or maintenance.
[0009] The beneficial effects of this utility model are: it achieves the goals of smaller footprint, higher transmission efficiency, more compact pipeline components, and automated liquid supply in the liquid conveying device. Attached Figure Description

Obviously, the following description is some typical embodiments of this utility model. For those skilled in the art, other solutions can be obtained based on these embodiments without creative effort.
[0012] like Figures 1-4The image shows an implementation example of the liquid supply device described in this utility model being used to supply printing liquid to a sand mold 3D printing equipment.
[0013] In one embodiment, the liquid supply device includes a liquid tank 1, a pipe assembly 3, a liquid collection tray 4, and a base 2. The liquid tank 1, pipe assembly 3, and liquid collection tray 4 are all mounted on the base 2. The liquid tank 1 is used to store liquid, the pipe assembly 3 is used to transport liquid, and the liquid collection tray 4 is used to collect any liquid lost during transport. The base 2 includes a base frame 201, a first support 202, and a second support 203. One end of the first support 202 is fixed to the base frame 201, and the other end is connected to one end of the second support 203. The other end of the second support 203 extends upward and is suspended in the air. The liquid tank 1 is positioned on the base frame 201 away from the first support 202, and one end of the pipe assembly 3 is connected to the liquid tank 1. The pipe assembly 3 is positioned between the liquid tank 1 and the first support 202, achieving a compact arrangement of the liquid supply device. Specifically, the bottom frame 201 is composed of two square steel or I-beams of equal length arranged in parallel with a certain width between them. The liquid tank 1 is set at one end of the bottom frame 201 away from the first support 202 by a bracket. The first support 202 and the second support 203 form a support frame at a certain height above the bottom frame 201, which facilitates the installation and setting of the components of the pipe assembly 3 and facilitates the export of liquid material from a lower position to a higher position, which is convenient for the subsequent use of sand mold 3D printing equipment.
[0014] As a supplement to this embodiment, the liquid tank 1 includes a tank body 101, a level gauge 102, a first bend 103, a first pneumatic valve 104, a first interface pipe 105, a second bend 106, a first straight pipe 107, a first manual valve 108, and a second interface pipe 109. The level gauge 102 is fixed to the outer wall of the tank body 101 via a flange and is used to measure the liquid level in the liquid tank 1, serving as a measurement standard for determining whether to add liquid to the liquid tank 1. The first bend 103 is mounted on the upper surface of the tank body 101 via a flange, and the first pneumatic valve 104 is mounted on the first bend 103 via a flange, serving as a control valve for the liquid entering the liquid tank 1. To facilitate connection with the pipeline to the liquid pool, a first interface pipe 105 is also provided at the other end of the first pneumatic valve 104 relative to the first bend 103. That is, the input end of the first pneumatic valve 104 is connected to the first interface pipe 105 via a flange, and the output end of the first pneumatic valve 104 is connected to the first bend 103 via a flange. The other end of the first bend 103 is connected to the upper surface of the tank body 101, and the other end of the first interface pipe 105 is suspended for connection to the pipeline from the liquid pool. The bottom surface of the tank body 101 is also provided with a second bent pipe 106, a first straight pipe 107, a first manual valve 108, and a second interface pipe 109 for draining liquid. One end of the second bent pipe 106 is directly connected to the bottom surface of the tank body 101, and the other end of the second bent pipe 106 is connected to one end of the first straight pipe 107. The other end of the first straight pipe 107 is connected to the input end of the first manual valve 108, and the output end of the first manual valve 108 is connected to one end of the second interface pipe 109, thereby realizing the smooth discharge of liquid in the liquid tank 1 to facilitate the cleaning and maintenance of the liquid tank. In layman's terms, the first interface pipe 105 is the liquid inlet of the liquid tank 1, and the second interface pipe 109 is the liquid outlet of the liquid tank 1.
[0015] As a supplement to this embodiment, the pipeline assembly 3 includes a first line equipped with a first diaphragm pump and a second line equipped with a second diaphragm pump. The first and second lines are parallel lines. When the first line is operating, the second line stops operating, and when the second line is operating, the first line stops operating, thereby ensuring that the pipeline assembly 3 can always be in operation and will not stop operating due to maintenance or repair. Specifically, since the diaphragm pumps are relatively heavy, in order to avoid the suspended diaphragm pumps easily causing a heavy burden on the pipeline, both the first and second diaphragm pumps are mounted on the base frame 201 by brackets.
[0016] As a further supplement to this embodiment, the configuration of the first line includes a first tee pipe installed at the outlet of the liquid tank 1 via a flange. The first tee pipe has one input and two outputs. The input end of the first tee pipe is connected to the outlet of the liquid tank 1. Either of the two output ends of the first tee pipe is connected to a second pneumatic valve. The other end of the second pneumatic valve is connected to a first diaphragm pump. The output end of the first diaphragm pump is connected to a first check valve. The output end of the first check valve is connected to the input end of a filter 301. The output end of the filter 301 is connected to a flow meter 302. The output end of the flow meter 302 is connected to a liquid outlet 304, thereby achieving the purpose of outputting liquid from the liquid tank 1 through the first line. The second pneumatic valve is used to start or stop the first line.
[0017] As a further supplement to this embodiment, the configuration of the second line includes a first tee pipe installed at the outlet of the liquid tank 1 via a flange. The first tee pipe has one input and two outputs. The input end of the first tee pipe is connected to the outlet of the liquid tank 1. Either of the two output ends of the first tee pipe is connected to a third pneumatic valve. The other end of the third pneumatic valve is connected to a second diaphragm pump. The output end of the second diaphragm pump is connected to a second check valve. The output end of the second check valve is connected to the input end of a filter 301. The output end of the filter 301 is connected to a flow meter 302. The output end of the flow meter 302 is connected to a delivery outlet 304, thus achieving the purpose of outputting liquid from the liquid tank 1 through the second line. The third pneumatic valve is used to start or stop the second line.
[0018] As a further supplement to this embodiment, the output end of the flow meter 302 is also provided with a sampling outlet 303 for sampling liquid samples in the liquid tank 1, so as to facilitate real-time detection of liquid quality and performance and avoid sending unqualified liquid to the sand mold 3D printing equipment.
[0019] As a further supplement to this embodiment, in order to facilitate sampling and normal liquid material transportation, a manual valve is also provided between the flow meter and the sampling outlet. When sampling is required, the manual valve is manually operated to obtain the liquid material sample.
[0020] As a further supplement to this embodiment, in order to ensure the stability of liquid delivery, not only are valves provided at the front end of the first diaphragm pump and the second diaphragm pump, but a fourth pneumatic valve is also provided between the liquid delivery outlet 304 and the flow meter 302 to achieve dual control of each liquid delivery pipeline and avoid erroneous operation.
[0021] As a supplement to this embodiment, the liquid collection tray 4 is slidably mounted on the bottom frame 201 made of I-beam steel as a guide rail. The liquid collection tray 4 is a cuboid or cube groove with a certain depth and an open top, used to contain liquid that may leak or spill from the pipe assembly, thus avoiding environmental pollution caused by liquid leakage and achieving effective recycling of liquid.
[0022] In this embodiment, all valves and pipes are connected by flanges. In order to achieve a compact liquid supply device, the pipe assembly 3 is provided with both straight pipes and bends to facilitate the arrangement of the entire pipe assembly in the vertical space.
[0023] The operation process of the liquid supply device described in this utility model is as follows: 1) When the liquid level in the level gauge 102 is lower than the warning level, the signal is transmitted to the control module. The control module issues a liquid replenishment command, and the first pneumatic valve 104 opens to replenish the liquid from the liquid pool to the liquid tank. When the liquid level in the liquid tank is higher than the warning level, the control module issues a stop liquid replenishment command, and the first pneumatic valve 104 closes to stop replenishment. 2) When the sand mold 3D printing equipment needs liquid material, the sand mold 3D printing equipment sends a liquid material shortage command to the control module, the control module sends a liquid material supply command, the second pneumatic valve and the fourth pneumatic valve open, and the liquid material is delivered to the sand mold 3D printing equipment through the first line; 3) If the first diaphragm pump fails, a first fault command is issued. After receiving the first fault command, the control module closes the second pneumatic valve and opens the third pneumatic valve, switching the liquid delivery pipeline assembly to the second line to achieve continuous liquid supply to the sand mold 3D printing equipment. 4) When the liquid material in the sand mold 3D printing equipment reaches the required level, it sends a liquid material full command to the control module. The control module then sends a stop liquid supply command, and the second, third, and fourth pneumatic valves close simultaneously to stop supplying liquid to the sand mold 3D printing equipment.
[0024] The implementation of this technical solution makes the complex infusion pipeline more compact. By setting up two parallel infusion pipelines, it is ensured that the infusion supply device can always supply liquid normally, avoiding the interruption of the infusion supply operation and affecting the normal operation of subsequent operations. Furthermore, the double insurance through dual pneumatic valve control improves the stability and reliability of the infusion supply. The above embodiments are merely descriptions of a typical application of the technical solution of this utility model. Reasonable extensions can be made without requiring creative effort.
