Description

Technical Field

[0001] This utility model relates to casting equipment, and in particular to a mixing and casting equipment. Background Technology

[0002] Existing mixing and casting equipment includes a base, a mixing tank, and a casting pipeline. Multiple raw materials in a certain proportion are placed in the mixing tank, mixed, and heated to form a molten casting material. The casting material then flows from the mixing tank into the casting pipeline. The casting pipeline includes a delivery pipe, multiple branch pipes, and multiple casting valves. Each branch pipe is arranged along the length of the delivery pipe, with one end connected to the delivery pipe. Each branch pipe is equipped with a corresponding two-way casting valve. When the mixing and casting equipment stops casting, the casting valves switch from the open to the closed state. At this time, the area in the branch pipes between the casting valves and the delivery pipes is approximately a dead zone, where casting material easily accumulates. The casting material cools easily and adheres to the inside of the branch pipes, which can easily clog the casting pipeline after prolonged use. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a mixing and casting device that can reduce the risk of refractory material accumulating in the casting pipeline.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] Reference Figures 1 to 4This invention relates to a mixing and casting device, comprising a base, a mixing tank 100, and a casting pipeline 200. The mixing tank 100 is disposed on the base and has a mixing inlet 110 and a mixing outlet 120. The mixing tank 100 also includes a heater. The casting pipeline 200 is disposed on the base and includes a delivery pipe 210 and at least two casting valves 220 arranged along the length of the delivery pipe 210. Each casting valve 220 is a three-way valve disposed on the delivery pipe 210 and has an inlet 221, a casting outlet 222, and a flow outlet 223. 3. Along the length of the conveying pipe 210, the flow outlets 223 and inlets 221 of two adjacent pouring valves 220 are connected in sequence. The pouring valves 220 have a pouring state and a flow state. In the pouring state, the inlet 221 is connected to the pouring outlet 222; in the flow state, the inlet 221 is connected to the flow outlet 223. The inlet 221 of the pouring valve 220 at the first end is connected to the mixing outlet 120 of the mixing tank 100 through the conveying pipe 210.

[0033] The casting valve 220 is a three-way valve and is directly installed on the conveying pipe 210. Initially, the casting valve 220 is in the flow state. When casting is required, one of the casting valves 220 switches to the casting state, while the other casting valves 220 remain in the flow state. This allows the casting material flowing out of the mixing tank 100 to flow directly through the conveying pipe 210 and several casting valves 220 in the flow state to the casting valve 220 in the casting state, and then flow out through the casting outlet 222. When the casting valve 220 switches from the casting state to the flow state, the conveying pipe 210 and each casting valve 220 are approximately straight-through without any dead ends, thereby reducing the risk of casting material accumulating in the casting pipeline 200.

[0034] In this embodiment, a cleaning assembly 300 is also included. The cleaning assembly 300 is disposed on the base and includes a detergent storage tank 310, a detergent pump 320, a gas cleaning pump, a first cleaning pipeline 330, and a second cleaning pipeline 340. The detergent storage tank 310 is provided with a return port 311 and a cleaning outlet 312. The return port 311 is connected to the flow outlet 223 of the pouring valve 220 located at the end through the first cleaning pipeline 330 and the delivery pipe 210. The mixing tank 100 is provided with a cleaning inlet 130. The cleaning outlet 312 is connected to the cleaning inlet 130 of the mixing tank 100 through the second cleaning pipeline 340. The detergent pump 320 is disposed in the second cleaning pipeline 340, and the outlet of the gas cleaning pump is connected to the second cleaning pipeline 340. A cleaning component 300 is provided. After the pouring pipe 200 and mixing tank 100 are used up, the cleaning component 300 can be used to clean the pouring pipe 200 and mixing tank 100. The cleaning component 300, mixing tank 100 and pouring pipe 200 form an approximately circular loop, which can reduce the use of cleaning agents during cleaning, thereby reducing environmental pollution.

[0035] Specifically, after the pouring pipeline 200 and mixing tank 100 are used up, the pouring valve 220 is switched to the flow state. The detergent pump 320 pumps the detergent from the detergent storage tank 310 into the mixing tank 100 through the second cleaning pipeline 340. The detergent then flows through the mixing tank 100 into the pouring pipeline 200, directly through the delivery pipe 210 and multiple pouring valves 220. The detergent then flows back to the detergent storage tank 310 through the first cleaning pipeline 330. The detergent then passes through the detergent pump 320 again, circulating for cleaning, thus fully utilizing the detergent and reducing its usage. After the detergent has circulated for a period of time, the cleaning pump stops, and the gas cleaning pump starts and blows air into the second cleaning pipeline 340, removing the detergent from the mixing tank 100 and the pouring pipeline 200.

[0036] In this embodiment, the cleaning assembly 300 further includes two cleaning on-off valves 350. One cleaning on-off valve 350 is located at the end of the first cleaning pipeline 330 near the pouring valve 220, and the other cleaning on-off valve 350 is located at the end of the second cleaning pipeline 340 near the mixing tank 100. By providing two cleaning on-off valves 350, the cleaning on-off valves 350 remain open during the pouring process of the mixing tank 100 and the pouring pipeline 200, preventing cleaning agent from entering the mixing tank 100 and the pouring pipeline 200. When the mixing tank 100 and the pouring pipeline 200 need cleaning, the two cleaning on-off valves 350 can be opened, allowing the cleaning agent to circulate through the mixing tank 100 and the pouring pipeline 200, making the cleaning process relatively simple.

[0037] In this embodiment, the cleaning assembly 300 further includes an air valve 360 ​​and a liquid valve 370. The second cleaning pipeline 340 includes a cleaning pipe 341 and an air inlet pipe 342. The cleaning outlet 312 of the detergent storage tank 310 is connected to the cleaning inlet 130 of the mixing tank 100 through the cleaning pipe 341. The liquid valve 370 and the cleaning on / off valve 350 are both connected to the cleaning pipe 341. The outlet of the air inlet pipe 342 is connected to the cleaning pipe 341. The outlet of the gas cleaning pump is connected to the inlet of the air inlet pipe 342. Along the length of the cleaning pipe 341, the liquid valve 370 is located between the cleaning on / off valve 350 and the detergent storage tank 310, and the outlet of the air inlet pipe 342 is located between the liquid valve 370 and the cleaning on / off valve 350. The air valve 360 ​​is connected to the air inlet pipe 342.

[0038] When cleaning the mixing tank 100 and the pouring pipeline 200 with cleaning agent, both cleaning on / off valves 350 are opened, and the liquid passage valve 370 is also opened. At this time, the gas passage valve 360 ​​is closed. The cleaning agent is pressurized by the cleaning agent pump 320 and can flow sequentially along the cleaning pipe 341, the mixing tank 100, the pouring pipeline 200, and the first cleaning pipeline 330. Since the gas passage valve 360 ​​is closed, the cleaning agent will not flow to the gas cleaning pump. After the cleaning agent cleaning is completed, the liquid valve 370 is closed and the air valve 360 ​​is opened. The gas cleaning pump pumps air in, and the air flows along the cleaning pipe 341, mixing tank 100, pouring pipe 200, and first cleaning pipe 330, driving the cleaning agent back into the cleaning agent storage tank 310. At this time, because the liquid valve 370 is closed, the cleaning agent can no longer flow through the cleaning pipe 341 to the mixing tank 100, thus allowing the cleaning agent to be returned and stored in the cleaning agent storage tank 310. The installation of the air valve 360 ​​and the liquid valve 370 ensures that the cleaning process using cleaning agent and the cleaning process using air do not interfere with each other, allowing them to be carried out alternately and independently, thus improving the overall cleaning effect.

[0039] In this embodiment, a sampling tube 410 and a sampling valve 420 are also included. One end of the sampling tube 410 is connected to the delivery pipe 210, and the other end of the sampling tube 410 is located between the end pouring valve 220 and the cleaning on / off valve 350. The sampling valve 420 is located within the sampling tube 410. With the sampling tube 410 and sampling valve 420 in place, the pouring material output from the mixing tank 100 at the initial startup can flow through all the pouring valves 220 before the sampling valve 420 is opened and samples are taken through the sampling tube 410 for testing. This tests whether the mixing tank 100 and the pouring pipeline 200 are sufficiently clean, reducing the risk of pouring material quality problems. After sampling is completed, the sampling valve 420 is closed. At this time, the sampling tube 410 does not affect the operation and cleaning process of the pouring pipeline 200.

[0040] In this embodiment, the base is provided with a mold casting area 600, and the casting outlets 222 of all casting valves 220 face the same direction and towards the mold casting area 600. The uniform orientation of the casting outlets 222 towards the mold casting area 600 facilitates the rational layout of subsequent pipelines and makes casting the mold easier.

[0041] In this embodiment, the base is equipped with a control module, which is electrically connected to the pouring pipe 200 and the cleaning assembly 300. The control module provides the physical basis for the automated control of the pouring and cleaning processes of the mixing and pouring equipment.

[0042] Specifically, the control module can be controlled by a PLC, a single-sided machine, or a microcomputer. In this embodiment, all valves can be electrically controlled valves, and their operating status can be controlled by a circuit.

[0043] In this embodiment, the casting valve 220 is detachably mounted on the delivery pipe 210. Specifically, the casting valve 220 is installed on the delivery pipe 210 by a vacuum clamp, and the casting valve 220 is removed by disassembling the vacuum clamp. It is conceivable that in other embodiments, the casting valve 220 may also be detachably mounted on the delivery pipe 210 by bolt fastening.

[0044] In this embodiment, the mixing tank 100 is connected to at least two raw material inlet pipes 510, the inlets of which are connected to the mixing inlet 110. Each raw material inlet pipe 510 is equipped with a feed valve 520. By providing multiple raw material inlet pipes 510, raw materials can be fed in separately when the feed valves 520 are open, facilitating the adjustment of the mixing ratio of the raw materials.

[0045] Specifically, the mixing tank 100 may be equipped with two, three, four or more raw material inlet pipes 510, and the mixing tank 100 is equipped with the same number of raw material inlets as the raw material inlet pipes 510.

[0046] In this embodiment, the pouring pipe 200 is equipped with eight pouring valves 220 to meet the requirements of continuous pouring in multiple stages. It is conceivable that in other embodiments, the pouring pipe 200 may include two, three, or more pouring valves 220, which can be selected by those skilled in the art according to actual needs.

[0047] Specifically, the mixing and casting equipment of this utility model is used as follows.

[0048] During the casting process, the feed valve 520 is opened, one of the casting valves 220 is switched to the casting state, and the remaining casting valves 220 remain in the flow state. The cleaning on / off valve 350, the air valve 360, the liquid valve 370, and the sampling valve 420 are all in the closed state. At this time, the casting material flowing out of the mixing tank 100 can flow directly through the conveying pipe 210 and into the mold through the casting valve 220 in the casting state.

[0049] During the cleaning process, all pouring valves 220 are initially in the open state, while the feed valve 520, air valve 360, and sampling valve 420 are closed. The two cleaning on-off valves 350 and the liquid valve 370 are opened, and the cleaning agent pump 320 is started to circulate the cleaning agent for a period of time. Subsequently, the liquid valve 370 is closed, and the air valve 360 ​​is opened. The gas cleaning pump is started, and compressed air is used to blow the cleaning agent from the mixing tank 100, pouring pipeline 200, and first cleaning pipeline 330 back to the cleaning agent storage tank 310. After cleaning is completed, the two cleaning on-off valves 350 and the air valve 360 ​​are closed.

[0050] The aforementioned mixing and casting equipment eliminates the need for individual cleaning of each casting valve, thus improving cleaning efficiency. Furthermore, the delivery pipe 210 can utilize a smaller diameter to reduce the amount of casting material remaining in the pipe during each mold-casting switch of the casting valve 220, which could lead to inaccurate casting volume measurement.

[0051] Specifically, in this embodiment, the cleaning on / off valve 350, the air valve 360, the liquid valve 370, and the sampling valve 420 are all two-way valves.

[0052] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0053] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
