Abstract
Description
Technical Field
[0001] The present application relates to the technical field of triazone production, and in particular to a rinsing overflow device used in triazone production. Background Art
[0002] Triazinones are a class of heterocyclic compounds with potential biological activity. Pymetrozine, a typical example of a triazinon compound with insecticidal activity, is highly effective, low-toxic, and environmentally friendly. It is primarily used as an intermediate in the manufacture of the herbicide metribuzin.
[0003] In the prior art, triazone production requires rinsing, which involves adding rinse water. After centrifugation, the rinse water is discarded and piped to a wastewater tank. However, in actual production, when the centrifuge power is too high, a large amount of water is discarded. Furthermore, due to the fixed diameter and long length of the pipe, the high internal water pressure prevents the water from being promptly transported to the wastewater tank, affecting the centrifugal efficiency. Utility Model Content
[0004] In view of the above problems, the embodiments of the present application provide a rinsing overflow device for triazone production, which can effectively avoid the phenomenon of water outlet obstruction of the centrifuge due to insufficient aperture of the pipeline, thereby further improving the working efficiency of the centrifuge.
[0005] According to one aspect of an embodiment of the present application, a rinsing overflow device for use in triazone production is provided. The rinsing overflow device for use in triazone production includes a buffer water tank, a centrifuge, and a wastewater tank. The water outlet of the centrifuge is connected to the buffer water tank through a first outlet pipe. A second outlet pipe is provided at the bottom of the buffer water tank. The end of the second outlet pipe is connected to the wastewater tank. A closing valve is provided on the second outlet pipe. The middle part of the buffer water tank is located below the horizontal plane of the first outlet pipe and is connected to an overflow pipe. The end of the overflow pipe is connected to a vent pipe and a return pipe respectively through a double-ended sleeve. The other end of the vent pipe extends upward and is provided with a filter assembly at its end. The return pipe is connected to a third outlet pipe at one end away from the double-ended sleeve. The third outlet pipe extends to and is connected to the wastewater tank.
[0006] In some embodiments, the bottom of the buffer water tank is connected to a conical groove, and the second water outlet pipe is connected to the bottom of the conical groove.
[0007] In some embodiments, there are two overflow pipes, and the two overflow pipes are symmetrically arranged on the outer periphery of the buffer water tank. Correspondingly, there are two vent pipes, two return pipes, and two third water outlet pipes.
[0008] In some embodiments, the water outlet pipe is supported on the ground, and the two third water outlet pipes are connected to the second water outlet pipe via support frames.
[0009] In some embodiments, one end of the third water outlet pipe away from the wastewater pool is fixedly connected to the outer wall of the buffer water tank.
[0010] In some embodiments, the filter assembly includes an end cover, which is screwed onto the outer wall of the vent pipe, and a plurality of air holes are opened in the middle of the end cover.
[0011] In some embodiments, a rust removal box is fixed to the outer periphery of the vent pipe, and the rust removal box is connected to the vent pipe through a quantitative valve.
[0012] The beneficial effects of the present application are as follows: in the present application, by providing a buffer water tank, the water in the centrifuge can quickly flow into the buffer water tank through the first water outlet pipe for collection, and the water in the buffer water tank can again flow into the wastewater pool through the second water outlet pipe or the third water outlet pipe to complete collection. Since the buffer water tank is close to the centrifuge, the length of the first water outlet pipe is short and its diameter can be appropriately expanded under cost-controllable conditions, so that the water pressure inside the first water outlet pipe is relatively small. When the centrifuge has high power and a large discharge volume, the water discharged can be collected in a timely and smooth manner through the buffer water tank, thereby avoiding the phenomenon of water outlet obstruction of the centrifuge and further improving the working efficiency of the centrifuge. On the other hand, the present application also provides an overflow pipe, a vent pipe, and a third water outlet pipe, so that when the water outlet rate of the second water outlet pipe is low, the water in the buffer water tank can be discharged into the wastewater pool through the overflow pipe, the return pipe and the third water outlet pipe in sequence, further preventing the water in the buffer water tank from flowing back into the centrifuge, and the setting of the vent pipe enables the equipment to be connected to the external atmosphere, and the drainage process is smoother and faster.

[0019] The following will describe in detail the embodiments of the technical solution of the present application in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only used as examples and cannot be used to limit the scope of protection of the present application.

[0020] Specifically, please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of a rinsing overflow device for triazone production provided in an embodiment of the present application. Figure 2A schematic diagram of the cross-sectional structure of the buffer water tank provided in an embodiment of the present application. The rinsing overflow device 100 used in triazone production includes a buffer water tank 120, a centrifuge 110, and a wastewater tank 130. In the embodiment of the present application, the buffer water tank 120 and the wastewater tank 130 are both prior art. The centrifuge 110 is used to centrifuge the rinsed triazone to "dry" the triazone. The water discharged will eventually flow into the wastewater tank 130 for collection after passing through the buffer water tank 120. The water outlet of the centrifuge 110 is connected to the buffer water tank 120 through the first outlet pipe 140. The water discharged from the centrifuge 110 will flow into the buffer water tank 120 through the first outlet pipe 140. Naturally, the overall height of the buffer water tank 120 should be lower than the overall height of the centrifuge 110 and the first outlet pipe 140. A second outlet pipe 150 is located at the bottom of the buffer water tank 120. The end of the second outlet pipe 150 is connected to the wastewater tank 130. A shut-off valve 151 is installed on the second outlet pipe 150. Under normal operating conditions, the shut-off valve 151 is open, allowing water in the buffer water tank 120 to continuously flow into the wastewater tank 130 through the second water storage pipe. When the centrifuge 110 is shut down, the shut-off valve 151 can be closed. An overflow pipe 121 is connected to the middle of the buffer water tank 120, below the level of the first outlet pipe 140. Overflow pipe 121 is used to drain water from the buffer water tank 120 when the preset liquid level in the buffer water tank 120 exceeds a certain limit. The preset liquid level is adjustable based on the height of the connection between the overflow pipe 121 and the buffer water tank 120. The connection between the overflow pipe 121 and the buffer water tank 120 is located below the horizontal plane of the first outlet pipe 140, thereby ensuring that the water in the buffer water tank 120 can be discharged from the overflow pipe before it flows back into the centrifuge 110 (when the liquid level in the buffer water tank 120 is higher than that in the centrifuge 110, the water in the buffer water tank 120 will flow back into the centrifuge 110). The end of the overflow pipe 121 is connected to the vent pipe 123 and the return pipe 124 through a double-ended sleeve 122. It should be noted that for ease of installation, the vent pipe 123 and the return pipe 124 can be the same pipe. After the overflow pipe 121 is connected to the middle of the pipe, the upper portion of the pipe becomes the vent pipe 123, and the lower portion of the pipe becomes the return pipe 124. The vent pipe 123 is used to balance the air pressure inside the buffer water tank 120, so that the drainage of the entire device is not hindered by atmospheric pressure and the drainage is smooth. Under the action of gravity, the water in the overflow pipe 121 will flow downward into the return pipe 124, and the return pipe 124 will transport the water in the overflow pipe 121 to the third water outlet pipe 160. The other end of the vent pipe 123 extends upward and is equipped with a filter assembly 125 at its end. The installation of the filter assembly 125 can prevent solid particles or impurities in the external environment from entering the device through the vent pipe 123 and causing pipe blockage and other problems.One end of the return pipe 124 away from the double-ended sleeve 122 is connected to a third water outlet pipe 160 , which extends to and is connected to the wastewater tank 130 . The third water outlet pipe 160 and the second water outlet pipe 150 work independently, but both can transport water to the wastewater tank 130 .
[0021] As can be seen from the above, in the embodiment of the present application, by providing a buffer water tank 120, the water in the centrifuge 110 can quickly flow into the buffer water tank 120 through the first water outlet pipe 140 for collection, and the water in the buffer water tank 120 can flow into the wastewater pool 130 again through the second water outlet pipe 150 or the third water outlet pipe 160 to complete collection. Since the buffer water tank 120 is close to the centrifuge 110, the length of the first water outlet pipe 140 is short and its diameter can be appropriately expanded under cost-controllable conditions, so that the water pressure inside the first water outlet pipe 140 is relatively small. When the centrifuge 110 has high power and a large discharge volume, the water discharged can be collected in a timely and smooth manner through the buffer water tank 120, thereby avoiding the phenomenon of water outlet obstruction of the centrifuge 110 and further improving the working efficiency of the centrifuge 110. On the other hand, the present application also provides an overflow pipe 121, a vent pipe 123, and a third water outlet pipe 160, so that when the water outlet rate of the second water outlet pipe 150 is low, the water in the buffer water tank 120 can be discharged into the wastewater tank 130 through the overflow pipe 121, the return pipe 124 and the third water outlet pipe 160 in sequence, further preventing the water in the buffer water tank 120 from flowing back into the centrifuge 110, and the setting of the vent pipe 123 enables the device to be connected to the external atmosphere, and the drainage process is smoother and faster.
[0022] In some embodiments, the bottom of the buffer water tank 120 is connected to a tapered groove 126, and the second water outlet pipe 150 is connected to the bottom of the tapered groove 126. In the embodiment of the present application, through the above arrangement, the water in the buffer water tank 120 can be fully drained.
[0023] In some embodiments, there are two overflow pipes 121, symmetrically arranged around the periphery of the buffer water tank 120. Correspondingly, there are two vent pipes 123, two return pipes 124, and two third outlet pipes 160. In this embodiment, by providing two sets of overflow pipes 121, drainage efficiency is further increased.
[0024] In some embodiments, the second water outlet pipe 150 is supported on the ground, and the two third water outlet pipes 160 are connected to the second water outlet pipe 150 via support frames 170. In the embodiment of the present application, the above arrangement ensures the overall stability of the third water outlet pipes 160 and the second water outlet pipes 150, thereby enhancing the integrity of the device.
[0025] In some embodiments, the end of the third water outlet pipe 160 away from the wastewater tank 130 is fixedly connected to the outer wall of the buffer water tank 120. In the embodiment of the present application, through the above arrangement, after the end of the third water outlet pipe 160 is fixed to the outer wall of the buffer water tank 120, the third water outlet pipe 160 will be further reinforced to prevent it from shaking.
[0026] In some embodiments, the filter assembly 125 includes an end cap 125a, which is screwed onto the outer wall of the vent tube 123. A plurality of air holes 125b are defined in the center of the end cap 125a. In the embodiments of this application, a specific configuration of the filter assembly 125 is provided, which allows for convenient and simple component production. With this configuration, external impurities are blocked by the air holes 125b in the end cap 125a, minimizing the impact on normal air circulation.
[0027] In some embodiments, a rust removal box 123a is fixed to the outer periphery of the vent pipe 123, and the rust removal box 123a is connected to the vent pipe 123 via a metering valve 123b. In this embodiment of the present application, a rust remover can be placed in the rust removal box 123a, and the metering valve 123b is adjusted so that the rust remover in the rust removal box 123a can be slowly dripped from the vent pipe 123 to the return pipe 124, and further flowed from the return pipe 124 to the third water outlet pipe 160, thereby removing rust from each pipe. During the entire process, the operator only needs to complete the dripping of the rust remover, which greatly saves manpower.
[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
