Description

Technical Field

[0001] The utility model belongs to the technical field of cooling water return, and in particular relates to a return water confluence pressure reduction device. Background Art

[0002] In the production process of substrate glass, the relevant production equipment of important production processes such as kiln channels need to be cooled, and most of them use flowing water cooling. In the production and processing of some other industries, flowing water cooling is also often used. The cooling water return after passing through each water-cooling area generally converges into the return pipe at the end of the branch pipe and flows along the return pipe to the return tank. However, the flow velocity and water pressure of the return water flowing out of different water-cooling areas will be different, and turbulence is easy to form when converging. When the water flow velocity and water pressure are too large, it will cause the water flow impact force to be large, which will cause the inner wall of the return pipe to be over-pressurized and prone to bursting, affecting the service life of the pipe, high maintenance costs, and affecting the continuous production of the production line. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a return water confluence pressure reducing device which can reduce the impact during return water confluence, greatly reduce the possibility of return water main pipe bursting, extend its service life, reduce maintenance costs, and help ensure continuous operation of the production line.

[0004] The content of the utility model includes a confluence trough and a plurality of buffer troughs arranged on the side of the confluence trough, wherein the plurality of buffer troughs are separated from the plurality of confluence troughs by partitions, the top of the partitions being lower than the tops of the plurality of buffer troughs, and the water in the plurality of buffer troughs can overflow along the tops of the partitions and flow into the confluence trough; a water inlet is arranged on one side of the plurality of buffer troughs, the water inlets of the plurality of buffer troughs are correspondingly connected to a plurality of return water branch pipes, and baffles are arranged in the plurality of buffer troughs, and the baffles are arranged opposite to the water inlets and spaced apart in the buffer troughs.

[0005] Furthermore, the inner diameter of one end of the plurality of return water branch pipes connected to the water inlet gradually increases along the return water flow direction to form a trumpet-shaped terminal structure.

[0006] Furthermore, the top of the partition is lower than the center point of the water inlet.

[0007] Furthermore, the diameter of the baffle is greater than or equal to the diameter of the water inlet.

[0008] Furthermore, the spoiler is arranged in the buffer groove through a fixing rod.

[0009] Furthermore, a single spoiler is connected to more than two fixing rods, which are circumferentially distributed on the edge of the spoiler, and one end of the two or more fixing rods facing away from the spoiler is connected to a position on the outer edge of the water inlet in the buffer groove.

[0010] Furthermore, a plurality of the buffer grooves are arranged on the same side of the confluence groove.

[0011] Furthermore, the water inlet is arranged on a side of the buffer tank opposite to the partition.

[0012] Furthermore, two adjacent buffer grooves share the same side plate.

[0013] Furthermore, a return water main pipe is connected to the bottom of the confluence trough.

[0014] The beneficial effect of the utility model is that the return water of each production node flows along a plurality of return water branches. When the return water flows to the water inlet and enters the corresponding buffer tank, the water flow gradually becomes stable in the buffer tank and overflows from the top of the partition to the confluence tank as the water level rises. In this process, the setting of the baffle can block the impact direction of the water flow when it enters the buffer tank. The water flow will flow out along the side of the baffle between the water inlet and the baffle, thereby changing the direction and flow path of the water flow, causing the water flow to diffuse and rotate when passing through the baffle, thereby slowing down the water flow speed, reducing the impact force of the water flow entering the buffer tank, and reducing the wear and deformation of the buffer tank. Combined with the overflow of water through the partition, the large noise generated by high-speed water flow can be reduced, and impurities in the water flow can be precipitated in the buffer tank to improve the cleanliness of the return water. When the water flow finally enters the confluence tank, the water flow speed and pressure can be consistent, and the water flow finally flowing into the return water main along the confluence tank is more stable and has less impact force, which greatly reduces the possibility of the return water main bursting, extends its service life, reduces maintenance costs, and is conducive to ensuring the continuous operation of the production line.

[0019] like Figure 1-Figure 3As shown, the utility model provides a return water confluence pressure reduction device, including a confluence trough 1 and a plurality of buffer troughs 2, wherein the plurality of buffer troughs 2 are arranged on the side of the confluence trough 1, and the plurality of buffer troughs 2 are separated from the confluence trough 1 by a partition 3, and the top of the partition 3 is lower than the top of the plurality of buffer troughs 2, so as the water level in the plurality of buffer troughs 2 rises to the top position of the partition 3, the water in the plurality of buffer troughs 2 can overflow along the top of the partition 3 and flow into the confluence trough 1. A water inlet 21 is arranged on one side of the plurality of buffer troughs 2, and the water inlets 21 of the plurality of buffer troughs 2 are connected to a plurality of return water branch pipes 5, that is, one return water branch pipe 5 is connected to the water inlet 21 of one buffer trough 2, and a baffle 4 is arranged in the plurality of buffer troughs 2, and the baffle 4 is arranged opposite to the water inlet 21 in the buffer trough 2 and spaced apart.

[0020] The utility model is used to be arranged at the confluence of the return water of each branch, that is, to be arranged at the confluence between a plurality of return water branch pipes 5 and a return water main pipe 6. A plurality of return water branch pipes 5 are used to correspond to the water outlets of each production node, and the return water of each production node flows along a plurality of return water branch pipes 5. When the return water flows to the water inlet 21 and enters the corresponding buffer tank 2, its water flow gradually stabilizes in the buffer tank 2, and overflows from the top of the partition 3 to the confluence tank 1 as the water level rises. During this process, the setting of the baffle 4 can play a blocking role in the impact direction of the water flow when the water flows into the buffer tank 2. The water flow will flow out along the side of the baffle 4 between the water inlet 21 and the baffle 4, thereby changing the direction and flow path of the water flow, causing the water flow to diffuse and rotate when passing through the baffle 4, thereby slowing down the water flow speed, reducing the impact force of the water flow entering the buffer tank 2, and reducing the wear and deformation of the buffer tank 2. Combined with the overflow of water through the partition 3, the large noise generated by high-speed water flow can be reduced, and impurities in the water flow can be precipitated in the buffer tank 2 to improve the cleanliness of the return water. When the water flow finally enters the confluence tank 1, the water flow speed and pressure can be consistent, and the water flow when finally flowing into the return water main 6 along the confluence tank 1 is more stable and has a small impact force, which greatly reduces the possibility of the return water main 6 bursting, extends its service life, reduces maintenance costs, and is conducive to ensuring the continuous operation of the production line.

[0021] Compared with the buffer tank 2, the area of ​​the spoiler 4 is smaller, so the arrangement of the spoiler 4 is less costly than thickening and reinforcing the buffer tank 2 as a whole, and even if the spoiler 4 is made thicker, the cost is relatively small. If the spoiler 4 is damaged due to long-term impact of water flow, the replacement and maintenance cost will be much lower than the maintenance cost of the buffer tank 2.

[0022] like Figure 2 and Figure 3As shown, the inner diameter of one end of the return water branch pipes 5 connected to the water inlet 21 gradually increases along the return water flow direction to form a trumpet-shaped terminal structure 51. The return water branch pipes 5 are specifically connected to the corresponding water inlet 21 through the trumpet-shaped terminal structure 51. The setting of the trumpet-shaped terminal structure 51 expands the outlet area of ​​the end of the return water branch pipe 5, so that the water flow gradually diffuses when passing through the end of the return water branch pipe 5, thereby slowing down the water flow speed and reducing the water pressure. It can effectively further reduce the impact force of the water flow when entering the buffer tank 2, reduce noise, reduce the impact force of the water flow on the baffle plate 4, and extend the service life of the baffle plate 4, thereby improving the operating reliability and stability of the device and reducing the maintenance frequency and cost of the device.

[0023] The spacing between the baffle 4 and the water inlet 21 can be preferably the same as the diameter of the water inlet 21 to avoid the situation where the spacing is too small, resulting in excessive water flow resistance and excessive water pressure in the return branch 5, and the spacing is too large, resulting in the baffle 4 being unable to effectively play the role of buffering and reducing pressure. The top of the partition 3 is lower than the center point of the water inlet 21 to prevent damage to the buffer tank 2 and the return branch 5 due to excessive water pressure caused by too high a water level.

[0024] The diameter of the baffle plate 4 is greater than or equal to the diameter of the water inlet 21, so as to ensure that the baffle plate 4 can effectively block the flow and buffer the pressure drop.

[0025] The spoiler 4 is arranged in the buffer tank 2 by means of a fixing rod 41. Specifically, a single spoiler 4 is connected with two or more fixing rods 41, which are circumferentially distributed at the edge of the spoiler 4, and one end of the two or more fixing rods 41 away from the spoiler 4 is connected to the position at the outer edge of the water inlet 21 in the buffer tank 2, so as to fix the spoiler 4. This arrangement ensures the stability of the fixation of the spoiler 4 on the basis of ensuring that the spoiler 4 is opposite to the water inlet 21 and arranged at intervals, and will not affect the outflow of water from the side of the spoiler 4.

[0026] In the utility model, several buffer tanks 2 are arranged on the same side of the confluence tank 1, so that several return water branch pipes 5 can be located outside the same side of the confluence tank 1, and the water inlet 21 is arranged on the side opposite to the partition 3 in the buffer tank 2, so that the positions of several return water branch pipes 5 when connected to the buffer tank 2 are more orderly, and there will be no position interference between the return water branch pipes 5.

[0027] Two adjacent buffer tanks 2 share the same side plate, reducing material costs. The return water main pipe 6 is specifically connected to the bottom of the confluence tank 1. The water entering the confluence tank 1 flows into the return water main pipe 6 under the action of gravity, and the end of the return water main pipe is used to connect to the cooling water tank.
