DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 3As shown, a water treatment cooling pool includes a pool body 1, a first flow channel 13 for wastewater circulation is provided in the pool body 1, and the pool body 1 includes two first pool walls 11 arranged opposite to each other and two second pool walls 12 arranged opposite to each other, and the first pool walls 11 and the second pool walls 12 surround and form a rectangular frame. The two first pool walls 11 are respectively provided with a first inlet 111 and a first outlet 112, and the high-temperature printing and dyeing wastewater flows into the first inlet 111 through the first flow channel 13 and then flows out from the first outlet 112.

[0022] like Figure 1 As shown, a cylinder 4 is connected between the two second pool walls 12, and the two axial ends of the cylinder 4 are sealed and connected to the two second pool walls 12, respectively. The cylinder 4 is located in the first flow channel 13, and the cylinder 4 is axially penetrated and formed with a cavity, and the cavity of the cylinder 4 is isolated from the first flow channel 13. When the high-temperature wastewater flows through the outer wall of the cylinder 4, it produces a heating effect on the cylinder 4. The two second pool walls 12 are respectively provided with a second inlet 121 and a second outlet 122. The second inlet 121 is connected to a valve 2, and the valve 2 controls the coolant to enter the cylinder 4. When the coolant flows through the cylinder 4, the cylinder 4 is cooled and discharged from the second outlet 122, so that the high-temperature wastewater outside the cylinder 4 completes heat exchange with the coolant inside the cylinder 4 to reduce the temperature of the high-temperature wastewater. In subsequent treatment, the wastewater temperature is reduced to prevent excessive harmful gas from overflowing and reduce pollution.

[0023] like Figure 1 As shown, the second pool wall 12 provided with the second outlet 122 is fixedly connected with the plug post 3, and the plug post 3 is inserted into the cylinder 4 and the two are coaxially arranged.

[0024] like Figure 1 As shown, the plug post 3 is close to the end of the second pool wall 12 provided with the second inlet 121 (i.e. Figure 1 The upper end of the middle plug column 3 is provided with a connecting portion 32, such as Figure 2 As shown, the connecting portion 32 includes a ring body 321 , a cavity portion 322 is formed radially inside the ring body 321 , a through hole 3211 is radially provided on the ring body 321 , the through hole 3211 passes through the outer wall of the ring body 321 , and the through hole 3211 is communicated with the cavity portion 322 .

[0025] like Figure 1 As shown, the ring body 321 is fixedly connected with the spacer 5, and the spacer 5 is located near the second inlet 121. The spacer 5 includes a spacer ring 51 and an insert 52. The insert 52 is threadedly connected and inserted into the ring body 321. The insert 52 is partially located in the cavity portion 322. The spacer ring 51 is located on the side of the spacer 5 close to the second inlet 121 and on the side away from the ring body 321. The outer diameter of the spacer ring 51 matches the inner diameter of the cylinder 4, so that the spacer ring 51 divides the inner cavity of the cylinder 4 into a first cavity 41 and a second cavity 42. The first cavity 41 is connected to the second inlet 121, and the second cavity 42 is connected to the second outlet 122.

[0026] like Figure 1 , Figure 2 As shown, the plug post 3 is located in the second cavity 42, and the outer wall of the plug post 3 is provided with a spiral portion 31, which protrudes radially outward along the outer wall of the plug post 3 and forms a spiral shape. The inner diameter of the cylinder 4 is larger than the outer diameter of the spiral portion 31, so that a cooling liquid flow channel along the axial direction of the cylinder 4 is formed between the radial outer end of the spiral portion 31 and the inner wall of the cylinder 4, and the cooling liquid entering the second cavity 42 flows along the Figure 2 As shown, the flow is in the P direction, and during the flow, the wall surface of the cylinder 4 is cooled to complete the heat exchange.

[0027] The second cavity 42 includes a spiral flow channel 421, which is located on the side of the second cavity 42 radially away from the inner wall of the cylinder 4. The flow channel 421 is coaxial with the cylinder 4. The flow channel 421 is spirally distributed along the spiral portion 31. The coolant flows along the spiral portion 31. Figure 2 When the cooling liquid flows in the P direction as shown, the cooling liquid in the flow channel 421 flows in a spiral along the flow channel 421, so that the cooling liquid near the inner wall of the cylinder 4 also produces a spiral motion, thereby increasing the flow distance of the cooling liquid in the second cavity 42, increasing the heat exchange time, and improving the utilization rate of the cooling liquid.

[0028] like Figure 2 As shown, the partition 5 is provided with a third flow channel 53, and the third flow channel 53 axially passes through the partition 5, and one axial end of the through hole 3211 is connected with the second cavity 42, and the other axial end of the through hole 3211 is connected with the first cavity 41 through the cavity portion 322 and the third flow channel 53, so that the coolant in the first cavity 41 needs to pass through the third flow channel 53, the cavity portion 322, and the through hole 3211 to flow into the second cavity 42.

[0029] like Figure 3 As shown, there are eight through holes 3211 evenly distributed along the circumference of the ring body 321. Figure 2 Along the P direction, the axial direction T of the through hole 3211 is toward the spiral direction Q of the flow channel 421, so that when the coolant is ejected from the through hole 3211, it generates a flow rotation direction that is the same as the spiral direction Q of the flow channel 421, so that the coolant can flow along the flow channel 421 more smoothly and faster, thereby making it easier to drive the coolant close to the inner wall of the cylinder 4 to generate a spiral motion trajectory, thereby improving the heat exchange efficiency.
