Description
Technical Field

[0002] In industrial production, circulating water is mainly applied in the cooling water system, also known as circulating cooling water, which is used for condensing steam, cooling products or equipment. It is the part with the largest water consumption in industrial production, accounting for more than ninety percent of industrial water consumption.
[0003] In the circulating water system, with the increase of the usage time, impurities such as organic substances, inorganic salts, dust, and microorganisms will accumulate in the water. These impurities will not only affect the water quality, but may also cause problems such as corrosion and blockage of equipment pipelines, affecting production efficiency and product quality. Therefore, through solid-liquid separation technology, solid impurities in the water can be removed, the content of water nutrients can be reduced, the stability and cleanliness of the water quality can be maintained, so as to ensure the normal operation of equipment and the production quality of products, and improve the usage efficiency and safety of circulating water. However, for existing circulating water solid-liquid separation devices, the method of directly filtering the circulating water during transportation by using filtering components such as filter screens is generally adopted. Although the structure is simple and the manufacturing cost is low, with the increase of the circulating water volume, the filtered dregs will block the filter screen, requiring frequent cleaning and maintenance, increasing the usage cost, and affecting the solid-liquid separation efficiency of the circulating water. Therefore, this application provides a circulating water solid-liquid separation device to meet the requirements. Summary of the Utility Model

A connection port is provided on the side wall of the separation tank body along the tangential direction for transporting circulating water into the separation tank body along the tangential direction of the separation tank body. An air delivery ring is arranged at a position below the connection port in the separation tank body for guiding gas towards the upper part inside the separation tank body. A liquid collection cylinder is fixed in the middle of the separation tank body, and a separation cover for solid-liquid separation of circulating water is arranged at the top of the liquid collection cylinder.

[0011] Optionally, a diversion ring is arranged at a position above the separation cover inside the separation tank body, and the inner wall of the diversion ring gradually protrudes upward from the bottom to the middle of the separation tank body.
[0012] Optionally, a fixing rod is fixed to the bottom end of the liquid collecting cylinder, and the fixing rod is fixed to the inner wall of the separation tank body. The upper surface of the gas transmission ring gradually inclines downward toward the middle of the separation tank body.

[0016] Compared with the prior art, the utility model has at least the following beneficial effects:
[0017] In the above solution, by setting an air delivery ring and connection ports distributed along the tangential direction of the separation tank body, the circulating water is conveyed along the tangential direction of the separation tank body to the inside of the separation tank through the feed pipe and the connection ports. The high-pressure gas is conveyed into the air guiding channel in the air delivery ring through the air inlet pipe, and is blown obliquely upward along the direction of the circulating water delivery by a plurality of air outlet holes.

[0033] As Figure 1 and Figure 2 shown, an embodiment of the present utility model provides a circulating water solid-liquid separation device, including a separation tank body 1. A connection port 9 is provided on the side wall of the separation tank body 1 in a tangential direction. A feed pipe 2 is connected to the connection port 9 for conveying circulating water into the separation tank body 1 along the tangential direction of the separation tank body 1. An air delivery ring 10 is arranged at a position below the connection port 9 inside the separation tank body 1. An air inlet pipe 3 for delivering air towards the air delivery ring 10 is arranged on the side wall of the separation tank body 1 for delivering gas towards the upper part inside the separation tank body 1. A liquid collection cylinder 11 is fixed in the middle inside the separation tank body 1. A separation cover 12 for solid-liquid separation of circulating water is arranged at the top of the liquid collection cylinder 11. A drain pipe 4 communicated with the bottom inside the liquid collection cylinder 11 is arranged on the side wall of the separation tank body 1. The circulating water is conveyed into the separation tank body 1 along the tangential direction of the separation tank body 1 through the feed pipe 2 and the connection port 9, and high-pressure gas is conveyed to the air delivery ring 10 through the air inlet pipe 3 and blown upwards. Thus, while the circulating water conveyed into the separation tank body 1 is conveyed along the inner wall of the separation tank body 1, it is blown upwards along the inner wall of the separation tank body 1 by the high-pressure gas. After being blown to the top inside the separation tank body 1, the circulating water falls onto the separation cover 12 under the action of gravity. The separation cover 12 separates the solid and liquid of the circulating water. The separated circulating water falls into the liquid collection cylinder 11 and is discharged through the drain pipe 4. The separated slag is on the surface of the separation cover 12 and falls into the bottom inside the separation tank body 1 under the scouring of the subsequent circulating water. During the whole process of solid-liquid separation of the circulating water, the method of combining pneumatic blowing and gravity separation is adopted, which has the advantages of anti-blocking and high efficiency, and can realize the efficient solid-liquid separation of the circulating water.
[0034] As Figure 2 and Figure 3As shown, a gas guiding channel 16 is circumferentially formed inside the gas transmission ring 10. The gas guiding channel 16 is connected to the air inlet pipe 3. A plurality of air outlet holes 17 communicating with the gas guiding channel 16 are formed at the top of the gas transmission ring 10. The air outlet holes 17 are inclined and distributed in the direction of circulating water transportation. High-pressure gas is transported into the gas guiding channel 16 inside the gas transmission ring 10 through the air inlet pipe 3, and then is blown obliquely upward along the direction of circulating water transportation by the plurality of air outlet holes 17, so that the circulating water transported into the separation tank body 1 can be blown upward along the inner wall of the separation tank body 1. A diversion ring 13 is arranged at a position above the separation cover 12 inside the separation tank body 1. The inner wall of the diversion ring 13 gradually protrudes upward from the bottom to the middle of the separation tank body 1. Guided by the inclined inner wall of the diversion ring 13, the circulating water blown to the top of the separation tank body 1 can gather towards the middle of the separation tank body 1 above the separation cover 12, which is beneficial for the circulating water to fall on the separation cover 12 for gravity separation. A fixing rod 14 is fixed to the bottom end of the liquid collecting cylinder 11. The fixing rod 14 is fixed on the inner wall of the separation tank body 1 for supporting and fixing the liquid collecting cylinder 11. The upper surface of the gas transmission ring 10 gradually inclines towards the middle of the separation tank body 1, which is beneficial for the separated slag to fall into the bottom of the separation tank body 1.
[0035] As Figure 2 and Figure 4 shown, the separation cover 12 includes a bottom shell 18 fixed to the top end of the liquid collecting cylinder 11 and a filter screen 19 fixed to the top of the bottom shell 18. The bottom shell 18 and the filter screen 19 are arranged in a symmetric bowl-shaped structure. The bowl-shaped filter screen 19 is beneficial for the solid-liquid separation of the circulating water, and the separated slag can be smoothly washed down by the subsequent circulating water to avoid blockage. The bowl-shaped bottom shell 18 is beneficial for the separated circulating water to fall into the liquid collecting cylinder 11.
[0036] As Figure 1 , Figure 2 and Figure 5 shown, the bottom end of the separation tank body 1 is set as a conical structure, and a slag discharge pipe 15 is connected to the bottom end of the separation tank body 1. A slag discharge mechanism 5 for discharging the solid slag separated inside the separation tank body 1 is installed on the slag discharge pipe 15; the slag discharge mechanism 5 includes a guiding pipe 20 communicated with the slag discharge pipe 15, a screw rod 21 rotatably installed inside the guiding pipe 20, a slag discharge port 23 arranged at the bottom of the far end of the guiding pipe 20 from the slag discharge pipe 15, and a motor 22 installed on the slag discharge pipe 15 for driving the screw rod 21 to rotate. The screw rod 21 extends into the slag discharge pipe 15. The separated slag is on the surface of the filter screen 19 and falls into the slag discharge pipe 15 at the bottom of the separation tank body 1 under the flushing of the subsequent circulating water. After a certain amount of slag accumulates at the bottom of the separation tank body 1, the motor 22 is started to drive the screw rod 21 to rotate, and the slag can be discharged; a support plate 6 is fixedly sleeved at the bottom end of the separation tank body 1. Vertical support columns 7 are fixedly arranged at the four corners of the bottom of the support plate 6 for supporting and fixing the entire separation tank body 1. A suspension rod 8 for hoisting the slag discharge port 23 is also arranged at the bottom of the support plate 6 to ensure the stability of the slag discharge port 23.
[0037] The working principle of the technical solution provided by the present utility model is as follows:
[0038] During use, the circulating water is conveyed into the separation tank body 1 along the tangential direction of the separation tank body 1 via the feed pipe 2 and the connection port 9. At the same time, the high-pressure gas is conveyed into the air guide channel 16 in the air delivery ring 10 via the air inlet pipe 3, and then blown obliquely upward along the circulating water conveying direction by a plurality of air outlet holes 17. Thus, while the circulating water conveyed into the separation tank body 1 is conveyed along the inner wall of the separation tank body 1, it is blown upward along the inner wall of the separation tank body 1 by the high-pressure gas, and is guided by the inclined inner wall of the diversion ring 13, and converges towards the middle of the separation tank body 1 above the separation cover 12. At this time, the circulating water falls onto the filter screen 19 in the separation cover 12 under the action of gravity. The filter screen 19 separates the solid and liquid of the circulating water. The separated circulating water falls into the liquid collection cylinder 11 and is discharged via the drain pipe 4. The separated slag is on the surface of the filter screen 19 and falls into the slag discharge pipe 15 at the bottom of the separation tank body 1 under the scouring of the subsequent circulating water. After a certain amount of slag accumulates at the bottom of the separation tank body 1, the motor 22 is started to drive the screw rod 21 to rotate, and the slag can be discharged. During the entire solid-liquid separation process of the circulating water, the pneumatic blowing and floating and gravity separation are combined, which has the advantages of high efficiency and anti-blocking on the basis of realizing the solid-liquid separation of the circulating water.

In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the following preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without the description of these details. In addition, in order to avoid unnecessary confusion to the essence of the present utility model, well-known methods, processes, procedures, components and circuits are not described in detail.
[0040] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
