Description

Technical Field

[0001] The present invention belongs to the technical field of filtration and separation, and particularly relates to a cooling tower using a bamboo grid filler energy-saving and environmental protection device. Background Art

[0002] As a key heat dissipation device in industrial production and refrigeration and air-conditioning systems, the core function of a cooling tower is to cool the circulating water through the heat exchange between water and air. This device uses water as the circulating coolant and utilizes the triple action principles of evaporation heat dissipation, convective heat transfer, and radiative heat transfer to discharge the waste heat absorbed in the system into the atmospheric environment in the form of steam volatilization. A typical cooling tower adopts a barrel-shaped structure design. During operation, heat exchange is generated through the contact between the water curtain and the air flow, thereby continuously maintaining the working temperature of the circulating water system and ensuring the normal operation of the equipment. With the acceleration of the industrialization process, its application scope has been extended to many important fields such as electric power, chemical industry, and data centers.

[0003] However, due to the long-term exposure of the cooling tower to the open environment, the characteristics of continuous contact between the spray water tank and the outside world lead to serious pollution problems. Pollutants such as suspended particulate matter, microorganisms, and dust in the air continuously invade the water circulation system, and at the same time, the mineral components carried by the water body itself and the corrosion products of the equipment form a composite deposit. These impurities continuously accumulate inside the cooling tower, not only causing physical obstacles such as clogging of the filler layer and uneven spraying, but also significantly reducing the heat conduction efficiency. Summary of the Invention

[0020] The cooling tower provided in this embodiment of an energy-saving and environmental protection device using bamboo grid fillers, compared with the prior art, the water passing through the filler layer 102 falls on the surface of the sieve plate 201, and impurities in the water (such as algae and calcified particles) are intercepted on the upper surface of the sieve plate 201, and the purified water falls into the recycling system 104; the power unit 40 drives the impurity removal cylinder 30 to rotate around the axis of the sieve plate 201, and the impurity removal cylinder 30 sucks the impurities on the upper surface of the sieve plate 201 into the sieve box 202 during rotation, facilitating the centralized treatment of impurities. The present invention screens out the impurities in the water and then concentrates them into the sieve box 202 for treatment, so that the impurities will not accumulate in the cooling tower, thereby not only reducing physical obstacles such as blockage of the filler layer 102 and uneven spraying, but also improving the heat conduction efficiency.

[0030] In some embodiments, see Figure 1 The power unit 40 includes a driving cylinder 401 and a driving member (not shown); the driving cylinder 401 is rotatably connected to the inner wall of the notch 2011; the driving member is transmission-connected to the driving cylinder 401, and is used to drive the driving cylinder 401 to rotate with the axis of the sieve plate 201 as the rotation axis.

[0031] It should be noted that the driving member is a waterproof motor, which is connected to the driving cylinder 401 through a gear set. A water guide cover is provided above the driving member. The setting of the water guide cover prevents water from falling on the driving member, thereby extending the service life of the driving member.

[0032] The driving member starts to drive the driving cylinder 401 to rotate through the gear set, and the driving cylinder 401 drives the impurity removal cylinder 30 to rotate, so that the impurity removal cylinder 30 sucks all the impurities on the upper surface of the screen plate 201 into the screen box 202 to avoid leaving dead corners.

[0033] In some embodiments, see Figure 2 and Figure 3 The impurity removal cylinder 30 includes a cylinder body 301 and a suction piece 302; the axis of the cylinder body 301 is parallel to the radial direction of the sieve plate 201, one end of the cylinder body 301 extends into the driving cylinder 401 and the two are fixedly connected, the outer periphery of the cylinder body 301 is provided with an impurity inlet 3011, and the end of the cylinder body 301 extending into the driving cylinder 401 is provided with an impurity outlet 3012; the suction piece 302 is fixedly connected to the cylinder body 301, and the suction piece 302 has an inlet 3021 facing the upper surface of the sieve plate 201 and an outlet 3022 connected to the impurity inlet 3011, and the inlet 3021 extends along the radial direction of the sieve plate 201.

[0034] It should be noted that the suction member 302 can be a suction machine, which sucks the impurities on the surface of the sieve plate 201 into the cylinder body 301 by suction.

[0035] During the rotation of the driving cylinder 401, the impurity removing cylinder 30 is driven to rotate. The rotation of the impurity removing cylinder 30 causes the cylinder body 301 and the suction member 302 to rotate synchronously, so as to cover the entire surface of the sieve plate 201 and avoid leaving dead corners.

[0036] In some embodiments, referring to Figure 3 and Figure 4 a pushing unit 50 is provided in the cylinder body 301. The pushing unit 50 includes a telescopic member 501, a pushing plate 502 and a reciprocating unit; the telescopic member 501 is slidably connected in the cylinder body 301, and the telescopic direction of the telescopic member 501 is perpendicular to the axis of the cylinder body 301; the pushing plate 502 is fixedly connected to the telescopic end of the telescopic member 501; the reciprocating unit is connected to the telescopic member 501 and is used to drive the telescopic member 501 to reciprocate along the axis direction of the cylinder body 301.

[0037] Wherein, when the telescopic member 501 moves towards the impurity outlet 3012, the telescopic member 501 extends so that the bottom end of the pushing plate 502 abuts against the inner bottom wall of the cylinder body 301; when the telescopic member 501 moves away from the impurity outlet 3012, the telescopic member 501 retracts so that the pushing plate 502 is separated from the inner bottom wall of the cylinder body 301.

[0038] The reciprocating unit drives the telescopic member 501 to reciprocate in the cylinder body 301, and the telescopic member 501 drives the pushing plate 502 to reciprocate in the cylinder body 301. During the reciprocating movement of the telescopic member 501, when the telescopic member 501 moves towards the impurity outlet 3012, the telescopic member 501 extends so that the pushing plate 502 moves downward until it abuts against the inner bottom wall of the cylinder body 301, so that the pushing plate 502 pushes all the impurities attached to the inner bottom wall of the cylinder body 301 into the impurity outlet 3012; when the telescopic member 501 moves away from the impurity outlet 3012, the telescopic member 501 retracts so that the pushing plate 502 moves upward and is separated from the inner bottom wall of the cylinder body 301, so that the pushing plate 502 will not bring back the impurities during the return process.

[0039] In some embodiments, referring to Figure 3 a partition plate 3013 is fixedly connected to the cylinder body 301. The plate surface of the partition plate 3013 is parallel to the axis of the cylinder body 301. The partition plate 3013 divides the internal space of the cylinder body 301 into an impurity removal chamber 3014 communicating with the impurity inlet 3011 and a power chamber 3015 communicating with the impurity removal chamber 3014. The telescopic member 501 is slidably arranged on the bottom wall of the partition plate 3013, and the reciprocating unit is arranged in the power chamber 3015.

[0040] When the telescopic member 501 extends, the bottom end of the push plate 502 is separated from the bottom wall of the partition plate 3013; when the telescopic member 501 retracts, the top end of the push plate 502 abuts against the bottom wall of the partition plate 3013.

[0041] When the telescopic member 501 moves away from the impurity outlet 3012, the telescopic member 501 retracts, causing the push plate 502 to move upward and separate from the inner bottom wall of the cylinder body 301 until it abuts against the bottom wall of the partition plate 3013. During the return process of the push plate 502, it will not bring back impurities and can scrape off the impurities adhering to the bottom wall of the partition plate 3013, preventing impurities from accumulating in the cylinder body 301.

[0042] Long-term adhesion of impurities to the reciprocating unit will damage the reciprocating unit and reduce its service life; by dividing the cylinder body 301 into two chambers by the partition plate 3013, when impurities are sucked into the cylinder body 301, the impurities enter the impurity removal chamber 3014, reducing the possibility of impurities entering the power chamber 3015, preventing impurities from adhering to the reciprocating unit, and ensuring the service life of the reciprocating unit.

[0043] In some embodiments, refer to Figures 3 to 5 , the partition plate 3013 is provided with a guiding groove 30131 that communicates the impurity removal chamber 3014 and the power chamber 3015, and the guiding groove 30131 extends along the axial direction of the cylinder body 301. The reciprocating unit includes a reciprocating shaft 503, a power member (not shown), and a transmission block 504; the reciprocating shaft 503 is rotatably connected to the inner wall of the impurity removal chamber 3014, and two spiral transmission grooves 5031 are formed on the outer circumference of the reciprocating shaft 503. The ends of the two transmission grooves 5031 are interconnected and are symmetrically distributed along the axis of the reciprocating shaft 503; the power member is drivingly connected to the reciprocating shaft 503 for driving the reciprocating shaft 503 to rotate about the axis of the cylinder body 301; one end of the transmission block 504 is fixedly connected to the fixed end of the telescopic member 501, and the other end passes through the guiding groove 30131 and is inserted into the transmission groove 5031.

[0044] It should be noted that the power member is a motor, and the end of the output shaft of the power member is directly fixedly connected to the center of the end of the reciprocating shaft 503.

[0045] When the power member is started to drive the reciprocating shaft 503 to rotate, the transmission block 504 moves during the rotation of the reciprocating shaft 503 through the transmission groove 5031, so that the transmission block 504 reciprocates in the guiding groove 30131, and thus the transmission block 504 drives the telescopic member 501 to reciprocate in the cylinder body 301.

[0046] In some embodiments, refer to Figure 2 , the outer wall of the driving cylinder 401 is connected with a cleaning unit 60. The cleaning unit 60 includes a cleaning comb 601 extending along the radial direction of the sieve plate 201, and the cleaning comb 601 abuts against the upper surface of the sieve plate 201.

[0047] The driving cylinder 401 rotates to drive the cleaning comb 601 to rotate. During the rotation process, the cleaning comb 601 is always in contact with the surface of the sieve plate 201, so that the cleaning comb 601 cleans the sieve holes of the sieve plate 201, making the sieve plate 201 less likely to be blocked. At the same time, impurities attached to the sieve plate 201 are loosened, making it easier for the impurities to be sucked away by the adsorbent.

[0048] In some embodiments, see Figure 2 and Figure 6 The cleaning comb 601 is rotatably connected to the outer wall of the driving cylinder 401. The cleaning unit 60 also includes a rotating member 602 which is transmission-connected to the cleaning comb 601. The rotating member 602 is used to drive the cleaning comb 601 to rotate with the radial direction of the screen plate 201 as the rotation axis.

[0049] It should be noted that the rotating member 602 is a waterproof motor. The rotating member 602 is fixedly mounted on the outer wall of the driving cylinder 401. The output shaft of the rotating member 602 is directly fixedly connected to the end center of the cleaning comb 601. A water guide cover is also provided above the rotating member 602. The setting of the water guide cover prevents water from falling on the rotating member 602, thereby extending the service life of the rotating member 602.

[0050] When the cleaning comb 601 rotates around the axis of the sieve plate 201 , the rotating member 602 starts to drive the cleaning comb 601 to rotate around its own central axis, thereby enhancing the cleaning degree of the sieve plate 201 by the cleaning comb 601 .

[0051] In some embodiments, see Figure 2 The cleaning comb 601 is arranged on the front side of the impurity removing barrel 30.

[0052] It should be noted that the rotation direction of the driving cylinder 401 is the front. If the driving cylinder 401 rotates counterclockwise, the counterclockwise direction is the front side; if the driving cylinder 401 rotates clockwise, the clockwise direction is the front side. Figure 2 The middle driving cylinder 401 rotates clockwise.

[0053] After the cleaning comb 601 loosens the impurities attached to the sieve plate 201 , the loosened impurities are immediately sucked away by the suction member 302 , thereby preventing the loosened impurities from firmly adhering to the sieve plate 201 again, thereby improving the cleaning efficiency.

[0054] In some embodiments, see Figure 1 The opening of the screen box 202 is sleeved on the outer circumference of the driving cylinder 401, and the screen box 202 and the driving cylinder 401 are detachably connected.

[0055] Optionally, the detachable connection between the screen box 202 and the driving cylinder 401 may be fixed by bolts.

[0056] The rotation of the driving cylinder 401 drives the rotation of the sieve box 202. During the rotation of the sieve box 202, all the water inside will be thrown out, and the impurities in the sieve box 202 are retained, thereby reducing the residual water in the sieve box 202. The sieve box 202 and the driving cylinder 401 are arranged in a detachable connection manner, which is convenient for cleaning the impurities in the sieve box 202.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
