Description

Technical Field

[0001] The utility model relates to the technical field of cooling, in particular to a cooling tower of a chiller unit. Background Art

[0002] In the production process of lead-acid batteries, cooling water is required for cooling in the acid preparation process and the formation process. In the acid preparation process, a large amount of heat will be generated when concentrated acid is added to pure water, and the temperature of the acid solution must be kept below 40 degrees Celsius when adding acid. In order to be able to start production quickly, the acid solution needs to be cooled in time. During the formation process, a large amount of heat will also be generated inside the battery, so the battery needs to be cooled. Cooling water is generally used for cooling. After the cooling water is heated and discharged, a cooling tower is generally required to reduce the temperature of the cooling water before it is transported to the chiller unit. The cooling tower is generally installed outdoors.

[0003] When the cooling tower is working, the cooling water is dispersed and then blown by the flowing air, thereby reducing the temperature of the cooling water. Generally, the cooling water flows downward from the top of the tower, and the air flows upward from the top of the tower. Since the cooling tower is generally set up outdoors, when there is dusty weather or catkins or poplar catkins floating in the air in spring, the air flowing upward from the bottom of the tower is likely to carry dust or catkins into the cooling tower body. The impurities entering the tower body are likely to block the cooling water pipeline, thereby affecting the service life. Therefore, preventing impurities from entering the cooling tower is a very important technical issue to consider.

[0004] In the prior art, a patent document entitled "Anti-wind and sand cooling tower" with application number CN202322428026.3 discloses a cooling tower that can prevent dust from entering the tower body. The airflow enters the guide cavity from the outside of the cooling tower body through the air inlet and is first separated by natural sedimentation, and then contacts the guide plate. The sand and gravel are further separated from the airflow by the blocking of the guide plate, and then enter the filter for re-filtration. The clean air after multiple filtrations enters the interior of the cooling body. The device uses a cooling tower to cool the air and can prevent sand and gravel from entering the filter. It does not cool the cooling water. When the air flows into the tower body, part of the sand and gravel will be blocked by the guide plate and further separated and fall down. Part of the sand and gravel will be blocked by the filter cotton, and part of the sand and gravel blocked by the filter cotton will remain between the filter cotton and the guide plate. When the filter cotton is removed for cleaning or replacement, the sand and gravel blocked by the filter cotton can easily enter the tower body. And the filter cotton of the cooling tower is not convenient to disassemble for cleaning or replacement. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0044] Example 1: Reference Figure 3-Figure 6 As shown, a cooling tower of a chiller unit includes a tower body 1, and an exhaust assembly 10 is arranged at the upper end of the tower body 1. The lower end of the tower body 1 is connected to an outlet pipe 11. The lower end of the tower body 1 is fixedly connected to a filling pipe 12. Cooling water can be added to the tower body 1 through the filling pipe 12.

[0045] The exhaust assembly 10 includes a bracket 9 fixed in the tower body 1 , a motor is fixed on the bracket 9 , and an impeller is fixed on the output shaft of the motor.

[0046] A distributor 7 is provided at the lower end of the exhaust assembly 10, and the distributor 7 is communicated with the inlet pipe 8. The cooling water enters the distributor 7 through the inlet pipe 8, and the distributor 7 can distribute the cooling water entering the tower body 1.

[0047] A packing layer 6 is arranged in the tower body 1 below the distributor 7. After the cooling water flows through the packing layer 6, the packing layer 6 can further disperse the cooling water.

[0048] A filtering and intercepting assembly is arranged on the side wall of the tower body 1 below the packing layer 6 .

[0049] The filtering and intercepting assembly includes a sleeve body 2 sleeved on the outside of the tower body 1, a lower cone sleeve 13 is arranged in the lower end of the annular cavity between the sleeve body 2 and the tower body 1, the small end of the lower cone sleeve 13 faces downward, the large end of the lower cone sleeve 13 is fixed to the inner edge of the sleeve body 2, an annular gap is arranged between the small end of the lower cone sleeve 13 and the tower body 1, an upper cone sleeve 14 is sleeved on the tower body 1 above the lower cone sleeve 13, the small end of the upper cone sleeve 14 faces upward, and the small end of the upper cone sleeve 14 is fixed. On the tower body 1, an annular gap is provided between the large opening end of the upper cone sleeve 14 and the sleeve body 2, a plurality of inner holes 101 are provided on the side wall of the tower body 1 between the upper cone sleeve 14 and the packing layer 6, a filter unit is sealed and inserted in the inner hole 101, an outer hole 201 corresponding to the inner hole 101 is provided on the sleeve body 2, a sealing plate 3 is sealed and inserted in the outer hole 201, a sealing ring is sleeved on the sealing plate 3, and the sealing plate 3 is sealed and inserted in the outer hole 201 through the sealing ring thereon. The sealing plate 3 is fixedly connected to the corresponding filter unit, and the filter unit can pass through the outer hole 201.

[0050] The filter unit includes an inner frame 1011, which is sealed and inserted in the inner hole 101. Specifically, a sealing ring is sleeved on the inner frame 1011, and the inner frame 1011 is sealed and inserted in the inner hole 101 through the sealing ring thereon, and a filter screen 1012 is fixed in the inner frame 1011. The inner frame 1011 is fixedly connected to the sealing plate 3 through a plurality of connecting rods 15.

[0051] The motor of the exhaust assembly 10 is started, and the motor drives the impeller to rotate. During the rotation of the impeller, the air outside the tower body 1 passes through the annular cavity between the casing 2 and the tower body 1 and then passes through the filter 1012 to enter the tower body 1. The upward air contacts the downward cooling water, thereby cooling the cooling water. The cooled cooling water is discharged through the outlet pipe 11.

[0052] Due to the lower cone sleeve 13 and the upper cone sleeve 14, a baffle channel is formed at the lower end of the annular cavity between the casing 2 and the tower body 1. When air flows through the baffle channel, sand and gravel with large particle size in the air can be separated from the air and discharged from the annular cavity under the action of gravity. The filter screen 1012 can filter small particles of impurities, catkins and poplar catkins.

[0053] Since the small end of the upper cone sleeve 14 faces upward, the small end of the upper cone sleeve 14 is fixed on the tower body 1, and an annular gap is provided between the large end of the upper cone sleeve 14 and the casing body 2. When sand and gravel fall onto the upper cone sleeve 14, the sand and gravel can fall through the annular gap between the large end of the upper cone sleeve 14 and the casing body 2 under the guidance of the outer cone surface of the upper cone sleeve 14.

[0054] Since the small end of the lower cone sleeve 13 faces downward, the large end of the lower cone sleeve 13 is fixed to the inner edge of the sleeve body 2, and an annular gap is provided between the small end of the lower cone sleeve 13 and the tower body 1. When sand and gravel fall onto the lower cone sleeve 13, the sand and gravel can fall through the annular gap between the small end of the lower cone sleeve 13 and the tower body 1 under the guidance of the inner cone surface of the lower cone sleeve 13.

[0055] When the filter 1012 needs to be removed, the sealing plate 3, the connecting rod 15, the inner frame 1011 and the filter 1012 are moved toward the outside of the tower body 1, and the inner frame 1011 can pass through the outer hole 201. After the inner frame 1011 and the filter 1012 pass through the outer hole 201, the impurities on the filter 1012 can be cleaned.
