Description

Technical Field

[0001] The utility model relates to the technical field of lithium ore resource roasting and lithium extraction, in particular to a cooling tower for reducing wind and sand erosion. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the heat exchange between water and air flow to generate steam, and the steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer to dissipate the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature. The device is generally barrel-shaped, hence the name cooling tower. This method can meet most cooling needs, but it has shortcomings for some areas with strong sandstorms all year round. When encountering sandstorm weather, sand particles in the atmosphere often enter the cooling tower from the air inlet of the cooling tower, affecting the normal operation of the equipment, so it is necessary to install a filter to filter the air inlet. However, in the existing cooling tower air inlet structure, the front end of the air inlet mostly uses a filter made of steel wire to filter the sand particles. The filter made of steel wire can usually filter larger sand particles, but cannot filter fine sand particles with a diameter of 0.3 microns, so that fine sand particles with a diameter of 0.3 microns can easily enter the cooling tower and affect the normal operation of the equipment, which may cause cooling tower failure, thereby shortening the service life of the cooling tower. At the same time, since the filter made of steel wire is mostly directly fixed on the air inlet, the filter made of steel wire is fixedly installed on the cooling tower, which is inconvenient to remove the filter for repair and maintenance, and thus it is inconvenient to install and remove the filter on the cooling tower; for this reason, it is necessary to provide a cooling tower that reduces sand erosion to solve the above problems. Utility Model Content

[0003] The utility model aims to solve the problem that the filter screen made of steel wire in the prior art cannot filter the fine sand particles with a diameter of 0.3 microns, and thus proposes a cooling tower for reducing sand erosion.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a cooling tower for reducing wind and sand erosion, comprising a cooling tower body, a plurality of legs are fixedly arranged at equal intervals in a ring at the bottom of the cooling tower body, four air inlets are opened at equal intervals in a ring on the lower end side wall of the cooling tower body, shutters are fixedly arranged inside the four air inlets, adjustment components are fixedly arranged at the front and rear ends of the cooling tower body, arc-shaped filter screens are detachably arranged at both ends of the two adjustment components, and the four arc-shaped filter screens are respectively located outside the four shutters.

[0005] Furthermore, the curved filter is made of HEPA material, and the surface of the curved filter is coated with fire retardant paint.

[0006] Furthermore, the adjusting assembly includes a fixed seat, a driving motor, a bidirectional screw, and a groove. The fixed seat is vertically and fixedly arranged on the side wall of the cooling tower body. The driving motor is fixedly arranged at the bottom of the fixed seat. The groove is vertically opened inside the fixed seat. The output end of the driving motor is fixedly connected with a bidirectional screw. Bearings are arranged at both ends of the bidirectional screw, and the bidirectional screw is rotatably arranged in the groove through the bearings.

[0007] Furthermore, the adjusting assembly further includes threaded blocks, rectangular through holes, arc-shaped rods, and arc-shaped card slots. Threaded blocks are threadedly arranged at both ends of the bidirectional screw, and both threaded blocks are located in the groove. Rectangular through holes are opened on both the upper and lower sides of the fixed seat, and all four rectangular through holes are communicated with the groove. Arc-shaped rods are fixedly connected to both sides of the two threaded blocks, and the four arc-shaped rods are respectively slidably arranged in the four rectangular through holes.

[0008] Furthermore, all four arc-shaped rods are closely attached to the outer wall of the cooling tower body. Arc-shaped card slots are opened at both ends of the two groups of arc-shaped rods on both sides of the two threaded blocks that are close to each other, and the arc-shaped card slots are opened on the inner side of the arc-shaped rods. The arc-shaped filter net is detachably installed between the two arc-shaped rods through the arc-shaped card slots.

[0009] The beneficial effects of the present utility model are as follows:

[0010] 1. In the present utility model, the arc-shaped filter net made of HEPA material can remove at least 99.97% of the particles with a diameter of 0.3 microns in the air. The characteristic of the HEPA net is that air can pass through, but fine particles cannot pass through. It is the most effective filtering medium for pollutants such as smoke and dust. By applying a fireproof coating to the arc-shaped filter net made of HEPA material, the main purpose is to prevent the sparks splashed during equipment maintenance welding from igniting the arc-shaped filter net, resulting in equipment damage and production stoppage.

[0011] 2. In the present utility model, when the arc-shaped filter net needs to be disassembled, by starting the driving motor to drive the bidirectional screw to rotate clockwise, the two threaded blocks move away from each other, driving the two arc-shaped rods to move away from each other, so as to facilitate taking out the arc-shaped filter net from the arc-shaped card slot, and further facilitating disassembling the arc-shaped filter net from the cooling tower body, thereby facilitating the repair and maintenance of the arc-shaped filter net.
