Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a flangeless clamp-type split sand tank. Background Technology

[0002] Currently, the industry commonly uses a flange clamp structure to assemble the split sand cylinder and valve head of sand filters. The specific installation process is as follows: First, the groove of the special flange clamp must be precisely engaged with the connection port between the valve head and the sand cylinder body, ensuring that the connection surfaces of the flange clamp, valve head, and cylinder body are completely aligned. Then, the appropriate screws and nuts are installed into the pre-set screw holes on both sides of the flange clamp, and the nuts are gradually tightened with tools. During this process, the flange clamp gradually contracts under the tightening force. With the help of the tapered structure of its groove, the contraction force is transmitted to the O-ring at the connection point. By compressing the O-ring, a seal is achieved between the valve head and the cylinder body, and the overall assembly of the sand filter is finally completed. This installation method is the mainstream technical solution for connecting the split sand cylinder of sand filters.

[0003] However, the aforementioned flange clamp installation structure has significant drawbacks in practical applications, specifically: First, the installation process is complex and has a high operational threshold. The entire process requires sequentially completing multiple steps, such as aligning and clamping the flange clamps, assembling the screws and nuts, and tightening them point by point. For new users unfamiliar with sand filters, it is difficult to quickly grasp the key points of operation, which not only prolongs the installation time but also easily leads to installation failure due to omissions in steps or positional deviations. Second, the sealing reliability is poor, and leakage problems are prone to occur. The sealing effect of this structure depends entirely on the tightness of the screws and nuts. If there is insufficient tightening force, uneven force, or improper tightening of the nuts during operation, leakage will occur. Loosening or other issues can lead to insufficient pressure from the flange clamp on the O-ring, preventing an effective seal and causing water leakage during sand filter operation. This affects the normal function of filtration and may even cause water pollution to the surrounding environment. Thirdly, it increases product and logistics costs. The flange clamp structure requires additional flange clamps, multiple sets of screws and nuts, increasing the variety of parts and manufacturing costs. At the same time, the size of the flange clamp increases the overall size of the split sand filter, making it impossible to effectively reduce the packaging volume during product packaging, indirectly increasing the consumption of packaging materials and transportation costs during logistics and transportation.
