Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of membrane shell, specifically relates to a high pressure resistant membrane shell. BACKGROUND

[0002] In the field of water treatment and membrane separation technology, membrane shell as the key component of bearing membrane element, its pressure resistance is important to the stability and safety of the whole system. With the development of membrane separation technology, higher requirements are put forward for the pressure resistance of membrane shell, and because the length of membrane shell is generally longer, it is not easy to ensure horizontal installation during installation, and there will be slight inclination, which will cause the internal water pressure of one end of the membrane shell to be higher than that of the other end, increasing the compression requirement of both ends. SUMMARY

[0003] The main purpose of the utility model is to provide a high pressure resistant membrane shell for improving the compression resistance of the membrane shell and reducing the possibility of damage to the membrane shell.

[0004] To achieve the above purpose, the utility model provides a high pressure resistant membrane shell, which comprises a membrane shell body, water inlet ports and water outlet ports are arranged at both ends of the membrane shell body respectively, a glass steel thickening layer is arranged on the outer wall of the membrane shell body, and the glass steel thickening layer is arranged around the side wall of the membrane shell body.

[0005] The high pressure resistant membrane shell provided by the utility model has water inlet ports and water outlet ports arranged at both ends of the membrane shell body respectively for guiding fluid to enter and exit the membrane shell, and a glass steel thickening layer is arranged on the outer wall of the membrane shell body, which is arranged around the side wall of the membrane shell body, thereby enhancing the structural strength and pressure resistance of the membrane shell, enabling the side wall of the membrane shell to withstand higher internal pressure when the membrane shell is inclined, improving the compression resistance of the membrane shell, and reducing the possibility of damage to the membrane shell.

[0006] In a possible implementation manner, the cross section of the glass steel thickening layer is an arc plate, and the curvature of the glass steel thickening layer is 180°. The glass steel thickening layer arranged in an arc shape reduces the overall mass of the membrane shell and reduces the cost, and in use, the side wall provided with the glass steel thickening layer only needs to be arranged downward, because the inner diameter of the membrane shell is large, so the upper side wall of the membrane shell without the glass steel thickening layer can also withstand pressure.

[0007] In a possible implementation manner, the water inlet ports and the water outlet ports are in the same direction, and the glass steel thickening layer is arranged on the side opposite to the water inlet ports and the water outlet ports. The water inlet ports and the water outlet ports are in the same direction, and the glass steel thickening layer is arranged on the side opposite to the ports. This layout helps to balance the pressure distribution inside the membrane shell, that is, the water inlet ports and the water outlet ports are arranged in the upward direction, and the glass steel thickening layer is arranged on the lower side.

[0008] In a possible implementation, the membrane shell body is provided with a port protection layer on the side wall at both ends, and the water inlet port and the water outlet port pass through the port protection layer.

[0009] In a possible implementation, the port protection layer is made of glass fiber reinforced plastic. The membrane shell body is provided with a port protection layer on the side wall at both ends, and the port protection layer is made of glass fiber reinforced plastic, thereby providing additional protection and support for the water inlet port and the water outlet port.
