Drawings
Fig. 1 is a schematic structural diagram of a filter housing structure of a water treatment filter element of the present invention.
In the figure: 1. an upper section housing; 2. a lower housing; 3. an upper section flange; 4. a lower section flange; 5. fastening a bolt; 6. an annular seal ring; 7. a first limit ring; 8. a second stop collar; 9. and a central limit plate.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, a filter shell structure of a water treatment filter element comprises an upper section shell 1 and a lower section shell 2, wherein the upper section shell 1 is connected with an upper section flange 3, the lower section shell 2 is connected with a lower section flange 4, the upper section flange 3 is connected with the lower section flange 4 through a fastening bolt 5, an annular sealing ring 6 is arranged between the upper section flange 3 and the lower section flange 4, and two sides of the annular sealing ring 6 are respectively provided with a first limiting ring 7 and a second limiting ring 8.
Preferably, a central limiting plate 9 which is inclined downwards is arranged on the inner wall of the upper-section shell 1.
Preferably, the thickness of the central limiting plate 9 is less than 4mm.
Preferably, the first stop collar 7 and the second stop collar 8 have the same thickness.
The filter shell structure of the water treatment filter element in the scheme needs to fundamentally block the leakage in order to avoid the situation, and an isolation mode can be adopted. The flange that this device can effectively solve in the wet casing seals and prevents that the lime set from corroding and lead to revealing the scheduling problem. The device can also effectively protect the structural integrity of the shell, and can also effectively protect the outer cylinder from being corroded by smoke in the application of sleeve shells and the like. The device is simple and convenient to install, can greatly shorten the field installation time, and saves the installation fund for the construction unit.
The upper section flange 3 is connected with the upper section shell 1, and the upper section flange 3 limits the terminal displacement of the upper section flange 3; the lower section flange 4 is connected with the lower section shell 2, and the lower section flange 4 limits the terminal displacement of the lower section flange 4; an annular gap is formed between the upper section flange 3 and the lower section flange 4, and an annular sealing ring 6 is filled in the sealing ring during sealing; the annular sealing ring 6 is positioned against a first stop collar 7 and a second stop collar 8. The upper and lower casings 1, 2 are held down by a series of fastening bolts 5. The central limit plate 9 is welded with the inside of the upper section shell 1.
The working principle is as follows: during the use, earlier with upper segment casing 1 and hypomere casing 2 be close to the certain distance, place annular seal 6 in the annular gap that upper segment flange 3 and hypomere flange 4 formed, then put down upper segment casing 1, utilize its self weight to press annular seal 6 full annular gap, utilize fastening bolt 5 to fasten upper segment flange 3 and hypomere flange 4 at last, realize holistic sealed effect. Simultaneously, the center limiting plate 9 can be with the filter core location to the center of casing guarantee the concentricity, can make the filth on filter core surface keep away from the flange seal face in addition, realizes the dual protection measure.
The annular sealing ring 6 is woven by specially-made high-molecular polymer fibers. The material is formed by solid weaving, has flexibility and adjustability, and can be completely matched with the upper section flange 3 and the lower section flange 4. Has good corrosion resistance, self-lubricating property and anti-sticking property. The temperature resistance range is-100 to 200 ℃, the PH application range is 0 to 14, and the adhesive tape is completely applied to the use occasion conditions.
The first and the second limit rings, the lower section flange 4 and the upper section flange 3 can be partially or completely cancelled according to the diameter of the used shell inner cylinder. The central limiting plate 9 is made of a material with corrosion resistance equal to or higher than that of the upper end section shell inner wall, and the thickness of the central limiting plate 9 is generally not more than 4mm. When the water baffle is connected with the upper section shell 1, the interior of the upper section shell 1 cannot be damaged, and appropriate surface treatment is required after the connection.
The upper section flange 3 and the lower section flange 4 are staggered to form a labyrinth form, so that gas leakage can be effectively prevented. The selected annular sealing ring 6 is made of a high acid and alkali resistant material, so that acid liquor corrosion under normal working conditions can be effectively prevented. The flange joint is sealed well, reduces the cost of later stage reworking maintenance. The structure is well attached to the device, and the risk of leakage at the flange is reduced. The corrosion resistance of the central limiting plate 9 is equal to or superior to that of the upper shell 1, so that the corrosion resistance of the whole shell can be ensured.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
