Detailed Description
In order to more clearly describe the technical content of the present invention, the following further description is given with reference to specific embodiments.
In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.
In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
As shown in fig. 1, for the specific embodiment of plate and frame filter press for high ammonia nitrogen sewage treatment, wherein, set up on this plate and frame filter press and prevent odor diffusion equipment, prevent odor diffusion equipment including the several flowing back hose 3 that is located 1 one side of plate and frame filter press main part and be located the two way water pipes at 1 top of plate and frame filter press main part, the water pipe on set up several looks spaced nozzle 2, flowing back hose 3 be used for collecting the discharge filtrating when the filter-pressing operation, nozzle 2 be used for unloading the cake operation at the arm-tie and spray water to the plate and frame.
In many cases of ammonia nitrogen wastewater treatment, filter cake removal by pulling plates is usually accomplished by workers wearing gas masks and gloves, and the ventilation of a factory needs to be maintained. The utility model discloses a prevent odor diffusion device, through the mode that the nozzle sprayed water, effectively eliminate the smell, improve workman operational environment, it is economical convenient, effectual, follow-up filtrating is collected conveniently.
As shown in fig. 1, the odor diffusion preventing device comprises a liquid collecting pipe 4, and one end of the liquid collecting pipe 4 is connected with the plurality of liquid discharging hoses 3. In addition, the liquid collecting pipe 4 is provided with a pressure alarm 5.
The utility model discloses a prevent odor diffusion device, directly use the flowing back hose to be connected with the collector tube, it can be stronger to practice the nature of operating to it is more convenient to change the hose. In addition, the pressure alarm is arranged on the liquid collecting pipe, and only the pressure alarm needs to be arranged, and the hose can be replaced when the pressure is higher than a set value.
