Detailed Description
The inventor finds that the centrifugal slurry pump or the diaphragm pump is used for feeding the filter press independently in the working practice and has certain limitation. The centrifugal slurry pump features high power, high flow rate and constant rotation speed of its impeller. At the initial feeding stage of the filter press, namely when a filter chamber of the filter press is in a cavity stage, the slurry pump operates under the working conditions of low lift (namely low pressure) and large flow, and the advantages and the efficiency of the slurry pump are fully exerted; in the pressure dehydration stage after the material is filled in the filter chamber of the filter press, the flow rate of the material entering the filter press is greatly reduced, and at the moment, the slurry pump is required to work under the working condition of low flow and high lift, so that on one hand, the impeller of the overflowing part of the slurry pump rotating at high speed and the material in the pump shell form severe friction due to high-speed relative motion, the impeller is quickly abraded, the service life of the impeller is reduced, and the production cost is increased; on the other hand, the slurry pump runs under a high-lift working condition for a long time, so that the shaft sealing of the slurry pump is easy to lose efficacy and slurry is easy to leak, and the working environment is seriously polluted.
The hydraulic drive type diaphragm pump has the characteristics of small installed power, small flow of the pump, constant power drive, and capability of automatically adjusting the flow and the output pressure without causing any adverse damage to equipment. In the initial stage of feeding the filter press, the diaphragm pump feeds the filter press at the maximum flow and low pressure, but the rated flow is small, so that the feeding time of the filter press is long, and the overall production efficiency is low. However, in the pressurizing and dehydrating stage at the later stage of feeding, the material pushing disc of the diaphragm pump can push the material into the filter press at a very low moving speed and a maximum pushing force (namely, a small flow and a large pressure), so that the pressurizing and dehydrating of the material are realized. And the overflowing part pushing disc of the diaphragm pump and the material are pushed to move slowly by the front surface, almost no relative motion exists, and the problem of accelerated abrasion of the pressure disc does not exist.
In order to overcome the above-mentioned disadvantages of the two conventional processes of separately configuring the feeding equipment, the present inventors have proposed a new method and system for feeding a filter press, in which a centrifugal slurry pump and a hydraulically driven diaphragm pump are used in parallel to feed the filter press, as shown in fig. 3, an incoming material is introduced into an agitation tank 302, and a slurry pump 301 and a diaphragm pump 303 are arranged in parallel to pump the material from the agitation tank 302 to a filter press 304. At the initial feeding stage of the filter press, the slurry pump 301 alone or together with the diaphragm pump 303 feeds the filter press with a large flow and a low pressure, and at the pressurizing and dehydrating stage at the later feeding stage of the filter press, the operation of the slurry pump 301 is stopped, and the diaphragm pump 303 feeds the filter press 304 with a small flow and a large pressure, so that the pressurizing and dehydrating of the materials are realized.
Obviously, the advantages of the feeding method of a filter press according to the utility model include:
the rapid feeding of the filter press is ensured, namely, the rapid abrasion of the impeller of the slurry pump is not caused under the condition of ensuring the higher overall production efficiency of the filter press, the failure leakage tendency of the shaft seal of the slurry pump is greatly reduced, the production cost is reduced, the operation effect of the feeding equipment is improved, and the pollution of the slurry pump to the operation environment due to the leakage of slurry is reduced.
