Large filter with lifting device

Abstract

The invention relates to a large filter with a lifting device. The large filter comprises a shell, a filter basket, a feeding pipe, a lower flange, a flat cover flange, a discharging pipe and a blow-off pipe. The large filter is characterized by further comprising a fixed connection plate, a screw rod, a sleeve, a hand wheel, an L-shaped rotating rod, an annular plate, a sleeve pipe and a bearing plate, wherein the fixed connection plate is arranged on the flat cover flange, one end of the screw rod is fixed to the fixed connection plate, the screw rod is sleeved with the sleeve, the hand wheel is arranged at the portion, on the upper side of the sleeve, of the screw rod, one end of the bearing plate is connected to the side wall of the shell, the other end of the bearing plate is fixedly connected with the outer side wall of the sleeve pipe, one end of the L-shaped rotating rod is fixedly connected with the outer side wall of the sleeve, and the other end of the L-shaped rotating rod is provided with the annular plate and inserted into the sleeve pipe. The large filter has the advantages of being simple in structure and facilitating internal overhauling and cleaning of the filter basket.

Description

technical field [0001] The invention relates to a large filter, in particular to a large filter with a lifting device. Background technique [0002] With the development of industry, filters are widely used in various fields, mainly used to filter gases, liquids, oils, etc. containing impurities, covering chemical, textile, pharmaceutical, metallurgy, food and other fields. There are many types and structures of filters, but they have one thing in common: small size and light weight. As the filtration capacity required by various industries is different, the filtration capacity of small filters can no longer meet the filtration requirements of related fields, especially under the rigid demand of some large chemical companies, manufacturing large filters is the market trend. The existing large-scale filter includes a shell, a filter basket, a feed pipe, a lower flange, a flat cover flange, a discharge pipe, and a sewage pipe; the filter basket is arranged in the shell; the s...

As the filtration capacity required by various industries is different, the filtration capacity of small filters can no longer meet the filtration requirements of related fields, especially under the rigid demand of some large chemical companies, manufacturing large filters is the market trend. The existing large-scale filter includes a shell, a filter basket, a feed pipe, a lower flange, a flat cover flange, a discharge pipe, and a sewage pipe; the filter basket is arranged in the shell; the sewage pipe is arranged at the bottom of the shell, and the feed pipe The pipe and the discharge pipe are respectively arranged on the side wall of the casing, the lower flange is arranged at the upper port of the casing, and the casing is arranged on the lower flange; due to the heavy weight of the large filter, especially the flat cover method on the top of the filter Lan, some filters operate at relatively high pressure, and the designed flat cover flange is very heavy, which makes it inconvenient to check the interior of large filters and clean the filter basket
