Abstract

The invention relates to a multi-bag type filter which comprises an upper box, a lower box, filter bags and a deashing mechanism, wherein the bottom end of the upper box is communicated with the upper end of the lower box, the filter bags are arranged in the upper box, an arbitrary filter bag is a double-layer filter bag, the lower ends of the filter bags are connected with the bottom end of the upper box, the deashing mechanism comprises a driving arm, a sliding block and a guide rod, wherein the guide rod is fixedly arranged between the top end and the bottom end of the upper box along the axial center of the upper box, the sliding block is sleeved on the guide rod and connected with the upper ends of the filter bags, and the upper end of the driving arm is connected with the sliding block; the lower end of the driving arm is connected with the upper end of a rocking rod through a pin shaft, the lower end of the rocking rod is connected with a driving shaft, and the driving shaft is connected with the bottom end of the upper box through a bearing. The double-layer filter bags are arranged in the filter and are compressed by using the mechanical deashing mechanism, therefore, the specific surface area of the filter bags is increased, the efficiency of the filter is improved, and small particles left between the inner-layer filter bag and the outer-layer filter bag can be conveniently cleaned.

Description

Technical field: [0001] The invention relates to the field of machinery, in particular to automobiles, in particular to exhaust gas discharge devices for automobiles, in particular to a multi-bag filter. Background technique: [0002] Exhaust from car engines contains particulates that need to be filtered before they can be released into the atmosphere. In the prior art, a cylindrical filter is used to treat automobile exhaust gas. The filter bag in the cylindrical filter is a single-layer filter bag. As the running time increases, the particles captured by the filter bag increase, the filtration efficiency decreases, and the discharge Gas back pressure increases, affecting engine performance and increasing engine fuel consumption. Invention content: [0003] The object of the present invention is to provide a multi-bag filter, which solves the technical problem of low filtration efficiency of single-layer filter bags in cylindrical filters in the prior art. [0004] The...
