Multi-pipe type centrifugal solid-liquid separation machine

Abstract

The invention discloses a multi-pipe type centrifugal solid-liquid separation machine. The multi-pipe type centrifugal solid-liquid separation machine is characterized by comprising a stationary feed inlet, an upper conical shell, a main shell, a skirt base, a movable feed inlet, a revolving drum assembly, a transmission assembly, a top bearing assembly, filter cartridges, a liquid outlet, a main motor, a key, a main belt wheel, a belt and a slave belt wheel, and further comprising ratchet wheels, driving pawls, stop pawls, driving handles, hydraulic cylinders, branch oil pipes, a main oil pipe assembly, a movable-stationary connector, a main oil pipe, a hydraulic station and a control cabinet; the exterior is sequentially connected with the stationary feed inlet, the upper conical shell, the main shell and the skirt base from top to bottom, and the movable feed inlet, the revolving drum assembly and the transmission assembly are sequentially and coaxially assembled inside; the six to eight filter cartridges are evenly installed in the circumferential direction of the revolving drum assembly, the angle between the axes of the filter cartridges and the central axis of the revolving drum assembly is three to seven degrees, and a ratchet wheel mechanism and a hydraulic system are matched to drive the filter cartridges to rotate; and the control cabinet is connected with the main motor and the hydraulic station through cables. The problems that meshes of filter screens are prone to blockage and filter production is not continuous are solved, and the multi-pipe type centrifugal solid-liquid separation machine is simple in structure and convenient to maintain.

Description

Technical field: [0001] The invention relates to a multi-tube centrifugal solid-liquid separator, in particular to a multi-tube centrifugal solid-liquid separator with self-cleaning function and continuous filtration production. Background technique: [0002] Filtration technology is widely used in petroleum, chemical industry, mining, medicine, food and other fields. Its main characteristics are: the material flows to the filter medium, the liquid passes through the filter medium, and the larger solid particles are blocked on the side of the filter medium to form a filter cake. The filter pores of the media may be blocked and the filter resistance increases. When the filter cake accumulates to a certain thickness, the filter holes are completely blocked, and the filter resistance increases significantly, so the filter medium needs to be cleaned, and the filter production is often carried out intermittently. [0003] I have previously applied for a patent "A Forced Unloadin...

Problems solved by technology

However, according to the patent ZL201310098406.3, there are still deficiencies in the driving mode of the forced discharge self-cleaning centrifugal dryer, the disassembly method of the filter cartridge, and the structure of the static feed port, dynamic feed port, top bearing, filter cartridge bearing and other components. ; and there is no control box, it is difficult to control the speed of revolution and rotation, especially the problems of unsmooth feeding, difficult maintenance of filter cartridge bearings, and short service life of the self-rotation drive belt due to the influence of the revolution of the filter cartridge, which limits the use of patent ZL201310098406.3 The wide application of the forced unloading self-cleaning centrifugal dryer provided
