A using method of a biodiesel pretreatment device comprises the following specific steps:

the method comprises the following steps: the method comprises the following steps of enabling a biodiesel raw material to be filtered to enter the inside of a connecting pipe from a feed hopper and then fall into a discharge port from the connecting pipe, closing an electromagnetic valve, enabling the raw material to enter the inside of a circulating plate from the inside of the discharge port and further fall into the upper parts of filter screen plates on two sides from two ends of the circulating plate; the liquid raw material is filtered by a plurality of filter screen plates from top to bottom and finally falls into the receiving trough;

step two: a large amount of impurities are left on the upper part of the filter screen plate after filtration, the motor is started to drive the bottom plate and the filter screen plate to incline to one side, meanwhile, the motor is driven to drive the roller to rotate in the sliding groove, and the roller drives the cleaning plate to move on the upper part of the filter screen plate; a shovel plate at one end of the bottom of the cleaning plate shovels impurities on the upper part of the filter screen plate; when the shovel plate works, the adjusting bolt is screwed to move up and down in the middle of the mounting plate, and the distance between the shovel plate and the filter screen plate is changed;

step three: when the raw materials in preparation need to be evaporated and dried, the electromagnetic valve is opened, the elastic plate is pulled out from the interior of the shovel plate, the winding shaft rotates when the elastic plate is pulled, and the elastic plate is separated from the exterior of the winding shaft; pulling the elastic plate to move towards the other end of the filter screen plate until the elastic plate covers the upper part of the filter screen plate; pressing the baffle plate downwards, moving downwards at one end of the transverse plate, enabling the baffle plate to be abutted against the side wall of one end of the filter screen plate, and stably laying the elastic plate on the upper part of the filter screen plate; the liquid raw materials to be evaporated and dried enter the discharge port from the feed hopper, then flow into the dispersing pipeline from the shunt pipe, flow into the hoses on the two sides from the dispersing pipeline, and finally flow down to the upper part of the elastic plate from the discharge pipe;

step four: after evaporation drying is finished, the motor drives the bottom plate to rotate, the bottom plate inclines to one side, the baffle plate is pulled upwards, the elastic plate contracts, the return spring drives the winding shaft to rotate, the elastic plate is wound outside the winding shaft, the upper part of the elastic plate is in contact with the bottom end of the scraper plate when the elastic plate contracts, the scraper plate scrapes off substances left by evaporation outside the elastic plate, and the scraped substances fall to one end;

step five: when the bottom plate is replaced, the positioning bolt at one end is unscrewed, the bottom plate is pushed towards one end, the telescopic rod at one end enters the sleeve, the limiting block at the other end is separated from the inserting hole, and then the bottom plate is detached from the middle body of the box body; during the installation, with the telescopic link extrusion shrink at both ends in telescopic inside, put between the baffle at the lateral wall of box and middle part, move the inside of spliced eye until the spacing block at both ends, damping spring promotes the telescopic link and removes, pushes the inside of spliced eye with the stopper, screws up positioning bolt, and the inside at the box is installed to the bottom plate.

The invention has the beneficial effects that:

1. through the installation of a plurality of filter screen boards in the inside of box for the biodiesel raw materials that will wait to filter fall into behind the upper portion of the filter screen board of both sides from the both ends of circulation board. The liquid raw material is filtered by a plurality of filter screen plates from top to bottom and finally falls into the receiving trough. The raw materials are filtered more efficiently and more sufficiently by the multiple layers of filter screen plates with different thicknesses.

2.

According to the baffle of pressing down, the baffle can with the one end lateral wall butt of filter screen board, the elastic plate can be stable lay on the upper portion of filter screen board, be difficult for the shrink to drop, and the backing plate of one end can support the elastic plate in the bottom for the elastic plate can keep the horizontally state, and the liquid raw materials of treating the evaporation can be deposited on upper portion, and the raw materials is difficult for the slope to flow down, can be stable by the evaporation stoving. The liquid raw material to be evaporated and dried enters the discharge port from the feed hopper and finally falls on the upper part of the elastic plate through the discharge pipe. The flowing direction of the raw materials can be controlled by opening and closing the electromagnetic valve, so that the raw materials can be controlled conveniently and quickly. The inside of box can filter, also can evaporate the stoving, can accord with multiple user demand. The evaporation efficiency is high, and the raw materials on the elastic plate are less, can expand a plurality of elastic plate in the box inside, the evaporation that can be quick.

4. Through connecting the scraper blade at shovel board one end for after the evaporation is dried, the motor can drive the bottom plate and rotate, to one side slope. Upwards pulling the baffle, the elastic plate shrink, return spring drives the winding axle and rotates, and the elastic plate winding is in the outside of winding axle, and the bottom contact of upper portion and scraper blade when the shrink of elastic plate, scraper blade strike off the remaining material of elastic plate outside evaporation, and the material after striking off drops to one end, conveniently collects. The matter falling on the upper part of the filter screen plate is shoveled by a shovel plate. The substances obtained by drying and evaporation can be fully collected and are not easy to spill.

5. When the bottom plate is used and needs to be replaced, the positioning bolt at one end is unscrewed, the bottom plate is pushed towards one end, the telescopic rod at one end enters the sleeve, the limiting block at the other end is separated from the insertion hole, and then the bottom plate can be conveniently detached from the box body. The filter screen plate and the cleaning plate on the upper portion of the bottom plate can be replaced together with the bottom plate in a free replacement mode, replacement is convenient and fast, the bottom plates and the filter screen plates in different quantities can be installed, and different work and use requirements can be met.
