In order to solve the technical problems, the technical scheme of the utility model is as follows: the utility model provides a take fume chamber of dust filter, includes the experiment cabinet body and establishes the locker body in experiment cabinet body below, the experiment cabinet body includes laboratory bench, the backplate that is located the back, is located positive glass door and the curb plate that is located both sides, the place ahead of back is equipped with the guide plate, be equipped with the clearance between guide plate and the backplate; still include dust filter, dust filter includes a plurality of air exhauster that establish between backplate and guide plate, establish the filter core in the locker body and establish the dust collector in the filter core below, the air intake that corresponds air exhauster department on the guide plate, the output of air exhauster is connected with the input of filter core through lower blast pipe, the output of filter core is connected with last blast pipe. The principle of the utility model is as follows: dust generated in the experimental process can be sucked by the exhaust fan, the dust downwards enters the filter element along with the action of air flow and self gravity, the dust can be filtered by the filter element, the blocked dust is finally attached to the filter element or falls down to the dust collector below to be collected, the filtered clean air is upwards discharged through the upper exhaust pipe, and the filtered dust cannot return to the workbench, so that the cleanliness of the workbench is ensured.
As an improvement, a plurality of air inlets distributed in a matrix are arranged in the middle of the guide plate.
As an improvement, the filter element is a drawer type filter element.
As an improvement, a funnel-shaped dust collecting pipe is arranged between the filter element and the dust collector.
As an improvement, the upper exhaust pipe is arranged between the back plate and the guide plate, the lower end of the upper exhaust pipe stretches into the storage cabinet body, and the upper end of the upper exhaust pipe stretches out of the top of the experiment cabinet body.
As an improvement, the filter element is horizontally arranged, the upper end face of the filter element is an input end, and the lower end face of the filter element is an output end.
As an improvement, the filter element is horizontally arranged, the lower end face of the filter element is an input end, and the upper end face of the filter element is an output end.
Compared with the prior art, the utility model has the beneficial effects that:
the filter element is arranged in the storage cabinet, so that the space is not occupied, and dust can easily enter the filter element downwards for filtration and collection under the action of air flow and self gravity.
Drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a side view of the present utility model.
Description of the embodiments
The utility model is further described below with reference to the drawings.
As shown in fig. 1 and 2, a fume hood with dust filter includes an experiment cabinet body 1, a storage cabinet body 2 arranged below the experiment cabinet body 1, and the dust filter. The experiment cabinet body 1 comprises an experiment table, a back plate positioned on the back surface, a glass door positioned on the front surface and side plates positioned on two sides, wherein a guide plate 9 is arranged in front of the back surface, and a gap is formed between the guide plate 9 and the back plate. The dust filter comprises a plurality of exhaust fans 8 arranged between a back plate and a guide plate 9, a filter element 3 arranged in the storage cabinet body 2 and a dust collector 5 arranged below the filter element 3; an air inlet is formed in the guide plate 9, which corresponds to the exhaust fan 8, a plurality of air inlets distributed in a matrix are formed in the middle of the guide plate 9, and a plurality of exhaust fans 8 generate strong negative pressure in the experimental cabinet body so as to suck dust; the output end of each exhaust fan 8 is connected with the input end of the filter element 3 through a lower exhaust pipe 6, and the output ends of the exhaust fans 8 are converged on one lower exhaust pipe 6; the output of filter core 3 is connected with last blast pipe 7, go up blast pipe 7 and establish between backplate and guide plate 9, go up the lower extreme of blast pipe 7 and stretch into in the locker body 2, the top of experimental cabinet body 1 is stretched out to the upper end of going up blast pipe 7.
