Delivery pump orifice electric heating heat-preservation system

The utility model is suitable for a heating heat-preservation system, and particularly relates to a delivery pump orifice electric heating heat-preservation system. The delivery pump orifice electric heating heat-preservation system comprises a plurality of delivery pumps, two power source main junction boxes, sixteen electronic-control distribution boxes, a plurality of pore plates and a plurality of electric heating films corresponding to the pore plates in shape, size and position, wherein the output end of each power source main junction box is connected with the input ends of eight electronic-control distribution boxes in parallel, and the power source main junction boxes control disconnection or connection of the electronic-control distribution boxes and distribute voltage for the electronic-control distribution boxes; the two sides of each delivery pump are communicated with the multiple pore plates, the pore plates are correspondingly provided with the electric heating films, and each electronic-control distribution box is connected with the multiple electric heating films on the corresponding delivery pump in parallel and transmits transformed voltage for the electric heating films. Through the design of the electric heating films and an automatic monitoring circuit, the phenomena of freezing and blockage of the delivery pumps within the ash discharge period are resolved, the delivery pumps are clear at a glance in the routing inspection process, and safe and reliable ash discharging of the delivery pumps is guaranteed.
