Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figures 1 to 4, this rotational moulding drying tunnel comprises housing 1, combustor 2 and gas cylinder 3.
There is in housing 1 volute chamber 1a, the air intake passage 1b be all connected with volute chamber 1a and air-out passage 1c.Be provided with draught fan impeller 4 in volute chamber 1a, the rotating shaft 4a of draught fan impeller 4 passes housing 1.
Combustor 2 is fixed on an end wall of air intake passage 1b, and the air inlet 1b1 of air intake passage 1b opens on the sidewall of air intake passage 1b; The flame flow direction of combustor 2 ejection is identical with air-flow direction in air intake passage 1b thus; And then the fuel making combustor 2 spray can burn efficiently.
Gas cylinder 3 is positioned at air intake passage 1b, and gas cylinder 3 is fixedly connected with housing 1.The bocca 2a of combustor 2 and the Single port of gas cylinder 3 can make bocca 2a be in connected state with the Single port of gas cylinder 3 by one or the control piece 5 that is in cut-off state is connected, and the another port of gas cylinder 3 is towards volute chamber 1a.The flame flow that gas cylinder 3 avoids air intake passage 1b airflow influence combustor 2 to spray, the sidewall of simultaneously gas cylinder 3 has several apertures 3a, and aperture 3a and air inlet 1b1 is oppositely arranged; Make more air enter in gas cylinder 3, improve the fuel-efficient burning that combustor 2 sprays further.
The air inlet 1b1 of air intake passage 1b is strip and vertically arranges, gas cylinder 3 is also vertically arranged, the air inlet 1b1 lower edge of air intake passage 1b is not crossed in the lower surface of gas cylinder 3, namely have spacing h between the lower surface of gas cylinder 3 and the air inlet 1b1 lower edge of air intake passage 1b, this structure enters volute chamber 1a after the air entered from the air inlet 1b1 of air intake passage 1b is fully mixed with the thermal current sprayed from gas cylinder 3 again; And then ensure that the gas flow temperature blown out from air-out passage 1c is balanced.Control piece 5 is gate valve or butterfly valve or ball valve.
The air outlet 1c1 place of air-out passage 1c is provided with the some wind deflectors be arranged in parallel 6, and wind deflector 6 and housing 1 are hinged, and according to actual conditions, manual toggle wind deflector 6 can be adopted to swing, and motor also can be adopted to drive wind deflector 6 to swing; In a word, by the water conservancy diversion of wind deflector 6, thermal current is blown to desired position place, and then utilize this rotational moulding drying tunnel to heat Plastic Rolling Molds, mould is heated evenly, and then makes dark chamber class plastic products can straight forming.
As shown in Figures 1 to 4, Plastic Rolling Molds heater comprises baking oven 7 and rotational moulding drying tunnel.
Baking oven 7 is cylindrical, and baking oven 7 is put upside down on the ground.According to actual conditions, the cross section of baking oven 7 also can adopt square, hexagon, octagonal or fan-shaped.
Rotational moulding drying tunnel is positioned at the side of baking oven 7, and a side of rotational moulding drying tunnel middle shell and a side of baking oven middle shell are affixed to be leaned on, and reduces baking oven 7 and rotational moulding drying tunnel and extraneous contact area, and then improves the efficiency of heating surface, reduces energy resource consumption.The air inlet 1b1 of air intake passage 1b is all connected with the baking oven 7 of baking oven 7 with the air outlet 1c1 of air-out passage 1c.The air inlet 1b1 of air intake passage 1b and the air outlet 1c1 of air-out passage 1c is all positioned on a side of above-mentioned rotational moulding drying tunnel middle shell; Air outlet 1c1 is positioned at the below of air inlet 1b1; Make full use of the characteristic that hot gas upwards flows naturally, Plastic Rolling Molds is heated evenly, improve the efficiency of heating surface further, reduce energy resource consumption.
Ground is fixed with axle bed 8, the rotating shaft 4a of draught fan impeller 4 is positioned on axle bed 8.The rotating shaft 4a of draught fan impeller 4 is connected by belt with the blower motor 9 fixed on the ground.
Housing 1 is fixed with the actuator 10 that control piece 5 can be driven to move; Control element in control element in actuator 10 and blower motor 9 is all electrically connected with control circuit.Control circuit is single-chip microcomputer or PLC; Actuator 10 is cylinder or motor, and the control element in cylinder is magnetic valve, and the control element of motor is relay; Control element in blower motor 9 is also relay.When blower motor 9 is in stopped status, control circuit controls actuator 10 makes the Single port of bocca 2a and gas cylinder 3 be in cut-off state; When blower motor 9 is in running status, control circuit controls actuator 10 makes the Single port of bocca 2a and gas cylinder 3 be in connected state.This structure avoids the fuel leaked from the bocca 2a of combustor 2 enter volute chamber 1a and enter in baking oven 7 effectively, and then thoroughly stops fuel leakage and cause the accident of device damage or casualties.
