Problems solved by technology

[0002] The bakers of the prior art mainly have the following disadvantages: 1. There are gaps around the flame-injecting burner, which may easily cause fire and affect the baking efficiency of the mold; 2. During the baking process, the flow ratio of natural gas and air cannot be controlled. On the one hand, it leads to incomplete combustion, on the other hand, it also affects the quality of the baked bag

Embodiment 1

[0042] Step 1. Ignition process

[0043] Open the natural gas on-off valve 12 to regulate the flow of natural gas through the natural gas flow regulating valve 13;

[0044] Open the combustion-supporting air switch valve 14, and adjust the flow rate of the combustion-supporting air through the combustion-supporting air flow regulating valve 15;

[0045] Turn on the ignition button on the burner 7, the ignition is successful, then turn on the combustion-supporting fan 11, and start the proportional control valve 16 to ensure that the flow rate of the mixed gas is 15m 3 / h: Adjust the ratio of natural gas and combustion-supporting air through the combustion of the burner 7, so that the ratio of natural gas and combustion-supporting air is suitable to achieve the best combustion effect;

[0046] If ignition fails, close the natural gas on-off valve 12 and the combustion-supporting air switch-off valve 14 immediately, the residual gas inside the natural gas pipeline 9 and the com...

Embodiment 2

[0052] Step 1. Ignition process

[0053] Open the natural gas on-off valve 12 to regulate the flow of natural gas through the natural gas flow regulating valve 13;

[0054] Open the combustion-supporting air switch valve 14, and adjust the flow rate of the combustion-supporting air through the combustion-supporting air flow regulating valve 15;

[0055]Turn on the ignition button on the burner 7, the ignition is successful, then turn on the combustion-supporting fan 11, and start the proportional control valve 16 to ensure that the flow rate of the mixed gas is 17m 3 / h: Adjust the ratio of natural gas and combustion-supporting air through the combustion of the burner 7, so that the ratio of natural gas and combustion-supporting air is suitable to achieve the best combustion effect;

[0056] If the ignition fails, immediately close the natural gas on-off valve 12 and the combustion-supporting air on-off valve 14, and the residual gas inside the natural gas pipeline 9 and the ...

Embodiment 3

[0059] Step 1. Ignition process

[0060] Open the natural gas on-off valve 12 to regulate the flow of natural gas through the natural gas flow regulating valve 13;

[0061] Open the combustion-supporting air switch valve 14, and adjust the flow rate of the combustion-supporting air through the combustion-supporting air flow regulating valve 15;

[0062] Turn on the ignition button on the burner 7, the ignition is successful, then turn on the combustion-supporting fan 11, and start the proportional control valve 16 to ensure that the flow rate of the mixed gas is 20m 3 / h: Adjust the ratio of natural gas and combustion-supporting air through the combustion of the burner 7, so that the ratio of natural gas and combustion-supporting air is suitable to achieve the best combustion effect;

[0063] If the ignition fails, immediately close the natural gas on-off valve 12 and the combustion-supporting air on-off valve 14, and the residual gas inside the natural gas pipeline 9 and the...

Abstract

The invention discloses a ladle dryer and a control process thereof. The ladle dryer comprises a machine frame; a lifting motor and a transfer shaft driven by the lifting motor are installed at one end of the machine frame; a fixed guide wheel and a burning sealing end cover are installed at the other end of the machine frame; the lifting motor drives the transfer shaft and transmits power to the fixed guide wheel in a chain transmission mode; the burning sealing end cover is driven by the fixed guide wheel to ascend and descend vertically; the burning sealing end cover is provided with a burner; the inlet end of the burner is connected with a hybrid gas pipeline through a connector; the hybrid gas pipeline is connected with a natural gas pipeline and a combustion air pipeline; the outlet end of the burner is provided with a burning sealing end cover. In this way, the ladle dryer and the control process thereof can sufficiently dry casting moulds, adjust the proportion of natural gas to combustion air, ensure the hybrid gas to reach the optimal value and burn sufficiently, and achieve the optimal burning effect.

Description

technical field [0001] The invention relates to the technical field of foundry bakers, in particular to a baker and its control process. Background technique [0002] The baker in the prior art mainly has the following disadvantages: 1. There are gaps around the flame-injecting burner, which may easily lead to fire and affect the baking efficiency of the mold; 2. During the baking process, the flow ratio of natural gas and air cannot be controlled. On the one hand, it leads to incomplete combustion, and on the other hand, it also affects the quality of the baked bag. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a baker and its control process, which can fully dry the casting mold, adjust the ratio of natural gas and combustion air, and ensure that the mixed gas reaches the optimum value and is fully combusted to achieve the optimum Good burning effect. [0004] In order to solve the above-mentioned technica...
