When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0033] In the related art, in order to realize the intelligent control of the gas supply of the drying furnace, a pipe body is often connected between the blower and the proportional valve, and part of the air of the blower is transported to the proportional valve through the pipe body to adjust the opening of the proportional valve, thereby achieving the purpose of controlling the flow rate of the gas; but in the actual production process, the high-temperature gas in the combustion chamber is mixed with oil and water vapor, and the oil and water vapor will flow into the pipe body through the blower, and then condense in the pipe body, causing the pipe body to be blocked, causing abnormal combustion in the combustion chamber, and even causing the drying furnace to explode; the problem of pipe body blockage can only be solved by frequent maintenance or replacement of the pipe body, but this will increase the subsequent maintenance cost.

[0034] The utility model provides an accumulated liquid discharge device, a combustion device and a drying furnace, aiming to solve the problem in the prior art that a pipe connecting a blower and a proportional valve is very easy to be blocked.

[0035] See also Figure 1 In one embodiment of the utility model, the accumulated liquid discharge device 100 includes a tube body 110 and a liquid storage component 120, the tube body 110 is formed with a connecting channel 111, the connecting channel 111 has a liquid outlet 1111 and two air vents 1112, the liquid outlet 1111 is opened at the bottom of the tube body 110, the two air vents 1112 are opened at the top of the tube body 110, and the two air vents 1112 are respectively used to communicate with the blower 230 and the proportional valve 220, and the liquid storage component 120 is arranged at the liquid outlet 1111.

[0036] The technical solution of the utility model is to set a liquid outlet 1111 at the bottom of the tube body 110, so that the oil and water vapor flowing into the tube body 110 can be discharged from the tube body 110 through the liquid outlet 1111 after condensation, which can prevent the tube body 110 from being blocked, ensure the normal air flow between the blower 230 and the proportional valve 220, and reduce the occurrence of faults. Specifically, the two vents 1112 are connected to the blower 230 and the proportional valve 220 respectively. During the working process, part of the air in the blower 230 can be transported to the proportional valve 220 through the connecting channel 111 to adjust the opening of the proportional valve 220, thereby achieving the purpose of controlling the flow of gas. After the oil and water vapor flowing into the tube body 110 condenses in the tube body 110 to form an oil-water mixture, it can flow to the liquid outlet 1111 at the bottom of the tube body 110 and be discharged from the liquid outlet 1111, thereby avoiding the blockage of the tube body 110, ensuring the normal air flow between the blower 230 and the proportional valve 220, and reducing the occurrence of faults. The liquid storage assembly 120 is arranged at the liquid outlet 1111, and the oil-water mixture discharged from the liquid outlet 1111 can be collected to avoid pollution. The liquid discharge device 100 is used to connect the blower 230 and the proportional valve 220, which can avoid the blockage of the pipe body 110, ensure the normal circulation of air between the blower 230 and the proportional valve 220, and reduce the occurrence of faults. At the same time, the liquid discharge device 100 can collect the oil-water mixture in the pipe body 110 into the liquid storage assembly 120, reduce the frequency of later maintenance, and thus reduce the later maintenance cost.

[0037] See also Figure 1 In one embodiment of the utility model, the tube body 110 includes a plurality of connecting sections 120, and the plurality of connecting sections 120 are connected to form a connecting channel 111, and the connecting section 120 near the vent 1112 is located above the connecting section 120 near the liquid outlet 1111. The connecting section 120 near the vent 1112 is located above the connecting section 120 near the liquid outlet 1111, that is, the height of the connecting section 120 near the vent 1112 is higher than the height of the connecting section 120 near the liquid outlet 1111, which enables the oil and water vapor flowing into the tube body 110 to condense in the tube body 110 to form an oil-water mixture, and then flow to the liquid outlet 1111 at the bottom of the tube body 110 under the action of its own gravity and be discharged from the liquid outlet 1111.

[0038] In one embodiment of the utility model, the middle of the tube body 110 is sunken downward to form an arc-shaped tube, the liquid outlet 1111 is opened in the middle of the tube body 110, and two vents 1112 are respectively opened at both ends of the tube body 110. After the oil and water vapor flowing into the tube body 110 condenses in the tube body 110 to form an oil-water mixture, it can flow downward along the inner wall of the arc-shaped tube under the action of its own gravity, and finally flow into the liquid storage component 120 through the liquid outlet 1111. In addition, the tube body 110 can also be a V-shaped, U-shaped or other structure, and it only needs to ensure that the connecting section 120 close to the liquid outlet 1111 is located below the connecting section 120 close to the vent 1112.

The plug 122 is detachably arranged at the bottom of the liquid storage cavity. The plug 122 is used to block the bottom of the liquid storage cavity to prevent the oil-water mixture in the liquid storage cavity from flowing out. The oil and water vapor flowing into the tube body 110 condenses in the tube body 110 to form an oil-water mixture, and then flows into the liquid storage cavity through the liquid outlet 1111. The plug 122 is detachably arranged at the bottom of the liquid storage chamber, so that workers can remove the plug 122 to drain the oil-water mixture in the liquid storage chamber; during work, when the oil-water mixture in the liquid storage tube 121 is almost full, the workers can remove the plug 122 to drain the oil-water mixture in the liquid storage chamber to prevent the oil-water mixture from overflowing the liquid outlet 1111 and clogging the tube body 110.

In addition, the plug 122 can also be installed at the bottom of the liquid storage cavity by interference fit. If the plug 122 is a wooden plug that can be inserted into the liquid storage cavity and can be pulled out from the liquid storage cavity, it only needs to ensure that the plug 122 can block the bottom of the liquid storage cavity and can be removed from the bottom of the liquid storage cavity.

[0041] See also Figure 1In one embodiment of the utility model, the plug 122 forms a limiting portion 1221, and the limiting portion 1221 can abut against the bottom of the liquid storage tube 121. The limiting portion 1221 plays a limiting role, and the limiting portion 1221 can limit the position of the plug 122 to prevent the plug 122 from being completely retracted into the liquid storage cavity. In a specific embodiment, the diameter of the limiting portion 1221 is greater than the diameter of the plug 122. In addition, the limiting portion 1221 can also be an annular flange provided on the plug 122.

[0042] See also Figure 1 In one embodiment of the utility model, a plurality of scale lines 1211 are arranged at intervals on the liquid storage tube 121. The scale lines 1211 facilitate workers to judge the storage amount of the oil-water mixture in the liquid storage chamber; during the working process, workers can confirm the storage amount of the oil-water mixture in the liquid storage chamber according to the scale lines 1211, so as to discharge the oil-water mixture in the liquid storage chamber in time when the oil-water mixture in the liquid storage tank 121 is almost full, so as to avoid blockage of the tube body 110.

[0043] See also Figure 1 In one embodiment of the utility model, a connection portion 130 is formed at the liquid outlet 1111, and the liquid storage component 120 is threadedly connected to the connection portion 130.

In addition, the liquid storage tube 121 and the connection portion 130, as well as the plug 122 and the liquid storage tube 121, are connected by threaded connection, which can ensure the sealing of the accumulated liquid discharge device 100 and prevent leakage of the oil-water mixture. Accordingly, in order to improve the sealing performance, sealant can be added between the liquid storage tube 121 and the connection portion 130 and between the plug 122 and the liquid storage tube 121.
