Description

Technical Field

[0001] The utility model relates to the technical field of combustion furnace tail gas emission, in particular to a combustion furnace dust-free emission structure. Background Art

[0002] The combustion furnace can burn fuels such as coal, so that the heat can be used to heat the required objects. During the combustion process, an exhaust gas emission structure is needed to discharge the exhaust gas. However, when the general exhaust gas emission structure is used, a filter is used to filter impurities in the exhaust gas. Although it has the effect of dust-free emission, the filter is fine and prone to clogging, which causes the exhaust gas emission effect to continue to decline, which is not conducive to the continuous use of the device. Utility Model Content

[0003] The purpose of the utility model is to provide a dust-free discharge structure of a combustion furnace to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a dust-free emission structure of a combustion furnace, comprising an exhaust pipe and a filter plate, the exhaust pipe is in an "L" shape, a reset mechanism is arranged inside the exhaust pipe, a supporting mechanism is connected to the side of the reset mechanism, a filter plate is arranged inside the supporting mechanism, a discharge port is arranged at the lower end of the exhaust pipe, and a guiding and collecting mechanism is arranged on the outer side of the discharge port.

[0005] Furthermore, the reset mechanism includes a fixing rod and a fixing spring, the fixing rod is embedded in the exhaust pipe, and a fixing spring is arranged on a side of the fixing rod.

[0006] When the device is in use, when the fixing rod is subjected to a large force and moves, the fixing spring will contract and charge. When the fixing rod is subjected to a small force, the fixing spring will drive the fixing rod to return to its original position.

[0007] Furthermore, the support mechanism includes a slide and an upper fixing plate, the upper end of the exhaust pipe is provided with a slide, the upper fixing plate is slidably arranged inside the slide, and the fixing rod is embedded inside the upper fixing plate.

[0008] When the device is in use, the slideway supports the upper fixing plate so that the upper fixing plate can slide in the slideway, and the fixing rod is embedded in the interior of the upper fixing plate so that the fixing rod moves along with the upper fixing plate.

[0009] Furthermore, a closing plate is embedded in the upper end of the exhaust pipe, and the closing plate and the exhaust pipe are fixed by bolts, and the closing plate is respectively fitted with the upper ends of the upper fixing plate, the fixing rod and the fixing spring.

[0010] The closing plate limits the upper fixing plate, the fixing rod and the fixing spring respectively, thereby preventing the fixing plate, the fixing rod and the fixing spring from moving outward.

[0011] Furthermore, inclined filter plates are arranged on both sides of the lower end of the upper fixed plate, the lower end of the filter plate is connected to the lower fixed plate, the lower fixed plate and the fixing groove are slidably connected, and the fixing groove is opened on the lower end side of the exhaust pipe.

[0012] When the device is in use, the filter plate can filter dust in the gas. When the filter plate is blocked, the filter plate will be subjected to greater force, causing the filter plate to move, and the upper fixed plate and the lower fixed plate will move with the filter plate, and the fixing groove will limit the lower fixed plate to avoid misalignment of the lower fixed plate.

[0013] Furthermore, a cleaning ball is arranged between the two filter plates, and filter holes are evenly distributed on the side of the cleaning ball, and the inner and outer diameters of the filter holes are larger than the central diameter of the filter holes.

[0014] When the gas passes through the cleaning ball, it will drive the cleaning ball to rotate, so that the cleaning ball can clean the filter plate. The filter holes can facilitate the entry and exit of gas and prevent dust from entering the inside of the filter holes.

[0015] Furthermore, the guiding and collecting mechanism includes a material guide rack, a guide plate and a collecting pot. The material guide rack is threadedly arranged on the outside of the discharge port. The material guide rack is arc-shaped, and an opening is arranged at the center of the arc. An inclined guide plate is arranged on the side surface of the lower end of the material guide rack, and a collecting pot is arranged on the outer side of the lower end of the material guide rack.

[0016] Compared with the prior art, the beneficial effects achieved by the utility model are as follows: during use, the utility model will filter the gas when the gas passes through the filter plate. Since the filter plate is inclined, the impurities will flow downward along the inclined surface of the filter plate to the inside of the collecting pot, and the inside of the collecting pot stores water, which can prevent the dust from flowing upward again; at the same time, when the gas flows, it will drive the cleaning ball to rotate, and the cleaning ball can filter the impurities so that the impurities flow out along the discharge hole, and can also make the filter plate vibrate to avoid clogging of the filter plate.
