DETAILED DESCRIPTION

[0033] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Embodiment 1:

[0036] like Figures 1 to 5As shown, this embodiment provides a horseshoe flame kiln smoke exhaust device, including a shell 1, a heat-conducting metal block 2, a positioning component 3, a water tank 4, a smoke inlet 5 and a smoke outlet 6 arranged on the upper side of the shell 1.

[0037] The shell 1 used for exhausting smoke from the horseshoe flame kiln is D-shaped in appearance, and the front side of the upper end of the outer part is convex. A square smoke inlet 5 is provided at the lower end of the outer front side of the shell 1, and a square smoke outlet 6 is provided on the upper side of the convex upper end of the outer part of the shell 1. The smoke inlet 5 and the smoke outlet 6 are connected by the first smoke exhaust cavity 7, the second smoke exhaust cavity 8 and the third smoke exhaust cavity 9 provided inside the shell 1, which penetrate the interior of the entire shell 1, wherein the first smoke exhaust cavity 7 is in a lying L shape, and the bend is bent upward at the rear side of the shell 1. The second smoke exhaust chamber 8 is in an N shape, the third smoke exhaust chamber 9 is in an L shape and is bent toward the rear, the first smoke exhaust chamber 7 is connected to the smoke inlet 5, the third smoke exhaust chamber 9 is connected to the smoke outlet 5, and the front and rear lower ends of the second smoke exhaust chamber 8 are respectively connected to the bend at the rear side of the third smoke exhaust chamber 9 and the bend at the rear side of the first smoke exhaust chamber 7, so that the smoke exhaust passage inside the entire shell 1 is bent, the distance that the smoke circulates in the shell 1 is increased, the time for the shell 1 to absorb the heat of the smoke is increased, and the pressure difference is used to accelerate the speed of smoke discharge.

[0038] A mounting slot 10 is provided on the upper side of the smoke inlet 5 at the lower side of the outer front end of the shell 1. The mounting slot 10 passes through the bend at the lower end of the third smoke exhaust chamber 9 and is used to install a heat-conducting metal block 2 inside it. The heat-conducting metal block 2 is concave in shape, and the upper side is convenient for collecting cigarette ash dropped during smoke exhaust. In order to fix the heat-conducting metal block 2 inside the mounting slot 10 and facilitate disassembly and assembly, a clamping block 301 is installed on the rear side of the heat-conducting metal block 2, and a clamping slot 12 for the clamping block 301 to be clamped is provided on the rear side of the mounting slot 10.

[0039] A plurality of evenly distributed movable holes 11 that are interconnected are provided on the front sides of both ends of the heat-conducting metal block 2. The two ends inside the movable hole 11 gradually become smaller to prevent the small balls on both sides of the movable hole 11 from falling out. A squeezing spring 303 is provided inside each movable hole 11. The two ends of the squeezing spring 303 are connected to the clamping small balls 302 on both sides. The small balls are squeezed to both sides by the squeezing spring 303. The clamping small balls 302 are squeezed into a plurality of evenly distributed positioning grooves 13 provided at the front ends of both sides of the installation slot 10 to achieve the positioning of the heat-conducting metal block 2. The heat-conducting metal block 2 is dragged out of the installation slot 10 by the handle 14 installed on the front side of the heat-conducting metal block 2 to achieve the quick installation and quick removal functions of the heat-conducting metal block 2.

[0040] Embodiment 2:

[0041] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0042] In order to increase the temperature difference between the top of the first smoke exhaust chamber 7 and the top of the second smoke exhaust chamber 8, a water tank 4 is provided on the upper side of the outer shell 1 and the rear side of the protrusion. By injecting water into the water tank 4 and utilizing the large specific heat capacity of water, the top of the inner shell 1 is cooled to form a larger temperature difference. The heat-conducting metal block 2 is made of copper, which has a larger thermal conductivity and a relatively low price.

[0043] When the horseshoe flame kiln is firing glass or ceramics, the discharged high-temperature flue gas enters the interior of the shell 1 from the smoke inlet 5 and transfers heat to the heat-conducting metal block 2. Since the temperature at the front end of the first smoke exhaust chamber 7 is relatively high, the gas expansion there drives the flue gas to flow backward along the interior of the first smoke exhaust chamber 7. After reaching the bend at the rear end of the first smoke exhaust chamber 7, since the water tank 4 arranged at the upper end of the shell 1 and its own temperature are lower than the temperature of the smoke inlet 5, the flue gas rises with the hot gas and floats to the top of the second smoke exhaust chamber 8. The heat is transferred outward, the water in the water tank 4 absorbs most of the heat, and the flue gas is obstructed by the top of the second smoke exhaust chamber 8 and gathers, causing the air pressure at the top of the second smoke exhaust chamber 8 to increase, and finally exceed the air pressure inside the first smoke exhaust chamber 7.

[0044] Moreover, since there is always hot air expanding at the smoke inlet 5, the air flow is pushed toward the inside of the second smoke exhaust chamber 8. After the temperature of the heat-conducting metal block 2 increases, the temperature at the connection between the second smoke exhaust chamber 8 and the third smoke exhaust chamber 9 increases, the gas expands, and the air pressure decreases. The smoke gathered at the top of the second smoke exhaust chamber 8 flows into the inside of the third smoke exhaust chamber 9 under the action of the low-pressure attraction on the upper side of the heat-conducting metal block 2 and the heating and expansion of the smoke in the first smoke exhaust chamber 7. Under the influence of the high temperature of the heat-conducting metal block 2, the air on its upper side expands, and the smoke itself has a certain residual temperature and a density lower than that of the air. It floats from the inside of the third smoke exhaust chamber 9 to the smoke outlet 6, accelerating the discharge of the smoke. After floating upward to a certain height, some smoke particles fall downward and are collected by the heat-conducting metal block 2. When the inside of the shell 1 needs to be cleaned, the heat-conducting metal block 2 can be pulled out to clean the collected smoke particles.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
