[0035] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0036] Please refer to Figures 1 to 8 , a furnace waste slag collection device, comprising a furnace body 1 and a collection component 2;

[0037] The kiln body 1 includes a furnace top 11, a furnace bottom 12, a circulation fan 13, a circulation valve, a circulation pipe 14 and collection tanks 15 opened on both sides of the furnace bottom 12; the furnace top 11 has a long strip of air blowing port 16 arranged in the middle toward the furnace bottom 12, and the air blowing port 16 is parallel to the collection tank 15; the circulation fan 13 includes an air inlet and an air outlet, and the air outlet is connected to the air blowing port 16; the circulation pipe 14 is connected to the collection tank 15 respectively; a detachable filter screen slot 17 is provided in the collection tank 15; one end of the circulation pipe 14 is forked and connected to the bottom of the two collection tanks 15 respectively, and the other end is connected to the air inlet through the circulation valve;

[0038] The collecting assembly 2 includes a refrigerator, a heater, and two groups of collecting modules. The collecting modules include a motor 21, a collecting roller 22, a first three-way valve, and a second three-way valve. The collecting roller 22 includes an outer roller body 221 and a temperature-regulating pipe 222 disposed therein. The motor 21 drives the outer roller body to rotate. The two groups of outer roller bodies 221 are respectively disposed in two collecting tanks 15 and above the filter screen tank 17. The two ends 222 of the temperature-regulating pipe are respectively connected to the first three-way valve 223 and the second three-way valve 224. The refrigerator includes a first inlet 23 and a first outlet 24. The heater includes a second inlet 25 and a second outlet 26. The first inlet 23 and the second inlet 25 are respectively connected to the first three-way valve 223, and the first outlet 24 and the second outlet 26 are respectively connected to the second three-way valve 224.

[0039] When the furnace body 1 is in operation, the refrigerator cools the outer roller, and the circulating fan 13 is turned on to blow the air flow containing tar and waste residue to the furnace bottom 12 to blow the generated tar and waste residue to the collection tank 15. The tar-containing gas cokes on the surface of the outer roller and the tar in the condensed state absorbs the fine waste residue, and the waste residue that cannot be absorbed by the tar falls into the filter mesh tank 17; when the furnace body 1 stops operating, the heater heats the outer roller, and the blocks formed by the adsorbed fine waste residue and tar are softened and separated from the outer roller and fall into the filter mesh tank 17.

[0040] From the above description, it can be known that the air flow blown out by the circulating fan 13 can flow to both sides through the long strip air blowing port 16 and in parallel with the collecting tank 15, so that the gas containing tar and fine waste residue is blown to the collecting tank 15, and at the same time the refrigerator cools the outer roller body, and the tar gas cokes on the surface of the outer roller body and the tar in the condensed state can absorb the fine waste residue, and is continuously circulated by the circulating fan 13, a layer of tar and a layer of fine waste residue are formed, and a cylindrical porous loose structure can be formed. This structure can continue to filter out most of the tar and particulate matter like a sponge, which greatly reduces the load of the existing filtration system, extends its service life and reduces costs; and large pieces of waste residue can be blown into the filter mesh groove 17 under the action of the air flow, so that most of the waste residue generated during the kiln processing process is removed. Tar, fine waste slag and large waste slag can be collected along with the airflow when the furnace body 1 is in operation, and in subsequent cleaning, only large waste slag that cannot be blown by the airflow needs to be cleaned, thereby reducing the difficulty of subsequent cleaning. At the same time, the tar and fine waste slag mixture on the char collection roller 22 can be heated by the heater to obtain a certain fluidity and fall into the filter mesh groove 17, so that the filter mesh groove 17 only needs to be cleaned during cleaning. At the same time, the collected tar and waste slag mixture can be centrally processed, thereby further reducing the exhaust gas treatment cost; and the air inlet 16 is arranged in the middle of the furnace top 11, which can make the material in the furnace body blown more evenly, and the flow field in the furnace will not be skewed, and the jet penetrates the furnace bottom 12 and then recovers to both sides, and the blown gas can be effectively mixed with the original gas.

[0041] Furthermore, an air supply port 131 is provided on the air inlet, and an air supply valve is provided on the air supply port 131 .

[0042] From the above description, it can be seen that by setting the air supply port 131, it is convenient to supply air to the furnace body 1. The new gas blown in can penetrate the furnace bottom 12 and then be recovered to both sides to form an effective mixture with the original gas, which facilitates the reaction in the furnace.

[0043] Furthermore, the circulation pipe 14 is further provided with a tail outlet 19 and an exhaust valve provided on the tail outlet 19;

[0044] When air needs to be replenished inside the furnace body 1, the air replenishment valve is opened, the circulation valve is closed, and the circulation pipe 14 and the tail outlet 19 are connected.

[0045] As can be seen from the above description, by providing the tail exhaust port 19, it is possible to facilitate exhaust when replenishing air, thereby avoiding the situation where the internal air pressure is high and air cannot be replenished.

[0046] Furthermore, the furnace waste slag collection device is installed on the ground;

[0047] The lowest point of the collecting trough 15 is parallel to the ground; a connecting slope 3 is provided between the furnace bottom 12 and the ground.

[0048] Furthermore, first tracks 4 are provided on the ground on both sides of the connecting slope 3 corresponding to the collecting trough 15;

[0049] A plurality of pulleys cooperating with the first track 4 are provided at the bottom of the filter screen tank 17 .

[0050] It can be seen from the above description that the arrangement of the track and the pulley can facilitate the extraction of the filter screen slot 17 for cleaning, thereby improving efficiency.

[0051] Furthermore, a second track is provided in the collecting tank 15 , and a gap 41 is provided between the second track and the first track 4 and the second track and the first track 4 are located on the same straight line.

[0052] It can be seen from the above description that the provision of the second track can facilitate the entry, exit, disassembly and cleaning of the filter screen slot 17.

[0053] Furthermore, the kiln body 1 includes a furnace door 18, a furnace opening is formed on the kiln body 1, and the connecting slope 3 is located on one side of the furnace opening;

[0054] The furnace door 18 is in an inverted concave shape and is disposed on the furnace opening. When the furnace door 18 moves downward and closes, it cooperates with the spacer 41 to close the furnace body 1 .

[0055] It can be seen from the above description that the collecting tank 15 can also be closed by the inverted concave-shaped furnace door 18 .

[0056] Furthermore, a baffle 27 is provided above the collecting roller 22 , and the baffle 27 is connected to the inner wall of the kiln body 1 through a connecting frame 28 .

[0057] As can be seen from the above description, the baffle 27 is provided to prevent falling objects in the kiln from damaging the collecting roller 22 .

[0058] Furthermore, the baffle 27 is an angle steel and the connection is arranged upward.

[0059] From the above description, it can be seen that by adopting angle steel, the structure is simple, the cost is low, and the connection is at a right angle, which can make the falling materials move to both sides or directly impact and break.

[0060] Furthermore, a pull ring is provided on the filter screen slot 17 .

[0061] It can be seen from the above description that the setting of the pull ring can facilitate the entire filter slot 17 to be pulled out for processing. Example 1
