Description

Technical Field

[0001] The present invention relates to the technical field of furnaces, and particularly relates to a device for collecting furnace waste residues. Background Art

[0002] During the operation of a furnace, a large amount of waste residues will be generated. These waste residues are prone to clogging the furnace and need to be cleaned regularly. Most of the existing furnace waste residues are cleaned manually, and it is necessary for workers to remove the waste residues accumulated at the bottom of the furnace many times, which consumes a large amount of human resources and has a high cost. Moreover, the internal dead corners of the furnace are difficult to clean, resulting in poor cleaning effect of the waste residues and low efficiency of cleaning the furnace waste residues. At the same time, a large amount of fine waste residues will float up during cleaning, affecting the physical health of the workers.

[0003] In addition, the tail gas of traditional furnaces contains tar and various fine waste residues, and additional filtering components are required to filter and treat the tar and waste residues. Therefore, a device for collecting furnace waste residues that can synchronously treat waste residues and tar is needed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a device for collecting furnace waste residues that can synchronously treat waste residues and tar.

[0005] To solve the above technical problem, the technical solution adopted by the present invention is as follows: A device for collecting furnace waste residues, comprising a furnace body and a collection component; The furnace body includes a furnace top, a furnace bottom, a circulation fan, a circulation valve, a circulation pipeline, and collection grooves opened on both sides of the furnace bottom; a long strip-shaped air blowing port is provided in the middle of the furnace top and is arranged parallel to the collection grooves; the circulation fan includes an air inlet and an air outlet, and the air outlet is communicated with the air blowing port; the circulation pipeline is respectively communicated with the collection grooves; a detachable filter mesh groove is arranged in the collection grooves; one end of the circulation pipeline is bifurcated and respectively communicated with the bottoms of the two collection grooves, and the other end is communicated with the air inlet through the circulation valve; The collection component includes a cooler, a heater, and two groups of collection modules. The collection module includes a motor, a collection roller, a first three-way valve, and a second three-way valve. The collection roller includes an outer roller body and a temperature adjustment pipeline arranged inside the outer roller body; the motor drives the outer roller body to rotate, and the two outer roller bodies are respectively arranged in the two collection grooves and above the filter mesh groove; both ends of the temperature adjustment pipeline are respectively communicated with the first three-way valve and the second three-way valve; the cooler includes a first inlet and a first outlet, the heater includes a second inlet and a second outlet, the first inlet and the second inlet are respectively communicated with the first three-way valve, and the first outlet and the second outlet are respectively communicated with the second three-way valve; When the furnace body is operating, the cooler cools the outer roller body, and the circulating fan is turned on to blow air towards the furnace bottom, blowing the generated tar and waste residue towards the collection tank. The tar-containing gas cokes on the surface of the outer roller body, and the tar in the condensed state adsorbs fine waste residue. The waste residue that cannot be adsorbed by the tar falls into the filter screen tank. After the furnace body stops operating, the heater heats the outer roller body to soften the lumps formed by adsorbing fine waste residue and tar, and they detach from the outer roller body and fall into the filter screen tank.

[0006] Preferably, a makeup air inlet is further provided on the air inlet, and a makeup air valve is provided on the makeup air inlet.

[0007] Preferably, the circulating pipeline is further provided with a tail discharge port and an exhaust valve provided on the tail discharge port; When air needs to be supplemented inside the furnace body, the makeup air valve is opened, the circulating valve is closed, and the exhaust valve is opened to exhaust through the tail discharge port.

[0013] Preferably, the baffle is an angle steel and the connection part is upwardly provided.

[0015] The beneficial effects of the present invention are as follows: By having a long strip-shaped air blowing port parallel to the collection tank, the air flow blown by the circulating fan can flow to both sides, causing the gas containing tar and fine waste residues to be blown towards the collection tank. At the same time, the cooler cools the outer roller body. The tar in the tar gas cokes on the surface of the outer roller body, and the tar in the condensed state can adsorb the fine waste residues. Through the continuous circulation of the circulating fan, layer by layer of tar and layer by layer of fine waste residues can form a cylindrical porous and loose structure. This structure can continue to filter out most of the tar and particulate matter like a sponge, greatly reducing the load of the existing filtration system, extending its service life, and reducing costs. Moreover, the large waste residues can be blown into the filter mesh tank under the action of the air flow, enabling most of the tar, fine waste residues, and large waste residues generated during the furnace kiln processing to be collected with the air flow during the operation of the furnace kiln body. During subsequent cleaning, only the large waste residues that cannot be blown by the air flow need to be cleaned, thereby reducing the subsequent cleaning difficulty. At the same time, the mixture of tar and fine waste residues on the coke collection roller can be heated by the heater to obtain a certain fluidity and fall into the filter mesh tank, so that mainly the filter mesh tank needs to be cleaned during cleaning. At the same time, the collected mixture of tar and waste residues can be centrally processed, further reducing the tail gas treatment cost. And the air blowing port is arranged in the middle of the furnace top, which can make the materials in the furnace body be blown more evenly, prevent the flow field in the furnace kiln from skewing, and the jet penetrates the furnace bottom and then recovers towards both sides, and the blown-in gas can form an effective mixture with the original gas.

Specific embodiments

[0017] To describe in detail the technical content, achieved objectives and effects of the present invention, the following is described in conjunction with the embodiments and with reference to the accompanying drawings.

[0018] Please refer to Figures 1 to 8 , a furnace waste residue collection device, including a furnace body 1 and a collection assembly 2; The furnace body 1 includes a furnace top 11, a furnace bottom 12, a circulation fan 13, a circulation valve, a circulation pipeline 14 and collection tanks 15 opened on both sides of the furnace bottom 12; the middle of the furnace top 11 has a long strip-shaped air blowing port 16 facing 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 communicated with the air blowing port 16; the circulation pipeline 14 is respectively communicated with the collection tank 15; a detachable filter mesh tank 17 is arranged in the collection tank 15; one end of the circulation pipeline 14 bifurcates and is respectively communicated with the bottoms of the two collection tanks 15, and the other end is communicated with the air inlet through the circulation valve; The collection assembly 2 includes a cooler, a heater and two groups of collection modules. The collection module includes a motor 21, a collection roller 22, a first three-way valve and a second three-way valve. The collection roller 22 includes an outer roller body 221 and a temperature control pipeline 222 arranged inside the outer roller; the motor 21 drives the outer roller body to rotate, and the two outer roller bodies 221 are respectively arranged in the two collection tanks 15 and above the filter mesh tank 17; both ends of the temperature control pipeline 222 are respectively communicated with the first three-way valve 223 and the second three-way valve 224; the cooler 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 communicated with the first three-way valve 223, and the first outlet 24 and the second outlet 26 are respectively communicated with the second three-way valve 224; When the furnace body 1 is running, the cooler cools the outer roller body. The circulation fan 13 is turned on to blow air towards the furnace bottom 12, blowing the generated gas containing tar and waste residue towards the collection tank 15. The tar gas cokes on the surface of the outer roller body, and the tar in the condensed state adsorbs the fine waste residue. The waste residue that cannot be adsorbed by the tar falls into the filter mesh tank 17. After the furnace body 1 stops running, the heater heats the outer roller body to soften the block formed by adsorbing the fine waste residue and tar, and it detaches from the outer roller body and drops into the filter mesh tank 17.

[0019] As can be seen from the above description, through the long strip-shaped air blowing port 16 which is parallel to the collection tank 15, the air flow blown by the circulation fan 13 can flow to both sides, enabling the gas containing tar and fine waste residue to be blown towards the collection tank 15. At the same time, the cooler cools the outer roller body. The tar gas cokes on the surface of the outer roller body, and the tar in the condensed state can adsorb the fine waste residue. Through the continuous circulation of the circulation fan 13, layer by layer of tar and layer by layer of fine waste residue can form a cylindrical porous and loose structure. This structure can continue to filter out most of the tar and particulate matter like a sponge, greatly reducing the load of the existing filtration system, extending its service life, and reducing costs. Moreover, the large waste residue can be blown into the filter mesh tank 17 under the action of the air flow, enabling most of the tar, fine waste residue, and large waste residue generated during the furnace processing to be collected with the air flow when the furnace body 1 is running. During subsequent cleaning, only the large waste residue that cannot be blown by the air flow needs to be cleaned, thereby reducing the subsequent cleaning difficulty. At the same time, the mixture of tar and fine waste residue on the coke collection roller 22 can obtain a certain fluidity through the heating of the heater and drop into the filter mesh tank 17, so that mainly the filter mesh tank 17 needs to be cleaned during cleaning. At the same time, the collected mixture of tar and waste residue can be centrally processed, further reducing the tail gas treatment cost. And the air blowing port 16 is arranged in the middle of the furnace top 11, which can make the materials in the furnace body be blown more evenly, and the flow field in the furnace will not be skewed. Moreover, the jet penetrates the furnace bottom 12 and then recovers towards both sides, and the blown-in gas can form an effective mixture with the original gas.

[0020] Further, a supplementary air inlet 131 is also arranged on the air inlet, and an air supply valve is arranged on the supplementary air inlet 131.

[0021] As can be seen from the above description, through the setting of the supplementary air inlet 131, it is convenient to supply air into the furnace body 1. The newly blown-in gas can penetrate the furnace bottom 12 and then recover towards both sides to form an effective mixture with the original gas, facilitating the reaction in the furnace.

[0022] Further, the circulation pipeline 14 is also provided with a tail discharge port 19 and an exhaust valve arranged on the tail discharge port 19; When air needs to be supplemented inside the furnace body 1, the air supplement valve opens and the circulation valve closes, and the circulation pipeline 14 is connected to the tail exhaust port 19.

[0023] As can be seen from the above description, by setting the tail exhaust port 19, it is convenient to exhaust air when supplementing air, avoiding the inability to supplement air due to high internal air pressure.

[0024] Furthermore, the furnace waste collection device is installed on the ground; The lowest part of the collection tank 15 is parallel to the ground; a connecting ramp 3 is provided between the furnace bottom 12 and the ground.

[0025] Furthermore, first tracks 4 are provided on the ground corresponding to the two sides of the connecting ramp 3 and the collection tank 15; A plurality of pulleys cooperating with the first tracks 4 are provided at the bottom of the filter screen tank 17.

[0026] As can be seen from the above description, through the setting of the tracks and pulleys, it is convenient to draw out the filter screen tank 17 for cleaning, thereby improving efficiency.

[0027] Furthermore, a second track is provided inside the collection tank 15, and there is a gap 41 between the second track and the first track 4 and they are located on the same straight line.

[0028] As can be seen from the above description, through the setting of the second track, it is convenient for the filter screen tank 17 to enter and exit, be disassembled and cleaned.

[0029] Furthermore, the furnace body 1 includes a furnace door 18, a furnace opening is provided on the furnace body 1, and the connecting ramp 3 is located on one side of the furnace opening; The furnace door 18 is in an inverted concave shape, the furnace door 18 is arranged on the furnace opening, and when the furnace door 18 descends and closes, it cooperates with the gap 41 to realize the closing of the furnace body 1.

[0030] As can be seen from the above description, through the inverted concave-shaped furnace door 18, the collection tank 15 can also be closed.

[0031] Furthermore, a baffle 27 is provided above the collection roller 22, and the baffle 27 is connected to the inner side wall of the furnace body 1 through a connecting frame 28.

[0032] As can be seen from the above description, through the setting of the baffle 27, falling objects in the kiln are prevented from damaging the collection roller 22.

[0033] Furthermore, the baffle 27 is an angle steel and the connection part is upward.

[0034] As can be seen from the above description, by using angle steel, the structure is simple, the cost is low, and the connection part is a right angle, which can make the falling materials move to both sides or directly impact and break.

[0035] Further, a pull ring is provided on the filter screen groove 17.

[0036] As can be seen from the above description, through the setting of the pull ring, it is convenient to pull out the entire filter screen groove 17 for processing. Embodiment 1
