Description

Technical Field

[0001] The utility model relates to the technical field of ash frying machines, and particularly relates to a dust removal device for an ash frying machine. Background Technique

[0002] An ash frying machine is a device used to process metal ash such as aluminum ash and zinc ash, and its design and function aim to achieve efficient separation and recycling of metal ash.

[0003] The working principle of the ash frying machine is mainly to melt and separate useful components such as metallic aluminum and alumina in the metal ash through heating and stirring. During the ash frying process, the metal ash is fed into the main body of the ash frying machine. Through continuous stirring by the stirring system and heating by the heating system, the metal ash gradually melts to form a mixture of metal liquid and slag. As the stirring continues, the metal liquid and slag are gradually separated. The metal liquid is collected and reused, while the slag is discharged or further processed.

[0004] In the prior art, when the ash frying machine works, a large amount of smoke and dust will be generated, and this part of the smoke and dust will be discharged through the dust suction and dust removal device above the ash frying machine. For example, in a dust removal device for an aluminum ash frying machine with the application number 201921189026.X, a cyclone dust collector is used for dust removal during use. However, the temperature of the smoke and dust discharged from the ash frying machine is very high, and the above disclosed device does not utilize any heat of these smoke and dust, thus easily causing unnecessary heat waste. Therefore, an improved dust removal device for an ash frying machine is needed to solve this problem. Content of the Utility Model

[0005] The purpose of the utility model is to provide a dust removal device for an ash frying machine to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A dust removal device for an ash frying machine, including a fixed frame. A aluminum loading basin is fixedly arranged at the lower end inside the fixed frame. A transmission rod is movably arranged inside the fixed frame at the upper end through a bearing. A stirrer is fixedly arranged at the lower end of the transmission rod. A motor is fixedly arranged inside the fixed frame on one side of the transmission rod. The output shaft end of the motor is in transmission connection with the transmission rod through a speed reducer. A heat exchange mechanism for absorbing the heat inside the flue gas is arranged on one side of the surface of the fixed frame. The heat exchange mechanism includes a connecting pipe, a heat exchange chamber, a water inlet pipe, and a water outlet pipe. A connecting pipe is fixedly arranged on one side of the surface of the fixed frame. There are multiple connecting pipes and they are evenly spaced and respectively arranged on one side of the surface of the fixed frame. A heat exchange chamber is fixedly arranged on the surface of the fixed frame outside the connecting pipe. A water inlet pipe is fixedly arranged at the lower end of the heat exchange chamber. A water outlet pipe is fixedly arranged at the upper end of the heat exchange chamber.

[0007] Preferably, a filtering mechanism for filtering dust in the flue gas is provided on one side of the surface of the heat exchange chamber; the filtering mechanism includes a filtering chamber, an air outlet pipe, a smoke exhaust port, and a filter element. A filtering chamber is fixedly arranged on one side of the surface of the heat exchange chamber. The inside of the fixed frame is communicated with the inside of the filtering chamber through a connecting pipe. An air outlet pipe is fixedly arranged at the upper end of the filtering chamber, and a smoke exhaust port is fixedly arranged at the lower end of the filtering chamber. A filter element is clamped inside the smoke exhaust port. The filtering mechanism can filter the dust after cooling and heat exchange to filter out the dust particles in the smoke; the filtering principle of the device is as follows: the connecting pipe sends the flue gas to be filtered into the filtering chamber, and then the flue gas passes through the outside of the filter element and enters the inside of the filter element after filtering, and then enters the air outlet pipe from the through hole at the upper end inside the filter element, so that the filtering can be completed.

[0008] Preferably, a first connecting flange is arranged between the lower end of the filter element and the smoke exhaust port. The first connecting flange can conveniently fixedly connect the filter element and the smoke exhaust port. In this way, when ash cleaning is required, the first connecting flange can be disassembled to disassemble the filter element for cleaning and to conveniently discharge the soot inside the filtering chamber.

[0009] Preferably, a sealing ring is fixedly arranged between the outer surface of the lower end of the air outlet pipe and the filter element. When the filter element is fixed inside the filtering chamber through the first connecting flange, the outer surface of the upper end of the filter element and the outer surface of the lower end of the air outlet pipe will be closely attached. At this time, interference connection and sealing are carried out through the sealing ring, so that the contact position between the filter element and the filter pipe is sealed, so that the flue gas can only enter the inside of the filter element from the outside of the filter element and then enter the inside of the air outlet pipe from the inside of the filter element.

[0010] Preferably, second connecting flanges are fixedly arranged at one ends of the water inlet pipe and the water outlet pipe. The second connecting flanges can conveniently connect the water inlet pipe and the water outlet pipe to other pipes.

[0011] Preferably, columns are fixedly arranged at the four circumferential positions of the lower end surface of the fixed frame. The columns can provide stable ground support force for the device.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] 1. The dust removal device of the utility model can be externally connected to a blower through an air outlet pipe, so as to generate negative pressure inside the air outlet pipe and the filter chamber. In this way, negative pressure will be generated inside the connecting pipe, and the flue gas generated inside the fixed frame will flow into the filter chamber through the connecting pipe. At this time, the hot flue gas is divided by multiple connecting pipes, and then heat exchange liquid is injected into the heat exchange chamber through the liquid inlet pipe, and then the heat exchange liquid is discharged from the liquid outlet pipe. In this way, the heat exchange liquid can fully contact the hot air inside the multiple connecting pipes for heat exchange, so that the high-temperature heat in the soot can be exchanged out, and hot water can be generated for other uses. In this way, a large amount of heat will not be wasted, and the use effect is good. At the same time, the cooled flue gas is not easy to damage the equipment during filtration, and the use effect is good.

[0014] 2. The subsequent cleaning of dust and filter elements of the utility model is relatively convenient. When the filter element needs to be cleaned, only the first connecting flange needs to be disassembled to take out the filter element, and the filter element can be cleaned and the soot inside the filter chamber can be conveniently discharged.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-6 , the present invention provides a technical solution: a dust removal device for a ash frying machine, including a fixed frame 1, a aluminum loading basin 2 is fixedly arranged at the lower end inside the fixed frame 1, a transmission rod 3 is movably arranged at the upper end inside the fixed frame 1 through a bearing, a stirrer 4 is fixedly arranged at the lower end of the transmission rod 3, a motor 5 is fixedly arranged inside the fixed frame 1 on one side of the transmission rod 3, and the output shaft end of the motor 5 is in transmission connection with the transmission rod 3 through a speed reducer. A heat exchange mechanism for absorbing the heat inside the flue gas is arranged on one side of the surface of the fixed frame 1. The heat exchange mechanism includes a connecting pipe 6, a heat exchange chamber 7, a water inlet pipe 8, and a water outlet pipe 9. A connecting pipe 6 is fixedly arranged on one side of the surface of the fixed frame 1. There are multiple connecting pipes 6 and they are evenly spaced on one side of the surface of the fixed frame 1. A heat exchange chamber 7 is fixedly arranged on the surface of the fixed frame 1 outside the connecting pipe 6. A water inlet pipe 8 is fixedly arranged at the lower end of the heat exchange chamber 7, and a water outlet pipe 9 is fixedly arranged at the upper end of the heat exchange chamber 7.

[0024] A filtering mechanism for filtering the dust in the flue gas is arranged on one side of the surface of the heat exchange chamber 7; the filtering mechanism includes a filtering chamber 10, an air outlet pipe 11, a smoke exhaust port 12, and a filter element 13. A filtering chamber 10 is fixedly arranged on one side of the surface of the heat exchange chamber 7. The inside of the fixed frame 1 is in mutual communication with the inside of the filtering chamber 10 through the connecting pipe 6. An air outlet pipe 11 is fixedly arranged at the upper end of the filtering chamber 10, a smoke exhaust port 12 is fixedly arranged at the lower end of the filtering chamber 10, and a filter element 13 is snap-fitted inside the smoke exhaust port 12. The dust in the cooled and heat-exchanged soot can be filtered through the filtering mechanism to filter out the dust particles in the soot; and the filtering principle of this device is as follows: the connecting pipe 6 sends the flue gas to be filtered into the inside of the filtering chamber 10, and then the flue gas passes through the outside of the filter element 13 and is filtered and then enters the inside of the filter element 13, and then enters the air outlet pipe 11 from the through hole at the upper end inside the filter element 13, so that the filtering can be completed.

[0025] A first connection flange 14 is arranged between the lower end of the filter element 13 and the smoke exhaust port 12. Through the first connection flange 14, the filter element 13 can be conveniently and fixedly connected to the smoke exhaust port 12. In this way, when ash cleaning is required, the first connection flange 14 can be disassembled to disassemble the filter element 13 for cleaning and can conveniently discharge the soot inside the filtering chamber 10.

[0026] A sealing ring 17 is fixedly arranged between the outer surface of the lower end of the air outlet pipe 11 and the filter element 13. When the filter element 13 is fixed inside the filter chamber 10 through the first connection flange 14, the outer surface of the upper end of the filter element 13 and the outer surface of the lower end of the air outlet pipe 11 will be closely attached. At this time, interference connection sealing is carried out through the sealing ring 17, so that the contact position between the filter element 13 and the filter pipe is sealed with each other, so that the flue gas can only enter the inside of the filter element 13 from the outside of the filter element 13, and then enter the air outlet pipe 11 from the inside of the filter element 13;

[0027] Second connection flanges 15 are fixedly arranged at one ends of the water inlet pipe 8 and the water outlet pipe 9. Through the second connection flanges 15, it is convenient to externally connect other pipes to the water inlet pipe 8 and the water outlet pipe 9;

[0028] Columns 16 are fixedly arranged at the four peripheral parts of the lower surface of the fixed frame 1. Through the columns 16, stable ground support force can be provided for the device.

[0029] Working principle: When using this device, the aluminum block to be heated is placed into the aluminum basin 2. Subsequently, high temperature is applied inside the aluminum basin 2 to melt the aluminum block so that the aluminum block and dust are separated. At this time, a large amount of fly ash will be generated due to the high temperature. At this time, a blower can be externally connected to the air outlet pipe 11, so that negative pressure is generated inside the air outlet pipe 11 and the filter chamber 10. In this way, negative pressure will be generated inside the connecting pipe 6, and the flue gas generated inside the fixed frame 1 will flow into the filter chamber 10 from the connecting pipe 6. At this time, the hot flue gas is shunted by the multiple connecting pipes 6. Subsequently, heat exchange liquid is injected into the heat exchange chamber 7 through the liquid inlet pipe, and then the heat exchange liquid is discharged from the liquid outlet pipe. In this way, the heat exchange liquid can fully contact with the hot air inside the multiple connecting pipes 6 for heat exchange, so that the high temperature heat in the soot can be exchanged out, and thus hot water can be generated for other uses. In this way, a large amount of heat will not be wasted and the use effect is better;

[0030] Subsequently, the soot after heat exchange and cooling is sent into the filter chamber 10 through the connecting pipe 6. Subsequently, the flue gas passes through the filter from the outside of the filter element 13 and enters the inside of the filter element 13, and then enters the air outlet pipe 11 from the through hole at the upper end inside the filter element 13. In this way, the filtration can be completed;

[0031] Moreover, the subsequent cleaning of the dust and the filter element 13 of this device is relatively convenient. When it is necessary to clean the filter element 13, only the first connection flange 14 needs to be disassembled to take out the filter element 13, and the filter element 13 can be cleaned and the soot inside the filter chamber 10 can be conveniently discharged.
