Description

Technical Field

[0001] The present invention relates to the field of carbon making, and particularly relates to a distillation furnace. Background Art

[0002] In life and production, there are a large number of organic wastes, such as paper and food residues in domestic waste, and also straws and woods in agricultural production. If these wastes are directly discarded, they need a long time to decompose, and a large amount of space is required to stack the wastes, which brings trouble to management. And some organic wastes can be made into carbon, such as wood recycled to make charcoal. Charcoal is a relatively clean energy source with high calorific value, long burning time, and smokeless and odorless combustion. Therefore, recycling organic wastes into carbon is an effective method for treating organic wastes. However, traditional kilns or carbonization devices have only a single furnace body, and the entire carbon-making work is completed in the same furnace body. The time required for carbon making is long, the efficiency is low, the control of time and temperature in each stage of carbon making is complex, and the technical level requirements for workers are relatively high. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention provides a distillation furnace of a carbon making machine, which can crack out grease from organic wastes and drain away the grease, facilitating the subsequent carbonization of organic wastes.

The distillation furnace feeds and discharges materials through the front furnace door and the rear furnace door, that is, the organic wastes enter and exit the furnace body. The circulation fan drives the air heated by the heating device in the furnace body, and the hot air heats the materials in the furnace body and causes the materials to crack out grease, and then the grease is drained away through the oil filtering component.

[0027] Referring to Figure 1 and Figure 2 , the present invention discloses a distillation furnace, which includes a furnace body 100, a front furnace door 200, a rear furnace door 300, a heating device 400, a circulation fan 500 and an oil filtering assembly 170. The distillation furnace feeds and discharges materials through the front furnace door 200 and the rear furnace door 300, that is, organic waste enters and exits the furnace body 100 through the front furnace door 200 and the rear furnace door 300. The circulation fan 500 drives the air heated by the heating device 400 in the furnace body 100, and the hot air heats the materials in the furnace body 100 and causes the organic waste to crack out oil, and then the oil is discharged through the oil filtering assembly 170.

[0028] Among them, a furnace cavity 110 is provided in the furnace body 100. Inlet openings 111 and outlet openings 112 are respectively provided on the front and rear side walls of the furnace body 100. Both the inlet opening 111 and the outlet opening 112 are communicated with the furnace cavity 110. An air duct 120 is provided in the furnace body 100. The inlet 121 and the outlet 122 of the air duct 120 are respectively arranged on two opposite side walls of the furnace cavity 110; the front furnace door 200 is arranged on the front side wall of the furnace body 100 to seal the inlet opening 111; the rear furnace door 300 is arranged on the rear side wall of the furnace body 100 to seal the outlet opening 112; the heating device 400 is arranged in the air duct 120 or in the furnace cavity 110; the circulation fan 500 is arranged in the air duct 120, and the oil filtering assembly 170 is arranged in the air duct 120, and the oil filtering assembly 170 can filter and remove tar in the air.

[0029] Organic waste can be fed into the furnace chamber 110 from the feed inlet 111, and then the front furnace door 200 and the rear furnace door 300 are used to seal the feed inlet 111 and the discharge outlet 112, thereby obtaining a sealed furnace body 100. The air duct 120 and the furnace chamber 110 form a circulation loop, and the circulation fan 500 drives the air to flow in this circulation loop, thereby forming a circulating air flow. The heating device 400 heats the air to increase the temperature of the circulating air flow. The circulating air flow comes into sufficient contact with the organic waste, and the circulating air flow can heat the organic waste, so that the organic waste cracks to produce oil. The oil moves in the circulation loop along with the circulating air flow. When the oil passes through the oil filtering assembly 170, the oil filtering assembly 170 filters out the oil carried by the circulating air flow and discharges it outside the furnace body 100. During the heating process of the organic waste, the heating device 400 can continuously supply heat to the air to increase the temperature of the circulating air flow and ensure the cracking efficiency of the organic waste. Before the carbonization step of the organic waste, cracking the oil from the organic waste first is beneficial to the subsequent further carbonization of the organic waste, increasing the carbonization speed and saving the energy required for the carbonization step.

[0030] In another embodiment, the heating device 400 is arranged inside the furnace chamber 110, and the heating device 400 still has the function of heating the air to increase the temperature of the air.

[0031] Further referring to Figure 2 , the oil filtering assembly 170 includes an oil filtering net 171, an oil cup 172 and an oil discharge pipe 173. The oil filtering net 171 is connected to the side wall of the air duct 120. The oil cup 172 is arranged below the oil filtering net 171. One end of the oil discharge pipe 173 is communicated with the oil cup 172, and the other end of the oil discharge pipe 173 extends outside the furnace body 100. The connection between the oil filtering net 171 and the side wall of the air duct 120 enables the circulating air flow to pass through the oil filtering net 171 when flowing in the air duct 120. The oil filtering net 171 filters out the oil carried by the circulating air flow. The filtered oil drops into the oil cup 172 below the oil filtering net 171 under the action of gravity, and the oil in the oil cup 172 is discharged outside the furnace body 100 through the oil discharge pipe 173.

[0032] In some embodiments, the oil filtering net 171 is funnel-shaped, and the peripheral side of the oil filtering net 171 is connected to the inner peripheral wall of the air duct 120. The lower end of the oil discharge pipe 173 is communicated with the oil cup 172. The oil discharge pipe 173 is inclined, and the position of the other end of the oil discharge pipe 173 is lower than the position of the oil cup 172 to facilitate the oil to flow out of the furnace body 100 through the oil discharge pipe 173. A valve is provided at the other end of the oil discharge pipe 173.

[0033] In some embodiments of the present invention, a left partition 130, an upper partition 140, and a right partition 150 are provided inside the furnace body 100. The left partition 130, the upper partition 140, the right partition 150, the top wall of the furnace cavity 110, and the left and right side walls of the furnace cavity 110 enclose an air duct 120. An inlet 121 and an outlet 122 are respectively provided on the left partition 130 and the right partition 150.

[0034] In another embodiment, the inlet 121 and the outlet 122 are respectively provided on the right partition 150 and the left partition 130.

[0035] That is to say, the air duct 120 is provided on the inner wall of the furnace body 100. The left partition 130, the upper partition 140, and the right partition 150 can be conveniently and quickly installed on the inner wall of the furnace body 100, so as to complete the erection of the air duct 120. The production speed of the air duct 120 is fast, the difficulty is low, and the labor intensity of processing the air duct 120 is reduced. The air duct 120 restricts and guides the flow direction of air. The inlet 121 and the outlet 122 are oppositely arranged, which is conducive to the rapid flow of circulating air and the sufficient contact of the flowing air with the organic waste, so that the organic waste in each area is dehydrated and dried uniformly.

[0036] In some embodiments of the present invention, the inlet 121 is a plurality of first through holes provided on the right partition 150, and the outlet 122 is a plurality of second through holes provided on the left partition 130. The plurality of first through holes are distributed on the right partition 150, and the plurality of second through holes are distributed on the left partition 130, which can make the circulating air flow through the entire furnace cavity 110, avoid dead corners in the furnace cavity 110 that cannot be blown by the circulating air, and then synchronously dry the organic waste in each area of the furnace cavity 110. The number of the first through holes and the second through holes can be determined according to the area of the partition where they are located, and the first through holes and the second through holes are evenly distributed on the partition where they are located.

[0037] In some embodiments of the present invention, a first guide rail 160 and a second guide rail are respectively provided on the front and rear side walls of the furnace body 100. The front furnace door 200 is slidably connected to the first guide rail 160, and the rear furnace door 300 is slidably connected to the second guide rail. Sealing gaskets (not shown in the figure) are provided between the front furnace door 200 and the front side wall of the furnace body 100 and between the rear furnace door 300 and the rear side wall of the furnace body 100. The front furnace door 200 can be conveniently and quickly moved through the first guide rail 160 to open or close the furnace inlet 111, and the rear furnace door 300 can be conveniently and quickly moved through the second guide rail to open or close the furnace outlet 112. The first guide rail 160 and the second guide rail reduce the friction force when the front furnace door 200 and the rear furnace door 300 slide, and the sealing gaskets can make the furnace inlet 111 and the furnace outlet 112 have good sealing performance, avoiding heat loss due to air leakage of the furnace body 100.

[0038] Specifically, there are two first guide rails 160 and two second guide rails. The two first guide rails 160 are respectively arranged on the front side wall of the furnace body 100 on the left and right sides of the furnace inlet 111. The two first guide rails 160 are parallel to each other. The front furnace door 200 straddles the two first guide rails 160, so that the left and right ends of the front furnace door 200 are balanced in force, the movement is smoother, and the wear of the front furnace door 200 and the first guide rails 160 can be effectively reduced, and the service life of the front furnace door 200 and the first guide rails 160 is improved; the two second guide rails are respectively arranged on the rear side wall of the furnace body 100 on the left and right sides of the furnace outlet 112. The two second guide rails are parallel to each other. The rear furnace door 300 straddles the two second guide rails, so that the left and right ends of the rear furnace door 300 are balanced in force, the movement is smoother, and the wear of the rear furnace door 300 and the second guide rails can be effectively reduced, and the service life of the rear furnace door 300 and the second guide rails is improved.

[0039] In some embodiments of the present invention, the front furnace door 200 and the rear furnace door 300 are both connected with a driving mechanism. The driving mechanism can drive the front furnace door 200 and the rear furnace door 300 to slide to open and close the furnace inlet 111 and the furnace outlet 112. The driving mechanism can replace the staff to manually push the front furnace door 200 and the rear furnace door 300, reduce the work burden of the staff, and avoid the staff getting too close to the furnace body 100, reducing the chance of the staff directly touching the front furnace door 200 and the rear furnace door 300, thereby improving the safety of the distillation furnace.

[0040] In some embodiments of the present invention, the driving mechanism includes a cooperating gear 600 and a rack 700. The gear 600 and the rack 700 are respectively arranged on the furnace body 100 and on the front furnace door 200 and the rear furnace door 300. The gear 600 is rotatably arranged on the furnace body 100. The gear 600 and the rack 700 are meshed with each other. Rotating the gear 600 can drive the rack 700 to move linearly, and the rack 700 will carry the front furnace door 200 and / or the rear furnace door 300 to move.

[0041] The driving mechanism further includes a motor (not shown in the figure). The motor can be fixedly arranged on the furnace body 100. The output end of the motor is connected to the gear 600, and the motor drives the gear 600 to rotate.

[0042] Furthermore, racks 700 are arranged at the left and right ends of the front furnace door 200 and the left and right ends of the rear furnace door 300. Gears 600 are arranged in the areas of the furnace body 100 corresponding to the racks 700. All the gears 600 are connected to the same motor and all the gears 600 rotate at the same speed, so that the front furnace door 200 and the rear furnace door 300 can move synchronously, thereby opening or closing the furnace inlet 111 and the furnace outlet 112 synchronously, and the left and right ends of the front furnace door 200 are balanced in force, and the left and right ends of the rear furnace door 300 are also balanced in force.

[0043] In some embodiments, the driving mechanism may be a cylinder, which pushes the front furnace door 200 and the rear furnace door 300 to move, thereby opening or closing the furnace inlet 111 and the furnace outlet 112.

[0044] In some embodiments of the present invention, the heating device 400 is arranged at the rear end of the circulation fan 500, so that the circulated air can abut against the organic waste faster after being heated, avoiding the heat of the circulated air being absorbed by the long air duct 120 or other components. Avoid arranging the heating device 400 at the front end of the circulation fan 500, so as to avoid the heated circulated air immediately raising the temperature of the circulation fan 500, which can avoid wasting the heat of the circulated air and avoid the temperature of the circulation fan 500 being too high.

[0045] The heating device 400 includes a plurality of electric heating tubes. The electric heating tubes have a high power and are convenient to set, and are very suitable for heating the air in the air duct 120. The electric heating tubes are in a U shape, and a plurality of heat dissipation fins are arranged on the electric heating tubes.

[0046] See Figure 3 , a horizontal baffle 180 is arranged between the upper partition plate 140 and the top wall of the furnace cavity 110. The baffle 180 divides the cavity between the upper partition plate 140 and the top wall of the furnace cavity 110 into an upper cavity and a lower cavity. The upper cavity is communicated with the outlet 122, and the lower cavity is communicated with the inlet 121. A third through hole is arranged on the baffle 180. The circulation fan 500 is a centrifugal fan, and the circulation fan 500 is arranged at the third through hole. The air inlet and air outlet of the circulation fan 500 face the lower cavity and the upper cavity respectively. A vertical air guide plate is arranged in the upper cavity, and the air guide plate guides the circulated air to the outlet 122. The heating device 400 is arranged in the upper cavity. The oil filter net 171 covers the third through hole, so that all the air of the circulated air needs to pass through the oil filter net 171, improving the oil filtering effect of the oil filter net 171.

[0047] In some embodiments of the present invention, a temperature probe 800 and a pressure relief valve 900 are further arranged on the furnace body 100. The temperature measuring end of the temperature probe 800 and the inlet end of the pressure relief valve 900 both extend into the furnace cavity 110. The temperature in the furnace cavity 110 can be monitored at any time through the temperature probe 800, so as to control the temperature in the furnace cavity 110 within a suitable range value. The pressure relief valve 900 can avoid the air pressure in the furnace cavity 110 being too high, thereby protecting the distillation furnace itself.

[0048] In some embodiments of the present invention, a rail (not shown in the figure) is arranged in the furnace cavity 110. The rail can support and guide the turnover trolley for transporting organic waste. The rail facilitates the entry and exit of organic waste into and out of the furnace. By transporting the organic waste in a directional manner through the turnover trolley, the labor intensity and workload of the staff can be reduced. The rail is arranged. Further, the rail extends outside the furnace body 100, and avoidance holes for avoiding the rail are arranged on both the front furnace door 200 and the rear furnace door 300.

[0049] In this embodiment, the furnace body 100 includes a support frame and a cover plate covering the support frame. The support frame is cubic, so the bottom wall (not shown in the figure) of the furnace cavity 110 of the furnace body 100 is also cubic in overall structure. The temperature measuring end of the temperature probe 800 and the inlet end of the pressure relief valve 900 both extend into the air duct 120.

[0050] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
