Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, and in particular to a heat pump hot air circulation intelligent oven drying device. Background Art

[0002] The hot air circulation oven uses a fan circulation air supply method to make the hot air circulate in the oven, so as to achieve the purpose of uniform heating. The specific process is: the air source is driven by the circulating air supply motor (using a contactless switch) to drive the wind wheel through the heater, send the hot air out, and then through the air duct to the inner room of the oven, and then the used air is sucked into the air duct to become the air source and circulate again for heating. This can make the indoor temperature more uniform.

[0003] The existing Chinese patent with publication number CN116608665B discloses a hot air circulation drying device, but the device and the prior art also have the following defects:

[0004] First, the hot air in the oven will carry water vapor when passing through the wet material, and the hot air in the above patent cannot remove the water vapor carried in the hot air when it circulates, so the hot air still contains moisture after circulation, which will eventually affect the normal drying of the wet material;

[0005] Secondly, when drying small aluminum parts, since all the parts to be dried are piled in the drain basket, it is impossible to ensure that the piled parts are heated evenly during drying, which will cause the parts in the middle layer to always be wet, which will eventually affect the drying efficiency;

[0006] Third, a stirring mechanism is added to the traditional industrial oven to stir the wet material to ensure that the wet material is heated evenly. However, the traditional stirring mechanism will cause a large collision with the aluminum parts, so the traditional stirring mechanism cannot be applied to the aluminum parts and is easy to cause damage to the aluminum parts. Therefore, it is necessary to provide a heat pump hot air circulation intelligent oven drying device to solve the above problems. Summary of the invention

When the material is moved, the drain basket is in an inclined state, so that the thumbwheel that moves horizontally will face the aluminum parts that slide downward. In this process, the collision force on the aluminum parts is small, and the thumbwheel can break up all the accumulated aluminum parts, ultimately ensuring that the aluminum parts will not be damaged when they are broken up.

[0020] Secondly, when the dial wheel breaks up the aluminum parts in the drain basket, the drain basket will swing back and forth through the swing mechanism, so that the drain basket is tilted, and the aluminum parts in the drain basket can slide toward the dial wheel. When the aluminum parts slide toward the dial wheel, the shovel plate on the dial wheel will scoop up the aluminum parts, and finally the accumulated aluminum parts will be broken up.

[0021] Thirdly, the hot air in the oven circulates through the hot air circulation component. When the hot air passes through the condensing mechanism, the water vapor carried by the hot air is condensed into liquid water through the condensing mechanism, thereby drying the hot air. The dried hot air will enter the heating mechanism for reheating, ultimately ensuring that the circulated hot air does not contain water vapor and the temperature meets the standard.

[0046] This device is used to dry small aluminum parts. The small aluminum parts need to be washed with water after manufacturing. The washed small aluminum parts are stacked in a drain basket. When drying, several drain baskets are placed on the corresponding support frame 4 in turn. In this process, the drain basket is first tilted, and the aluminum parts in the drain basket are put aside to ensure that there is an empty area in the drain basket. Before placing the drain basket, lift the dial wheel 6, and then place the drain basket flat on the support frame 4. When the drain basket is placed on the support frame 4, release the dial wheel 6, and press the dial wheel 6 down to the empty area in the drain basket through the elastic member. In summary, place After each drain basket is set, the sealing door 2 is closed, and then the drying stage is entered. The specific process of drying is as follows: the air in the oven 1 is heated by the heating mechanism 12 and then introduced into the blowing box 8 through the lifting pump 13. The hot air is blown to several drain baskets through the blowing box 8. At the same time, the swing mechanism drives the rotating shaft 5 to rotate to one side, and the rotation of the rotating shaft 5 drives the supporting bracket 4 to rotate and tilt, so that the drain basket placed on the supporting bracket 4 will be in a tilted state. During this process, the end of the drain basket corresponding to the dial wheel 6 tilts downward. When the drain basket is tilted, the aluminum parts in the drain basket will slide toward the dial wheel 6, and the rotating mechanism will drive The thumbwheel 6 continues to rotate, and the translation mechanism drives the thumbwheel 6 to translate. The translated thumbwheel 6 will face the aluminum parts sliding downward and scatter the aluminum parts by the rotation of the thumbwheel 6. When the thumbwheel 6 translates from the downward end of the drain basket to the upward end of the drain basket, the swing mechanism drives the rotating shaft 5 to rotate in the opposite direction, so that the supporting frame 4 will drive the drain basket to tilt in the opposite direction. When the drain basket tilts in the opposite direction, the thumbwheel 6 will translate from the downward end of the drain basket to the upward end of the drain basket again, and in this process, the thumbwheel 6 will scatter the aluminum parts sliding downward again by self-rotation. In summary, the aluminum parts stored in the drain basket The parts will be dispersed back and forth by the thumbwheel 6 during drying to ensure that the aluminum parts are heated evenly, and the rotation speed of the thumbwheel 6 and the tilting speed of the support bracket 4 are low, so that the aluminum parts will not be damaged by large hard collisions. After the hot air passes through the drain basket, the hot air in the oven 1 is drawn into the condensing mechanism 11 through the return air box 9 by the exhaust mechanism 10. At this time, the water vapor in the hot air is precipitated through the condensing mechanism 11 and condensed into free water. The hot air dried by the condensing mechanism 11 will enter the heating mechanism 12 for reheating. Finally, the reheated hot air will be introduced into the blowing box 8 through the lifting pump 13 and blown into the oven 1 again.

[0047] In order to show the specific structure of the support bracket 4 and the thumbwheel 6, the following features are set:

[0048] Each support bracket 4 includes a support plate 14 and two limit bars 15. The support plate 14 is horizontal. The two limit bars 15 are respectively arranged at both ends of the support plate 14. Each limit bar 15 is vertically fixed to the end of the support plate 14. The support plate 14 is provided with a plurality of vents 16 (such as Fig.10As shown in the figure, each thumbwheel 6 includes a central axis 17, two circular baffles 18 and a plurality of shovel plates 19. The central axis 17 is horizontal. The two circular baffles 18 are respectively arranged at the two ends of the central axis 17. Each circular baffle 18 is coaxially fixed to the end of the central axis 17. The plurality of shovel plates 19 are evenly distributed along the circumferential direction of the central axis 17. Each shovel plate 19 is arranged between the two circular baffles 18, and each shovel plate 19 is fixed to the central axis 17. The outer side of each circular baffle 18 is coaxially formed with an end shaft 20, and each end shaft 20 is rotatably connected to the slider 7.

[0049] When the drain basket is placed on the support frame 4, the drain basket is placed downward on the support plate 14, and when the support frame 4 is tilted back and forth, two limit bars 15 are used to prevent the drain basket from sliding off the support plate 14, and a plurality of vents 16 on the support plate 14 allow the hot air in the oven 1 to pass through the support plate 14 and act on the drain basket;

[0050] The entire thumbwheel 6 rotates through the end shaft 20 provided on the two circular baffles 18. When the thumbwheel 6 rotates, the aluminum parts in the drain basket will slide toward the thumbwheel 6 due to the inclined state of the drain basket. At this time, the aluminum parts in the drain basket are scooped up by the shovel plate 19 provided on the central axis 17, and the scooped aluminum parts will be temporarily stored between the two shovel plates 19. Thereafter, as the thumbwheel 6 rotates, the aluminum parts temporarily stored between the two shovel plates 19 will slide down and fall into the drain basket again, thereby dispersing the aluminum parts in the drain basket through the reciprocating translation and self-rotating thumbwheel 6, thereby ensuring that the aluminum parts are heated evenly.

[0051] In order to show the specific structure of the translation mechanism, the following features are set:

[0052] The translation mechanism includes several groups of screw drive members corresponding to the support bracket 4, each group of screw drive members includes a threaded rod 21, a driving block 22, two limit shafts 23 and two guide blocks 24, the threaded rod 21 rotates horizontally at the bottom of the support plate 14, the two limit shafts 23 are respectively arranged on both sides of the threaded rod 21, and each limit shaft 23 is parallel to the threaded rod 21, the threaded rod 21 passes through the driving block 22, and the driving block 22 is threadedly matched with the threaded rod 21, the two limit shafts 23 respectively pass through the two guide blocks 24, and the two guide blocks 24 are connected to the driving block 22 through a connecting block 25, each guide block 24 is fixed with a vertical upward strip seat 26, a vertical slide groove 27 is arranged in the strip seat 26, each slider 7 slides in the slide groove 27, a limit block 28 is fixed at the lower end of the slide groove 27, and each elastic member is arranged at the upper end of the slide groove 27, and a driving mechanism for driving several threaded rods 21 to rotate synchronously is provided in the oven 1.

[0053] Since the driving block 22 is threadedly matched with the threaded rod 21, when the driving mechanism drives several threaded rods 21 to rotate, each driving block 22 will drive the guide blocks 24 on both sides to slide, so that the bar seat 26 connected to the guide blocks 24 will be driven to translate synchronously, and the translation direction of the bar seat 26 is consistent with the axial direction of the limit shaft 23. When the bar seat 26 translates, the slider 7 arranged in the slide groove 27 will move together with the bar seat 26, and finally the entire dial wheel 6 will be driven to translate through the two sliders 7, wherein each elastic member will press the slider 7 toward the limit block 28 through the elastic force, and then the limit block 28 will be used to limit the descending stroke of the slider 7 to ensure that the dial wheel 6 will not collide with the bottom wall of the drain basket and affect the rotation of the dial wheel 6.

[0054] In order to show the specific structure of the drive mechanism, the following features are set:

[0055] The driving mechanism includes a reduction motor 29, a main drive shaft 30 and a plurality of transmission shafts 31. The transmission shafts 31 correspond to the threaded rods 21 one by one. Each transmission shaft 31 rotates on the inner wall of the oven 1 away from the outlet. A universal coupling 32 is provided between each transmission shaft 31 and the corresponding threaded rod 21 to connect the two. A No. 1 synchronous transmission member is provided between adjacent transmission shafts 31. The No. 1 synchronous transmission member includes a No. 1 synchronous belt 33 and two No. 1 synchronous wheels 34. The two No. 1 synchronous wheels 34 are respectively coaxially fixed to the corresponding two transmission shafts 31. A No. 1 synchronous belt 33 is sleeved on two No. 1 synchronous wheels 34, a reduction motor 29 is fixedly arranged outside the oven 1, a main drive shaft 30 is rotatably arranged inside the oven 1, and the reduction motor 29 is used to drive the main drive shaft 30 to rotate. A No. 2 synchronous transmission member is arranged between the main drive shaft 30 and its adjacent transmission shaft 31. The No. 2 synchronous transmission member includes a No. 2 synchronous belt 35 and two No. 2 synchronous wheels 36. The two No. 2 synchronous wheels 36 are respectively coaxially fixedly connected with the main drive shaft 30 and the corresponding transmission shaft 31, and the No. 2 synchronous belt 35 is sleeved on the two No. 2 synchronous wheels 36.

[0056] When the reduction motor 29 is started, the main drive shaft 30 will drive the corresponding transmission shaft 31 to rotate through the transmission action of the No. 2 synchronous belt 35 and the No. 2 synchronous wheel 36. When the transmission shaft 31 connected to the main drive shaft 30 rotates, through the transmission action of the No. 1 synchronous belt 33 and the No. 1 synchronous wheel 34, all the transmission shafts 31 will be synchronously driven, so that each transmission shaft 31 will drive the corresponding threaded rod 21 to rotate through the corresponding universal coupling 32, and finally realize the translation of the thumbwheel 6. Among them, when the support bracket 4 is tilted, through the action of the universal coupling 32, the threaded rod 21 and the corresponding transmission shaft 31 will always remain connected, so that when the support bracket 4 is tilted, it will not affect the rotation of the threaded rod 21.

[0057] In order to show the specific structure of the swing mechanism, the following features are set:

[0058] Each rotating shaft 5 is fixed to the bottom of the support plate 14, and each supporting bracket 4 is provided with a supporting arm 37 fixedly connected to the oven 1 on both sides. The two ends of each rotating shaft 5 are rotatably connected to the two supporting arms 37 respectively. The swing mechanism includes two groups of pneumatic connecting rods respectively arranged on both sides of the supporting bracket 4, and each group of pneumatic connecting rods includes two cylinders 38, two vertical rods 39 and a plurality of horizontal rods 40 (such as Fig.11 As shown in the figure, the cross bars 40 correspond to the rotating shafts 5 one by one, the middle part of each cross bar 40 is fixed on the corresponding rotating shaft 5, both ends of each cross bar 40 are sleeved with telescopic sleeves 41, two vertical rods 39 are respectively arranged at both ends of the cross bar 40, one end of each telescopic sleeve 41 is hinged to the corresponding vertical rod 39, the cylinders 38 correspond to the vertical rods 39 one by one, each cylinder 38 is fixedly arranged directly below the corresponding vertical rod 39, and the output end of each cylinder 38 is fixedly connected to the lower end of the vertical rod 39 upward.

[0059] The swing mechanism contains four cylinders 38 in total. Fig.11 The two cylinders 38 shown in the figure have opposite movement states. When the output end of one of the cylinders 38 rises, the output end of the other cylinder 38 falls, and the corresponding two vertical rods 39 rise and fall respectively. Then, through the drive of the two vertical rods 39, the cross bar 40 placed between the two vertical rods 39 will be driven to rotate. When the cross bar 40 rotates, the cross bar 40 will drive the rotating shaft 5 to rotate, thereby driving the corresponding supporting frame 4 to rotate through the rotating shaft 5, and finally making the supporting frame 4 tilted. When the two vertical rods 39 are lifted and lowered respectively, each cross bar 40 will gradually rotate from a horizontal state to a tilted state. During this process, each telescopic sleeve 41 will gradually extend to cooperate with the lifting and lowering of the two vertical rods 39.

[0062] The slider 7 is pressed down by the elastic force of the spring 46, so that the No. 1 gear 42 connected to the end shaft 20 is meshed downward with the No. 2 gear 43. When the thumbwheel 6 translates, the limit block 28 drives the No. 2 gear 43 to translate on the rack 44. Since the No. 2 gear 43 is meshed with the rack 44, the No. 2 gear 43 will rotate during the translation process. When the No. 2 gear 43 rotates, the No. 1 gear 43 drives the No. 1 gear 42 to rotate, and finally drives the entire thumbwheel 6 to rotate through the No. 1 gear 42, wherein the No. 2 gear 43 plays a reversing role, combined with the No. 1 gear 42.

[0075] Working principle:

[0076] This device is used to dry small aluminum parts. The small aluminum parts need to be washed with water after manufacturing. The washed small aluminum parts are stacked in a drain basket. When drying, several drain baskets are placed on the corresponding support frame 4 in turn. In this process, the drain basket is first tilted, and the aluminum parts in the drain basket are put aside to ensure that there is an empty area in the drain basket. Before placing the drain basket, lift the dial wheel 6, and then place the drain basket flat on the support frame 4. When the drain basket is placed on the support frame 4, release the dial wheel 6, and press the dial wheel 6 down to the empty area in the drain basket through the elastic member. In summary, place After each drain basket is set, the sealing door 2 is closed, and then the drying stage is entered. The specific process of drying is as follows: the air in the oven 1 is heated by the heating mechanism 12 and then introduced into the blowing box 8 through the lifting pump 13. The hot air is blown to several drain baskets through the blowing box 8. At the same time, the swing mechanism drives the rotating shaft 5 to rotate to one side, and the rotation of the rotating shaft 5 drives the supporting bracket 4 to rotate and tilt, so that the drain basket placed on the supporting bracket 4 will be in a tilted state. During this process, the end of the drain basket corresponding to the dial wheel 6 tilts downward. When the drain basket is tilted, the aluminum parts in the drain basket will slide toward the dial wheel 6, and the rotating mechanism will drive The thumbwheel 6 continues to rotate, and the translation mechanism drives the thumbwheel 6 to translate. The translated thumbwheel 6 will face the aluminum parts sliding downward and scatter the aluminum parts by the rotation of the thumbwheel 6. When the thumbwheel 6 translates from the downward end of the drain basket to the upward end of the drain basket, the swing mechanism drives the rotating shaft 5 to rotate in the opposite direction, so that the supporting frame 4 will drive the drain basket to tilt in the opposite direction. When the drain basket tilts in the opposite direction, the thumbwheel 6 will translate from the downward end of the drain basket to the upward end of the drain basket again, and in this process, the thumbwheel 6 will scatter the aluminum parts sliding downward again by self-rotation. In summary, the aluminum parts stored in the drain basket The parts will be dispersed back and forth by the thumbwheel 6 during drying to ensure that the aluminum parts are heated evenly, and the rotation speed of the thumbwheel 6 and the tilting speed of the support bracket 4 are low, so that the aluminum parts will not be damaged by large hard collisions. After the hot air passes through the drain basket, the hot air in the oven 1 is drawn into the condensing mechanism 11 through the return air box 9 by the exhaust mechanism 10. At this time, the water vapor in the hot air is precipitated through the condensing mechanism 11 and condensed into free water. The hot air dried by the condensing mechanism 11 will enter the heating mechanism 12 for reheating. Finally, the reheated hot air will be introduced into the blowing box 8 through the lifting pump 13 and blown into the oven 1 again.
