Description

Technical Field

[0001] The invention relates to the field of vacuum microwave technology, in particular to vacuum microwave uniform drying equipment. Background Art

[0002] Vacuum microwave drying equipment is a new type of microwave energy application equipment that combines microwave energy technology with high-temperature drying technology. It combines a series of advantages of sterilization and drying, and overcomes the shortcomings of long conventional drying cycle and low efficiency. In the general material drying process, it can improve the work efficiency by 4 to 10 times compared with conventional drying and sterilization methods. It has the advantages of high drying output, good sterilization effect, and low processing cost. However, the existing vacuum microwave drying and sterilization devices still have defects when used, such as:

[0003] 1. When processing peanut-sized granular foods, traditional large-scale microwave drying and sterilization equipment is not convenient to evenly spread them on the conveyor belt of the microwave processing equipment, which leads to the problem of accumulation during the material guiding process, which seriously affects the problem of incomplete drying and sterilization of this type of granular food;

[0004] 2. After the peanut-sized granular food is dried and sterilized, it will be discharged from the right side of the large microwave equipment into the inner side of the feeding frame. Since the temperature of the material and the feeding frame are very high, if the feeding frame is taken out manually, there will be a safety hazard of scalding, so there are certain imperfections;

[0005] Therefore, it is necessary to provide a vacuum microwave uniform drying device to solve the above technical problems. Summary of the invention

[0006] The object of the present invention is to provide a vacuum microwave uniform drying device, which can not only spread the granular food more evenly above the transmission belt of the microwave equipment body through an intermittent driving mechanism and a material guiding mechanism, to further assist the microwave equipment body in drying the granular food evenly, so that the granular food can be dried more thoroughly, and at the same time, under the action of the reciprocating left and right swinging and upward extension of the telescopic push plate, it can also always avoid the clogging of the discharge port on the right side of the feed funnel, resulting in the inability to discharge the material, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a vacuum microwave uniform drying device, comprising a frame, wherein sealing door panels are movably hinged on the left and right sides of the front of the frame, and a microwave device body is arranged on the inside of the frame, a feeding funnel is installed on the upper left side of the inside of the frame, and an intermittent driving mechanism that can intermittently drive the material guiding mechanism is connected below the feeding funnel, a material guiding mechanism that can uniformly guide peanut-sized granular food to the inside of the microwave device body and above the transmission belt is installed at the bottom of the inner side of the feeding funnel, and a cylinder is installed on the left side above the frame, and a hose conveying auger is penetrated through the upper left side of the frame, a storage frame is slidably connected to the right side of the inside of the frame, and a pushing mechanism that can assist in pushing the storage frame and the granular food inside it onto a transfer flatbed cart and avoid manual pulling out is connected to the outside of the frame. ; The intermittent driving mechanism includes an inclined telescopic rod fixed to the left side of the inside of the frame, and the right end of the inclined telescopic rod is movably hinged with a hinge rod, a telescopic spring is connected to the inside of the left side of the inclined telescopic rod, and a half gear is meshed on the right side below the inclined telescopic rod, and a driving shaft is fixed on the inner side of the half gear; the material guiding mechanism includes a driven shaft connected to the lower inner side of the feeding funnel with a bearing, and a transmission gear is welded on the outside of the driven shaft, a roller is also fixed on the outside of the driven shaft, and a telescopic push plate is fixed above the roller, a hinge plate is movably hinged between the telescopic push plates, and an extrusion telescopic rod is connected to the right side of the telescopic push plate; the pushing mechanism includes an oil telescopic rod installed on the front side of the sealing door panel and the right side of the frame, and an oil pipe is penetrated and connected to the end of the oil telescopic rod, and a push rod is slidably connected to the outer side of the upper end of the oil pipe.

[0008] Preferably, a mounting block is fixed at the upper left inside of the frame, and a vacuum tube is connected through the top of the frame.

[0009] Preferably, a discharge plate is movably hinged at the lower right side of the feed hopper, and the lower right side of the discharge plate is movably hinged to the hinge rod.

[0010] Preferably, the telescopic push plate and the roller are in a one-to-one correspondence.

[0011] Preferably, the extrusion telescopic rod and the oil telescopic rod are both arc-shaped.

[0012] Preferably, a baffle is fixed to the bottom of the cylinder via a piston.

[0013] Preferably, the hose conveying auger is inclined.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention is provided with an intermittent driving mechanism and a material guiding mechanism. By utilizing the rotation of the semi-gear, the inclined telescopic rod can be intermittently driven to cooperate with the telescopic spring to intermittently move left and right, thereby driving the transmission gear, the driven shaft, the transmission gear, the roller, the telescopic push plate and the hinge plate on the back of the feeding funnel to turn left and right intermittently at the same time. By utilizing the intermittent turning of the telescopic push plate to the right and left sides, the telescopic push plate can be extended upward in cooperation with the oil inside the telescopic rod and the telescopic push plate, thereby the telescopic push plate can be extended upward, so that the granular food inside the feeding funnel can be transmitted to the outlet on the right side. By utilizing the intermittent contraction of the inclined telescopic rod to the left side, the discharging plate can be pulled back and forth by the hinged rod to shake. Compared with the existing vacuum microwave uniform drying equipment, the granular food can be spread more evenly on the transmission belt of the microwave equipment body to further assist the microwave equipment body in drying the granular food uniformly. At the same time, under the reciprocating left and right swinging and upward extension of the telescopic push plate, the problem of being unable to discharge the material due to clogging of the discharging port on the right side of the feeding funnel can be always avoided.

[0016] 2. The present invention is provided with a pushing mechanism, which utilizes the effect of manually opening the sealed door panel to effectively drive the oil telescopic rod to contract, so that the oil inside the oil telescopic rod cooperates with the oil tube to be squeezed to the inside of the push rod, and then the push rod pushes the storage frame and the granular food inside it directly to the transfer flatbed truck. Compared with the existing vacuum microwave uniform drying equipment, it effectively avoids the problem of manual operation to take it out, which may cause scalding of hands, thereby increasing the overall safety.

[0027] See also Figure 1-4 and Figure 6The intermittent driving mechanism 5 includes an inclined telescopic rod 501 fixed to the left side of the frame 1, and the right end of the inclined telescopic rod 501 is movably hinged with a hinge rod 501a, a telescopic spring 502 is connected to the left side of the inclined telescopic rod 501, and a half gear 503 is meshed on the right side below the inclined telescopic rod 501, and a driving shaft 504 is fixed on the inner side of the half gear 503; the material guiding mechanism 6 includes a driven shaft 601 connected to the lower inner side of the feed funnel 4 by a bearing, and a transmission gear 601a is welded on the outer side of the driven shaft 601, a roller 602 is also fixed on the outer side of the driven shaft 601, and a telescopic push plate 603 is fixed above the roller 602, a hinge plate 603a is movably hinged between the telescopic push plates 603, and the right side of the telescopic push plate 603 is connected to the extrusion telescopic rod 604, A discharge plate 401 is movably hinged at the lower right side of the feed hopper 4, and the lower right side of the discharge plate 401 is movably hinged to the hinge rod 501a, the telescopic push plate 603 is in a one-to-one correspondence with the roller 602, the extrusion telescopic rod 604 and the oil telescopic rod 1001 are both in an arc shape, when peanut-sized granular food is dried and sterilized above the transmission belt of the microwave equipment body 3, the hose conveying auger 8 is first started by the control button to convey the food to the inside of the feed funnel 4, when the granular food inside the feed funnel 4 reaches a certain amount, then the cylinder 7 is started to drive the baffle 701 to block the guide hole inside the mounting block 101 in cooperation with the sealing gasket, and then the sealing door panel 2 is closed, and a vacuum pump is installed on the back of the frame 1, and the vacuum pump is started by the control button at this time, so that the vacuum The tube 102 sucks the air inside the frame 1 and the microwave device body 3, and the existing vacuum pump can also adjust the vacuum pressure inside the frame 1 and the microwave device body 3, and the microwave device body 3 itself has the function of high-temperature sterilization and drying. At this time, the servo motor on the back of the feeding funnel 4 is started to drive the driving shaft 504 to rotate, and the half gear 503 is driven to rotate through the rotation of the driving shaft 504, and at the same time, the meshing inclined telescopic rod 501 above is driven to move left and right intermittently in cooperation with the telescopic spring 502, and the upper right side of the inclined telescopic rod 501 is also in the shape of a rack, thereby driving the transmission gear 601a, the driven shaft 601, the transmission gear 601a, the roller 602, the telescopic push plate 603 and the hinged plate 603a on the back of the feeding funnel 4 to move intermittently at the same time.

[0028] Example 2

[0029] See also Figure 1 and Figure 5 The pushing mechanism 10 includes an oil telescopic rod 1001 installed on the front side of the sealing door panel 2 and the right side of the frame 1, and the end of the oil telescopic rod 1001 is connected with an oil pipe 1002, and the outer side of the upper end of the oil pipe 1002 is slidably connected with a push rod 1003. The sealing door panel 2 is first opened by a staff member. When the sealing door panel 2 is opened, the oil telescopic rod 1001 will be driven to shrink, so that the oil inside the oil telescopic rod 1001 cooperates with the oil pipe 1002 to be squeezed to the inside of the push rod 1003, so that the push rod 1003 can effectively push the storage frame 9 and the granular food inside it. At this time, it is only necessary to manually push the transfer flatbed cart to the front right side of the frame 1 to receive the storage frame 9. The above structure effectively avoids the problem of manual operation to take it out and causing scalding of the hands, thereby increasing the overall safety.

[0030] Working principle: Figure 1-4 and Figure 6As shown, when peanut-sized granular food is dried and sterilized above the transmission belt of the microwave equipment body 3, the hose conveying auger 8 is first started by the control button to convey the food to the inside of the feeding funnel 4. When the granular food inside the feeding funnel 4 reaches a certain amount, the cylinder 7 is then started to drive the baffle 701 to block the guide hole inside the mounting block 101 in conjunction with the sealing gasket, and then the sealing door panel 2 is closed. A vacuum pump is installed on the back of the frame 1. At this time, the vacuum pump is started by the control button, so that the vacuum tube 102 sucks the air inside the frame 1 and the microwave equipment body 3, and the frame can also be vacuumed by the existing vacuum pump. 1 and the vacuum inside the microwave equipment body 3 are used to adjust the pressure, and the microwave equipment body 3 itself has the function of high-temperature sterilization and drying. At this time, the servo motor on the back of the feeding funnel 4 is started to drive the driving shaft 504 to rotate, and the driving shaft 504 rotates to drive the half gear 503 to rotate, and at the same time drives the upper meshing inclined telescopic rod 501 to move left and right intermittently in coordination with the telescopic spring 502. The upper right side of the inclined telescopic rod 501 is also in a rack shape, thereby driving the transmission gear 601a, the driven shaft 601, the transmission gear 601a, the roller 602, the telescopic push plate 603 and the hinge on the back of the feeding funnel 4 The connecting plate 603a is turned left and right intermittently at the same time, and an extrusion telescopic rod 604 is connected to the lower right side of the telescopic push plate 603. When the telescopic push plate 603 is turned to the right, it can cooperate with the extrusion telescopic rod 604 to squeeze the oil inside the telescopic push plate 603 upward, so that the telescopic push plate 603 extends upward and turns to the right at the same time, so that the granular food inside the feeding funnel 4 can be transmitted to the outlet on the right side. When the inclined telescopic rod 501 is retracted to the left, it can also drive the hinged rod 501a at the right end to intermittently pull the discharge plate 401 to reciprocate and open and close, so as to effectively The granular food pushed by the left side transmission is evenly sprinkled on the rotating transmission belt (note: the size of the discharge port at the lower right side of the feed hopper 4 is just large enough to pass peanut-sized granular food). The above structure, through the reciprocating opening and closing shaking state of the discharge plate 401, can not only spread the granular food more evenly on the transmission belt of the microwave equipment body 3, so as to further assist the microwave equipment body 3 in drying the granular food evenly, but also, under the action of the reciprocating left and right swinging and upward extension of the telescopic push plate 603, it can always avoid the problem of the discharge port on the right side of the feed hopper 4 being blocked and causing the inability to discharge the food;

[0031] After the granular food passes through the microwave equipment body 3 in cooperation with the conveyor belt for high-temperature drying and sterilization, it will be introduced into the inner side of the storage frame 9 from the inclined discharge port on the right side, so as to effectively dry and sterilize the peanut-sized granular food. When the storage frame 9 is full of granular food, it is necessary to take out the storage frame 9 and the granular food inside it and stack them. In order to avoid the safety hazard of scalding hands due to manual operation, the operation method is as follows Figure 1 and Figure 5As shown, the sealing door panel 2 is first opened by the staff. When the sealing door panel 2 is opened, the oil telescopic rod 1001 will be driven to shrink, so that the oil inside the oil telescopic rod 1001 cooperates with the oil tube 1002 to be squeezed to the inside of the push rod 1003, so that the push rod 1003 can effectively push the storage frame 9 and the granular food inside it. At this time, it is only necessary to manually push the transfer flatbed cart and place it on the front right side of the frame 1 to receive the storage frame 9. The above structure effectively avoids the problem of manual operation to take it out, which will cause scalding of the hands, thereby increasing the overall safety. This is the working principle of this case, and thus, a series of work is completed.
