Description

Technical Field

[0001] The present application relates to the technical field of dirt cleaning, and in particular to a cleaning mechanism of a freeze dryer. Background Art

[0002] A freeze dryer, also known as a lyophilizer, is a device used to freeze food and remove its moisture through a sublimation process. Freeze drying technology originated in the early 20th century. The first freeze dryer was invented in 1906 and was used to freeze-dry plasma. Since then, this technology has gradually been applied to food, medicine, and cosmetics. Over the past century, freeze drying technology has undergone continuous improvement and development and has been widely used in food processing.

[0003] After the freeze dryer is used, residues and debris often remain inside. Since the freeze-dried products need to be placed in a tray and sent to the freeze drying box for freeze drying, a slide groove for the tray to slide and engage is provided in the freeze drying box. The residues and debris are easily stuck in the slide groove, and there is a corner at the connection between the slide groove and the inner wall of the freeze drying box. The residues and debris remaining here are difficult to clean. In the prior art, when the freeze-dried varieties are changed, when the residues in the freeze drying box are difficult to remove, manual scrubbing is required, which is not only very troublesome to operate, but also because the working temperature in the freeze drying box is very low, it needs to be restored to room temperature for manual cleaning, which will extend the downtime of the freeze dryer, thereby reducing work efficiency.

[0004] For this reason, we propose a cleaning mechanism of a freeze dryer to solve the above problems. Summary of the invention

[0016] Furthermore, the toggle plate is made of rubber, the rotating plate is made of hard plastic, and the toggle plate is in contact with the inner wall of the freeze dryer.

[0017] Furthermore, a flushing assembly is also provided on the mobile base, and the flushing assembly includes a liquid storage tank, a bracket, a nozzle, a hose, a recovery tank, a collection bucket and a connecting pipe;

[0022] Compared with the prior art, the advantages of this application are:

[0023] (1) By setting up a telescopic adjustment component, the device can be telescoped inside the freeze dryer so as to fit the inner wall of the freeze dryer. Before entering the freeze dryer, the magnetic poles of the two electromagnetic blocks in the adjustment cylinder are opposite. Due to the principle of opposite magnetic poles attracting each other, the adjustment slider is attracted together, so that the adjustment slider is in a contracted state. After entering the freeze dryer, the magnetism of the electromagnetic block is changed so that the magnetic poles of the two electromagnetic blocks in the adjustment cylinder are the same. Due to the principle of like magnetic poles repelling each other, the adjustment slider moves away from each other, so that the adjustment slider is in an open state and drives the cleaning component to fit closely with the inner wall of the freeze dryer. The device can also be adapted to freeze dryers of different sizes, making it more adaptable and practical.

[0024] (2) By setting up a fixing component, the device can be fixed after entering the freeze dryer. After entering the freeze dryer, the lifting cylinder drives the device to be lifted as a whole, so that the device is located in the middle position of the freeze dryer. Then the two-way cylinder is started, and the two output ends of the two-way cylinder extend to drive the two suction cups to move, and the suction cups are squeezed with the inner wall and cabinet door of the freeze dryer, so that the two suction cups move and adsorb on the inner wall and cabinet door of the freeze dryer respectively, thereby fixing the device and improving the stability of the cleaning work.

[0025] (3) By setting up a cleaning component, the electric slider can drive the cleaning component to move in the slide rails provided on the adjusting cylinder and the adjusting slider, thereby driving the fixed cleaning brush and the telescopic cleaning brush to move around the inner wall of the freeze dryer to clean it. During the moving cleaning process, when the toggle plate passes through the slide groove, it is squeezed with the slide groove, causing the toggle plate to rotate, thereby driving the rotating plate to rotate downward to press the timing switch. After the timing switch is closed, the controller will control the electric slider to move up and down in the area for a certain period of time, so that the fixed cleaning brush and the telescopic cleaning brush continuously move up and down in the slide groove area to repeatedly brush the slide groove, so that the residue and debris in the slide groove and the corner where the slide groove connects to the inner wall of the freeze dryer can be cleaned more thoroughly.

[0026] (4) By providing a fixed cleaning brush and a telescopic cleaning brush, the telescopic cleaning brush can extend the cleaning length and expand the cleaning area, and the telescopic cleaning brushes at both ends of the fixed cleaning brush can be abutted between the freeze dryer and the cabinet door through the elastic element, so that the fixed cleaning brush and the telescopic cleaning brush can comprehensively clean the inner wall of the entire freeze dryer during cleaning, thereby avoiding cleaning dead corners.

[0027] (5) By providing a toggle plate made of rubber material and a rotating plate made of hard plastic material, when the toggle plate passes through the slide groove, the toggle plate made of rubber material can be deformed so as to continue to move over the slide groove. At the same time, when passing through the slide groove, it will be squeezed between the slide groove, thereby driving the rotating plate to rotate, pressing the timing switch, and performing deep cleaning on the slide groove.

[0028] (6) By setting up a flushing component, during cleaning, the cleaning liquid in the liquid storage tank is pumped out by the suction pump and sprayed on the inner wall of the freeze dryer through the nozzle. On the one hand, the inner wall of the freeze dryer scrubbed by the fixed cleaning brush and the telescopic cleaning brush can be flushed and cleaned. On the other hand, the sprayed cleaning liquid can soak the fixed cleaning brush and the telescopic cleaning brush, making the scrubbing cleaning effect better. The used cleaning liquid flows to the inner bottom of the freeze dryer, and is absorbed by the suction pump through the collection bucket and stored in the recovery box.

[0029] (7) By setting up a transfer component, when the freeze dryer needs to be cleaned, the cleaning mechanism is placed on the tray, the base and the tray are pushed to move through the universal wheels, the cleaning mechanism is transferred to the front of the freeze dryer, the cabinet door is opened, and the height of the tray is adjusted by adjusting the cylinder so that the tray is flush with the inner bottom wall of the freeze dryer, and then the cleaning mechanism is pushed into the freeze dryer for cleaning, which is convenient and quick to operate.

[0030] (8) By arranging balls distributed in an array at the bottom of the movable base, it is possible to facilitate the movement of the cleaning mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Specifically, before entering the freeze dryer 1, the magnetic poles of the two electromagnetic blocks 705 in the adjustment cylinder 703 are opposite. Due to the principle of opposite magnetic poles attracting each other, the adjustment slider 704 will be attracted together, so that the adjustment slider 704 is in a contracted state. After entering the freeze dryer 1, the magnetism of the electromagnetic block 705 is changed so that the magnetic poles of the two electromagnetic blocks 705 in the adjustment cylinder 703 are the same. Due to the principle of like magnetic poles repelling each other, the adjustment slider 704 will move away from each other, so that the adjustment slider 704 is in an open state, and drives the cleaning component 8 to fit closely with the inner wall of the freeze dryer 1, and the device can also adapt to freeze dryers 1 of different sizes, making it more adaptable and practical.

[0047] See also Figure 2-4 A cleaning assembly 8 is provided on the electric slider 706, and the cleaning assembly 8 includes a fixed cleaning brush 801, a telescopic cleaning brush 802, a rotating frame 803, a rotating drum 804, a toggle plate 805, a rotating plate 806, a timing switch 807 and a reset spring 808; the fixed cleaning brush 801 is fixedly connected to the electric slider 706, and two telescopic cleaning brushes 802 are provided and are slidably connected to the two sides of the fixed cleaning brush 801 respectively, and the two telescopic cleaning brushes 802 are connected by an elastic element. The telescopic cleaning brush 802 can extend the cleaning length and expand the cleaning area, and the elastic element can make the telescopic cleaning brushes 802 at both ends of the fixed cleaning brush 801 abut between the freeze dryer 1 and the cabinet door 2, so that the fixed cleaning brush 801 and the telescopic cleaning brush 802 can comprehensively clean the inner wall of the entire freeze dryer 1 during cleaning, and can avoid cleaning dead corners.

[0048] The rotating frame 803 is fixedly connected to the top of the electric slider 706, the rotating drum 804 is rotatably connected to the rotating frame 803, the toggle plate 805 is fixedly connected to the side of the rotating drum 804 close to the fixed cleaning brush 801, the rotating plate 806 is fixedly connected to the side of the rotating drum 804 away from the fixed cleaning brush 801, the timing switch 807 is arranged below the rotating plate 806, and the reset spring 808 is fixedly connected between the rotating plate 806 and the electric slider 706.

[0049] The toggle plate 805 is made of rubber, and the rotating plate 806 is made of hard plastic. The toggle plate 805 fits the inner wall of the freeze dryer 1. When the toggle plate 805 passes through the chute 3, the rubber toggle plate 805 can be deformed so as to continue to move over the chute 3. At the same time, when passing through the chute 3, it will be squeezed between the chute 3, thereby driving the rotating plate 806 to rotate, pressing the timing switch 807, and performing deep cleaning on the chute 3.

[0050] Specifically, the electric slider 706 can drive the cleaning component 8 to move in the slide rails provided on the adjusting cylinder 703 and the adjusting slider 704, thereby driving the fixed cleaning brush 801 and the telescopic cleaning brush 802 to move around the inner wall of the freeze dryer 1 to clean it. During the moving cleaning process, when the toggle plate 805 passes through the slide groove 3, it is squeezed with the slide groove 3, causing the toggle plate 805 to rotate, thereby driving the rotating plate 806 to rotate downward to press the timing switch 807. After the timing switch 807 is closed, the controller will control the electric slider 706 to move up and down in the area for a certain period of time, so that the fixed cleaning brush 801 and the telescopic cleaning brush 802 continuously reciprocate up and down in the area of ​​the slide groove 3 to repeatedly brush the slide groove 3, so that the residue and debris in the slide groove 3 and the corner where the slide groove 3 is connected to the inner wall of the freeze dryer 1 can be cleaned more thoroughly.

[0051] See also Figure 2-4 A flushing assembly 9 is also provided on the mobile base 4, and the flushing assembly 9 includes a liquid storage tank 901, a bracket 902, a nozzle 903, a hose 904, a recovery tank 905, a collecting bucket 906 and a connecting pipe 907; the liquid storage tank 901 is fixedly connected to one end of the top of the mobile base 4, the bracket 902 is fixedly connected to the top of the electric slider 706, the nozzle 903 is fixedly connected to the bracket 902, the hose 904 is fixedly connected between the liquid storage tank 901 and the nozzle 903 to connect the liquid storage tank 901 with the nozzle 903, the recovery tank 905 is fixedly connected to the other end of the top of the mobile base 4, the opening of the collecting bucket 906 faces the inner bottom wall of the freeze dryer 1, and the connecting pipe 907 is fixedly connected between the recovery tank 905 and the collecting bucket 906 to connect the recovery tank 905 with the collecting bucket 906.

[0052] Specifically, a suction pump is provided in the liquid storage tank 901, which is a prior art and is not shown in the figure. During cleaning, the cleaning liquid in the liquid storage tank 901 is extracted by the suction pump and sprayed on the inner wall of the freeze dryer 1 through the nozzle 903. On the one hand, the inner wall of the freeze dryer 1 after being scrubbed by the fixed cleaning brush 801 and the telescopic cleaning brush 802 can be rinsed and cleaned. On the other hand, the sprayed cleaning liquid can soak the fixed cleaning brush 801 and the telescopic cleaning brush 802, so that the scrubbing and cleaning effect is better. The used cleaning liquid flows to the inner bottom of the freeze dryer 1. A suction pump is also provided in the recovery box 905, which is a prior art and is not shown in the figure. The suction pump absorbs the used cleaning liquid through the collecting bucket 906 and stores it in the recovery box 905.

[0053] Working principle: Before entering the freeze dryer 1, the magnetic poles of the two electromagnetic blocks 705 in the adjustment cylinder 703 are opposite. Due to the principle of opposite magnetic poles attracting each other, the adjustment slider 704 is driven to be adsorbed together, so that the adjustment slider 704 is in a contracted state. After entering the freeze dryer 1, the lifting cylinder 5 drives the device to be lifted as a whole, so that the device is located in the middle position of the freeze dryer 1, and then the two-way cylinder 602 is started. The two output ends of the two-way cylinder 602 extend to drive the two suction cups 603 to move, and the suction cups 603 are in contact with the inner wall and cabinet of the freeze dryer 1. The door 2 is squeezed, so that the two suction cups 603 move and adhere to the inner wall of the freeze dryer 1 and the cabinet door 2 respectively, and the device is fixed to improve the stability of the cleaning work. Then, by changing the magnetism of the electromagnetic block 705, the magnetic poles of the two electromagnetic blocks 705 in the adjustment cylinder 703 are the same. Due to the principle that like magnetic poles repel each other, the adjustment sliders 704 will move away from each other, so that the adjustment sliders 704 are in an open state, and the cleaning component 8 is driven to fit closely with the inner wall of the freeze dryer 1. In addition, the device can be adapted to freeze dryers 1 of different sizes, making it more adaptable and practical.

[0054] Then, the electric slider 706 is started to drive the cleaning assembly 8 to move in the slide rails provided on the adjusting cylinder 703 and the adjusting slider 704, thereby driving the fixed cleaning brush 801 and the telescopic cleaning brush 802 to move around the inner wall of the freeze dryer 1 to clean it. During the rotational cleaning process, when the toggle plate 805 passes through the chute 3, it is squeezed with the chute 3, so that the toggle plate 805 rotates, thereby driving the rotating plate 806 to rotate downward to press the timing switch 807. After the timing switch 807 is closed, the controller controls the electric slider 706 to move up and down in the area for a certain period of time, so that the fixed cleaning brush 801 and the telescopic cleaning brush 802 continuously reciprocate up and down in the area of ​​the chute 3 to repeatedly scrub the chute 3, so that the residue and debris in the chute 3 and the corner where the chute 3 is connected to the inner wall of the freeze dryer 1 can be cleaned more cleanly;

[0055] While the cleaning component 8 is cleaning, the cleaning liquid in the liquid storage tank 901 is pumped out by the suction pump and sprayed on the inner wall of the freeze dryer 1 through the nozzle 903. On the one hand, the inner wall of the freeze dryer 1 scrubbed by the fixed cleaning brush 801 and the telescopic cleaning brush 802 can be rinsed and cleaned. On the other hand, the sprayed cleaning liquid can soak the fixed cleaning brush 801 and the telescopic cleaning brush 802, so that the scrubbing and cleaning effect is better. The used cleaning liquid flows to the inner bottom of the freeze dryer 1, and the used cleaning liquid is absorbed by the collection bucket 906 and stored in the recovery box 905 through the operation of the suction pump.

[0056] Example 2: The present invention provides a cleaning mechanism for a freeze dryer 1, see Figure 6-7 On the basis of Example 1, it also includes a transfer component 10, which includes a universal wheel 1001, a base 1002, an adjusting cylinder 1003, a tray 1004 and a telescopic rod 1005; the universal wheel 1001 is fixedly connected to the bottom of the base 1002, the adjusting cylinder 1003 is fixedly connected to the top of the base 1002, the tray 1004 is fixedly connected to the output end of the adjusting cylinder 1003, and the telescopic rod 1005 is fixedly connected between the base 1002 and the tray 1004.

[0057] Working principle: The tray 1004 is used to carry the cleaning mechanism in Example 1. When the freeze dryer 1 needs to be cleaned, the cleaning mechanism is placed on the tray 1004, and the base 1002 and the tray 1004 are pushed to move through the universal wheels 1001. The cleaning mechanism is transported to the front of the freeze dryer 1, and the cabinet door 2 is opened. The height of the tray 1004 is adjusted by adjusting the cylinder 1003 so that the tray 1004 is flush with the inner bottom wall of the freeze dryer 1, and then the cleaning mechanism is pushed into the freeze dryer 1 for cleaning. The operation is convenient and quick.
