Description

TECHNICAL FIELD

[0001] The utility model relates to freeze drying equipment technical field, especially freeze drying machine's supporting storage rack. BACKGROUND

[0002] Freeze drying machine is a kind of equipment that material is frozen at low temperature and the moisture in it is directly sublimated under vacuum condition to realize drying, can retain the nutrient component, biological activity and physical and chemical properties of material to the greatest extent;The material after drying is porous and loose, and the rehydration is good, and can quickly recover to the state before drying;Drying under low temperature and vacuum environment can avoid oxidation, metamorphic and microbial contamination of material, prolongs the shelf life of material;Wide range of adaptation, can handle various different properties and forms of material.Therefore, it is widely used in biological medicine, food processing, chemical industry and other technical fields.

[0003] The cold space of the upper part of the existing small freeze drying machine is small, when the material to be frozen is too much, batch freezing is needed, and the freezing time is long;And purchasing large freeze drying machine is expensive, causing high production cost.Therefore, the Chinese patent with patent number 202322830941.5 discloses a freeze drying machine, which designs a freezing storage rack to expand the upper space, and is equipped with a protective cover to keep the upper freezing space relatively closed;At the same time, a rotating mechanism is arranged to keep the material uniformly freeze dried;But since the freezing storage rack needs to rotate during use, to ensure the stability of the storage rack, the trays of the storage rack are usually welded with the support;Due to the limited space between the trays, it is very inconvenient to take the material from the remaining trays of the storage rack except the top tray. UTILITY MODEL CONTENTS

[0004] In view of the deficiencies of the prior art, the technical problem solved by the utility model is to provide a freeze drying machine's supporting storage rack, which solves the problem that the existing freezing storage rack needs to rotate during use, and the trays of the storage rack are usually welded with the support, making it very inconvenient to take and place the material from the storage rack.

[0005] To solve the above problems, the technical solution adopted by this utility model is: a shelf for a freeze dryer, including a support, a tray, and a protective cover. The support includes two vertically arranged columns and multiple connecting rods spaced apart between the two columns. A support limiting plate is provided in the middle of the connecting rods. The support limiting plate has mutually perpendicular sliding grooves and limiting grooves. Both the limiting grooves and the sliding grooves are T-shaped grooves. The sliding grooves and limiting grooves form a cross shape, and the intersection of the two grooves is located at the center of the connecting rod. The two ends of the sliding grooves extend to the support limiting plate. On the edge of the plate, the sliding groove near the limiting groove has a limiting hole on the side wall of the groove along the direction of the limiting groove. The limiting hole is provided with a limiting spring and a limiting component in sequence from the inside to the outside. The tray has multiple corresponding connecting rods. The bottom center of the tray has a T-shaped slider composed of a vertical rod and a horizontal block, which corresponds to the T-shaped groove. Both sides of the horizontal block have a receiving cavity. The receiving cavity is provided with a wedge-shaped locking block. A locking spring is provided between the locking block and the receiving cavity. When the T-shaped slider is in the sliding groove, the wedge-shaped locking block is completely limited in the receiving cavity. When the T-shaped slider is in the limiting groove, the wedge-shaped locking block pops out and is limited.

[0006] The beneficial effects of this solution are as follows: When using the device, operators only need to slide the tray onto the support limiting plate along the inlet section. After freeze-drying is complete, the tray can be slid out along the outlet section, allowing for quick loading and unloading between the tray and the support. This facilitates the process of placing the material to be dried on the tray first, then sliding the tray to the limiting groove. The cooperation of the locking block and the limiting component keeps the horizontal block within the limiting groove, ensuring the stability of the tray connection. Secondly, the use of sliding or pulling to connect the tray to the support limiting plate makes the installation and disassembly process smoother, thus preventing the material on the tray from shifting.

[0007] Furthermore, the column adopts a threaded rod, and the connecting rod is slidably connected to the column. The column is equipped with at least two limiting bolts, which are respectively located at the upper and lower ends of the lower connecting rod. Through the cooperation of the threaded rod and the limiting bolts, the position of the tray can be adjusted by adjusting the position of the limiting bolts, facilitating the adjustment of the spacing between trays according to different usage requirements.

[0008] Furthermore, the limiting component is a limiting rod, the end of which is an inclined surface that cooperates with the wedge-shaped locking block. The wedge-shaped inclined surface facilitates the removal of the T-shaped slider from the limiting groove into the sliding groove under external force.

[0009] Furthermore, the limiting mechanism employs limiting beads. Compared to other complex limiting structures, the design and manufacturing process of using limiting beads is relatively simple, and it is also more convenient and quick to install and use, as well as easier to maintain and replace.

[0010] Further, the support limiting plate is circular or square. Circular or square structure is easy to process, and the circular structure can make the support of the tray more uniform.

[0011] Further, the width or length of the support limiting plate is less than half of the length of the connecting rod. By limiting the size of the support limiting plate, the contact area of the support limiting plate with the tray is controlled, so as to avoid affecting the freeze-drying effect of the materials in the tray; at the same time, the small-area support limiting plate has lower manufacturing cost.

[0016] The following will be further described in detail through specific embodiments:

[0017] The reference signs in the drawings of the specification include: support 1, column 11, limiting bolt 112, connecting rod 12, support limiting plate 13, sliding groove 14, inlet section 141, outlet section 142, limiting hole 143, limiting piece 144, limiting spring 145, limiting groove 15, tray 2, cross block 21, clamping block 211, containing cavity 212, clamping spring 213.

[0018] Example 1 is basically as shown in the accompanying drawings Figures 1-3As shown: a freeze dryer supporting shelf, including support 1, tray 2 and protective cover, the support 1 includes two vertical columns 11 arranged in vertical direction, and a plurality of connecting rods 12 arranged between the two vertical columns 11, the connecting rod 12 is provided with support limiting plate 13 in the middle, the support limiting plate 13 is provided with sliding groove 14 and limiting groove 15 arranged perpendicularly to each other, the limiting groove 15 and the sliding groove 14 are both T-shaped grooves; the sliding groove 14 and the limiting groove 15 form a cross type and the intersection of the two grooves is located at the center of the connecting rod 12, the sliding groove 14 extends to the edge of the support limiting plate 13 at both ends, the sliding groove 14 includes inlet section 141 and outlet section 142 arranged at both ends of the limiting groove 15, the outlet section 142 is close to the groove side wall of the limiting groove 15 and opens limiting hole 143 in the direction of the limiting groove 15, the limiting hole 143 is sequentially provided with limiting spring 145 and limiting piece 144 from inside to outside, and the limiting adopts limiting ball; the tray 2 is provided with a plurality of corresponding connecting rods 12, and the bottom center of the tray 2 is provided with T-shaped sliding block composed of vertical rod and cross block 21 and corresponding to the T-shaped groove; as shown, Figure 3 the cross block 21 is provided with wedge-shaped clamping block 211 in the containing cavity 212, and the clamping block 211 is provided with clamping spring 213 between the containing cavity 212; as shown, Figure 2 when the T-shaped sliding block is located in the sliding groove 14, the wedge-shaped clamping block 211 is limited in the containing cavity 212, and when the T-shaped sliding block is located in the limiting groove 15, the wedge-shaped clamping block 211 is popped out into the limiting groove 15.

[0019] The vertical column 11 adopts threaded rod, the connecting rod 12 is slidingly connected with the vertical column 11, the vertical column 11 is provided with limiting bolt 112, the limiting bolt 112 is provided with at least two, which are arranged on the upper and lower ends of the lower connecting rod 12 respectively. Through the cooperation of the threaded rod and the limiting bolt 112, the position of the tray 2 is adjusted by adjusting the position of the limiting bolt 112, so as to facilitate the adjustment of the distance between the trays 2 according to different use requirements.

[0020] The support limiting plate 13 is circular, and the diameter of the support limiting plate 13 is one third of the length of the connecting rod 12.

[0021] In use, the material to be freeze-dried is placed on the tray 2, the T-shaped block at the bottom of the tray 2 is butted against the sliding groove 14, so that the wedge-shaped clamping block 211 of the transverse block is pressed into the accommodating cavity 212, so that the T-shaped block can be smoothly slid from the inlet section 141 into the limiting groove 15, and when entering the limiting groove 15, the clamping block 211 is popped out under the elastic force of the clamping spring 213 because the two sides of the transverse block are no longer limited, so that the transverse block is limited in the limiting groove 15, so that the tray 2 cannot slide off the support limiting plate 13; when the support 1 rotates with the rotating disc of the freeze-drying machine, the tray 2 rotates with the support 1 due to the limiting of the clamping block 211. After the freeze-drying is completed, the tray 2 is pulled out of the sliding groove 14 from the outlet section 142, and when the transverse block 21 starts to enter the outlet section 142 under the action of external force, the front end of the clamping block 211 presses the limiting ball into the limiting hole 143, so that the transverse block 21 is no longer limited, and when the transverse block 21 moves into the outlet section 142 step by step, the wedge-shaped clamping block 211 is gradually compressed into the accommodating cavity 212 by the side wall of the groove body.

[0022] In use, the operator only needs to install the tray 2 on the support limiting plate 13 in a sliding manner along the inlet section 141, and then pull out the tray 2 along the outlet section 142 in a sliding manner after the freeze-drying is completed, so that the loading and unloading between the tray 2 and the support 1 can be quickly completed; so that the operator can first place the material to be dried on the tray 2, and then slide the tray 2 to the limiting groove 15, and limit the transverse block 21 in the limiting groove 15 through the cooperation of the clamping block 211 and the limiting piece 144, so as to ensure the stability of the connection of the tray 2; secondly, the connection between the tray 2 and the support limiting plate 13 is realized in a sliding or pulling manner, so that the installation and disassembly process is more stable, so that the material on the tray 2 is not easy to move.

[0023] The same as in example 1 will not be repeated, and the difference is that the support limiting plate 13 is square; the width or length of the support limiting plate 13 is five fifths of the length of the connecting rod 12.

[0024] The limiting piece 144 is a limiting rod, and the end of the limiting rod is a slope matched with the wedge-shaped clamping block 211. The wedge-shaped slope facilitates the pushing of the T-shaped block out of the limiting groove 15 to the sliding groove 14 under the action of external force.
