Description

Technical Field

[0001] This utility model relates to the field of refrigerated dryer technology, and in particular to a refrigerated dryer mixing and processing equipment. Background Technology

[0002] Refrigerated dryers lower the temperature of compressed air through a refrigeration system, causing water vapor to condense and precipitate, thus achieving efficient dehumidification. Core components include a compressor, condenser, evaporator, and air-water separator. The dew point of the treated air typically reaches 2-10℃. They are characterized by low energy consumption and simple maintenance, and are widely used in industries such as electronics, pharmaceuticals, and food to ensure the drying needs of pneumatic systems and production processes.

[0003] Freeze dryers are commonly used for freeze-drying processing. When freeze-drying samples, the inside of the dryer is filled with the residual odor of the sample, and the gas remains inside the plexiglass cover. This causes the odor to adhere to both the plexiglass cover and the dryer cavity. The odor continues to be released when the plexiglass cover is opened, requiring manual cleaning by staff after each use. This also affects the progress of each freeze-drying process, prolongs the processing time, and increases the workload.

[0004] To address this, we designed a freeze dryer mixing and processing equipment. Utility Model Content

[0005] The purpose of this invention is to provide a freeze dryer mixing and processing equipment to solve the problem of improper odor removal in existing technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A freeze dryer mixing and processing device includes a device body, a first heat dissipation grid disposed on the device body, second heat dissipation grids symmetrically disposed on the side wall of the device body, a sample placement chamber disposed on the top of the device body, a sample placement rack disposed in the sample placement chamber, and a start button disposed on the side wall of the device body, and further includes:

[0008] An odor processing assembly includes a fixed plate mounted on the device body, an air extraction assembly mounted on the fixed plate, a purifier mounted on the fixed plate, an outlet mounted on the purifier, a second circulation pipe mounted on the outlet, a second air pump pipe mounted on the second circulation pipe, and a filter assembly mounted on the second air pump pipe.

[0009] Preferably, the air extraction assembly includes a first circulation pipe disposed on a fixed plate, a polymerization pipe disposed on the fixed plate, a first air pump pipe symmetrically disposed at both ends of the polymerization pipe, and a collection pipe symmetrically disposed on the inner wall of the sample release chamber.

[0010] Preferably, the first circulation pipe is connected to the purifier, the polymer pipe is fixed to the first circulation pipe by welding, and the first air pump pipe passes through the device body and is connected to the collection pipe.

[0011] Preferably, the outlet end is connected to the purifier via a fastener, the outlet end is fixed to the second circulation pipe, and the second air pump pipe is fixed to the second circulation pipe.

[0012] Preferably, the filter assembly includes a filter head disposed on the second air pump pipe and a third circulation pipe disposed at the top of the filter head.

[0013] Preferably, the filter head is provided with a first telescopic head and a second telescopic head for extending its length, the filter head is provided with a first bracket and a second bracket, and the filter head is provided with a plurality of fixing blocks.

[0014] Preferably, the first support is provided with a first filter screen, the second support is provided with a second filter screen, and the inner wall of the filter head is provided with multiple activated carbon packets.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model, through the setting of a purifier and a filter head, allows the odor generated during freeze-drying to enter the purifier through a collection tube after the sample is placed on the sample rack. Under the operation of the second air pump tube, the odor enters the filter head, which performs preliminary filtration. The odor is then diluted by multiple activated carbon packs, and finally the purified gas is discharged through the exhaust pipe. This reduces the odor adhering to the device body and the inner wall of the plexiglass cover, thus reducing the frequency of subsequent cleaning by the staff.

[0017] 2. By setting up the aggregation tube and the first air pump tube, when the gas is drawn in by the collection tube, it can be uniformly gathered at the aggregation tube under the operation of the first air pump tube. Then, through the input power of the second air pump tube, it flows in the first circulation tube and reaches the outlet end on one side of the purifier. During the transportation process, it can avoid the odor from adhering to the inside of the purifier and the fixed plate, further reducing the cleaning frequency of both, thereby improving the odor cleaning efficiency.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-6 A freeze dryer mixing and processing device includes a device body 1, a first heat dissipation grille 101 disposed on the device body 1, second heat dissipation grilles 102 symmetrically disposed on the side wall of the device body 1, a sample placement chamber 103 disposed on the top of the device body 1, a sample placement rack 104 disposed in the sample placement chamber 103, and a start button 105 disposed on the side wall of the device body 1. It also includes an odor processing component, which mainly performs odor removal on the sample placement chamber 103 and the sample placement rack 104 on the device body 1, avoiding the need for manual cleaning each time the device body 1 is used.

[0027] Before using the device body 1, the device body 1 needs to be inspected. Then, the first heat dissipation grid 101 and the second heat dissipation grid 102 are inspected to ensure that the device body 1 can dissipate heat normally. Then, the sample placement chamber 103 and the sample placement rack 104 are inspected to ensure that there are no objects attached to their surfaces that would affect the freeze-drying process of the samples. The start button 105 on one side of the device body 1 is also inspected to ensure that the device body 1 can be started normally.

[0028] It should be noted that the device body 1, the first heat dissipation grille 101, the second heat dissipation grille 102, the sample placement chamber 103, the sample placement rack 104, and the start button 105 are all existing freeze dryers and functional components.

[0029] Specifically, the odor processing component includes a fixed plate 2 disposed on the device body 1, an air extraction component disposed on the fixed plate 2, a purifier 3 disposed on the fixed plate 2, an outlet 301 disposed on the purifier 3, a second circulation pipe 302 disposed on the outlet 301, a second air pump pipe 303 disposed on the second circulation pipe 302, and a filter component disposed on the second air pump pipe 303.

[0030] When the air extraction component draws the odor-laden gas from the device body 1 into the purifier 3, the gas will enter the second circulation pipe 302 from the outlet 301. The second air pump pipe 303 on the second circulation pipe 302 can improve the gas delivery efficiency. The gas will then enter the filter component under the delivery of the second air pump pipe 303. The filter component can filter the odor in the gas and discharge it from the purifier 3 after filtration and purification.

[0031] It should be noted that the second air pump pipe 303 is existing technology. The pipe body is equipped with a pipe body component for the air pump, and the air pump needs to be driven by an external power source. The multiple fixing nuts 306 on the second air pump pipe 303 are auxiliary components. Corresponding threads need to be opened on the second air pump pipe 303 so that the fixing nuts 306 can be connected to the second air pump pipe 303 through the threaded connection.

[0032] Purifier 3 is an air purifier in the existing technology, which centrally purifies and discharges gas.

[0033] The air extraction assembly includes a first circulation pipe 201 disposed on the fixed plate 2, a polymerization pipe 202 disposed on the fixed plate 2, a first air pump pipe 203 symmetrically disposed at both ends of the polymerization pipe 202, and a collection pipe 106 symmetrically disposed on the inner wall of the sample release chamber 103.

[0034] The first circulation pipe 201 is connected to the purifier 3, the polymer pipe 202 is fixed to the first circulation pipe 201 by welding, and the first air pump pipe 203 passes through the device body 1 and is connected to the collection pipe 106.

[0035] When the device body 1 processes the sample, the first air pump pipe 203 is activated to form a gas vortex in the sample dispensing chamber 103. The odor emitted by the sample is drawn into the gas vortex and then collected at the aggregation pipe 202 through the first air pump pipe 203. From the aggregation pipe 202, it enters the first circulation pipe 201. The bend in the first circulation pipe 201 can increase the internal pressure and reduce the gas residue, so that the gas can quickly enter the purifier 3 under the drive of the air pressure.

[0036] The first circulation pipe 201 is fixed to the fixing plate 2 by welding, and one end is connected to the inlet of the purifier 3, while the other end is connected to the aggregation pipe 202 by welding to ensure connectivity. The first air pump pipe 203 needs to be extended into the inside of the device body 1 through the auxiliary pipe and connected to the collection pipe 106.

[0037] It should be noted that the first air pump pipe 203 is existing technology, with a pipe body component for the air pump attached to the pipe body, and the air pump needs to be driven by an external power source.

[0038] The lead-out end 301 is connected to the purifier 3 via a fastener, and the lead-out end 301 is fixed to the second circulation pipe 302. The second air pump pipe 303 is fixed to the second circulation pipe 302.

[0039] The outlet end 301 is a tracheal connection end body in the prior art, which can effectively reduce gas leakage. The fastener here is a ring fastener commonly used in tracheal connection end bodies. The second air pump pipe 303 is connected to the second circulation pipe 302 through the ring fastener.

[0040] The filter assembly includes a filter head 304 disposed on the second air pump pipe 303 and a third circulation pipe 305 disposed at the top of the filter head 304.

[0041] The filter head 304 is provided with a first telescopic head 4 and a second telescopic head 401 for extending the length. The filter head 304 is provided with a first bracket 403 and a second bracket 405, and a plurality of fixing blocks 407 are provided inside the filter head 304.

[0042] The first support 403 is provided with a first filter screen 404, the second support 405 is provided with a second filter screen 406, and the inner wall of the filter head 304 is provided with multiple activated carbon packs 408.

[0043] When the gas enters the filter head 304 through the second air pump pipe 303, it will be directly filtered and enter the third circulation pipe 305. The gas is then transported to the exhaust pipe 308 in the inner groove 307 at the bottom of the purifier 3 through the third circulation pipe 305, and discharged uniformly by the exhaust pipe 308. The heat insulation body 309 on both sides of the exhaust pipe 308 is used to reduce the pipe breakage caused by temperature difference. At the same time, the limiting rods 204 symmetrically arranged on the side wall of the fixing plate 2 can be used to place commonly used utensils.

[0044] Before the gas enters the filter head 304, the filter head 304 can be adjusted by moving the first telescopic head 4 and the second telescopic head 401 to extend it. While extending it, ensure that the connecting end 402 can be properly connected to the third circulation pipe 305. When the gas enters the filter head 304, it will first be pre-filtered by the first filter screen 404 and the second filter screen 406 to reduce the movement of dust. After the gas passes through, it will be surrounded by the activated carbon pack 408, which will completely absorb the odor and purify the gas before it is discharged into the third circulation pipe 305.

[0045] The first filter screen 404 and the second filter screen 406 are fixed inside the filter head 304 by the first bracket 403 and the second bracket 405, while the activated carbon pack 408 is tied to the inner wall of the filter head 304 by fasteners, and the fixing block 407 is used to help correct the direction of the gas.

[0046] The working principle of this utility model is as follows:

[0047] After the staff places the sample on the sample rack 104, they can press the start button 105 after covering it with the plexiglass cover. The odorous gas generated by the device body 1 during operation will be drawn in by the collection pipe 106. The gas enters the purifier 3 through the first air pump 203, the aggregation pipe 202 and the first circulation pipe 201. Then the gas enters the second circulation pipe 302 from the outlet 301, and then enters the second air pump pipe 303 through the second circulation pipe 302. The air pump increases the efficiency of the gas entering the filter head 304. The filter head 304 performs unified filtration and purification of the gas. Finally, the gas enters the exhaust pipe 308 through the third circulation pipe 305 and is discharged from the purifier 3 through the exhaust pipe 308. With the setup of purifier 3 and filter head 304, when the staff places the sample on the sample rack 104 for freeze-drying, the odor generated by freeze-drying will enter the purifier 3 through the collection pipe 106, and then enter the filter head 304 under the operation of the second air pump pipe 303. The filter head 304 can perform preliminary filtration of the odor, and then dilute the odor through multiple activated carbon packs 408. Finally, the purified gas is discharged through the exhaust pipe 309, thereby reducing the odor adhering to the device body 1 and the inner wall of the plexiglass cover, and reducing the frequency of subsequent cleaning by the staff.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
