Description

Technical Field

[0001] The present disclosure relates to the technical field of freeze-drying emissions, and particularly to a steam-water blocking device for a freeze dryer and a freeze dryer Background Art

[0002] During the air compression process of a freeze dryer, water vapor in the air will condense into liquid water as the pressure increases and the temperature decreases. This water will be further cooled and accumulate into condensate in the condenser of the freeze dryer. If this generated condensate is not discharged in time, it is easy to accumulate inside the equipment, causing corrosion or damage to the internal parts of the freeze dryer, resulting in a shortened service life of the freeze dryer

[0003] For this reason, a drainage device is generally provided in a common freeze dryer. As disclosed in Chinese Patent Document No. CN220443521U, an automatic drainer is provided at the lower end of the separation unit to achieve the drainage of condensate. However, in actual applications, since the automatic drainer directly discharges to the floor drain in the room, and the condensate discharged by the automatic drainer is usually steam-water, that is, steam-water, this causes the floor drain to easily reverse during the discharge of the automatic drainer, resulting in water accumulation or dust in multiple places on the ground, which not only affects the cleanliness of the site, but also the relatively large amount of steam-water discharged each time will submerge some components, affecting the service life of the freeze dryer Utility Model Content

[0004] The purpose of the present disclosure is to overcome the deficiencies in the prior art and provide a steam-water blocking device and a freeze dryer for a freeze dryer that can achieve the blocking and buffered discharge of steam-water, effectively solve the problem of reverse flow of the floor drain during the discharge of the automatic drainer, and is convenient for users to install and clean, and improve the adaptability of the conical buffer hopper to the single-time steam-water discharge of freeze dryers of different specifications

[0006] A steam-water blocking device for a freeze dryer, the steam-water blocking device for the freeze dryer includes a conical buffer hopper and a pipeline assembly

[0007] A buffer cavity is formed in the conical buffer hopper. The upper end of the conical buffer hopper is a receiving end.

The pipeline assembly is detachably connected to the automatic drainer of the freeze dryer. The lower end of the conical buffer hopper is a discharge end. The buffer cavity is also communicated with the discharge pipe of the freeze dryer through the discharge end, and the discharge end is detachably connected to the discharge pipe of the freeze dryer

[0008] In one embodiment, the buffer chamber includes a communicating transition sub-chamber and a funnel dropping chamber, and the transition sub-chamber is disposed adjacent to the receiving end.

[0010] The conical buffer hopper includes the receiving end, the discharging end and the hopper body, and the buffer chamber is formed in the hopper body. The receiving end, the discharging end and the hopper body are of an integrally formed structure.

[0011] In one embodiment, the pipeline assembly includes a multi-way connector and a plurality of connecting pipes. The multi-way connector includes a liquid outlet end and at least one liquid inlet end. The liquid outlet end is communicated with the receiving end, and each connecting pipe is communicated with the outlet of an automatic drainer of a freeze dryer.

[0012] In one embodiment, the liquid outlet end and the receiving end are in threaded connection.

[0013] In one embodiment, the steam and water blocking device for a freeze dryer further includes at least one discharging sub-pipe. The multi-way connector is formed with a plurality of discharging sub-ends, and each discharging sub-end is communicated with one discharging sub-pipe.

[0014] In one embodiment, the discharging end and the discharging pipe are in threaded connection.

[0015] In one embodiment, the steam and water blocking device for a freeze dryer further includes a locking fastener for detachably locking and fixing the connection between the discharging end and the discharging pipe.

[0016] In one embodiment, the locking fastener includes a first fastening semi-ring, a second fastening semi-ring and a locking member. The first fastening semi-ring and the second fastening semi-ring are rotatably arranged, and a sealing chamber is formed when the first fastening semi-ring and the second fastening semi-ring are fastened. The connection between the discharging end and the discharging pipe is located in the sealing chamber, and the locking member is used for detachably locking and fixing the first fastening semi-ring and the second fastening semi-ring.

[0017] A freeze dryer includes the steam and water blocking device for a freeze dryer according to any one of the above embodiments.

[0018] Compared with the prior art, the present disclosure has at least the following advantages:

[0019] 1) Since a buffer cavity is formed in the conical buffer hopper, the buffer cavity can be used to buffer and temporarily store condensed water.

The lower end of the conical buffer hopper is the discharge end, and the buffer cavity is also communicated with the discharge pipe of the freeze dryer through the discharge end, so that the steam-water mixture from the automatic drain of the freeze dryer can flow into the buffer cavity and be temporarily stored therein. Due to the action of gravity, the steam-water mixture in the buffer cavity can flow into the discharge pipe through the discharge end, so that the steam-water mixture discharged by the automatic drain can be subjected to the Venturi tube fluid vibration reduction jet action through the conical buffer hopper, thereby realizing effective buffering and pressure reduction of the steam-water mixture, that is, realizing the blocking and buffered discharge of the steam-water mixture, effectively avoiding the problem of backflow of the floor drain when the automatic drain discharges, thus ensuring the cleanliness of the site, and also effectively avoiding the situation that a large amount of steam-water mixture is discharged at one time and submerges some components, reducing the service life of the freeze dryer.

[0029] To facilitate the understanding of the present disclosure, the present disclosure will be described more comprehensively below with reference to the relevant drawings. Preferred embodiments of the present disclosure are shown in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure content of the present disclosure more thorough and comprehensive.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present disclosure belongs. The terms used in the description of the present disclosure herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0032] To better understand the technical solutions and beneficial effects of the present disclosure, the following further details the present disclosure with specific embodiments:

[0033] Please refer to Figure 1 , Figure 2 and Figure 6, A steam-water blocking device 10 for a freeze dryer according to an embodiment, the steam-water blocking device 10 for the freeze dryer includes a conical buffer hopper 100 and a pipeline assembly 200; a buffer cavity 111 is formed in the conical buffer hopper 100, the upper end of the conical buffer hopper 100 is a receiving end 120, and the buffer cavity 111 is sequentially communicated with the outlet of an automatic drainer (not shown in the figure) of the freeze dryer 1 through the receiving end 120 and the pipeline assembly 200; the pipeline assembly 200 is detachably connected to the automatic drainer of the freeze dryer 1; the lower end of the conical buffer hopper 100 is a discharge end 130, and the buffer cavity 111 is also communicated with the discharge pipe 21 of the freeze dryer 1 through the discharge end 130, and the discharge end 130 is detachably connected to the discharge pipe 21 of the freeze dryer 1.

[0034] It can be understood that since the buffer cavity 111 is formed in the conical buffer hopper 100, the buffer cavity 111 can be used to buffer and temporarily store condensed water; and since the upper end of the conical buffer hopper 100 is the receiving end 120, the buffer cavity 111 is sequentially communicated with the outlet of the automatic drainer of the freeze dryer 1 through the receiving end 120 and the pipeline assembly 200, the lower end of the conical buffer hopper 100 is the discharge end 130, and the buffer cavity 111 is also communicated with the discharge pipe 21 of the freeze dryer 1 through the discharge end 130, the steam-water of the automatic drainer of the freeze dryer 1 can flow to the buffer cavity 111 and be temporarily stored in the buffer cavity 111. Due to the action of gravity, the steam-water in the buffer cavity 111 can flow into the discharge pipe 21 through the discharge end 130, so that the steam-water discharged by the automatic drainer can perform a Venturi tube fluid vibration reduction jet action through the conical buffer hopper 100, thereby realizing effective buffering and pressure reduction of the steam-water, that is, realizing the blocking and buffered discharge of the steam-water, effectively avoiding the problem of backflow of the floor drain when the automatic drainer discharges, thus ensuring the cleanliness of the site, and also effectively avoiding the problem that the amount of steam-water discharged at one time is too large and submerging some components to reduce the service life of the freeze dryer.

[0035] It can also be understood that since the pipeline assembly 200 is detachably connected to the automatic drainer of the freeze dryer 1 and the discharge end 130 is detachably connected to the discharge pipe 21 of the freeze dryer 1, the detachable setting of the conical buffer hopper 100 and the freeze dryer 1 is realized. On the one hand, it is convenient for the user to install and clean; on the other hand, it is convenient for the user to replace the conical buffer hopper 100 with different capacities to better meet the needs of the single-time steam-water discharge of different specifications of the freeze dryer 1, thereby improving the adaptability of the steam-water blocking device 10.

[0036] Such as Figure 5 and Figure 6As shown, in one embodiment, the buffer chamber 111 includes a communicating transition sub-chamber 1111 and a funnel dropping chamber 1112. The transition sub-chamber 1111 is disposed adjacent to the receiving end 120, enabling the transition sub-chamber 1111 to provide better buffering for the freshly incoming soda water. Under the action of the funnel dropping chamber 1112, the soda water can achieve a better Venturi fluid vibration reduction jet effect and a faster flow-through, realizing better buffering and pressure reduction and discharging of the soda water, effectively avoiding the problem that too much soda water accumulates in the transition sub-chamber 1111 and affects the rapid discharge of the soda water in the buffer chamber 111.

[0037] In one embodiment, an arc transition portion is formed on the outer peripheral wall of the transition sub-chamber 1111 adjacent to the receiving end 120. The added arc transition portion facilitates the installation by the user and avoids the outer peripheral wall of the transition sub-chamber 1111 from being too sharp and scratching the user.

[0038] As Figure 5 and Figure 6 As shown, in one embodiment, the conical buffer hopper 100 includes the receiving end 120, the discharging end 130, and the hopper body 110. The buffer chamber 111 is formed inside the hopper body 110. The receiving end 120, the discharging end 130, and the hopper body 110 are of an integrally formed structure, making the receiving end 120, the discharging end 130, and the hopper body 110 of the conical buffer hopper 100 an integrally formed structure, thereby improving the service life of the conical buffer hopper 100.

[0039] As Figure 2 and Figure 3 As shown, in one embodiment, the pipeline assembly 200 includes a multi-way connector 210 and a plurality of connecting pipes 220. The multi-way connector 210 includes a liquid outlet end 211 and at least one liquid inlet end 212. The liquid outlet end 211 is communicatively connected to the receiving end 120. Each connecting pipe 220 is communicatively connected to the outlet of the automatic drainer of one freeze dryer 1, enabling the outlets of the automatic drainers of multiple freeze dryers 1 to be respectively communicatively connected to the corresponding connecting pipes 220. Thus, the soda water of the automatic drainers of multiple freeze dryers 1 can enter and flow into the multi-way connector 210 simultaneously, and flow through the liquid outlet end 211 of the multi-way connector 210 into the conical buffer hopper 100, thereby realizing the blocking and buffered discharge of the soda water of multiple freeze dryers 1.

[0040] As Figure 5 and Figure 6 As shown, in one embodiment, the liquid outlet end 211 and the receiving end 120 are in threaded connection to achieve the detachable setting of the multi-way connector 210 and the conical buffer hopper 100, facilitating the user to disassemble and assemble the conical buffer hopper 100.

[0041] As Figure 2 andFigure 3 As shown, in one embodiment, the steam and water blocking device 10 for the freeze dryer further includes at least one discharge sub-tube 230. The multi-way connector 210 is formed with a plurality of discharge sub-ends 213, and each discharge sub-end 213 is communicated with one discharge sub-tube 230.

[0042] It can be understood that when the multi-way connector 210 is connected to multiple freeze dryers 1, it is easy to cause a relatively large amount of steam and water to enter at one time, resulting in the single liquid outlet end 211 of the multi-way connector 210 being unable to better meet the requirements of quickly blocking and buffer discharging the steam and water of multiple freeze dryers 1 at the same time. Therefore, in one embodiment, by adding a plurality of discharge sub-ends 213 to the multi-way connector 210, the single discharge amount of the steam and water blocking device 10 is increased, so as to meet the requirements of multiple freeze dryers 1 operating simultaneously.

[0043] As Figure 5 and Figure 6 As shown, in one embodiment, the discharge end 130 and the discharge pipe 21 are in threaded connection to realize the detachable setting of the conical buffer hopper 100 and the discharge pipe 21, which is convenient for the user to disassemble and assemble the conical buffer hopper 100.

[0044] As Figure 5 and Figure 6 As shown, in one embodiment, the outer peripheral wall of the receiving end 120 is formed with a first external thread, and the inner part of the liquid outlet end 211 is formed with a first internal thread; the receiving end 120 is inserted into the liquid outlet end 211 and screwed with the first internal thread to realize the threaded connection between the liquid outlet end 211 and the receiving end 120.

[0045] As Figure 5 and Figure 6 As shown, in one embodiment, the outer peripheral wall of the discharge end 130 is formed with a second external thread, and the inner part of the discharge pipe 21 is formed with a second internal thread; the discharge end 130 is inserted into the discharge pipe 21 and screwed with the second internal thread to realize the threaded connection between the discharge end 130 and the discharge pipe 21.

[0046] As Figure 4 As shown, in one embodiment, the steam and water blocking device 10 for the freeze dryer further includes a locking and fastening member 300. The locking and fastening member 300 is used to detachably lock and fix the connection between the discharge end 130 and the discharge pipe 21, so that the added locking and fastening member 300 can improve the connection strength of the connection between the discharge end 130 of the conical buffer hopper 100 and the discharge pipe 21, effectively avoiding the problem that the conical buffer hopper 100 is prone to falling off during discharge.

[0047] Specifically, in one of the embodiments, the locking and fastening member 300 includes a first fastening half-ring 310, a second fastening half-ring 320 and a locking member 330. The first fastening half-ring 310 and the second fastening half-ring 320 are rotatably arranged to facilitate the user to open or fasten the first fastening half-ring 310. And when the first fastening half-ring 310 and the second fastening half-ring 320 are fastened, a sealing cavity is formed, so that the connection between the discharge end 130 and the discharge pipe 21 is located in the sealing cavity. The locking member 330 is used to detachably lock and fix the first fastening half-ring 310 and the second fastening half-ring 320, thereby realizing the detachable locking and fixing of the first fastening half-ring 310 and the second fastening half-ring 320, which is convenient for the user to disassemble and assemble.

[0048] In one of the embodiments, the locking member 330 is a screw. The first fastening half-ring 310 is formed with a first locking portion, and a threaded hole is formed in the first locking portion. The second fastening half-ring 320 is correspondingly formed with a second locking portion corresponding to the first locking portion, and a fixing hole is formed in the second locking portion. The screw sequentially passes through the fixing hole and the threaded hole and is screwed with the inner wall of the threaded hole, thereby realizing the detachable locking and fixing of the locking member 330 to the first fastening half-ring 310 and the second fastening half-ring 320. The user can manually loosen the screw to open the first fastening half-ring 310 and the second fastening half-ring 320, and then lock the screw back and tighten it to realize the locking of the first fastening half-ring 310 and the second fastening half-ring 320.

[0049] As Figure 1 and Figure 2 shown, the present disclosure also provides a freeze dryer 1, including the steam and water blocking device 10 for the freeze dryer described in any of the above embodiments. In this embodiment, the freeze dryer 1 includes a freeze dryer body 20 and a steam and water blocking device 10. The freeze dryer body 20 includes a refrigeration component and an automatic drainer. The automatic drainer is communicated with the refrigeration component, and the outlet of the automatic drainer is communicated with the conical buffer hopper 100 through a pipeline assembly 200 to realize the blocking and buffer discharge of the steam and water in the freeze dryer 1.

[0050] Compared with the prior art, the present disclosure has at least the following advantages:

[0051] 1) Since a buffer cavity 111 is formed in the conical buffer hopper 100, the buffer cavity 111 can be used to buffer and temporarily store the steam water. Also, since the upper end of the conical buffer hopper 100 is a receiving end 120, the buffer cavity 111 is sequentially communicated with the outlet of the automatic drain of the freeze dryer 1 through the receiving end 120 and the pipeline assembly 200. The lower end of the conical buffer hopper 100 is a discharge end 130, and the buffer cavity 111 is also communicated with the discharge pipe 21 of the freeze dryer 1 through the discharge end 130, so that the steam water from the automatic drain of the freeze dryer 1 can flow into the buffer cavity 111 and be temporarily stored in the buffer cavity 111. Due to the action of gravity, the steam water in the buffer cavity 111 can flow into the discharge pipe 21 through the discharge end 130, so that the steam water discharged by the automatic drain can carry out the venturi tube fluid vibration reduction jet action through the conical buffer hopper 100, thereby realizing effective buffering and pressure reduction of the steam water, that is, realizing the blocking and buffered discharge of the steam water, effectively avoiding the problem of backflow of the floor drain when the automatic drain discharges, thus ensuring the cleanliness of the site, and effectively avoiding the phenomenon of water flooding on the ground when the amount of steam water discharged at one time is relatively large, thereby improving the service life of the freeze dryer 1.

[0052] 2) Since the pipeline assembly 200 is detachably connected to the automatic drain of the freeze dryer 1, and the discharge end 130 is detachably connected to the discharge pipe 21 of the freeze dryer 1, the detachable setting of the conical buffer hopper 100 and the freeze dryer 1 is realized. On the one hand, it is convenient for users to install and clean; on the other hand, it is convenient for users to replace the conical buffer hopper 100 with different capacities to better meet the needs of the single - time steam water discharge of different specifications of the freeze dryer 1, thereby improving the adaptability of the steam water blocking device 10.

[0053] The above - mentioned embodiments only represent several implementation manners of the present disclosure. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the disclosed patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several deformations and improvements can be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
