Description

Technical Field

[0001] This utility model relates to the field of barrel leak detection technology, and in particular to a leak detection device for dialysis dry powder barrels. Background Technology

[0002] Hemodialysis dry powder is suitable for sodium bicarbonate dialysis treatment of patients with acute or chronic renal failure or acute poisoning by dialyzable toxins. Hemodialysis dry powder must be stored in a dry powder container. The container lid usually has an inlet, and the bottom of the container has an outlet, generally using either a "top inlet, bottom outlet" or "bottom inlet, top outlet" method.

[0003] The airtightness of the hemodialysis dry powder container is crucial to its quality. After production, the airtightness of the dry powder container after welding needs to be tested. Existing devices for testing the airtightness of dry powder containers are inefficient and have room for improvement. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a leak detection device for dialysis dry powder containers.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a leak detection device for dialysis dry powder tanks, comprising:

[0006] The inspection turntable has a transmission rod at its center.

[0007] A mounting frame is mounted on a transmission rotating rod and has multiple mounting rings for supporting dry powder barrels.

[0008] An air supply mechanism is provided at the top of the transmission rod. The air supply mechanism includes multiple sets of swing arm brackets. The position of the swing arm brackets corresponds to the mounting ring, and the swing arm brackets are provided with air injection heads that contact the dry powder barrel.

[0009] The contact platform is fixedly installed above the gas supply mechanism. The contact platform is equipped with a stop block, which is used to stop the rotation of the swing arm bracket and to connect the gas injection end with the dry powder tank.

[0010] Furthermore, the detection turntable is equipped with a drive unit and an air supply unit.

[0011] The drive unit is used to drive the transmission rod to rotate at a constant speed;

[0012] The air supply unit is used to supply pressure to the inside of the dry powder tank connected to it through the air injection end, and to monitor the air pressure changes.

[0013] Furthermore, the air supply mechanism includes a rotating disk disposed at the top of the transmission rod, and the rotating disk is provided with multiple sets of rotating grooves;

[0014] The swing arm bracket is hinged in the rotating groove;

[0015] A reset torsion spring is provided in the rotating groove to drive the swing arm bracket to reset.

[0016] Furthermore, the swing arm bracket is rotatably connected to the gas injection end, so that the gas injection end remains in a vertical position during the rotation of the swing arm bracket.

[0017] Furthermore, the contact platform is equipped with multiple sets of contact blocks.

[0018] Furthermore, the side of the detection turntable is provided with a fixed bracket for supporting the contact platform.

[0019] The beneficial effects of this utility model are reflected in:

[0020] This utility model features a contact platform positioned above the gas supply mechanism. When the gas supply mechanism rotates and drives the swing arm bracket to rotate to the side with the contact block, the corresponding swing arm bracket and the gas injection end on the gas supply mechanism are squeezed down by the contact block. During the contact process between the gas injection end and the dry powder container, gas at a certain pressure is injected into it, and the container rotates synchronously for a certain period of time while monitoring the pressure change. If no change occurs, it indicates that the dry powder container is intact. If the pressure slowly decreases after the gas is injected, it indicates that there is a leak in the dry powder container.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0031] Please see Figure 1-2 This utility model discloses a leak detection device for dialysis dry powder tanks, characterized in that it includes:

[0032] The testing turntable 1 has a transmission rotating rod 2 at its center. Preferably, the testing turntable 1 is a disc-shaped support platform with a mounting cavity inside and a control unit on it. It should be noted that the testing turntable 1 has a drive unit and an air supply unit located inside the mounting cavity.

[0033] The mounting frame 3 is mounted on the transmission rod 2 and has multiple mounting rings for supporting the dry powder bucket. The multiple mounting frames 3 are arranged in a star shape and can be used to drive the dry powder bucket to rotate in a ring for subsequent testing processes.

[0034] Gas supply mechanism 4 is located at the top of transmission rod 2. Gas supply mechanism 4 includes multiple sets of swing arm brackets 42. The position of the swing arm brackets 42 corresponds to the mounting ring, and the swing arm brackets 42 are provided with gas injection end 6 that contacts the dry powder barrel.

[0035] The contact platform 5 is fixedly installed above the gas supply mechanism 4. The contact platform 5 is provided with a stop block 51, which is used to stop the swing arm bracket 42 from rotating and to connect the gas injection end 6 with the dry powder tank.

[0036] The drive unit is used to drive the transmission rod 2 to rotate at a constant speed. The output end of the drive unit is fixedly connected to the transmission rod 2 to drive the transmission rod 2 to rotate slowly so that manual material handling and feeding can be carried out, and the auxiliary equipment can complete the leak detection process.

[0037] The gas supply unit is used to supply pressure to the dry powder canister connected to it through the gas injection end 6 and monitor the gas pressure change. It should be noted that the control unit proposed in the above structure includes a pressure detector, which can be used to monitor the change of internal pressure of the gas injection end 6 during the contact process with the dry powder canister. If there is no change, it means that the dry powder canister is intact. If the pressure slowly decreases after gas injection, it means that there is a leak in the dry powder canister.

[0038] In this application, the gas supply mechanism 4 includes a rotating disk disposed at the top of the transmission rod 2, and the rotating disk is provided with multiple sets of rotating grooves 41;

[0039] The swing arm bracket 42 is hinged in the rotating groove 41;

[0040] A reset torsion spring is provided in the rotating groove 41 to drive the swing arm bracket 42 to reset, so that after the test is completed, the swing arm bracket 42 drives the air injection end 6 to disengage from the dry powder barrel, so as to facilitate subsequent material handling and subsequent feeding.

[0041] It is easy to imagine that the swing arm bracket 42 is rotatably connected to the air injection end 6 so that the air injection end 6 can maintain a vertical posture during the rotation of the swing arm bracket 42. In the above structure, the air injection end 6 can maintain a vertical state due to its own weight, so as to connect with the air inlet end of the dry powder tank.

[0042] Preferably, the contact platform 5 is provided with multiple sets of abutment blocks 51. By setting multiple sets of abutment blocks 51, the swing arm bracket 42 can swing down multiple times and the air injection end 6 can be connected with the dry powder barrel multiple times, thereby facilitating the re-inspection and other processes.

[0043] Finally, as shown in the figure, in this application, the side of the detection turntable 1 is provided with a fixed bracket to support the contact platform 5. The fixed bracket is used to fix the contact platform 5 above the gas supply mechanism 4, so that the two rotate relative to each other. When the gas supply mechanism 4 rotates to the side with the block 51, the corresponding swing arm bracket 42 and the gas injection end 6 on the gas supply mechanism 4 are squeezed by the block 51 and fall down, contacting the dry powder barrel for leakage detection.

[0044] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0045] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0046] Additionally, "multiple" refers to two or more.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
