Description

Technical Field

[0001] The utility model relates to the technical field of biomedical equipment manufacturing, in particular to an integrated waste discharge fixture. Background Art

[0002] At present, the lower waste outlet of the widely used clamp is open, such as Figure 4 As shown, it is usually necessary to install a valve below the lower waste outlet to control the opening and closing of the lower waste outlet. The connection method usually adopts installing a flat joint at the lower waste outlet and welding a valve at the other end of the flat joint. Such a connection will cause the connection distance between the fixture and the valve to be too long and there will be a lot of solution residue. This part of the solution cannot be recycled and causes waste. For example, when the ultrafiltration process is a clarification process, the permeate needs to be collected, and the value of this wasted solution is often very high; secondly, when the solution in the channel is switched, the residual liquid will cause cross-contamination to the product or the next process, such as causing product denaturation and inactivation or causing the next process to fail to meet the relevant parameter requirements. Utility Model Content

[0003] The purpose of the utility model is to solve the above-mentioned problem and provide an integrated waste discharge fixture. The waste discharge fixture and the valve adopt an integrated structure to reduce the connection distance between the two, thereby reducing the dead corners of solution residue, thereby avoiding the waste of resources caused by the solution remaining in the dead corners and reducing the cross contamination caused by the residual liquid to the next process.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an integrated waste discharge clamp, comprising a clamp body having a solution inlet for solution to enter and a lower waste outlet for discharging waste liquid, characterized in that: the clamp body has a second channel for waste liquid to circulate, the second channel has a permeation port for waste liquid to enter and a lower waste outlet opposite to the permeation port for waste liquid to discharge, the solution enters the clamp body from the solution inlet, passes through an external membrane package, and then is discharged from the lower waste outlet after passing through the permeation port, the lower waste outlet is provided with a valve body for controlling the on and off of the waste liquid, and the valve body is integrally connected to the clamp body.

[0005] According to the utility model, further, the valve body and the lower waste discharge port are detachably connected in one piece.

[0006] According to the utility model, further, a first threaded hole corresponding to the flange position of the valve body is opened on the second surface of the clamp body, and a screw passes through the flange of the valve body and is connected to the first threaded hole to achieve a fixed connection between the valve body and the clamp body.

[0007] According to the utility model, further, the valve body adopts a diaphragm valve or a plunger valve.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1-5As shown, an integrated waste discharge fixture in an embodiment of the utility model is a fixture body 100 used in an ultrafiltration device, which is installed on one side of a membrane package 300. The fixture body 100 is a cube, having a first surface 110 and a second surface 120 opposite to the first surface 110. The fixture body 100 includes three parallel channels, and the inner walls of the channels are provided with solution channels 170 connected to the membrane package 300, so as to realize the flow and circulation of the solution between the channels and the membrane package 300. The three channels all penetrate the first surface 110 and the second surface 120, and the channels are respectively the first channel 140, the second channel 150 and the third channel 160. The first channel 140 has a reflux port 141 to facilitate the reflux of the solution; the second channel 150 has a through port 151 located on the first surface 110 and a lower waste port 152 opposite to the through port 151, and the lower waste port 152 is integrally fixedly connected with a valve body 200, so that the flow of the liquid in the lower waste port 152 is controlled by the valve body 200; the third channel 160 has a solution inlet 161 located on the second surface 120. The solution enters the third channel 160 from the solution inlet 161 through the pipeline, flows to the membrane package 300 through the solution channel 170 on the inner wall of the third channel 160, and then enters the reflux port 141 of the first channel 140 through the membrane package 300, and enters the second channel 150 through the through port 151 to flow to the lower waste port 152. The valve body 200 and the lower waste outlet 152 are detachably connected as one body. If the valve body 200 or the fixture body 100 is damaged, it is also convenient to replace them separately. Preferably, a first threaded hole 130 is opened at the bottom of the fixture body 100, and multiple first threaded holes 130 are distributed on the periphery of the lower waste outlet 152. According to the model of the valve body 200, a suitable first threaded hole 130 is selected for matching connection. The through hole of the flange of the valve body 200 itself coincides with the first threaded hole 130, and the screw passes through the flange threaded hole of the valve body 200 and the first threaded hole 130 to achieve a fixed connection between the two. Preferably, the valve body 200 can adopt a diaphragm valve or a plunger valve. Among them, the membrane package 300 is an existing equipment and will not be repeated here.

[0016] Working principle: When the ultrafiltration device filters the solution, the sample solution enters the third channel 160 of the fixture body 100 through the solution inlet 161, and flows to the membrane package 300 through the solution channel 170 set on its inner wall. After the solution circulates in the membrane package 300, the reflux liquid flows into the first channel 140 through the reflux port 141, and the permeate enters the second channel 150 from the permeate port 151, and then flows out from the lower waste port 152. The opening and closing of the valve body 200 determines the on-off of the second channel 150, thereby realizing the discharge of waste liquid. The inner wall of the entire flow channel is smooth and there is no connection point, which reduces the generation of dead corners and improves the waste liquid discharge rate.

[0017] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
