The utility model has the advantages of simple structure, and is simple and convenient to manufacture and install. Come whole cladding peristaltic pump hose outer wall through the protection pipeline, form effectual isolated protection, fine solution the problem of sample loss after the explosion of tubes to and the problem that liquid splashes after the explosion of tubes, stop the harmful substance in the sample to cause the injury to the human body.
Description
Technical Field
The utility model belongs to the technical field of the protein purification technique and specifically relates to a peristaltic pump hose protector is used in filtration of protein sample is related to.
Background
In the process of protein purification solid-liquid separation, particularly in the process of large-scale production, liquid to be separated is conveyed into a plate frame type filter press for filtration through a peristaltic pump; but as the solid residue is accumulated in the plate frame, the filtering pressure is gradually increased, and the hose of the peristaltic pump is easy to burst; once a peristaltic pump hose is exploded, sample loss can be caused, the sample is precious, and waste caused by sample loss can greatly improve the protein purification cost; meanwhile, liquid splashing can occur during tube explosion, so that harmful substances in the sample can cause harm to human bodies. Therefore, in the existing protein purification operation, a device capable of effectively preventing the liquid from running off or splashing after the peristaltic pump hose is burst is urgently needed.
Disclosure of Invention
The utility model aims to provide a protein sample filters uses peristaltic pump hose protector simple structure, simple installation.
In order to achieve the above purpose, the utility model can adopt the following technical proposal:
the peristaltic pump hose protection device for filtering protein samples comprises a protection pipeline which is adaptive to and attached to the outer wall of a peristaltic pump hose, wherein the protection pipeline is formed by buckling a left pipe piece and a right pipe piece with semicircular sections; the buckling edges of the left duct piece and the right duct piece are turned outwards to form two pairs of connecting edges which are mutually attached, and a plurality of groups of duct piece connecting holes are arranged on each pair of connecting edges at intervals along the length direction; the both ends of left and right section of jurisdiction all set firmly rather than outer wall looks vertically connecting plate, are located two of same end department connecting plate adaptation lock forms flange last edge the circumference equipartition of peristaltic pump hose has a plurality of pipeline connecting holes.
Sealing members are arranged on the binding surfaces of each pair of the connecting edges; specifically, the sealing member can be along length direction offer in wherein one side connect the draw-in groove on the limit to and set up on the opposite side connect the edge with the card strip of draw-in groove adaptation joint.
Of course, the sealing member may also be a rubber sealing gasket fixedly disposed on the joint surface of the joint edge, and a connection through hole corresponding to the duct piece connection hole is formed in the rubber sealing gasket along the length direction.
The utility model has the advantages of simple structure, and is simple and convenient to manufacture and install. The outer wall of the peristaltic pump hose is integrally coated by the protective pipeline formed by buckling the left tube piece and the right tube piece, so that the support and protection capacity of the peristaltic pump hose is enhanced while the peristaltic pump is ensured to normally work, and the phenomenon of tube burst is avoided to the greatest extent; in addition, the protection pipeline also forms effective isolation protection, well solves the problem of sample loss after tube explosion and the problem of liquid splashing after tube explosion, and avoids the harm of harmful substances in the sample to human bodies.

Detailed Description
As shown in figure 1, protein sample filter uses peristaltic pump hose protector, include the protective tube who laminates with peristaltic pump hose outer wall adaptation, this protective tube is formed by section semicircular structure's left section of jurisdiction 1 and right section of jurisdiction 2 lock, left section of jurisdiction 1 and right section of jurisdiction 2 are made by stainless steel material, the reinforcing is to the support of peristaltic pump hose and protective capacities.
The inseparable lock of being convenient for left section of jurisdiction 1 and right section of jurisdiction 2 is connected, the upper and lower two sets of lock border departments of left side section of jurisdiction 1 and right section of jurisdiction 2 all to turning up, form two pairs of connection limits 3 of laminating each other, all be equipped with multiunit section of jurisdiction connecting hole 4 along length direction spaced apart on every connecting limit 3, just can easily realize the inseparable lock of left section of jurisdiction 1 and right section of jurisdiction 2 through the connecting bolt who wears to locate in section of jurisdiction connecting hole 4, and then install on the outer wall of peristaltic pump hose.
Because the length of peristaltic pump hose is not necessary, consequently in order to splice out the protection pipeline of arbitrary length, all set firmly at the both ends of a left side section of jurisdiction 1 and a right side section of jurisdiction 2 rather than outer wall looks vertically connecting plate 5, the 5 adaptation locks of two connecting plates that are located same end department form flange, have a plurality of pipeline connecting holes 6 along the circumference equipartition of peristaltic pump hose on this flange, connecting bolt passes pipeline connecting hole 6 just can easily be with two sections protection pipeline zonulae occludens.
In order to enhance the sealing performance at the joint surfaces of the two pairs of connecting edges 3, a sealing member is arranged on the joint surface of each pair of connecting edges 3. As shown in fig. 2 and 3, the sealing member may be a slot 7 formed on one of the connecting edges 3 along the length direction, and a strip 8 disposed on the other connecting edge 3 and adapted to be engaged with the slot 7; the clamping groove 7 is matched and clamped with the clamping strip 8, so that a labyrinth type sealing structure is formed, and the sealing property of the binding surface of the connecting edge 3 is enhanced; of course, the clamping grooves 7 and the clamping strips 8 can be arranged in a plurality of ways as long as the opening of the segment connecting holes 4 is not affected.
In addition, as shown in fig. 4 and 5, the sealing member may also be a rubber sealing gasket 9 fixedly arranged on the binding surface of the connecting edge 3, and a connecting through hole corresponding to the segment connecting hole 4 in a matched manner is formed in the rubber sealing gasket 9 along the length direction, so as to ensure that the connecting bolt can pass through the segment connecting hole 4; come the gap of sealed connection 3 binding face departments on limit through rubber seal pad 9, avoid the sample after the booster to flow from the gap, strengthen the leakproofness of this device.
