Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of laboratory equipment, especially relates to a thick liquid splash-proof cover. BACKGROUND

[0002] It is a routine operation to heat or sterilize thick liquid in the laboratory, and the splash often occurs due to the local overheating, slow heat convection and other reasons in the liquid heating process.

[0003] The common solution is to stir when heating, add gasification center such as zeolite, glass bead and the like, reduce the liquid depth, increase the liquid surface area, control the heating speed and the like.

[0004] However, these methods increase the use scene limitation. For example, stirring cannot be used in the sterilization operation. The control of the heating speed needs more complex equipment. The addition of the gasification center increases the solid-liquid separation operation and still causes the splash. The method of reducing the liquid depth and increasing the liquid surface area needs to increase the container quantity or operation times, and the material loss on the container wall increases.

[0007] The top of the splash-proof cover shell is in a concave shape, which is beneficial to the material adhered to the inner wall of the cover to gather to the center when splashing, the convex design at the edge of the conical bottom is beneficial to the material gathered to the center to gather into drops at the place and then fall back into the material below, and the convex design avoids the gathered material from contacting the paddle rod, so that the loss of the material during recycling is reduced as much as possible.

[0008] Preferably, the paddle comprises two parts of a paddle rod and a paddle blade, and the upper part of the paddle rod is rotationally connected with the internally threaded pipe of the splash-proof cover shell through the internal thread.

[0009] Preferably, the paddle blade is made of stainless steel and is in a cross shape.

[0010] Preferably, the splash-proof cover shell is provided with an internal thread below, and the sealing silica gel ring is arranged on the internal thread.

[0011] Preferably, the filter head is a one-way filter valve, which can exhaust air but prevents external air from entering.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] 1. The utility model has simple structure, does not need to increase additional equipment such as stirring and temperature control, and is widely applied, that is, can be used for normal pressure heating and high pressure steam sterilization. Especially in the high pressure steam sterilization scene, it can prevent material spatter loss and seal damage during sterilization to cause sterilization failure.

[0014] 2. The concave design at the top of the shell can recycle spattered material or evaporated solvent, and reduce material loss and material concentration change caused by solvent evaporation. BRIEF DESCRIPTION OF DRAWINGS

[0018] The technical scheme of the utility model patent will be further specifically explained below by combining with the drawings.

[0019] Embodiment:

[0020] An anti-spatter cover for viscous liquid, comprising: an anti-spatter cover shell 1, a filter head 2, a silica gel gasket 3, a sealing silica gel ring 4 and a paddle 5, the silica gel gasket 3 is arranged at the top end of the anti-spatter cover shell 1, and the silica gel gasket 3 is used for buffering and preventing glass containers from being damaged, and the top of the anti-spatter cover shell 1 is concave, which is beneficial to the material splashed on the inner wall of the cover to gather to the center.

[0021] An internally threaded pipe 6 is arranged at the lowest part of the center of the anti-spatter cover shell 1, that is, the lowest part of the concave, the internally threaded pipe 6 and the anti-spatter cover shell 1 have a conical strengthening design, the anti-spatter cover shell 1 has a protrusion 7 at the edge of the conical bottom, the internally threaded pipe 6 is used for connecting with the paddle 5, the design of the protrusion 7 is beneficial to the material gathered to the center to gather into drops at this place and then fall back into the material below, meanwhile, the protrusion design avoids the gathered material from contacting the paddle rod, so as to minimize the loss of the material during recycling and the change of the concentration of the material caused by solvent evaporation.
