Description
Technical field
The present invention relates to a kind of hopper cover.
Background technology
Mixer utilizes mechanical force and gravity etc., by the mechanical equipment that two or more material Homogeneous phase mixing gets up.
In the process of mixing, material contact surface area can also be increased, to promote chemical reaction; Physical change can also be accelerated.Conventional mixer is divided into gas and the large class of low-viscosity (mobile) liquid mixer, medium-high viscosity liquid and paste mixer, powdery and particulate solid material mixing machinery four.Therefore various industry is widely used in, particularly the permanent industry such as medical treatment, food, fine chemistry industry.
Mixer is mainly used in the mixing of particulate matter in the industries such as pharmacy, food, fine chemistry industry or powder; the hopper cover of existing mixer hopper is connected with cylindrical shell by hasp; leak tightness is poor; in use often there is the phenomenon of spattering leakage; because leak tightness is poor; the trickle materials such as outside dust are also easy to enter hopper inside, thus the material in feed hopper pollutes, and bring very large inconvenience to production.
Three safeguard that oscillating mixer principle of work and traditional swinging mixer are not quite similar, it is spatially done unique translation, rotation, rock and roll motion at cubical three-dimensional, makes material in mixing drum, be in the state of kinematic motion of complexity such as " rotational flow-translations-put upside down falling bodies ", i.e. so-called TURBULA state; Produce one ALT pulse, continuously promote material, the turbulence then vicissitudinous energy gradient that motion produces, thus make each particle in mixed material have can not state of kinematic motion, each particle, in the position in diffusion constantly residing for change oneself of moving frequently, creates satisfied mixed effect.
Three-dimensional oscillating mixer is made up of parts such as support, drive system, three-dimensional motion mechanism, mixing drum and electrical apparatus control systems, and the mixing drum directly contacted with material adopts the manufacture of high-quality stainless steel material, and cylinder inboard wall is through precise polished.
Series three-dimensional oscillating is a kind of extensively in the novel material mixer of the industries such as pharmacy, chemical industry, food, light industry and R&D institution.This function is the powdery of Homogeneous phase mixing good flowing properties or granular material very, makes the material of mixing reach optimum efficiency.Therefore just high especially to the requirement of mixer hopper cover.
Patent No. name is called the patent of the device for fastening of batch charger hopper cover, the device for fastening of this batch charger hopper cover comprises button dish, buckle, iron wire frame, hopper cover and hopper ladle body, wherein iron wire frame is assemblied in the inwall of hopper cover, after button dish and buckle are assembled, buckle is assemblied in hopper cover, button dish is assemblied on hopper ladle body, tightens up with the fastening realizing hopper cover and hopper ladle body.Although this hopper cover device for fastening structure is simple, easy to operate, but air-tightness is poor, leak tightness is not enough, trickleer particle, powder or gas are easy to enter into barrel, thus cause the material in hopper to pollute, therefore the securing device of this hopper cover is not suitable for the industry such as pharmacy, food, fine chemistry industry higher to air-tightness requirement.
Summary of the invention
[0006] the object of the invention is to overcome above deficiency, providing that a kind of structure is simple, good airproof performance, not easily spatter the hopper cover of leakage.
Object of the present invention is achieved through the following technical solutions: a kind of hopper cover, comprise lid, evenly hasp is provided with in the periphery of lid, connector and multiple pinch device, described pinch device comprises the compression limit be connected with lid, packing seal is provided with in the lower surface contacted with cylindrical shell on described compression limit, for to the sealing compressed between limit and cylindrical shell, the first compact heap is provided with in the upper end on described compression limit, the second compact heap is connected with in the outside compressing limit, handle is provided with in the second compact heap upper end, pull bar is provided with in described handle, the bottom of the second compact heap is passed in the lower end of described pull bar, pivot pin is provided with in the bottom of described pull bar, described packing seal is annular arrangement, described packing seal is made up of the soft silica gel on upper strata and the rubber of lower floor, in use, inner air and outer air can completely cut off by soft layer of silica gel, sealing effectiveness is better.
The present invention compared with prior art has the following advantages:
Structure of the present invention is simple, good airproof performance, not easily side leakage, ensures hopper smooth running.
accompanying drawing illustrates:
Fig. 1 is birds-eye view of the present invention;
Fig. 2 is front view of the present invention;
Number in the figure: 1-lid, 2-hasp, 3-pinch device, 4-connector, 5-compress limit, 6-packing seal, 7-first compact heap, 8-second compact heap, 9-handle, 10-pull bar, 11-pivot pin.
detailed description of the invention:
in order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
As Fig. 1 and Fig. 2 shows a kind of embodiment of hopper cover: comprise lid 1, hasp 2 is evenly provided with in the periphery of described lid 1, connector 4 and multiple pinch device 3, described pinch device 3 comprises the compression limit 5 be connected with lid 1, packing seal 6 is provided with in the lower surface contacted with cylindrical shell on described compression limit 5, the first compact heap 7 is provided with in the upper end on described compression limit 5, the second compact heap 8 is connected with in the outside on described compression limit 5, handle 9 is provided with in described second compact heap 8 upper end, pull bar 10 is provided with in described handle 9, the bottom of the second compact heap 8 is passed in the lower end of described pull bar 10, pivot pin 11 is provided with in the bottom of described pull bar 10, described packing seal 6 is annular arrangement, for to the sealing compressed between limit and cylindrical shell, described packing seal 6 is made up of the soft silica gel on upper strata and the rubber of lower floor, in use, inner air and outer air can completely cut off by soft layer of silica gel, sealing effectiveness is better.
The present invention is evenly placed with multiple pinch device around hopper cover; by the pull bar in handle; and the compactness of pinch device and hopper cover and hopper is increased by packing seal; make the better tightness of hopper; not easily spatter leakage; material in protection hopper does not receive pollution, also ensure that the smooth running of hopper simultaneously.
The another statement of applicant, the present invention illustrates implementation method of the present invention and apparatus structure by above-described embodiment, but the present invention is not limited to above-mentioned embodiment, does not namely mean that the present invention must rely on said method and structure could be implemented.Person of ordinary skill in the field should understand, any improvement in the present invention, replaces and the interpolation of step, concrete way choice etc., all drop within protection scope of the present invention and scope of disclosure implementation method equivalence selected by the present invention.The present invention is not limited to above-mentioned embodiment, and all employings and analog structure of the present invention and method thereof realize all modes of the object of the invention, all within protection scope of the present invention.
