Description

Vacuum freeze dryer plate layer plug at end part

Technical field

The utility model belongs to vacuum freeze drier plate layer accessory technical field, in particular relates to vacuum refrigeration Drying machine plate layer plug at end part.

Background technique

In drug or food processing field, in order to mostly use vacuum freeze dryer greatly for drug or food drying, it is By refrigeration system, vacuum system, heat-conducting oil heating system and the combined integrated body structure of dehumidification system.The plate layer includes upper steel Plate, lower steel plate and keel are located in the middle, have plug at end part at keel both ends.At present plug at end part include insertion upper steel plate and Insertion end and tail end between lower steel plate, insertion end and tail end are step-like integral structure, the thickness of insertion end and tail end The difference of thickness is equal with the sum of the thickness of upper steel plate and lower steel plate.The plug at end part of above structure has the following defects, first, weldering When connecing, upper steel plate and insertion end are welded together, poor sealing effect, service life is short；Fourth, since insertion end and tail end are Step-like integral structure, in order to guarantee upper steel plate, lower steel plate and plug at end part junction air-tightness, the upper steel plate needed It is larger with the thickness of lower steel plate, cannot using welder for seam welding keel and upper steel plate and lower steel plate, cause keel and upper steel plate, under Steel plate bonding strength is low, and service life is short, thermal conduction effect is poor, causes the non-uniform temperature of upper steel plate and lower steel plate.

Utility model content

The technical issues of the utility model solves just is to provide the vacuum refrigeration that a kind of sealing effect is good, thermal conduction effect is good Drying machine plate layer plug at end part.

In order to solve the above technical problems, the utility model proposes vacuum freeze dryer plate layer used with plug at end part Technical solution are as follows: including interior closure and outer closure, the section of the interior closure is the rectangle that side has trapeze cut, described outer The section of closure includes plug and the support plate positioned at plug rear end, and the shape of the plug is matched with the trapeze cut, institute Plug is stated to be inserted into the trapeze cut.

Its additional technical feature are as follows:

The trapeze cut isosceles trapezoid；

The acute angle base angle of the trapeze cut is 45 degree.

Vacuum freeze dryer plate layer plug at end part provided by the utility model compared with the existing technology relatively has following Advantage: first, due to including interior closure and outer closure, the section of the interior closure is the rectangle that side has trapeze cut, institute The section for stating outer closure includes plug and the support plate positioned at plug rear end, the shape of the plug and the trapeze cut Match, the plug is inserted into the trapeze cut, and plug at end part includes interior closure and two independent devices of outer closure, is being welded When, it is first that interior side of the closure with trapeze cut is outside, it is inserted between the upper steel plate and lower steel plate at keel both ends, makes interior envelope Stifled outer is aligned with the outer of upper steel plate and lower steel plate, and by it is interior block close to outside both sides up and down respectively with upper steel plate, Lower steel plate welding；Interior block is welded with upper steel plate, lower steel plate respectively close to the both sides up and down in outside using argon arc welding；By covering It in the notch blocked in stifled plug insertion, blocks welded with upper steel plate, lower steel plate joint outside, and by the notch of joint It fills and leads up, interior closure is first passed through into argon arc welding welding with upper steel plate and lower steel plate, sealing effect is good, and the plate layer of the structure is upper The thickness of steel plate and lower steel plate can be welded together upper steel plate, lower steel plate and keel by seam welder less than 3 millimeters, weldering It connects that high-efficient, welding quality is good, not only increases bonding strength, but also heat conduction efficiency can be improved, it is energy saving；Its Two, due to the trapeze cut isosceles trapezoid, the acute angle base angle of the trapeze cut is 45 degree, not only easy to process, Er Qieqiang Degree is high.

Fig. 4 is the structural schematic diagram of the vacuum freeze drier plate layer prepared with the plug at end part.

Specific embodiment

The vacuum freeze dryer plate layer end that the utility model is proposed with reference to the accompanying drawings and detailed description The structure and be described further using principle that portion blocks.

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the structure of the utility model vacuum freeze dryer plate layer plug at end part is shown It is intended to, the utility model vacuum freeze dryer plate layer plug at end part includes interior closure 1 and outer closure 2, the section of interior closure 1 The rectangle of trapeze cut 11 is had for side, the section of outer closure 2 includes plug 21 and the support plate 22 positioned at plug rear end, is inserted First 21 shape is matched with trapeze cut 11, and plug 21 is inserted into trapeze cut 11, and plug at end part includes interior closure 1 and outer closure 2 two independent devices.As shown in figure 4, in welding, first that interior 1 side with trapeze cut 11 that blocks is outside, insertion Between the upper steel plate 4 and lower steel plate 5 at 3 both ends of keel, it is aligned the outer of interior closure 1 with the outer of upper steel plate 4 and lower steel plate 5, And interior closure 1 is welded with upper steel plate 4, lower steel plate 5 respectively close to the both sides up and down in outside；Interior closure 1 is leaned on using argon arc welding It is welded respectively with upper steel plate 4, lower steel plate 5 on the both sides up and down in nearly outside；The plug 21 of outer closure 2 is inserted into the notch of interior closure 1 In 11, block 2 outside and welded with upper steel plate 4,5 joint of lower steel plate, and the notch of joint is filled and led up, first by interior closure with it is upper Steel plate and lower steel plate are by argon arc welding welding, and sealing effect is good, and the thickness of the upper steel plate of the plate layer of the structure and lower steel plate Upper steel plate, lower steel plate and keel can be welded together by seam welder less than 3 millimeters, welding efficiency height, welding quality It is good, bonding strength is not only increased, but also heat conduction efficiency can be improved, it is energy saving.

11 isosceles trapezoid of trapeze cut, the acute angle base angle of trapeze cut 11 is 45 degree, not only easy to process, and intensity It is high.

The protection scope of the utility model is not limited solely to above-described embodiment, as long as structure and the utility model vacuum are cold Lyophilizer plate layer is same or similar with plug at end part structure, just falls in the range of the utility model protection.
