Example 1

Referring to fig. 1, the choke type drying box for drying chemical materials in this embodiment includes a box body 1 and a drying cart 2, and the air inlet and the moisture exhaust port of the box body 1 in this embodiment may be designed conventionally, so long as they can intake air transversely, without specific limitations. An air inlet duct 101 is provided on the left side of the cabinet 1, the air inlet duct 101 is disposed in a vertical direction, and an air inlet 102 is connected to the air inlet duct 101. The air inlet 102 communicates the air inlet duct with the inner cavity of the box body, and the air inlets 102 are transversely arranged and are spaced from each other in the vertical direction to allow the drying air to transversely enter to form a plurality of air inlets.

An exhaust duct 103 is arranged on the right side of the box body 1, and transverse exhaust ports 104 are arranged on the exhaust duct 103 at intervals. The air outlet 104 and the air inlet 102 are identical in structure, hot air after drying materials enters the air exhaust duct 103 through the air outlet 104, the materials are recycled after being dehumidified, and the materials on the drying trolley 2 are dried through circulating hot air.

This embodiment has also improved drying trolley 2, has set up 3 at least layers of stoving units side by side along vertical direction on drying trolley 2's the frame 201 in this embodiment for hold the material. Specifically, referring to fig. 1 and 4, the drying unit includes a tray holder 204, a partition 205, and an air deflector 203. The tray support 204 is used for placing the tray 3, and can be composed of two or more support plates, similar to the drawer bottom support, so that the tray 3 can be pulled and pulled on the tray, and the air inlet is not influenced as much as possible under the condition of ensuring the strength.

In addition, the tray holders 204 are symmetrically arranged about the partition 205, that is, two rows of left and right drying units, or two rows of tray holders 204, are arranged on one drying vehicle 2, two trays 3 can be placed in parallel on the same layer, and the trays 3 are separated by the partition 205. The bottom of the tray 3 is provided with a vent hole which can lead the air flow to circulate.

The air deflector 203 is arranged below the tray support 204, the bottom surface of the air deflector 203 is in contact with the partition plate 205 of the next layer, so that for a drying unit, the air deflector 203, the partition plate 205 and the air deflector 203 below form a relatively closed area, air can be fed or exhausted only from two sides, and the areas on two sides of the partition plate 205 form a drying air duct 206 communicated through the air deflector 203 below. The air inlet 102 is communicated with one end of the drying air duct 206, the air outlet 104 is communicated with the other end of the drying air duct 206, the material tray 3 is placed on the material tray bracket 204, the material tray at the left air inlet end is marked as a material tray 3a, the material tray at the right air exhaust end is marked as a material tray 3b, transverse air enters from the position between the material tray 3a at one side of the partition plate 205 and the air deflector 203 above the material tray, the pressure is increased, then the transverse air penetrates through the material layer and enters the air duct surrounded by the air deflector 203 at the lower part from the air vent of the material tray 3a, and due to the fact that the pressure above the material tray 3b is small, air flow penetrates through the.

By adopting the structure, the drying units arranged up and down can be contacted with the circulating hot air at the same time, and the influence of the air flow humidity on the drying effect is small when the same air enters only through two material trays; circulating air passes through the material, hot air penetrates through the whole material layer, is not limited on the surface of the material, and is heated more uniformly; that is to say, this embodiment has combined horizontal air inlet and vertical air inlet to carry out the technique of drying, has improved drying efficiency greatly.

In addition, because air intake, air exit direct and the air inlet end in stoving wind channel are connected with the end of airing exhaust, and circulating hot air almost all is used for the material to dry, reduces the airflow with the contact of drying cart lateral wall, and the wind direction is also more stable, and hot-blast utilization ratio is higher, reduces the unnecessary loss, helps drying efficiency's improvement.

With reference to fig. 2, it should be noted that the present embodiment further includes a wind shielding assembly 105, where the wind shielding assembly 105 includes a wind shielding plate 1051 and a connecting shaft 1052, and the wind shielding plate 1051 is hinged to the lower side wall of the air inlet 102 of the box 1 through the connecting shaft 1052, so that the wind shielding plate 1051 can extend to the edge of the tray 3 after rotating. With reference to fig. 2 and 3, a wind shielding assembly is arranged at the air inlet, and a wind shielding plate in the wind shielding assembly is hinged to the lower side wall of the air inlet of the box body through a connecting shaft, so that the wind shielding plate can rotate, when the wind shielding plate rotates to be close to a vertical position, the wind shielding plate can avoid interference with a drying vehicle, and the drying vehicle can enter and exit from the cavity; when the drying vehicle is in the cavity, the wind shield is rotated to be close to the horizontal position, the gap can be blocked, and the wind discharged from the air inlet directly enters the material tray, so that the hot air utilization rate is effectively improved, and the processing efficiency is improved.

In addition, it should be noted that, if the frame 201 is supported by a plurality of vertically arranged pillars, in order to avoid the pillars arranged in the middle, an avoiding groove may be formed in the middle of the wind deflector in the length direction, or the wind deflector may be provided in a two-stage structure, which is not particularly limited.

Example 2

The chemical material of this embodiment is dried and is used choke formula stoving case, its basic structure is the same with embodiment 1, further: the minimum distance between the tray 3 on the drying vehicle 2 and the inner wall of the cavity of the box body 1 is less than the width of the air inlet 102. Thus, the wind deflector can not only block the gap, but also can rotate into the air inlet 102.

In addition, the air deflector 203 in this embodiment is arc-shaped and symmetrical about the partition 205, and the lowest point of the air deflector 203 is in contact with and connected to the partition 205.

Because the air deflector 203 is arranged in an arc shape, the space above the tray 3 is smaller as the position is closer to the position of the clapboard 205, and the pressure in the area is higher due to the existence of the clapboard 205; for the lower part of the material tray 3, the closer to the position of the partition plate 205, the larger the distance between the air deflector 203 and the ground of the material tray, and the larger the air duct space, thereby being more beneficial to the circulation of the circulating hot air.

Example 3

The chemical material of this embodiment is dried with choke formula stoving case, its basic structure is the same with implementation 2, and its improvement point lies in: the wind shielding assembly 105 further includes damping springs 1053 at both ends of the connecting shaft 1052, and the damping springs 1053 are used for providing a pushing force to the wind shielding plate 1051 in a direction toward the wind inlet 102.

Referring to fig. 3, in the non-use state, the wind deflector 1051 is pushed to a position close to the air inlet 102 by the urging force of the damper spring 1053; referring to fig. 2, during the drying operation, the outer end of the wind shield 1051 is put on the tray due to the airflow force of the hot wind, so as to shield the gap between the drying cart and the oven. Manual intervention is not needed, and the automation degree is improved.

Example 4

The chemical material of this embodiment is dried and is used choke formula stoving case, its basic structure is the same with implementation 3, its difference lies in: one sides of the air inlet 102 and the air outlet 104 close to the middle part of the box body 1 are inclined downwards, and the distance between the end surfaces of the air inlet 102 and the air outlet 206 is 5 mm.

Because the air inlet 102 and the air outlet 104 are located on the box body and the drying air duct 206 is located on the drying vehicle, it is necessary to ensure that the relative positions of the two are matched with each other. Set up the clearance into 5mm, can guarantee the normal business turn over of drying by the fire car on the one hand, on the other hand can make to dry by the fire car and have less clearance between air intake, the air exit, can not make hot-blast loss. The gap can be set according to the requirement due to different specifications of the equipment, and can be set to be 10mm or 15mm or other values according to the actual requirement without specific limitation.

In addition, because the air deflector 203 is arc-shaped, in order to facilitate air intake and reduce resistance, the air inlet 102 and the air outlet 104 can be arranged to be inclined downwards at one side close to the middle of the box body 1, and can be better matched with the drying air duct 206.

For the top drying unit, a drying air duct also needs to be formed, so a top cover plate 202 can be arranged on the top of the drying vehicle 2, and the top cover plate 202 and the air guide plate 203 have the same structure so as to cooperate with the uppermost drying unit to supply air.

Example 5

The chemical material of this embodiment is dried and is used choke formula stoving case, its basic structure is the same with embodiment 4, its difference lies in: the inner wall of the tray 3 parallel to one side wall of the partition plate 205 is obliquely arranged, and the oblique direction of the inner wall is deviated to the middle part of the tray 3; in connection with fig. 5, when used as a tray 3a, the inclined side walls are close to the partition 205; when used as a tray 3b, the sloped side walls are away from the partition 205.

For the inclination of the inner wall of the tray 3, the side wall can be directly inclined as shown in fig. 6, or the side wall can be vertical, and then the inner wall is beveled to form an inclined inner wall as shown in fig. 4, so that the aim of inclining the inner wall can be achieved.

As is well known, the material is mostly the graininess, has certain clearance between the material in the charging tray, nevertheless because the material has certain thickness, can pile up each other between the material, and to the material that is located the edge, because the existence of charging tray lateral wall, pile up the effect and for other regions, can have relatively great gap, and the air flow is great during the ventilation, also is so-called edge effect. For the synthetic resin to be processed in this embodiment, if the local air flow is large, on one hand, the air flow distribution is uneven, which is not beneficial to improving the processing efficiency; on the other hand, high temperature gas flow may coke the material and degrade the product quality.

In view of the above problems, in the embodiment, when the tray is used as the tray 3a, the inclined side wall is close to the partition plate 205, so that the air flow rate at the inner edge of the tray 3a is reduced; when the tray is used as the tray 3b, the inclined side wall is far away from the partition plate 205, so that the air exhaust quantity of the outer edge of the tray 3b is reduced, and the influence of the edge effect on the drying effect is reduced.

Example 6

The chemical material of this embodiment is dried and is used choke formula stoving case, its basic structure is the same with embodiment 5, its difference lies in: the main function of the tray 3 is to hold the materials and to ventilate, therefore, the bottom plate can be provided with a ventilation hole or directly made of a silk screen, and the ventilation hole is selected to be arranged in the embodiment.

It should be noted that, the above description mainly refers to the description of a single layer of drying units, the drying cart 2 in this embodiment includes 5 layers of drying units, two rows are provided on the left and right of each layer, each row includes 2 to 5 rows of drying units as seen from the side of the drying cart 2, taking 3 rows of drying units as an example, each layer has 6 drying units, and 6 trays can be placed therein.

The two ends of the drying trolley 2 are closed, and the material tray 3 is put and pushed onto the material tray bracket 204 from the two sides of the drying trolley 2. For the drying units in the same row between the layers, two adjacent rows of the drying units can be communicated with each other, and a partition plate can also be arranged to separate the drying units, and the drying units are not particularly limited.

In this embodiment, different drying units can be selectively separated from each other, as shown in fig. 7, two sides of the air deflector 203 in each drying unit have inclined side walls, so that different drying units are not affected by each other. If the length of the drying units is large, namely the material tray is long, the situation of lateral hot air disturbance is likely to exist, namely, the air flow moves among the multiple rows of drying units instead of directly passing through the material tray for circulation, and the air intake is not facilitated. After the drying units are separately arranged, the flowing direction of the circulating hot air can be ensured.

Further, the side walls are obliquely arranged and are inclined outwards, so that the edge air flow is less, and the influence of edge effect is reduced.

Example 7

The chemical material of this embodiment is dried and is used choke formula stoving case, its basic structure is the same with embodiment 6, its difference lies in: the bottom of the drying trolley 2 is provided with a roller, a track is arranged in the box body 1, and the roller is matched with the track. The roller is also a conventional arrangement in the field, and the roller can be directly arranged into a universal wheel, so that the drying vehicle can conveniently enter and exit.

Example 8

The chemical material of this embodiment is dried and is used choke formula stoving case, its basic structure is the same with embodiment 7, its difference lies in: this embodiment is provided with the carousel in the 1 outside of box, is provided with the track on the carousel, is located the back when the carousel, and the track can link up with 1 interior track of box on the carousel, makes the drying vehicle travel to the carousel along the track, through rotating the carousel, can make drying vehicle upset direction, and then conveniently feeds with one side. A positioning mechanism can be arranged on the turntable to control the rotation angle of the turntable to be 180 degrees.

If the direction does not need to be turned, the loading can be directly finished on one side, and the efficiency is higher. The structure of the baking oven of this embodiment with the partition 205 makes it impossible to complete the loading from one side, so that only the direction of the baking oven 2 can be adjusted. In order to achieve the purpose, only universal wheels are adopted, or the universal wheels are matched with the tracks, but in any scheme, after the direction is turned, the drying oven is pushed into the box body, and at the moment, the drying oven needs to be positioned and aligned. And adopt the carousel structure in this embodiment, can accomplish the automobile body location after the direct rotation, the drying cart push into the box can, simple structure, convenient to use.

The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, without departing from the inventive spirit of the present invention, the person skilled in the art should also design the similar structural modes and embodiments without creativity to the technical solution, and all shall fall within the protection scope of the present invention.
