Embodiment 1

[0043] combine figure 1 A circulating hot air drying box for processing varnish powder in this embodiment includes a box body 1 and a drying car 2. The air inlet and moisture outlet of the box body 1 in this embodiment can adopt conventional designs, as long as Able to enter the wind laterally, without specific restrictions. An air inlet 101 is arranged on the left side of the box body 1 , and the air inlet 101 is arranged in a vertical direction, and an air inlet 102 is connected to the air inlet 101 . The air inlet 102 connects the air inlet channel with the inner cavity of the box, and the air inlet 102 is arranged horizontally, and there are a plurality of vertically spaced ones for allowing the drying wind to enter laterally to form a plurality of air inlets.

[0044] An air exhaust duct 103 is provided on the right side of the box body 1 , and transverse air exhaust outlets 104 are arranged at intervals on the air exhaust duct 103 . The air outlet 104 has the same arra...

Embodiment 2

[0051] A circulating hot air drying box for processing varnish powder in this embodiment, its basic structure is the same as that of Embodiment 1, the difference is that: the air deflector 203 in this embodiment is arc-shaped, and with respect to the partition The plate 205 is symmetrical, and the lowest point of the air guide plate 203 is in contact with the partition plate 205 .

[0052] Since the air deflector 203 is set in an arc shape, the closer to the position of the partition 205, the smaller the space above the tray 3, and due to the existence of the partition 205, the pressure in this area is relatively high; while for the bottom of the tray 3 , the closer to the partition 205, the greater the distance between the air deflector 203 and the ground of the tray, and the greater the space of the air duct, which is more conducive to the circulation of hot air circulation.

Embodiment 3

[0054] A circulating hot air drying box for processing varnish powder in this embodiment, its basic structure is the same as that of Embodiment 2, the difference is that: the air inlet 102 and the air outlet 104 are close to the side of the middle of the box body 1 It is inclined downward, and the distance between its end face and the inlet end face of the drying air duct 206 is 5mm.

[0055] Since the air intake effect must be ensured, and 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 car, it is necessary to ensure that the relative positions between the two can cooperate with each other. Setting the gap to 5mm, on the one hand, can ensure the normal entry and exit of the drying car, and on the other hand, can make a small gap between the drying car and the air inlet and exhaust port, so that the hot air will not be lost. Due to the different specifications of the equipment, the gap can be set accord...

Abstract

The invention discloses a circulation hot air drying box used for processing glazing powder, and belongs to the technical field of drying equipment. The circulation hot air drying box comprises a box body and a drying vehicle, an air inlet flue and an air outlet flue are arranged in the box body, transverse air inlets are formed in the air inlet flue at intervals, and transverse air outlets are formed in the air outlet flue at intervals; a frame of the drying vehicle is provided with at least three layers of drying units in the vertical direction in parallel, the drying units comprise material disc supports, separating plates and air guide plates, the material disc supports are symmetrically arranged with respect to the separating plates and are used for containing material discs, and the air guide plates are arranged below the material disc supports, and drying air flues for communicating two-side zones of the separating plates are formed; the air inlets are communicated with one ends of the drying air flues, and the air outlets are communicated with the other ends of the drying air flues. According to the circulation hot air drying box, by improving the upper air inlet manner of the drying vehicle, materials in the material discs can be evenly heated, the materials on each layer are in direct contact with circulated fresh air, the needed time is short, and the drying efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of drying equipment, more specifically, to a circulating hot air drying box for processing varnish powder. Background technique [0002] The varnish powder, also known as melamine varnish resin, is obtained by reacting formaldehyde and melamine as raw materials. Because no pulp is added during production, it is commonly known as "fine powder"; it is used to sprinkle some on the surface when pressing tableware to increase the surface brightness and make the tableware more beautiful and generous. [0003] At present, the processing technology of varnish powder mainly includes four stages: [0004] 1) Reaction section: add melamine and formaldehyde into the reaction kettle in proportion, and carry out polycondensation reaction at 70-75°C to generate melamine-formaldehyde synthetic resin. [0005] 2) Aging section: Put the synthetic material in a plastic box to age for a period of time, and then put it into a ...
