Detailed Description

The first embodiment is as follows:

as shown in fig. 1 to 4, the utility model discloses an oven body 1 is equipped with in oven body 1 and puts thing box 3, is being equipped with sealed lid putting 3 upper portion openings of thing box, puts thing box 3 and includes that the epicoele places district and cavity of resorption absorption district, and the epicoele is placed district and cavity of resorption absorption district and is passed through net 10 intercommunication, is provided with partition box 5 at cavity of resorption absorption district internal rotation, and partition box part is located puts the thing box external part and is located and put the thing box, partition box 5 with put the equal sealed rotation of thing box 3 contact segment and be connected.

Oven body 1 one side opening part is equipped with sealing door 6, and both sides wall is equipped with backup pad 2 in oven body 1, is equipped with a plurality of brackets 4 between backup pad 2, is equipped with engaging lug 8 at bracket 4 both sides border, and engaging lug 8 is connected with backup pad 2 through curved bar 9, puts thing box 3 and places on bracket 4. Two pairs of backup pads 2 are symmetrically arranged on two side walls in the oven body 1, a plurality of jacks 7 are sequentially arranged from top to bottom along the length direction of the backup pads 2, the jacks 7 are used for connecting a curved bar 7 and a bracket 4, the bracket 4 is dragged to move up and down between the backup pads 2 to adjust the interval between the two brackets 4, then the connecting lugs are connected with the jacks 7 through the curved bar 7, and the bracket 4 is fixed, so that the storage boxes 3 with different sizes and volumes can be used.

The partition box 5 is the partition box of carousel formula, partition box 5 is inside to be divided into the fan-shaped district that holds of multiunit variation in size with partition box 5 through a support stake 11 and a plurality of baffle 12, support stake 11 and be the cylinder formula, two symmetrical fan-shaped regional sizes of every group are the same in the partition box 5, and sealed with baffle 12 on the part fan-shaped regional upper portion of will symmetry, baffle 12 is sealed to be in order to place the district bottom plate contact increase with putting 3 epicoeles of thing box in the partition box rotation process, prevent that gas from getting rid of.

The storage box 3 is made of PC plates or glass and the like, and the PC plates or the glass have good heat transfer performance and also have the advantages of high temperature resistance, light transmission, easiness in processing and the like.

Because the trimethylchlorosilane and the water remained on the surface of the aerogel in the previous process are hydrolyzed with water to generate hydrogen chloride gas in the process of drying the aerogel. The device is through putting into caustic soda flakes or quick lime in separating box 5 in half the region, make it and hydrogen chloride gas contact reaction through net 10 and accomplish the absorption to hydrogen chloride gas, if need change caustic soda flakes or quick lime midway, add in the separating box 5 that is located to put thing box 3 outside, then rotate separating box 5, the district that holds that makes and holds new caustic soda flakes or quick lime rotates the net lower part and reacts with hydrogen chloride gas, sealed separating box 5's region and the box wall contact of separating box front end this moment, prevent hydrogen chloride and discharge, the caustic soda flakes or the quick lime that react this moment are rotated to the outside that holds box 5, and take out it.

Example two

The difference between the first embodiment and the second embodiment is that the partition box 5, if the aerogel is replaced by other substances to be dried, as shown in fig. 5, the partition plate 12 in the partial area of the upper part of the partition box is taken out as required, if one or more harmful gases are generated during the drying process, the absorbing medium is put into the areas with different sizes in the partition box 5 according to the amount of the harmful gases generated by the chemical formula, and the medium with the most generated gas is put into the area with large internal volume in the partition box 5 for absorbing the gas, and the absorbing medium is gradually decreased. Therefore, the harmful gas can be effectively absorbed, the medium is saved, and the waste is prevented. The medium is selected according to the type of gas to be absorbed, so that the aim of drying can be fulfilled, harmful gas can be effectively absorbed, and leakage, corrosion of an oven and air pollution are prevented.

The utility model discloses at the during operation, will put thing box 3 upper seal lid and open, and the aerogel that will last process has trimethylchlorosilane and water is put into putting thing box 3, and cover sealed lid, through the height of putting thing box 3, drag bracket 4 and reciprocate the interval between two brackets of adjustment 4 between backup pad 2, then be connected engaging lug and jack 7 through curved bar 7, will put thing box 3 and put on bracket 4, add caustic soda or quick lime in putting 3 outer spacer box 5 of thing box, then rotate spacer box 5, make caustic soda or quick lime rotate the hydrogen chloride gas reaction that the water hydrolysis of net lower part and trimethylchlorosilane generated, and close the sealing door, only need put into caustic soda or quick lime in the half region of spacer box 5 at every turn, half adds when changing. Put through oven power this moment, press the start button fan and start, press the heating and start, ammeter work settlement temperature, set for the constant temperature time, the temperature will be transmitted to the inside of putting thing box 3 this moment, play the drying effect to the aerogel, it has absorbed to reach predetermined time and has shown hydrogen chloride gas, if need change caustic soda or quick lime midway, externally hold box 5 and put into new caustic soda or quick lime in holding the district, then rotate and make it react with hydrogen chloride gas to the net lower part, caustic soda or quick lime that will react this moment take out.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
