The following describes a drying box for drying pole pieces in conjunction with fig. 1 to 4.

The embodiment of the utility model provides a pair of stoving case for drying pole piece, include: a housing 1 and a filter 2.

Wherein, be equipped with fan 11 and drying device in the casing 1, drying device is provided with wind chamber 12, and wind chamber 12 communicates with the air outlet of fan 11 for air current direction pole piece that forms fan 11.

The filter 2 is arranged in a channel communicated with the air cavity 12 at the air outlet of the fan 11, the side wall of the shell 1 is provided with a plug-in port 3, and the filter 2 is detachably inserted in the plug-in port 3. In some embodiments, the filter 2 may alternatively be a filter with a multi-layer structure, which may be a material layer with a filtering function on gas, such as a filter screen, a dust collector, a filter screen of granular activated carbon, etc., for removing fine particles in air, so that the pole piece is not polluted by granular dust.

The stoving case that this embodiment provided, when using, filter 2 sets up in the passageway of the air outlet of fan 11 and wind chamber 12 intercommunication to filter the foreign matter such as the dust piece in the gas, prevent that the foreign matter from blowing out along with gas in entering wind chamber 12 and gluing and influencing finished product quality on the pole piece surface. The filter 2 is detachably inserted into the shell 1 through the insertion port 3, the filter 2 can be taken out without opening the shell 1, the maintenance time of the filter 2 is saved, and the replacement and cleaning efficiency of the filter 2 is improved.

In some embodiments, the casing 1 may adopt, but is not limited to, a cube structure with a regular shape, and the fan 11 and the drying device are oppositely disposed in two regions of the inner space of the casing 1, so as to improve the space utilization rate and reduce the space occupied by the drying box.

Referring to fig. 1, in the embodiment of the present invention, the air collecting chamber 13 is further included, the air collecting chamber 13 is disposed in the casing 1, and one end of the air collecting chamber 13 is communicated with the air outlet of the fan 11 for accommodating the air blown out by the fan 11. The filter 2 is arranged at one end of the air collecting cavity 13 close to the air outlet of the fan 11; one side of the air collection cavity 13 is communicated with the air cavity 12. In some embodiments, the air collecting cavity 13 is a closed channel having an inlet and an outlet, the inlet is opened at one end of the air collecting cavity 13 corresponding to the fan 11, and the outlet is opened at one side corresponding to the air cavity 12, so as to guide the air blown out from the air outlet of the fan 11 into the air cavity 12.

So set up, through set up collection wind chamber 13 in casing 1, be favorable to collecting wherein with 11 air outlets of fan gaseous whole gas that blow off, gaseous collection wind chamber 13 is collected the back and is leaded to wind chamber 12 again in, can avoid gaseous excessive, improves the utilization to gas.

Referring to fig. 2, in the embodiment of the present invention, the insertion port 3 is disposed on the sidewall of the wind collecting cavity 13, and the filter 2 is installed in the wind collecting cavity through the insertion port 3.

Referring to fig. 2 and 3, in a further embodiment, a sliding mounting frame 131 is provided in the air collection chamber 13, the sliding mounting frame 131 corresponds to the interface 3, and the filter 2 is slidably connected in the sliding mounting frame 131. So set up, through set up a sliding mounting frame 131 in collection wind chamber 13 to correspond with interface 3, can play the direction and the fixed action to filter 2, filter 2's one end gets into in interface 3 along the track that sliding mounting frame 131 formed to inside the slip of casing 1, finally fixes a position filter 2 in casing 1.

It should be noted that the sliding mounting frame 131 only fixes the filter 2 in the housing 1, and both ends of the sliding mounting frame 131, which are opposite to the air outlet of the blower 11, are hollow structures, so that the air entering and exiting the filter 2 is not affected; preferably, the end face of the sliding mount 131 is the best way to mount the filter 2 when it is perpendicular to the air blown by the fan 11.

In some embodiments, structures such as a slide rail and a slide groove can be further arranged in the air collecting cavity 13 to achieve the purpose of guiding and positioning the filter 2 in the installation process, and the air collecting cavity is not limited to the structure of the sliding installation frame 131, and all the structures capable of achieving the above effects are in the protection range of the present invention.

Referring to fig. 3, in an embodiment of the present invention, the joint of the sliding mounting frame 131 and the filter 2 is provided with a sealing strip 4. Specifically, sealing strip 4 sets up in the border gap department of sliding mounting frame 131, realizes that filter 2 can with sliding mounting frame 131 sealing contact after pegging graft in casing 1, the condition of gas overflow leakage can not appear.

Referring to fig. 3, in a further embodiment, a cover plate 21 is disposed at one end of the filter 2 outside the socket 3, a handle 22 is disposed at the outside of the cover plate 21, the inside of the cover plate 21 is hermetically connected with the socket 3, and the area of the cover plate 21 is larger than that of the socket 3. So set up, set up apron 21 through the outer end at filter 2, can prevent that 3 departments of interface from appearing the condition that gaseous is excessive to with the inboard and 3 sealing connection of interface of apron 21, improve sealed effect, specifically can be, set up sealing strip 4 in the outer lane of interface 3, or also set up sealing strip 4 at the inboard border of apron 21, realize the leakproofness contact of the two. In addition, the filter 2 can be conveniently drawn out from the shell 1 from the outside of the shell 1 through the handle 22 on the outer side of the cover plate 21, and the filter can be replaced, cleaned and maintained, so that the time is saved, and the efficiency is improved.

Referring to fig. 2, in an embodiment of the present invention, the present invention further includes a heater 14, and the heater 14 is disposed between the air outlet of the fan 11 and the filter 2, and is used for heating the airflow formed by the fan 11.

In some embodiments, the heater 14 is an electric heater, which may be an electromagnetic heater or a resistive heater, and is installed in the air collecting cavity 13 to heat the air blown out from the air outlet of the fan 11, so as to provide high-temperature air to the air cavity 12, thereby improving the drying efficiency of the pole piece.
