Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of capacitor production, in particular to an internal drying rack of a rectangular capacitor shell. Background Art
[0002] The capacitor is composed of an outer shell and an inner core. When the inner core is filled and placed, its inner wall needs to be dried by blowing hot air. However, due to the single-tube structure of the drying spray gun, this drying method is not conducive to the discharge of water and other dust during drying, thus affecting the drying effect. In order to facilitate drying, the outer shell is usually placed on a table with its opening facing upward, which is not conducive to the discharge of water vapor. Utility Model Content
[0003] The utility model provides a rectangular capacitor shell internal drying rack to solve the above-mentioned shortcomings of the prior art, facilitates the drying operation of the capacitor shell, and has strong practicality.
[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:
[0005] A rectangular capacitor shell internal drying rack comprises a bottom plate, a pair of U-shaped tubes are installed on the bottom plate, and a plurality of air holes are opened in the transverse sections of the U-shaped tubes. The U-shaped tubes not only support the shell, but also can blow hot air into the shell, so as to facilitate the drying of the shell. In the drying process, the opening of the shell faces downward, so as to facilitate the discharge of water vapor and improve the drying effect and efficiency.
[0006] A spring is sleeved on the vertical section of the U-shaped tube, and a rectangular frame is provided at the upper end of the spring. An air outlet plate is provided in the rectangular frame, and a plurality of air outlet holes are opened on the air outlet plate. The vertical section of the U-shaped tube passes through the rectangular frame, and a lower box is provided on the lower wall of the rectangular frame. The lower box is located directly below the air outlet plate, and an air outlet pipe is connected to the lower box. The lower end of the air outlet pipe passes through the bottom plate. The lower box is used to collect the discharged water vapor and hot air flow, and the water vapor is prevented from entering the shell again by collecting and discharging. And through the setting of the spring, when the capacitor is placed, the upper force provided by it is convenient to seal the lower end of the capacitor. Of course, a soft rubber pad needs to be set on the upper wall of the rectangular frame for sealing.
[0007] Two pairs of convex seats are installed on the bottom plate, and movable rods are passed through the convex seats. The inner ends of the movable rods are bent upward with vertical rods, and the upper ends of the vertical rods are bent inward with clamping rods. The movable clamping rods can be clamped on the upper end of the shell, thereby fixing the shell to prevent the capacitor from moving upward during drying.
[0008] Furthermore, the upper ends of the U-shaped tubes are connected to a transverse tube, which is provided with a plurality of holes. The holes on the transverse tube and the vent holes on the U-shaped tube are both arranged on the side, and this arrangement avoids blockage when the housing is closely attached to the transverse tube.
[0009] Furthermore, a filter plate is passed through the lower box, and a desiccant is filled in the filter plate to avoid absorbing water vapor during drying, so as to prevent the water vapor from entering the interior of the shell for a second time.
[0010] Furthermore, an end plate is provided at one end of the filter plate, and a pair of U-shaped slots are respectively provided on the upper and lower sides of the end plate, and a positioning rod is inserted into the U-shaped slot, and a U-shaped plate is provided on the positioning rod at the same height, and the U-shaped plate is installed on the lower box by screws. By fixing the U-shaped plate, it is convenient to replace and fix the filter plate.
[0011] Furthermore, a concave rod is provided at the other end of the clamping rod on the same side to facilitate the movement of the clamping rod.
[0012] Furthermore, a blocking rod is provided between the clamping rods on the same side, so as to further ensure the limiting effect of the housing through the blocking rod.
[0013] The advantages of the above technical solution are:
[0014] The utility model facilitates the drying operation of the rectangular capacitor shell and improves the drying effect. BRIEF DESCRIPTION OF THE DRAWINGS
