Description

Technical Field

[0001] The utility model relates to the technical field of zinc peroxide purity detection, in particular to purity detection equipment for high-purity zinc peroxide production. Background Art

[0002] In the production of zinc peroxide, it is mainly precipitated from an alkaline solution of zinc salt and hydrogen peroxide, but the purity of this zinc peroxide is insufficient. A better preparation method is to react an ether solution of zinc oxide or diethyl zinc with concentrated hydrogen peroxide. Regardless of the preparation method, the high-purity zinc peroxide obtained needs to be tested for purity after production to avoid the production of zinc peroxide with poor purity due to operational errors and other reasons. Therefore, we urgently need a purity testing equipment for the production of high-purity zinc peroxide. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention provides a purity detection device for the production of high-purity superzinc oxide, which solves the problems raised in the above-mentioned background technology.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a purity detection device for high-purity super-zinc oxide production, comprising a detection tank and supporting legs distributed on four sides of the detection tank, a heating chamber provided in the detection tank, a detection device provided in the heating chamber in the detection tank, the detection device comprising a purity detection unit and an airflow pressurizing unit, the purity detection unit being installed in the upper area of the detection tank, and the airflow pressurizing unit being installed in the lower area of the detection tank;

[0005] The purity detection unit includes a flip cover installed on the top of the detection tank, the flip cover is connected to the detection tank in an opening and closing manner, an oxygen content measuring instrument is installed at a limit position at the top of the flip cover, a detection tube is detachably connected to the top of the oxygen content measuring instrument, the other end of the detection tube is connected to a two-way tube, and the other two ends of the two-way tube respectively pass through the corresponding limit plates fixedly installed on the flip cover to the heating chamber of the detection tank.

[0006] The gas inside the detection tank is emptied in advance and the detection tank is cleaned to avoid the presence of other reactants. At this time, the heating interlayer set on the inner wall of the detection tank begins to heat up, the heating chamber begins to heat up, and the zinc peroxide in the detection tank begins to heat up. When zinc peroxide is heated alone above ℃, it will quickly decompose into zinc oxide and oxygen. Therefore, the airflow and pressurization generated by the airflow pressurization unit will prompt the oxygen to quickly pass through the double-way pipe on the top of the detection tank into the detection tube, and finally the oxygen concentration and content are read from the oxygen content meter, and the concentration of zinc peroxide is calculated according to the total mass of zinc peroxide in the detection tank.

[0007] A further improvement of the technical solution of the present utility model is that: a placement tube is provided at the bottom of the flip cover, and diffusion holes are arranged in a circle-centered array on the placement tube, and a placement plate for placing zinc peroxide is provided at the bottom of the placement tube, and arc blocks are symmetrically provided at both ends of the placement plate, and a rod inserted into the flip cover socket is limited in the two arc blocks.

[0008] A further improvement of the technical solution of the present utility model is that in order to avoid damage to the zinc peroxide due to excessive air pressure inside the detection tank and to avoid affecting the purity detection of zinc peroxide, a bolt is provided at the circular part of the flip cover, a pull ring is provided on the top of the bolt, and the bolt is movably connected to the flip cover.

[0009] A further improvement of the technical solution of the present utility model is that: the airflow pressurization unit includes a driving shaft rotatably mounted on the bottom of the detection tank, the driving shaft is connected to the driving motor through a coupling, a driving gear is keyed on the driving shaft, and a driven gear is engaged with each end of the driving gear. The two driven gears are respectively located on a screw rod rotatably mounted on the bottom of the detection tank, and the nuts of the two screw rods are respectively fixedly connected to corresponding connecting rods. The two connecting rods pass through the bottom of the detection tank and are fixedly connected to a pressure plate.

[0010] The drive motor in the air flow pressurization unit drives the active gear to start rotating in conjunction with the driven gear. After the torque is transmitted to the screw, the connecting rod rises and falls due to the threaded connection of the nut, thereby squeezing the internal gas during the rising process of the pressurization plate, allowing oxygen to quickly enter the oxygen content meter, and cooperating with the airflow blades on the drive shaft to accelerate the airflow and improve detection efficiency.

[0011] A further improvement of the technical solution of the present invention is that in order to accelerate the diffusion rate of oxygen during the heating process, air flow blades are provided on the axis of the driving shaft located in the heating chamber of the detection tank, and the pressure plate slides on the driving shaft.

[0012] A further improvement of the technical solution of the present invention is that, in order to prevent external gas from escaping into the tank body or oxygen from overflowing from the detection tank, seals are provided at the location where the drive shaft passes through the detection tank and at the locations where the two connecting rods pass through the detection tank.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1-Figure 4 , this utility model provides three technical solutions:

[0024] Example 1:

[0025] A purity detection device for high-purity superzinc oxide production includes a detection tank 101 and supporting legs 102 distributed on four sides of the detection tank 101 for supporting the detection tank 101. The detection tank 101 is provided with a heating chamber. The detection device is provided in the heating chamber of the detection tank 101. The detection device includes a purity detection unit and an airflow pressurization unit. The purity detection unit is installed in the upper area of the detection tank 101, and the airflow pressurization unit is installed in the lower area of the detection tank 101.

[0026] The purity detection unit includes a flip cover 201 installed on the top of the detection tank 101, and the flip cover 201 is connected to the detection tank 101 for opening and closing. An oxygen content meter 202 is installed at a limit position on the top of the flip cover 201. A detection tube 203 is detachably connected to the top of the oxygen content meter 202. The other end of the detection tube 203 is connected to a two-way tube 204. The other two ends of the two-way tube 204 respectively pass through the corresponding limit plates 205 fixedly installed on the flip cover 201 to the heating chamber of the detection tank 101.

[0027] In this embodiment, the model of the oxygen content meter 202 is ERUN-QZ9100S. The specific detection process is as follows: the gas inside the detection tank 101 is emptied in advance, and the detection tank 101 is cleaned to avoid the presence of other reactants. At this time, the heating barrier arranged on the inner wall of the detection tank 101 starts to heat, the heating chamber starts to heat up, and the zinc peroxide in the detection tank 101 starts to heat. When zinc peroxide is heated alone above 150°C, it quickly decomposes into zinc oxide and oxygen. Therefore, the airflow and pressurization generated by the airflow pressurization unit prompt the oxygen to quickly pass through the double-way pipe 204 at the top of the detection tank 101 into the detection tube 203, and finally the oxygen concentration and content are read from the oxygen content meter 202, and the concentration of zinc peroxide is calculated based on the total mass of zinc peroxide in the detection tank 101.

[0028] Example 2:

[0029] Based on Example 1:

[0030] A placement tube 206 is provided at the bottom of the flip cover 201, and escape holes 207 are arranged in a circular array on the placement tube 206. A placement plate 208 for placing zinc peroxide is provided at the bottom of the placement tube 206. Arc blocks 209 are symmetrically provided at both ends of the placement plate 208. The two arc blocks 209 are limited by an insertion rod 210 inserted into the socket of the flip cover 201.

[0031] In order to prevent the zinc peroxide from being damaged due to excessive air pressure inside the detection tank 101 and to avoid affecting the purity detection of the zinc peroxide, a bolt 211 is provided at the circular part of the flip cover 201, and a pull ring 212 is provided on the top of the bolt 211. The bolt 211 is movably connected to the flip cover 201.

[0032] Example 3:

[0033] On the basis of Example 1 and Example 2: the air flow pressurization unit includes a drive shaft 301 rotatably mounted on the bottom of the detection tank 101, the drive shaft 301 is connected to the drive motor 302 through a coupling, a driving gear 303 is keyed on the drive shaft 301, and a driven gear 304 is engaged at each end of the driving gear 303. The two driven gears 304 are respectively located on a screw rod 305 rotatably mounted on the bottom of the detection tank 101, and the nuts of the two screw rods 305 are respectively fixedly connected to corresponding connecting rods 306. The two connecting rods 306 pass through the bottom of the detection tank 101 and are fixedly connected to a pressure plate 307.

[0034] In this embodiment, the driving motor 302 in the air flow pressurization unit drives the driving gear 303 to start rotating in conjunction with the driven gear 304. After the torque is transmitted to the screw 305, the connecting rod 306 follows the rise and fall due to the threaded connection of the nut, thereby squeezing the internal gas during the rise of the pressurization plate 307, allowing oxygen to quickly enter the oxygen content meter 202, and cooperating with the air flow blades 308 on the drive shaft 301 to accelerate the air flow and improve the detection efficiency.

[0035] In order to speed up the diffusion of oxygen during the heating process, an air flow blade 308 is provided on the axis of the driving shaft 301 located in the heating chamber of the detection tank 101 , and the pressure plate 307 slides on the driving shaft 301 .

[0036] In order to prevent external gas from escaping into the tank body or oxygen overflowing from the detection tank 101 , seals are provided at the locations where the drive shaft 301 passes through the detection tank 101 and at the locations where the two connecting rods 306 pass through the detection tank 101 .

[0037] At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0038] During use, the internal gas of the detection tank 101 is emptied in advance, and the detection tank 101 is cleaned to avoid the presence of other reactants. At this time, the heating interlayer arranged on the inner wall of the detection tank 101 starts to heat, the heating chamber starts to heat up, and the zinc peroxide in the detection tank 101 starts to heat. When zinc peroxide is heated alone above 150°C, it quickly decomposes into zinc oxide and oxygen. The drive motor 302 drives the driving gear 303 to start rotating in conjunction with the driven gear 304. After its torque is transmitted to the screw rod 305, the connecting rod 306 follows the rise and fall due to the threaded connection of the nut, thereby squeezing the internal gas during the rise of the pressure plate 307, so that oxygen quickly enters the oxygen content meter 202, and cooperates with the air flow blade 308 on the drive shaft 301 to accelerate the air flow, so that oxygen quickly passes through the two-way pipe 204 at the top of the detection tank 101 into the detection tube 203, and finally reads the oxygen concentration and content from the oxygen content meter 202, and calculates the concentration of zinc peroxide based on the total mass of zinc peroxide in the detection tank 101.
