DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with embodiments. The embodiments described are only a portion of the embodiments of the present invention and are not intended to be all embodiments. Based on the embodiments of the present invention, other embodiments obtained by persons of ordinary skill in the art without creative work are all within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 4 As shown, this embodiment discloses a production device, specifically a quicksand-type potassium perchlorate production device, which is used to stir and filter quicksand-type potassium perchlorate; wherein the device includes a centrifuge, a centrifugal high-level tank, a mixing device, a screening device, and an immersion tank; the mixing device includes: a barrel 101, a stirring mechanism 102, a sealing cover mechanism 103, and a discharge port 104; the stirring mechanism 102 is connected to the barrel 101, the sealing cover mechanism 103 is sealed and installed on the inlet of the barrel 101, and the discharge port 104 is opened at the bottom of the barrel 101; the stirring mechanism 102 is used to mix multiple materials inside the barrel 101;

[0028] The screening device includes: a screening trough 105, a lower bin 106, a filter 107 and a vibration motor 108. The screening trough 105 is installed at the bottom of the barrel 101, and the discharge port 104 is connected to the screening trough 105. The discharge port 104 is used to open or close; the lower bin 106 is installed at the lower opening of the screening trough 105, the filter 107 is installed inside the screening trough 105, the height of the discharge port 104 is higher than the filter 107, and the vibration motor 108 is installed on the screening trough 105;

[0029] The inlet end of the soaking tank is connected to the outlet end of the lower hopper 106, and the outlet end of the soaking tank is connected to the centrifugal high-level tank, which is used to store the material in the soaking tank. The outlet end of the centrifugal high-level tank is connected to a centrifuge, which is used to separate the soaked material into dry and wet parts.

[0030] The utility model mainly comprises a centrifuge, a centrifugal high-level tank, a mixing device, a screening device and a soaking tank; in actual use, the staff first adds 65% of the volume of soft water into the soaking tank, and then adds SDS, TX10 and KF865 in a ratio of 1:1:1, and heats the soaking tank to dissolve the blocky potassium perchlorate inside the soaking tank to form potassium perchlorate wet crystals; then the potassium perchlorate wet crystals are poured into the barrel 101, and a nano-scale hydrophobic powder anti-caking agent is added into the barrel 101, and then the stirring mechanism 102 is driven to fully stir and mix the potassium perchlorate wet crystals and the nano-scale hydrophobic powder anti-caking agent inside the barrel 101, and the stirred potassium perchlorate wet crystals pass through the discharge port 104. The potassium perchlorate wet crystals enter the screening trough 105, and the vibration motor 108 is started at the same time. After the vibration of the vibration motor 108, the potassium perchlorate wet crystals are screened through the filter screen 107, and finally discharged from the lower hopper 106 and passed into the soaking tank; then the potassium perchlorate wet crystals in the soaking tank are stirred again for 10-15 minutes. After the stirring is completed, the stirred potassium perchlorate wet crystals in the soaking tank are passed into the centrifugal high-level tank for temporary storage. After a certain amount of potassium perchlorate wet crystals are stored, the potassium perchlorate wet crystals in the centrifugal high-level tank are passed into the centrifuge for centrifugation. The liquid formed after centrifugation is returned to the soaking tank, and the solids are collected. Finally, the collected solids are dried to form quicksand potassium perchlorate. The stirring mechanism can fully stir the potassium perchlorate wet crystals and the nano-hydrophobic powder anti-caking agent to make the potassium perchlorate wet crystals less likely to agglomerate. The screening trough 105 can also filter the lumpy potassium perchlorate wet crystals. During the vibration of the vibration motor 108, some large lumps of potassium perchlorate wet crystals can be disintegrated into small lumps and powdered potassium perchlorate wet crystals, thereby further improving the anti-caking effect.

[0031] It should be noted that SDS, TX10 and KF865 are all dispersants in the prior art.

[0032] In some embodiments, the stirring mechanism 102 includes a motor 109, a rotating shaft 110 and a stirring blade 111. The fixed end of the motor 109 is installed on the barrel 101, and the movable end is fixedly connected to the rotating shaft 110. The rotating shaft 110 is rotatably installed on the barrel 101. The output shaft of the motor 109 is connected to the rotating shaft 110 and is used to drive the rotating shaft 110 to rotate. The stirring blade 111 is fixedly installed on the rotating shaft 110.

[0033] During actual use, when it is necessary to stir the potassium perchlorate wet crystals, it is necessary to control the motor 109 to rotate. After the motor 109 rotates, it drives the rotating shaft 110 to rotate. After the rotating shaft 110 rotates, it drives the stirring blade 111 to rotate. After the stirring blade 111 rotates, it drives the potassium perchlorate wet crystals and the nano-scale hydrophobic powder anti-caking agent to be fully stirred and mixed, so that the potassium perchlorate wet crystals are affected by the anti-caking agent to avoid agglomeration.

[0034] In some embodiments, the motor 109 is connected to the rotating shaft 110 via a reducer 112 .

[0035] In actual use, the speed reducer 112 can effectively control the rotation speed of the shaft 110 , and there is no need to configure the model of the motor 109 to match the rotation speed of the shaft 110 , which is more convenient to use.

[0036] In some embodiments, the sealing cover mechanism 103 includes a cover body 113 and a cylinder 114 arranged on both sides of the cover body 113. The cover body 113 is hinged on the barrel 101, the cylinder body of the cylinder 114 is hinged to the barrel 101, and the rod body of the cylinder 114 is hinged to the cover body 113.

[0037] During actual use, when it is necessary to open the cover body 113, the staff controls the extension of the cylinder 114. At this time, the rod body of the cylinder 114 slides out from the cylinder body of the cylinder 114, and then the rod body of the cylinder 114 extends to support the cover body 113, so that the cover body 113 rotates around the barrel 101, thereby opening the barrel 101; conversely, when it is necessary to close the cover body 113, it is necessary to control the originally extended cylinder 114 to retract. After the cylinder 114 retracts, it pulls the cover body 113 to close, thereby completing the closing of the barrel 101.

[0038] In some embodiments, a hinge portion 115 is provided on the cover body 113 , and the rod portion is hinged to the cover body 113 via the hinge portion 115 .

[0039] In actual use, the hinge portion 115 can make the rotation between the cover body 113 and the barrel 101 smoother.

[0040] In some embodiments, a stepped groove 116 is provided at the opening of the barrel 101 , and a sealing gasket is provided below the cover body 113 . When the cover body 113 is closed, the sealing gasket contacts the stepped groove 116 to form a seal.

[0041] During actual use, when the cover body 113 is closed, the sealing gasket under the cover body 113 is placed in the stepped groove 116, and the cylinder 114 pulls the cover body 113 so that the sealing gasket fits tightly against the upper end surface of the stepped groove 116, thereby completing the sealing of the cover body 113, which is beneficial to prevent potassium perchlorate from leaking.

[0042] In some embodiments, a workbench 117 is provided below the barrel 101 , and the screening trough 105 and the motor 109 are both installed on the workbench 117 .

[0043] In actual use, the purpose of providing the workbench 117 is to install the screening trough 105 and the motor 109 .

[0044] In some embodiments, the discharge port 104 is connected to the feed port on the side wall of the screening trough 105 through a discharge channel 118 . The discharge channel 118 is inclined, and a gate is provided on the discharge port 104 .

[0045] During actual use, it is necessary to first slightly open the gate so that the material inside the barrel 101 falls into the discharge channel 118 due to gravity. Since the discharge channel 118 is inclined, the material will enter the screening trough 105 along the inclined discharge channel 118.

[0046] In some embodiments, a plurality of brackets 119 are provided on the screening trough 105 , and each of the brackets 119 is provided with a vibration motor 108 .

[0047] In actual use, the function of the vibration motor 108 is to make the screening trough 105 vibrate, thereby screening the potassium perchlorate wet crystals, and the larger potassium perchlorate wet crystals are re-entered into the soaking tank for dissolution.
