Description

Technical Field

[0001] The invention relates to the technical field of producing potassium perchlorate, in particular to a quicksand type potassium perchlorate production device. Background Art

[0002] Quicksand potassium perchlorate is an improved potassium perchlorate product whose particle size and fluidity are specially optimized to meet the high requirements of modern industrial and military applications. In the production process of traditional potassium perchlorate, problems of particle aggregation and poor fluidity are often faced, which not only affects the processing efficiency but also increases the safety risks in use. In order to solve these problems, the production technology of quicksand potassium perchlorate adopts high-precision particle control and special surface treatment methods to make the particle size more uniform and the surface smoother, thereby significantly improving the fluidity and stability of the product. This improvement makes the use of quicksand potassium perchlorate in rocket propellants, fireworks and explosives safer and more reliable, while also reducing production and storage costs.

[0003] The utility model patent with application number: CN202222777382.1 and publication number: CN218210629U (hereinafter referred to as "prior art 1") discloses a crystalline potassium perchlorate production system, which relates to the field of potassium perchlorate production equipment. The present invention includes a hot air mixing section, a cyclone separation section, a vibrating screen separation section and a packaging section; the hot air discharge end of the material in the hot air mixing section is connected to the cyclone separation section, and the top air discharge end of the cyclone separation section is connected to the bag dust collector; the bottom discharge end of the cyclone separation section is connected to the vibrating screen separation section, the lower discharge end of the vibrating screen separation section is connected to the packaging section, the upper discharge end of the vibrating screen separation section is connected to the feed end of the mill, and the discharge end of the mill is connected to the packaging section;

[0004] The specification of prior art 1 discloses a crystalline potassium perchlorate production system. When in use, the semi-finished potassium perchlorate material is allowed to enter the hot air mixing section. After being dried by the hot air, the material enters the cyclone separation section along with the hot air, so that the material entering the cyclone separation section is blown in by the hot air, thereby increasing the contact time between the material and the hot air and improving the drying efficiency. However, in actual applications, it is impossible to prevent potassium perchlorate from caking during storage by drying and heating. Potassium perchlorate has the characteristic of easy caking during storage. The caking of potassium perchlorate is due to the combined effect of the particle's own factors and external factors, which causes dissolution and recrystallization on the particle surface, thereby forming a crystal bridge at the contact point between the crystal grains, so that the crystal grains are bonded together, lose fluidity, and gradually form a hard block. The caking of potassium perchlorate seriously affects its sales and use. Summary of the invention

[0005] The invention provides a quicksand type potassium perchlorate production device, aiming to solve the problem that potassium perchlorate agglomerates when producing potassium perchlorate in the potassium perchlorate production device in the prior art.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0013] Furthermore, a hinged portion is provided on the cover body, and the rod body is hinged to the cover body via the hinged portion.

[0014] Furthermore, a stepped groove is provided at the opening position of the barrel, and a sealing gasket is provided below the cover body. When the cover body is closed, the sealing gasket contacts the stepped groove to form a seal.

[0015] Furthermore, a workbench is provided below the barrel, and the screening trough and the motor are both installed on the workbench.

[0016] Furthermore, the discharge port is connected to the feed port on the side wall of the screening trough through a discharge channel, the discharge channel is inclined, and a gate is provided on the discharge port.

[0017] Furthermore, a plurality of brackets are arranged on the screening trough, and each of the brackets is provided with a vibration motor.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The invention mainly comprises a centrifuge, a centrifugal high-level tank, a mixing device, a screening device and a soaking tank. In actual use, a worker first adds 65% volume of soft water into the soaking tank, then adds SDS, TX10 and KF865 in a ratio of 1:1:1, and heats the soaking tank to dissolve the blocky potassium perchlorate in the soaking tank to form potassium perchlorate wet crystals; then the potassium perchlorate wet crystals are poured into a barrel, and a nano-scale hydrophobic powder anti-caking agent is added into the barrel, and then a stirring mechanism is driven to fully stir and mix the potassium perchlorate wet crystals and the nano-scale hydrophobic powder anti-caking agent in the barrel, and the stirred potassium perchlorate wet crystals are discharged through a discharge port.

The liquid formed after centrifugation flows back to the soaking tank, and the solids are collected. Finally, the collected solids are dried to form quicksand potassium perchlorate. The advantage of this arrangement is that the hydrophilic groups are adsorbed on the surface of potassium perchlorate particles, and the hydrophobic groups face the gas phase, making the particle surface hydrophobic, hindering the entry of atmospheric moisture, and inhibiting the deliquescence of the granular product. The adsorbed surfactant can also reduce the capillary adsorption force of the particles to the solution, improve the crystallization habits of the solid particles, greatly reduce the interfacial energy of the particle crystals, and inhibit nucleation, thereby having a good anti-caking effect on potassium perchlorate particles.

DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with embodiments, which are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in the field 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 the quicksand type potassium perchlorate; wherein the device includes a centrifuge, a centrifugal high-level tank, a mixing device, a screening device and a soaking tank, and 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 feed port of the barrel 101, and the discharge port 104 is opened at the bottom of the barrel 101, and the stirring mechanism 102 is used to mix a plurality of materials inside the barrel 101;

[0028] The screening device includes: a screening trough 105, a lower material bin 106, a filter screen 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, and the discharge port 104 is used to open or close; the lower material bin 106 is installed at the lower opening of the screening trough 105, the filter screen 107 is installed inside the screening trough 105, the height of the discharge port 104 is higher than the filter screen 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 bin 106, the outlet end of the soaking tank is connected to the centrifugal high-level tank, the centrifugal high-level tank is used to store the material in the soaking tank, and 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 present invention mainly comprises a centrifuge, a centrifugal high-level tank, a mixing device, a screening device and a soaking tank. In actual use, a worker first adds 65% 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 in the soaking tank to form potassium perchlorate wet crystals; then the potassium perchlorate wet crystals are poured into a barrel 101, and a nano-scale hydrophobic powder anti-caking agent is added into the barrel 101, and then a stirring mechanism 102 is driven to fully stir and mix the potassium perchlorate wet crystals and the nano-scale hydrophobic powder anti-caking agent in the barrel 101, and the stirred potassium perchlorate wet crystals are discharged through a discharge port 104. The potassium perchlorate wet crystals are then stirred 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 the centrifugation flows back into the soaking tank, and the solids are collected. Finally, the collected solids are dried to form quicksand potassium perchlorate. The potassium perchlorate wet crystals and the nano-hydrophobic powder anti-caking agent are fully stirred by the stirring mechanism, so that the potassium perchlorate wet crystals are less likely to agglomerate, and the lumpy potassium perchlorate wet crystals can be filtered through the screening trough 105. In addition, 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, so as to further improve 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] In 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 be used to 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 cylinder 114 to extend. At this time, the rod part of the cylinder 114 slides out from the cylinder body part of the cylinder 114, and then the rod part of the cylinder 114 extends out to support the cover body 113, so that the cover body 113 rotates around the barrel 101, and then the barrel 101 is opened; conversely, when it is necessary to close the cover body 113, it is necessary to control the originally extended cylinder 114 to contract. After the cylinder 114 contracts, the cover body 113 is pulled closed, thereby completing the closing of the barrel 101.

[0038] In some embodiments, a hinge portion 115 is disposed 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 115 can make the rotation between the cover body 113 and the barrel 101 smoother.

[0040] In some embodiments, a stepped groove 116 is disposed at the opening of the barrel 101 , and a sealing gasket is disposed 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] In actual use, when the cover body 113 is closed, the sealing gasket below 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 disposed 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 setting 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] In actual use, it is necessary to first slightly open the gate to allow the material inside the barrel 101 to fall 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 disposed 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 potassium perchlorate wet crystals with a larger volume are re-introduced into the soaking tank for dissolution.
