Description

Technical Field

[0001] The utility model belongs to the technical field of reaction kettle cleaning, and in particular relates to a cleaning device for a vertical silver sulfate reaction kettle. Background Art

[0002] Silver sulfate is a sulfate with the chemical formula Ag2SO4. It is soluble in nitric acid, ammonia water and concentrated sulfuric acid, insoluble in ethanol, slightly soluble in water, and increases with the decrease of the pH of the solution environment. When the hydrogen ion concentration is large enough, there can be obvious dissolution. It is used as an analytical reagent and a catalyst when determining the chemical oxygen demand in water. For the preparation of silver sulfate, silver nitrate is dissolved in hot water and then dissolved in an aqueous solution of ammonium sulfate. After filtering, heat and add this hot solution to the hot silver nitrate solution. After cooling, filter out the silver sulfate crystals by suction, then wash with water and dry.

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0051] In the process of preparing silver sulfate, a corresponding reactor is used for preparation. After the preparation of silver sulfate is completed, the reactor needs to be cleaned. In the existing reactor cleaning device, if stubborn residues are encountered during the cleaning process of the inner wall of the reactor, it is necessary to increase the output power of the water pump to flush the inner wall of the reactor, and increase the pressure of the cleaning part on the inner wall of the reactor to scrape off the stubborn residues, which is complicated to operate.

[0052] To solve the above technical problems, in at least one embodiment, a cleaning device for a vertical silver sulfate reactor is provided, comprising: a rotating shaft 4, which is arranged inside the reactor 1, and the interior of the rotating shaft 4 is hollow and provided with cleaning water; wherein a driving mechanism is arranged at the top of the rotating shaft 4 to drive the rotating shaft 4 to rotate when the driving mechanism is started; a cleaning mechanism, which is arranged on the outer wall of the hollow rotating shaft 4, and is suitable for spraying the cleaning water toward the inner wall of the reactor 1 through the water outlet end of the cleaning mechanism when the rotating shaft 4 rotates; and an auxiliary mechanism, which is slidably connected with the cleaning mechanism, and is suitable for sliding relative to the cleaning mechanism when the rotation speed of the rotating shaft 4 increases to press the water outlet end of the cleaning mechanism, thereby increasing the flow rate of the cleaning water and cleaning the inner wall of the reactor 1.

[0053] A driving mechanism is provided to drive the rotating shaft 4 to rotate, and the top end of the rotating shaft 4 is connected to the bearing of the top inner wall of the reactor 1, so as to drive the auxiliary mechanism to scrape the residue on the inner wall of the reactor 1, and utilize the cleaning mechanism to spray water toward the inner wall of the reactor 1 for auxiliary cleaning. By increasing the output power of the driving mechanism, that is, increasing the rotation speed of the rotating shaft 4, the auxiliary mechanism and the cleaning mechanism slide relative to each other, and while increasing the pressure applied by the auxiliary mechanism to the inner wall of the reactor 1, the area of ​​the water outlet end of the cleaning mechanism is reduced, and the flow rate of the water outlet end is increased, that is, the impact force of the cleaning water on the inner wall of the reactor 1 is simultaneously increased, thereby cleaning the residue adhered to the inner wall of the reactor 1.

[0054] In some embodiments, for the reactor 1 for preparing silver persulfate, a water inlet pipe 2 is used, one end of which is connected to a water tank, and a pump can be used to pump cleaning water into a rotating shaft 4 provided inside the reactor 1. A plurality of cleaning cylinders 40 are fixed on the rotating shaft 4, and a cleaning pipe 400 is fixed inside each cleaning cylinder 40, and a water outlet end thereof faces the inner wall of the reactor 1. The cleaning water inside the rotating shaft 4 passes through the water inlet end of the cleaning pipe 400, and is sprayed out from the water outlet end thereof to clean the inner wall of the reactor;

[0055] At the same time, a slide groove 404 is opened on the inner wall of the cleaning cylinder 40, and the auxiliary rod 41 is slidably connected to the slide groove 404 by relying on a slider 410 fixed on its outer wall, so that the auxiliary rod 41 can slide on the inner wall of the cleaning cylinder 40, and a cleaning part 42 is fixed at one end of the auxiliary rod 41 close to the inner wall of the reactor 1. The cleaning part 42 is made of flexible material, and the outer wall of the cleaning part 42 fits with the inner wall of the reactor 1, so that the residue on the inner wall of the reactor 1 can be wiped and scraped off during the rotation of the rotating shaft 4, and the inner wall of the reactor 1 can be cleaned in cooperation with the cleaning water.

[0056] In some embodiments, for stubborn residues on the inner wall of the reactor 1, it is only necessary to increase the output power of the driving motor 3, and its output end drives the driving gear to rotate rapidly, thereby driving the driven gear 31 to rotate rapidly, and the driven gear 31 is sleeved on the outer wall of the rotating shaft 4, thereby increasing the rotation speed of the rotating shaft 4;

[0057] When the rotation speed of the rotating shaft 4 increases, the auxiliary rod 41 drives the cleaning member 42 to slide on the inner wall of the cleaning cylinder 40 toward the inner wall of the reactor 1, so that the cleaning member 42 fits more closely with the inner wall of the reactor 1, and then wipes off the stubborn residue during the rotation of the cleaning member 42. While the auxiliary rod 41 slides, it drives the active member 44 fixed on its outer wall to move, and the active member 44 fits with the driven member 43, thereby pushing the driven member 43 and the extrusion plate 401 to slide upward on the guide rod 403, and by reducing the distance between the extrusion plate 401 and the arc-shaped top plate 402, the water outlet end of the cleaning pipe 400 is squeezed, and the area of ​​the water outlet end is reduced to increase the water flow rate at the water outlet end, thereby increasing the impact force of the cleaning water on the inner wall of the reactor 1, and washing away the stubborn residue scraped off by the cleaning member 42. After cleaning is completed, the reset spring 45 is recovered to drive the auxiliary rod 41 to reset.

[0058] In some embodiments, during the preparation of silver sulfate, the prepared material is introduced into the interior of the reactor 1 from the top feed port of the reactor 1, the cleaning part 42 is disassembled, and a sealing sleeve is sleeved on the end of the auxiliary rod 41, and then the auxiliary rod 41 is pushed deep into the interior of the cleaning cylinder 40, and the reset spring 45 is compressed. After the inner wall of the sealing sleeve is fitted with the outer wall of the end of the cleaning cylinder 40, the sealing sleeve is fixed on the cleaning cylinder 40. At this time, when the drive motor 3 is started, the cleaning cylinder 40 is used to stir the liquid and silver sulfate in the reactor 1.

[0059] To summarize, a driving mechanism is provided, and the driving mechanism is used to drive the rotating shaft to rotate, so as to drive the auxiliary mechanism to scrape the residue on the inner wall of the reactor, and the cleaning mechanism is used to spray water toward the inner wall of the reactor to assist in cleaning. By increasing the output power of the driving mechanism, that is, increasing the rotation speed of the rotating shaft, the auxiliary mechanism and the cleaning mechanism slide relative to each other, and while increasing the pressure applied by the auxiliary mechanism to the inner wall of the reactor, the area of ​​the water outlet end of the cleaning mechanism is reduced, and the flow rate of the water outlet end is increased, that is, the impact force of the cleaning water on the inner wall of the reactor is simultaneously increased, thereby cleaning the residues adhered to the inner wall of the reactor.
