For example, in industrial production and food processing, calcium hydroxide is used as an acid antacid, dehydrating agent, rust remover, etc.

[0003] In order to ensure that quicklime can be fully digested, a three-stage calcium hydroxide digester is usually used in its production. Through multi-stage stirring and temperature control, the materials and water are fully mixed to promote the digestion reaction of quicklime.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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.

[0025] Specific examples are given below.

[0026] like Figure 1-4As shown, a three-stage calcium hydroxide digester that meets the requirement of full digestion includes a digester body 1; a driving member 11 is installed in the middle of the digester body 1; a stirring rod 12 is fixedly connected to the output end of the driving member 11; two groups of frame plates 13 are fixedly connected to the middle of the stirring rod 12; a filter screen 14 is fixedly connected to the inner wall of the frame plate 13; a spring rod 15 is fixedly connected to the top of the frame plate 13; a connecting rod 16 is fixedly connected to the output end of the spring rod 15; a scraper 17 is fixedly connected to the inner wall of the connecting rod 16, and the middle part of the scraper 17 is in contact with the filter screen 14; when working, the staff needs to install the digester body 1 in the working area, and then open the flip cover on the top of the digester body 1, and pour part of the material and water into the digester body 1, and after starting the switch of the driving member 11, the stirring rod 12 stirs and digests the material, and by arranging two groups of frame plates 13 in the middle of the stirring rod 12, the driving member 11 will synchronously drive the two groups of frame plates when working. The plate 13 rotates, and the filter screen 14 pushes and vibrates the agglomerated materials inside the digester body 1 to disperse them, and then discharges them through the small holes in the middle thereof. When the driving member 11 rotates, under the action of centrifugal force, the output end of the spring rod 15 will be stretched, and the connecting rod 16 will slide synchronously, and the scraper 17 will scrape and clean the middle part of the reinforcement rod 4. At the same time, when the driving member 11 stops rotating, under the elastic force of the spring rod 15, the connecting rod 16 will retract and reset, and scrape the middle part of the filter screen 14 again. This step is combined with the filter screen 14 to reduce the mixing of some agglomerated materials inside the digester body 1, so that the problem of uneven mixing and digestion occurs when the subsequent driving member 11 rotates and stirs, thereby improving the dispersion and fluidity of the materials inside the digester body 1. The scraper 17 that can be slidably arranged can reduce the problem of clogging of the holes in the middle of the filter screen 14 after long-term use.

[0027] like Figure 2 and 5As shown, a reciprocating screw 2 is fixedly connected to the bottom of the output end of the driving member 11; two groups of support members 21 are fixedly connected to the inner wall of the digester body 1; a slider 22 is slidably connected to the middle of the support member 21, and the slider 22 and the reciprocating screw 2 are threadedly connected; two groups of rotating plates 23 are connected to the torsion spring in the middle of the reciprocating screw 2; a cloth strip 24 is fixedly connected to the end of the rotating plate 23, and the cloth strip 24 is arranged on the bottom wall of the digester body 1; when working, the reciprocating screw 2 is arranged at the bottom of the output end of the driving member 11, so that the driving member 11 can synchronously drive the reciprocating screw 2 to rotate when it is working, and when the reciprocating screw 2 is rotating, and under the action of the support member 21 limiting the position, the slider 22 can only slide up and down, and the arranged cloth strip 24 can move the sediment while the reciprocating screw 2 rotates. The agglomerated materials on the bottom wall of the digester body 1 are pushed up and broken up by the filter screen 14 again. During the upward sliding process of the slider 22, the top thereof will lift up the two sets of rotating plates 23 until the cloth strip 24 is separated from the bottom of the digester body 1. At the same time, after the slider 22 and the rotating plates 23 are separated, the cloth strip 24 and the rotating plates 23 can be reset to their positions under the action of the torsion spring. This step, in conjunction with the set cloth strip 24, can reduce the problem that some materials are precipitated at the bottom of the digester body 1, so that the driving member 11 needs to rotate for a long time to mix the materials. At the same time, in conjunction with the set slider 22, the flexibility of the cloth strip 24 during work can be improved, so that the cloth strip 24 can push the materials at the bottom of the digester body 1 in a partitioning manner, thereby improving the service life of the cloth strip 24.

[0028] like Figure 5 As shown, a groove 3 is provided at the bottom of the rotating plate 23; an elastic rope 31 is fixedly connected to the inner wall of the groove 3; an impact piece 32 is fixedly connected to the end of the elastic rope 31, and the impact piece 32 is slidably arranged on the inner wall of the groove 3; during operation, the groove 3 is provided at the bottom of the rotating plate 23, so that when the driving member 11 is not rotating, the impact piece 32 will be suspended in the middle of the groove 3 under the action of the elastic rope 31, and when the driving member 11 is rotating, under the action of centrifugal force, the impact piece 32 will hit the inner wall of the groove 3 and generate vibration force, and then the elastically set elastic rope 31 can be reset. This step cooperates with the force generated by the impact of the impact piece 32 to improve the cleanliness of the rotating plate 23 and the middle of the cloth strip 24, and reduce the accumulation of some agglomerated materials adhering to its surface, which makes it troublesome for subsequent staff to clean up.

[0029] like Figure 3As shown, the output end of the spring rod 15 is fixedly connected to a reinforcing rod 4; the end of the reinforcing rod 4 is fixedly connected to a counterweight ball 41; during operation, by arranging the reinforcing rod 4 at the end of the spring rod 15, the spring rod 15 can be rotated and the middle part of the spring rod 15 can be stretched faster under the action of the gravity of the counterweight ball 41. This step, combined with the counterweight ball 41, can improve the stability of the middle part of the spring rod 15 during movement, and reduce the problem that after the output end of the spring rod 15 reciprocates for a long time, a large amount of impurities are accumulated at its sliding part, making it difficult for its output end to be thrown out later. The reinforcing rod 4 can reinforce the working position of the counterweight ball 41.

[0030] like Figure 5 As shown, a reinforcing sheet 5 is fixedly connected to the top of the cloth strip 24; during operation, by arranging the reinforcing sheet 5 in the middle of the cloth strip 24, and under the action of the downward gravity of the reinforcing sheet 5, the cloth strip 24 is in deep contact with the bottom of the digester body 1. This step cooperates with the arranged reinforcing sheet 5 to improve the accuracy of the cloth strip 24 in lifting impurities at the bottom of the digester body 1, and further improves the speed of mixing the materials inside the digester body 1.

[0031] like Figure 4 As shown, the end of the spring rod 15 is fixedly connected with a seal 6, and the inside of the seal 6 is in contact with the output end of the spring rod 15; when working, by arranging the seal 6 at the end of the spring rod 15, the seal 6 will seal the sliding area of ​​its output end. This step can further reduce the accumulation and adhesion of impurities, improve the cycle of the spring rod 15 during use, and reduce the problem of frequent maintenance or replacement required by subsequent staff.

[0032] like Figure 5 As shown, a gasket 7 is fixedly connected to the top of the slider 22, and the gasket 7 is arranged at the bottom of the two groups of rotating plates 23; when working, by arranging the gasket 7 on the top of the slider 22, when the slider 22 is close to the position of the two groups of rotating plates 23, the gasket 7 will first make deep contact with the slider 22, and this step cooperates with the gasket 7 to increase the friction force generated when the slider 22 contacts the rotating plate 23, and at the same time, the bottom of the rotating plate 23 can be protected to reduce the wear on its surface.

[0033] Working principle: by installing the digester body 1 in the working area, the flap on the top of the digester body 1 can be opened, and part of the material and water can be poured into the digester body 1, and after the switch of the driving member 11 is turned on, the stirring rod 12 is used to stir and digest the material. By arranging two groups of frame plates 13 in the middle of the stirring rod 12, the driving member 11 can synchronously drive the two groups of frame plates 13 to rotate when working, and the filter screen 14 can push and vibrate the agglomerated material inside the digester body 1, and then discharge it through the small hole in the middle. When the driving member 11 rotates, under the action of centrifugal force, the output end of the spring rod 15 will be stretched, and the connecting rod 16 will slide synchronously, and the scraper 17 will scrape and clean the middle part of the reinforcement rod 4. At the same time, when the driving member 11 stops rotating, under the elastic force of the spring rod 15, the connecting rod 16 will retract and reset, and scrape the middle part of the filter screen 14 again. By arranging a reciprocating screw 2 at the bottom of the output end of the driving member 11, the driving member 11 will synchronously drive the reciprocating screw 2 to rotate when it is working, and when the reciprocating screw 2 rotates, and under the limiting action of the support member 21, the slider 22 can only slide up and down, and the cloth strip 24 can push the agglomerated materials deposited on the bottom wall of the digester body 1 while the reciprocating screw 2 rotates. The cloth strip 24 and the rotating plate 23 are lifted up and the filter screen 14 is used to break up the cloth strip 24 again. During the upward sliding process of the slider 22, the top of the slider 22 lifts up the two sets of rotating plates 23 until the cloth strip 24 is separated from the bottom of the digester body 1. At the same time, after the slider 22 and the rotating plate 23 are separated, the cloth strip 24 and the rotating plate 23 can be reset under the action of the torsion spring. By providing a groove 3 at the bottom of the rotating plate 23, when the driving member 11 is not rotating, the impact member 32 is suspended in the middle of the groove 3 under the action of the elastic rope 31. At the same time, when the driving member 11 is rotating, the impact member 32 will hit the inner wall of the groove 3 under the action of the centrifugal force and generate vibration force, and then the elastic spring can be used to release the cloth strip 24 and the rotating plate 23. The elastic rope 31 is arranged to reset the spring rod 15. A reinforcing rod 4 is arranged at the end of the spring rod 15, so that when the spring rod 15 rotates, and under the action of the gravity of the counterweight ball 41, the speed of stretching the middle part of the spring rod 15 can be accelerated. A reinforcing sheet 5 is arranged in the middle of the cloth strip 24, and under the action of the downward gravity of the reinforcing sheet 5, the cloth strip 24 is deeply contacted with the bottom of the digester body 1. A sealing member 6 is arranged at the end of the spring rod 15, so that the sealing member 6 will seal the sliding area of ​​its output end. A gasket 7 is arranged on the top of the slider 22, so that when the slider 22 is close to the position of the two sets of rotating plates 23, the gasket 7 will first be deeply contacted with the slider 22.
