The outlet of the feeding device is connected to the inlet of the continuous fluidized bed dryer, and the outlet of the continuous fluidized bed dryer is connected to the inlet of the vibrating screen. The bed dryer has three temperature control zones connected by a material transfer mechanism; each temperature control zone has at least one hot air inlet; the hot air inlet is connected to a blower via a preheater; the vibrating screen includes a screen frame, a screen mesh inside the screen frame, at least one screen mesh support frame on the screen frame, and each screen mesh support frame includes a vertical support plate fixed to the screen frame; a horizontal support plate is provided at the bottom of the vertical support plate; the screen mesh is installed between the horizontal support plates. However, the following technical problems exist:

[0003] When hydrated betaine is dried in a continuous fluidized bed dryer, the betaine lumps in the continuous fluidized bed dryer are conveyed to a vibrating screen. However, the anhydrous betaine lumps in the vibrating screen cannot be broken up. Excessive betaine lumps tend to accumulate in the vibrating screen, making it difficult for betaine to be conveyed. Utility Model Content

[0004] To address the problem mentioned in the background art that betaine lumps easily accumulate in the vibrating screen, this utility model provides the following technical solution:

[0005] A continuous drying apparatus for anhydrous betaine, comprising a drying chamber;

[0006] The drying oven is equipped with a conveyor box for transporting betaine.

[0007] The conveyor box includes spiral conveyor blades for conveying aqueous betaine, and a crushing roller for crushing anhydrous betaine is installed at the lower end of the spiral conveyor blades.

[0008] The drying chamber is equipped with a limiting structure for limiting the position of the conveyor box. The lower end of the limiting structure is equipped with a transmission block for controlling the vibration of the conveyor box in conjunction with the limiting structure. One end of the transmission block is provided with a toothed groove. The drying chamber is equipped with a bevel gear for controlling the rotation of the transmission block in conjunction with the toothed groove.

[0009] Furthermore, a top cover is installed at the upper end of the drying box, and a feed inlet is installed at the upper end of the top cover.

[0010] Furthermore, the inner wall of the drying box is equipped with multiple heating rods for heating the inner cavity of the drying box, the lower end of the drying box is equipped with a discharge port, the upper inner wall of the drying box is equipped with multiple limiting blocks for limiting the limiting structure, the inner wall of the drying box is equipped with a support ring for supporting the transmission block, and the upper end of the support ring is equipped with a pressure ring for limiting the transmission block.

[0011] Furthermore, the limiting structure includes a limiting tube, the middle of which has multiple through slots to facilitate heat radiation, a fixing ring installed at the upper end of the limiting tube, the outer wall of the fixing ring having multiple sliding grooves for cooperating with the limiting block to limit the limiting structure, and an annular corrugated block installed at the bottom of the fixing ring.

[0012] Furthermore, the outer wall of the drying oven is equipped with a support platform for supporting the drying oven, and a storage battery is installed at the upper end of the support platform.

[0013] Furthermore, an annular corrugated block two is installed at the upper end of the transmission block for engaging with the annular corrugated block one, a plurality of ball bearings are installed at the bottom of the transmission block, and a motor one for controlling the rotation of the bevel gear is installed at one end of the bevel gear.

[0014] Furthermore, the conveying box includes a box body, and spiral conveying blades are installed in the inner cavity of the box body. A limiting tube is sleeved on the upper end of the box body, and the bottom wall of the box body is provided with multiple discharge holes for anhydrous betaine to fall.

[0015] Furthermore, a reduction motor for controlling the rotation of the spiral conveyor blade is installed at the lower end of the spiral conveyor blade, a connecting frame for limiting the position of the crushing roller is installed at the lower end of the spiral conveyor blade, and multiple crushing blades are installed in the middle of the crushing roller, and the crushing blades cooperate with the inner cavity bottom wall of the box to crush anhydrous betaine.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] During continuous drying of hydrated betaine, the heating rod heats the inner cavity of the drying chamber, and the inner cavity of the chamber is heated simultaneously. The hydrated betaine is continuously fed into the chamber through the feed inlet. The geared motor controls the spiral conveyor blades to convey the hydrated betaine downwards. The hydrated betaine is converted into anhydrous betaine through thermal radiation. The bevel gear and tooth groove synchronously drive the transmission block to rotate. With the cooperation of the second and first annular corrugated blocks, the limiting structure causes the conveyor box to vibrate. When the conveyor box vibrates, it can accelerate the drying rate of the hydrated betaine. Moreover, when the conveyor box vibrates, it can prevent the accumulation of anhydrous betaine on the bottom wall of the inner cavity of the chamber. It helps the crushing roller to crush the blocky anhydrous betaine on the bottom wall of the inner cavity of the chamber, so that the powdery anhydrous betaine can be conveyed downwards through the discharge hole and discharge port. It can be seen that this new type of device can continuously crush blocky anhydrous betaine during the continuous drying of hydrated betaine, so that the anhydrous betaine can be conveyed downwards through the discharge hole.

[0026] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0027] Please see Figures 1-5 This utility model provides a continuous drying device for anhydrous betaine, including a drying box 100. A top cover 110 is installed on the upper end of the drying box 100, and a feed inlet 111 is installed on the upper end of the top cover 110. A conveyor box 200 for conveying betaine is installed inside the drying box 100. When continuous drying of betaine is required, the hydrated betaine can be conveyed to the upper end of the feed inlet 111 by a conveyor belt of existing technology. The hydrated betaine falls into the feed inlet 111 and falls into the conveyor box 200 in the middle of the drying box 100. It is conveyed downward through the conveyor box 200. An air outlet is opened on the top cover 110 to facilitate the dissipation of water vapor to the outside of the drying box 100.

[0028] The drying oven 100 has a limiting structure 120 installed inside to limit the movement of the conveyor box 200. The limiting structure 120 is sleeved on the upper end of the conveyor box 200. The lower end of the limiting structure 120 is equipped with a transmission block 140 for controlling the vibration of the conveyor box 200 in conjunction with the limiting structure 120. One end of the transmission block 140 has a toothed groove 143. The drying oven 100 has a bevel gear 150 installed inside to control the rotation of the transmission block 140 in conjunction with the toothed groove 143. One end of the bevel gear 150 is equipped with a control mechanism for the bevel gear. The motor 151 rotates, and the tooth block and tooth groove 143 on the bevel gear 150 mesh with each other. When the motor 151 controls the bevel gear 150 to rotate, the bevel gear 150 and the tooth groove 143 synchronously drive the transmission block 140 to rotate. When the transmission block 140 rotates, it works with the limiting structure 120 to drive the conveyor box 200 to vibrate. This allows the raw materials in the conveyor box 200 to be transported more efficiently, thus avoiding the situation where the betaine in the middle of the betaine pile is difficult to dry.

[0029] The inner wall of the drying oven 100 is equipped with multiple heating rods 101 for heating the inner cavity of the drying oven 100. The heat generated by the multiple heating rods 101 is transferred to the interior of the conveyor box 200 by thermal radiation, thereby achieving the purpose of drying the water-containing betaine inside the conveyor box 200.

[0030] A discharge port 102 is fixedly installed at the lower end of the drying chamber 100. The pulverized anhydrous betaine falls through the discharge port 102. A conveyor belt, as used in the prior art, can be installed at the bottom of the discharge port 102 to facilitate the transport of the dried anhydrous betaine to the next stage. Multiple limiting blocks 103 for limiting the limiting structure 120 are fixedly installed on the upper inner wall of the drying chamber 100. A support ring 104 for supporting the transmission block 140 is installed on the inner wall of the drying chamber 100. A pressure ring 105 for limiting the transmission block 140 is installed at the upper end of the support ring 104, and the pressure ring 105 has an L-shaped cross-section, according to the attached drawings. Figure 3 It can be seen that when the transmission block 140 is placed on the upper end of the support ring 104, the pressure ring 105 is placed on the support ring 104, so that the pressure ring 105 limits the transmission block 140, and the transmission block 140 can only rotate and cannot move up and down.

[0031] The limiting structure 120 includes a limiting tube 121. Multiple through slots 122 are provided in the middle of the limiting tube 121 to facilitate heat radiation. These through slots 122 facilitate heat transfer into the conveying box 200. A fixing ring 123 is fixedly installed at the upper end of the limiting tube 121. Multiple sliding grooves 124 are provided on the outer wall of the fixing ring 123 to cooperate with the limiting block 103 in limiting the limiting structure 120. The limiting block 103 slides within the grooves 124, allowing the limiting structure 120 to move only up and down. An annular corrugated block 125 is fixedly installed at the bottom of the fixing ring 123. The lower end of the annular corrugated block 125 has multiple protrusions and grooves. The upper end of the transmission block 140 is equipped with an annular corrugated block 141 for engaging with the annular corrugated block 125. The annular corrugated block 141 and the annular corrugated block 125 have the same structure. When the protrusion of the annular corrugated block 141 and the groove of the annular corrugated block 125 come into contact, the fixing ring 123 and the transmission block 140 move closer. When the protrusion of the annular corrugated block 141 and the protrusion of the annular corrugated block 125 come into contact, the fixing ring 123 and the transmission block 140 move further apart. This ensures that when the limiting structure 120 rotates, the protrusion of the annular corrugated block 141 continuously contacts the protrusion and groove of the annular corrugated block 125, thereby achieving the effect of vibrating the conveyor box 200.

[0032] A support platform 130 for supporting the drying oven 100 is fixedly installed on the outer wall of the drying oven 100, and a storage battery 131 is installed on the upper end of the support platform 130. A plurality of ball bearings 142 are installed on the bottom of the transmission block 140, and the arrangement of the plurality of ball bearings 142 facilitates the rotation of the transmission block 140 on the support ring 104.

[0033] The conveying box 200 includes a spiral conveying blade 220 for conveying hydrated betaine. The conveying box 200 includes a box body 210, which is fixedly installed on the upper end of the fixing ring 123 by bolts, so that when the limiting structure 120 moves up and down, the conveying box 200 moves up and down synchronously. The spiral conveying blade 220 is installed in the inner cavity of the box body 210, and the limiting tube 121 is sleeved on the upper end of the box body 210. The bottom wall of the box body 210 has multiple discharge holes 211 for anhydrous betaine to fall. The spiral conveying blade 220 conveys the hydrated betaine downward. When the hydrated betaine is conveyed downward, the heating rod 101 continuously heats it, causing the water in the hydrated betaine to evaporate. When the hydrated betaine is conveyed to the bottom of the box body 210, it becomes anhydrous betaine. The powdered anhydrous betaine falls through the discharge holes 211.

[0034] A geared motor 221 is installed at the lower end of the spiral conveying blade 220 to control the rotation of the spiral conveying blade 220. The geared motor 221 controls the rotation of the middle part of the spiral conveying blade 220, thereby driving the spiral conveying blade 220 to convey betaine. A connecting frame 222 for limiting the crushing roller 223 is fixedly installed at the lower end of the spiral conveyor blade 220. A crushing roller 223 for crushing anhydrous betaine is installed at the lower end of the spiral conveyor blade 220. Multiple crushing blades 224 are fixedly installed in the middle of the crushing roller 223. The crushing blades 224 cooperate with the bottom wall of the inner cavity of the box 210 to crush the anhydrous betaine. When the blocky anhydrous betaine cannot pass through the discharge hole 211, the spiral conveyor blade 220 rotates to convey the betaine. At the same time, the spiral conveyor blade 220 drives the connecting frame 222 to rotate at the bottom of the inner cavity of the box 210, so that the crushing roller 223 crushes the blocky anhydrous betaine at the bottom of the inner cavity of the box 210, so as to crush the blocky anhydrous betaine and make the powdery anhydrous betaine fall through the discharge hole 211.

[0035] During continuous drying of hydrated betaine, heating rod 101 heats the inner cavity of drying chamber 100, and the inner cavity of chamber 210 is simultaneously heated. Hydrated betaine is continuously fed into chamber 210 through feed inlet 111. Gear motor 221 controls spiral conveyor blades 220 to convey the hydrated betaine downwards. The hydrated betaine is converted into anhydrous betaine through thermal radiation. Bevel gear 150, in conjunction with tooth groove 143, synchronously drives transmission block 140 to rotate. (The text abruptly ends here, likely due to an incomplete sentence or missing information.) The cooperation of 141 and the annular corrugated block 125 causes the limiting structure 120 to drive the conveyor box 200 to vibrate. When the conveyor box 200 vibrates, it can accelerate the drying rate of the hydrated betaine. When the conveyor box 200 vibrates, it can prevent the accumulation of anhydrous betaine on the bottom wall of the inner cavity of the box 210. This helps the crushing roller 223 to crush the blocky anhydrous betaine on the bottom wall of the inner cavity of the box 210, so that the powdered anhydrous betaine can be conveyed downward through the discharge hole 211 and the discharge port 102.

[0036] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
