[0026] First embodiment

[0027] See Figure 1-3 This embodiment provides a heating, stirring and dehumidifying device for dialysis powder processing, which includes a sandwich heating and stirring barrel 110, a sealing cover 120 arranged on the upper part of the sandwich heating and stirring barrel 110, a stirring component 130 and a dehumidifying component 140.

[0028] Specifically, a coiled heating water pipe is installed within the interlayer of the interlayer heating mixing drum 110. The return pipe 111 of the heating water pipe is connected to a constant temperature drum 112. The water outlet of the constant temperature drum 112 is connected in sequence to a circulation pump 113, a water inlet pipe 114, and the heating water pipe, forming a heating cycle. The circulating pump 113 circulates hot water through the mixing drum interlayer, and the temperature-controlled constant temperature drum 112 maintains the water at 50±1°C, avoiding the yellowing caused by local overheating caused by the use of electric heating plates. At the same time, the traditional vertical drying mixer method of using a fan to blow hot air into the interlayer to increase the mixing drum temperature is changed to meet the requirements of a clean workshop environment.

[0029] A feed pipe 121 is provided on the sealing cover 120 of the interlayer heating and stirring barrel 110 , and a discharge pipe 115 is provided at the bottom of the interlayer heating and stirring barrel 110 . Both the feed pipe 121 and the discharge pipe 115 are controlled by electromagnetic valves to precisely control feeding and discharging.

[0030] In order to address the problem that some dialysis powder is sucked away by the fan during the traditional dialysis powder dehumidification process, the present embodiment has a redesigned dehumidification component 140. The dehumidification component 140 includes a dehumidification pipe 141, a multi-layer corrugated mesh plate 142, and a vacuum pump 143. When the vacuum pump 143 extracts internal moisture, the dialysis powder is blocked at the position of the multi-layer corrugated mesh plate 142, thereby overcoming the original defect.

[0031] Specifically, the dehumidification tube 141 is arranged in an oblique upward state and is detachably connected to the sealing cover 120, and the dehumidification tube 141 and the internal stirring chamber of the interlayer heating and stirring barrel 110 are connected, so that the humid air flow can be smoothly extracted; the inner wall of the dehumidification tube 141 is provided with a hanging groove 1411 for assembling a multi-layer corrugated mesh plate 142; the outer ring sleeve of the dehumidification tube 141 is provided with an annular vibrating member 144 for intermittent start-up to shake the agglomerated dialysis powder into the interlayer heating and stirring barrel 110, and the annular vibrating member 144 can be purchased from an ordinary annular vibrating member online; the end of the corrugated mesh plate 142 is provided with a hook 1421 that cooperates with the hanging groove 1411, and the hanging groove 1411 and the hook 1421 are connected by a flexible seal 145, and the flexible seal 145 is made of silicone; the vacuum pump 143 is connected to the end of the dehumidification tube 141 through a pipeline to extract moisture.

[0032] In order to facilitate the assembly of the multi-layer corrugated mesh plate 142, the dehumidification pipe 141 is a connecting pipe with a round outer surface and a square inner surface, and the hanging groove 1411 is set obliquely downward. The hook 1421 of the multi-layer corrugated mesh plate 142 is hung on the hanging groove 1411, and then further connected using the flexible sealing member 145. The dehumidification pipe 141 is threadedly connected to the sealing cover 120, and a sealing gasket is provided between the dehumidification pipe 141 and the sealing cover 120 to ensure sealing while facilitating assembly.

[0033] More specifically, the corrugated mesh plate 142 includes: a corrugated mesh plate body 1423 and a baffle 1422. The corrugated mesh plate body 1423 is provided with mesh holes distributed in an array; the baffle 1422 is arranged at the crest and trough positions of the corrugated mesh plate body 1423, and is arranged on the upper surface and lower surface of the corrugated mesh plate body 1423. The baffle 1422 is used to further form a turbulent flow between the corrugated mesh plates 142 and the corrugated mesh plates 142 to prevent the dialysis powder from being extracted. Specifically, the baffle 1422 in this embodiment is a U-shaped baffle or a V-shaped baffle.

[0034] The feed pipe 121 includes a Y-shaped feed main pipe 1211 and an air intake side pipe 1212. The air intake side pipe 1212 is connected to the air outlet branch of the air compressor. The air intake side pipe 1212 is connected to a solenoid valve. Since the humidity of the dialysate powder is relatively high during feeding, the powder is easily adhered to the feed pipe 121. Therefore, after the feeding is completed, the air intake side pipe 1212 is used to spray high-pressure airflow to blow the adhesive powder on the tube wall into the interlayer heating and stirring barrel 110 for dehumidification and drying.

[0035] The stirring assembly 130 includes a stirring spindle 131 with stirring blades 132 spaced evenly apart. Stirring discs 133 are located at the top and bottom of the stirring spindle 131. The two stirring discs 133 are connected by an arc-shaped stirring member 134. The stirring discs 133 and the arc-shaped stirring member 134 are cylindrical in shape. To address the problem that existing sheet-shaped stirring members tend to stick to the dampness-rich dialysis powder, resulting in long dehumidification times and poor dehumidification results, this embodiment further configures the arc-shaped stirring member 134 with a hollow olive-shaped cross-section to reduce adhesion and improve the separation of bulk dialysis powder. Furthermore, a scraper 135 is provided on the outer wall of the stirring disc 133 to scrape away bulk dialysis powder.

[0036] Specifically, this embodiment also makes improvements to the stirring disk 133. The stirring disk 133 includes: a connecting disk 1331, a connecting rod 1332 and a connecting ring 1333. A connecting tube connected to the stirring main shaft 131 is provided in the middle of the connecting disk 1331. The connecting tube is frustum-shaped, so that the powder will not accumulate on the disk while ensuring a stable connection; the connecting rod 1332 is arranged on the outer ring side of the connecting disk 1331 and is radially connected to the connecting ring 1333. Compared with the original annular body, it is not easy to deform, and the connecting rod 1332 at the bottom is an arc-shaped connecting rod.

[0037] In summary, in this embodiment, the dialysis powder drying device is replaced with a water circulation constant temperature heating mode instead of the original electric heating plate mode. This heating method is gentler and does not cause yellowing of some dialysis powder. The dialysis powder is stirred in the interlayer heating and stirring barrel 110 for heat exchange and uniform heating. The moisture in the dialysis powder is heated to form water vapor and discharged from the dehumidification assembly 140. The dehumidification assembly 140 is also provided with multiple layers of corrugated mesh plates 142 and 142 and an annular vibrating member 144. The dialysis powder raised during the stirring and extraction process is blocked by the corrugated mesh plates 142. Since the humidity at the dehumidification outlet is high, powder agglomeration is easily caused. The annular vibrating member 144 is also provided on the outer wall of the tube. Through regular vibration, the agglomerated powder is re-entered into the interlayer heating and stirring barrel 110 for stirring, heating and dehumidification. The moisture content of the dialysis powder is reduced, and the agglomerated powder is automatically or passively dispersed, resulting in a fast and uniform dehumidification process.
