[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. For the sodium para - aminosalicylate production drying device of the present utility model, the sodium para - aminosalicylate is guided into the interior of the heating cylinder through the feeding pipe. At the same time, the second motor is used to rotate the stirring and heat - conducting rod, so that the stirring plate on the outer surface of the stirring and heat - conducting rod stirs the sodium para - aminosalicylate inside the heating cylinder. At the same time, the second heater is used to heat the interior of the stirring and heat - conducting rod at a high temperature. Then, the heat source on the surface of the stirring and heat - conducting rod is transferred by the heat - conducting rod on the outer surface of the stirring and heat - conducting rod, so that the stirring and heat - conducting rod and the heat - conducting rod come into contact with the sodium para - aminosalicylate, and the heat source on the surfaces of the stirring and heat - conducting rod is transferred into the interior of the sodium para - aminosalicylate.

[0028] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.

[0029] As Figures 1 to 8 shown, a sodium aminosalicylate production and drying device according to an embodiment of the present utility model includes a drying oven 11 and a heating cylinder 12 fixedly installed on the inner side wall surface of the drying oven 11. A feed pipe 13 is fixedly installed on one side surface of the heating cylinder 12 and at the top edge position. A motor 2 121 is fixedly installed on the outer side surface of the heating cylinder 12 and at the bottom edge position of the feed pipe 13. A stirring heat conduction rod 124 is fixedly connected to the output end of the motor 2 121. A heater 2 125 movably sleeved on the outer side surface of the heating cylinder 12 is fixedly installed at the other end of the stirring heat conduction rod 124. A heat conduction rod 126 is fixedly connected to the outer side surface of the stirring heat conduction rod 124. A stirring plate 127 is fixedly installed on the outer side surface of the heat conduction rod 126;

[0030] Cooperate with the feed pipe 13 to guide sodium aminosalicylate into the interior of the heating cylinder 12. At the same time, cooperate with the motor 2 121 to rotate the stirring heat conduction rod 124, so that the stirring plate 127 on the outer side surface of the stirring heat conduction rod 124 turns and stirs the sodium aminosalicylate inside the heating cylinder 12. At the same time, cooperate with the heater 2 125 to heat the interior of the stirring heat conduction rod 124 at a high temperature. At the same time, use the heat conduction rod 126 on the outer side surface of the stirring heat conduction rod 124 to transfer the heat source on the surface of the stirring heat conduction rod 124, so that the stirring heat conduction rod 124 and the heat conduction rod 126 come into contact with the sodium aminosalicylate, and the heat source on the surfaces of the stirring heat conduction rod 124 and the heat conduction rod 126 is transferred into the interior of the sodium aminosalicylate. Then, use the continuous stirring of the stirring plate 127 to effectively mix the heated sodium aminosalicylate with the unheated sodium aminosalicylate. As the heat source inside the sodium aminosalicylate is continuously heated, the excess water vapor inside the sodium aminosalicylate gradually dissipates, achieving the effect of continuously stirring the sodium aminosalicylate with the stirring blades, and using the continuous stirring of the sodium aminosalicylate to dissipate the excess water vapor inside the sodium aminosalicylate, thereby reducing the water vapor inside the sodium aminosalicylate.

[0031] As Figures 1 to 8 shown, a limiting collar 129 is fixedly connected to one end of the heat conduction rod 126. A one-way discharge net 122 is arranged on the outer surface of the heating cylinder 12 and at a side edge position of the second heater 125. A closing cover 123 is detachably installed on the top surface of the heating cylinder 12. A limiting arc plate 1210 fixedly connected to the inner wall surface of the top of the closing cover 123 is movably sleeved on the outer surface of the limiting collar 129. Motors 115 are detachably installed on both side surfaces of the drying box 11 and at the upper and lower edge positions. A threaded rod 116 is fixedly installed at the output end of the motor 115, and the surface of the threaded rod 116 extends to the inner wall surface of the drying box 11. A push plate 117 is threadedly and movably sleeved on the outer surface of the threaded rod 116, and the outer surface of the push plate 117 is movably sleeved on the outer surfaces of the heating cylinder 12 and the closing cover 123. A discharge pipe 111 is fixedly installed on the outer surface of the drying box 11 and at a side edge position of the second heater 125. A closing door 112 is movably sleeved on the top surface of the discharge pipe 111. Extrusion and push cavities 14 and pressure loss cavities 15 are respectively arranged on the inner wall surface of the bottom of the drying box 11 and at both side edge positions of the push plate 117;

[0032] When the sodium salicylate inside the heating cylinder 12 is heated and dried to a certain extent, the motor 115 rotates the threaded rod 116, thereby driving the push plate 117 on the outer surface of the threaded rod 116 to slide back and forth left and right on the surfaces of the heating cylinder 12 and the closing cover 123. When the push plate 117 moves towards the direction of the motor 121, a pressure loss cavity 15 and a squeezing and pushing cavity 14 are formed on both side surfaces of the push plate 117. When the push plate 117 moves towards the direction of the pressure loss cavity 15, the internal space of the pressure loss cavity 15 is squeezed, while the space inside the squeezing and pushing cavity 14 on the other side surface of the push plate 117 will be continuously enlarged, resulting in a pressure loss inside the squeezing and pushing cavity 14. Due to the pressure imbalance between the space inside the squeezing and pushing cavity 14 and the pressure inside the heating cylinder 12, under the push of the pressure, the sodium salicylate accumulated at the inner bottom of the heating cylinder 12 is directly discharged and squeezed into the inside of the squeezing and pushing cavity 14. When the push plate 117 pushes towards the direction of the squeezing and pushing cavity 14, the space inside the squeezing and pushing cavity 14 will be directly compressed. Since the one-way discharge net 122 is for one-way discharge, by opening the closing door 112 and under the push of the push plate 117, the sodium salicylate inside the drying box 11 will pass through the discharge pipe 111 and be discharged, achieving the effect of unidirectionally extracting the dried sodium salicylate by squeezing, and then quickly squeezing and discharging the sodium salicylate. This reduces the need to open the equipment to collect traditional sodium salicylate, which may cause water vapor in the external space to re-permeate into the inside of the sodium salicylate, resulting in an increase in the humidity of the sodium salicylate, and the increase in water vapor will also affect the quality of the sodium salicylate.

[0033] As Figures 1 to 6 shown, a first heater 113 is fixedly installed on the back surface of the drying box 11. Two groups of heat conduction pipes 114 are respectively fixedly installed on the output end and the input end of the first heater 113. One end of the heat conduction pipe 114 is fixedly installed on the outer surface of the closing cover 123;

[0034] When the water vapor inside the sodium salicylate is emitted, the emitted water vapor will accumulate in the inner space at the top of the closed cover 123, and the heater 113 is cooperated to blow air into the heat pipe 114 to blow the water vapor accumulated on the top of the closed cover 123. With the continuous blowing of the airflow, the water vapor will enter the interior of the heat pipe 114 along with the airflow, and the hot air will be infused into the interior of the heater 113. The heater 113 is cooperated to heat the water vapor inside the hot air flow at high temperature and clean it up, and the gas heated by high temperature will re-enter the interior of the heat pipe 114, and the high-temperature heat source can maintain the heat source environment inside the heating tube 12, thereby keeping the sodium salicylate in a high-temperature environment at all times, thereby achieving the effect of using the hot air flow to circulate inside the heating tube 12, cooperating with the heater 113 to clean the water vapor inside the airflow, and then re-infusing the hot air flow into the heating tube 12, thereby keeping the interior of the heating tube 12 in a high-temperature environment at all times.

[0035] Working principle: cooperate with the feed pipe 13 to guide the sodium salicylate into the interior of the heating tube 12, and cooperate with the motor 121 to rotate the stirring heat-conducting rod 124, so that the stirring plate 127 on the outer surface of the stirring heat-conducting rod 124 turns and stirs the sodium salicylate in the heating tube 12, and cooperate with the heater 125 to heat the interior of the stirring heat-conducting rod 124 at high temperature, and then use the heat-conducting rod 126 on the outer surface of the stirring heat-conducting rod 124 to transfer the heat source on the surface of the stirring heat-conducting rod 124, so that the stirring heat-conducting rod 124 and the heat-conducting rod 126 are connected. The sodium salicylate is contacted with the stirring plate 127, so that the heat source on the surfaces of the stirring heat-conducting rod 124 and the heat-conducting rod 126 is transferred into the interior of the sodium salicylate, and then the heated sodium salicylate is effectively mixed with the unheated sodium salicylate by continuous stirring of the stirring plate 127. As the heat source inside the sodium salicylate is continuously heated, the excess water vapor inside the sodium salicylate is gradually dissipated, so that the sodium salicylate is continuously stirred by the stirring blades, and the excess water vapor inside the sodium salicylate is dissipated by the continuous stirring of the sodium salicylate, thereby reducing the water vapor inside the sodium salicylate.

[0036] After the water vapor inside the sodium salicylate is emitted, the emitted water vapor will accumulate in the space inside the top of the closed cover 123. The heater 113 is cooperated to blow air into the heat pipe 114 to blow the water vapor accumulated on the top of the closed cover 123. With the continuous blowing of the airflow, the water vapor will enter the heat pipe 114 along with the airflow, and the hot air will be injected into the heater 113. The water vapor inside the hot air flow is heated and cleaned by the heater 113, and the gas heated by the high temperature will re-enter the heat pipe 114. The high-temperature heat source can maintain the heat source environment inside the heating tube 12, thereby keeping the sodium salicylate in a high-temperature environment all the time, so as to achieve the effect of using the hot air flow to circulate inside the heating tube 12, cooperating with the heater 113 to clean the water vapor inside the air flow, and then injecting the hot air flow back into the heating tube 12, thereby keeping the heating tube 12 in a high-temperature environment all the time.

[0037] When the water vapor inside the sodium salicylate is emitted, the emitted water vapor will accumulate in the inner space at the top of the closed cover 123, and the heater 113 is cooperated to blow air into the heat pipe 114 to blow the water vapor accumulated on the top of the closed cover 123. With the continuous blowing of the airflow, the water vapor will enter the interior of the heat pipe 114 along with the airflow, and the hot air will be infused into the interior of the heater 113. The heater 113 is cooperated to heat the water vapor inside the hot air flow at high temperature and clean it up, and the gas heated by high temperature will re-enter the interior of the heat pipe 114, and the high-temperature heat source can maintain the heat source environment inside the heating tube 12, thereby keeping the sodium salicylate in a high-temperature environment at all times, thereby achieving the effect of using the hot air flow to circulate inside the heating tube 12, cooperating with the heater 113 to clean the water vapor inside the airflow, and then re-infusing the hot air flow into the heating tube 12, thereby keeping the interior of the heating tube 12 in a high-temperature environment at all times.
