Description

Technical Field

[0001] This utility model relates to an unloading tower for salt production, belonging to the field of edible salt production equipment. Background Technology

[0002] The production process of iodized edible salt includes moistening, brine, crystallization, salt collection and washing. After the washing step, dehydration and drying are required. Drying is generally carried out by vibrating drying bed or drum dryer.

[0003] A drum dryer dries salt by having it come into counter-current contact with hot air inside an inclined rotating drum.

[0004] When edible salt is dried using a drum dryer, the drying temperature is around 110-210℃, while the indoor temperature is 20-55℃. The sudden drop in temperature will cause the edible salt to re-adhere to moisture. Moreover, if the temperature is too high, some chloride and sodium ions in the salt molecules will separate, forming sodium chloride and chlorine gas respectively. Chlorine gas is a yellow-green gas with a strong pungent odor at room temperature and pressure.

[0005] Therefore, this utility model provides a discharge tower for salt production with temperature regulation function and reduced material impact. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a roller shutter door controller that is compact in structure, easy to install, and small in overall size.

[0007] This utility model is implemented as follows:

[0008] A discharge tower for salt production includes a feeder, a drying drum, and a discharge tower. The drying drum is provided with a feeder for feeding wet materials and a discharge tower for discharging dry materials at its two ends.

[0009] The unloading tower includes a three-way valve, an air duct, a discharge port, a tower body, a first air outlet, and a second air outlet;

[0010] The bottom of the tower body is the discharge port, while the top has a first air outlet for dust discharge. The air duct is wrapped around the outer surface of the tower body and spirals upward. The bottom of the air duct is connected to the cold air zone and the hot air zone through a three-way valve, while the top of the air duct is the second air outlet.

[0011] The side of the tower body is connected to the drying drum.

[0012] As a further improvement, the tower body is provided with a waist-shaped inner liner, and the connection between the waist-shaped inner liner and the upper and lower ends of the tower body is connected by a sealing ring.

[0013] As a further improvement, the space between the waist-shaped inner liner and the tower body is a receiving cavity.

[0014] As a further improvement, the diameter of the waist-shaped inner liner in the middle is smaller than the diameter of the two ends of the waist-shaped inner liner.

[0015] As a further improvement, the space between the waist-shaped inner liner and the tower body is a layer of quartz stone.

[0016] As a further improvement, a cyclone dust collector is connected to the top of the tower body via a connecting pipe.

[0017] As a further improvement, a silencer is installed at the connection between the tower body and the connecting pipe via a threaded connection.

[0018] As a further improvement, the silencer includes a first air inlet, a cylinder body, an umbrella cap, and a third air outlet;

[0019] The cylinder has several umbrella caps arranged at equal intervals inside, and each umbrella cap has a vent at its tip.

[0020] The cylinder has a first air inlet and a third air outlet at both ends.

[0021] The beneficial effects of this utility model are:

[0022] ①This utility model uses cold air and hot air from the cold air zone and the hot air zone as the medium. When the tower temperature is high, cold air enters the air duct to cool it down. When the tower temperature is too low, hot air enters the air duct to heat it up, so that the tower temperature is maintained at 55℃-100℃, so that the dried edible salt granules will not become damp again, and the temperature of the edible salt granules gradually decreases.

[0023] ②The diameter of the waist-shaped inner liner in the middle of this utility model is smaller than the diameter of the two ends of the waist-shaped inner liner, so that the thickness of the unloading tower and the drying drum at the same position is greater than that on both sides. The dried edible salt will directly impact the inner wall at this point, reducing the wear and tear on the unloading drum.

[0024] ③ This utility model uses a fan to draw gas from inside the tower body, including but not limited to chlorine gas. The design of the silencer causes the drawn air to move in a circular motion in the umbrella cap, generating a vortex, reducing the pressure in the center and slowing down the gas outflow speed, thereby reducing noise. Since the granules of table salt contain sand and other impurities, it needs to be checked and maintained monthly. If blockage occurs, it needs to be cleaned in time. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] Reference Figures 1-4As shown in the figure, this embodiment provides a specific implementation of a discharge tower for salt production, including a feeder 10, a drying drum 20, and a discharge tower 30. The drying drum 20 is provided with a feeder 10 for feeding wet materials and a discharge tower 30 for discharging dry materials at both ends. The wet materials enter the drying drum 20 through the feeder 10. The drying drum 20, which is connected to the heat source zone 40, rotates under the drive of a motor, gradually drying the materials. The dried materials are discharged through the discharge tower 30. The motor is not shown in the figure. The materials mentioned here refer to edible salt granules.

[0033] The unloading tower 30 includes a three-way valve 301, an air duct 302, a discharge port 303, a tower body 304, a first air outlet 305, and a second air outlet 306.

[0034] The bottom of the tower body 304 is a discharge port 303, while the top has a first air outlet 305 for dust discharge. The air duct 302 is spirally arranged around the outer surface of the tower body 304. The bottom of the air duct 302 is connected to the cold air zone and the hot air zone through a three-way valve 301, while the top of the air duct 302 is a second air outlet 306. The side of the tower body 304 is connected to the drying drum 20.

[0035] Using cold and hot air from the cold and hot air zones as the medium, when the temperature of the tower body 304 is high, cold air enters the air duct 302 to cool it down; when the temperature of the tower body 304 is too low, hot air enters the air duct 302 to raise the temperature, so that the temperature of the tower body 304 is maintained at 55℃-100℃, preventing the dried salt granules from becoming damp again, and the temperature of the salt granules gradually decreases.

[0036] Furthermore, the tower body 304 is provided with a waist-shaped inner liner 309. The connection between the waist-shaped inner liner 309 and the upper and lower ends of the tower body 304 is connected by a sealing ring 311. Furthermore, the diameter of the waist-shaped inner liner 309 in the middle is smaller than the diameter of the two ends of the waist-shaped inner liner 309, so that the thickness of the unloading tower 30 and the drying drum 20 at the same position is greater than that on both sides. The dried edible salt will directly impact the inner wall at this point, reducing the wear of the unloading drum.

[0037] In one specific embodiment, the space between the waist-shaped inner liner 309 and the tower body 304 is a accommodating cavity 310, which contains no filling material but only air, making it easier to conduct heat and facilitating external air ducts 302 to cool or heat the tower body 304.

[0038] In one specific embodiment, the space between the waist-shaped inner liner 309 and the tower body 304 is a quartz layer. Quartz has a good thermal conductivity, making it easier to conduct heat and facilitating the external air duct 302 to cool or heat the tower body 304.

[0039] In one specific embodiment, the gap between the waist-shaped inner liner 309 and the tower body 304 is 2-5cm, which will not affect heat transfer and has a good impact resistance effect.

[0040] In one specific embodiment, both the waist-shaped inner liner 309 and the tower body 304 are made of stainless steel, which has a high thermal conductivity and is resistant to hydrochloric acid.

[0041] In one specific embodiment of this utility model, the top of the tower body 304 is connected to a cyclone dust collector 50 via a connecting pipe. The cyclone dust collector is a type of dust removal device. The dust removal mechanism involves causing the dust-laden airflow to rotate, using centrifugal force to separate dust particles from the airflow and collect them on the wall of the device. Then, gravity causes the dust particles to fall into the ash hopper, thus removing sand and other particles from the dried material.

[0042] In one possible specific embodiment of this utility model, a silencer 307 is installed at the connection between the tower body 304 and the connecting pipe by means of a threaded connection.

[0043] Furthermore, the silencer 307 includes a first air inlet 371, a cylinder 372, an umbrella cap 373, and a third air outlet 374;

[0044] The cylinder 372 has several umbrella caps 373 arranged at equal intervals inside, and each umbrella cap 373 has a vent hole at the tip of its umbrella.

[0045] The cylinder 372 has a first air inlet 371 and a third air outlet 374 at both ends.

[0046] The gas inside the tower body 304, including but not limited to chlorine, is drawn in by a fan. The design of the silencer causes the drawn air to move in a circular motion in the umbrella cap 373, generating a vortex, reducing the pressure in the central part, and slowing down the gas outflow speed, thereby reducing noise. Since the granules of table salt contain sand and other impurities, it is necessary to check and maintain them monthly. If blockage occurs, it needs to be cleaned in time.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
