Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment technology, and more specifically to a drying device for producing zinc calcined sand. Background Technology

[0002] Zinc calcined ore is a product obtained by high-temperature oxidative roasting of zinc concentrate. It is one of the important raw materials for zinc smelting. Zinc calcined ore is a brown, micro-granular solid. As an intermediate product, it is an important raw material for the production of direct zinc oxide, electrolytic zinc, and electric furnace zinc powder. Market demand mainly comes from zinc smelters. As a raw material for zinc smelting, zinc concentrate is usually extracted from zinc ore through steps such as ore crushing and flotation. The ore is first crushed and ground to make its particle size suitable for flotation. Then, by adding appropriate amounts of collectors and frothing agents, the zinc minerals in the ore can float together with the froth to form zinc concentrate. After obtaining zinc concentrate, it needs to be dried and then roasted in a rotary kiln to form zinc calcined ore.

[0003] Insufficiency of existing technology: Existing drying equipment does not sufficiently bake and dry zinc concentrate, resulting in over-baking of the external zinc concentrate and insufficient drying of the internal zinc concentrate. This leads to the presence of other impurities in the mixture formed by adding auxiliary materials and mixing them evenly with zinc concentrate during the raw material preparation stage, which affects the reaction process and reduces the yield and quality of zinc calcined ore. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a drying device for producing zinc calcined sand, so as to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for producing zinc calcined sand, comprising a drying drum device, a steam tank device bolted to the top of the drying drum device, a drying auxiliary device connected to one end of the steam tank device via a pipe, a drum rotating device connected to the other end of the steam tank device via a pipe, the drying drum device comprising a drum shell, a magnetic flux tube bolted to the inside of the side of the drum shell, a supporting sliding block welded to the inside of the bottom of the drum shell, a rotating cylinder slidably connected to the top of the supporting sliding block, a gear ring provided in the middle of the side of the rotating cylinder, and a foot block bolted to the bottom of the drum shell.

[0006] Furthermore, the steam tank device includes a water tank, a steam outlet pipe is connected to a side pipe of the water tank, a first steam pipe is connected to one side pipe of the steam outlet pipe, a second steam pipe is connected to the other side pipe of the steam outlet pipe, and a roller shell is fixedly fitted to the side of the water tank.

[0007] Furthermore, the drying auxiliary device includes a first steam engine, with a track connected to the front rotating shaft of the first steam engine, and a second rotating shaft fixedly connected to the back of the bottom end of the first steam engine.

[0008] Furthermore, a fan is fixedly connected to one end of the second shaft, and a connecting plate is rotatably sleeved on the side of the second shaft.

[0009] Furthermore, the two ends of the connecting plate are bolted to the drum shell, and one end of the first steam engine is connected to the first gas pipe.

[0010] Furthermore, the drum rotating device includes a second steam engine, one end of which is connected to a second air pipe, and a starting gear is connected to the front rotating shaft of the second steam engine. The starting gear is meshed with a gear ring, and a drum shell is welded to the bottom of the second steam engine.

[0011] Furthermore, the first steam engine includes a first rotating shaft, one end of which is fixedly connected to a rotating wheel, and a rotating housing is rotatably sleeved on the side of the rotating wheel. An air inlet pipe is connected to one side of the rotating housing, and an exhaust pipe is connected to the other side of the rotating housing.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model incorporates a drying drum device that utilizes a flux tube to emit electromagnetic waves. These electromagnetic waves cause the surface moisture of the zinc concentrate to heat up and evaporate. The electromagnetic waves can penetrate the zinc concentrate, covering the zinc concentrate inside the drum under the electromagnetic field, thus drying the zinc concentrate inside the drum as well. Furthermore, water in a water tank is heated electromagnetically, and the steam generated by the boiling water has kinetic energy. This kinetic energy is used to rotate the drum, further dispersing the moisture evaporated from the zinc concentrate inside the drum. This invention effectively solves the problem of insufficient drying of zinc concentrate in existing drying devices, resulting in over-drying of the outer zinc concentrate while the inner zinc concentrate remains insufficiently dried, affecting the reaction process and reducing the yield and quality of zinc roasted ore.

[0014] 2. This utility model, by incorporating a drying auxiliary device, utilizes the steam from the water tank to rotate the impeller, and then uses the track to drive the fan in the drum to rotate, generating wind power to quickly blow the evaporated water vapor out of the drum, which helps to accelerate the drying process of zinc concentrate and improve the efficiency of zinc roasting.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The zinc calcination drying device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1 to 6 This utility model provides a drying device for producing zinc calcined sand, including a drying drum device 1, a steam tank device 2 bolted to the top of the drying drum device 1, a drying auxiliary device 3 connected to one end of the steam tank device 2 by a pipe, and a drum rotation device 4 connected to the other end of the steam tank device 2 by a pipe.

[0024] In this embodiment, it is necessary to further explain that the drying drum device 1 heats and evaporates the surface moisture of the zinc concentrate by emitting electromagnetic waves through a flux tube, and then rolls and dries the zinc concentrate to ensure thorough drying. The steam tank device 2 uses electromagnetic heating to boil the water in it and generate steam, and then uses the kinetic energy of the steam. The drying auxiliary device 3 uses the kinetic energy of the steam in the steam tank device 2 to rotate the fan and promote the drying process. The drum rotation device 4 uses the kinetic energy of the steam in the steam tank device 2 to rotate the drum in the drying drum device 1. The specific structure and working principle of the above components will be explained in detail later.

[0025] In a preferred embodiment, the drying drum device 1 includes a drum housing 101, a magnetic flux tube 102 is bolted to the inside of the side of the drum housing 101, a support sliding block 103 is welded to the inside of the bottom of the drum housing 101, a rotating drum 104 is slidably connected to the top of the support sliding block 103, a gear ring 105 is provided in the middle of the side of the rotating drum 104, and a foot block 106 is bolted to the bottom of the drum housing 101.

[0026] In this embodiment, it is necessary to further explain that electromagnetic waves are emitted by the flux tube 102. These electromagnetic waves cause the moisture on the surface of the zinc concentrate to heat up and evaporate. The electromagnetic waves can penetrate the zinc concentrate, and the zinc concentrate inside the rotating drum 104 is covered by the electromagnetic field, so that the zinc concentrate inside the rotating drum 104 is also dried. Then, water in the water tank is heated by electromagnetic heating. The steam generated by the boiling water has kinetic energy. This kinetic energy is used to rotate the rotating drum 104, thereby dissipating the water vapor evaporated from the zinc concentrate inside the drum. This helps to solve the problem that existing drying devices do not dry the zinc concentrate sufficiently, resulting in over-drying of the zinc concentrate on the outside while the zinc concentrate inside is not dried enough, which affects the reaction and reduces the yield and quality of zinc roasted ore.

[0027] In a preferred embodiment, the steam tank device 2 includes a water tank 201, a steam outlet pipe 202 connected to a side pipe of the water tank 201, a first steam pipe 203 connected to one side pipe of the steam outlet pipe 202, a second steam pipe 204 connected to the other side pipe of the steam outlet pipe 202, and a roller shell 101 fixedly sleeved on the side of the water tank 201.

[0028] In this embodiment, it should be specifically noted that the water tank 201 is located within the electromagnetic waves emitted by the flux tube 102.

[0029] In a preferred embodiment, the drying auxiliary device 3 includes a first steam engine 301, a track 302 connected to the front shaft of the first steam engine 301, a second shaft 303 fixedly connected to the back of the bottom end of the first steam engine 301, a fan 304 fixedly connected to one end of the second shaft 303, a connecting plate 305 rotatably sleeved on the side of the second shaft 303, a roller shell 101 bolted to both ends of the connecting plate 305, and a first air pipe 203 connected to one end of the first steam engine 301.

[0030] In this embodiment, it should be specifically explained that the steam from the water tank 201 is used to rotate the wheel, and the track 302 drives the fan 304 in the drum shell 101 to rotate and generate wind power, which quickly blows the evaporated water vapor in the drum 104 away from the drum 104, which helps to speed up the drying process of zinc concentrate and improve the efficiency of zinc roasting.

[0031] In a preferred embodiment, the drum rotating device 4 includes a second steam engine 401, one end of which is connected to a second air pipe 204, and a starting gear 402 is connected to the front rotating shaft of the second steam engine 401. The starting gear 402 is meshed with the gear ring 105, and a drum shell 101 is welded to the bottom of the second steam engine 401.

[0032] In a preferred embodiment, the first steam engine 301 includes a first rotating shaft 3011, one end of which is fixedly connected to a rotating wheel 3012, and a rotating housing 3013 is rotatably sleeved on the side of the rotating wheel 3012. An air inlet pipe 3014 is connected to one side of the rotating housing 3013, and an exhaust pipe 3015 is connected to the other side of the rotating housing 3013.

[0033] In this embodiment, it should be specifically noted that the structure of the second steam engine 401 is the same as that of the first steam engine 301.

[0034] The working principle of this invention is as follows: The magnetic flux tube 102 in the drying drum device 1 emits electromagnetic waves. The electromagnetic waves cause the moisture on the surface of the zinc concentrate to generate heat and evaporate. The electromagnetic waves can penetrate the zinc concentrate, and the zinc concentrate inside the rotating drum 104 is covered by the electromagnetic field, so that the zinc concentrate inside the rotating drum 104 is also dried. Then, water in the electromagnetic water tank 201 is added. The steam generated by the boiling water has kinetic energy. This kinetic energy is used to make the rotating drum 104 rotate, so that the water vapor evaporated from the zinc concentrate inside the drum can be dispersed. This helps to solve the problem that the existing drying device does not dry the zinc concentrate sufficiently, resulting in the zinc concentrate on the outside being over-dried while the zinc concentrate inside is not dried sufficiently, which affects the reaction and reduces the yield and quality of zinc roasted ore.

[0035] The first steam engine 301 uses steam from the water tank 201 to rotate the rotor 3012, and then uses the track 302 to drive the fan 304 in the drum shell 101 to rotate and generate wind power, which quickly blows the evaporated water vapor in the drum 104 away from the drum 104, which helps to speed up the drying process of zinc concentrate and improve the efficiency of zinc roasting.
