Description

TECHNICAL FIELD

[0001] The utility model belongs to snow-melting agent drying technical field, specifically about a drying machine for snow-melting agent production. BACKGROUND

[0002] The drying machine for snow-melting agent production usually adopts the vibration fluidized bed dryer. The vibration fluidized bed dryer generally makes the machine vibrate by the exciting force generated by the vibration motor, and the granulated snow-melting agent particles jump forward under the action of the exciting force in the given direction, while the hot air input by the hot air fan at the bottom of the bed makes the snow-melting agent in the fluidized state, so that the snow-melting agent particles fully contact with the hot air and carry out the intense heat and mass transfer process, thereby achieving the drying purpose.

[0003] However, in the drying process of the snow-melting agent, the snow-melting agent particles may be mutually adhered to form large lumps, which not only affects the drying efficiency but also may cause the vehicle to slip and increase the safety hazard. Under the action of vibration and friction, the particles may also produce fine particles, which may cause the snow-melting agent to drift during use, resulting in resource waste, and may also pollute the soil and water and pose a potential threat to the ecological environment.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a drying machine for snow-melting agent production. SUMMARY

Specific implementation

[0027] In order to make the person skilled in the art better understand the technical scheme in the present application, the technical scheme in the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.

[0028] As shown in Figures 1-2 The present application relates to a kind of dryers for snow-melting agent production in an embodiment of the present application, including vibration fluidized bed dryer body 1, general snow-melting agent production vibration fluidized bed dryer body 1 mainly by main machine box body (be divided into lower box body, vibration motor, punch auxiliary material plate, upper cover, air outlet, feed inlet, observation window, air inlet and discharge port etc.), heating system (dry hot air required heat source support kerosene point etc. multiple schemes, cyclone separation system, dust removal and wetting system, PLC control system etc. are made up of.Sending fan will air input air heater, provided hot air enters lower box body, snow-melting agent material is from feed inlet into vibration fluidized bed dryer body 1, hot air passes through the distribution plate of fluidized bed by from below to above vertical blowing, makes snow-melting agent material present boiling state, main machine is under the action of vibration motor excitation force uniform vibration, makes snow-melting agent material along horizontal throw, dried snow-melting agent is under the comprehensive action of hot air flow and mechanical vibration and forms fluidized state, makes snow-melting agent and hot air contact time long, area is big, to reach the effect of high-efficiency drying snow-melting agent, the upper cavity formed by exhaust pipe in main machine is extracted by induced draft fan, wet air is contained in material is recycled by cyclone separator, wet air is discharged into atmosphere by induced draft fan, dried material is discharged by discharge port.

[0029] As shown in Figures 1-2As shown, the vibrating fluidized bed dryer body 1 is provided with a perforated plate 101, the vibrating fluidized bed dryer body 1 comprises a shell, a drying assembly is arranged in the shell, a drying zone is formed by the drying assembly, the vibrating fluidized bed dryer body 1 is provided with a discharge pipe 102 at the bottom, a crushing mechanism is arranged at one end of the vibrating fluidized bed dryer body 1, and a second sieve plate 301 is arranged in the discharge pipe 102. The undried deicing agent particles are sent to the perforated plate 101 in the vibrating fluidized bed dryer body 1, and the vibrating motor, spring and air heater make the deicing agent on the perforated plate 101 in the drying zone flow to the crushing mechanism at one end of the drying zone, and at the same time, the deicing agent is dried. When the deicing agent is dried and reaches the crushing mechanism, the deicing agent that is not adhered passes through the crushing mechanism into the discharge pipe 102, and the large pieces of adhered deicing agent continue to move forward and are crushed at the crushing mechanism. To some extent, the use of large pieces of deicing agent can avoid vehicle skidding and cause safety hazards. The crushed deicing agent enters the discharge pipe 102, and the second sieve plate 301 in the discharge pipe 102 screens out the fine deicing agent, which can to some extent avoid the scattering of small particles of deicing agent when used, thereby causing environmental pollution.

[0030] As shown in Figure 2 , the crushing mechanism comprises a first sieve plate 201, the first sieve plate 201 is arranged at one end of the perforated plate 101, the top of the first sieve plate 201 is provided with a pressing plate 202, the pressing plate 202 is arranged in the vibrating fluidized bed dryer body 1, and the gap between the first sieve plate 201 and the pressing plate 202 away from one end of the perforated plate 101 gradually decreases to be consistent with the diameter of the deicing agent. After the deicing agent reaches the first sieve plate 201, the deicing agent that is not adhered passes through the first sieve plate 201 into the discharge pipe 102, and the large pieces of deicing agent continue to move forward. Since the gap between the first sieve plate 201 and the pressing plate 202 gradually decreases to be consistent with the diameter of the deicing agent, the large pieces of deicing agent are crushed by the first sieve plate 201 and the pressing plate 202 during the forward movement, and the deicing agent that is crushed to a qualified size passes through the first sieve plate 201 and is guided downward by the guide plate 203, and the unqualified deicing agent continues to be crushed.

[0031] As shown in Figure 2 , the second sieve plate 301 is arranged in the discharge pipe 102, the second sieve plate 301 is arranged inside the discharge pipe 102, and the second sieve plate 301 divides the discharge pipe 102 into a qualified area above and a small particle area below. After the deicing agent enters the discharge pipe 102, it slides onto the second sieve plate 301, the deicing agent with a small size enters the small particle area, and the deicing agent with a qualified size stays on the qualified area of the second sieve plate 301 for classification.

[0032] As shown in Figure 4 , the second sieve plate 301 is inclined downward away from one end of the vibrating fluidized bed dryer body 1. The downwardly inclined second sieve plate 301 can as much as possible avoid the blocking of deicing agent particles, thereby affecting the discharging efficiency.

[0033] As shown in Figures 2-5As shown, the vibrating fluidized bed dryer body 1 is provided with a blocking prevention mechanism matched with the crushing mechanism. The blocking prevention mechanism can avoid the accumulation of large lumps of snow melting agent at the crushing mechanism to some extent, and cannot be normally crushed.

[0034] As shown in the figure, Figures 3-5 The blocking prevention mechanism includes a connecting rod 204 fixedly connected to the extrusion plate 202, the connecting rod 204 is slidingly connected to the exhaust pipe at the top of the vibrating fluidized bed dryer body 1, and the connecting rod 204 is provided with a locking mechanism matched with the extrusion plate 202. When the crushing mechanism accumulates large lumps of snow melting agent and cannot be normally crushed, the locking mechanism is opened, and the connecting rod 204 is manually pressed downward, and then the extrusion plate 202 crushes the large lumps of snow melting agent.

[0035] As shown in the figure, Figure 3 The locking mechanism includes a first threaded piece 2041 installed on the outside of the connecting rod 204, and the vibrating fluidized bed dryer body 1 is provided with a second threaded piece 103 matched with the first threaded piece 2041 at the top of the exhaust pipe, and the second threaded piece 103 and the first threaded piece 2041 are provided with a nut 205. Turning the nut 205 makes the nut 205 away from the first threaded piece 2041 and the second threaded piece 103, that is, the fixing of the connecting rod 204 and the extrusion plate 202 is released.

[0036] As shown in the figure, Figures 1-4 As shown in the figure, the vibrating fluidized bed dryer body 1 is provided with a surface drying box 5 at one end, the surface drying box 5 is provided with a feeding mechanism, one end of the feeding mechanism extends into the vibrating fluidized bed dryer body 1, and the end of the feeding mechanism located in the vibrating fluidized bed dryer body 1 is located above the perforated plate 101. The snow melting agent that has not been dried is dried on the surface in the surface drying box 5, and then enters the vibrating fluidized bed dryer body 1 for fluidized drying, which can reduce the probability of mutual contact and adhesion of large lumps of snow melting agent during the fluidization process to some extent.

[0037] As shown in the figure, Figures 1-5 As shown in the figure, the vibrating fluidized bed dryer body 1 is provided with a surface drying box 5 at one end, the surface drying box 5 is provided with a feeding mechanism, one end of the feeding mechanism extends into the vibrating fluidized bed dryer body 1, and the end of the feeding mechanism located in the vibrating fluidized bed dryer body 1 is located above the perforated plate 101. The snow melting agent that has not been dried is dried on the surface in the surface drying box 5, and then enters the vibrating fluidized bed dryer body 1 for fluidized drying, which can reduce the probability of mutual contact and adhesion of large lumps of snow melting agent during the fluidization process to some extent.

[0038] As shown in the figure, Figure 5As shown, a plurality of heat absorption openings 1021 are formed in the discharge pipe 102, and the heat absorption openings 1021 are in communication with the heat collecting pipes 402. The heat absorption openings 1021 are provided with a filter screen (not shown in the figure) on the side close to the small particle area. The plurality of heat absorption openings 1021 can more fully collect heat and have higher heat utilization rate.

[0039] As shown in the figure, the heat absorption openings 1021 are located in the small particle area below the second sieve plate 301. The heat absorption openings 1021 located in the small particle area can improve the effect of separating the small particle deicing agent from the qualified deicing agent particles to some extent. Figure 5

[0040] As shown in the figure, the heat absorption openings 1021 are located in the small particle area below the second sieve plate 301. The heat absorption openings 1021 located in the small particle area can improve the effect of separating the small particle deicing agent from the qualified deicing agent particles to some extent. Figures 2-5 As shown in the figure, the heat absorption openings 1021 are located in the small particle area below the second sieve plate 301. The heat absorption openings 1021 located in the small particle area can improve the effect of separating the small particle deicing agent from the qualified deicing agent particles to some extent.

[0041] The model of the vibration fluidized bed dryer body 1 can be selected from the ZLG series vibration fluidized bed dryer, and the model of the air blower 401 can be selected from the 3L series Roots air blower. Different models can be selected according to actual market demand. The vibration fluidized bed dryer body 1 and the air blower 401 are electrically connected to an external power source. Since the vibration fluidized bed dryer body 1 and the air blower 401 are common devices for personnel in the field, their specific structure, switch mode, and working principle are not described in detail here.

[0042] During use, the deicing agent to be dried is sent into the surface drying box 5 for surface drying by the feeding mechanism, and the deicing agent after surface drying is sent into the vibration fluidized bed dryer body 1 for complete drying by the feeding mechanism. The deicing agent that is not adhered enters the discharge pipe 102, and the adhered deicing agent enters the crushing mechanism after being crushed and then enters the discharge pipe 102. The second sieve plate 301 in the discharge pipe 102 separates the deicing agent of qualified size from the small size deicing agent. To some extent, this avoids the difficulty of dispersing and dissolving large particle deicing agent during use, which leads to slow deicing speed, unsatisfactory effect, and tire skidding. Small particle deicing agent is easy to drift, which leads to uneven coverage of deicing agent on the road surface, reduces the deicing effect, and causes soil salinization and water pollution due to the entry of fine deicing agent particles into soil and water bodies along with rainwater runoff.
