Description

Technical Field

[0001] This utility model relates to the field of material drying technology, and in particular to a material dryer. Background Technology

[0002] In industrial production, drying ferric phosphate filter cake is a crucial process. This process typically requires specialized material dryers. Currently, one of the most commonly used drying devices is the paddle dryer.

[0003] The paddle dryer is a horizontal, stirred drying device that primarily uses heat conduction as its heat transfer method. Structurally, it features carefully designed stirring blades. During operation, these blades continuously propel the material within the drying chamber. This type of paddle dryer achieves its drying function mainly through indirect heating via heat conduction. Specifically, when the equipment starts, the heat carrier transfers heat to the heated surfaces of the equipment, while the wet material, stirred by the paddle blades, makes full and comprehensive contact with the heat carrier and heated surfaces. Through this continuous heat exchange, the moisture in the material gradually evaporates, thus achieving the drying purpose.

[0004] However, this type of paddle dryer also has some problems that urgently need to be solved in actual use. First, it cannot automatically discharge material according to the drying capacity of the machine. This means that in actual production, the amount of material fed must be manually controlled. If too much material is fed, exceeding the drying capacity of the equipment, the accumulation of material inside the equipment will hinder the effective transfer of heat and increase the operating load of the equipment, easily leading to equipment failure, such as motor overheating, accelerated wear of transmission components, etc., seriously affecting the normal operation and service life of the equipment. Conversely, if too little material is fed, the internal space of the equipment will not be fully utilized, the contact area between the heat carrier and the material will be relatively reduced, and the heat energy will not be fully utilized, which will easily affect the drying efficiency of the material, leading to a longer production cycle and increased production costs.

[0005] Furthermore, during the material drying process, hot air inside the drying chamber can easily leak out from the feed inlet. This is because the feed inlet needs to remain open at some point during equipment operation to allow material to enter, which provides a channel for hot air leakage. Hot air leakage not only wastes thermal energy and increases energy consumption, but also leads to unstable temperature and humidity environments within the drying chamber, thereby affecting the uniformity and efficiency of material drying and reducing product quality. Utility Model Content

[0006] In view of this, the purpose of this utility model is to overcome the shortcomings in related technologies, and this utility model provides a material dryer.

[0007] This utility model provides the following technical solution:

[0008] A material dryer includes a body, a heating component, a feeding pipe, a discharging component, and a control module.

[0009] The machine body is equipped with a stirring assembly; the heating assembly is mounted on the machine body for heating the drying chamber; the feeding pipe is vertically positioned above and connected to the feeding inlet of the machine body; the end of the conveyor belt for conveying materials is located above the upper opening of the feeding pipe. The discharging assembly includes a flap and a driving component, the driving component being kinetically connected to the flap, and the flap being disposed within the feeding pipe; the control module is electrically connected to the driving component, and the control module can send commands to the driving component to drive it to move, thereby controlling the flap to block or open the feeding pipe.

[0010] As a further improvement to the above technical solution, a dust cover is continuously provided above the conveyor belt and the feeding pipe.

[0011] As a further improvement to the above technical solution, the driving component includes a driving cylinder, the cylinder body of the driving cylinder is hinged to the machine body, one end of the flap near the driving cylinder is hinged to the inner wall of the feed pipe, and the telescopic rod of the driving cylinder is throttle-connected to the flap; the telescopic rod extends and retracts relative to the cylinder body, which can drive the flap to flip relative to the feed pipe.

[0012] As a further improvement to the above technical solution, the end of the flap near the drive cylinder is provided with a transmission rod, and a collar is hinged to the telescopic rod of the drive cylinder, and the collar is sleeved on the transmission rod.

[0013] As a further improvement to the above technical solution, a grid plate is also horizontally provided inside the feeding pipe, and the grid plate is located above the feeding assembly.

[0014] As a further improvement to the above technical solution, a crushing component is also provided inside the feeding pipe, and the crushing component is disposed between the grid plate and the discharge component.

[0015] As a further improvement to the above technical solution, the crushing component includes crushing blades and a drive motor. The crushing blades are disposed inside the feed pipe, and the drive motor is mounted on the feed pipe and is connected to the crushing blades in a transmission manner. The drive motor is used to drive the crushing blades to rotate.

[0016] As a further improvement to the above technical solution, the crushing assembly also includes a transmission box, which is installed at the lower end of the grid plate. The crushing blades are provided with a first bevel gear, and the shaft of the drive motor is provided with a second bevel gear. The first bevel gear and the second bevel gear are both located inside the transmission box and mesh with each other.

[0017] As a further improvement to the above technical solution, the heating component includes a hot air blower, and the body is provided with an air inlet and an air outlet at both ends of the side wall, and the air inlet is connected to the hot air blower.

[0018] As a further improvement to the above technical solution, the air inlet of the hot air blower is connected to a filter.

[0019] As a further improvement to the above technical solution, the air outlet is equipped with an exhaust pump.

[0020] Compared with related technologies, the beneficial effects of this utility model are:

[0021] In practical use, the material dryer provided by this utility model requires the operator to first activate the heating element on the machine to preheat it. This step ensures that the drying chamber reaches a suitable temperature, laying a good foundation for the subsequent material drying process. Simultaneously or shortly after the heating element preheats, the operator also needs to activate the stirring element inside the machine. Activating the stirring element ensures that the material is heated evenly during the drying process, thereby improving drying efficiency and quality.

[0022] Once the heating components have preheated and the stirring components are operating stably, the operator can use a conveyor belt or other conveying equipment to transport the material to be dried into the feed pipe. At this time, the control module drives the flap of the discharge component located in the feed channel to open, ensuring that the material can pass through the feed channel smoothly and enter the drying chamber of the machine. Inside the drying chamber, the material will be heated by the heating components, and the stirring components will continuously stir it, ensuring that the material is heated evenly, thereby achieving a highly efficient drying effect.

[0023] After a period of heating and drying, the material will be discharged through the machine's outlet. During this process, since the material conveying speed of the conveyor belt and other conveying equipment remains relatively constant, the operator can set a preset time on the control module. This preset time setting aims to ensure that after a certain amount of material has been fed into the drying chamber, the control module can automatically control the flap of the feeding component to close at a set time. This design avoids overfeeding, thus preventing damage to the equipment due to exceeding its drying capacity; at the same time, it also avoids underfeeding, which would affect the drying efficiency of the material. Through the automatic timed feeding control method, this invention can always maintain the optimal working state of the material drying process, ensuring work efficiency.

[0024] Furthermore, when the flap of the feeding component is in a state of blocking the feeding channel, it can effectively reduce the leakage of hot air in the drying chamber and ensure that the pressure in the drying chamber of the machine is always greater than the external atmospheric pressure, thereby reducing the probability of cold air entering the drying chamber and increasing the rate of airflow carrying moisture out, thus ensuring the drying effect of this invention on the material.

[0036] Combination Figure 1 , Figure 2 As shown, an embodiment of this utility model provides a material dryer, including a machine body 100, a heating component 200, a feeding pipe 300, a discharging component 400, and a control module.

[0037] The machine body 100 is equipped with a stirring assembly; the heating assembly 200 is disposed on the machine body 100 for heating the drying chamber of the machine body 100; the feeding pipe 300 is vertically disposed above the feeding port 110 of the machine body 100 and is connected to the feeding port 110; the end of the conveyor belt 910 for conveying materials is located above the upper opening of the feeding pipe 300. The discharging assembly 400 includes a flap 410 and a driving component, the driving component being pulsatorically connected to the flap 410, the flap 410 being disposed within the feeding pipe 300; the control module is electrically connected to the driving component, the control module being able to send commands to the driving component to drive the driving component to move, thereby controlling the flap 410 to block or open the feeding pipe 300; the control module, as the core control unit for the operation of the entire equipment, specifically comprises a series of key electronic components such as control chips and timers. These electronic components cooperate with each other to ensure that the control module can accurately and efficiently execute various control tasks.

[0038] In actual operation, operators possess a high degree of autonomy, enabling them to flexibly input various types of data into the control chip based on specific production needs and equipment operating conditions. Timing data is a commonly used type; operators can set specific time parameters, such as the duration and interval for the drive to open or close, so that the drive automatically performs the corresponding action at preset times. Opening / closing command data is equally indispensable. By inputting such commands, operators can precisely control the drive to open or close, thereby meeting the requirements of different process stages regarding the drive's operational status.

[0039] In actual use, the operator first needs to activate the heating element 200 on the machine body 100 to preheat it. This step ensures that the drying chamber reaches a suitable temperature, laying a good foundation for the subsequent material drying process. Simultaneously or shortly after the heating element 200 preheats, the operator also needs to activate the stirring element inside the machine body 100. Activating the stirring element aims to ensure that the material is heated evenly during the drying process, thereby improving drying efficiency and quality.

[0040] Once the heating element 200 has preheated and the stirring element is operating stably, the operator can use conveying equipment such as the conveyor belt 910 to transport the material to be dried into the feed pipe 300. At this time, the control module drives the flap 410 of the discharge element 400 located in the feed channel to open, ensuring that the material can pass smoothly through the feed channel and smoothly enter the drying chamber of the machine body 100. Inside the drying chamber, the material will be heated by the heating element 200, and the stirring element will also continuously stir, so that the material is heated evenly, thereby achieving a highly efficient drying effect.

[0041] After a period of heating and drying, the material will be discharged through the outlet 120 of the machine body 100. During this process, since the material conveying speed of the conveying equipment such as the conveyor belt 910 remains basically constant, the operator can set a preset time on the control module. This preset time setting is designed to ensure that after a certain amount of material has been fed into the drying chamber, the control module can automatically control the flap 410 of the feeding component to close at a set time. This design avoids excessive material feeding into the machine body 100, thus preventing damage to the equipment due to exceeding its drying capacity; at the same time, it also avoids insufficient material feeding, which would affect the drying efficiency of the material. Through the automatic timed material feeding control method, this embodiment can always maintain the optimal working state of the material drying process, ensuring work efficiency.

[0042] Furthermore, when the flap 410 of the feeding assembly 400 is in a state of blocking the feeding channel, it can effectively reduce the leakage of hot air in the drying chamber and ensure that the pressure in the drying chamber of the machine body 100 is always greater than the external atmospheric pressure, thereby reducing the probability of cold air entering the drying chamber and increasing the rate of airflow carrying water vapor to be discharged, thus ensuring the drying effect of this utility model on the material.

[0043] In some specific embodiments, a dust cover 920 is continuously installed above the conveyor belt 910 and the feed pipe 300. In actual production, the external environment often presents many uncertainties, such as dust, debris, and other foreign objects that may fall at any time. Without the protection of the dust cover 920, these foreign objects are highly likely to fall onto the conveyor belt 910 and mix into the material as the conveyor belt 910 operates; or they may fall into the feed pipe 300, contaminating the material before it enters equipment such as the dryer. Once foreign objects mix into the material, it will seriously affect the overall quality of the material, potentially leading to defects in subsequently produced products, and even affecting the product's performance and safety.

[0044] Furthermore, during material transportation, especially for granular or powdery materials, dust particles are easily splashed. These splashed dust particles not only waste materials and increase production costs, but also spread into the surrounding environment, polluting air quality, affecting the cleanliness of the production environment, and impacting the health of operators. The dust cover 920 effectively blocks the splashing of dust particles, confining them to the area covered by the conveyor belt 910 and the feed pipe 300, avoiding material waste, protecting the production environment, and meeting environmental protection requirements.

[0045] In some specific embodiments, the driving component includes a driving cylinder 420, the cylinder body of which is hinged to the machine body 100, and the end of the flap 410 near the driving cylinder 420 is hinged to the inner wall of the feed pipe 300. The telescopic rod of the driving cylinder 420 is throttle-connected to the flap 410. The telescopic rod extends and retracts relative to the cylinder body, which can drive the flap 410 to flip relative to the feed pipe 300. The driving cylinder 420 has the advantages of reliable support and sensitive response, which facilitates the rapid and efficient driving of the flap 410.

[0046] In some specific embodiments, the end of the flap 410 near the drive cylinder 420 is provided with a transmission rod 411, and a collar 421 is hinged to the telescopic rod of the drive cylinder 420, the collar 421 being sleeved on the transmission rod 411. During actual operation, the drive cylinder 420 needs to drive the flap 410 to flip, thereby opening or closing the feeding channel. If the transmission structure is not designed properly, a transmission dead point can easily occur. A transmission dead point will prevent the force of the drive cylinder 420 from being effectively transmitted to the flap 410, causing the flap 410 to fail to flip as expected, thus affecting the normal operation of the entire feeding assembly 400.

[0047] By ingeniously designing a transmission rod 411 and hinged a collar 421 to the telescopic rod of the drive cylinder 420, which is then fitted onto the transmission rod 411, the problem of transmission dead points when the drive cylinder 420 drives the flap 410 to flip can be effectively avoided. In this way, regardless of the telescopic movement of the drive cylinder 420, the force can be stably and smoothly transmitted to the flap 410 through the cooperation of the collar 421 and the transmission rod 411, ensuring the high reliability and stability of the feeding assembly 400 during use, thereby guaranteeing the normal operation of the entire material dryer.

[0048] In some specific embodiments, a grid plate 500 is horizontally installed inside the feed pipe 300, and the grid plate 500 is located above the discharge assembly 400. During actual material conveying, the material falls from a height along the feed pipe 300. When the material passes through the grid plate 500, the grid plate 500 plays a unique role. Due to the multiple regular or irregular grid gaps on the surface of the grid plate 500, the material collides and interacts with the grid plate 500 during its fall, thus providing a buffering effect. This buffering effect can reduce the speed and impact force of the falling material, preventing the material from directly impacting the discharge assembly 400 or other components due to excessive falling speed, thus avoiding equipment damage.

[0049] Meanwhile, the grating plate 500 also disperses the material. Material clumps that might otherwise clump together are broken and dispersed by the gaps in the grating plate 500, making the material looser and more uniform. This buffering and dispersing effect is particularly important during continuous material flow. It effectively prevents uneven material distribution within the feed pipe 300, avoiding excessive material accumulation in some areas and insufficient material in others.

[0050] More importantly, the buffering and dispersing effect of the grating plate 500 can prevent material bridging from hindering its flow. Material bridging refers to the formation of a bridge-like structure within the pipe, obstructing the normal flow of subsequent materials. By altering the flow state of the material, the grating plate 500 disrupts the conditions for bridging, ensuring that the material can smoothly pass through the feed pipe 300 and enter subsequent drying chambers and other equipment for processing, thereby guaranteeing the stable operation of the entire material dryer.

[0051] In some specific embodiments, the feed pipe 300 is further provided with a crushing component 600, which is disposed between the grid plate 500 and the discharge component 400. The grid plate 500 plays a preliminary buffering and dispersing role during material conveying, but some materials may still form clumps due to their own characteristics or external factors. The discharge component 400 is mainly responsible for controlling the timing and flow rate of material entry, and does not have a crushing function for clumped materials.

[0052] The existence of the crushing component 600 is precisely to compensate for the deficiencies in this stage. When the material, after preliminary treatment by the grating plate 500, continues to fall and enters the area where the crushing component 600 is located, the crushing component 600 plays its crucial role. It can crush and disperse agglomerated materials. Through a specific crushing structure and operating mode, the originally larger agglomerated materials are crushed into smaller particles or powder, increasing the gaps between material particles and increasing the surface area.

[0053] In this way, when the material successfully passes through the feeding assembly 400 and finally enters the drying chamber of the machine body 100, the smaller and more uniform material particles result in a larger contact area with the hot air and higher heat transfer efficiency, thus enabling more efficient drying. This not only shortens the drying time and improves production efficiency but also ensures the uniformity of material drying and enhances the quality of the final product.

[0054] In some specific embodiments, the crushing assembly 600 includes crushing blades 610 and a drive motor 620. The crushing blades 610 are disposed inside the feed pipe 300, and the drive motor 620 is mounted on the feed pipe 300 and is connected to the crushing blades 610 in a transmission manner. The drive motor 620 is used to drive the crushing blades 610 to rotate. By driving the crushing blades 610 to rotate through the drive motor 620, it is easier to achieve more reliable crushing and dispersion of materials.

[0055] In some specific embodiments, the crushing assembly 600 further includes a transmission box 630, which is installed at the lower end of the grid plate 500. The crushing blade 610 is provided with a first bevel gear 631, and the shaft of the drive motor 620 is provided with a second bevel gear 632. The first bevel gear 631 and the second bevel gear 632 are both located in the transmission box 630 and mesh with each other, which facilitates the improvement of the transmission reliability between the drive motor 620 and the crushing blade 610.

[0056] In some specific embodiments, the heating assembly 200 includes a hot air blower 210. The machine body 100 has an air inlet 130 and an air outlet 140 at both ends of its side wall, with the air inlet 130 connected to the hot air blower 210. During the material drying process, the hot air blower 210 continuously operates, inputting a stable hot airflow into the drying chamber of the machine body 100. Simultaneously, the stirring assembly inside the drying chamber rotates continuously under the drive of a motor, causing the material to tumble and flow within the drying chamber. The hot airflow and the stirring assembly work together; the hot airflow evenly coats the material, transferring heat to it, while the stirring assembly further promotes full contact between the material and the hot airflow, thereby achieving uniform heating and drying of the material within the machine body 100.

[0057] In some specific embodiments, the air inlet of the hot air blower 210 is connected to a filter 700. During actual operation, the hot air blower 210 needs to draw in air from the external environment, heat it, and then input it into the drying chamber of the machine body 100 to achieve the drying process of the material. However, the external environment often contains various impurities, such as dust, particulate matter, and fibers. If the hot air blower 210 directly draws in these airflows containing impurities, the impurities may enter the drying chamber with the hot airflow and come into contact with the material.

[0058] Once impurities are mixed into materials, they will have a serious impact on the production quality of the materials. For example, impurities may change the physical properties of the materials, affecting their appearance, purity, and subsequent processing performance; for some materials with extremely high cleanliness requirements, impurities may even lead to product defects and production losses.

[0059] By installing a filter 700 at the air inlet of the hot air blower 210, this situation can be effectively avoided. The filter 700 filters the airflow entering the hot air blower 210, intercepting impurities and allowing only clean airflow to pass through and enter the hot air blower 210. In this way, the airflow drawn into the hot air blower 210 is clean, and the hot airflow entering the drying chamber after heating will not carry impurities, thus ensuring that the material is not contaminated by impurities during the drying process, thereby guaranteeing the production quality of the material and improving the product qualification rate.

[0060] In some specific embodiments, the air outlet 140 is equipped with an exhaust pump 800 to improve the efficiency of exhausting the airflow carrying moisture and improve the heating and drying efficiency of the material in this embodiment.
