Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically to a pigment drying device. Background Technology

[0002] In the production process of pigments or coatings, in order to ensure the quality and performance of the final pigment product and to facilitate storage and transportation, it is usually necessary to remove moisture or other solvents from the pigment, thus requiring the pigment to undergo drying treatment.

[0003] For example, patent CN212320244U provides a drying device for processing phthalocyanine blue pigment, including a housing, an air heater, and a motor. An air compressor is located at one corner of the upper part of the housing. An exhaust pipe is installed on one side wall of the air compressor, and a connecting pipe is installed on the side wall of the air compressor away from the exhaust pipe. The air heater is located at the end of the connecting pipe away from the air compressor, and an air inlet pipe is located at the end of the air heater away from the connecting pipe. This patent, by setting up an air compressor, air heater, connecting pipe, and air inlet pipe, allows the device to dry the pigment using clean, high-temperature air. With the assistance of the motor and stirring blades, the high-temperature air can be evenly distributed within the housing, resulting in more uniform drying of the phthalocyanine blue pigment. Furthermore, the exhaust pipe can be connected to heating pipes, allowing the waste heat of the device to be reused with the assistance of a high-temperature fan.

[0004] Under the high temperature of the aforementioned processing and drying device, the moisture in the pigment will be converted into water vapor and rise to be discharged. However, in this patent, the containers containing the pigment are stacked layer by layer on the wire mesh. The water vapor released from the pigment in the lower container is more likely to come into contact with the bottom of the upper container during its ascent and be cooled, and eventually condense into liquid at the bottom of the upper container and drip back into the lower container, resulting in poor drying effect of the pigment in the lower container. Utility Model Content

[0005] This invention provides a pigment drying device that ensures that the drying gas moves along the flow path in the chamber and quickly carries away the water vapor evaporated from the pigment, reducing the possibility of water vapor condensing in the chamber and falling back into the pigment, thus improving the drying effect of the pigment drying device on pigments placed in multi-layer storage containers.

[0006] This utility model is achieved through the following technical solution:

[0007] A pigment drying device includes: a housing with an inner cavity for drying pigments; a storage section disposed in the inner cavity, comprising several sets of vertically arranged storage components, each set of storage components for holding the pigments to be dried, the top of each storage component having a drying opening to allow moisture in the pigments to escape; a guide section disposed in the inner cavity, comprising several guide blocks disposed on at least one side of each storage component; a blower section comprising at least one blower opening on the side of the inner cavity for outputting drying gas into the inner cavity; and an exhaust section comprising an exhaust port disposed at the top of the inner cavity; wherein the guide blocks and the storage components constitute a guide channel for accommodating the flow of the drying gas, the drying gas flowing in the guide channel passing sequentially from the bottom of the inner cavity through the drying openings of the several sets of storage components, and finally being discharged out of the housing through the exhaust port.

[0008] As a further improvement of this utility model, the blower includes a guide section disposed on the side wall of the inner cavity, and the drying gas is guided by the guide section and enters the guide channel, where it impacts and contacts the storage component at the top of the guide channel.

[0009] As a further improvement of this utility model, a heat-conducting plate is provided at the bottom of the storage component, the top surface of the heat-conducting plate is used to contact the pigment to be dried, and the bottom surface is placed on top of the guide channel.

[0010] As a further improvement of this utility model, it also includes a lifting part, which includes at least one set of drive kits and several sets of mounting kits disposed on the drive kits, wherein the drive kits are used to lift the mounting kits and the mounting kits are used to install the storage component.

[0011] As a further improvement of this utility model, the drive kit includes a drive collar, pulleys disposed at the top and bottom of the inner ring of the drive collar, and a drive device for driving the pulleys to rotate, wherein at least one pulley is a drive wheel and is connected to the drive device.

[0012] As a further improvement of this utility model, the housing includes a shell and an opening and closing door disposed on the shell, wherein the shell is provided with a lifting control kit, the lifting control kit at least receives lifting commands and outputs start and stop commands to the drive device.

[0013] As a further improvement of this utility model, the installation kit includes a support member and a limiting member. A limiting end is formed on one end of the limiting member away from the drive kit. The limiting surface on the limiting end is in contact with the inner sidewall of the storage component. The supporting surface of the support member is in contact with the bottom surface of the storage component.

[0014] As a further improvement of this utility model, a guide surface structure is formed on the end of the support member away from the drive assembly.

[0015] As a further improvement of this utility model, the blower section includes an air supply pipe, a heating kit, and a blower kit, wherein the output port of the blower kit is connected to the air inlet of the heating kit, and the air outlet of the heating kit is connected to the blower outlet through the air supply pipe.

[0016] As a further improvement of this utility model, an observation window is provided on the box body.

[0017] The beneficial effects of this utility model include:

[0018] (1) The storage components stacked in layers and the guide blocks set on their sides together form a guide channel for the drying gas, so that the drying gas entering the inner cavity can flow from the bottom through all the drying openings on the storage components in sequence. During the flow of the drying gas, heat is provided to the storage components and the pigments therein to drive the moisture in the pigments to evaporate. On the other hand, the water vapor evaporated from the pigments can be quickly carried away and finally discharged outside the inner cavity, reducing the possibility of water vapor condensing in the inner cavity and falling back into the pigments.

[0019] (2) In the preferred structure, when the drying gas enters the guide channel, it will first come into contact with the bottom surface of the storage container placed above, thereby quickly transferring heat to the bottom of the storage container, so that the pigment placed in the storage container and located at the bottom can also be heated more fully, ensuring that all the pigments contained in the storage container can be fully dried.

[0020] (3) Since the drying gas flowing to the top of the inner cavity already carries a large amount of water vapor from the pigment at the bottom, its ability to carry water vapor is reduced. In the preferred structure, the lifting part can lift the storage unit and the pigment inside. This allows the pigment drying equipment to place a new storage unit containing pigment at the bottom and lift the original storage unit at the same time, so that the pigment close to the end of the drying process is always placed in the upper space of the inner cavity. Usually, the pigment can evaporate less water vapor, so the requirement for the water vapor carrying capacity of the drying gas is relatively lower. At the same time, placing it in the upper space of the inner cavity makes it easier for the user to take out the pigment that has completed the drying process. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0027] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0028] In this embodiment, the drying gas used is heated pure air. Any other gas that can achieve pigment drying can be used in this pigment drying equipment, so it does not affect the protection scope of the claims of this utility model.

[0029] Example 1:

[0030] This embodiment provides a pigment drying device, such as... Figure 2 As shown, it mainly includes a housing 1, a storage section 2, a guide section 3, a blower section 4, and an exhaust section 5.

[0031] The inner cavity 101 of the box 1 is used to carry out the drying work of the pigment to be dried, that is, to place the storage section 2 and the pigment it receives; and to contain the drying gas at a high temperature, so as to ensure that the inner cavity 101 is in a high temperature environment and force the moisture in the pigment to evaporate, thereby achieving the effect of drying the pigment.

[0032] The storage section 2, located within the inner cavity 101, includes several sets of vertically arranged storage components 201, which are used to directly hold pigments. In this embodiment, four sets of storage components 201 are stacked in the inner cavity 101, and each set of storage components 201 has a drying opening 201-1 at its top to allow moisture in the pigment to evaporate.

[0033] The blower section 4 includes at least one blower port 401 located on the side of the inner cavity 101 for outputting drying gas into the inner cavity 101. In this embodiment, a total of three blower ports 401 are provided to provide sufficient drying gas into the inner cavity 101, so as to ensure that the drying temperature and humidity in the chamber 1 meet the standards. At the same time, the newly introduced gas can also provide driving force for the original gas flow in the chamber 1, avoiding the accumulation of gas at any position in the chamber 1 and causing water vapor to condense and fall back.

[0034] The exhaust section 5 includes an air outlet 501 located at the top of the inner cavity 101 for discharging the gas after the drying process. Since the drying gas is typically a high-temperature gas, it naturally tends to rise; therefore, the location of the exhaust section 5 at the top also facilitates the rapid discharge of the gas.

[0035] The guide section 3 includes a plurality of guide blocks 301 disposed on at least one side of the storage member 201. The guide blocks 301 and the storage member 201 together constitute a guide channel 6 for accommodating and restricting the flow of drying gas. In this embodiment, as... Figure 2 As shown, only the bottommost storage unit 201 has guide blocks 301 on both sides, while the other storage units 201 have guide blocks 301 on only one side. Except for the bottommost storage unit 201, the guide blocks 301 on the sides of adjacent storage units 201 are not on the same side. Figure 2 Taking the placement orientation as an example, the second storage unit 201 from bottom to top has a guide block 301 on its left side, while the third storage unit 201 only has a guide block 301 on its right side. This allows the drying gas to rise and flow from the storage unit 201 away from the guide block 301, reaching the area above the current storage unit 201 and finally flowing through the drying opening 201-1 through the guide channel 6, carrying away the water vapor generated in the pigment. In this structure, the guide channel 6 formed by the guide block 301 and the storage unit 201 ensures that the drying gas can flow smoothly without accumulating in corners and causing water vapor condensation. At the same time, it forces the drying gas to flow through the drying openings 201-1 of all storage units 201 in sequence, carrying away all the water vapor, and finally discharging the water vapor outside the inner cavity 101, thereby achieving the drying effect on the pigment in the box 1.

[0036] Preferably, such as Figure 2As shown, the blower section 4 includes a guide section 402 disposed on the side wall of the inner cavity 101. Drying gas is guided by the guide section 402 and enters the guide channel 6, where it impacts and contacts the storage unit 201 at the top. During this flow, the drying gas in the guide channel 6 can both carry away the water vapor produced in the lower storage unit 201 and transfer heat to the upper storage unit 201 to heat the pigment within, forcing the moisture to turn into water vapor for subsequent removal. This structure further improves the drying efficiency of the pigment drying equipment and reduces the possibility that pigments placed at the bottom of the storage unit 201 will be difficult to dry.

[0037] Preferably, such as Figure 4 As shown, a heat-conducting plate 201-2 is provided at the bottom of the storage unit 201. The top surface of the heat-conducting plate 201-2 is used to contact the pigment to be dried, and the bottom surface is placed on top of the guide channel 6. The heat-conducting plate 201-2 can accelerate the transfer of heat provided by the drying gas to dry the pigment in the storage unit 201 as quickly as possible.

[0038] Preferably, such as Figure 1 As shown, the blower unit 4 includes an air supply pipe 403, a heating kit 404, and a blower kit 405. The output port of the blower kit 405 is connected to the air inlet of the heating kit 404 so that clean air can be input into the heating kit 404 for heating. The air outlet of the heating kit 404 is connected to the blower port 401 through the air supply pipe 403, so that the blower kit 405 can also provide driving force to transport the heated drying gas into the inner cavity 101.

[0039] Preferably, such as Figure 1 As shown, an observation window 8 is provided on the box 1 so that the user can observe the drying status of the pigment in the box 1, avoiding the situation where the pigment drying effect is poor due to frequent opening of the box 1.

[0040] Example 2:

[0041] The difference between the pigment drying device provided in this embodiment and that in Embodiment 1 is that this embodiment further includes a lifting unit 7. The lifting unit 7 includes at least one set of drive components 701 and several sets of mounting components 702 disposed on the drive components 701. The drive components 701 are used to lift the mounting components 702, and the mounting components 702 are used to mount the storage component 201. In this embodiment, to ensure the secure mounting of the storage component 201, as follows... Figure 2 As shown, two sets of vertically mounted drive kits 701 are used, and eight sets of mounting kits 702 are provided on each set of drive kits 701. Figure 2Taking the display angle as an example, two sets of installation kits 702 at the same height jointly install and fix a set of storage components 201 to ensure that the installation is stable and in a horizontal state, and to prevent the paint inside the storage components 201 from spilling during the lifting process.

[0042] In this structure, after the pigment drying process in the top storage unit 201 is complete, the user can release the mounting kit 702 from the storage unit 201, remove the storage unit 201 and the pigment inside, and then lift all the remaining storage units 201 using the drive kit 701 until the bottom storage unit 201 is vacated. The user can then install the newest storage unit 201 containing the pigment to be dried at the bottom and begin the drying process. Therefore, during the use of the pigment drying equipment, the moisture content of the pigment in each storage unit 201 should gradually decrease from bottom to top, a distribution that adapts to the characteristics of the drying gas in the pigment drying equipment.

[0043] Specifically, in this pigment drying equipment, the drying gas needs to flow sequentially from the bottom of the inner cavity 101 through the drying openings 201-1 of all storage components 201, carrying away the water vapor it produces. Therefore, the drying gas flowing to the top of the inner cavity 101 usually already carries a large amount of water vapor evaporated from the pigment at the bottom, thus reducing its water vapor carrying capacity. In other words, the water vapor carrying capacity of the drying gas in the chamber 1 decreases from bottom to top. The pigment placed in the space above the inner cavity 101, nearing the end of the drying process, produces less water vapor, thus requiring a lower water vapor carrying capacity from the drying gas. Conversely, the pigment at the bottom of the inner cavity 101 requires a relatively higher water vapor carrying capacity from the drying gas. Therefore, the distribution of the drying gas and the pigment can be matched to each other, maximizing the utilization of the drying gas and improving the drying efficiency of the pigment.

[0044] Preferably, such as Figures 3-4 As shown, the drive assembly 701 includes a drive collar 701-1, pulleys 701-2 disposed at the top and bottom of the inner ring of the drive collar 701-1, and a drive device 701-3 for driving the pulleys 701-2 to rotate. At least one pulley 701-2 is a driving wheel and is connected to the drive device 701-3. In this embodiment, the pulley 701-2 at the top of the two sets of drive assemblies 701 is the driving wheel, and the pulley 701-2 at the bottom is the driven wheel.

[0045] Preferably, such as Figure 1As shown, the housing 1 includes a shell 102 and an opening / closing door 103 disposed on the shell 102. A lifting control kit 104 is provided on the shell 102. The lifting control kit 104 receives lifting commands and outputs start / stop commands to the drive device 701-3. This structure ensures that when the opening / closing door 103 is open, the user can easily adjust the height of other storage items 201 via the lifting control kit 104, enabling quick and convenient retrieval and placement of the storage items 201.

[0046] Preferably, such as Figures 3-4 As shown, the mounting kit 702 includes a support member 702-1 and a limiting member 702-2. A limiting end 702-2-1 is formed on the limiting member 702-2 at one end away from the drive kit 701. The limiting surface 702-2-1a on the limiting end 702-2-1 fits against the inner wall of the storage member 201, and the supporting surface 702-1a of the support member 702-1 fits against the bottom surface of the storage member 201. This structure allows the storage member 201 to be engaged and fixed using the limiting surface 702-2-1a and the supporting surface 702-1a. This structure also facilitates the establishment and disengagement of the fixed installation relationship. In this embodiment, the drive collar 701-1 is composed of a chain, so rigid components such as the support member 702-1 and the limiting member 702-2 can be fixedly installed on the chain links. The fixed installation method can be a conventional connection method such as welding. The usage process of the installation kit 702 is as follows: Figure 3 As shown, the user can first lift the end of the storage piece 201 away from the mounting kit 702, then force the storage piece 201 closer to the mounting kit 702 and first insert the limiting block into the internal space of the storage piece 201; subsequently, the user can press down the end of the storage piece 201 away from the mounting kit 702, as shown. Figure 4 As shown, the supporting surface 702-1a is brought into contact with the bottom surface of the storage component 201. At the same time, the limiting surface 702-2-1a is also brought into contact with the inner wall of the storage component 201, thus achieving the installation and fixing effect of the mounting kit 702 on the storage component 201. To release the installation and fixing relationship, simply reverse the above operation.

[0047] Preferably, such as Figures 3-4 As shown, a guide surface structure 702-1b is formed on the end of the support 702-1 away from the drive kit 701. When the user lifts the end of the storage piece 201 away from the mounting kit 702 and forces the storage piece 201 closer to the mounting kit 702, the guide surface structure 702-1b helps guide the edges of the storage piece 201 to penetrate into the support 702-1 and be placed on the support surface 702-1a, making the installation and disassembly of the storage piece 201 smoother.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
