Description

Technical Field

[0001] This application relates to the field of food processing technology, and in particular to a drying apparatus. Background Technology

[0002] In industrial pressing processes, filter cloth is typically used to wrap the raw material. After the raw material is wrapped in the filter cloth, it is pressed by the press, resulting in a dry residue. The filter cloth is then separated from the residue. The filter cloth after separating the residue needs to be cleaned, folded, and stored for future use.

[0003] In traditional technology, after the filter cloth is cleaned, most of the moisture is removed through an absorption process. Then the filter cloth is folded and stored. However, the filter cloth is still relatively damp after absorbing water, which can easily breed bacteria or even mold when folded and stored. The filter cloth needs to be cleaned a second time before reuse, which reduces processing efficiency and hygiene level. Utility Model Content

[0004] Therefore, it is necessary to provide a drying device that can store filter cloths more cleanly, hygienically, and for a longer period of time.

[0005] One embodiment of this application provides a drying apparatus.

[0006] A drying device includes a drying chamber, a blower, a guide roller, a fan, and a heating element. The drying chamber has a drying cavity and a fabric inlet and an outlet communicating with the drying cavity. The blower is disposed inside the drying chamber and has an air inlet and an air outlet on its surface. The guide roller is connected to the drying chamber to guide the movement of the filter cloth. The fan is connected to the heating element through a connecting duct. The heating element is installed in the drying chamber and located at the air inlet.

[0007] In some embodiments, the surface of the bellows is provided with a plurality of air outlets.

[0008] In some embodiments, the air outlets are respectively provided on two opposite surfaces of the bellows.

[0009] In some embodiments, the plurality of air outlets are arranged in an array.

[0010] In some embodiments, the air inlet is provided at one end of the bellows.

[0011] In some embodiments, the bellows is flat and extends vertically, with the air inlet located above the bellows.

[0012] In some embodiments, there are multiple air boxes, which are distributed along the same direction and spaced apart. Drying channels for filter cloth to pass through are formed between adjacent air boxes and between the outermost air box and the inner wall of the drying chamber. Guide rollers are provided at the opening of each drying channel to change the direction of movement of the filter cloth.

[0013] In some embodiments, the drying chamber further includes an air inlet channel, which is connected to the connecting air duct, and a plurality of air inlets are respectively connected to the air inlet channel.

[0014] In some embodiments, the drying chamber further includes an exhaust duct, through which the drying cavity communicates with the fan.

[0015] In some embodiments, the drying chamber is further provided with a fresh air inlet that communicates with the drying cavity.

[0016] In some embodiments, the drying device further includes an exhaust pipe and an air valve, the exhaust pipe being connected to the connecting duct, and the exhaust pipe being equipped with an air valve.

[0017] In some embodiments, the heating element includes a steam heater.

[0018] In some embodiments, the fan includes a centrifugal fan.

[0019] The aforementioned drying device, by providing multiple air outlets on the surface of the air box, can dry the cleaned filter cloth. The high-temperature gas emitted from the multiple air outlets can accelerate the drying of the filter cloth. The drying device of this application can store the cleaned filter cloth more cleanly and hygienically, improving processing efficiency and hygiene level.

[0020] Compared with traditional technologies, the drying apparatus of this application has the following advantages:

[0021] (1) By setting multiple air outlets on the surface of the air box, the cleaned filter cloth can be dried quickly.

[0022] (2) Multiple air boxes and multiple sets of guide rollers are set up, which can realize the filter cloth to move back and forth between multiple air boxes, increase the time the filter cloth stays in the dryer, and have a long enough contact time with hot air, thus improving the drying effect of the filter cloth.

[0023] (3) Multiple air outlets are provided. Hot air comes out from these multiple air outlets, penetrates the filter cloth attached to the air box, and dries the filter cloth. The filter cloth has a large contact area with the air box, and multiple positions of the filter cloth are dried at the same time through multiple air outlets, so that the filter cloth is fully in contact with the hot air, which greatly improves the drying effect.

[0024] (4) The circulating air mode consisting of a fan, connecting pipes and heating components is adopted. The hot air that has penetrated the filter cloth will re-enter the fan, saving resources and reducing drying costs.

[0025] (5) Some hot air is discharged through the air valve and exhaust pipe, and fresh air can enter through the fresh air inlet. The opening of both the fresh air inlet and the exhaust pipe can be adjusted by the air valve, which is very energy-saving. Attached Figure Description

[0038] This application provides a drying apparatus 10 to solve at least one of the following problems in the conventional technology: after the filter cloth 20 is washed, moisture is removed through a water absorption process, which easily leads to bacterial growth or even mold when folded and stored. Furthermore, the filter cloth 20 needs to be washed again before reuse, thus reducing processing efficiency and hygiene standards. The drying apparatus 10 will be described below with reference to the accompanying drawings.

[0039] The drying apparatus 10 provided in this application embodiment is exemplary; please refer to [link to example]. Figure 1 As shown, Figure 1 This is a front view schematic diagram of the drying apparatus 10 provided in an embodiment of this application. The drying apparatus 10 of this application can be used to dry various washed materials, such as fabrics. For example, the drying apparatus 10 of this application can be used to dry the washed filter cloth 20, thereby improving the storage time and hygiene level of the filter cloth 20.

[0040] To more clearly illustrate the structure of the drying device 10, the drying device 10 will be described below in conjunction with the accompanying drawings.

[0041] For example, please refer to Figure 1 As shown, a drying device 10 includes a drying chamber 100, a blower 200, a guide roller 300, a fan 400, and a heating element 500. The drying chamber 100 has a drying cavity 110 and a fabric inlet 111 and an outlet 112 communicating with the drying cavity 110. Filter cloth 20 enters the drying cavity 110 through the fabric inlet 111 and exits through the fabric outlet 112 after drying. See also... Figure 2 As shown, Figure 2 This is a side cross-sectional view of the drying apparatus 10 according to one embodiment of this application. An air box 200 is disposed inside the drying chamber 100. The air box 200 has an air inlet and an air outlet 210 located on its surface. Guide rollers are connected to the drying chamber 100 to guide the movement and direction change of the filter cloth 20. A fan 400 is connected to a heating element 500 via a connecting duct 410. The heating element 500 is mounted in the drying chamber 100 and located at the air inlet.

[0042] The aforementioned drying device 10, by providing multiple air outlets 210 on the surface of the air box 200, can dry the cleaned filter cloth 20. The high-temperature gas ejected from the multiple air outlets 210 can accelerate the drying of the filter cloth 20. The drying device 10 of this application can store the cleaned filter cloth 20 more cleanly and hygienically, improving processing efficiency and hygiene level.

[0043] In some implementations, see Figure 3 and Figure 4 As shown, Figure 3 This is a top view schematic diagram of the air box 200 of the drying apparatus 10 according to one embodiment of this application. Figure 4This is a schematic diagram of the surface of the air box 200 of the drying apparatus 10 according to an embodiment of this application. The surface of the air box 200 is provided with a plurality of air outlet holes 210.

[0044] In some embodiments, multiple air outlets 210 are arranged in an array.

[0045] In some embodiments, the diameter of the air outlet 210 is set as needed. For example, the diameter of the air outlet 210 is 0.5cm to 5cm.

[0046] In some embodiments, an air inlet is provided at one end of the bellows 200. Air outlets 210 are provided on both surfaces of the bellows 200.

[0047] In some implementations, see Figure 2 , Figure 3 As shown, the bellows 200 is flat and extends vertically, with the air inlet located above the bellows 200.

[0048] In some embodiments, there are multiple bellows 200. The multiple bellows 200 are distributed along the same direction and spaced apart; alternatively, see [link to other embodiments]. Figure 2 As shown, when the air box 200 extends vertically, multiple air boxes 200 are distributed horizontally and spaced apart. Drying channels for the filter cloth 20 are formed between adjacent air boxes 200 and between the outermost air box 200 and the inner wall of the drying chamber 110. Guide rollers 300 are provided at the openings of each drying channel to change the direction of movement of the filter cloth 20. After passing one of the guide rollers 300, the filter cloth 20 enters the corresponding drying channel through one end opening and exits from the other end opening. After being turned by the guide roller 300 at that end opening, it enters the corresponding drying channel again. This process is repeated to complete a meandering path within multiple drying channels. This meandering path of the filter cloth 20 within multiple drying channels increases the drying time and improves drying efficiency.

[0049] In some embodiments, the spacing between adjacent air boxes 200 is 1cm to 100cm. Optionally, the spacing between adjacent air boxes 200 is 5cm to 50cm. Optionally, the spacing between adjacent air boxes 200 is 10cm to 30cm. The spacing between adjacent air boxes 200 should not be too large or too small. When the spacing between adjacent air boxes 200 is too large, the distance between the air outlet 210 and the filter cloth 20 is large, resulting in poor drying effect. Preferably, the gap between adjacent air boxes 200 is approximately the same as the diameter of the guide roller 300. With this arrangement, after the filter cloth is turned by the guide roller 300, it moves straight up and down in the vertical direction, which can fit well with the surface of the air box 200, resulting in good drying effect.

[0050] In some embodiments, the drying chamber 100 further includes an air inlet channel 120. The air inlet channel 120 communicates with the connecting air duct 410. Multiple air inlets are respectively connected to the air inlet channel 120.

[0051] In some of these implementations, please refer to Figure 2 As shown, the drying chamber 100 also includes an exhaust duct 130. The drying chamber 110 is connected to the fan 400 through the exhaust duct 130.

[0052] In some of these implementations, please refer to Figure 2 As shown, the drying chamber 100 is also provided with a fresh air inlet 140 communicating with the drying chamber. The fresh air inlet 140 can supplement fresh air as needed. In this application, there is a gap between the air box 200 and the inner wall of the drying chamber. Therefore, the fresh air entering through the fresh air inlet 140 can enter the gap between the air box 200 and the inner wall of the drying chamber, as well as the gap between adjacent air boxes 200, and can also directly enter the exhaust duct 130.

[0053] In some of these implementations, please refer again. Figure 1 As shown, the drying device 10 also includes an exhaust duct 600 and an air valve 700. The exhaust duct 600 is connected to the connecting duct 410, and the air valve 700 is installed on the exhaust duct 600. The exhaust duct 600 and the air valve 700 work together to output a portion of the air that has been circulated several times, and to replenish fresh air through the fresh air inlet 140. The air valve 700 can adjust the opening degree of the exhaust duct 600.

[0054] In some embodiments, the heating element 500 includes a steam heater. A steam heater is a device that uses the heat of steam to heat another fluid (liquid or gas), typically used in industrial and commercial applications to provide space heating, process heating, or hot water. The design of a steam heater can vary depending on the application and the medium to be heated. The working principle of a steam heater: The core of a steam heater is the transfer of heat from the steam to the medium to be heated through heat exchange. When high-pressure steam enters the heater, it comes into contact with the heat exchange surface, releasing latent heat and condensing into water in the process. This heat transfer causes the temperature of the heated medium to rise.

[0055] In some embodiments, the steam heaters include one or more of the following types: (1) Shell-and-tube heat exchangers: steam passes through a series of pipes (called tube bundles), while the medium to be heated flows around the pipes. (2) Plate heat exchangers: heat exchange is carried out using a series of parallel metal plates with narrow spaces between each plate for the two media to flow separately. (3) Air heaters: steam heaters specifically designed for heating air, commonly used in industrial drying processes or HVAC systems in buildings.

[0056] In some embodiments, the fan 400 includes a centrifugal fan 400.

[0057] In some of these implementations, please refer to Figure 2 As shown, in terms of positioning, the air inlet duct 120 is located above the drying chamber 100, and the fresh air inlet 140 is located at the lower part of the drying chamber 100. The exhaust duct 130 is located vertically between the air inlet duct 120 and the fresh air inlet 140. Since the air box 200 extends vertically, one end of the drying duct opening is located at the upper part of the drying chamber 110, and the other end is located at the lower part of the drying chamber 110. Several guide rollers 300 are respectively arranged at the upper and lower parts of the drying chamber 110.

[0058] Please see Figure 2 As shown, in this application, the filter cloth 20 enters the drying chamber 110 of the drying box 100 through the inlet 111, and under the guidance of the guide rollers 300, it advances sequentially along each drying channel and exits from the outlet 112. The airflow direction follows... Figure 2 As indicated by the arrow, fresh air is drawn in through the fresh air inlet 140 and enters the fan 400. The air exiting the fan 400 is heated by the heating element 500 and then enters the air inlet channel 120. The hot air in the air inlet channel 120 enters each air box 200 through the air inlet and is ejected through the air outlet 210, drying the filter cloth 20. The hot air then enters the fan 400 through the exhaust channel 130 for recirculation.

[0059] Compared with traditional technologies, the drying apparatus 10 of this application has the following advantages:

[0060] (1) By setting multiple air outlets 210 on the surface of the air box 200, the cleaned filter cloth 20 can be dried quickly.

[0061] (2) Multiple air boxes 200 and multiple sets of guide rollers 300 are set up, which can realize the filter cloth 20 to move back and forth between multiple air boxes 200, increase the residence time of the filter cloth 20 in the dryer, and have a long enough contact time with hot air, thus improving the drying effect of the filter cloth 20.

[0062] (3) Multiple air outlets 210 are provided. Hot air comes out from these multiple air outlets 210, penetrates the filter cloth 20 attached to the air box 200, and dries the filter cloth 20. The filter cloth 20 has a large contact area with the air box 200, and multiple positions of the filter cloth 20 are dried at the same time through multiple air outlets 210, so that the filter cloth 20 is in full contact with the hot air, which greatly improves the drying effect.

[0063] (4) The circulating air mode consisting of fan 400, connecting pipe and heating component 500 is adopted. The hot air that has penetrated the filter cloth 20 will re-enter the fan 400, saving resources and reducing drying costs.

[0064] (5) Some hot air is discharged through the air valve 700 and the exhaust pipe 600, and fresh air can enter through the fresh air inlet. The opening of the fresh air inlet 140 and the exhaust pipe 600 can be adjusted by the air valve 700, which is very energy-saving.

[0065] In the above embodiments, the descriptions of each embodiment have their own emphasis. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0066] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative of several implementations of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
