Description

Technical Field

[0001] This utility model relates to the field of dryer impregnation technology, specifically to a spray device for a double-cone drum impregnation dryer. Background Technology

[0002] The double cone drum impregnation dryer, as an integrated material handling device, plays a crucial role in key processes in industries such as chemical, pharmaceutical, and food processing. The spray system of the double cone drum impregnation dryer achieves the impregnation effect by spraying the material inside the double cone drum through perforations in the spray pipes. However, in practical applications, the double cone drum impregnation dryer also faces some technical challenges, particularly regarding the uniformity of spraying.

[0003] Existing double-cone drum impregnation dryers typically use a horizontal conveying pipe with nozzles to spray the impregnation solution onto the material inside the double-cone drum, thus impregnating the material. However, to ensure thorough impregnation and improve drying efficiency, different volumes are usually filled into the double-cone drum depending on the material. Therefore, the existing conveying pipe and multiple nozzles are insufficient for uniform impregnation of materials with varying volumes.

[0004] To address this issue, many spray systems are designed to adjust the number of nozzles based on the required volume of different materials. Adjusting the number of nozzles to accommodate varying material volumes allows for impregnation of materials of different sizes. However, the nozzle spacing is difficult to precisely control based on changes in material volume. For example, increasing the number of nozzles too much or widening the spacing may cause the nozzles to spray onto the inner wall of the double-cone drum, resulting in residue buildup, wasting impregnation solution, and failing to completely cover the material. Conversely, reducing the number of nozzles too little or narrowing the spacing may leave material on both sides unsprayed, thus reducing the impregnation effect. Utility Model Content

[0005] In view of this, the present invention provides a spraying device for a double cone drum impregnation dryer. Through the cooperation of the first spraying pipe, the second spraying pipe and the angle adjustment mechanism, the opening of the second spraying pipe can be adjusted according to the volume of the material in the double cone drum impregnation dryer, so that the impregnation liquid can evenly cover the surface of the material, reduce waste and improve the impregnation effect.

[0006] To solve the above-mentioned technical problems, this utility model provides a spraying device for a double cone drum impregnation dryer, including a water supply pipe. The water supply pipe is connected to the outlet of a pump installed on the double cone drum impregnation dryer via a flange. A connecting pipe is provided at the end of the water supply pipe. The connecting pipe is detachably connected to the end of the water supply pipe. A first spraying pipe is connected to the end of the connecting pipe. The first spraying pipe and the connecting pipe are arranged in a T-shape, so that the first spraying pipe can be set parallel to the upper surface of the material placed in the double cone drum impregnation dryer. A second spraying pipe is provided at both ends of the first spraying pipe via an angle adjustment mechanism. The angle adjustment mechanism can be used to connect the second spraying pipe to the first spraying pipe and to allow the second spraying pipe to be angled.

[0007] Two sets of angle adjustment mechanisms are used to drive the two second spray pipes to bend downwards as a whole, thereby adjusting the spray opening of the two second spray pipes. This allows the spray opening of the two second spray pipes to be adjusted according to the change in the material volume, so that the material can be evenly impregnated, further preventing wall adhesion and improving the impregnation effect.

[0008] The angle adjustment mechanism includes an angle adjuster located between the first spray pipe and the second spray pipe, thereby connecting the first spray pipe and the second spray pipe. The angle adjuster is used to adjust the spray opening of the second spray pipe, so that the second spray pipe can be quickly adjusted to a suitable angle as needed.

[0009] The first spray pipe and the second spray pipe are provided with a connecting pipe. The connecting pipe allows the solution to flow between the first spray pipe and the second spray pipe even when the angle of the second spray pipe is adjusted. The connecting pipe allows the solution entering the first spray pipe to flow into the second spray pipe and be sprayed out through multiple nozzles on the second spray pipe.

[0010] A first feeding pipe is connected to the outer walls of both ends of the first spray pipe. The first feeding pipe is fixedly connected to the outer walls of both ends of the first spray pipe. A second feeding pipe is connected to the outer walls of both second spray pipes. The second feeding pipe is fixedly connected to the outer walls of the second spray pipes. The first feeding pipe and the corresponding second feeding pipe are connected through a connecting pipe. Both ends of the connecting pipe can be detachably connected to the ends of the first feeding pipe and the corresponding second feeding pipe.

[0011] The angle adjuster is set as a universal ball joint, which allows the second spray pipe to be adjusted to a suitable position at will. It can then be fixed to adjust the second spray pipe to a suitable spray angle. This allows the spray angle of the second spray pipe to be adjusted according to the amount of material in the double cone drum impregnation dryer. This can prevent the material from sticking to the inner wall of the dryer due to excessive spray opening, and also prevent uneven impregnation due to insufficient opening.

[0012] The ball joint's head end and rod end are detachably connected to the ends of the first and second spray pipes, respectively. The ball joint's head end can be connected to either the end of the first or the end of the second spray pipe, and vice versa.

[0013] Both ends of the universal ball joint are connected to the ends of the first and second spray pipes via flanges. Connecting via flanges allows for quick disassembly and assembly of the second spray pipe when maintenance or replacement is required.

[0014] The connecting pipe is made into a corrugated pipe. Making it into a corrugated pipe can reduce costs and also allow the solution passing through the first spray pipe to be transported into the second spray pipe even when the second spray pipe is bent downwards.

[0015] Both the first and second feeding pipes are connected to both ends of the connecting pipe via clamps, which allows the connecting pipe to be quickly disassembled and reassembled when maintenance or replacement is required.

[0016] The water supply pipeline and the connecting pipe are connected by flanges, which makes it easy to quickly disassemble and assemble the connecting pipe and its components when maintenance or replacement is required.

[0017] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0018] 1. Improved impregnation uniformity: Through the cooperation of the first spray pipe, the second spray pipe and the angle adjustment mechanism, the spray opening of the second spray pipe can be flexibly adjusted. The spray coverage range can be precisely controlled according to the volume and stacking height of the material in the double cone drum impregnation dryer, avoiding the problems of wall adhesion and incomplete coverage caused by traditional spraying. The impregnation liquid can evenly cover the surface of the material, reducing waste and significantly improving the impregnation effect. It is especially suitable for the process requirements of different batches and different filling volumes.

[0019] 2. Improved equipment reliability: The corrugated pipe is used as the connecting pipe, which can adaptively expand and contract when the angle of the second spray pipe is adjusted, ensuring a continuous and stable connection of the impregnation liquid between the first spray pipe and the second spray pipe.

[0020] 3. Improved sealing and ease of maintenance: The fatigue resistance of the bellows avoids damage caused by frequent bending. Combined with quick-release clamps, it can ensure both sealing performance and ease of maintenance. The universal ball joint connected by flanges further improves the stability and vibration resistance of the structure.

[0021] 4. Increased stability: Connecting the connecting pipe through the first and second feeding pipes can prevent the connecting pipe from being clamped at the ball head of the universal ball joint when it is bent and deformed, and further prevent the connection pipe from being clamped by the universal ball joint, which would cause the impregnation liquid to flow poorly.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0028] A spray device for a double-cone drum impregnation dryer, such as Figure 1 As shown: It includes a water supply pipe 101, which is connected to the outlet of the pump installed on the double cone drum impregnation dryer via a flange. This allows the liquid storage tank on the spray system of the double cone drum dryer to be pumped to the water supply pipe 101. The impregnation liquid can then be transported through the water supply pipe 101 to the first spray pipe 103 and the second spray pipe 104 via the connecting pipe 102. The first spray pipe 103 and the second spray pipe 104 spray the impregnation liquid onto the material through their nozzles to impregnate the material. The end of the water supply pipe 101 is provided with a connecting pipe 102, which connects and supports the various components below it. The connecting pipe 102 can also achieve a directional change when connecting to the first spray pipe 103.

[0029] The first spray pipe 103 and the connecting pipe 102 are arranged in a T-shape, so that the first spray pipe 103 can be set parallel to the upper surface of the material placed in the double cone drum impregnation dryer, thereby further improving its spraying effect and making the impregnation of the material more uniform.

[0030] like Figure 1 ,2 As shown: Both ends of the first spray pipe 103 are equipped with second spray pipes 104 via angle adjustment mechanisms. The second spray pipes 104 can be connected to the first spray pipe 103 via the angle adjustment mechanisms, and the angle of the second spray pipes 104 can be adjusted. This allows the operator to adjust the angle of the two second spray pipes 104 according to the amount of material in the vessel (i.e., adjust the second spray pipes 104 to a suitable position). Therefore, by adjusting the angle of the two second spray pipes 104, the first spray pipe 103 can work with the adjusted two second spray pipes 104 to form a suitable spray angle for the material in the vessel, which can further improve the impregnation effect of the material in the vessel and avoid the impregnation liquid from sticking to the inner wall of the vessel, thus preventing waste.

[0031] like Figure 2 As shown: Two sets of angle adjustment mechanisms are used to drive the two second spray pipes 104 to bend downwards as a whole, thereby adjusting the spray opening of the two second spray pipes 104. The opening of the two second spray pipes 104 can be quickly adjusted according to the change in the volume of material in the vessel. As the second spray pipes 104 are bent downwards, the angle between the second spray pipe 104 and the first spray pipe 103 will gradually decrease, and conversely, the angle between the second spray pipe 104 and the first spray pipe 103 will gradually increase. Therefore, the operator can adjust the two second spray pipes 104 by adjusting the angle adjustment mechanism according to the amount of material in the vessel, so as to ensure that the material is evenly impregnated and to avoid the impregnation liquid sticking to the wall in the vessel, thereby improving the impregnation effect.

[0032] The two sets of angle adjustment mechanisms have the same structure, as shown in the figure: the angle adjustment mechanism includes an angle adjuster 105. The angle adjuster 105 can be used to quickly bend the second spray pipe 104, so that the second spray pipe 104 can quickly adjust the angle between itself and the first spray pipe 103 according to the volume of the material.

[0033] Angle adjuster 105 is located between the first spray pipe 103 and the second spray pipe 104. It can be used to connect the first spray pipe 103 and the second spray pipe 104, and the spray opening of the second spray pipe 104 can be adjusted by angle adjuster 105, so that the second spray pipe 104 can be quickly adjusted to a suitable angle for use according to the volume of material in the vessel.

[0034] like Figure 1 , 2As shown: The angle adjuster 105 is set as a universal ball joint. The universal ball joint is a self-locking universal ball joint, so the position of the second spray pipe 104 can be adjusted by rotating the ball end or the rod end of the universal ball joint, which improves the adjustment speed of the second spray pipe 104. After the second spray pipe 104 is adjusted to a suitable position, it can be locked, which can prevent the material from colliding with the second spray pipe 104 or the vibration caused by the continuous flow of the impregnation liquid through the second spray pipe 104 and its nozzle, thus preventing the second spray pipe 104 from being displaced, and further improving the stability of the second spray pipe 104 during operation.

[0035] The ball head end and the rod end of the universal ball joint are detachably connected to the ends of the first spray pipe 103 and the second spray pipe 104, respectively. That is, the ball head end of the universal ball joint can be connected to the end of the corresponding first spray pipe 103 or the end of the corresponding second spray pipe 104, and vice versa. In summary, the two ends of the universal ball joint can be installed arbitrarily at the ends of the corresponding first spray pipe 103 or the second spray pipe 104.

[0036] Both ends of the universal ball joint are connected to the ends of the first spray pipe 103 and the second spray pipe 104 via flanges. The flange connection allows for quick disassembly and assembly of the second spray pipe 104 when maintenance or replacement is required. Both ends of the universal ball joint can also be fixedly connected to the ends of the first spray pipe 103 and the second spray pipe 104, thereby further improving the stability of the overall structure and preventing it from falling off due to various factors inside the vessel during use (such as continuous collision between the material and the universal ball joint, vacuuming inside the vessel, etc.).

[0037] like Figure 2 , 3 As shown: A connecting pipe 203 is provided on the first spray pipe 103 and the second spray pipe 104. The connecting pipe 203 allows the impregnation liquid to flow between the first spray pipe 103 and the second spray pipe 104 even when the angle of the second spray pipe 104 is adjusted. That is, when the impregnation liquid is continuously injected into the first spray pipe 103 through the connecting pipe 102, the impregnation liquid will flow from the first spray pipe 103 into the second spray pipe 104 through the connecting pipe 203, so that the nozzles on the second spray pipe 104 can continuously spray the impregnation liquid onto the material. Therefore, the nozzles on both the first spray pipe 103 and the second spray pipe 104 can continuously spray the impregnation liquid onto the material, so that the material is uniformly impregnated. The nozzles on the first spray pipe 103 and the second spray pipe 104 can be set as atomizing nozzles or fan-shaped nozzles, which can further improve the impregnation effect and uniformity of the material.

[0038] like Figure 2 , 3As shown: First feed pipes 201 are connected to both ends of the outer wall of the first spray pipe 103, and a second feed pipe 202 is connected to the outer wall of each of the two second spray pipes 104. The first feed pipes 201 and the second feed pipes 202 are set so that the connecting pipe 203 can be connected, and the connecting pipe 203 can maintain a certain distance from the first spray pipe 103 and the second spray pipe 104. This avoids the connecting pipe 203 from being partially clamped at the ball head end of the universal ball joint during the adjustment process, or from being clamped by the ball head when the connecting pipe 203 bends towards the universal ball joint end, which would prevent the impregnation liquid from flowing quickly. The connecting pipe 102 can also be directly fixed or detachably connected to the first spray pipe 103 and the second spray pipe 104 without the support of the first feed pipes 201 and the second feed pipes 202.

[0039] The first feeding pipe 201 and the second feeding pipe 202 are respectively fixedly connected to the first spray pipe 103 and the second spray pipe 104, which can provide a stable support structure for the connecting pipe 203 and enable the connecting pipe 203 to stably transport the impregnation liquid to the second spray pipe 104, avoiding detachment due to material collision during continuous transportation. The first feeding pipe 201 and the second feeding pipe 202 can also be connected by threaded, flanged or other connectors, so that the first feeding pipe 201 and the second feeding pipe 202 can be quickly disassembled and assembled when maintenance or replacement is required.

[0040] The first feeding pipe 201 and the second feeding pipe 202 are connected by a connecting pipe 203, so that the connecting pipe 203 can continuously transport the impregnation liquid fed into the first feeding pipe 201 to the second spray pipe 104 through the second feeding pipe 202, and then spray the impregnation liquid onto the material through the nozzle on the second spray pipe 104, so that the material can be impregnated.

[0041] Both the first feeding pipe 201 and the second feeding pipe 202 are connected to both ends of the connecting pipe 203 by clamps, which ensures that the connecting pipe 203, the first feeding pipe 201 and the second feeding pipe 202 can be sealed when the impregnation liquid passes through, and allows for quick disassembly and assembly when the connecting pipe 203 needs maintenance or replacement.

[0042] like Figure 1 , 2As shown: The connecting pipe 203 is set as a corrugated pipe. Setting it as a corrugated pipe can reduce costs, and during the downward bending of the second spray pipe 104, the impregnation liquid passing through the first spray pipe 103 can still be transported to the second spray pipe 104 through the connecting pipe 203. Furthermore, during the downward bending of the second spray pipe 104, the connecting pipe 203 can adaptively adjust due to its corrugated structure. Therefore, it can extend the service life of the connecting pipe 203 and avoid damage to the connecting pipe 203 due to excessive adjustment.

[0043] The connecting pipe 102 is detachably connected to the end of the water supply pipe 101, so that the connecting pipe 102 can be disassembled and installed on the water supply pipe 101. This facilitates disassembly and installation when maintenance or replacement of the connecting pipe 102 and its components is required. The connecting pipe 102 can be connected to the water supply pipe 101 via a flange or via threaded connectors, further facilitating subsequent maintenance and replacement.

[0044] The connecting pipe 102 and the first spray pipe 103 can be connected by threads or flanges, which allows for quick disassembly and assembly when the connecting pipe 102 needs to be replaced or maintained separately.

[0045] In use, first install the connecting pipe 102 and its lower components onto the water supply pipe 101. Then, adjust the position of the two second spray pipes 104 according to the required volume of material to be loaded (i.e., the height and degree of accumulation of the material in the vessel). When adjusting the second spray pipes 104, first loosen the locking part of the universal ball joint (i.e., the screw on the universal ball joint or other fasteners used to fix the ball head). As the universal ball joint is adjusted, the second spray pipes 104 will adjust their position accordingly. After adjusting to the appropriate position, lock the locking part of the universal ball joint for use. During the adjustment of the universal ball joint, the connecting pipe 203 will stretch or contract accordingly to achieve adaptive adjustment.

[0046] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0047] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
