Description

Technical Field

[0001] The present invention relates to the technical field of mesh belt dryers, in particular to a device and method for quickly replacing a mesh belt of a mesh belt dryer. Background Art

[0002] At present, mesh belt dryers are widely used in drying production operations and are suitable for drying a variety of materials, especially agricultural products with different particle sizes.

[0003] Due to the different particle sizes of the materials being dried, if the mesh belt aperture is too large and the material particle size is smaller than the mesh belt aperture, the material will fall directly from the mesh belt holes and cannot meet the drying requirements; if the mesh belt aperture is too small, far smaller than the shape of the material, the air volume passing through the mesh belt mesh will be reduced, reducing the drying efficiency.

[0004] In order to ensure that ordinary materials can be dried normally, general manufacturers usually install mesh belts with the smallest aperture when the mesh belt dryer leaves the factory, and the mesh belts cannot be replaced, which greatly reduces the drying efficiency when drying large-sized materials. Summary of the Invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a device and method for quickly replacing the mesh belt of a mesh belt dryer, so as to solve the problem that the mesh belt cannot be replaced, realize the rapid replacement of the mesh belt, and be able to select mesh belts of different apertures according to different materials, thereby improving the drying efficiency.

[0006] (First aspect) At least one disclosed embodiment of the present invention provides a quick mesh belt replacement device for a mesh belt dryer, the dryer comprising a dryer body having a window at one end thereof;

[0007] A belt conveyor structure is installed in the main body of the dryer, and the belt conveyor structure has a mesh belt installation positioning plate, and the mesh belt installation positioning plate has a positioning pin and a high-temperature resistant samarium cobalt magnet;

[0008] A mesh belt reel device is provided at the window position of the dryer body, and a mesh belt member is wound on the mesh belt reel device; the mesh belt member includes a mesh belt and metal positioning plates fixed at both ends thereof, the metal positioning plates are provided with positioning holes, and the metal positioning plates are also fixed with high-temperature resistant samarium cobalt magnets;

[0009] When the belt conveyor structure drives the mesh belt installation positioning plate to rotate to the window position, one end of the mesh belt is put on the positioning pin through the corresponding positioning hole, and the mesh belt installation positioning plate and the mesh belt are fixed by magnetic adsorption; when the belt conveyor structure rotates one circle, the mesh belt is wound on the belt conveyor structure, and then the positioning hole at the other end of the mesh belt is put on the positioning pin and fixed by magnetic adsorption; the mesh belt can be quickly installed and replaced very conveniently.

[0010] For example, according to the above disclosed embodiments, the belt conveyor structure is a metal mesh belt device, which can provide sufficient support for the mesh belt, facilitate the fixation of the mesh belt installation positioning plate, and has sufficiently large pores.

[0011] For example, according to the disclosed embodiment, the mesh belt mounting plate includes a positioning plate and a positioning pressure plate. The positioning plate has a positioning pin fixed with a high-temperature-resistant samarium-cobalt magnet. The positioning plate and the positioning pressure plate are clamped and fixed to the belt conveyor structure from above and below. This structure facilitates the rapid fixation of the mesh belt mounting plate.

[0012] For example, according to the above-mentioned disclosed embodiment, in the mesh belt part, the metal positioning plates arranged at both ends of the mesh belt are metal positioning plate 1 and metal positioning plate 2 respectively; positioning holes are opened on the metal positioning plate 1 and the metal positioning plate 2, and a high-temperature resistant samarium cobalt magnet 2 is fixed on the metal positioning plate 2.

[0013] For example, according to the disclosed embodiment, the mesh belt reel device includes a reel and a reel mounting shaft; one end of the reel mounting shaft is mounted on the dryer body, while the other end is free; the reel is sleeved on the reel mounting shaft, and the mesh belt is wound around the reel, which also has a crank handle. The mesh belt reel device winds up the mesh belt and adaptively releases the mesh belt via the crank handle according to the rotational speed of the belt conveyor structure.

[0014] For example, according to the above disclosed embodiment, a plurality of mounting shaft positioning plates are provided on the dryer body at different heights from top to bottom; the mounting shaft positioning plates have a plurality of slots, and the drum mounting shaft is inserted into the corresponding slots and locked and fixed by a locking pin.

[0015] For example, according to the above disclosed embodiment, the metal mesh belt device includes a metal mesh belt and a rotating shaft cylinder; baffles are fixed on both sides of the metal mesh belt, and a transmission chain is provided on the outside of the baffle, and the rotating shaft cylinder drives the entire metal mesh belt to move.

[0016] (Second aspect) At least one disclosed embodiment of the present invention provides a method for quickly replacing a mesh belt of a mesh belt dryer, comprising the following steps:

[0017] S1. Rotate the belt conveyor structure and stop when the mesh belt installation positioning plate on it approaches the window; if there is a mesh belt part on the rotating belt conveyor structure, remove it;

[0018] S2. Insert one end of the mesh belt installed on the drum into the dryer body through the window, fit the positioning hole of the metal positioning plate on this end over the positioning pin on the mesh belt installation positioning plate, and allow the high-temperature resistant samarium-cobalt magnet to adsorb the metal positioning plate;

[0019] S3. Rotate the belt conveyor structure for one circle, and tighten the high-temperature resistant polyester mesh belt through the mesh belt reel device, and attach the high-temperature resistant polyester mesh belt to the belt conveyor structure; then buckle the metal positioning plate 2 at the end of the mesh belt into the positioning pin of the positioning plate of the mesh belt installation positioning plate, and adsorb the metal positioning plate 2 onto the metal positioning plate 1 through the high-temperature resistant samarium cobalt magnet 2 bonded to the metal positioning plate 2.

[0020] The present invention has the following advantages:

[0021] (1) It can realize the replacement of the mesh belt of the mesh belt dryer, and can achieve quick and convenient replacement, thereby improving the drying effect;

[0022] Specifically, in traditional mesh belt dryers, the mesh belt on the belt conveyor structure is fixed, and the mesh of the mesh belt has been set at the factory (usually a very small mesh is selected), which is not conducive to drying and cannot be replaced;

[0023] In the present invention, a positioning pin is provided on the belt conveyor structure, and a positioning hole is opened on the mesh belt, and the two are fixed by magnetic adsorption, so that the mesh belt can be replaced and the replacement is very convenient; thus, the mesh belt with corresponding mesh size can be selected for replacement according to needs, thereby improving the drying effect;

[0024] (2) The structure is simple, and when the mesh belt is replaced, it can ensure that it fits well on the belt conveyor structure;

[0025] Specifically, when the belt conveyor structure rotates, the mesh belt reel device is controlled by a hand crank to tighten the mesh belt so that it is well attached to the belt conveyor structure.

[0026] The mesh belt reel device has a very simple structure and low cost, and is suitable for wide application. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0037] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein may be combined with each other.

[0038] In addition, the orientation or positional relationship indicated by the terms "upper" and "lower" is based on the orientation or positional relationship shown in the accompanying drawings, or is the orientation or positional relationship in which the inventive product is conventionally placed when in use, or is the orientation or positional relationship conventionally understood by those skilled in the art. Such terms are only used to facilitate the description of the present invention and simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0039] like Figures 1 to 8 As shown, this embodiment discloses a quick-change mesh belt device for a mesh belt dryer. The dryer includes a dryer body 1, one end of which has a window 103; a belt conveyor structure is installed in the dryer body 1, and the belt conveyor structure has a mesh belt mounting positioning plate 2, which has a positioning pin 206 and a high-temperature resistant samarium cobalt magnet 201; a mesh belt reel device 5 is provided at the position of the window 103 of the dryer body 1, and a mesh belt member 4 is wound on the mesh belt reel device 5; the mesh belt member 4 includes a mesh belt 403 and metal positioning plates fixed at both ends thereof, the metal positioning plates have positioning holes, and the metal positioning plates are also fixed with a high-temperature resistant samarium cobalt magnet 402;

[0040] When installation and replacement are required: the mesh belt member 4 of the corresponding mesh is wound on the mesh belt reel device 5 in advance; when a new mesh belt member 4 needs to be installed, the belt conveyor structure drives the mesh belt installation positioning plate 2 to rotate to the window 103 position, and the old mesh belt member 4 is removed; then one end of the new mesh belt member 4 is sleeved on the locating pin 206 of the mesh belt installation positioning plate 2 through the corresponding positioning hole and the end of the mesh belt installation positioning plate 2 and the mesh belt member 4 are fixed by magnetic adsorption; then the belt conveyor structure rotates, and the mesh belt member 4 is gradually wound around the belt conveyor structure. In this process, the mesh belt reel device 5 and the belt conveyor structure tighten the mesh belt member 4 to ensure that the mesh belt member 4 is well attached to the belt conveyor structure; when the belt conveyor structure rotates one circle, the positioning hole at the other end of the mesh belt member 4 is sleeved on the locating pin 206 and also fixed by magnetic adsorption, so that the mesh belt member 4 can be quickly installed and replaced.

[0041] It should be noted that, see Figure 8 The left end of the dryer body 1 has a loading mechanism 101 and a discharging mechanism 102 (existing design), and the right end has a window 103.

[0042] like Figure 3 As shown, the belt conveyor structure is a metal mesh belt device 3 (which is prior art and can be purchased from, for example, Anping County Junqi Wire Mesh Products Co., Ltd.). Specifically, the metal mesh belt device 3 includes a metal mesh belt 303 and a rotating shaft. Fixed baffles 302 are passed through both sides of the metal mesh belt 303. A transmission chain 301 is provided on the outer side of the baffle 302. The rotating shaft drives the entire metal mesh belt 303.

[0043] The setting of the metal mesh belt device 3 can provide sufficient support for the mesh belt member 4 and facilitate the fixation of the mesh belt mounting positioning plate 2; and the sufficiently large pores will not adversely affect the drying of the material on the mesh belt member 4.

[0044] like Figure 3 As shown, the mesh belt mounting positioning plate 2 is designed; specifically, it includes a positioning plate 202 and a positioning pressure plate 203. The positioning plate 202 has a positioning pin 206 and is fixed with a high-temperature resistant samarium cobalt magnet 201. The positioning plate 202 and the positioning pressure plate 203 are clamped and fixed to the belt conveyor structure from the top and bottom and are fixed by two screws 205 and two washers 204. The mesh belt mounting positioning plate 2 can be quickly fixed.

[0045] like Figure 4As shown, the mesh belt member 4 is designed. Specifically, in the mesh belt member 4, the metal positioning plates arranged at both ends of the mesh belt 403 are respectively metal positioning plate 1 404 and metal positioning plate 2 401; positioning holes are opened on the metal positioning plate 1 404 and metal positioning plate 2 401, and a high-temperature resistant samarium cobalt magnet 2 402 is fixed on the metal positioning plate 2 401.

[0046] like Figure 5 As shown, the mesh belt reel device 5 is designed, which includes a reel 503 and a reel mounting shaft 506; one end of the reel mounting shaft 506 is mounted on the dryer body 1 and the other end is free; the reel 503 is sleeved on the reel mounting shaft 506, and the mesh belt member 4 is wound on the reel 503, and the reel 503 is also provided with a hand crank handle 502;

[0047] This structural design is conducive to gradually releasing the mesh belt 4 through the hand crank handle 502, and the mesh belt 4 can be tightened by controlling the rotation of the hand crank handle 502, that is, the mesh belt reel device 5 rolls up the mesh belt 4, and according to the rotation speed of the belt conveyor structure, the mesh belt 4 is adaptively released through the hand crank handle 502, so that the mesh belt 4 fits well on the belt conveyor structure.

[0048] Furthermore, a plurality of mounting shaft positioning plates 505 are provided at different heights from top to bottom on the dryer body 1; Figure 5 As shown, the dryer body 1 is provided with a mounting shaft positioning plate 507 and a mounting shaft positioning plate 508. The mounting shaft positioning plate 505 has a plurality of slots. The reel mounting shaft 506 is inserted into the corresponding slots and is locked and fixed by a locking pin 504 (locked by threads).

[0049] Based on the above-mentioned quick mesh belt replacement device of the mesh belt dryer, the present invention also discloses a method for quickly replacing the mesh belt of the mesh belt dryer, comprising the following steps:

[0050] S1. Rotate the belt conveyor structure and stop when the mesh belt mounting plate 2 on it approaches the window 3; if there is a mesh belt member 4 on the rotating belt conveyor structure, remove it;

[0051] S2. Insert one end of the high-temperature resistant polyester mesh belt 4 mounted on the reel 503 into the dryer body 1 through the window 3. Fit the positioning hole of the metal positioning plate 404 on this end over the positioning pin 206 on the mesh belt mounting positioning plate 2. Also, allow the high-temperature resistant samarium-cobalt magnet 201 to attract the metal positioning plate 404.

[0052] S3. Rotate the belt conveyor structure one circle, and tighten the high-temperature resistant polyester mesh belt 4 through the mesh belt reel device 5, and attach the high-temperature resistant polyester mesh belt 4 to the belt conveyor structure; then buckle the metal positioning plate 2 401 at the end of the mesh belt 4 into the positioning pin 206 of the positioning plate 202 of the mesh belt installation positioning plate 2, and adsorb the metal positioning plate 2 401 onto the metal positioning plate 1 404 through the high-temperature resistant samarium cobalt magnet 2 402 bonded to the metal positioning plate 2 401.

[0053] It should be noted that there is also another removal positioning pin 206 on the reel 503. In step S1, when a smaller-aperture mesh belt is needed or a large-aperture metal mesh belt needs to be restored, when the mesh belt part 4 needs to be removed: the dryer is controlled to rotate the metal mesh belt device 3 so that the mesh belt installation positioning plate 2 installed on the metal mesh belt device 3 rotates to a position close to the window 103 and then stops, the metal positioning plate 2 401 at the end of the high-temperature resistant polyester mesh belt part 4 is taken out and buckled into the corresponding removal positioning pin 206 on the reel 503 of the mesh belt reel device 5, the operator controls the metal mesh belt device 3 to rotate one circle, and rotates the hand crank 502 on the mesh belt reel device 5 to complete the recovery of the mesh belt part 4;

[0054] It should also be noted that multiple mesh belt reels 5 can be set at the window 103 of the dryer, one for retrieving the mesh belt 4 and the other for reeling in mesh belts of different mesh sizes 4. The mesh belt 4 of the corresponding mesh size can be selected as needed.

[0055] The above embodiments merely represent preferred implementations, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art will be able to make various modifications and improvements without departing from the scope of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
