Utility Model Content

[0005] In order to reduce dust pollution caused by the operation of a single-cone dryer, the present application provides a clean single-cone dryer for chemical powders.

[0006] The present application provides a clean chemical powder single cone dryer, which adopts the following technical solution:

[0007] A clean chemical powder single cone dryer comprises a frame and a dryer body arranged on the frame, wherein the frame is provided with a dust removal device for cleaning dust generated by the dryer body, and the dust removal device comprises:

[0008] A dust removal cover, wherein the dust removal cover is vertically slidably arranged on the frame;

[0009] A limiting mechanism, which is arranged on the frame and is used to limit the vertical position of the dust cover, and the dust cover covers the dryer body under the action of the limiting mechanism;

[0011] The dust collecting mechanism is arranged on the frame and is used for collecting the dust blown out from the dust collecting cover by the dust removing fan.

[0012] By adopting the above technical solution, the dust removal hood is moved to cover the dryer body and the limit mechanism is locked, and then the dust removal fan is started. The dust removal fan starts to blow air to the dust removal hood, and the dust in the dust removal hood is blown into the dust collecting mechanism for unified collection and treatment, thereby reducing the probability of dust generated by the dryer body during operation spreading in the working environment and causing pollution to the working environment.

[0013] Optionally, the dust hood has a cover body made of a bellows, one end of the dust hood is connected to a dust removal fan, and the other end of the dust hood can be freely telescopically moved.

[0014] By adopting the above technical solution, the cover body of the dust hood is set to be a cover body made of a bellows, so that when the dryer body is feeding or other operations requiring manual operation, the dust hood can be opened to operate the dryer body, and when the dryer body is working, the dust hood can be moved to cover the dryer body. The structure is simple, convenient and fast, and the working efficiency is high.

[0015] Optionally, the limiting mechanism includes:

[0016] A first limiting ring, wherein the first limiting ring is arranged on the frame;

[0017] A second limiting ring, wherein the second limiting ring is arranged on the dust cover, and the diameter of the first limiting ring is greater than the diameter of the second limiting ring;

[0018] A limit block, wherein a horizontal sliding groove is provided on the inner side wall of the first limit ring, and the limit block is slidably arranged on the sliding groove;

[0019] A limit spring, a horizontal limit groove is opened on the outer side wall of the second limit ring, the limit spring is arranged on the sliding groove and connected with the limit block, and the limit block, under the action of the limit spring, has its head passing out of the sliding groove and plugged into the limit groove;

[0020] A pull rod is horizontally slidably arranged on the first limiting ring, one end of the pull rod is located outside the first limiting ring, and the other end of the pull rod extends into the sliding groove and is connected to the limiting block.

[0021] By adopting the above technical solution, a first limit ring is installed on the frame. When the dust hood is moved to cover the dryer body, the pull rod is pulled to drive the limit block to move into the sliding groove as a whole. Then the second limit ring installed on the dust hood is inserted into the first limit ring. The pull rod is released, and the limit block, under the action of the limit spring, the head of the limit block passes through the sliding groove and engages with the limit groove, thereby completing the position limitation of the dust hood and reducing the probability of the dust hood being blown open when the dust removal fan blows air into the dust hood.

[0023] By adopting the above technical solution, an arc-shaped guide surface is provided on the side wall of one end of the limit block extending out of the sliding groove, so that when the second limit ring is inserted into the first limit ring, the second limit ring will first contact the guide surface of the limit block, and the guide surface will generate a component force to drive the limit block to move into the sliding groove, thereby eliminating the need to manually pull the pull rod to move the limit block into the sliding groove, thereby simplifying the working steps, reducing the work intensity, and improving the work efficiency.

[0024] Optionally, a hook is rotatably provided on the dust removal fan, and when the dust removal cover is retracted to its minimum length, the second limiting ring is hung on the hook.

[0025] By adopting the above technical solution, a hook is installed on the dust removal fan. When the dust hood is retracted to the minimum length, the second limiting ring is hung on the hook, thereby completing the limiting work of the dust hood in the retracted state. When the dust hood needs to be used, it is only necessary to remove the second limiting ring from the hook. It is convenient and quick with high work efficiency.

[0030] By adopting the above technical solution, the dust removal fan is started to blow the dust in the dust hood into the dust collecting pipe, and the high-voltage electrostatic plate is energized to electrostatically adsorb the dust entering the dust collecting pipe. The adsorbed dust is collected uniformly and centrally through the dust collecting box, thereby completing the collection and treatment of the dust discharged from the dust hood.

[0031] Optionally, a vibration component is provided on the dust collecting pipe, and the vibration component is used to vibrate the high-voltage electrostatic plate to make the dust adsorbed on the high-voltage electrostatic plate fall into the dust collecting box, and the vibration component includes:

[0032] A vibration block, the vibration block is rotatably arranged on the dust collecting pipe;

[0033] A vibration motor is arranged on the dust collecting pipe and an output shaft is connected with a vibration block. The vibration block rotates under the action of the vibration motor and continuously collides with the high-voltage electrostatic plate.

The rotation of the vibration block continuously collides with the high-voltage electrostatic plate, thereby vibrating the dust adsorbed on the high-voltage electrostatic plate into the dust collecting box, reducing the probability that the dust is still adsorbed on the high-voltage electrostatic plate and does not fall into the dust collecting box when the high-voltage electrostatic plate is powered off.

[0035] Optionally, a movable hole is provided on the side wall of the dust box, and a movable frame is horizontally slidably provided on the dust box, the movable frame is located in the movable hole, and the movable frame receives the dust that falls into the dust box.

[0036] By adopting the above technical solution, a movable frame is slidably installed on the dust box, and the movable frame receives the dust entering the dust box. When the movable frame is full of dust, the movable frame is removed from the dust box to dump the dust, thereby completing the processing of the dust collected in the dust box.
