[0026] In order to make those skilled in the art better understand the technical scheme of the present application, the present application will be further described in detail with reference to the accompanying drawings.

[0027] As Figures 1-5 shown, the dust removal and recycling device of the closed dry acetylene feeding system provided by the embodiments of the present application includes a raw material bin 1, a feeding opening 2 is communicated on the raw material bin 1, a filter plate 3 is arranged on the feeding opening 2, the filter plate 3 is used for filtering raw materials, a scraper 4 is arranged on the filter plate 3, and the scraper 4 is driven to rotate on the filter plate 3.

[0028] Specific, the raw material bin 1 is arranged vertically, and the number of raw material bins 1 is preferably three, and the top of the raw material bin 1 is communicated with a feeding port 2, which is used to put the external raw material into the raw material bin 1, and the upper side of the feeding port 2 is provided with a feeding mechanism such as a feeding belt, which is used to convey a certain amount of raw material into the feeding port 2 for feeding operation, and in the feeding process, in order to avoid the generation of calcium carbide dust, a plurality of bag dust collectors are arranged on the feeding mechanism, and the dust collecting port communicated with the bag dust collector is used to suck the calcium carbide powder generated, and then the ash discharge pipe communicated with the bag dust collector is used to convey the sucked calcium carbide powder back to the inside of the raw material bin 1 for recycling. The filter plate 3 is horizontally arranged in the feeding port 2 to filter the raw material put into the feeding port 2, and the above is prior art and will not be described in detail.

[0029] The innovation of the embodiment is that the filter plate 3 is provided with a scraper 4, which is driven to rotate on the filter plate 3.

[0030] Specifically, the bottom of the filter plate 3 is provided with a motor 5, the output shaft of the motor 5 penetrates the filter plate 3 and extends to the top of the filter plate 3, one end of the output shaft of the motor 5 extending to the top of the filter plate 3 is connected with the scraper 4; two baffles 6 are rotatably connected on both sides of the opening of the feeding port 2, the bottom of each baffle 6 is provided with a reset spring 7, the bottom end of the reset spring 7 is connected with the inner wall of the feeding port 2; two connecting blocks 8 are fixedly connected on both sides of the inner wall of the feeding port 2 and below the filter plate 3, a connecting rod 9 is slidably connected on each connecting block 8, the top end of the connecting rod 9 is connected with the bottom of the filter plate 3, an extrusion spring 10 is sleeved on the outer surface of the connecting rod 9, the top end of the extrusion spring 10 is connected with the filter plate 3, and the bottom end of the extrusion spring 10 is connected with the connecting block 8; and the filter plate 3 is slidably connected on both sides in the feeding port 2.

[0031] In the embodiment, the scraper 4 is slidably connected with the filter plate 3, and the motor 5 is started to drive the output shaft of the motor 5 to slide and rotate the scraper 4 on the filter plate 3, so as to push and disperse the raw material accumulated on the filter plate 3 for re-filtering, avoiding the accumulation on the filter plate 3, thereby affecting the filtering effect;

[0032] Please refer to Figure 2As shown, two said baffles 6 are in horizontal abutting state in initial state, when raw materials are put into the charging port 2, under the action of gravity, the baffle 6 appears inclined swing, that is, the opening of the charging port 2 is opened, so that the raw materials enter the inside of the charging port 2, after entering, stop feeding, and the rebound of the reset spring 7 pushes the baffle 6 to reverse inclined swing, so as to restore to the horizontal state, so as to shield the opening of the charging port 2, avoid the raw materials after feeding from the raw material bin 1;

[0033] When the raw materials enter the inside of the charging port 2, if there are more blocky raw materials in the raw materials, a certain impact force will be generated in the falling process, and the filter plate 3 is passively downwardly slid on the inner wall of the charging port 2, so as to compress the compression spring 10 to deform, thereby buffering the impact force generated in the falling process of the raw materials, avoiding direct action on the filter plate 3, thereby causing deformation of the filter plate 3.

[0034] In the above description, the baffle 6 has two working states:

[0035] When the baffle 6 is in the first working state, that is, the baffle 6 is arranged in the horizontal state, thereby shielding the opening of the charging port 2;

[0036] When the baffle 6 is in the second working state, that is, the baffle 6 is arranged in the inclined state, thereby putting the external raw materials into the inside of the charging port 2;

[0037] Specifically, when switching from the first state to the second state, when the raw materials fall and contact the baffle 6, the baffle 6 is passively swung under the action of gravity, so that the raw materials on the baffle 6 enter the inside of the charging port 2.

[0038] In the above description, the switching action from the first state to the second state is switched by the weight of the raw materials, specifically, when filtering the raw materials (first step), the raw materials are fed into the inside of the charging port 2 by the feeding mechanism, before entering the charging port 2, the weight of the raw materials presses the baffle 6, drives the baffle 6 to passively swing, so that the raw materials enter the inside of the charging port 2, then fall on the filter plate 3 for filtering, after the feeding is completed, the rebound of the reset spring 7 pushes the baffle 6 to reverse swing to restore to the initial state, that is, the horizontal state, thereby shielding the opening of the charging port 2, avoiding the raw materials from floating out;

[0039] When the raw materials fall onto the filter plate 3 inside the feeding port 2 (second step), if the raw materials contain a large amount of blocky raw materials, the falling process will generate a certain impact force on the filter plate 3, so that the filter plate 3 performs filtering and downward sliding on the inner wall of the feeding port 2 at the same time, so as to compress the compression spring 10 to deform, thereby buffering the impact force generated in the falling process of the raw materials, avoiding direct action on the filter plate 3, thereby causing deformation of the filter plate 3;

[0040] When the amount of raw materials is too large (third step), and the raw materials accumulated on the filter plate 3 cannot be filtered, the motor 5 is started to drive the scraper 4 to rotate and slide on the filter plate 3, thereby pushing the raw materials accumulated on the filter plate 3, so that the accumulated raw materials can be dispersed and filtered, thereby improving the filtering effect.

[0041] The beneficial effect of the embodiment is that the scraper 4 can push and disperse the raw materials accumulated on the filter plate 3, so that the accumulated raw materials can increase the contact area with the filter plate 3, thereby being filtered by the filter plate 3, so as to avoid accumulation on the filter plate 3, thereby affecting the normal filtering effect.

[0042] The above only describes some exemplary embodiments of the present application by way of illustration, without doubt, for ordinary skilled in the art, without departing from the spirit and scope of the present application, the described embodiments can be modified in various ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the present application.
