Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to an impact crusher dust collector with low dust overflow. Background Art

[0002] The impact crusher dust collector is a highly efficient dust removal device designed to address the dust problem generated during the operation of impact crushers. Its primary function is to capture dust generated during the crushing process, reducing environmental pollution and protecting the health of operators. Compared to other types of crushing equipment dust collectors, the impact crusher dust collector offers advantages such as simple structure, easy operation, and high dust removal efficiency.

[0003] The dust removal device in an impact crusher dust collector typically utilizes a flip valve. Its operating principle is based on its internal flap structure. Specifically, the flap valve can be controlled to open and close by rotating a shaft. When opened, fluid flows through the valve's inlet channel. Simultaneously, pressure acts on the valve flap, which rotates the shaft on the flap, aligning it with the inlet channel, allowing fluid to flow. When closed, the shaft rotates, positioning the flap perpendicular to the inlet channel, preventing fluid from passing.

[0004] In the prior art, when a flip valve is used for dust discharge, long-term use of the flip valve will cause gaps in the flip valve connection, and the pipeline will be unable to lock the air, resulting in dust overflow in the pipeline during the back-blowing cleaning process of the dust collector, and causing dust leakage, affecting the dust removal effect. Therefore, the present application provides a low-dust overflow back-blowing dust collector to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a low dust overflow back-blowing dust collector to solve the problem that when the existing flip valve is used for dust discharge for a long time, gaps will appear in the flip valve connection, and the pipeline cannot lock the air, which will lead to dust overflow in the pipeline during the back-blowing cleaning process of the dust collector, causing dust leakage and affecting the dust removal effect.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a low-dust overflow impact crusher dust collector, comprising: a dust collector dust hopper; a discharge box, installed at the bottom of the dust collector dust hopper, for receiving dust discharged from the dust collector dust hopper; a rotating part, located in the discharge box, for receiving the dust discharged from the dust collector dust hopper and transferring the dust to the outside of the discharge box; a shielding part, located on the rotating part, for increasing the length of the rotating part so that there is no gap between the rotating part and the side wall of the discharge box during rotation; an elastic part, located on the rotating part, and is configured to change the length of the rotating part increased by the shielding part; a driving part, located on the discharge box, for driving the rotating part to rotate.

[0007] Preferably, the rotating part includes: a rotating shaft, which is installed in the discharge box and is rotatably connected to the inner wall of the discharge box on opposite sides, and one end is connected to the output end of the driving part so that the rotating shaft rotates under the drive of the driving part; a rotating frame, which is installed on the rotating shaft and is configured to rotate with the rotating shaft.

[0008] Preferably, the rotating frame includes: multiple groups of receiving plates, evenly installed on the outer wall of the rotating shaft, and the number of receiving plates is an even number, and is arranged so that during the rotation of the two groups of receiving plates symmetrical about the central axis of the rotating shaft, there is no gap between the two groups of receiving plates and the side wall of the discharge box.

[0009] Preferably, the shielding part includes: a shielding plate, which is installed on the side of the receiving plate that rotates first and is slidably connected to the receiving plate, and is used to increase the length of the receiving plate so that the receiving plate is in contact with the side wall of the discharge plate during the entire process of rotation in the discharge box.

[0010] Preferably, it also includes: a slide groove, which is opened on the receiving plate; a sliding block, which is installed in the slide groove and connected to the baffle plate, and is configured so that when the side wall of the discharge box pushes the baffle part, the sliding block slides in the slide groove so that the baffle plate slides following the sliding block.

[0011] Preferably, the elastic part includes: a fixed plate, which is installed on the supporting plate and is on the same side as the shielding plate, and the distance between it and the rotating axis is smaller than the distance between the shielding plate and the rotating axis; multiple groups of springs, all installed between the fixed plate and the shielding plate, and are arranged so that when the side wall of the discharge box does not push the shielding plate, the springs push the shielding plate close to the side wall of the discharge box; multiple groups of telescopic rods, which are installed between the fixed plate and the shielding plate, and each group of springs is equipped with a group of telescopic rods so that the springs push the shielding plate in a straight line.

[0012] Preferably, the shielding plate is tilted close to the side wall of the discharge box, and the tilting direction is from the side close to the shielding plate to the side away from the shielding plate.

[0013] Preferably, the rotating shaft rotates counterclockwise when viewed from the driving portion, so that the side wall of the discharge box pushes the shielding portion.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: 1. In the above scheme, by setting a rotating part, the way of discharging dust by the flip valve is changed, so that the dust enters between the two groups of receiving plates of the rotating part. Under the push of the receiving plates, the dust is driven to rotate and discharged from the bottom of the discharge box, avoiding the dust accumulated at the bottom of the discharge box from re-entering the discharge box in the case of reflux.

[0015] 2. By setting the shielding part and the elastic part, during the rotation of the rotating part, the shielding plate slides in the slide groove and is pushed elastically by the spring during the rotation of the receiving plate, thereby changing the extension length of the receiving plate, so that the receiving plate and the shielding plate are always in contact with the side wall of the discharge box.

It is also noted that, to provide a more detailed description, the following embodiments are best and preferred embodiments, and those skilled in the art may employ alternative implementations for some known technologies. Furthermore, the accompanying drawings are intended only to provide a more detailed description of the embodiments and are not intended to limit the present invention.

[0025] Example 1: Figures 1 to 4As shown, an embodiment of the present invention provides a low-dust overflow impact crusher dust collector, comprising: a dust collector dust hopper 1; a discharge box 2, installed at the bottom end of the dust collector dust hopper 1, for receiving dust discharged from the dust collector dust hopper 1; a rotating part, located in the discharge box 2, for receiving the dust discharged from the dust collector dust hopper 1 and transferring the dust to the outside of the discharge box 2; a shielding part, located on the rotating part, for increasing the length of the rotating part so that there is no gap between the rotating part and the side wall of the discharge box 2 during the rotation process; an elastic part, located on the rotating part, and is configured to change the length of the rotating part increased by the shielding part; a driving part 3, located on the discharge box 2, for driving the rotating part to rotate; the driving part 3 adopts a driving motor to provide rotational force for the rotating shaft 4.

[0026] like Figures 1 to 4 As shown, the rotating part includes: a rotating shaft 4, which is installed in the discharge box 2 and is rotatably connected to the opposite sides of the inner wall of the discharge box 2, and one end is connected to the output end of the driving part 3, so that the rotating shaft 4 rotates under the drive of the driving part 3; a rotating frame 5, which is installed on the rotating shaft 4 and is configured to rotate with the rotating shaft 4.

[0027] like Figures 1 to 4 As shown, the rotating frame 5 includes: multiple groups of receiving plates 6, which are evenly installed on the outer wall of the rotating shaft 4, and the number of receiving plates 6 is an even number. It is arranged that during the rotation of the two groups of receiving plates 6 symmetrical about the central axis of the rotating shaft 4, there is no gap between the two groups of receiving plates 6 and the side wall of the discharge box 2.

[0028] Example 2: Figures 1 to 4 As shown, the shielding part includes: a shielding plate 7, which is installed on the side of the receiving plate 6 that rotates first and is slidably connected to the receiving plate 6, and is used to increase the length of the receiving plate 6 so that the receiving plate 6 is in contact with the side wall of the discharge plate during the entire process of rotation in the discharge box 2.

[0029] like Figures 1 to 4 As shown, it also includes: a slide groove 8, which is opened on the receiving plate 6; a sliding block 9, which is installed in the slide groove 8 and connected to the baffle plate 7, and is configured so that when the side wall of the discharge box 2 pushes the baffle part, the sliding block 9 slides in the slide groove 8, so that the baffle plate 7 slides following the sliding block 9.

[0030] like Figures 1 to 4As shown, the elastic part includes: a fixed plate 10, which is installed on the receiving plate 6 and is on the same side as the baffle plate 7, and the distance between it and the rotating shaft 4 is smaller than the distance between the baffle plate 7 and the rotating shaft 4; multiple groups of springs 11, all installed between the fixed plate 10 and the baffle plate 7, and are arranged to push the baffle plate 7 close to the side wall of the unloading box 2 when the side wall of the unloading box 2 does not push the baffle plate 7; multiple groups of telescopic rods 12, which are installed between the fixed plate 10 and the baffle plate 7, and each group of springs 11 is equipped with a group of telescopic rods 12, so that the springs 11 push the baffle plate 7 in a straight line.

[0031] like Figure 4 As shown, the shielding plate 7 is tilted near the side wall of the discharge box 2, and the tilting direction is from the side close to the shielding plate 7 to the side away from the shielding plate 7; the shielding plate 7 is tilted near the side wall of the discharge box 2 so that when the shielding plate 7 contacts the side wall of the discharge box 2 during rotation, the inclined surface contacts the side wall first to prevent the side wall from being unable to push the shielding plate 7, thereby causing the rotating shaft 4 to stop rotating.

[0032] The rotating shaft 4 rotates counterclockwise when viewed from the driving portion 3 so that the side wall of the discharge box 2 pushes the shielding portion; when the user stands on the side of the discharge box 2 close to the driving portion 3, the rotating frame 5 rotates counterclockwise.

[0033] The technical solution provided by the present invention is that after the dust is discharged from the bottom end of the dust collecting hopper 1 of the dust collector, it enters the discharge box 2. After entering the discharge box 2, the dust falls on the rotating frame 5 and is located between the two sets of receiving plates 6. The driving part 3 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the rotating frame 5 to rotate, thereby driving the receiving plate 6 to rotate. During the rotation process, when the receiving plate 6 rotates to the horizontal plane, except for one side contacting the rotating shaft 4, the other three sides of the receiving plate 6 are in contact with the side wall of the discharge box 2. After the receiving plate 6 continues to rotate, the side away from the rotating shaft 4 stops contacting the side plate, and the shielding plate 7 is under the action of the spring 11. When the support plate 6 is in contact with the rotating shaft 4, the other three sides of the support plate 6 are in contact with the side wall of the discharge box 2.

[0034] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
