Description

Technical Field

[0001] This utility model relates to the field of vibrating screening technology, specifically a double-layer vibrating screen for carbonizing walnut shells. Background Technology

[0002] Walnut shell carbonization refers to the process of treating walnut shells at high temperatures in an oxygen-deficient or low-oxygen environment, causing them to undergo a pyrolysis reaction and transform into charcoal. Because the particle size of carbonized walnut shells may vary, a sieving device is needed to separate particles of different sizes, ensuring a more consistent particle size distribution within the same batch of products.

[0003] Traditional vibrating screens lack effective structures to prevent material accumulation. Material accumulation can affect screening efficiency, leading to insufficient screening and reduced equipment efficiency. Therefore, it is necessary to develop a double-layer vibrating screen for carbonized walnut shells. Utility Model Content

[0006] A double-layer vibrating screen for carbonizing walnut shells, comprising a screening drum and a rotating rod:

[0007] The screening barrel is a hollow cylindrical shape with an open top wall. Two screening screens are fixedly installed in the inner cavity of the screening barrel from top to bottom. The two screening screens divide the inner cavity of the screening barrel into three chambers. A vertical double-headed motor is fixedly installed at the bottom center of the screening barrel. An eccentric block is fixedly installed on the output shaft at the lower end of the double-headed motor.

[0008] The lower end of the rotating rod is fixedly connected to the output shaft of the double-headed motor via a reducer and a coupling. The rotating rod rotates through the bottom wall of the screening barrel and the center of the two screening screens. A horizontal mounting rod is fixedly installed at the position of the rotating rod in each chamber. A row of first springs is arranged along the length of the mounting rod at its bottom. A lever is fixedly installed at the bottom of the row of first springs.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figures 1-6 The diagram shown is a structural schematic of an embodiment of the carbonized walnut shell double-layer vibrating screen of this utility model. Please refer to [link / reference]. Figures 1-6 This paper provides a detailed introduction to a double-layer vibrating screen for carbonizing walnut shells.

[0028] Example 1: A double-layer vibrating screen for carbonizing walnut shells, comprising a screening drum 100 and a rotating rod 200:

[0029] The screening barrel 100 is a hollow cylindrical shape with an open top wall. Two screening screen plates 101 are fixedly arranged at intervals from top to bottom in the inner cavity of the screening barrel 100. The two screening screen plates 101 divide the inner cavity of the screening barrel 100 into three chambers. A vertical double-head motor 102 is fixedly arranged at the bottom center of the screening barrel 100. An eccentric block 103 is fixedly arranged on the output shaft at the lower end of the double-head motor 102. The double-head motor 102 drives the eccentric block 103 to rotate, causing the entire screening barrel 100 to vibrate.

[0030] The lower end of the rotating rod 200 is fixedly connected to the output shaft of the double-headed motor 102 via a reducer and a coupling. The reducer prevents the double-headed motor 102 from driving the rotating rod 200 to rotate too quickly. The rotating rod 200 rotates through the bottom wall of the screening barrel 100 and the center of the two screening screen plates 101. A transverse mounting rod 201 is fixedly installed on the rotating rod 200 at the position of each chamber. A row of first springs 202 is arranged along the length of the bottom of the mounting rod 201. A lever 203 is fixedly installed at the bottom of the row of first springs 202. The bottoms of the three levers 203 are respectively... The screen plate 101 and the bottom of the inner cavity of the screening barrel 100 are in intermittent contact. Since the screening barrel 100 is in a state of vibration, a first spring 202 is provided between the lever 203 and the mounting rod 201. This ensures that when the device is in use, the surface of the screen plate 101 in a state of vibration will not directly and rigidly contact the lower part of the lever 203. Instead, the first spring 202 assists in the contact between the two, so that the lever 203 can intermittently contact the surface of the screen plate 101 and move the material on the screen plate 101, avoiding material accumulation and preventing collision damage to the surface of the screen plate 101.

[0031] Furthermore, the mesh size of the upper screening screen 101 is larger than that of the lower screening screen 101, thus achieving multi-layer screening.

[0032] Furthermore, the bottom of the screening barrel 100 is fixedly equipped with support springs 104 at equal intervals around its central axis. Multiple support springs 104 are vertically arranged and their bottom ends are all provided with an annular support base 105. The eccentric block 103 is located inside the support base 105 and the outer side of the eccentric block 103 always maintains a distance from the inner side of the dual-head motor 102. The support base 105 can be fixed in the required installation position. The support springs 104 are made of high-strength material and are used to support the vibration of this device.

[0033] Furthermore, the bottom of the side walls of the three chambers are provided with discharge ports 106 for discharging materials. The side wall of the screening barrel 100 is provided with discharge pipes 107 that connect the three discharge ports 106. The three discharge pipes 107 are arranged in an alternating manner, which makes it convenient to place collection frames and the like below the discharge pipes 107 to receive the screened materials.

[0034] In Example 2, based on Example 1, circular through holes 204 are opened at the center of the two screening screen plates 101 and the center of the bottom wall of the inner cavity of the screening barrel 100. The shaft of the rotating rod 200 passes through the center of the three through holes 204, and the rotating rod 200 is spaced apart from the through holes 204. Bearings 205 are rotatably mounted on the shaft of the rotating rod 200 at the positions of the three through holes 204. A first bearing 205 is fixedly installed around the outer side of each bearing 205 at equal intervals with the vertical axis of the rotating rod 200 as the center. The second spring 206 has its other end fixed to the inner wall of the through hole 204. Since the screening screen plate 101 is in a vibrating state when the device is in use, and the rotating rod 200 needs to rotate continuously, the connection between the rotating rod 200 and the vibrating screening screen plate 101 is prone to wear. Therefore, the bearing 205 and the through hole 204 are connected by the second spring 206. When the rotating rod 200 rotates, even if the screening screen plate 101 vibrates, the impact on the rotating rod 200 is relatively small.

[0035] Furthermore, a baffle 207 is fixedly installed above each through hole 204 on the rod body of the rotating rod 200. The outer diameter of the baffle 207 is larger than the inner diameter of the through hole 204. Since the inner side of the through hole 204 and the outer side of the rotating rod 200 are spaced apart, the baffle 207 is added to reduce the material from slipping through the gap between them.

[0036] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
