Description

Technical Field

[0001] This utility model relates to the field of rotary drum technology, and in particular to an automatic feeding and discharging device for controlling a rotary drum. Background Technology

[0002] A rotary drum is a common industrial equipment component used for mixing various materials or drying materials to remove surface moisture. The drum achieves specific process operations through rotation around its axis. The drum body may have various structures, such as screens, blades, heating or cooling jackets, to meet different process requirements.

[0003] Since the drum achieves the mixing effect by rotating, each feeding and discharging operation requires manual operation, which is cumbersome and slow, resulting in a decrease in overall production efficiency. Therefore, an automatic feeding and discharging device for controlling the drum is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic feeding and discharging device for controlling a rotating drum.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting up multiple valves and valve pipe structures, proximity switches are used to detect the position of the round pipe. When the round pipe is facing upward, it can connect with the raw material silo to realize material replenishment. When the round pipe is facing downward, it can connect with the finished product silo to realize material discharge. This process is repeated to achieve automatic material replenishment and discharge, thereby improving production efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1 to 3 An automatic feeding and discharging device for controlling a rotating drum includes a support base 1. A rotating drum body 2 is movably mounted in the middle of the support base 1. A circular tube 3 is fixedly connected to the outer surface of the rotating drum body 2. An electric butterfly valve 61 is installed at the end of the circular tube 3. A short section B62 is installed above the electric butterfly valve 61. A proximity switch 63 is installed on the outer surface of the short section B62. A raw material hopper 4 is fixedly mounted on the upper part of the support base 1. A pneumatic slide gate valve A71 is installed at the bottom of the raw material hopper 4. A telescopic valve A72 is installed at the bottom of the pneumatic slide gate valve A71. A short section A73 is installed at the bottom of the telescopic valve A72. A bracket A74 is sleeved on the outer surface of the short section A73. A cover valve A75 is installed in the middle of section 4. When the proximity switch 63 detects that the drum body 2 has entered the designated position, the cover valve A75 opens, the telescopic valve A72 moves from the retracted state to the extended state, the short section A73 and the short section B62 are connected, the electric butterfly valve 61A opens, and then the pneumatic slide gate valve A71 opens. The material enters the drum body 2 from the material raw material hopper. When a certain amount of material is discharged from the material raw material hopper, the pneumatic slide gate valve A71 closes, the electric butterfly valve 61A closes, the telescopic valve A72 moves from the extended state to the retracted state, the short section A73 and the short section B62 separate, the cover valve A75 closes, and the drum body 2 is replenished.

[0022] Reference Figure 1 , Figure 3 and Figure 4 A vertical rod 81 is fixedly connected to the lower surface of the raw material silo 4. A shaft 82 is rotatably connected to the bottom end of the vertical rod 81. A gear 83 is fixedly sleeved on the outer surface of the shaft 82. A rack 84 is embedded in the upper part of the valve stem of the pneumatic slide valve A71. Elliptical plates 85 are fixedly connected to both ends of the shaft 82. A slide rod 86 is movably engaged with the inner wall of the elliptical plate 85. A top rod 87 is sleeved on the outer surface of the slide rod 86. A limit rod 88 is movably inserted through the middle of the top rod 87. During the operation of the device, the rack 84 is pulled to drive the gear 83 to rotate, which in turn drives the elliptical plates 85 at both ends of the shaft 82 to rotate. The slide rod 86 will make linear reciprocating motion as the elliptical plate 85 rotates, which will drive the top rod 87 to move. Since the top rod 87 is limited by the limit rod 88, it can only make linear motion. Therefore, the top rod 87 will collide with the device to generate vibration, promote the discharge of materials, and avoid blockage due to friction.

[0023] Reference Figure 1 , Figure 2 and Figure 5The lower part of the drum body 2 is provided with a finished product compartment 5. The top of the finished product compartment 5 is provided with a pneumatic slide gate valve B91. The bottom of the pneumatic slide gate valve B91 is provided with a telescopic valve B92. The bottom of the telescopic valve B92 is provided with a short section C93. The outer surface of the short section C93 is fitted with a bracket B94. The middle of the bracket B94 is provided with a cover valve B95. When the proximity switch 63 detects that the drum body 2 has entered the designated position, the cover valve B95 opens, and the telescopic valve B92 retracts. When the drum body 2 reaches the extended state, short sections C93 and B62 are connected, the pneumatic slide gate valve B91 opens, and then the electric butterfly valve 61A opens. The material enters the finished product hopper from the drum body 2. When the material in the finished product hopper reaches a certain position, the electric butterfly valve 61A closes, the pneumatic slide gate valve B91 closes, the telescopic valve B92 moves from the extended state to the retracted state, short sections C93 and B62 separate, the cover valve B95 closes, and the discharge from the drum body 2 is completed.

[0024] The specific working principle of this utility model is as follows: When the drum body 2 needs to be replenished, the operator clicks the replenishment button on the host computer interface. Then the drum body 2 slowly rotates to the position where the round tube 3 is facing upward. When the proximity switch 63 detects that the drum body 2 has entered the designated position, the cover valve A75 opens, the telescopic valve A72 moves from the contracted state to the extended state, the short section A73 and the short section B62 are connected, the electric butterfly valve 61A is opened, and then the pneumatic slide valve A71 is opened. The material enters the drum body 2 from the material raw material hopper. When a certain amount of raw material is discharged from the material raw material hopper, the pneumatic slide valve A71 closes, the electric butterfly valve 61A closes, the telescopic valve A72 moves from the extended state to the contracted state, the short section A73 and the short section B62 separate, and the cover valve A75 closes. At this time, the drum body 2 is replenished and enters the mixing or drying state.

[0025] When the drum body 2 needs to discharge material, the operator clicks the discharge button on the host computer interface. Then, the drum body 2 slowly rotates to the position where the round tube 3 is facing down. When the proximity switch 63 detects that the drum body 2 has entered the designated position, the cover valve B95 opens, the telescopic valve B92 moves from the contracted state to the extended state, the short section C93 and the short section B62 are connected, the pneumatic slide gate valve B91 opens, and then the electric butterfly valve 61A opens. The material enters the finished material bin from the drum body 2. When the material in the finished material bin reaches a certain position, the electric butterfly valve 61A closes, the pneumatic slide gate valve B91 closes, the telescopic valve B92 moves from the extended state to the contracted state, the short section C93 and the short section B62 separate, and the cover valve B95 closes. At this time, the drum body 2 has completed the discharge and rotates to the upward position to enter the replenishment state. This process is repeated to achieve the effect of automatic replenishment and discharge, which improves production efficiency.

[0026] During the feeding and discharging process, when the pneumatic slide gate valve A71 or pneumatic slide gate valve B91 is working, it will pull the rack 84 to drive the gear 83 to rotate, which in turn will drive the elliptical plates 85 at both ends of the shaft 82 to rotate. The slide bar 86 will make linear reciprocating motion as the elliptical plates 85 rotate, which will drive the push rod 87 to move. Since the push rod 87 is limited by the limiting rod 88, it can only make linear motion, which will drive the push rod 87 to collide with the device to generate vibration, promote the discharge of materials, and avoid blockage due to friction.

[0027] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
