Description

Technical Field

[0001] The present application relates to the technical field of cement production, and in particular to a multi-batch sampling device for cement raw materials. Background Art

[0002] Cement raw materials need to be collected regularly or samples need to be collected continuously within a unit time for testing. A spiral feed pipe is set on one side of the cement raw material discharge pipe. One end of the spiral feed pipe extends into the discharge pipe, and an opening is set upward at one end of the spiral feed pipe. A drop pipe is set at the bottom of the external side of the spiral feed pipe. When sampling is required, the spiral feed pipe is started, and the material falls into the sampling tray through the drop pipe.

[0003] In the existing technology, cement raw material sampling equipment can only place one sampling tank at a time. The sampling tank needs to be replaced after sampling is completed. Therefore, the sampling tank needs to be replaced manually at regular intervals. Otherwise, the two samples will be mixed in the same sampling tank, resulting in inaccurate sample data monitoring. In addition, the sampling tank needs to be replaced manually at regular intervals, which is very inconvenient. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will describe in detail the embodiments of the technical solution of the present application in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only used as examples and cannot be used to limit the scope of protection of the present application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the present application; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present application; the terms "including" and "having" in the specification and claims of the present application and the above-mentioned description of the drawings and any variations thereof are intended to cover non-exclusive inclusions.

[0021] Specifically, please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the overall structure of a multi-batch sampling device for cement raw materials provided in an embodiment of the present application. Figure 2 for Figure 1 The enlarged view at point A, Figure 3 This is a schematic diagram of a partial top view of the connection disk provided in an embodiment of the present application. Figure 4A schematic diagram of the partial structure of the receiving bucket and sampling cup provided in an embodiment of the present application. The multi-batch sampling device 100 for cement raw materials includes a screw conveyor 120 fixed by a frame 110. A sampling valve 121 is provided on one side of the bottom of the screw conveyor 120. In the embodiment of the present application, the screw conveyor 120 is used to convey cement raw materials. The screw conveyor 120 and the sampling valve 121 are both prior art and will not be described in detail here. The bottom of the sampling valve 121 is connected to a sampling tube 130. The sampling tube 130 is a corrugated tube. The other end of the sampling tube 130 is connected to a discharge barrel 131. When the sampling valve 121 is opened, the cement raw materials inside the screw conveyor 120 will fall into the discharge barrel 131 through the sampling tube 130 under the action of gravity, and then fall into the corresponding sampling cup 153 through the discharge barrel 131. The discharge barrel 131 is provided through the frame 110 and is connected to a vibration motor 140. The vibration motor 140 is used to turn on after a sampling is completed, thereby driving the discharge barrel 131 and the sampling tube 130 to vibrate, thereby removing any remaining cement raw materials remaining in the sampling tube 130 and the discharge barrel 131. The frame 110 is also provided with a turntable component 150. The turntable component 150 includes a connecting disk 151. The connecting disk 151 has a plurality of cylindrical receiving buckets 152 arranged in a circular array on the outer circumference. The receiving buckets 152 and the connecting disk 151 can be integrally formed to ensure the stability of their connection. The number of connecting disks 151 can be set according to actual conditions, and 4-6 is generally the best. A sampling cup 153 is placed on the receiving bucket 152, which is used to hold the sample. The top of the connecting disk 151 is coaxially connected to a rotating rod 154, and the other end of the rotating rod 154 extends upward to the top of the frame 110 and is connected to a rotating motor 155. The rotating motor 155 can drive the connecting disk 151 to rotate through the rotating rod 154, thereby exchanging the positions of the receiving buckets 152. When the sample on one of the receiving buckets 152 is sampled, the rotating motor 155 drives the connecting disk 151 to rotate, thereby exchanging the positions of the receiving buckets 152, so that the next receiving bucket 152 rotates to the bottom of the discharge cylinder 131. The rotating motor 155 is fixed to the frame 110. A support column 156 is provided at the bottom projection of the connecting disk 151. The top of the support column 156 is connected to the bottom of the connecting disk 151 through a rotating support seat 157. The support column 156 is used to support the connecting disk 151 and maintain the structural stability of the connecting disk 151 under a load state.

[0022] As can be seen from the above, in the embodiment of the present application, by providing a turntable component 150, the turntable component 150 includes a connecting disk 151 and multiple receiving buckets 152, and the connecting disk 151 is driven by a rotating motor 155. Sampling cups 153 for sampling are placed on the receiving buckets 152. Therefore, in the embodiment of the present application, multiple sampling cups 153 can be placed in each receiving bucket 152 at the same time. Each sampling cup 153 will be driven by the rotating motor 155 to rotate to the bottom of the discharge barrel 131, and then can respectively receive cement raw material samples from the discharge barrel 131. The operator changes from the original one-at-a-time working mode to the multiple-at-a-time working mode, which can effectively extend the interval between the operator's operations and the operator does not need to frequently change the sampling cups 153. On the other hand, by providing a vibration motor 140, the present application can discharge the material remaining in the sampling tube 130 as cleanly as possible, avoiding large contamination between samples.

[0023] In some embodiments, four vertically extending retaining grooves 152a are provided on the inner wall of the receiving bucket 152, and four slide rails 153a that match the retaining grooves 152a are provided on the outer wall of the sampling cup 153. In this embodiment of the present application, the aforementioned arrangement effectively limits the horizontal rotation of the sampling cup 153 through the restraining cooperation between the retaining grooves 152a and the slide rails 153a, thereby facilitating the stability of the sampling cup 153 even when the receiving bucket 152 rotates.

[0024] In some embodiments, at least one of the slide rails 153a on the sampling cup 153 is shaped like a U-shaped rail, so that the operator can easily lift the sampling cup 153 via the U-shaped rail 153a. The corresponding limiting groove 152a on the receiving bucket 152, which corresponds to the U-shaped rail 153a, is a through groove that runs through the inside and outside of the receiving bucket 152. In this embodiment of the present application, through this arrangement, the operator can insert his hand through the U-shaped rail 153a, thereby conveniently lifting the sampling cup 153. Furthermore, in this embodiment of the present application, the limiting groove 152a corresponding to the U-shaped rail 153a is a through groove that runs through the inside and outside of the receiving bucket 152. Therefore, when the sampling cup 153 is inserted into the receiving bucket 152, the U-shaped rail 153a will extend through the through groove to the outside of the receiving bucket 152.

[0025] In some embodiments, a lifting member 160 (the lifting member 160 is not shown in the figure) is provided at the bottom orthographic projection of the discharge barrel 131 below one of the receiving buckets 152. The lifting member 160 includes a cylinder component 162 fixed by a fixing member 161. A reserved hole for the rod head of the cylinder component 162 to extend into the receiving bucket 152 is provided at the bottom wall of the receiving bucket 152. In the embodiment of the present application, through the above arrangement, when sampling is required, the cylinder component 162 will extend, and the rod head of the cylinder component 162 will extend into the receiving bucket 152 along the reserved hole, and further lift the sampling cup 153 in the receiving bucket 152, so that the top wall of the sampling cup 153 is tightly attached to the bottom of the frame 110, thereby avoiding the phenomenon of material leakage and spillage caused by a certain gap between the discharge barrel 131 and the sampling cup 153.

[0026] In some embodiments, an annular buffer rubber ring 153b is provided at the port at one end of the top of the sampling cup 153. The inner diameter of the buffer rubber ring 153b is larger than the outer diameter of the discharge barrel 131. In the embodiment of the present application, through the above arrangement, when the sample is lifted by the cylinder component 162, the sampling cup 153 will be closely attached to the bottom of the frame 110, and the sampling cup 153 will wrap the bottom end of the discharge barrel 131, thereby further preventing leakage and spillage of the material.

[0027] In some embodiments, a PLC control box is included, the rotating motor 155 is a servo motor, and the PLC control box is electrically connected to the rotating motor 155, the sampling valve 121, and the cylinder component 162. In the embodiment of the present application, by providing a PLC control box, the PLC control box can control the synchronous operation of the rotating motor 155, the sampling valve 121, and the cylinder component 162, further improving the degree of automation of the present application.
