Description

Technical Field

[0001] This utility model relates to the field of coal powder sampling technology, specifically to a constant velocity continuous coal powder sampler. Background Technology

[0002] Pulverized coal is a black powdery fuel composed of fine coal particles with a particle size of less than 0.5 mm. It is widely used in industrial fields, especially in thermal power generation, steel smelting, and building materials production.

[0003] Before use, pulverized coal needs to be stored in a storage container. During storage, sampling and testing of the pulverized coal are required, necessitating the use of a sampler. Most existing samplers are simple sampling tubes, which are installed through pre-drilled holes in the storage container. Sampling is achieved by opening the sampling tube. However, this method is prone to clogging the pipes with pulverized coal, making continuous sampling inconvenient. Therefore, we propose a constant-velocity continuous pulverized coal sampler. Utility Model Content

[0004] The purpose of this invention is to provide a constant velocity continuous coal powder sampler, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a constant velocity continuous coal powder sampler, comprising a support plate, a sampling tube fixedly installed on one side wall of the support plate, a first electric push rod fixedly installed on the other side of the support plate, the push rod of the first electric push rod movably passing through the support plate and fixedly connected to a sliding block, the sliding block sliding in the inner cavity of the sampling tube, a cone head fixedly connected to one side wall of the sliding block via a connecting rod, and a conduit fixedly connected to the bottom of the sampling tube;

[0006] An adjusting plate is fixedly connected to the tail end of the support plate. A strip groove is provided on the top of the adjusting plate. A movable plate is provided in the inner cavity of the strip groove. Multiple evenly distributed lifting components are installed on the top of the movable plate. A sampling container is provided on the lifting component. The lifting component is used to drive the sampling container to rise and fall.

[0007] By adopting the above technical solution, the movable plate is first moved, thereby moving the sampling container accordingly. Then, the lifting component lifts the corresponding sampling container, aligning it with the guide tube. Next, the first electric push rod moves the sliding block, pushing the cone into the storage container. Then, pulling back the cone can carry the coal powder into the sampling tube, allowing the coal powder to be discharged along the guide tube into the sampling container, thus achieving single sampling. When the cone is inserted into the storage container again, the sampling container is simultaneously reset, and the movable plate is moved to align another sampling container with the guide tube, thus performing sampling again. This achieves continuous sampling at a constant speed, which helps to improve sampling efficiency.

[0008] In a preferred embodiment of this utility model, a sliding cavity is provided at the bottom of the inner cavity of the strip groove. A lead screw motor is fixedly installed on one end face of the inner cavity of the sliding cavity. A lead screw is fixedly connected to the outer end of the drive shaft of the lead screw motor. The outer end of the lead screw is rotatably connected to the inner wall of the sliding cavity. A suitable lead screw slider is fitted on the outer wall of the lead screw. The top of the lead screw slider is fixedly connected to the movable plate.

[0009] By adopting the above technical solution, the lead screw motor can drive the lead screw to rotate, thereby driving the lead screw slider to move, which in turn drives the movable plate to move, thereby moving the sampling container and thus realizing the replacement of the sampling container.

[0010] In a preferred embodiment of the present invention, the lifting assembly includes a fixing block, which is fixed to the top of the movable plate. A second electric push rod is embedded in the middle of the top of the fixing block. A carrier block is fixedly connected to the outer end of the push rod of the second electric push rod. A placement groove is provided on the top of the carrier block, and the sampling container is placed in the placement groove.

[0011] By adopting the above technical solution, the second electric actuator can drive the carrier block to rise, thereby driving the sampling container to rise and fit against the bottom of the conduit, so that the coal powder can be accurately introduced into the sampling container, which helps to avoid coal powder overflow.

[0012] In a preferred embodiment of this utility model, limiting rods are fixedly connected to both sides of the bottom of the carrier block, and the limiting rods are movably inserted into the limiting grooves opened on the top of the fixed block.

[0013] In a preferred embodiment of this utility model, a magnet plate is fixedly installed at the bottom of the inner cavity of the placement groove, and an iron sheet is fixedly connected to the bottom of the sampling container.

[0014] In a preferred embodiment of this utility model, a flange is fixedly connected to the outer end face of the sampling tube.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The present application provides a constant-velocity continuous coal powder sampler. A first electric actuator drives a cone head to be inserted into a storage container, allowing coal powder to move to one side of the cone head. Pulling back the cone head allows the coal powder to be carried into a sampling tube and then into a sampling container along the guide tube. When the cone head extends again, a movable plate moves to align another sampling container with the guide tube, allowing the cone head to be pulled back again for sampling. This enables constant-velocity continuous multiple sampling, which helps to improve sampling efficiency.

[0017] The second electric actuator lifts the platform, allowing the sampling container to fit against the bottom of the conduit, thus ensuring accurate connection and receiving of pulverized coal. This helps prevent pulverized coal from overflowing and causing waste after sampling. Attached Figure Description

[0027] Please see Figure 1-3 This utility model provides a technical solution: a constant velocity continuous coal powder sampler, including a support plate 1, a sampling tube 11 fixedly installed on one side wall of the support plate 1, a first electric push rod 12 fixedly installed on the other side of the support plate 1, the push rod of the first electric push rod 12 movably passes through the support plate 1 and is fixedly connected to a sliding block 15, the sliding block 15 slides in the inner cavity of the sampling tube 11, a cone head 13 is fixedly connected to one side wall of the sliding block 15 through a connecting rod 16, and a conduit 17 is fixedly connected to the bottom of the sampling tube 11;

[0028] An adjusting plate 2 is fixedly connected to the tail end of the support plate 1. A strip groove 21 is provided on the top of the adjusting plate 2. A movable plate 22 is provided in the inner cavity of the strip groove 21. Multiple evenly distributed lifting components are installed on the top of the movable plate 22. A sampling container 32 is provided on the lifting component. The lifting component is used to drive the sampling container 32 to rise and fall.

[0029] It should be understood that, firstly, the movable plate 22 moves, thereby moving the sampling container 32 accordingly. Then, the lifting component lifts the corresponding sampling container 32, thereby aligning it with the guide tube 17. Then, the first electric push rod 12 moves the sliding block 15, thereby pushing the cone 13 into the storage container. Then, pulling back the cone 13 can carry the coal powder into the sampling tube 11, so that the coal powder can be discharged along the guide tube 17 into the sampling container 32, thereby achieving single sampling. When the cone 13 is inserted into the storage container again, the sampling container 32 is reset simultaneously, and the movable plate 22 is moved to align another sampling container 32 with the guide tube 17, thereby performing sampling again, thus achieving continuous sampling at the same speed, which is beneficial to improving sampling efficiency.

[0030] Furthermore, a flange 14 is fixedly connected to the outer end face of the sampling tube 11. The flange 14 facilitates the installation and fixation of the entire device and the storage container.

[0031] like Figure 1 and 2 As shown in Figure 3; a sliding cavity is provided at the bottom of the inner cavity of the strip groove 21. A lead screw motor 25 is fixedly installed on one end face of the inner cavity of the sliding cavity. A lead screw 23 is fixedly connected to the outer end of the drive shaft of the lead screw motor 25. The outer end of the lead screw 23 is rotatably connected to the inner wall of the sliding cavity. A suitable lead screw slider 24 is fitted on the outer wall of the lead screw 23. The top of the lead screw slider 24 is fixedly connected to the movable plate 22.

[0032] It should be understood that the lead screw motor 25 can drive the lead screw 23 to rotate, thereby driving the lead screw slider 24 to move, which in turn drives the movable plate 22 to move, thereby moving the sampling container 32 to replace the sampling container 32.

[0033] like Figure 1 and 2 As shown in Figure 4, the lifting assembly includes a fixed block 3, which is fixed to the top of the movable plate 22. A second electric push rod 34 is embedded in the middle of the top of the fixed block 3. The outer end of the push rod of the second electric push rod 34 is fixedly connected to a carrier block 31. A placement groove is opened on the top of the carrier block 31, and the sampling container 32 is placed in the placement groove.

[0034] It should be understood that the second electric actuator 34 can drive the carrier block 31 to rise, thereby driving the sampling container 32 to rise and fit against the bottom of the conduit 17, so that the coal powder can be accurately introduced into the sampling container 32, which helps to avoid coal powder overflow.

[0035] Furthermore, limit rods 35 are fixedly connected to both sides of the bottom of the carrier block 31. The limit rods 35 are movably inserted into the limit groove opened on the top of the fixed block 3, thereby improving the stability of the carrier block 31 during lifting and lowering.

[0036] Furthermore, a magnet plate 33 is fixedly installed at the bottom of the inner cavity of the placement tank, and an iron sheet is fixedly connected to the bottom of the sampling container 32.

[0037] It should be understood that when the sampling container 32 is placed in the placement slot, it can be connected by magnetic adsorption, thereby making the sampling container 32 highly stable.
