Description

Technical Field

[0001] This utility model relates to a testing device, specifically a testing device for coal quality testing, belonging to the field of coal quality testing technology. Background Technology

[0002] The intelligent integrated muffle furnace features a precise temperature control system and high-precision thermocouples, ensuring the stability and uniformity of the furnace temperature, which is crucial for accurate coal ash content detection. In coal ash content testing, the coal sample needs to be burned at high temperature to constant weight to determine its ash content. The intelligent integrated muffle furnace provides the necessary high-temperature environment and ensures the stability and consistency of the coal sample during the burning process by precisely controlling the heating rate and temperature, thereby improving the accuracy and reliability of the test results.

[0003] However, when using existing muffle furnaces, the ash dish containing the coal sample is placed into the furnace for heating. After the coal sample is ashed, the ash dish needs to be removed. Since the ash dish is extremely hot when it is taken out, if the operator does not hold the ash dish correctly or does not hold it with enough force, the ash dish may fall during the movement, which can easily cause burns. Utility Model Content

[0004] The purpose of this utility model is to provide a testing device for coal quality testing in order to solve the above problems. By rotating the stop bar with pliers, the tray can drive the support base to rotate, thereby causing the rotating block to rotate within the mounting block. When the tray rotates to the state of being connected to the furnace body, it is convenient for the operator to move the ash dish rack into the tray.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a coal quality testing device, comprising a furnace body, a main structure fixedly installed on the furnace body, a rotating mechanism installed on the furnace body, the rotating mechanism comprising a rotating block and a mounting block, a mounting block fixedly connected to the side wall of the furnace body, a rotating block rotatably connected to the mounting block, a support base fixedly installed on the rotating block, a protrusion and a tray fixedly connected to the support base, a stop bar fixedly installed on the tray, and a storage mechanism installed on the tray.

[0006] Preferably, the protrusion is located at the top of the support base, and the tray is located on the side of the support base opposite to the rotating block.

[0007] Preferably, the top of the protrusion is cylindrical and the bottom of the protrusion is cubic.

[0008] Preferably, the storage mechanism includes a support frame and ash dishes. The support frame is placed on the top of the tray, and a plurality of ash dishes are engaged and installed on the support frame. The ash dishes are fixedly connected to a locking block and a support rod, and a connecting rod is fixedly installed on the support frame.

[0009] Preferably, the support frame is located at the top of the tray, and the two connecting rods are symmetrically installed on both sides of the support frame.

[0010] Preferably, the part of the card block that contacts the support frame is arranged with an arc surface structure, and the two card blocks are symmetrically arranged on both sides of the ash dish.

[0011] Preferably, the support rod contacts the top of the support frame, and the support rod is arranged in an arc shape.

[0012] Preferably, the main structure includes a furnace door and a handle. The furnace door is rotatably mounted on the furnace body, and the handle is fixedly connected to the furnace door. The furnace body is provided with a furnace cavity, and a pad is installed in the furnace cavity.

[0013] Preferably, the pad is fixedly connected to the furnace body, and the pad and the tray are on the same horizontal plane.

[0014] The beneficial effects of this utility model are as follows: After the coal sample is ashed, the furnace body is opened to make it open. Then, the operator can pull the stop bar with pliers. The stop bar is installed on the top of the tray. The stop bar drives the support seat fixed on the tray to rotate, which can make the rotating block fixed on one side of the support seat rotate inside the mounting block. The mounting block is fixed to the side wall of the furnace body. When the tray rotates to a state where it is in communication with the inside of the furnace body, the ash dish placement rack can be pulled to the top of the tray. Then, the stop bar is slowly rotated, which can make the support seat drive the tray to return to its original position. In this way, while the ash dish placement rack is cooled at the top of the tray, it can also prevent burns to the hands caused by improper manual handling of ash dishes. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 As shown, a coal quality testing device includes a furnace body 1, a main structure 2 fixedly installed on the furnace body 1, a rotating mechanism 3 installed on the furnace body 1, the rotating mechanism 3 including a rotating block 305 and a mounting block 306, the mounting block 306 fixedly connected to the side wall of the furnace body 1, the rotating block 305 rotatably connected to the mounting block 306, a support base 303 fixedly installed on the rotating block 305, a protrusion 304 and a tray 301 fixedly connected to the support base 303, a stop bar 302 fixedly installed on the tray 301, and a storage mechanism 4 installed on the tray 301.

[0024] As a technical optimization of this utility model, the protrusion 304 is located at the top of the support base 303, and the tray 301 is located on the side of the support base 303 away from the rotating block 305. When the tray 301 is rotated to be aligned with the pad 203, the support frame 401 can be pulled and placed on top of the tray 301.

[0025] As a technical optimization of this utility model, the top of the protrusion 304 is cylindrical and the bottom of the protrusion 304 is cubic. The protrusion 304 is designed to facilitate the operator to rotate the support base 303.

[0026] As a technical optimization of this utility model, the storage mechanism 4 includes a support frame 401 and ash dishes 402. The support frame 401 is placed on the top of the tray 301. Several ash dishes 402 are engaged and installed on the support frame 401. A locking block 403 and a support rod 405 are fixedly connected to the ash dishes 402. A connecting rod 404 is fixedly installed on the support frame 401. When the locking block 403 contacts the support frame 401, it can limit the ash dishes 402.

[0027] As a technical optimization of this utility model, the support frame 401 is located at the top of the tray 301, and the two connecting rods 404 are symmetrically installed on both sides of the support frame 401. The connecting rods 404 facilitate the operator to place the support frame 401.

[0028] As a technical optimization of this utility model, the part of the card block 403 that contacts the support frame 401 is set with an arc surface structure, and the two card blocks 403 are symmetrically arranged on both sides of the ash dish 402. Through the card blocks 403, it is easy to place the ash dish 402 into the through groove provided in the support frame 401.

[0029] As a technical optimization of this utility model, the support rod 405 contacts the top of the support frame 401, and the support rod 405 is arranged in an arc shape. The support rod 405 supports the ash dish 402, which makes it convenient for the operator to disassemble the ash dish 402.

[0030] As a technical optimization of this utility model, the main body 2 includes a furnace door 201 and a handle 202. The furnace door 201 is rotatably installed on the furnace body 1, and the handle 202 is fixedly connected to the furnace door 201. The furnace body 1 is provided with a furnace cavity 204, and a pad 203 is installed in the furnace cavity 204. When the support frame 401 is placed on the pad 203, the coal sample in the ash dish 402 can be heated through the furnace body 1.

[0031] As a technical optimization of this utility model, the pad 203 is fixedly connected to the furnace body 1, and the pad 203 and the tray 301 are on the same horizontal plane. The support frame 401 can be moved by pulling it from the pad 203 onto the tray 301.

[0032] In use, the operator first weighs the coal sample and spreads it evenly in the ash pan 402. Then, by clamping the support rod 405 fixed on one side of the ash pan 402, the operator can move the ash pan 402 to the through hole provided in the support frame 401. Since there are locking blocks 403 installed on both sides of the ash pan 402, when the locking blocks 403 contact the side wall of the support frame 401, they can support the ash pan 402, thereby limiting the ash pan 402 within the support frame 401. Next, by using the connecting rods 404 installed at both ends of the support frame 401, the support frame 401 can be placed on top of the tray 301. After the furnace body 1 is preheated to the predetermined temperature and maintained for a period of time to ensure uniform temperature inside the furnace, the furnace door 201 is opened. The stop rod 302, which is installed on top of the tray 301, is pulled by pliers. The stop rod 302 drives the support seat 303 fixed on the tray 301 to rotate. The rotating block 305, fixed on one side of the support base 303, rotates within the mounting block 306, which is fixed to the side wall of the furnace body 1. When the tray 301 rotates to a state where it is in communication with the interior of the furnace body 1, the support frame 401 can be pulled from the tray 301 into the furnace cavity 204. First, place the ash dish 402 at a low temperature. After the coal sample begins to ashing, push it into the hot part of the furnace. Then, close the furnace door 201 and start timing. After the coal sample ashing, turn off the power to the furnace body 1, open the furnace door 201, and put the furnace body 1 in an open state. Then, pull the support frame 401 onto the tray 301. Next, slowly rotate the stop bar 302, which can cause the support base 303 to drive the tray 301 back to its original position. This allows the support frame 401 to cool at the top of the tray 301 while also preventing burns to the hands caused by improper manual handling of the ash dish 402. Finally, after the ash dish 402 cools to room temperature, weigh it and record the mass.
