Referring to fig. 1 to 3, in an embodiment, a calcium nitrate reaction apparatus 10 for conveniently monitoring a reaction process includes a reaction tank 100 and a solid-liquid boundary position detecting assembly 200, wherein a stone material feeding pipe 110 and a gas phase discharging pipe 120 are disposed at a top of the reaction tank 100, a calcium nitrate solution overflow pipe 130 is disposed at an upper portion of a sidewall, and a nitric acid feeding distributor 140 is disposed at a bottom of the sidewall. The solid-liquid boundary position detecting assembly 200 includes a weight 210, a winch 220, a steering pulley block 230 and a traction rope 240, the weight 210 is disposed in the reaction tank 100, the winch 220 is installed on the outer wall of the reaction tank 100, the steering pulley block 230 is fixed on the tank top of the reaction tank 100, one end of the traction rope 240 is connected to the weight 210, and the other end of the traction rope passes through the tank top of the reaction tank 100, is erected on the steering pulley block 230, and is wound on the winch 220. The winch 220 is rotated, and the traction rope 240 can be wound on the winch 220 or released from the winch 220, so that the weight 210 is lifted in a vertical direction.
The solid-liquid boundary position detection assembly 200 comprising a heavy hammer 210, a winch 220, a steering pulley block 230 and a traction rope 240 is arranged on the reaction tank 100, the winch 220 is rotated to release the traction rope 240 in the contact reaction process of stone and calcium nitrate, the heavy hammer 210 descends along the vertical direction under the steering action of the steering pulley block 230 until the lower surface of the heavy hammer 210 is in contact with the surface of the stone, the heavy hammer 210 stops descending, and at the moment, the stone level in the reaction tank 100 can be visually acquired through the displacement of the traction rope 240 relative to the winch 220. As the stone material level descends along with the reaction, the weight 210 descends along with the stone material level, tracks and detects the current stone material level, monitors the reaction process, and provides effective data support for selection of stone material replenishment opportunity. Secondly, solid-liquid boundary position detection subassembly 200 simple structure measures accurately, and is not fragile, compares that current level gauge or charge level indicator have unique advantage.
In one embodiment, in order to visually observe the boundary position between the rock and the calcium nitrate solution, a dial 150 is disposed on the outer wall of the reaction tank 100, an indicator pin 160 is disposed at an end of the pulling rope 240 close to the winch 220, and an orthographic projection of the indicator pin 160 can coincide with the dial 150. For example, when the reaction tank 100 is filled with stone, the winch 220 is rotated to wind the traction rope 240 around the winch 220 and the weight 210 is located at the highest point, and at this time, the orthographic projection of the pointer 160 is located at the lower end of the scale 150, that is, at the highest point of the solid-liquid separation. After the stone loading is completed, the weight 210 is naturally dropped, and the pointer 160 moves upward. When the weight 210 contacts the solid-liquid boundary position, the weight stops falling, and at this time, the displacement of the pulling rope 240 relative to the capstan 220, that is, the relative displacement of the pointer 160, is the current solid-liquid boundary position. As the solid-liquid reaction proceeds, the stone is consumed, the solid-liquid boundary position moves downward, the weight 210 moves downward, and the pointer 160 moves upward to obtain the solid-liquid boundary position in the reaction process in real time.
In a preferred embodiment, the diverting pulley assembly 230 includes at least one fixed pulley 231 and a pulley mounting seat 232 arranged side by side, the pulley mounting seat 232 is fixed on the tank top of the reaction tank 100, and the fixed pulley 231 is mounted in the pulley mounting seat 232.

In one embodiment, the area of the lower surface of the weight 210 is not less than 50cm2So that the heavy punch 210 can be stably contacted with the upper surface of the stone, the measurement error caused by local protrusion or depression of the upper surface of the stone is reduced, and the accuracy of the measurement of the solid-liquid boundary position is improved.
In another embodiment, a lock 221 is disposed on the winch 220, and in the measuring state, the lock 221 is opened, and the winch 220 rotates to enable the weight 210 to fall normally. When the stone is fed, the weight 210 is lifted to the highest point, and the winch 220 is locked by the locking piece 221, so that the weight 210 is prevented from being pressed to the bottom of the stone in the stone feeding process.
Further, a return member is disposed on the winch 220, and the return member provides a return force to allow the pulling rope 240 to wind on the winch 220. The restoring force provided by the restoring member is smaller than the difference between the gravity of the weight 210 and the buoyancy of the weight 210 in the calcium nitrate solution.
Referring also to fig. 4, in one embodiment, the nitric acid feed distributor 140 is cross-shaped to facilitate uniform feeding and reduce pressure of the rock material on the nitric acid feed distributor 140, extending the life of the nitric acid feed distributor 140. A plurality of nitric acid distribution holes 141 are formed below the nitric acid feeding distributor 140, so that the nitric acid feeding is smoother.
In another embodiment, the calcium nitrate solution overflow pipe 130 is a square pipe, so that after a long time of operation, slag deposited on the bottom of the square pipe can be cleaned, and the probability of blockage of the calcium nitrate solution overflow pipe 130 can be reduced.
