[0027] like Figure 1As shown, a slag discharge device for a chloride titanium dioxide slurry furnace comprises a booster screw 1 and a long-rod pneumatic valve arranged at the bottom row of the slurry furnace stirring. The booster screw 1 is used for conveying according to a predetermined route and preventing blockage. The booster screw 1 is arranged above the long-rod pneumatic valve. A driving shaft 3 that rotates synchronously with the booster screw 1 is passed through the middle of the booster screw 1. The long-rod pneumatic valve is arranged at the discharge port 5 at the bottom of the slurry furnace, fixedly connected to the cylinder 6, and has a gap with the booster screw 1. The booster screw 1 is connected to the driving shaft 3 and rotates with the driving shaft 3. The driving shaft 3 can be driven to rotate by setting a driving mechanism such as a motor, or the driving shaft 3 can be connected to the stirring shaft in the slurry furnace and rotate with the stirring shaft.

[0028] In the slag discharge device for the titanium dioxide chloride slurry furnace according to the embodiment of the utility model, the device is composed of a booster spiral part 1 and a long-rod pneumatic valve arranged in sequence from top to bottom on the stirring bottom row of the slurry furnace, and mechanical slag discharge is achieved through the cooperation of the two.

[0029] The slurry furnace stirring bottom row is a device for slag discharge arranged at the bottom of the slurry furnace stirring part. The present application is arranged at the bottom row.

[0030] In some specific embodiments, the long-stem pneumatic valve is a long-stem pneumatic C-type valve 2. The long-stem design makes the valve switch state more intuitive, and the operator can clearly see the valve opening at a distance from the valve, thereby improving the convenience and safety of operation. Due to its special valve body design, the C-type valve can accurately control the flow rate in a wide range, especially in low flow areas, which is particularly important for slag discharge processes that require accurate flow control.

[0031] In some specific embodiments, the booster spiral portion 1 is a spiral belt, that is, a spiral conveyor belt. The waste slag generated in the slurry furnace 4 is transported by the spiral belt, and the drive shaft 3 drives the spiral belt to rotate synchronously, so as to realize continuous transportation of the waste slag. During vertical transportation, due to the continuous rotation of the spiral belt on the shaft, efficient transportation can be achieved at low energy consumption. The structure of the spiral belt is relatively simple, and key components such as the spiral and bearings are easy to inspect and replace, and maintenance is convenient. By adjusting the rotation speed of the spiral, the conveying volume can also be conveniently adjusted to meet different production needs. Compared with other conveying methods, spiral belt conveying causes less damage to the material.

[0032] Based on the above embodiment, the gap between the bottom of the booster spiral 1 and the long-rod pneumatic C-type valve 2 is 15-20 mm. The C-type valve is an air-open valve. In order to prevent the C-type valve from automatically opening after a failure, causing material leakage in the slurry furnace 4 and causing safety and environmental accidents, it is necessary to ensure that the gap between the bottom of the booster spiral 1 and the sealing surface of the C-type valve is 15 mm to 20 mm during installation.

[0033] In some specific embodiments, flanges are provided on the upper and lower sides of the long-stem pneumatic C-type valve 2. The flanges are provided so that the C-type valve can be quickly and conveniently connected and disassembled, which is convenient for early installation, later maintenance and replacement. Preferably, in order to provide good sealing performance for the flange connection, a gasket of appropriate size can be added at the connection to prevent material leakage. The flange connection also makes the device more convenient when pressure testing or leakage inspection is required, and the connection point can be quickly inspected.

[0034] On the basis of the above embodiment, the long-stem pneumatic C-type valve 2 is a detachable structure. The detachable structure can be easily disassembled and reassembled. This greatly simplifies maintenance and repair work and reduces downtime caused by failures. When the C-type valve is damaged, only the damaged part needs to be replaced, thereby reducing costs and maintenance expenses.

[0035] In some specific embodiments, the surfaces of the booster spiral 1 and the long-rod pneumatic C-type valve 2 have high-temperature resistant components. The slag discharge process of the slurry furnace 4 is a high-temperature operation. In order to ensure that the booster spiral 1 and the long-rod pneumatic C-type valve 2 will not be damaged or reduce the probability of damage when working in a high-temperature environment for a long time, high-temperature resistant components are provided on the surfaces of the booster spiral 1 and the long-rod pneumatic C-type valve 2, so that they can maintain structural integrity and functionality, and can also reduce unplanned downtime caused by failures and improve production efficiency.

[0036] On the basis of the above embodiment, a flow meter is provided on the long-stem pneumatic C-type valve 2. The setting of the flow meter can provide real-time flow data, so that the operator can understand the flow of materials through the C-type valve at any time. The integration of the flow meter enables the C-type valve to not only switch the fluid, but also accurately adjust the flow, thereby achieving more accurate process control.

[0037] In some specific embodiments, in order to reduce the adhesion of waste residue on the surface of the C-type valve, the surface of the booster spiral 1 and the long-rod pneumatic C-type valve 2 has an anti-stick coating, thereby reducing the risk of scaling and agglomeration and maintaining the cleanliness and functionality of the C-type valve. The coating can also protect the C-type valve from corrosion and wear, extend its service life, and reduce replacement frequency and related costs.

[0038] On the basis of the above embodiment, a PLC controller is further included, which is connected to the long-stem pneumatic C-type valve 2 for controlling the start and stop of the slag discharge process. The PLC controller is set to realize automatic start and stop of the device without manual intervention, thereby improving work efficiency and avoiding the risk of operators contacting high-temperature harmful substances, thereby improving the work safety of operators.

[0039] On the basis of the above embodiment, a collection pool is provided below the slurry furnace bottom discharge port 5. The collection pool can collect the waste discharged from the slurry furnace bottom discharge port 5, which is convenient for subsequent treatment and disposal, improves the treatment efficiency, and can also effectively prevent direct discharge into the environment, reducing pollution to the surrounding environment. The waste slag discharged from the slurry furnace 4 contains recyclable materials, and the collection pool can be used as a place for preliminary separation and recycling to improve the recovery rate of resources.

[0040] The utility model has at least the following advantages:

[0041] (1) The booster screw 1 is used as a conveying mechanism to move the waste slag from the place where it is generated to the place where it is collected or processed. When used in conjunction with the long-stem pneumatic C-type valve 2, it can achieve rapid and continuous slag removal operations.

[0042] (2) The long-stem pneumatic C-type valve 2 can accurately control the opening and closing time, thereby adjusting the speed and amount of slag discharge to ensure that the slag discharge process meets the process requirements.

[0043] (3) The continuous rotation of the booster spiral 1 can prevent slag from accumulating in the slag discharge channel, while the fast response capability of the long-stem pneumatic C-type valve 2 can cut off the slag flow in time to avoid blockage.

[0044] (4) The long-stem pneumatic C-type valve 2 can be remotely controlled through signals, and combined with the automatic control system, it can realize unattended automatic slag discharge.

[0045] (5) The quick shut-off capability of the long-stem pneumatic C-type valve 2 can quickly stop slag discharge in an emergency, reducing safety risks. At the same time, the closed conveying of the spiral reduces the spread of dust and harmful gases during the slag discharge process.

[0046] (6) The design of the booster spiral portion 1 and the long-stem pneumatic C-type valve 2 can reduce equipment damage caused by slag accumulation and blockage, thereby reducing maintenance work and related costs.

[0047] (7) By precisely controlling the slag discharge process, energy consumption and environmental pollution can be reduced, meeting the requirements of sustainable development.
