Description

Technical Field

[0001] This utility model relates to an apparatus for producing ferric phosphate, and more particularly to a protective device for the preparation of ferric phosphate. Background Technology

[0002] Iron phosphate is an important precursor material for the preparation of lithium iron phosphate, and its product quality directly affects the quality of lithium iron phosphate. In the wet synthesis process of iron phosphate, a plate and frame filter press is used for filtration. The filtered material is unloaded by the filter press discharge device and then transferred to a belt conveyor, which then transports it to a pulping tank for pulping.

[0003] Chinese patent application CN202322263905.5 discloses a protective device for ferric phosphate, which facilitates observation of the ferric phosphate product during the transport of the filter cake from the plate and frame filter press to the flash drying stage. The device is easy to disassemble and clean. However, this device only protects the ferric phosphate conveyor belt and does not protect the material falling from the filter press onto the belt, which can easily lead to a decrease in the quality of the finished product. At the same time, the impact force when the material falls from the filter press can easily cause material splashing, making manual cleaning difficult. Summary of the Invention

[0004] Purpose of the utility model: The purpose of this utility model is to provide a protective device for the preparation of ferric phosphate that protects the feed port of a filter press to the pulping tank, reduces the introduction of foreign objects, and prevents material splashing.

[0005] Technical solution: The protective device for the preparation of ferric phosphate according to this utility model includes a filter press, a conveying mechanism located below the filter press for conveying materials, a pulping tank connected to the inlet of the filter press and the inlet of the conveying mechanism, and the discharge port of the filter press and the inlet of the pulping tank formed a discharge area, which is surrounded by a protective cover.

[0006] Preferably, the protective cover includes a light-resistant plate that seals the entire unloading area, and the light-resistant plate is supported by a support frame.

[0007] Preferably, the support frame includes a transverse support frame and a longitudinal support frame.

[0008] Preferably, the range of the transverse support frame is such that the light-resistant plate can surround the conveying mechanism and the pulping tank inlet.

[0009] Preferably, the longitudinal support frame is positioned such that the light-resistant plate can surround the feed inlet and conveying mechanism of the filter press.

[0010] Preferably, the lightfast sheet is transparent and lightfast, so that operators can observe the equipment status in real time.

[0011] Preferably, both the support frame and the light-resistant plate are made of corrosion-resistant materials to cope with corrosive substances in the working environment.

[0012] Preferably, the transmission mechanism is a belt.

[0013] Beneficial effects: Compared with the prior art, this utility model has the following significant advantages: (1) It protects the entire process from the filter press discharge port to the pulping tank, isolates the semi-finished material from the environment, effectively reduces the risk of introducing foreign objects during material transportation, and improves the quality of ferric phosphate; (2) It effectively prevents material splashing caused by the impact force generated when the material falls from the filter press to the conveyor belt; (3) It isolates the filter press discharge port, the conveyor belt and the operating area, effectively reducing the risk of mechanical injury to the operators; (4) It reduces the difficulty of manual cleaning and saves labor costs.

[0015] Figure 2 This is a perspective view of the protective device described in this utility model. Detailed Implementation

[0016] The technical solution of this utility model will be further described below with reference to the embodiments.

[0017] As shown in the figure, the protective device for preparing ferric phosphate according to this utility model includes a filter press 1, a conveying mechanism 2 located below the filter press 1 for conveying materials, and a pulping tank 3 connected to the conveying mechanism 2 by the feed inlet. The entire range from the discharge port of the filter press 1 to the feed inlet of the conveying mechanism 2 to the pulping tank 3 constitutes the discharge area, which is surrounded by a protective cover.

[0018] The protective cover includes a light-resistant plate 6 that seals the entire unloading area, and the light-resistant plate 6 is supported by a support frame.

[0019] The support frame includes a transverse support frame 4 and a longitudinal support frame 5.

[0020] The range of the transverse support frame 4 is such that the light-resistant plate 6 can surround the transmission mechanism 2 and the feed inlet of the pulping tank.

[0021] The range of the longitudinal support frame 5 is determined by the requirement that the light-resistant plate 6 can surround the feed port of the filter press 1 and the transmission mechanism 2.

[0022] Lightfastness plate 6 is transparent and lightfast, allowing operators to observe the equipment status in real time.

[0023] Both the support frame and the light-resistant plate 6 are made of corrosion-resistant materials to cope with corrosive substances in the working environment.

[0024] The transmission mechanism 2 is a belt.

[0025] The working principle of the protective device for ferric phosphate preparation described in this utility model is as follows: After being filtered by a filter press, the material falls onto a conveyor belt through the discharge port under its own gravity. The conveyor belt transports the material to the discharge end, and the material is then transferred to the pulping tank by a scraper between the discharge end of the conveyor belt and the inlet of the pulping tank. Throughout the entire material transport process, the equipment is surrounded by a protective cover, providing effective protection.

[0026] The protective cover isolates the semi-finished materials from the environment, effectively reducing the risk of introducing foreign objects during material transportation and improving the quality of the finished iron phosphate product.
