[0002] In the production of cellulose products, the product needs to be screened by a corresponding metal sieve after drying and before crushing to ensure that the crusher is not damaged. At the same time, stable material supply is needed to ensure the stable operation of the crusher. The patent file with the patent number CN216936427U discloses a refined cotton crusher for high-melting hydroxypropyl methyl cellulose production. After the refined cotton is crushed by the crusher body, the crusher body sends the crushed refined cotton into the impurity removal device through the discharge port. The conveying mechanism sends the crushed refined cotton to the next process. In the process of feeding the conveying mechanism, the impurity removal mechanism can reduce the heavy metal impurities and silt impurities in the material, thereby ensuring the quality of the cellulose. However, in the above technical solution, only weight screening is used for impurity removal, which may not remove some small-sized metal impurities, still affecting the safety and stable operation of the crusher.

[0016] The present application will be further described below in combination with the drawings.

[0017] According to Figure 1 The present application embodiment proposes a cellulose feeding and crushing equipment, which comprises a crusher 1, characterized in that a metal detection device, a feeding device and a storage device are sequentially arranged on the side of the feeding port of the crusher 1.

[0018] The metal detection device comprises a feeding pipe 5 communicated with the feeding device, and a metal detector 2 is arranged at the end of the feeding pipe 5 away from the vibration feeding device.

[0019] First of all, it needs to be pointed out that the raw material enters the feeding device from the storage device, and the detected and removed metal impurities are discharged from the second discharge port 7 under the detection of the metal detector 2.

[0020] Specifically, the above-mentioned pulverizer 1 is a conventional pulverizer 1 device, and the metal detector 2 is a conventional metal detector, which is usually composed of a metal detector and an automatic rejection assembly. The metal detector is internally distributed with three sets of coils, namely a central transmitting coil and two symmetrical receiving coils. A high-frequency variable magnetic field is generated by the oscillator connected to the transmitting coil in the middle. In the idle state, the induced voltages of the two receiving coils cancel each other out and reach a balanced state before the magnetic field is disturbed. When metal impurities enter the magnetic field area, the magnetic field is disturbed, and this balance is broken. The induced voltages of the two receiving coils cannot be canceled out, and the uncanceled induced voltages are amplified and processed by the control system and generate an alarm signal (metal impurities are detected). The metal detector can drive the automatic rejection device using the alarm signal. In the present embodiment, the raw materials enter the above-mentioned metal detector through the above-mentioned feeding pipe. After detecting metal impurities, the automatic rejection assembly is a conventional automatic screening mechanism adapted to the metal detector. The automatic rejection assembly transports the metal impurities to the second discharge port 7, and the raw materials after the rejection work enter the pulverizer 1 from the first discharge port 6.

[0021] Specifically, the above-mentioned feeding device includes a spiral vibrating elevator 3. The lower end of the vibrating elevator is connected to the above-mentioned discharge device, and the upper end of the vibrating elevator is connected to the above-mentioned feeding pipe 5. The spiral vibrating elevator 3 specifically includes a vibrating mechanism and a spiral conveying mechanism. The raw materials rotate on the spiral conveying mechanism and spiral upward to be gradually conveyed upward. At the same time, the raw materials are evenly laid on the spiral conveying mechanism under the vibration of the vibrating mechanism, ensuring the uniformity and stability of the raw material conveying.

[0022] Moreover, the above-mentioned spiral vibrating elevator 3 is provided with an inner spiral plate. The inner spiral plate is internally provided with a water flow channel for introducing hot water. The raw materials are laid on the upper surface of the inner spiral plate, and the inner spiral plate gradually moves upward to realize the conveying of the raw materials. Hot water is introduced into the water flow channel to further dry the raw materials to recover the gas.

[0023] The above-mentioned storage device includes a buffer bin 4. The lower end of the buffer bin 4 is connected to the above-mentioned feeding device. The buffer bin 4 is internally provided with a pulse dust collector. The materials in the buffer bin 4 realize the dust removal effect through the pulse dust collector. Moreover, the upper end of the buffer bin 4 is connected to a fan 8. The fan 8 is used to recover the tail gas to realize the recovery of the raw material tail gas.

[0024] In actual work, the problem of continuous feeding without manual intervention due to the failure of the crusher 1 may occur, causing the entire device to be blocked, in order to solve the above problems, the position of the lower end of the buffer bin 4 connected with the feeding device is provided with an automatic partition, the automatic partition is electrically connected with the crusher 1, when the crusher 1 fails, the automatic partition moves to isolate the buffer bin 4 and the feeding device, the specific structure of the automatic partition is an electric telescopic rod connected with a transmission mechanism, the transmission end of the transmission mechanism is connected with a partition, realizing the effect of automatic blocking.

[0025] In summary, the cellulose feeding and crushing equipment is provided, which comprises a crusher 1, a metal detection device, a feeding device and a storage device are sequentially arranged on the feeding port side of the crusher 1; the metal detection device comprises a feeding pipeline 5 connected with the feeding device, a metal detector 2 is arranged at the end of the feeding pipeline 5 away from the vibrating feeding device, the metal detector 2 is provided with a first discharge port 6 and a second discharge port 7, and the first discharge port 6 is connected with the feeding port of the crusher 1; in the production of cellulose products, metal detection is required after drying and before crushing to ensure safety, and stable material supply is required to ensure the stable operation of the crusher 1; by adding the metal detector 2, the spiral vibrating elevator 3 and the buffer bin 4, the metal detection, uniform feeding and tail gas recovery of cellulose products are realized, and the safety and stability of the cellulose feeding and crushing process are ensured.
