Description

Technical Field

[0001] This utility model relates to the field of feed-grade dicalcium phosphate crushing technology, specifically a pre-crushing device for the production of feed-grade dicalcium phosphate. Background Technology

[0002] Feed-grade dicalcium phosphate is used in feed processing as a phosphorus and calcium supplement. A pre-crushing device for producing feed-grade dicalcium phosphate is a piece of equipment used to initially crush raw materials such as phosphate rock, so that subsequent processes such as grinding, flotation, and extraction can be carried out more efficiently. This device is usually the first step in the entire dicalcium phosphate production process, and its main purpose is to crush large pieces of phosphate rock into smaller particles to improve the efficiency of subsequent processes and product quality.

[0003] For example, the pre-crushing device for producing feed-grade dicalcium phosphate disclosed in Chinese Patent CN212493312U uses a scraper to scrape away residual material adhering to the conveyor belt, thus effectively cleaning the conveyor belt and preventing material from sticking to it. A first motor drives the crushing plate and shearing plate to rotate, crushing the material entering the crushing chamber. The crushed material is discharged from the outlet. Because a central hole is provided on the crushing plate, and the central shaft of the traditional crushing frame is eliminated, material adhesion and accumulation on the central shaft are prevented, and the material can pass through the central hole for transfer, avoiding excessive concentration between two adjacent crushing plates and greatly reducing blockage. The presence of inner and outer crushing teeth on the crushing plate and stepped grooves on the shearing plate achieves excellent crushing results.

[0004] While this structure can reduce material adhesion, some highly viscous materials still adhere to the outer wall of the crushing device during operation. Therefore, we propose a pre-crushing device for the production of feed-grade dicalcium phosphate that can promptly clean the material adhering to the outer wall of the crushing device to avoid prolonged adhesion and difficulty in cleaning, thereby improving the crushing effect. Utility Model Content

[0005] The purpose of this invention is to provide a pre-crushing device for the production of feed-grade dicalcium phosphate, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pre-crushing device for producing feed-grade dicalcium phosphate, comprising a crushing box, a support fixedly installed on the outer wall of the crushing box, a motor fixedly installed at the end of the support away from the crushing box, and a processing component disposed on the outside of the motor, the processing component including a vibration component disposed on the outside of the motor, and an auxiliary component disposed on the outside of the vibration component.

[0007] Preferably, the vibration assembly includes a rotating rod fixedly installed at the output end of the motor, a drive gear fixedly sleeved on the outer wall of the rotating rod, a rotating roller arranged on the side of the drive gear, a sliding groove opened on the outer wall of the rotating roller, a first magnetic plate fixedly installed on the inner wall of the sliding groove, a second magnetic plate slidably arranged inside the sliding groove, a breaking tooth fixedly installed on the side wall of the second magnetic plate, and a driven gear meshing on the outer wall of the drive gear.

[0008] Preferably, the auxiliary component includes a protrusion fixedly installed on the end of the rotating rod away from the motor, a fixing block fixedly installed on the outer wall of the crushing box, an air pipe fixedly sleeved inside the fixing block, a first magnetic ring fixedly installed on the inner wall of the air pipe, a second magnetic ring slidably arranged inside the air pipe, a sealing ring fixedly installed on the side wall of the second magnetic ring, a squeezing rod fixedly installed on the side of the sealing ring away from the second magnetic ring, and an air jet plate connected to the end of the air pipe away from the squeezing rod.

[0009] Preferably, the second magnetic plate and the first magnetic plate are magnetically repulsive, and the outer wall of the crushing tooth is slidably disposed inside the groove. Under the restriction of magnetic repulsion, the crushing tooth that is not squeezed can be reset and pushed to generate vibration, thereby cleaning the feed-grade dicalcium phosphate adhering to its outer wall.

[0010] Preferably, there are two rotating rollers symmetrically distributed around the center line of the crushing box. Under the constraint of the two opposing rotating rollers, feed-grade dicalcium phosphate can be pre-crushed.

[0011] Preferably, the sealing ring slides in a sealed manner with the inside of the air pipe, and the outer wall of the jet plate is fixedly installed with the inner wall of the crushing box. Under the restriction of the sealing ring and the air pipe, the sealing ring pushes the gas inside the air pipe and sprays it out through the jet plate to clean the material adhering to the outer wall of the roller.

[0012] Preferably, the second magnetic ring and the first magnetic ring are magnetically repulsive, the outer wall of the protrusion is arc-shaped, and the end of the extrusion rod away from the sealing ring is frustum-shaped. Under its constraint, the extrusion rod can be smoothly extruded with the protrusion. Under the constraint of magnetic repulsion, the extrusion rod that is not being extruded can be reset and pushed.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This pre-crushing device for producing feed-grade dicalcium phosphate comprises a vibrating assembly. When processing feed-grade dicalcium phosphate, pre-crushing is required. The dicalcium phosphate is fed into a crushing chamber. Upon starting the motor, a rotating rod fixedly mounted at its output end rotates, causing a rotating roller fixedly sleeved on the outer wall of the rod to rotate as well. The roller drives the internally sliding crushing teeth to rotate. Due to the meshing of the driving and driven gears, the rotating rod, under their constraint, drives the driving gear to rotate, simultaneously causing the driven gear to rotate. The two rotating rollers rotate in opposite directions, thus crushing the feed-grade dicalcium phosphate entering the crushing chamber. In the calcium crushing process, when the crushing teeth come into contact with and crush feed-grade dicalcium phosphate, they drive the second magnetic plate to slide into the chute. When the crushing teeth rotate and no longer crush the feed-grade dicalcium phosphate, the magnetic repulsion between the second and first magnetic plates pushes the second magnetic plate and the crushing teeth outward from the chute, causing them to vibrate and dislodging the feed-grade dicalcium phosphate material adhering to the outer wall of the crushing teeth. This structure can pre-crush feed-grade dicalcium phosphate and, under the constraint of magnetic repulsion, can push the second magnetic plate and the crushing teeth to prevent material from adhering to their outer wall and affecting the crushing effect.

[0015] 2. This pre-crushing device for producing feed-grade dicalcium phosphate consists of an auxiliary component. When the rotating roller and crushing teeth crush the feed-grade dicalcium phosphate, the crushing teeth vibrate to initially clean the feed-grade dicalcium phosphate adhering to its outer wall. When the rotating rod rotates, the protrusion fixedly installed at its end rotates accordingly. The outer wall of the protrusion slides and squeezes the end of the extrusion rod away from the sealing ring, causing the extrusion rod to drive the sealing ring and the second magnetic ring to slide into the air pipe. Since the sealing ring and the air pipe slide in a sealed manner, under its restriction, the sealing ring pushes the gas inside the air pipe, which is ejected through the air jet plate connected to the end of the air pipe, blowing off the feed-grade dicalcium phosphate adhering to the outer wall of the rotating roller. When the protrusion no longer squeezes the extrusion rod, under the restriction of the magnetic repulsion between the second magnetic ring and the first magnetic ring, the second magnetic ring is reset and pushed. This reciprocating motion can clean the outer wall of the rotating roller, preventing the material from adhering to the outer wall of the rotating roller for a long time. Attached Figure Description

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] Example 1: A preferred embodiment of the pre-crushing device for producing feed-grade dicalcium phosphate provided by this utility model is as follows: Figures 1 to 6 As shown: A pre-crushing device for the production of feed-grade dicalcium phosphate, including a crushing box 1;

[0025] A bracket 2 is fixedly installed on the outer wall of the crushing box 1;

[0026] A motor 3 is fixedly installed at the end of the support 2 away from the crushing box 1;

[0027] The processing assembly 4 is located outside the motor 3. The processing assembly 4 includes a vibration assembly 41 located outside the motor 3. The vibration assembly 41 includes a rotating rod 411 fixedly installed at the output end of the motor 3. A drive gear 412 is fixedly sleeved on the outer wall of the rotating rod 411. A rotating roller 413 is arranged on the side of the drive gear 412. A sliding groove 414 is opened on the outer wall of the rotating roller 413. A first magnetic plate 415 is fixedly installed on the inner wall of the sliding groove 414. A second magnetic plate 416 is slidably arranged inside the sliding groove 414. A breaking tooth 417 is fixedly installed on the side wall of the second magnetic plate 416. A driven gear 418 meshes with the outer wall of the drive gear 412.

[0028] In this embodiment, when processing feed-grade dicalcium phosphate, it needs to be pre-crushed. It is added into the crushing chamber 1, and the motor 3 is started. The rotating rod 411 fixedly installed at its output end rotates accordingly, and the rotating roller 413 fixedly sleeved on the outer wall of the rotating rod 411 rotates accordingly. The rotating roller 413 drives the internally sliding crushing teeth 417 to rotate. Because the driving gear 412 meshes with the driven gear 418, under its constraint, the rotating rod 411 drives the driving gear 412 to rotate, and simultaneously causes the driven gear 418 to rotate. The two rotating rollers 413 rotate in opposite directions, crushing the feed-grade dicalcium phosphate that has entered the crushing chamber 1. When the crushing teeth 417 and the feed... When the feed-grade dicalcium phosphate is crushed, it drives the second magnetic plate 416 to slide into the groove 414. When the crushing tooth 417 rotates and no longer crushes the feed-grade dicalcium phosphate, under the magnetic repulsion between the second magnetic plate 416 and the first magnetic plate 415, the second magnetic plate 416 and the crushing tooth 417 are pushed outward from the groove 414, causing the second magnetic plate 416 and the crushing tooth 417 to vibrate, shaking off the feed-grade dicalcium phosphate material attached to the outer wall of the crushing tooth 417. This structure can pre-crush the feed-grade dicalcium phosphate, and at the same time, under the magnetic repulsion, it can push the second magnetic plate 416 and the crushing tooth 417 to avoid the material adhering to their outer wall, which would affect the crushing effect.

[0029] Furthermore, the second magnetic plate 416 and the first magnetic plate 415 are magnetically repulsive, and the outer wall of the crushing tooth 417 is slidably disposed inside the groove 414. Under the restriction of magnetic repulsion, the crushing tooth 417, which is not squeezed, can be reset and pushed to generate vibration, thereby cleaning the feed-grade dicalcium phosphate adhering to its outer wall.

[0030] Furthermore, there are two rotating rollers 413, symmetrically distributed around the center line of the crushing box 1. Under the constraint of the two opposing rotating rollers 413, feed-grade dicalcium phosphate can be pre-crushed.

[0031] Example 2: Based on Example 1, a preferred embodiment of the pre-crushing device for producing feed-grade dicalcium phosphate provided by this utility model is as follows: Figures 1 to 6 As shown: The auxiliary component 42 includes a protrusion 421 fixedly installed on the end of the rotating rod 411 away from the motor 3. A fixing block 422 is fixedly installed on the outer wall of the crushing box 1. An air pipe 423 is fixedly sleeved inside the fixing block 422. A first magnetic ring 424 is fixedly installed on the inner wall of the air pipe 423. A second magnetic ring 425 is slidably arranged inside the air pipe 423. A sealing ring 426 is fixedly installed on the side wall of the second magnetic ring 425. A squeezing rod 427 is fixedly installed on the side of the sealing ring 426 away from the second magnetic ring 425. An air jet plate 428 is connected to the end of the air pipe 423 away from the squeezing rod 427.

[0032] In this embodiment, when the rotating roller 413 and the crushing teeth 417 crush feed-grade dicalcium phosphate, the crushing teeth 417 can initially clean the feed-grade dicalcium phosphate adhering to its outer wall through vibration. When the rotating rod 411 rotates, the protrusion 421 fixedly installed at its end rotates accordingly. The outer wall of the protrusion 421 slides and squeezes the end of the extrusion rod 427 away from the sealing ring 426, causing the extrusion rod 427 to drive the sealing ring 426 and the second magnetic ring 425 to slide into the air pipe 423. Due to the sealing ring 426 and the air pipe 425... 23 is a sealed sliding mechanism. Under its constraint, the sealing ring 426 pushes the gas inside the air pipe 423, which is then ejected through the jet plate 428 connected to the end of the air pipe 423, blowing off the feed-grade dicalcium phosphate adhering to the outer wall of the roller 413. When the protrusion 421 is no longer pressed against the extrusion rod 427, the second magnetic ring 425 is reset and pushed by the magnetic repulsion between the second magnetic ring 425 and the first magnetic ring 424. This reciprocating motion can clean the outer wall of the roller 413, preventing materials from adhering to the outer wall of the roller 413 for a long time.

[0033] Furthermore, the sealing ring 426 slides and seals inside the air pipe 423, and the outer wall of the jet plate 428 is fixedly installed on the inner wall of the crushing box 1. Under the restriction of the sealing ring 426 and the air pipe 423, the sealing ring 426 pushes the gas inside the air pipe 423, which is then sprayed out through the jet plate 428 to clean the material adhering to the outer wall of the rotating roller 413.

[0034] In addition, the second magnetic ring 425 and the first magnetic ring 424 are magnetically repulsive, the outer wall of the protrusion 421 is arc-shaped, and the end of the extrusion rod 427 away from the sealing ring 426 is frustoconical. Under its constraint, the extrusion rod 427 and the protrusion 421 can be smoothly extruded. Under the constraint of magnetic repulsion, the extrusion rod 427 that is not extruded can be reset and pushed.

Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
