Description

Technical Field

[0001] The utility model relates to the technical field of a sand mill feed port, in particular to a sand mill feed valve port and a sand mill grinding chamber. Background Art

[0002] Sand mill, also known as bead mill, is mainly used for wet grinding of chemical liquid products. According to its performance, it can be roughly divided into horizontal sand mill, basket sand mill, vertical sand mill, etc.

[0003] It is mainly composed of machine body, grinding cylinder, sand grinding disc (push rod), grinding media, motor and feeding pump. The feeding speed is controlled by the feeding pump. The grinding media of this equipment is generally divided into zirconia beads, glass beads, zirconium silicate beads, etc.

[0004] In the process of feeding materials into the existing sand mill, due to the large particle size of the materials themselves or the agglomeration of the materials when they are placed, blockage or top bursting may occur during feeding.

[0005] When grinding materials, the fineness of grinding can be controlled by manually manipulating the grinding power, but if a blockage occurs during material feeding, the machine has to be shut down for maintenance to ensure safe use, which delays work efficiency and reduces economic benefits. Utility Model Content

[0006] In order to solve the above technical problems, the purpose of the utility model is to provide a sand mill feed valve port that avoids blockage during material feeding.

[0007] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows: a sand mill feed valve port, including a feed port, an elastic telescopic part, an assembly part, and a feed pipe. The feed port is fixedly assembled on the grinding chamber, the elastic telescopic part is arranged on the inner wall of the feed port, the feed pipe is assembled on the elastic telescopic part, and the assembly part is arranged inside the feed port for pre-dispersing the material.

[0008] The beneficial effect of the utility model is that by arranging elastic telescopic parts and a feed pipe on the feed port, when the device grinds the material, the vibration generated by the device itself is transmitted to the elastic telescopic parts, causing the elastic telescopic parts to vibrate and then drive the feed pipe to vibrate continuously, the material can be stirred in advance by relying on the vibration, and in conjunction with the assembly parts, the relative displacement between the two is utilized to achieve the dispersion of the material, thereby avoiding the blockage of the material when entering the feed port.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the elastic telescopic part includes a fixed ring, a telescopic ring and an elastic part. The inner wall of the fixed ring is provided with a movable groove along its circumferential direction. The telescopic ring is slidably assembled on the movable groove along the up and down directions. The elastic part is arranged on the movable groove and is located between the lower end of the telescopic ring and the fixed ring. The feed pipe is concentrically assembled on the telescopic ring.

[0011] The above technical solution is achieved by setting a fixed ring, a telescopic ring and an elastic member. When the device is in operation, the vibration of the device itself is transmitted to the elastic member, and the elastic member is used to drive the telescopic ring to vibrate up and down. The vibration of the device itself when working is utilized to achieve pre-dispersion of the material, while saving energy consumption.

[0012] Furthermore, the elastic member is a columnar spring, the upper end of the elastic member is connected and fixed to the lower end of the telescopic ring, and the lower end of the elastic member is connected and fixed to the lower end of the fixing ring.

[0013] The above technical solution uses an elastic member configured as a columnar spring and utilizes the elasticity of the elastic member itself to drive the telescopic ring to move on the fixed ring, so that the telescopic ring can telescope and vibrate using the vibration of the device itself.

[0014] Furthermore, the lower end of the assembly part is fixedly assembled in the feed port, and the upper end thereof extends into the feed pipe.

[0015] In the above technical solution, when the feed pipe vibrates up and down, the assembly parts can break up the materials entering the feed pipe, so that the agglomerated materials will not block the feed port, thus avoiding the occurrence of top bulging.

[0016] Furthermore, the assembly includes a fixing rod and a breaking rod, the fixing rod is horizontally fixedly assembled inside the feed port, the lower end of the breaking rod is vertically assembled on the fixing rod, the breaking rod is coaxially arranged with the feed pipe, and its upper end extends into the feed pipe.

[0017] The above technical solution provides a vertically arranged breaking rod, which can provide obstacles to the passing materials, thereby breaking up the agglomerated materials.

[0018] Furthermore, the breaking rod is provided with a plurality of strip-shaped protrusions spaced apart along its circumferential direction.

[0019] The above technical solution provides a plurality of strip-shaped protrusions on the breaking rod, so that the breaking rod can break the materials more thoroughly.

[0020] The second purpose of the utility model is to provide a sand mill grinding chamber which can avoid being blocked by materials.

[0021] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows: a sand mill grinding chamber includes a sand mill feed valve port.

[0022] Furthermore, it also includes a grinding chamber body, and the feed port is fixedly assembled on the grinding chamber body and communicated with the grinding chamber body.

[0023] The above technical solution assembles the sand mill feed valve port capable of automatic vibration on the grinding chamber body, so that the material can be pre-broken before entering the grinding chamber, avoiding the situation where the device is blocked and topped out when grinding the material.

[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] Example

[0032] like Figure 1-4 As shown, a sand mill feed valve port includes a feed port 3, an elastic telescopic part 4, an assembly part, and a feed pipe 1. The feed port 3 is fixedly assembled on the grinding chamber, the elastic telescopic part 4 is arranged on the inner wall of the feed port 3, the feed pipe 1 is assembled on the elastic telescopic part 4, and the assembly part is arranged inside the feed port 3 for pre-dispersing the material.

[0033] The working principle is: when the device is turned on to grind the material, the vibration is transmitted to the elastic telescopic part 4, and drives the feed pipe 1 to move up and down and vibrate. As the feed pipe 1 vibrates, the material enters the feed pipe 1 and will be pre-impacted with the vibration. At the same time, when the material passes through the assembly, the impact force can further break up the material, thereby reducing the possibility of material blockage.

[0034] The above technical solution can be achieved by arranging an elastic telescopic part 4 and a feed pipe 1 on the feed port 3. When the device grinds the material, the vibration generated by the device itself is transmitted to the elastic telescopic part 4, causing the elastic telescopic part 4 to vibrate and then drive the feed pipe 1 to vibrate continuously. The material can be pre-stirred by relying on the vibration, and the relative displacement between the two can be utilized in conjunction with the assembly parts to achieve the dispersion of the material, thereby avoiding blockage of the material when entering the feed port 3.

[0035] Preferably, the elastic telescopic member 4 includes a fixed ring 42, a telescopic ring 41 and an elastic member 44. The inner wall of the fixed ring 42 is provided with a movable groove 43 along its circumferential direction. The telescopic ring 41 is slidably assembled on the movable groove 43 along the up and down directions. The elastic member 44 is arranged on the movable groove 43 and is located between the lower end of the telescopic ring 41 and the fixed ring 42. The feed pipe 1 is concentrically assembled on the telescopic ring 41.

[0036] The working principle is as follows: when the sand mill grinds the material, the vibration generated by itself during grinding is transmitted to the elastic member 44, and the elastic member 44 is used to drive the telescopic ring 41 to vibrate up and down. At this time, the agglomerated material is broken up by the vibration and the mutual force between the materials, and the assembly parts are used to impact the material, thereby further improving the degree of breaking up of the material.

[0037] The above technical solution is provided with a fixed ring 42, a telescopic ring 41 and an elastic member 44. When the device is in operation, the vibration of the device itself is transmitted to the elastic member 44, and the elastic member 44 is used to drive the telescopic ring 41 to vibrate up and down. The vibration of the device itself when working is utilized to achieve pre-dispersion of the material, while saving energy consumption.

[0038] Preferably, the elastic member 44 is a columnar spring, the upper end of the elastic member 44 is connected and fixed to the lower end of the telescopic ring 41 , and the lower end of the elastic member 44 is connected and fixed to the lower end of the fixing ring 42 .

[0039] The above technical solution uses the elastic member 44 which is a columnar spring and utilizes the elasticity of the elastic member 44 to drive the telescopic ring 41 to move on the fixed ring 42, so that the telescopic ring 41 can telescope and vibrate by utilizing the vibration of the device itself.

[0040] Preferably, the lower end of the assembly part is fixedly assembled in the feed port 3 , and the upper end thereof extends into the feed pipe 1 .

[0041] In the above technical solution, when the feed pipe 1 vibrates up and down, the assembly parts can break up the materials entering the feed pipe 1, so that the agglomerated materials will not block the feed port 3, thus avoiding the occurrence of top bulging.

[0042] Preferably, the assembly includes a fixing rod 5 and a breaking rod 6, the fixing rod 5 is horizontally fixedly assembled inside the feed port 3, the lower end of the breaking rod 6 is vertically assembled on the fixing rod 5, the breaking rod 6 is coaxially arranged with the feed pipe 1, and its upper end extends into the feed pipe 1.

[0043] The working principle is as follows: when the material passes through the breaking rod 6, the agglomerated material can be broken up due to the impact, thereby avoiding the device from being blocked during feeding.

[0044] The above technical solution provides a vertically arranged breaking rod 6, which can provide obstacles to the passing materials and thus break up the agglomerated materials.

[0045] Preferably, the breaking rod 6 is provided with a plurality of strip-shaped protrusions 61 spaced apart along its circumferential direction.

[0046] The working principle is as follows: when the material passes through the breaking rod 6, the strip-shaped protrusion 61 increases the contact area with the material, thereby further improving the possibility of breaking up the material.

[0047] The above technical solution provides a plurality of strip-shaped protrusions 61 on the breaking rod 6, so that the breaking rod 6 can break the materials more thoroughly.

[0048] The second purpose of the utility model is to provide a sand mill grinding chamber which can avoid being blocked by materials.

[0051] The above technical solution assembles a sand mill feed valve port capable of automatic vibration on the grinding chamber body (2), so that the material can be pre-broken before entering the grinding chamber, thereby avoiding the situation where the device is blocked and topped out when grinding the material.
