Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbonate production, in particular to a grinding device for calcium carbonate production. Background Art

[0002] Calcium carbonate is an inorganic compound and a major component of limestone, marble, and other materials. It is essentially insoluble in water but soluble in hydrochloric acid. Calcium carbonate is found in rocks such as aragonite, calcite, chalk, limestone, marble, and travertine, and is also a major component of the bones or shells of some animals. Calcium carbonate is also an important building material with a wide range of industrial applications. During its production, calcium carbonate requires a grinding device. China has authorized a utility model patent (Announcement No.: CN221182990U) that discloses a grinding device for producing calcium carbonate powder. This device uses a telescopic and rotating slider that slides into a chute. A cover plate covers the feed tube, effectively preventing debris from splashing. The grinding block rotates in contact with the curved grinding plate, ensuring that the calcium carbonate debris is ground only after being discharged, thus eliminating the problem of unground debris falling through gaps.

[0003] However, the above device still has some shortcomings when used: specifically, in the prior art, a filter screen is arranged in a "mouth"-shaped frame, and a notch is provided on one side of the frame. The calcium carbonate falling on the filter screen is vibrated and discharged by the operation of a vibration motor, and the filtered large particles are vibrated and discharged through the notch. In this process, the discharge of large particles depends entirely on the inertial force generated by the vibration, and there is a lack of a targeted discharge mechanism, resulting in a slow and incomplete discharge process, which affects the overall working efficiency of the grinding device. Therefore, in response to the above situation, a grinding device for calcium carbonate production is proposed. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 The utility model provides a technical solution: a grinding device for calcium carbonate production, comprising a grinding box 1 and a scraper 8, the grinding box 1 having a crushing chamber and a collecting chamber 101, and the crushing chamber and the collecting chamber 101 are connected to each other.

[0024] The top of the grinding box 1 has a feed port 105 , which is connected to the grinding chamber. The bottom of the grinding box 1 has a discharge port 102 and a discharge port 103 , which are both connected to the collecting chamber 101 .

[0025] A U-shaped frame 2 is provided in the collecting chamber 101, and a filter screen 3 is provided on the inner wall of the U-shaped frame 2. A first chute 201 is provided on both sides of the inner wall of the U-shaped frame 2. A slider 4 is slidably fitted in the first chute 201. A baffle 5 is fixedly connected to the two sliders 4.

A spring 6 is provided on one side of the inner wall of the two first chute 201, and one end of the spring 6 is fixedly connected to the slider 4.

[0026] Among them, a third spring can be set on the outer wall of the U-shaped frame 2, and the bottom of the third spring is fixed to the bottom surface of the inner wall of the collecting chamber 101. By setting the third spring, the vibration amplitude of the U-shaped frame 2 is increased and the screening effect is improved.

[0027] An assembly port is provided on one side of the outer wall of the grinding box 1 , which is communicated with the collecting chamber 101 . A cylinder 7 is provided on the assembly port, which penetrates into the collecting chamber 101 .

[0028] The bottom of the scraper 8 is a conical structure. The bottom of the scraper 8 contacts the filter 3. A top rod 9 is provided on one side of the scraper 8. There are two top rods 9. A second slide groove 801 is provided on the side of the scraper 8 away from the top rod 9. There are two second slide grooves 801. The two second slide grooves 801 are slidably fitted with a connecting rod 10, and the moving end of the cylinder 7 is connected to the connecting rod 10.

[0029] In this embodiment, a vibration motor is provided on the collection chamber 101 , a vibration end of the vibration motor is connected to one side of the outer wall of the U-shaped frame 2 , and the vibration motor is externally connected to a power supply and a switch.

[0030] When in use, the electrical equipment in the device is connected to an external power supply and switch. After the material is crushed and ground from the crushing chamber, it falls on the filter screen 3. The switch of the vibration motor is turned on. The vibration motor works to vibrate the U-shaped frame 2 and then the filter screen 3, and the calcium carbonate powder on the filter screen 3 is vibrated and screened. The calcium carbonate powder after vibration screening is discharged from the discharge port 102 and falls into the collection box at the bottom of the grinding box 1. When the large particles of material remaining on the filter screen 3 need to be cleaned, the switch of the cylinder 7 is turned on to make it work. The cylinder 7 works to push the scraper 8 to move. The movement of the scraper 8 can scrape the large particles on the filter screen 3 and move it toward one side of the baffle 5. During the movement of the scraper 8, the push rod 9 also moves accordingly. After the push rod 9 first hits the baffle 5, as the push rod 9 continues to move, the push rod 9 hits the baffle 5 and causes the baffle 5 to move, that is, the slider 4 slides in the first chute 201 and squeezes the spring 6, so that the scraper 8 can scrape the large particles on the filter screen 3 out and drop them into the discharge port 103 and be discharged through the guide plate 104.

[0032] In this embodiment, the inclined guide plate 104 can guide the discharged large particles.

[0033] In this embodiment, Figure 1 and Figure 2 As shown, a crushing and grinding mechanism is provided in the crushing chamber.

[0034] In this embodiment, the composition structure of the crushing and grinding mechanism is the same as the relevant composition structure used for crushing and grinding calcium carbonate in the prior art (Announcement No.: CN221182990U), and will not be described in detail here.

[0035] In this embodiment, Figure 2 、 Figure 4 and Figure 5 As shown, the connecting rod 10 is U-shaped, and both ends of the connecting rod 10 have blocks that match the collecting cavity 101.

[0036] In this embodiment, by setting the block to slide with the second slide groove 801, when the vibration screening operation is carried out, the vibration generated by the vibration motor enables the scraper 8 and the connecting rod 10 to achieve local up and down movement, thereby ensuring that the filter screen 3 is subjected to up and down vibrations, causing the scraper 8 to vibrate, thereby reducing the impact on the cylinder 7 and affecting the service life of the cylinder 7.

[0037] In this embodiment, Figure 1 、 Figure 2 and Figure 5 As shown, the bottom of the U-shaped frame 2 has a conical guide hopper, which is connected to the discharge port 102.
