Description

Technical Field

[0001] This application relates to the field of crushing mill technology, and in particular to a discharge port docking device for a crushing mill. Background Technology

[0002] A pulverizer is an experimental device used for sample pretreatment. This device rapidly and uniformly pulverizes samples to achieve the particle size and uniformity required for testing, thereby ensuring the accuracy and stability of the test results. It is widely applicable to laboratory sample processing of various grains, feeds and other agricultural by-products. Due to its high pulverization efficiency and simple operation, it has become a commonly used pretreatment device in the testing process.

[0003] However, in existing pulverizer structures, there is usually a discharge port below the grinding chamber, and a fixed platform is generally designed below the discharge port to place the receiving cylinder (or sample cup) to receive the pulverized material discharged from the grinding chamber. Although this docking method can complete the basic sample collection function, its sealing is poor, and the material is prone to overflow or scattering during the falling process, which not only causes sample loss, but also affects the accuracy of the test data, and increases the workload of equipment cleaning. Utility Model Content

[0004] In order to solve the problems of poor sealing and easy spillage or dispersion of samples in the existing crushing and grinding equipment mentioned in the background art, this application provides a discharge port docking device for crushing and grinding mills.

[0005] The present application provides a discharge port docking device for a pulverizing mill, which adopts the following technical solution: A discharge port docking device for a pulverizing mill, comprising: The cover plate has a vertically penetrating material feeding channel on its surface, which is connected to the discharge port of the crushing and grinding mill shell; the cover plate includes a cover body that matches the upper end of the receiving cylinder. An elastic support device is provided below the cover body and forms an installation gap with the cover body. The elastic support device includes an open portion with one end open and a support portion protruding towards the cover body. The open portion is used to allow the receiving cylinder to enter the elastic support device in the horizontal direction, and the support portion is used to provide an upward elastic support force to the receiving cylinder in the vertical direction so that the upper end of the receiving cylinder can be reliably attached to the cover body.

[0006] By adopting the above technical solution, a cover plate with an internal channel is set below the discharge port of the pulverizer casing, allowing the sample to pass directly through the cover plate. The receiving cylinder is installed and fixed using an elastic support device, and the upper end of the receiving cylinder is reliably fitted with the cover plate. This can shorten the drop difference between the receiving cylinder and the discharge port of the pulverizer casing, and enable rapid sample collection under small drop conditions through the reliable fit between the receiving cylinder and the cover plate. This is beneficial to improving the sealing performance between the receiving cylinder and the cover plate and preventing the sample from scattering during the fall.

[0007] Optionally, the cover plate further includes a boss that is fixedly connected to the cover body and extends upward and outward. The upper surface of the boss is an arc surface, and the material discharge channel passes through the boss and the cover body in sequence.

[0008] By adopting the above technical solution and setting a boss structure with an arc surface on the upper surface, it can be tightly fitted with the outer wall of the circular housing, thereby preventing the sample from flying outward from the connection between the housing and the cover plate. This not only helps to improve the sealing performance at the connection between the two, but also improves the connection stability of the cover plate under the housing.

[0009] Optionally, the outer side of the boss is connected to a downwardly extending mounting part, the lower plane of the mounting part is lower than the lower plane of the cover body, and the elastic support device is connected to the lower surface of the mounting part.

[0010] By adopting the above technical solution, the elastic support device is installed below the cover plate to achieve a fixed connection, and the lower plane of the installation part is lower than the lower plane of the cover body, so as to form an installation gap between the elastic support device and the cover body, which facilitates the assembly of the receiving cylinder.

[0011] Optionally, a sealing ring is installed below the cover body, and when the receiving cylinder enters the elastic support device, the upper end of the receiving cylinder abuts against the sealing ring.

[0012] By adopting the above technical solution, the sealing performance of the receiving cylinder after assembly can be further improved by using a sealing ring, thus greatly enhancing the sealing effect.

[0013] Optionally, the elastic support device includes two symmetrically arranged elastic plates, each elastic plate having an outwardly protruding arc-shaped portion in the middle, and a limiting area for positioning the upper end of the docking cylinder is formed between the two arc-shaped portions.

[0014] By adopting the above technical solution, the two elastic plates have a certain elastic deformation, which makes it easy for the receiving cylinder to enter the limiting area through the open part, and the limiting area is used to radially position the receiving cylinder, preventing the receiving cylinder from moving in the horizontal direction, which helps to improve the installation stability of the receiving cylinder during the receiving process.

[0015] Optionally, one end of the elastic sheet is a fixed end, which is fixedly connected to the cover plate, and the other end of the elastic sheet is a movable end, which extends outward at an angle, and the opening is located in the area between the two movable ends.

[0016] By adopting the above technical solution and setting an inclined outward-extending movable end, the receiving cylinder can be quickly inserted between the two elastic plates, improving the convenience of the receiving cylinder installation.

[0017] Optionally, the support portion is disposed on the arc-shaped portion and in the direction close to the open portion.

[0018] By adopting the above technical solution, during the process of using the support part to support the receiving cylinder, the receiving cylinder can always be made to move away from the open part, which can prevent the receiving cylinder from easily detaching from the two elastic plates, improve the stability of the installation, and the support part can be used to push the receiving cylinder upward, so that the receiving cylinder and the sealing ring are tightly fitted, improving the sealing performance.

[0019] Optionally, the fixed ends of the two elastic sheets are connected to each other.

[0020] By adopting the above technical solution, unlike the above two elastic sheets which are separate structures, the two elastic sheets are connected as a whole, which can also meet the positioning and support effect of the docking cylinder. At the same time, it can also facilitate the rapid assembly of the elastic support device.

[0021] Optionally, the upper edge of the receiving cylinder extends outward to form a flange, which can be placed within the installation gap, and the lower surface of the flange contacts the arc-shaped part and the upper surface contacts the sealing ring.

[0022] By adopting the above technical solution, the flange can be positioned within the installation gap, achieving vertical positioning, and has the advantage of simple assembly process.

[0023] Optionally, a fixing plate is also included, wherein the cover plate and the elastic sheet are respectively fixed to the fixing plate.

[0024] By adopting the above technical solution, different installation methods can be used to install and fix the cover plate and elastic sheet according to actual needs, which has a wide range of applications.

[0025] In summary, this application includes at least one of the following beneficial technical effects: This invention features a cover plate with an internal channel connected below the discharge port of the pulverizer casing, allowing the sample to pass directly through the cover plate. An elastic support device is used to install and fix the receiving cylinder, ensuring a reliable fit between the upper end of the receiving cylinder and the cover plate. This reduces the drop difference between the receiving cylinder and the discharge port of the pulverizer casing, and enables rapid sample collection even with a small drop due to the reliable fit between the receiving cylinder and the cover plate. It also improves the sealing performance between the receiving cylinder and the cover plate, preventing the sample from scattering during its descent. Attached Figure Description

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] This application discloses a discharge port docking device for a pulverizing mill, comprising: The cover plate 1 has a vertically penetrating material discharge channel 102 on its surface, which is connected to the discharge port 601 of the crushing mill shell 6; the cover plate 1 includes a cover body 101 that matches the upper end of the receiving cylinder 4. In this example, the cover body 101 has a circular shape, and the upper end of the receiving cylinder 4 also has a circular shape and matches the cover body 101. An elastic support device is provided below the cover body 101 and forms an installation gap 7 between it and the cover body 101. The elastic support device includes an open portion 305 with one end open and a support portion 306 protruding towards the cover body 101. The open portion 305 allows the receiving cylinder 4 to enter the elastic support device in a horizontal direction, and the support portion 306 provides an upward elastic support force to the receiving cylinder 4 in a vertical direction, so that the upper end of the receiving cylinder 4 can reliably fit with the cover body 101. In specific use, the receiving cylinder 4 enters the middle area of ​​the elastic support device from the open portion 305 and is located below the cover body 101. The support portion 306 can provide an upward force to the receiving cylinder 4 to achieve a fitting effect with the cover body 101.

[0030] In this example, the cover plate 1 also includes a boss 103 that is fixedly connected to the cover body 101 and extends upward and outward. The upper surface of the boss 103 is arc-shaped, and the feeding channel 102 passes through the boss 103 and the cover body 101 in sequence. The housing 6 of the pulverizer is an upright circular structure, and its discharge port 601 is located at the lower end of the outer wall of the housing 6. Since the housing 6 is circular, to achieve a tight fit between the cover plate 1 and the housing 6, the surface of the boss 103 is designed to be an arc-shaped structure with the same curvature as the outer wall of the housing 6, allowing for better fit. After the two are in contact, the feeding channel 102 communicates with the discharge port 601, enabling feeding. More specifically, the cover plate 1 has mounting holes, and the cover plate 1 is bolted to the bottom of the housing 6, achieving a fixed connection with the housing 6. In actual use, the cover plate 1 is always in a fixed state, ensuring effective communication between the feeding channel 102 and the discharge port 601.

[0031] In this example, the outer side of the boss 103 is connected to a downwardly extending mounting part 104. The lower plane of the mounting part 104 is lower than the lower plane of the cover body 101. The elastic support device is connected to the lower surface of the mounting part 104. The boss 103 and the cover body 101 are integrally formed, and the mounting part 104 and the boss 103 are integrally formed. The lower plane of the mounting part 104 extends to the lower position of the cover body 101. It is mainly used to form an installation gap 7 between the elastic support device and the cover body 101 after the elastic support device is installed, so that the flange of the upper edge of the receiving cylinder 4 can enter into the installation gap 7.

[0032] Specifically, a sealing ring 2 is installed below the cover body 101. When the receiving cylinder 4 enters the elastic support device, the upper end of the receiving cylinder 4 abuts against the sealing ring 2. The sealing ring 2 is fixed at the bottom of the cover body 101 and is mainly used to fit with the upper end of the receiving cylinder 4 to further improve the sealing performance.

[0033] Specifically, the elastic support device includes two symmetrically arranged elastic plates 3, which can be made of spring steel and have a certain deformation capacity. The elastic plate 3 has an outwardly protruding arc-shaped part 301 in the middle. A limiting area 304 for positioning the upper end of the receiving cylinder 4 is formed between the two arc-shaped parts 301. The limiting area 304 is a circular area. After the receiving cylinder 4 is placed in this area, it can be radially positioned, which is beneficial to the installation stability of the receiving cylinder 4.

[0034] Specifically, one end of the elastic sheet 3 is a fixed end 302, which is fixedly connected to the cover plate 1 by means of bolts. The other end of the elastic sheet 3 is a movable end 303, which extends outward at an angle. The opening 305 is located in the area between the two movable ends 303, which allows the receiving cylinder 4 to quickly enter the opening 305 and squeeze and deform the two elastic sheets 3 before entering the limiting area 304.

[0035] Specifically, the support portion 306 is disposed on the arc-shaped portion 301 and in the direction close to the open portion 305.

[0036] It is understood that in other embodiments, the fixed ends 302 of the two elastic sheets 3 are connected to each other, that is, the entire elastic support device is an integral structure, which can also achieve the positioning and support effect of the docking cylinder 4.

[0037] Specifically, the upper edge of the receiving cylinder 4 extends outward to form a flange, which can be placed within the installation gap 7, and the lower surface of the flange contacts the arc-shaped part 301 and the upper surface contacts the sealing ring 2.

[0038] Understandably, in addition to installing the cover plate 1 under the housing 6 and the elastic sheet 3 under the cover plate 1, other embodiments also include a fixing plate 5, on which the cover plate 1 and the elastic sheet 3 are respectively fixed. In practice, the fixing plate 5 is mainly used to install the housing 6 of the crushing mill.

[0039] In this example, the inside of the mill housing 6 is the grinding chamber, which is used to crush and grind materials. The end of the mill is also hinged with a door panel, which will not be described in detail here.

[0040] When this discharge port docking device for a pulverizer is in use, the material is first pulverized and ground inside the casing 6 of the pulverizer. After the sample is ground, it enters the discharge channel 102 on the cover plate 1 through the discharge port 601 at the lower end of the casing 6, and finally falls into the receiving cylinder 4 for collection.

[0041] When installing the receiving cylinder 4, the operator inserts it horizontally between the two elastic plates 3 through the opening 305, and pushes the flange at the top of the receiving cylinder 4 into the installation gap 7 formed between the cover body 101 and the elastic plates 3. During this process, the limiting area 304 formed by the arc-shaped part 301 of the elastic plate 3 provides radial positioning for the receiving cylinder 4, and the support part 306 generates an upward supporting force on the flange, so that the upper end of the receiving cylinder 4 is tightly fitted with the sealing ring 2 at the bottom of the cover body 101. Through the fitting effect of the sealing ring 2, the spillage or scattering of materials during the falling process is effectively prevented, ensuring the sealing and stability of the collection process.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
