Description

Technical Field

[0001] The invention relates to slurry sand mill production and processing equipment, in particular to a uniform speed constant flow pump with a vortex cam. Background Art

[0002] Sand mill, also known as bead mill, is mainly used for wet grinding of chemical liquid products. In order to prevent grinding media such as zirconia beads from being discharged together with the ground material, a screen is usually set on the grinding spindle to separate the slurry and grinding media. However, the screen is prone to clogging, and it is necessary to stop the machine frequently to clear the screen. In order to solve the problem of screen clogging, sand mills without screens have appeared in recent years.

[0003] During the slurry sand milling process, a slurry pump is needed to inject the slurry into the sand mill. If the plug in the slurry pump cannot move at a uniform speed, the internal volume of the pump will change unevenly when the pump inhales and discharges the fluid, which will cause pressure pulses when the slurry is output to the sand mill. That is, the slurry entering the sand mill will generate impact force. For a sand mill without a screen, the above-mentioned impact force will cause the grinding medium in the sand mill to be discharged from the sand mill, resulting in ball leakage, which affects the quality of the slurry.

[0004] Therefore, it is necessary to design a slurry pump that can provide a constant delivery flow rate for the sand mill. Summary of the invention

[0029] In order to further understand the content, features and effects of the invention of the present application, the following embodiments are cited and described in detail with reference to the accompanying drawings.

[0030] See also Figures 1 to 7, a constant-speed constant-flow pump with a vortex cam, comprising a pump body, wherein material cavities 13 are symmetrically arranged on the left and right sides of the pump body, and plugs are movably arranged in the two material cavities 13; the ends of the two plugs close to each other are fixedly connected by a connecting member 6, and a horizontal through hole 61 is opened in the middle of the connecting member 6; it also includes a horizontally arranged main shaft 5, the main shaft 5 passes through the horizontal through hole 61 and is rotatably connected to the front and rear sides of the pump body, one end of the main shaft 5 extends to the outside of the pump body and is connected to a driving mechanism; two vortex cams are arranged on the main shaft 5 along the axial direction, and contact members corresponding to the two vortex cams are respectively arranged on the connecting members 6 on the left and right sides of the main shaft 5 or on the plugs on the left and right sides of the main shaft 5. During the uniform rotation of the main shaft 5, the two vortex cams are driven to alternately contact and separate with the corresponding contact members to drive the two plugs to perform continuous uniform linear reciprocating motion.In this embodiment, the left and right sides of the pump body are symmetrically provided with a first material cavity 131 and a second material cavity 132, respectively. The first material cavity 131 is movably provided with a first plug body 12, and the second material cavity 132 is movably provided with a second plug body 22; the first plug body 12 and the second plug body 22 are fixedly connected at one end close to each other by a connecting member 6, and the first plug body 12 and the second plug body 22 are both provided with a connecting groove at one end close to each other, and the connecting member 6 is specifically a connecting plate, and connecting blocks are protruding at both ends of the connecting plate, and the connecting blocks are inserted into the connecting groove, and the connecting groove and the connecting block are fixedly connected by a fastener, so that the first plug body 12 and the second plug body 2 2, the connecting member 6 is connected together; the first vortex cam 3 and the second vortex cam 4 are sequentially arranged on the main shaft 5 along the axial direction, the first contact member 11 corresponding to the first vortex cam 3 is arranged on the connecting member 6 on the left side of the main shaft 5 or the first plug body 12, and the second contact member 21 corresponding to the second vortex cam 4 is arranged on the connecting member 6 on the right side of the main shaft 5 or the second plug body 22. During the rotation of the main shaft 5, the first vortex cam 3 is driven to contact or separate with the first contact member 11, and the second vortex cam 4 is driven to separate or contact with the second contact member 21; when the first vortex cam 3 is in contact with the first contact member 11, the first vortex cam 3 is driven to contact or separate with the first contact member 11, and the second vortex cam 4 is driven to contact or separate with the second contact member 21; when the first vortex cam 3 is in contact with the first contact member 11, the first vortex cam 3 is driven to contact with the first contact member 11. When the first vortex cam 3 is separated from the first contact piece 11 and the second vortex cam 4 is in contact with the second contact piece 21, the first vortex cam 3 drives the first contact piece 11 to move linearly to the left at a uniform speed, thereby driving the first plug body 12 and the second plug body 22 to move linearly to the left at a uniform speed simultaneously, so that the volume of the first material chamber 131 is reduced to achieve discharge and the volume of the second material chamber 132 is increased to achieve feeding; when the first vortex cam 3 is separated from the first contact piece 11 and the second vortex cam 4 is in contact with the second contact piece 21, the second vortex cam 4 drives the second contact piece 21 to move linearly to the right at a uniform speed, thereby driving the first plug body 12 and the second plug body 22 to move linearly to the right at a uniform speed simultaneously, thereby making the volume of the first material chamber 131 decrease. The volume of the first material chamber 131 increases to realize feeding, while the volume of the second material chamber 132 decreases to realize discharging; and the two states of the first vortex cam 3 contacting the first contact piece 11 and the second vortex cam 4 contacting the second contact piece 21 are seamlessly connected, so that the first plug body 12 and the second plug body 22 are driven by the main shaft 5 and the two vortex cams to perform continuous uniform linear reciprocating motion, so that the first material chamber 131 and the second material chamber 132 can be seamlessly connected with uniform speed feeding or uniform speed discharging, so that the constant flow pump in this embodiment can supply slurry to the sand mill at a continuous and constant flow rate, prevent pulse pressure from occurring during the slurry supply process, avoid the occurrence of ball leakage, and ensure the quality of the slurry discharged from the sand mill.

[0031] Specifically, each of the vortex cams is provided with two centrally symmetrical blades, and the four blades are centrally symmetrical as a whole, and each blade includes a connected contact curve segment 31 and a clearance straight line segment 32, wherein the contact curve segment 31 can contact the corresponding contact member and drive the two plug bodies to perform uniform linear motion, and the clearance straight line segment 32 does not contact the contact member. When the main shaft 5 drives the cam to rotate, the contact curve segments 31 of the blades in the two vortex cams are seamlessly connected and touch the corresponding contact members in turn, so that the plug bodies on both sides perform continuous uniform linear reciprocating motion.

[0032] More specifically, the starting point of the contact curve segment 31 of one blade in the vortex cam is connected to the end point of the clearance straight line segment 32 of another blade, and the end point of the contact curve segment 31 is connected to the starting point of the clearance straight line segment 32 of the same blade; when the starting point or end point of a contact curve segment 31 in one of the vortex cams contacts the corresponding contact piece, the end point or starting point of a contact curve segment 31 in the other vortex cam just contacts the corresponding contact piece. Therefore, when the main shaft 5 drives the cam to rotate, a contact curve segment 31 in one of the vortex cams contacts with the contact piece on the corresponding side. When the contact curve segment 31 of the vortex cam rotates to the end position and contacts with the corresponding contact piece, the starting position of a contact curve segment 31 in the other vortex cam just contacts with the contact piece on the corresponding side, and the cycle is repeated in sequence. During the time when each contact curve segment 31 contacts with the corresponding contact piece from the starting point to the end point, the rotation angle of the main shaft 5 is 90 degrees. When the main shaft 5 rotates one circle, the contact curve segments 31 of the four blades contact with the corresponding contact pieces in sequence and seamlessly, thereby realizing that the constant flow pump can supply slurry to the sand mill at a continuous and constant flow rate.

[0033] More specifically, the contact curve segment 31 is an Archimedean spiral. Since the contact curve segment 31 is an Archimedean spiral, when the main shaft 5 rotates at a constant speed, the contact curve segment 31 can drive the corresponding contact member to move at a constant speed, thereby driving the two plug bodies to reciprocate back and forth between the two material cavities 13 at a constant speed.

[0034] Specifically, the two vortex cams are respectively located at the front and rear sides of the connecting member 6, and the two contact members are rolling bearings or rollers, one of the contact members is arranged at the front side of the connecting member 6, and the other contact member is arranged at the rear side of the connecting member 6. Among them, the first vortex cam 3 and the first contact member 11 are both located at the front side of the connecting member 6, and the second vortex cam 4 and the second contact member 21 are both located at the rear side of the connecting member 6. By reasonably arranging the positions of the vortex cams and the corresponding contact members, the overall structure is more reasonable and compact.

[0035] Specifically, it also includes a feed pipe 71 and a discharge pipe 72. Each of the material chambers 13 is provided with a discharge port at the upper end and a feed port at the lower end. The two feed ports are connected to the feed pipe 71, and the two discharge ports are connected to the discharge pipe 72. Among them, the feed pipe 71 is connected to an external slurry supply mechanism, and the discharge pipe 72 is connected to an external sand mill. When the plug on one side squeezes the corresponding material chamber 13, the slurry in the corresponding material chamber 13 is pushed out to the discharge pipe 72 to realize the discharge of the slurry. At the same time, the plug on the other side gradually withdraws from the corresponding material chamber, and the internal pressure of the corresponding material chamber 13 gradually decreases, allowing the material in the feed pipe 71 to enter it, thereby realizing the feeding of the slurry; when the plug moves in the opposite direction, the feeding action and the discharging action of the two material chambers 13 are exchanged, that is, there is always one material chamber 13 in the two material chambers 13 that is feeding and the other material chamber 13 that is discharging, so that the constant flow pump in this embodiment can continuously feed from the feed pipe 71 and continuously discharge to the discharge pipe 72.

[0036] More specifically, a one-way valve 9 is provided between the two feed ports and the feed pipe 71, and between the two discharge ports and the discharge pipe 72. The one-way valve 9 between the feed port and the feed pipe 71 is used to ensure that the slurry can only flow from the feed pipe 71 to the material cavity 13, and the one-way valve 9 between the discharge port and the discharge pipe 72 is used to ensure that the slurry can only flow from the material cavity 13 to the discharge pipe 72, thereby ensuring the conveying direction of the slurry.

[0037] Specifically, it also includes a guide mechanism 8, which includes a first guide member and a second guide member that slide and cooperate with each other, the first guide member is fixedly arranged between the two material cavities 13, and the second guide member is fixedly arranged on the connecting member 6. The pump body is provided with a shell, and the shell is sleeved on the material cavity 13 and the outside of the plug body for protection, the first guide member is arranged on the inner wall of the shell and is located between the two material cavities 13, and the second guide member is fixed to the connecting member 6. The first guide member and the second guide member are provided with mutually cooperating concave and convex parts. When the plug body reciprocates back and forth between the two material cavities 13, the connecting member 6 moves synchronously to drive the second guide member to slide on the first guide member, so as to guide the reciprocating motion of the plug body, prevent the plug body from deviating during the motion, and further ensure that the plug body performs continuous uniform linear reciprocating motion.

[0038] Specifically, a sealing member 10 is provided between the plug body and the corresponding material cavity 13. A channel for the reciprocating movement of the plug body is provided on one side of the material cavity 13 close to the connecting member 6. The sealing member 10 is specifically a sealing ring, which is embedded on the inner wall of the channel to prevent the slurry in the material cavity 13 from overflowing from the gap between the plug body and the channel.

[0039] When in use, the feed pipe 71 is connected to an external slurry supply mechanism, the discharge pipe 72 is connected to an external sand mill, the external driving mechanism is started to drive the main shaft 5 to rotate, and the first vortex cam 3 and the second vortex cam 4 on the main shaft 5 rotate with the main shaft 5. When the starting point of a contact curve segment 31 of the first vortex cam 3 or the second vortex cam 4 contacts the corresponding contact member (the first vortex cam 3 is taken this time), the first contact member 11 is pushed, and the first plug body 12 is driven to squeeze the first material cavity 131. The slurry in the first material cavity 131 is restricted by the one-way valve 9, so it can only be pushed into the discharge pipe 72 and discharged to the external sand mill. At the same time, the second vortex cam 4 The first plug 12 is not in contact with the second contact piece 21, and the second plug 22 follows the first plug 12 to move to the left, so that the second plug 22 gradually withdraws from the second material chamber 132, and the pressure in the second material chamber 132 decreases. Due to the restriction of the one-way valve 9, the slurry in the external slurry supply mechanism enters the second material chamber 132; when the contact curve segment 31 of the first vortex cam 3 rotates to the end point and contacts the first contact piece 11, the starting point of one of the contact curve segments 31 of the corresponding second vortex cam 4 just contacts the second contact piece 21 of the second plug 22. As the main shaft 5 continues to rotate, the first vortex cam 3 disengages from the first contact piece 11, and the contact curve segment 31 in the second vortex cam 4 contacts the second contact piece 21. The contact piece 21 plays a pushing role, driving the second plug body 22 to squeeze the second material chamber 132. The slurry in the second material chamber 132 is also restricted by the one-way valve 9, so it can only be pushed into the discharge pipe 72 and discharged to the external sand mill. At the same time, the first plug body 12 follows the second plug body 22 to move to the left, so that the first plug body 12 gradually withdraws from the first material chamber 131, and the pressure in the first material chamber 131 decreases. Due to the restriction of the one-way valve 9, the slurry in the external slurry supply mechanism enters the first material chamber 131 through the feed pipe 71, until the contact curve segment 31 of the second vortex cam 4 rotates to the end point and contacts the second contact piece 21, the corresponding other contact curve segment 31 of the first vortex cam 3 The starting point of the line segment 31 contacts the first contact piece 11 and circulates in sequence. When the main shaft 5 rotates one circle, one cycle is completed. In one cycle, the contact curve segments 31 in the four blades are seamlessly connected with the corresponding contact pieces in sequence, thereby driving the first plug body 12 and the second plug body 22 to perform continuous uniform linear reciprocating motion through the main shaft 5 and the two vortex cams, so that the first material chamber 131 and the second material chamber 132 can be seamlessly connected with uniform speed feeding or uniform speed discharging, so that the constant flow pump can supply slurry to the sand mill at a continuous and constant flow rate, prevent pulse pressure from occurring during the slurry supply process, avoid the occurrence of ball leakage, and ensure the quality of the slurry discharged from the sand mill.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
